As shown in FIG. 1, the sound pressure therapy apparatus 1 according to an embodiment of the present invention includes a connector 100, an aspirator 200, a drape 300, and a foam dressing 400. The connector 100 described below refers to a connector for negative pressure treatment.

Foam dressing 400 is disposed over wound W to abut the wound. Foam dressing 400 may be cut or compressed to fit the size of the wound and placed on the wound (W). The foam dressing 400 may be a porous pad that absorbs the exudates generated from the wound W or forms an amorphous flow path through which the exudates flow. The foam dressing 400 may be made of a porous hydrophobic material so that the exudate flows smoothly within the foam dressing 400.

The drape 300 adheres to the foam dressing 400 and the skin S adjacent to the wound W while the foam dressing 400 is disposed on the wound W. FIG.

As shown in FIG. 1, a first through hole 310 is formed in the drape 300. The first through hole 310 is formed to be positioned above the foam dressing 400. The first through hole 310 may be formed before the drape 300 adheres to the surface of the skin around the foam dressing 400 and the wound W. FIG. Alternatively, the first through hole 310 is formed by cutting a portion of the drape 300 after the drape 300 is adhered to the foam dressing 400 and the skin surface S around the wound W. FIG. Can be.

As shown in FIG. 1, the suction head 120 is bonded to the top of the drape 300 in a state of being coupled with the tube 130. The tube 130 may be integrally formed with the suction head 120 or may be configured to be coupled / removable to the suction head 120. When the tube 130 is configured to be coupled / removable to the suction head 120, the user fixes the suction head 120 to the drape 300 and then connects the tube 130 to the suction head 120 or the suction head 120. After combining the 120 and the tube 130, the suction head 120 may be fixed to the drape 300.

In the connector 100 illustrated in FIG. 1, the release films 141 and 142 (see FIG. 3) are removed.

Details of the other connector 100 will be described later.

As shown in FIG. 1, one end of the tube 130 is connected to the suction head 120, and the other end of the tube 130 is connected to the aspirator 200.

The aspirator 200 includes a canister 210 connected to the other end of the tube 130, a negative pressure pump 230 for generating a negative pressure, and a negative pressure flow path 230 for connecting the negative pressure pump 230 and the canister 210. . The negative pressure generated by the negative pressure pump 230 means an air pressure state lower than atmospheric pressure (760 mmHg).

The negative pressure atmosphere generated by the negative pressure pump 230 is transmitted to the canister 210 through the negative pressure passage 230, and is transferred to the suction head 120 through the tube 130 connected to the canister 210, and the suction head ( The foam dressing 20 and the wound portion W through the suction passage 123 formed in the 120, the second through hole 111 of the head adhesive film 110, and the first through hole 310 of the drape 300. Is delivered to.

As shown in FIG. 1, since the drape 300 forms a sealing space between the wound portion W and the drape 300, the wound portion W is formed by a negative pressure supplied to the sealing space by the aspirator 200. The exudates generated from the suction passages of the suction head 120 pass through the first through hole 310 of the drape 300 and the second through hole 111 of the head adhesive film 110 through the foam dressing 400. 123, and then moves along the tube 130 to the canister 210.

As a result, as shown in FIG. 1, the canister 210 receives the exudates E sucked from the wound W. As shown in FIG. The canister 210 may be configured to be detachable from the aspirator 200 so that the exudates E can be emptied at any time.

Hereinafter, a connector according to an embodiment of the present invention will be described in detail.

2 is a plan view showing a part of a connector according to an embodiment of the present invention, Figure 3 is a cross-sectional view showing a state before attachment of a connector according to an embodiment of the present invention.

2 and 3, the connector 100 according to an embodiment of the present invention may include a head adhesive film 110, a suction head 120, a tube 130, and a

release film

141, 142. Include.

The connector 100 is provided with a suction head 120 on an upper surface of the head adhesive film 110, and release

films

141 and 142 are provided on a lower surface of the head adhesive film 110.

The suction head 120 includes a flange portion 121 contacting the upper surface of the head adhesive film 110 and a body portion 122 extending upwardly from the flange portion 121.

An adhesive layer may be applied to the lower surface of the flange portion 121 so that the suction head 120 is adhered to the upper surface of the head adhesive film 110. Alternatively, an adhesive layer may be applied to the upper surface of the head adhesive film 110 so that the suction head 120 is adhered to the upper surface of the head adhesive film 110.

As shown in FIG. 3, the exudation suction hole 124 is formed in the flange portion 121. A second through hole 111 connected to the exudation suction hole 124 is formed in the head adhesive film 110. The second through hole 111 is formed in advance, or cuts a portion of the head adhesive film 110 (lower region of the exudation suction hole 124) during the process of installing the connector 100 on the upper surface of the drape 300. Can be formed in a manner.

The suction passage 123 is formed inside the body portion 122. One end of the suction passage 123 is connected to the exudation suction hole 124, and the other end is connected to the tube coupling hole 125 that is open at one side of the body portion 122.

The tube coupling hole 125 is a space in which one end of the tube 130 is coupled. As described above, the tube 130 may be integrally formed with the suction head 120 of the connector 100 or may be configured to be coupled / removable to the suction head 120.

As shown in FIG. 3, release

films

141 and 142 are provided on the bottom surface of the head adhesive film 110. The

release films

141 and 142 are for protecting the adhesive layer applied to the lower surface of the head adhesive film 110.

The

release films

141 and 142 may include a first release film 141 and a second release film 142.

The second release film 142 is attached to cover a portion of the lower surface of the head adhesive film 110, and as shown in FIG. 3, a portion of the second release film 142 is attached to the lower surface of the head adhesive film 110. It may be provided to be folded outward so as not to be attached and overlap with another part.

The first release film 141 is attached to the remaining portion of the head adhesive film 110 which is not covered by the second release film 142, and as shown in FIG. 3, a part of the first release film 141 may be a head. The second release film 142 may be covered without being attached to the bottom surface of the adhesive film 110.

Therefore, before attaching the connector 100 to the top surface of the drape 300, the user grasps a portion of the first release film 141 that is not attached to the bottom surface of the head adhesive film 110 and holds the first release film 141. Remove When the first release film 141 is removed, the second release film 142 is exposed, and the user grasps a portion of the second release film 142 that is not attached to the bottom surface of the head adhesive film 110, and then releases the second release film. 142 may be removed.

As the first release film 141 and the second release film 142 are removed, the adhesive layer formed on the bottom surface of the head adhesive film 110 is exposed, and the connector 100 is adhered to the top surface of the drape 300 to be fixed. can do.

Conventionally, the suction head is positioned on the drape and the suction head is covered with a separate drape to fix the suction head to the drape, but the connector 100 according to the present embodiment is a flange portion of the suction head 120. Since the head adhesive film 110 is attached to the lower surface in advance, the

release films

141 and 142 may be removed to directly attach and fix the suction head 120 onto the drape.

As shown in FIG. 4, the connector 100 is adhered to the top surface of the drape 300 with the

release films

141 and 142 removed.

As shown in FIG. 4, the head adhesive film 110 of the connector 100 according to the exemplary embodiment of the present invention has a thickness t2 thicker than the thickness t1 of the drape 300.

Since the head adhesive film 110 is formed thicker than the drape 300, when the head adhesive film 110 and the drape 300 are formed of the same / similar material, the head adhesive film 110 is larger than the drape 300. It has elastic force. Therefore, when the same tensile force acts on the head adhesive film 110 and the drape 300, the amount of deformation of the head adhesive film 110 becomes smaller than the amount of deformation of the drape 300.

When the elastic force of the drape and the head adhesive film is similar, the tension applied to the drape and the head adhesive film causes the drape and the head adhesive film to be deformed at the same time, thereby creating a gap between the drape and the head adhesive film and causing negative pressure leakage. This is high.

On the other hand, in the present embodiment, since the head adhesive film 110 has a larger elastic force than the drape 300, the drape is caused by an external force acting on the connector 100 while the connector 100 is mounted on the drape 300. Although the tensile force acts on the 300 and the head adhesive film 110, the portion of the drape 300 that is not in contact with the head adhesive film 110 is preferentially absorbed and deformed. Therefore, even when an external force that causes a tensile force acts on the drape 300 and the head adhesive film 110, the adhesive state between the head adhesive film 110 and the drape 300 may be maintained to prevent leakage of negative pressure.

For convenience of description, parts similar to the above-described embodiments use the same reference numerals, and parts common to the above-described embodiments will not be described.

As shown in FIG. 5, as another embodiment, the head adhesive film 110 ′ may be formed by stacking a plurality of adhesive films 110a and 110b. 5 illustrates an example in which two adhesive films 110a and 110b are stacked, but three or more adhesive films may be laminated.

As illustrated in FIG. 5, a plurality of adhesive films 110a and 110b may be stacked to form an elastic force of the head adhesive film 110 ′ larger than that of the drape 300. Each adhesive film (110a, 110b) may be composed of a film of the same material and thickness as the drape (300).

Since the head adhesive film 110 ′ according to the present embodiment also has a higher elastic force than the drape 300, the same or similar effect as the above-described embodiment may be realized.

As another embodiment, the head adhesive film may be formed of a material having a higher elastic force than the drape 300. In this case, the head adhesive film may have a higher elastic force than the drape 300 even though the head adhesive film is formed to have a thickness substantially the same as that of the drape 300.
