Description

Technical Field

[0001] This utility model relates to the technical field of medical assistive devices, and more specifically, to a hemodialysis catheter fixator. Background Technology

[0002] Internal jugular vein catheterization is widely used in clinical practice as the preferred method for quickly establishing temporary vascular access in hemodialysis patients. After the temporary access is established, the exposed portion of the hemodialysis catheter is relatively long and heavy, so it usually needs to be properly secured. If the catheter is not properly secured, adverse events such as catheter traction and dislodgement, suture dehiscence, and local infection can easily occur.

[0003] Currently, the clinical practice for securing hemodialysis catheters typically involves wrapping the exposed portion of the catheter with sterile gauze and then securing it to the patient's neck with medical tape. However, the neck skin is prone to sweating, oiliness, and wrinkles, which can lead to poor adhesion of the tape and weak load-bearing capacity. Furthermore, the frequent movement of the neck and repeated pulling can easily cause catheter displacement and suture breakage. Utility Model Content

[0004] The purpose of this invention is to provide a hemodialysis catheter fixator that can secure the catheter, thereby solving the aforementioned technical problems.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a hemodialysis catheter fixator, wherein the hemodialysis catheter includes a catheter connector and a catheter body, the catheter connector being connected to the catheter body, and the fixator including a fixing plate, a first connecting strap, a second connecting strap, a catheter fixing seat, and a magnetic seat. The two sides of the fixing plate are respectively connected to the first connecting strap and the second connecting strap, which are detachably connected. A connector slot for placing the connector is provided on the inner side of the fixing plate. The catheter fixing seat is slidably mounted on the top of the fixing plate. A catheter fixing groove for supporting the catheter body is provided on the catheter fixing seat. The catheter fixing seat includes a support seat and a clamp. The plate has a sliding connection between the support base and the fixed plate. The two sides of the support base are hinged to the clamping plates via torsion spring shafts. The gap between the two clamping plates is a catheter fixing groove for clamping the catheter body. The top of the catheter fixing groove has an opening. The end of the catheter body away from the connecting seat extends from the connecting seat slot through the catheter fixing groove to the outside of the fixed plate. A viewing window for observing the inside of the connecting seat slot is installed on the outside of the fixed plate. The fixed plate has a magnetic connection part at the bottom of the viewing window. The magnetic connection part is magnetically engaged with the magnetic suction seat. The magnetic suction seat has a snap-fit ​​hole for snapping onto the end of the catheter body away from the connecting seat to fix the catheter body.

[0006] A further technical solution of this application: the support base is provided with an insertion hole in the guide tube fixing groove.

[0007] A further technical solution of this application: the catheter fixing seat also includes a clamping block, the clamping block is slidably connected to the insertion hole opened on the inner wall of the clamping plate, the clamping block is also connected to the insertion hole through a spring, and the clamping block is used to clamp the catheter body.

[0008] A further technical solution of this application: the first connecting strip and the second connecting strip are connected by Velcro.

[0009] A further technical solution of this application: the inner walls of the first connecting strap and the second connecting strap are detachably fitted with a sweat-absorbing inner layer.

[0010] Compared with the prior art, the technical solution provided by this utility model has the following advantages:

[0011] This invention uses a neck brace-style fixator to secure the connector. By setting a catheter fixation seat above the connector slot to fix the catheter body, it can both fix and support the catheter body. In addition, a magnetic seat is installed at the end of the catheter body, and the magnetic seat is detachably connected to the fixing plate, so as to fix the end of the catheter to the fixing plate and facilitate the removal of the catheter body from the fixing plate for connection with an external catheter. This solves the problem of the existing technology, which uses sterile gauze to wrap the exposed part of the catheter and then uses medical tape to fix it to the patient's neck, which is prone to catheter displacement and suture breakage.
