Abstract

This invention discloses a sweat-absorbing catheter fixation membrane, comprising a main membrane, an auxiliary membrane, a water-absorbing drying pack, and a water-absorbing mesh. An auxiliary membrane is attached to the non-skin-contact side of the main membrane, and a water-absorbing drying pack is sandwiched between the auxiliary membrane and the main membrane. The upper end of the water-absorbing drying pack is adhered to the auxiliary membrane. The main membrane has a through-hole, which is covered by the water-absorbing drying pack. A water-absorbing mesh is adhered to the skin-contact side of the main membrane. The water-absorbing mesh consists of several first absorbent strips and several second absorbent strips, all of which are interwoven into a mesh structure. At least one first absorbent strip and at least one second absorbent strip cross the through-hole. By placing the water-absorbing drying pack between the main membrane and the auxiliary membrane, and in conjunction with the through-hole on the main membrane, the water-absorbing drying pack can absorb sweat or other liquids secreted by the skin in the area where the fixation membrane is attached, keeping the skin dry and preventing the fixation membrane from easily loosening.

Description

[Technical Field]

[0001] This invention relates to the technical field of medical products, and in particular to the technical field of catheter fixation membranes. [Background Technology]

[0002] In clinical practice, situations frequently arise where PICC lines, CVCs, and drainage tubes need to be inserted into the body and remain in place for extended periods. When using PICC lines, CVCs, or drainage tubes, fixation films are necessary to secure them and prevent loosening or slippage. Patients experiencing high fever followed by sweating, those with nephrotic syndrome and edema, or those with ascites due to cirrhosis often exhibit excessive sweating or exudation, requiring frequent dressing changes. This increases the workload of clinical nurses, raises costs for patients, and carries risks of infection and tube dislodgement.

[0003] Existing patent CN213250385U discloses an adhesive-type easy-to-peel film that uses a breathable and transparent film to reduce the impact of water content on the film's adhesiveness. However, the breathability of the breathable and transparent film is still relatively poor, and its breathability is affected by the external environment. For example, when the film is covered by clothing or a blanket, its breathability becomes very poor. [Summary of the Invention]

[0004] The purpose of this invention is to solve the problems in the prior art and to propose a sweat-absorbing catheter fixation membrane that can have a good sweat and moisture absorption effect, so that sweat or other liquids secreted by the skin can be absorbed in time and the fixation membrane is not easy to loosen.

[0005] To achieve the above objectives, the present invention proposes a sweat-absorbing catheter fixation membrane, comprising a main membrane, an auxiliary membrane, a water-absorbing drying pack, and a water-absorbing net. An auxiliary membrane is attached to the non-skin-contact side of the main membrane, and a water-absorbing drying pack is sandwiched between the auxiliary membrane and the main membrane. The upper end of the water-absorbing drying pack is adhered to the auxiliary membrane. The main membrane has a through hole, which is covered by the water-absorbing drying pack. A water-absorbing net is adhered to the skin-contact side of the main membrane. The water-absorbing net consists of several first water-absorbing strips and several second water-absorbing strips. All the first water-absorbing strips and all the second water-absorbing strips are interwoven into a mesh structure. At least one first water-absorbing strip and at least one second water-absorbing strip cross the through hole.

[0006] Preferably, both the main membrane and the auxiliary membrane are breathable membranes.

[0007] Preferably, all the first absorbent strips are parallel to each other, all the second absorbent strips are parallel to each other, and the first absorbent strips are perpendicular to the second absorbent strips.

[0008] Preferably, the absorbent drying package contains absorbent silica gel particles or absorbent silica gel powder.

[0009] Preferably, the absorbent drying pack is rectangular with a circular through-hole, the diameter of which is smaller than the length of the short side of the absorbent drying pack.

[0010] Preferably, a backing plate is attached to the skin-contact side of the main membrane. The backing plate consists of a main body and a frame. A frame is fixed to one end of the main body. The frame and the main body together form a clearance groove. The main membrane is attached to the frame. The absorbent net is located in the area enclosed by the frame. The depth of the clearance groove is greater than the thickness of the absorbent net.

[0011] Preferably, the liner is provided with an anti-stick coating near the end of the main film.

[0012] Preferably, both the first absorbent strip and the second absorbent strip are sponge strips or cotton threads.

[0013] The beneficial effects of this invention are as follows: By placing the absorbent drying pack between the main film and the auxiliary film, and cooperating with the through holes on the main film, the absorbent drying pack can absorb the sweat or other liquids secreted by the skin in the area where the fixed film is attached, keeping the skin covered by the fixed film dry and preventing the fixed film from easily loosening; the absorbent net can guide the sweat or other liquids secreted by the skin in the area where the fixed film is attached to the absorbent drying pack, making it easier for the absorbent drying pack to absorb these liquids.

[0014] The features and advantages of the present invention will be described in detail through embodiments and in conjunction with the accompanying drawings. [Attached Image Description]

Detailed Implementation Methods

[0018] Example 1:

[0019] See Figure 1 , Figure 2The present invention relates to a sweat-absorbing catheter fixation membrane, comprising a main membrane 1, an auxiliary membrane 2, a water-absorbing drying pack 20, and a water-absorbing net 3. An auxiliary membrane 2 is attached to the non-skin-contact side of the main membrane 1, and a water-absorbing drying pack 20 is sandwiched between the auxiliary membrane 2 and the main membrane 1. The water-absorbing drying pack 20 contains water-absorbing silica gel particles or powder. To ensure that the water-absorbing drying pack 20 does not fall off, its upper end is adhered to the auxiliary membrane 2. The main membrane 1 has a through hole 10, which is covered by the water-absorbing drying pack 20. The water-absorbing drying pack 20 can absorb sweat or other liquids secreted by the skin, ensuring skin dryness and preventing the fixation membrane from easily loosening.

[0020] A water-absorbing net 3 is adhered to the skin-contact side of the main membrane 1. The water-absorbing net 3 is composed of several first water-absorbing strips 31 and several second water-absorbing strips 32. All the first water-absorbing strips 31 and all the second water-absorbing strips 32 are interwoven into a mesh structure. All the first water-absorbing strips 31 are parallel to each other, and all the second water-absorbing strips 32 are parallel to each other. The first water-absorbing strips 31 and the second water-absorbing strips 32 are perpendicular to each other. At least one first water-absorbing strip 31 and at least one second water-absorbing strip 32 cross the through hole 10. The first water-absorbing strips 31 and the second water-absorbing strips 32 are sponge strips. The water-absorbing net 3 can absorb the sweat or other liquids secreted by the skin. The water-absorbing drying pack 20 then absorbs the liquid on the water-absorbing net 3, ultimately keeping the skin dry and preventing the fixed membrane from loosening.

[0021] To improve the breathability of the catheter fixation membrane, both the main membrane 1 and the auxiliary membrane 2 are breathable membranes. To prevent the adhesive on the skin-contact side of the main membrane 1 from becoming too dry and losing its stickiness due to the breathable nature of the main membrane 1 and the auxiliary membrane 2, the catheter fixation membrane is sealed in a sealed packaging bag.

[0022] To ensure that the absorbent drying pack 20 does not fall out of the through hole 10, the absorbent drying pack 20 is rectangular and the through hole 10 is circular, with the diameter of the through hole 10 being smaller than the length of the short side of the absorbent drying pack 20.

[0023] When the fixing film is not in use, a backing plate 4 is attached to the skin-contact side of the main film 1. The backing plate 4 consists of a main body 41 and a frame 42. A frame 42 is fixed to one end of the main body 41. The frame 42 and the main body 41 together form a relief groove 40. The main film 1 is attached to the frame 42. The absorbent net 3 is located in the area enclosed by the frame 42. The depth of the relief groove 40 is greater than the thickness of the absorbent net 3, so the absorbent net 3 can be suspended. The end of the backing plate 4 near the main film 1 is provided with an anti-stick coating, so that when the fixing film is not in use, the main film 1 is not prone to excessive wrinkles due to the presence of the absorbent net 3, making it easy for the fixing film to adhere to the skin when in use.

[0024] Example 2:

[0025] The difference between this embodiment and Embodiment 1 is that the first absorbent strip 31 and the second absorbent strip 32 in this embodiment are cotton threads. When cotton threads are used, the first absorbent strip 31 and the second absorbent strip 32 can be made thinner, which effectively reduces the overall thickness of the fixed film and makes production more convenient.

[0026] Working process of this invention:

[0027] In the operation of this invention, the sweat-absorbing catheter fixation membrane is used by separating the main membrane 1 from the liner 4 when needed, and then attaching the main membrane 1 to the area where it needs to be applied. When the skin secretes sweat or other liquids, these liquids are first absorbed by the absorbent net 3. Since the first absorbent strip 31 and the second absorbent strip 32, which make up part of the absorbent net 3, cross the through hole 10, and the main membrane 1 is very thin, this part of the absorbent net 3 comes into contact with the absorbent drying pack 20. The absorbent drying pack 20 can absorb the liquid on the absorbent net 3, so that the absorbent net 3 can maintain a good liquid absorption capacity, keeping the skin dry and preventing the fixation membrane from falling off.

[0028] The above embodiments are illustrative of the present invention and are not intended to limit the present invention. Any simple modifications to the present invention are within the scope of protection of the present invention.
