Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a tube adapter for a vacuum pressure wound,

More particularly, the present invention relates to a sound pressure therapy device for treating a wound by using a negative pressure atmosphere, and a sound pressure therapy device connected to the sound pressure therapy device for delivering a negative pressure atmosphere to a wound site, The present invention relates to a tube adapter for treating a negative pressure wound, which is fixed to a wound site so as to minimize the pressure applied to the wound.

Various studies and clinical results have shown that the application of sound pressure to tissue sites promotes the formation of granular tissue. And, a sound pressure therapy apparatus which applies this phenomenon to a medical field is being used.

The sound pressure treatment device applies sound pressure to the wound area to inhale exudates such as pus or sausage that occur at the wound area, and promotes wound healing by promoting the granulation tissue formation at the wound area.

1, the conventional sound pressure therapy apparatus includes a sound pressure generating unit 6 provided with a sound pressure motor for generating sound pressure, a tube 4b for transmitting the sound pressure atmosphere generated by the sound pressure generating unit 6 to the wound, And a tube adapter 4 disposed on the wound side and coupled with the tube 4b. The tube adapter is also called a connector, a head, and the like. The conventional tube adapter 4 is made of hard material having high hardness.

The tube adapter 4 is sealed with respect to the surrounding environment together with the wound site 2 by the band 5 so that the negative pressure atmosphere transmitted through the tube 4b is efficiently transmitted to the wound side as shown in Fig. . The band 5 is formed with an adhesive layer on the skin adhesive surface so that the tube adapter 4 can be fixed to the skin 1.

When the negative pressure atmosphere is transmitted to the tube 4b through the negative pressure generating unit and the negative pressure atmosphere is transferred to the foam dressing 3, the negative pressure is generated by the vacuum pressure due to the sealing between the foam dressing 3 and the tube adapter 4 4 is applied, and the tube adapter 4 is moved in the F2 direction to press the wound site 2.

The conventional tube adapter 4 has a hard material so that when the tube adapter 4 is pressed in the F2 direction by the positive pressure applied to the tube adapter 4, The capillary tube of the portion is pressed by the positive pressure applied by the tube adapter 4. If such a situation occurs in a patient whose blood circulation is not smooth like a diabetic patient, blood flow through the capillary blood vessel is not smoothly carried out, resulting in delayed granulation tissue formation on the wound side or tissue necrosis in severe case.

[ This is so that when the negative pressure atmosphere is provided to the foam dressing 3, the exudate 161 flowing into the body portion 111 via the foam dressing 3 flows into the tube 120 more smoothly.

Hereinafter, the order in which the tube adapter 110 for treating a negative pressure wound is attached to a wound site 2 will be described.

First, the foam dressing 3 is placed on the skin 1 so as to cover the wound area 2. The body portion 111 of the tube adapter 110 for treating a sound pressure wound is placed on the upper portion of the sealing drape 119 or inserted into the through hole 119a so as to communicate with the through hole 119a of the sealing drape 119, Is placed in contact with the dressing (3). Thereafter, the first b-type release film 115b adhered to the first b-projecting portion 113b of the first fixed drape 113 is separated from the first b-projecting portion 113b. The first fixed drape 113 is adhered to the upper surface of the sealing drape 119 by the first b adhesive layer of the first b protrusion 113b to remove the body portion 111 from the sealing drape 119 ). When the sealing drape 119 is not present, the first fixed drape 113 is adhered to the skin 1 while covering a part of the foam dressing 3, so that the body part 111 is adhered to the skin dressing 3 It can be fixed to the upper part.

The second fixed drape 114 is adhered to the sealing drape 119 in the same manner that the first fixed drape 113 is adhered to the sealing drape 119. [ In order to avoid repetition of the description, a description thereof will be omitted here.

When the body part 111 is placed on the top of the foam dressing 3 by the first fixed drape 113 and the second fixed drape 114, the first protective film (not shown) attached to the outer surface of the first fixed drape 113 116a are separated from the first fixed drape 113 and the second protective film 116b is separated from the second fixed drape 114. [

When the tube adapter 110 for treating a negative pressure wound is placed on the wound site 2 by the above process, the negative pressure generating unit 150 is operated. The negative pressure atmosphere transferred through the tube 120 during operation of the negative pressure generating unit 150 sucks the exudate 161 absorbed by the foam dressing 3 in the F1 direction. At this time, the exudate 161 of the wound area 2 flows along the tube 120 via the foam dressing 3 and the body part 111 and is received in the canister 160.

5 and 6, in the process of removing the exudate 161 of the wound site 2 using the adapter of the tube 120 according to the related art, In the process of removing the exudate 161 of the wound site 2 using the oxygen partial pressure (TcPO 2 ) and the tube adapter 110 for treating a negative pressure wound according to an embodiment of the present invention, The percutaneous oxygen partial pressure (TcPO 2 ) of the percutaneous absorption layer 2 will be described.

6 (a) shows a case where the tube adapter 110 for treating a negative pressure wound according to the embodiment of the present invention is wound around a wound site (FIG. 5 (a) 5 (b) and 6 (b) schematically show a state in which a negative pressure wound healing tube adapter 110 is provided to the wound site 2, Figure 3 is a schematic diagram of an experimental graph of the force exerted by the tube adapter 110 against the wound site 2; Here, the abscissa of the graph of Fig. 5 (b) and Fig. 6 (b) is the time lapse axis and the ordinate is the transdermal inductive peroxide partial pressure (TcPO2). The graphs of FIG. 5 (b) and FIG. 6 (b) are graphs that were performed under the same experimental conditions only with different tube adapters used.

As shown in FIG. 5 (b), when NPWT is started using a conventional tube 120 adapter, transcutaneous percutaneous oxygen partial pressure (TcPO 2 ) is measured before and after NPWT And it drops sharply to about 84%.

6 (b), when the negative pressure wound treatment (NPWT) is started using the tube adapter 110 for treating a negative pressure wound according to an embodiment of the present invention, the transcutaneous percutaneous oxygen partial pressure (TcPO 2 is about 24% lower than before and after the NPWT, which indicates that the wound is pressed by only about 1/4 of the conventional tube 120 adapter.

This is because the body part 111 is fixed to the skin 1 by using the fixed drapes 113 and 114 and the sealing drape 119 in contrast to the conventional adapter 120 made of a hard material, When the negative pressure atmosphere sucks the exudate 161 of the wound site 2 during operation of the wound dresser 100, the foam dressing 3 is lifted up to the wound area 2 in the direction F1 of movement of the exudate 161 114 between the fixed drapes 113, 114 and the skin 1 during the process of fixing the body portion 111 to the foam dressing 3 while the fixed drapes 113, The fixed drapes 113 and 114 and the sealing drape 119 are made of a flexible material so that the positive pressure for pressing the skin 1 can not be applied to the skin 1 even if the fixed drapes 113 and 114 press the skin 1 while the space is in a vacuum state. Of the tube adapter.

Accordingly, as can be seen from the graph shown in FIG. 6 (b), the present invention can prevent the exudate of the wound site 2 while minimizing the pressure of the wound area 2 when a negative pressure atmosphere is delivered to the wound area 2 161 are removed. Accordingly, the present invention is capable of minimizing the pressure applied to the capillary blood vessel existing in the wound site (2) at the time of NPWT in a patient whose blood circulation is not smooth like a diabetic patient, It is possible to smoothly supply oxygen to muscles and skin (1) tissues through the capillary blood vessels, thereby rapidly restoring the parenchyma tissue at the wound site (2).

Further, the present invention can vary the size and shape of the body part 111 so that the wound part 2 can be adhered anywhere, large or small, so that the operator can more effectively treat the exudate 161 .

It will be understood by those skilled in the art that the present invention may be embodied in other specific forms without departing from the spirit or essential characteristics thereof.
