Description

TECHNICAL FIELD

[0001] The utility model relates to medical auxiliary equipment technical field, concretely relates to a PORT special double -deck anti -edge curling and applies. BACKGROUND

[0002] In medical institutions, PORT (implantable central venous infusion device) is a widely used treatment method. In clinical practice, the edge curling of the patch (that is, the side or multiple side edges of the patch are raised) is a relatively common problem, which not only affects the comfort of the patient, but also has an adverse effect on the treatment effect. The reasons for this are as follows: firstly, the nursing operation is not careful, which causes the unevenness between the patch and the skin and the retention of air bubbles. Secondly, some patients sweat after taking medicine, and the sweat infiltrates the patch, causing the patch to be not firmly adhered. Therefore, how to develop a new type of PORT special patch to overcome the above problems in the prior art is the direction that needs to be researched by the person skilled in the art. CONTENT OF THE UTILITY MODEL

[0003] The utility model aims at providing a PORT special double -deck anti -edge curling and applies, which can reduce the edge curling of the patch during use, improve the comfort of the patient, and ensure the treatment effect.

[0004] The utility model discloses a PORT special double -deck anti -edge curling and applies, it includes:

[0005] The first side of the patch body is coated with adhesive glue;

[0006] The sweat -inhibiting layer is pasted and installed at the center position of the first side, and the cross section of the sweat -inhibiting layer is less than the patch body;

[0007] The needle fixing device is fixedly installed on the second side of the patch body;

[0008] The tail end of the infusion needle is fixed in the needle fixing device, the needle tip of the infusion needle penetrates the patch body and the sweat -inhibiting layer in turn, and extends out of the surface of the sweat -inhibiting layer;

[0009] The pipe body of the infusion pipe is inserted into the needle fixing device and is in conductive connection with the tail end of the infusion needle;

[0010] The fixed end of the patch flip cover is fixedly connected with the patch body as a whole, and the movable end of the patch flip cover is configured to be reversibly moved to cover the needle fixing device relative to the patch body. The patch flip cover is provided with an adhesive layer for adhering the needle fixing device.

[0011] By adopting the technical scheme, the needle tip of the infusion tube is pricked into the vein under the skin of the patient during infusion, and the first side of the patch body is pasted on the skin of the patient at the same time. At this time, the sweat-inhibiting layer is pasted on the skin near the pricking point, absorbs sweat, and prevents the sweat from infiltrating the adhesive layer on the patch, thereby causing unstable adhesion. Meanwhile, bacteria in the sweat are further prevented from causing infection at the pricking point. Finally, the movable end of the patch cover is turned relative to the patch body to cover the needle head fixer; the patch cover is glued to the side of the needle head fixer away from the patch body by the adhesive layer, thereby effectively fixing the needle head fixer and overcoming the problem of air bubbles caused by unevenness between the patch and the skin.

[0012] Preferably, the sweat-inhibiting layer is made of bamboo fiber material doped with graphene nanosheets.

[0013] By adopting the technical scheme, the bamboo fiber material itself has certain adsorption and air permeability. The graphene nanosheets have good water absorption capacity and can adsorb harmful substances discharged in sweat.

[0014] Preferably, the edge of the patch body is connected with a wave-shaped outer edge.

[0015] By adopting the technical scheme, the wave-shaped outer edge can stretch and contract with the natural movement of the skin, reduce the pulling of the patch caused by the movement of the skin, and reduce the possibility of edge curling.

[0016] More preferably, the patch body is in a rectangular sheet structure; the fixed end of the patch cover is fixedly connected with one side edge of the patch body as a whole; and the other three side edges of the patch body are respectively connected with the wave-shaped outer edges.

[0017] More preferably, the patch body is made of a breathable polymer film.

[0018] Compared with the prior art, the utility model has the following technical advantages:

[0019] Firstly, the utility model can overcome the unevenness between the patch and the skin caused by careless nursing operation.

[0020] Secondly, the utility model can absorb sweat, prevent the sweat from infiltrating the adhesive layer on the patch, thereby causing unstable adhesion, and further prevent bacteria in the sweat from infecting the pricking point.

[0021] Thirdly, the wave-shaped outer edge of the utility model can stretch and contract with the natural movement of the skin, reduce the pulling of the patch caused by the movement of the skin, and reduce the possibility of edge curling.

[0022] Finally, the hardware part of the utility model has simple structure and is easy to prepare and realize. BRIEF DESCRIPTION OF THE DRAWINGS
