Description

TECHNICAL FIELD

[0001] The utility model relates to medical dressing technical field, especially a composite hydrocolloid wound dressing. BACKGROUND

[0002] The hydrocolloid dressing has strong ability of absorbing exudate of wound surface, and after absorbing the exudate, the hydrophilic particles in the dressing can form semi-solid material similar to gel, adhere to the base of the wound, provide and maintain the moist environment conducive to wound healing, and form a closed wound surface, promote the proliferation of microvessels and the formation of granulation tissue, thereby accelerating wound healing, and the closed environment is also conducive to the removal of necrotic tissue by macrophages. SUMMARY

[0003] The utility model discloses a composite hydrocolloid wound dressing, which reserves space for the expansion of the hydrocolloid by setting a buffer layer, reduces the pressure on the wound surface after the expansion of the hydrocolloid, and improves the comfort of the patient.

[0004] To achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a composite hydrocolloid wound dressing, the whole dressing is in a circular structure, comprising release paper, hydrocolloid layer, buffer layer, adhesive layer and isolation layer arranged in turn from inside to outside, the size of the hydrocolloid layer and the buffer layer is the same, the inside of the buffer layer is a hollow structure, the area of the release paper and the adhesive layer is larger than that of the buffer layer, the center part of the release paper is attached to the hydrocolloid layer, and the edge of the release paper is attached to the edge of the adhesive layer.

[0005] Optionally, the edge of the adhesive layer is uniformly provided with a plurality of adhesive strips, and the release paper is attached to the adhesive strips.

[0006] Optionally, the outer side of the isolation layer is provided with a fixing layer, the middle part of the fixing layer is attached to the isolation layer, and the edge of the fixing layer is attached to the adhesive strips.

[0007] Optionally, the hydrocolloid layer is uniformly dispersed with an antibacterial agent.

[0008] The composite hydrocolloid wound dressing has the following advantages:

[0009] (1) The buffer layer is arranged on the outer side of the hydrocolloid layer, and a space is formed in the middle part of the buffer layer, so that when the hydrocolloid layer absorbs exudate, it will expand towards the buffer layer, reduce the extrusion on the wound surface, and avoid the discomfort of the patient.

[0010] (2) The adhesive strips can reduce the adhesive area of the adhesive layer and the skin, facilitate subsequent removal of the dressing, and reduce the pain of the patient when the dressing is removed.

[0011] (3) The fixing layer can comb the adhesive strips to avoid folding and rolling when the adhesive strips are attached to the skin, thereby causing unstable connection. BRIEF DESCRIPTION OF DRAWINGS

[0012] Fig. 1 is a cross-sectional structure schematic view of the utility model.

[0013] Fig. 2 is a top view of the utility model. DETAILED DESCRIPTION

[0014] The utility model will be further described below with reference to the drawings.

[0015] As shown in Figs. 1-2 , a composite hydrocolloid wound dressing, the whole dressing is circular structure, including hydrocolloid layer 1, buffer layer 2, adhesive layer 3 and isolation layer 4 arranged in turn from inside to outside, the size of hydrocolloid layer 1 and buffer layer 2 is same, the inside of buffer layer 2 is hollow structure, provides space for the expansion of hydrocolloid, when hydrocolloid layer 1 absorbs exudate, will expand to the inside of buffer layer 2, thereby reducing the extrusion to the wound surface, avoids the discomfort of the patient. The area of adhesive layer 3 is larger than the area of buffer layer 2, the middle part of adhesive layer 3 can play a fixing role to buffer layer 2, maintains the stability of the main body of the dressing, and the edge of adhesive layer 3 is used to be attached to the skin of the patient, and the edge of adhesive layer 3 is also uniformly provided with a plurality of adhesive strips 7, by shortening the width of the edge of adhesive layer 3 and cooperating with adhesive strips 7, the tightness of the connection between the dressing and the skin can be ensured, and the adhesive strips 7 can reduce the area of the adhesion between the dressing and the skin, reduce the pain caused to the patient when the dressing is replaced or removed. Isolation layer 4 can isolate the wound surface from the external environment, avoid the infection of the external environment to the wound surface, and cooperate with the antibacterial agent in hydrocolloid layer 1 to provide a good closed and sterile environment for the wound surface, which is beneficial to the rapid healing of the wound surface. The inner side of hydrocolloid layer 1 is provided with release paper 5, the outer side of isolation layer 4 is provided with fixing layer 6, the inner side of release paper 5 is attached to adhesive layer 3 and adhesive strips 7, the adhesion of adhesive layer 3 and adhesive strips 7 is isolated, the outer side of fixing layer 6 is attached to adhesive layer 3 and adhesive strips 7, for keeping the stability of adhesive strips 7, avoiding the folding and rolling of adhesive strips 7, and affecting the adhesion of the dressing and the skin.

[0016] When using the dressing, firstly, the release paper 5 is opened, the hydrocolloid layer 1 is placed on the wound position, then the edges of the adhesive layer 3 and the adhesive strips 7 are pressed gently to adhere firmly on the skin surface, and finally the fixing layer 6 is opened; when removing the dressing, firstly, the adhesive strips 7 are opened, and then the edges of the adhesive layer 3 are opened slowly to reduce the pain of the patient.

[0017] The above-described embodiments are only some of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all the other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the present application.
