Description

Technical Field

[0001] This utility model relates to the field of medical supplies technology, specifically to a protective device for a temporary neck hemodialysis catheter. Background Technology

[0002] For patients requiring hemodialysis, arteriovenous fistula maturation typically takes 4-8 weeks. During the waiting period for the fistula to reach the required function, temporary vascular access is necessary for maintenance therapy. Among these options, temporary indwelling hemodialysis catheters in the neck are the most commonly used transitional access due to their ease of operation and stable blood flow.

[0003] Currently, catheter maintenance often employs multi-layered sterile gauze dressings. While this effectively blocks external contaminants, it presents significant risks in practical care: because the neck catheter is close to the hairline, the dressing easily becomes soaked during daily head cleaning. A damp dressing not only damages the local skin barrier but can also become a breeding ground for bacteria. Studies show that a damp dressing is a contributing factor to catheter-related infections, which in severe cases can lead to puncture site suppuration, bacterial colonization within the catheter, and even progression to systemic infections such as sepsis, significantly increasing the patient's hospitalization risk and medical costs. Utility Model Content

[0004] The purpose of this invention is to provide a temporary neck hemodialysis catheter protection device, which facilitates daily head cleaning for hemodialysis patients and effectively reduces the risk of infection of indwelling neck hemodialysis catheters.

[0037] Preferred embodiments of the invention will now be described with reference to the accompanying drawings. The following description, with reference to the accompanying drawings, is provided to aid in understanding exemplary embodiments of the invention as defined by the claims and their equivalents. It includes various specific details to aid understanding, but these should be considered exemplary only. Therefore, those skilled in the art will recognize that various changes and modifications can be made to the embodiments described herein without departing from the scope and spirit of the invention. Furthermore, detailed descriptions of functions and structures well known in the art will be omitted to make the specification clearer and more concise.

[0038] Arteriovenous fistulas typically mature within 4-8 weeks. During this period, temporary vascular access is required for maintenance therapy. Among these, temporary neck-dwelling hemodialysis catheters are the most commonly used transitional access due to their ease of operation and stable blood flow. Currently, catheter maintenance often involves wrapping the catheter with multiple layers of sterile gauze dressings. While this effectively blocks external contaminants, the neck catheter's proximity to the hairline makes the gauze dressings prone to wetting during routine head cleaning, posing a safety hazard. Therefore, this embodiment provides a protective device for temporary neck-dwelling hemodialysis catheters. Once applied, the device completely covers the temporary neck-dwelling hemodialysis catheter, preventing water from seeping in and avoiding wetting the gauze dressing, which could become a breeding ground for bacteria.

[0039] Example

[0040] like Figure 1 and 2 As shown, this embodiment provides a temporary neck hemodialysis catheter protection device, including a tubing 10, an impermeable membrane 20, and an adhesive 30.

[0041] Specifically, the tubing 10 is used to wrap around a portion of the hemodialysis catheter 50, thereby protecting the hemodialysis catheter 50.

[0042] Specifically, the geomembrane 20 is configured to be connected to the end of the hose 10.

[0043] Specifically, the adhesive piece 30 is used to adhere to the patient's skin. The adhesive piece 30 is fixed to the tubing 10 and the geomembrane 20 by adhesive bonding. The adhesive piece 30 is arranged in a ring shape, and the area enclosed by the adhesive piece 30 forms a receiving cavity. The tubing 10 communicates with the receiving cavity, and gauze 40 is placed inside the receiving cavity.

[0044] In this embodiment, the hose 10 and the geomembrane 20 are integrated into one piece.

[0045] In this embodiment, the adhesive component 30 is a pressure-sensitive adhesive. The pressure-sensitive adhesive has a skin-adhesive surface, on which a release liner (not shown) is provided. The pressure-sensitive adhesive has good biocompatibility, is non-irritating to human tissue, and will not cause immune responses or inflammation; it has high adhesive strength, firmly adheres to the skin surface, will not easily fall off, and also prevents liquid water from seeping in; it is easy to use, requiring only slight pressure to achieve adhesion.

[0046] In this embodiment, the hose 10 is a thin-walled polyethylene tube. The geomembrane 20 is a polyethylene film. The hose 10 and the geomembrane 20 are made of soft polyethylene, which has good waterproof properties and can effectively block the penetration of liquid water; soft polyethylene has high chemical stability and can withstand the erosion of common medical disinfectants; it is relatively inexpensive, which can reduce production costs and is easy to process and shape.

[0047] In this embodiment, the gauze 40 is fixedly connected to the geomembrane 20. The gauze 40 is not easily detached, which effectively improves ease of use.

[0048] In this embodiment, both the hose 10 and the geomembrane 20 are transparent, allowing for easy observation by the user.

[0049] In this embodiment, the area of ​​the geomembrane 20 is larger than the outer circumference area of ​​the adhesive member 30. The edge of the geomembrane 20 can adhere to the patient's skin, which can further improve the anti-seepage effect and prevent water from directly seeping into the receiving cavity due to the adhesive member 30 not being properly attached.

[0050] In this embodiment, the end of the tubing 10 is flared, which makes it easier for the user to pass the hemodialysis catheter through the tubing 10, thus improving ease of use.

[0051] In this embodiment, the length of the hose 10 is 10 centimeters and the circumference of the hose 10 is 10 centimeters.

[0052] In some embodiments not shown, the adhesive is simply fixed to the geomembrane. The geomembrane is circular with a diameter of 11 cm, and the adhesive has a diameter of 10 cm.

[0053] In some embodiments not shown, adhesive tape is applied to the geomembrane. If necessary, the tape can be used to further secure the entire device, preventing the hemodialysis catheter from swaying and causing the entire device to be pulled out, effectively improving stability and safety during use.

[0054] The present invention has been described in detail above. Specific examples have been used to illustrate the principles and implementation methods of the present invention. The description of the above embodiments is only for the purpose of helping to understand the method and core ideas of the present invention.
