Description

Dressing Agent {Dressing}

The present invention relates to a dressing agent, and specifically, the exudates generated can be quickly controlled between a wet state and a dry state, can easily maintain the shape of a product, and deform when a wound is treated using negative pressure. The present invention relates to a dressing agent having an improved structure so as to minimize the problem.

Humans are composed of various tissues, and skin is one of them.

Skin protects the human body from external stimuli, prevents water loss, and has important life protection functions such as body temperature control and bacterial invasion prevention. When the skin is damaged due to burns or various traumas, its protective action is lost, resulting in impaired function, and various side effects due to water loss and bacterial infection from the outside make it difficult or secondary to treat the affected area. Additional side effects such as phosphorus dysfunction or damage are caused. In severe cases, it may also affect life extension.

Therefore, it is desirable to expedite the healing of wounds and to minimize secondary side effects. These wounds appear as wounds in which tissue continuity is destroyed by external pressure. Wounds include abrasions, bruises, lacerations, cuts made by blades, spear, spear, mules, wide windows and school windows. In these wounds, the following occurs:

Invasion of bacteria from external sources into the wound typically causes inflammation that activates the patient's immune response, ie, causes leukocyte cells, including neutrophil granular leukocytes, to migrate towards the inflammatory source. While it fights pathogens, these neutrophils also release inflammatory cytokines and enzymes that damage cells. In particular, neutrophils produce an enzyme called myeloperoxidase, which in turn produces a reactive oxygen species that is metabolized to kill bacteria. Equivalently, such enzymes, reactive oxygen and the like damage cells at the periphery of the wound (called "periwound"), thereby facilitating treatment, such as DNA, lipids, proteins, extracellular matrix and cytokines. Impair cell proliferation and wound closure. Since neutrophils remain longer in chronic wounds than acute wounds, this causes higher levels of inflammation. In addition, the persistent inflammatory phase of chronic wounds is caused by an effusion (fluid flowing out of the wound) with a high concentration of matrix metalloproteases (MMP). Excessive MMPs cause deterioration of extracellular matrix proteins. In addition to damaging the wound, exudate also damages the tissue surrounding the wound that is exposed to it. In particular, effusion from the wound and towards the periphery of the wound may damage the delicate skin, which has already been immune-reduced by patients experiencing underlying etiology such as diabetes. This damage degrades the skin around the wound, causing it to weaken and become a wound again. Thus, the effusion that flows into the periphery region of the wound will cause a number of complications, including the possibility of increasing the wound size and prolonging its healing.

Conventional wound treatments include covering the wound with a dressing agent to prevent further contamination and infection, to retain moisture, and to absorb exudates. Even if the exudate contains biochemical compounds that are beneficial for wound healing as described above, the exudate in the wound is excessive or its presence in the periphery of the wound facilitates tissue deterioration, and the exudate further provides growth medium for bacteria. Can act as The consistency of the effusion varies depending on the type of wound and the stage of healing. For example, the effluent may be watery, extremely viscous, or in some cases, intermediate. In addition, the size of the wound may vary considerably, depending on its healing.

And the ability to maintain adequate moisture at the contact surface with the wound, the ability to absorb exudates that occur in the wound, the ease of attachment and removal to the wound, the ability to transfer gases and vapors to the outside, the insulation from the outside, and the invasion of bacteria. Defense, defense against the human body, whether to be toxic to the human body, economical, etc. may be a requirement to choose a dressing agent.

In addition, applying such negative pressure to the wound tissue site during the wound healing method can increase and promote the growth of new tissue at the tissue site. It is known that such treatment (sometimes called "negative pressure wound therapy", "reduced pressure therapy" or "vacuum therapy" in the medical community) can lead to faster treatment. However, such negative pressure wound therapy has a problem that it is expensive, and equipment and the like are difficult to apply universally.

Here, when the dressing agent is used, it is desirable to be able to easily discharge the exudates generated from the wound to prevent skin sores and swelling, and to maintain a constant form without deformation even when used for a long time. In addition, it is preferable that the dressing agent used in the negative pressure wound therapy does not cause deformation such as crushing even when negative pressure is applied.

The dressing agent 100 according to an embodiment of the present invention will be described in detail with reference to FIGS. 1 to 5.

1 is an exploded perspective view of a dressing agent according to an embodiment of the present invention, Figure 2 is a cross-sectional view of Figure 1, Figure 3 is a conceptual diagram for explaining the operation of the dressing agent, Figure 4a to 4c the present invention A cross-sectional view of a dressing agent according to another embodiment of FIG. 5 is a schematic diagram illustrating a process in which the dressing agent is used under negative pressure.

The dressing agent 100 is configured to cover the wound so that the wound can be quickly healed, and as shown in FIGS. 1 and 2, the absorbent layer 110 absorbing the exudates generated from the wound; An upper layer 130 coupled to an upper side of the absorbing layer 110; A lower layer 150 coupled to the lower side of the absorbent layer 110 to be in contact with the wound; And a through part 170 formed through the lower layer 150, the absorbing layer 110, and the upper layer 130. In addition, the dressing agent 400, as shown in Figure 4b, more preferably comprises a pore 160, the support 180, and the auxiliary absorption layer 410.

The dressing agent 100 helps to speed up the wound healing as described above, and the dressing agent 100 may be replaced, so it is desirable to reduce pain upon replacement. For rapid treatment, it is preferable to quickly discharge the exudates excessively absorbed in the absorbent layer 110 to the outside. Because, excessive moisture in the exudate can cause softening or soreness, including the soaking of the skin, such softening or soreness lowers the integrity of the skin and physically attack the skin in the area around the wound (see 'P' in Figure 3) Or susceptible to infection and slows the process of epithelial regeneration of the wound. Of course, it is also effective in wound healing that moisture is retained in the absorbent layer 110 to an appropriate degree.

Absorption layer 110 is preferably made of a known material that is provided in the form of a plate having a certain elasticity and having a certain thickness to absorb the effusion flowing out of the wound. Absorption layer 110 may include, for example, a foam formulation having a fluffy polyurethane cushion, a hydrocolloid or hydrogel formulation consisting of gelatin, carboxymethylcellulose, pectin, but the absorption layer 110 according to the present invention. It is preferably composed of silver hydrocolloid or hydrogel formulations. In other words, it is thinner than foam but thicker and softer than bandage, and can be combined with effusion to form colloid. In this case, when there is a large amount of effusion in the wound, as described below, the sorbent may not be absorbed only by the absorbent layer 110 made of a colloidal gel. However, the absorbing layer 110 may be selected from a variety of known materials in a range that does not impair the technical spirit of the present invention.

As described later, the absorber layer 110 includes an absorbent through part 170 and an absorbent support part 180 that penetrate up and down.

The upper layer 130 is preferably coated to protect the absorber layer 110, prevent excessive evaporation of moisture, and prevent invasion of germs from the outside. Due to this coating, the upper layer 130 may not easily pass through moisture or air.

In order to solve this problem, the plurality of pores 160 are evenly penetrated in the upper surface of the upper layer 130, the plurality of pores 160 are moved to the upper side of the absorber layer 110. Can be a passage for discharging the effluent to the outside to promote the evaporation of the effluent. In addition, the upper layer 130 is penetrated through the upper through portion 173 and the upper support portion 183, respectively, as will be described later.

The lower layer 150 may be bonded to the lower portion of the absorbent layer 110 to be coated to prevent damage to the tissue of the skin or prevent sticking to the skin in a dry state when the dressing agent 100 is separated from the skin. . Due to this coating, the passage of moisture or air in the lower layer 150 is not easy.

In order to solve this problem, a plurality of pores 160 are uniformly disposed on the plate surface of the lower layer 150 in the lower layer 150, and the plurality of pores 160 have moisture from the wound to the absorbing layer 110. It can be a moving passage to promote the movement of the exudate. In addition, the lower through portion 175 and the lower support portion 185 are respectively penetrated and coupled to the upper layer 130 as described below.

The penetrating portion 170 penetrates all of the upper layer 130, the absorbing layer 110, and the lower layer 150, and is preferably arranged at regular intervals on the plate surface of the dressing agent 100 if possible. In the through part 170, the absorption through part 171, the upper through part 173, and the lower through part 175 are connected up and down.

The penetrating portion 170 penetrates the lower layer 150, the absorbing layer 110, and the upper layer 130, and may be a passage through which external air may contact the skin indirectly, and the effusion solution flows out into the cylindrical wall of the penetrating portion 170. It also serves as a passage through which moisture is discharged to the outside. That is, the through part 170 may be formed to maximize the area contacted with the outside air and the lower layer 150, the absorbing layer 110, and the upper layer 130, thereby promoting evaporation of moisture or exudates. Just as the heat transfer area is increased in the heat exchanger to increase the heat transfer effect, the evaporation effect can be increased by maximizing the area where the evaporation takes place.

Here, the structure of the penetrating portion 170, the upper layer 130, the lower layer 150 and the absorber layer 110 is not integrally penetrated in the vertical direction as needed, the absorber layer 110 and the upper layer 130 or the absorber layer. It is provided only on the 110 and the lower layer 150 (see '770a' and '770b' of Figure 4c) is not completely penetrated in the up and down direction can prevent the outside air, germs, etc. directly contact the wound site. . In addition, the size of the penetrated hole of the penetrating portion 170 may be formed such that the center area is large and the border area is smaller than the center area, or vice versa.

On the other hand, the penetrating portion 170 may be used as a passage for injecting antibiotics, stem cells, washing solution, etc. through injection to the skin or wound, the user of the dressing agent 100, including doctors, nurses.

On the other hand, when the penetrating portion 170 is hollow, the center is empty, so the air permeability can be absorbed and the flow of air is the same as or higher than that of the absorbent layer 110, which can occur faster than the absorbent layer 110. It is preferable to detachably attach the wick (not shown) having high air permeability to the hollow. By this structure, the wick is coupled to the hollow as needed to absorb the effluent and at the same time the air can be moved quickly. When the user injects the liquid as needed, the wick is separated and the syringe is inserted into the hollow of the support 170. To inject the desired liquid.

The support unit 180 may be provided in various forms, but if possible, is coupled to a through hole (not shown) formed at regular intervals at the same position on the plate surface of the upper layer 130, the absorbing layer 110, and the lower layer 150 at regular intervals. It is desirable to be. The support part 180 is divided into an upper support part 183, a lower support part 185, and an absorbent support part 181, but is preferably formed in one piece.

However, the structure of the support unit 180 is that the upper support unit 183, the lower support unit 185, and the absorbent support unit 181 are not integrally penetrated in the vertical direction as necessary, and the absorption support unit 181 and the upper support unit ( 183) or only the absorption support 181 and the lower support 185 (see '780' in Figure 4c) is not completely penetrated in the vertical direction to prevent outside air, germs, etc. directly contact the wound area Can be. In addition, the size of the penetrated hole of the support unit 180 may be smaller than the center area as necessary, so that the edge area may be larger than the center area, or vice versa, and the holes may be irregularly arranged.

The support 180 may have a hollow pipe shape 180 as shown in FIG. 4A and may be provided in a rod shape in which the center of the polygon including the circle is not empty. Of course, the cross section of the support 180 may be provided in various forms including a circle. The support unit 180 preferably has a strength that can resist pressure in the vertical direction rather than the absorbent layer 110 having a cushion. The material of the support unit 180 may include plastic and may include, for example, silicon, PE, and PP.

Since the support 180 is disposed at equal intervals between the upper layer 130 and the lower layer 150, the dressing agent 100 does not sag even if the exudant is excessively absorbed as a whole, and a change in thickness does not occur. That is, since the thickness or structure of the absorbent layer 110 can be kept constant, the size of the fine pores of the absorbent layer 110 having a myriad of pores can be maintained without reducing the size thereof. Thus, since the pore size does not change, the effluent is more effectively absorbed through the pores that are not reduced, and the absorbed effluent can be easily and quickly discharged to the outside through the pores that are not reduced.

The absorber layer 110 closer to the upper layer 130 is dried by the support 180 than the absorber layer 110 close to the lower layer 150, and the difference in moisture causes the capillary phenomenon to be further promoted inside the absorbent layer 110. Even if the exudates are excessively generated, evaporation or discharge of the exudates to the water can be performed quickly.

In addition, when the support 180 is hollow, as described above, the drug or the like may be injected through the support 180 with a syringe or the like in various forms including an injection solution from the outside. In addition, the space inside the support 180 may be a passage through which air flows to the skin or the wound side, thereby facilitating evaporation of the water to the exudates.

In addition, since the support part 180 is also hollow in the middle, the air permeability of the absorbent layer 110 may be the same as or higher than that of the absorbent layer 110, which may absorb the exudates while the flow of air may occur faster than the absorbent layer 110. It is preferable to detachably attach the wick (not shown) to the hollow.

Referring to Figure 3 describes the operation of the dressing agent 100 according to an embodiment of the present invention.

A user, including a doctor and a nurse, removes the dressing agent 100 from a not-shown wrapping paper in which the dressing agent 100 is accommodated therein in a sealed and sterilized state (see 'W' in FIG. 3A) and a wound. Cover the periphery (see 'P' in FIG. 3A).

Then, the user fixes the dressing agent 100 to the wound site with a breathable band or bandage (see 'support' in FIG. 3A) as necessary so that the dressing agent 100 does not flow at the wound site.

While using the dressing agent 100 fixed to the wound and the periphery of the wound, the exudate (see 'EX' in FIG. 3A) is wound at a flow rate that depends on various factors, including the characteristics of the wound and the consistency of the exudate. W) It flows out. Exudates EX are discharged from the wound, some of which accumulate on the wound W. As discussed above, the accumulation of excess exudate with high concentrations of MMPs causes deterioration of extracellular matrix proteins in both wounds and peri-cutaneous skin. However, the excess exudates move to the absorbent layer 110 and at the same time water vapor passes from the wound to the outside through the space of the pores 160, the penetrating portion 170 and the support 180 having the hollow ('V in FIG. 3A). As the air moves rapidly and the flow of air occurs, moisture (meaning only water in evaporate or exudates evaporated) rapidly at the top of the upper layer 130 and the absorber layer 110 ('V' in FIG. 3A). Evaporation or diffusion to the outside. As a result, the exudates may quickly move from the wet area to the dry area of the absorbent layer 110 due to capillary action. That is, due to the characteristics of the dressing agent 100 having such pores 160, the penetrating portion 170, etc., the exudant dries quickly, and the excess exudant does not exist in the absorbent layer 110, so that the skin around the wound is jammed or moisturized. This long stay prevents the skin from swelling and prevents the further generation of germs that can be caused by excessive moisture.

In addition, if necessary, as shown in FIG. 3B, when the pores 160 and the penetrating portion 170 of the dressing agent 100 are excessive, the dressing agent 195 includes an airtight member 195 including a wrap or a band through which air does not pass. The amount of water discharged by blocking the pores 160 and the penetrating portion 170 of a part of the portion 100 (refer to the 'L1' portion of two places of 'L' in FIG. 3B) can be used by limiting the amount More preferred. Here, the airtight member 195 may include, for example, an OP SITE product in a wrap shape sterilized without passing air.

That is, the dressing agent 100 according to the present invention having such a configuration may keep the dried out by rapidly evaporating the exudate if necessary, or wet the dressing agent 100 using the airtight member 195 as necessary. You can also keep it. Therefore, depending on whether the airtight member 195 is attached by using one dressing agent 100, the function of the dry dressing agent 100 and the wet dressing agent may be simultaneously performed. And, according to the present invention, there is an advantage that through the conversion of the wound into a dry state and wet state can heal the wound more effectively and heal the wound more quickly.

Dressing agents 300 and 400 according to another embodiment and another embodiment of the present invention, as shown in Figure 4a and 4b, there is no lower layer 150, or further includes an auxiliary absorption layer 410 It features.

First, as shown in FIG. 4A, the dressing agent 300 according to another embodiment of the present invention, particularly, does not cause damage to skin tissue when separated from the skin, or a very small amount of exudate is generated when the lower layer ( 150 is omitted and the absorbing layer 110 is in direct contact with the skin.

Of course, in this case, as described below, the auxiliary absorption layer 410 may be further included below the absorption layer 110.

In addition, as described above, the support parts 180 and 380 of the present exemplary embodiment may be a rod-shaped support part 380 without a hollow part and a pipe-shaped support part 180 with a hollow part. Although not shown, the through part (not shown) of the above-described embodiment may be provided in the dressing agent 300 according to the present embodiment.

Next, the dressing agent 400 according to another embodiment of the present invention as shown in FIG. 4B is different from the above-described embodiment in which the auxiliary absorbing layer 410 is provided below the lower layer 150.

Here, the auxiliary absorption layer 410 to be used includes, for example, alginate (Alginate), in particular, it is more preferable that the auxiliary absorption layer 410 is an alginate containing silver (Ag). Alginate is preferably composed of the natural material constituting the cell membrane and the intercellular membrane of the brown algae which is the most distributed among marine life. In addition, alginate in contact with the skin has excellent hydrophilicity and biocompatibility, absorbs blood or exudate from the wound area, maintains adhesion and moist environment with the wound surface, accelerates epithelialization and granulation tissue. It is desirable because it can help to promote the formation of.

That is, in case of excessive exudates from the wound, it is preferable that the auxiliary absorption layer 410 is positioned on the lower side of the lower layer 150 (not shown, but the lower side of the absorbing layer 110 in the absence of the lower layer 150) to be in contact with the skin. .

In addition, another embodiment of the auxiliary absorption layer 410 is preferably a structure that is coated or coated with a formulation containing beta glucan and / or aloe components to promote the regeneration of the skin or soft tissues and relieve inflammation.

The exudates absorbed much in the auxiliary absorption layer 410 may be discharged to the outside through the pores 160, the penetrating portion 170, the hollow support 180, so that the excess exudates do not exist in the dressing agent 100 as it is. This can help prevent skin sores and soreness.

4C illustrates another example of the dressing agent 700 as described above, in which the through parts 170, 770a, and 770b and the support parts 180 and 780 are not entirely penetrated. By this configuration, it is possible to prevent external air from directly contacting the wound, thereby preventing contamination of germs and the like.

The dressing agent 500 of another embodiment of the present invention can also be used for negative pressure wound therapy, as shown in FIG. 5. In this case, the dressing agent 100 on the plate preferably further includes a support member 550 for reinforcing the upper and lower sides of the dressing agent 100 so as not to bend or bend, for example, under plate pressure. The dressing agent 500 further includes a tube 531, a vacuum generator 533, and a one-way valve 535 that further includes a vacuum generator 530 and an airtight cover 510 for generating and maintaining a vacuum. It is preferable.

In other words, the support member 550 is not deformed even if a negative pressure acts on the dressing agent 100 and the dressing agent 100 is horizontally maintained in a plate shape so that the dressing agent 100 is not bent toward the wound side if possible. It is preferable that the upper side of the 130 and the lower side of the lower layer 150 are supported. The support member 550 includes, for example, a non-extensible mesh, and the material of the mesh preferably includes one of metal, nylon, and polyester.

By this structure, when the user applies the negative pressure by using the dressing agent 100 on the wound, it does not cause the deformation of the dressing agent 100 more effectively, so that the dressing agent 100 has its natural absorption ability and the ability to pass through the exudates. It is possible to keep the excess exudates more effectively. This effect of course allows for faster wound healing than conventional negative pressure treatment.

In the dressing agent 500 having such a configuration, as shown in FIG. 5, a sponge or the like is placed on the wound and the dressing agent 100 according to the present invention is placed thereon and contacted with the skin. Thereafter, an airtight cover 510 including a wrap that keeps airtight through air is covered on the dressing agent 100 and adhered to the skin. The airtight cover 510 is coupled to the tube 531 which is a passage for discharging the air of the wound site, the negative pressure on the wound side by discharging air from the wound and dressing agent 100 side to the outside of the end of the tube 531 There is a vacuum generator (533) to form a, one-way valve (535) for maintaining a constant vacuum generated by the vacuum generator 533 is coupled to the midstream side of the tube (531). By this structure, the user can easily form a vacuum on the wound or the dressing agent 100 side. Even if such a negative pressure is applied, the deformation of the dressing agent 100 may be prevented by the support unit 180 and the support member 550, so that the dressing agent 100 may maintain the above-described effects in the same manner as the normal pressure even under negative pressure. .

Accordingly, according to the present invention, it is possible to provide a dressing agent which is quick and easy to switch between a wet state and a dry state and prevents a phenomenon in which a wound site is bitten or called due to the exudates generated in the wound.

In addition, it is possible to provide a dressing agent capable of stably maintaining the absorption ability of the exudate by preventing deformation of the dressing agent even when used for a long time.

In addition, it is possible to simply and conveniently cope with changes in the amount of exudates generated, it is possible to provide a dressing agent that can minimize the deformation under negative pressure.

In addition, through a single through-hole through the air and the liquid containing the necessary antibiotics can be injected simply and conveniently to the wound site, to provide a multi-purpose dressing agent that can perform a variety of functions in a simple structure Can be.

While various embodiments of the present invention have been illustrated and described herein, it will be apparent to those skilled in the art that the present invention may be modified without departing from the spirit or spirit of the invention.
