Decompression dressing for indwelling catheter

Abstract

The utility model discloses a colloid dressing for decompressing an indwelling catheter. The colloid dressing comprises a polyurethane foam layer, a porous silicone adhesive layer and a release paper layer. The catheter decompression dressing is of a circular structure, after the release paper layer is torn off, the porous silicone adhesive layer is downwards adhered to the lower portion of the artery puncture catheter, and the polyurethane foam layer is soft, so that the artery puncture catheter is not directly fixed to the skin, and the effect of preventing pressure injury is achieved.

Description

Technical Field

[0001] The utility model belongs to the technical field of medical appliances, and in particular relates to a colloid dressing used for decompression of an indwelling catheter. Background Art

[0002] Indwelling catheters are increasingly used in clinical practice because of their advantages. Arterial puncture blood pressure monitoring catheters can monitor changes in the vital signs of critically ill patients at all times, and can also be used for blood draws, alleviating the pain of frequent needle pricks for patients and reducing the workload of medical staff. This type of indwelling catheter has the advantage of a longer usable time. Since the indwelling catheter is made of a harder material, it cannot be moved after being fixed with a transparent film. The local skin is under long-term pressure, which can cause the patient's skin to become sunken and red, and even cause pressure injuries. Therefore, it is necessary to design a simple, easy-to-use, and inexpensive device to solve the above problems. Utility Model Content

[0003] The purpose of the utility model is to solve the above problems existing in the prior art and provide a colloid dressing for decompression of an indwelling catheter, so as to reduce the risk of pressure injury.

[0004] The utility model is a decompression dressing for indwelling catheters, which comprises: a polyurethane foam layer, a porous silicone adhesive layer and an anti-adhesion paper layer. The catheter decompression dressing is a circular structure with a diameter of 2 cm, a central thickness of 2 mm, and an edge thickness of 1 mm. The porous silicone adhesive layer is located on the lower side of the polyurethane foam layer, and the anti-adhesion paper layer is located on the lower side of the porous silicone adhesive layer.

[0005] Furthermore, the polyurethane foam layer is made of polyurethane foam.

[0006] Furthermore, the porous silicone adhesive layer adopts silicone adhesive with a porous structure.

[0007] Furthermore, the anti-sticking paper layer is a base paper for maintaining the stickiness of the porous silicone adhesive layer.

[0008] The utility model has the following advantages: the porous silicone adhesive layer has strong self-adhesiveness, can be repeatedly pasted, and will not stick to the wound surface, and can reduce the pain when peeling off. BRIEF DESCRIPTION OF THE DRAWINGS

[0013] Refer to Figures 1 to 3 For a indwelling catheter decompression dressing, the utility model includes: a polyurethane foam layer 1, a porous silicone adhesive layer 2 and a release paper layer 3.

[0014] The catheter decompression dressing is a circular structure with a diameter of 2 cm, a central thickness of 2 mm and an edge thickness of 1 mm. The porous silicone adhesive layer 2 is located on the lower side of the polyurethane foam layer 1.

[0015] Furthermore, the polyurethane foam layer 1 is made of polyurethane foam.

[0016] Furthermore, the porous silicone adhesive layer 2 is made of silicone adhesive with a porous structure.

[0017] Furthermore, the release paper layer 3 is a backing paper for maintaining the adhesiveness of the porous silicone adhesive layer.

[0018] The utility model has the following advantages: the polyurethane foam used in the polyurethane foam layer 1 has a smaller pore size, is softer, is not easily deformed under pressure, and has the function of preventing pressure injuries; the silicone adhesive with a porous structure used in the porous silicone adhesive layer 2 has strong self-adhesiveness, can be adhered repeatedly, and will not adhere to the wound surface, which can reduce the pain when peeled off.

[0019] The usage method of the utility model in patients is as follows

[0020] After the arterial puncture blood pressure monitoring catheterization is successful, first peel off the release paper layer 3, stick the porous silicone adhesive layer 2 of the utility model downward at a suitable position below the arterial puncture catheter 4, and finally use a transparent dressing to fix the arterial puncture blood pressure monitoring catheter. Since the hard part of the arterial puncture catheter 4 is located on the polyurethane foam layer 1, the arterial puncture catheter 4 is not directly fixed to the skin, playing a role in preventing pressure injuries.
