Description

Technical Field

[0001] The utility model relates to the technical field of medical treatment, in particular to a drainage tube wound patch. Background Art

[0002] The traditional tube wound patch is composed of only a thin sterile cotton sheet and an adhesive sterile non-woven fabric, and does not have the function of absorbing exudate. In clinical practice, the wound drainage tube punctures the skin and is only padded with sterile gauze and fixed with adhesive tape. It has the disadvantages of being easy to fall off, poor adhesive tape, and the sterile gauze being damp, which is not conducive to the sterile environment of the wound and poor patient comfort. Utility Model Content

[0003] The purpose of the utility model is to provide a drainage tube wound patch to solve the problems raised in the above background technology.

[0004] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a drainage tube wound patch, comprising a sterile non-woven bag, the sterile non-woven bag being provided with a lock edge by sewing, a drainage hole being opened at the center of the sterile non-woven bag, a permeation display ring being provided on the sterile non-woven bag around the drainage hole, a gauze-free cloth being provided inside the sterile non-woven bag by sewing, absorbent cotton being provided inside the sterile non-woven bag above the gauze-free cloth, and self-adhesive paper being provided on the lock edge.

[0005] Preferably, an adjustable gap is provided on the sterile non-woven bag at one side of the drainage hole.

[0006] Preferably, the permeation display ring is sewn with absorbent cotton, and a pH indicator is sprayed on the permeation display ring.

[0007] Preferably, the surface of the sterile non-woven bag corresponding to the permeability display ring is an open structure, and the gauze-free cloth is exposed in the opening structure.

[0008] Compared with the prior art, the utility model has the following beneficial effects: the exudate is absorbed by the absorbent cotton to prevent the exudate from contaminating the surrounding objects; secondly, the penetration display ring can intuitively understand the exudate content, which is convenient for timely replacement and reduces the workload of medical staff; the self-adhesive paper can fit the human body, has a good stabilizing effect, and prevents the exudate from flowing out from the locking periphery.

[0013] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0014] Please refer to 1-3, an embodiment of the utility model provided: a drainage tube wound patch, comprising a sterile non-woven bag 1, the sterile non-woven bag 1 is provided with a lock edge 2 by sewing, a drainage hole 3 is opened at the center of the sterile non-woven bag 1, and a permeation display ring 4 is arranged on the sterile non-woven bag 1 around the drainage hole 3, a non-gauze 5 is sewn inside the sterile non-woven bag 1, and a water-absorbing cotton 7 is arranged above the non-gauze 5 inside the sterile non-woven bag 1, and a self-adhesive paper 6 is arranged on the lock edge 2, and the self-adhesive paper 6 is located on the lock edge 2 on the back of the sterile non-woven bag 1, which is in contact with the human body. The self-adhesive paper 6 is used to relatively seal the periphery of the sterile non-woven bag 1 and the human body. When exudate flows out, the relative seal formed by the self-adhesive paper 6, the sterile non-woven bag 1 and the human body is used to seal the exudate and prevent it from flowing out of the sterile non-woven bag 1. At the same time, the absorbent cotton 7 can absorb the exudate to ensure that the wound remains dry and the patient has a good comfort experience. When the amount of exudate outflow needs to be observed, there is no need to open the sterile non-woven bag 1 to expose the wound. The penetration situation can be directly observed through the penetration display ring 4 on the sterile non-woven bag 1.

[0015] On the sterile non-woven bag 1, an adjustment gap is provided on one side of the drainage hole 3. After the drainage tube is punctured and placed, the position of the drainage tube needs to be fixed. By using the adjustment gap, the size of both sides of the adjustment gap of the sterile non-woven bag 1 is reduced to fix the position of the drainage tube.

[0016] The permeation display ring 4 is sewn with the absorbent cotton 7, and the pH indicator is sprayed on the permeation display ring 4. After the exudate is absorbed by the absorbent cotton 7, it will penetrate the permeation display ring 4. Since the exudate changes the pH value of the pH indicator, the pH indicator changes in color. The permeation display ring 4 is distributed in a ring shape on the sterile non-woven bag 1, and the range of the exudate diffusion can be intuitively observed to judge the content of the exudate. The exudate and leaked liquid can be judged according to the color change of the pH indicator. The pH value of the leaked liquid is greater than 7.4, and the pH value of the exudate is less than 7.4.

[0017] The surface of the sterile non-woven bag 1 corresponding to the permeation display ring 4 is an open structure, and the gauze 5 is exposed in the opening structure. The gauze 5 is in direct contact with the wound position, which is convenient for wound recovery.

[0018] Working principle: After puncture and placement of the drainage tube, the sterile non-woven bag 1 is brought into contact with the drainage tube by adjusting the gap to fix the relative position of the drainage tube, and then the self-adhesive paper 6 is brought into contact with the human body to ensure that the gauze-free cloth 5 is in contact with the wound position. When the exudate flows out, it will be absorbed by the absorbent cotton 7 through the gauze-free cloth 5, and the exudate will be temporarily stored in the absorbent cotton 7. As the exudate in the absorbent cotton 7 increases, the infiltration display ring 4 will come into contact with the exudate, and the exudate changes the pH value on the pH indicator, causing a color change on the infiltration display ring 4, so that the content of the exudate can be observed intuitively.
