Description

Technical Field

[0001] This utility model relates to the field of hemodialysis catheter dressings, and more particularly to a long-term hemodialysis catheter dressing. Background Technology

[0002] Hemodialysis catheters play a vital role in hemodialysis treatment, especially for patients with chronic kidney disease. Since dialysis patients often need to use hemodialysis catheters for long-term blood purification treatment, the management and protection of the catheters are particularly important.

[0003] Catheter dressings are used to secure catheters and protect the puncture site, preventing infection and catheter displacement. However, traditional catheter dressings have some problems in practical use.

[0004] In terms of fixation, traditional hemodialysis catheter dressings are generally applied directly to the catheter, with only one dressing for fixation. During fixation, the catheter must be placed first, and then the dressing must be unfolded with both hands and adhered to the patient's skin to secure the catheter. During the adhesion process, it is impossible to free one hand to hold the catheter, which poses a risk of catheter displacement and affects the fixation effect. An insecurely fixed catheter not only affects the patient's comfort but also makes it easy for the catheter to dislodge, interrupting dialysis treatment, increasing patient suffering and medical costs.

[0005] Therefore, a long-term hemodialysis catheter dressing is proposed to solve the above problems. Utility Model Content

[0006] To overcome the above shortcomings, this utility model provides a long-term hemodialysis catheter dressing, which aims to improve the problems of catheter displacement and insecure fixation caused by traditional dressing fixation methods in the prior art, which affect patient comfort and increase medical risks and costs.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: a long-term hemodialysis catheter dressing, comprising a dressing one, a dressing two fixedly connected to the rear surface of the dressing one, a fixing component provided on the lower surface of the dressing one, and an observation component provided on the inner surface of the dressing one.

[0008] The fixing component includes an adhesive layer, which is fixedly connected to the lower surface of the first dressing. A release paper is adhered to the lower surface of the adhesive layer. An adhesive is fixedly connected to the lower surface of the second dressing, and a release paper is adhered to the lower surface of the adhesive.

[0009] As a further description of the above technical solution:

[0010] The observation component includes a through-slot, which is formed on the upper surface of the dressing, and a transparent window is fixedly connected to the inner surface of the through-slot.

[0011] As a further description of the above technical solution:

[0012] The left half of the front surface of the second dressing is fixedly connected to the first dressing, and the right half of the front surface of the second dressing is separated from the first dressing.

[0013] As a further description of the above technical solution:

[0014] The second dressing is set as a square, the left and right ends of the first dressing are set as long strip protrusions, and the first dressing is integrally set as a "king" shape.

[0015] As a further description of the above technical solution:

[0016] There are two groups of the release papers, and the two groups of release papers are symmetrically distributed left and right with respect to the center line of the adhesive layer.

[0017] As a further description of the above technical solution:

[0018] The rear end of the release paper protrudes from the rear surface of the adhesive.

[0019] As a further description of the above technical solution:

[0020] The right end of the release paper on the right side protrudes from the right surface of the adhesive layer.

[0021] As a further description of the above technical solution:

[0022] The through groove is opened in a penetrating shape.

[0023] The utility model has the following beneficial effects:

[0024] 1. In the utility model, through the cooperation of the fixing components, first use the adhesive of the second dressing and the release paper for preliminary positioning. When fixing, one can free one's hands to hold the catheter to ensure that the position does not shift, and then the first dressing can be fixed through the adhesive layer, which can further enhance the fixing effect on the hemodialysis catheter, avoid catheter offset and脱出, ensure the smooth progress of dialysis treatment, and reduce the pain of patients and medical costs.

[0025] 2. In the utility model, an observation component with a transparent window is provided. Medical staff can directly check the state of the hemodialysis catheter without frequently uncovering the dressing, and can timely discover whether there is any abnormality at the puncture site. This not only reduces the chance of the puncture site being exposed to external pollutants and reduces the infection risk, but also improves the work efficiency of medical staff.

[0026] 3. In the utility model, since the first dressing is set as a "king" shape, when tearing off the first dressing later, the long strip protrusions on the first dressing can be torn up one by one, avoiding the situation of tearing up a large area at the same time, and reducing the discomfort of the patient when tearing off the first dressing later.
