Description

Technical Field

[0001] The utility model belongs to the technical field of medical nursing equipment, in particular to a hemodialysis neck vein indwelling catheter fixing belt. Background Art

[0002] Hemodialysis is a type of blood purification technology that uses the principle of a semipermeable membrane to remove various harmful substances, excess metabolic waste and excess electrolytes from the body through diffusion and convection, thereby purifying the blood and correcting electrolyte and acid-base balance. Establishing and maintaining a good vascular access is the primary condition to ensure the smooth progress of hemodialysis. Vascular access is the lifeline of patients undergoing long-term maintenance hemodialysis. When doctors establish blood access for patients, they will use a central venous catheter as a treatment method, among which a jugular vein catheter is one of the most commonly used treatment methods.

[0003] The traditional method of fixing the hemodialysis cervical venous catheter is to wrap the intravenous catheter with sterile gauze and fix the gauze to the patient's skin with medical tape. This fixation method has many defects. First, the medical tape sticks to the patient's skin, which is easy to cause skin allergies, itching and pain in the patient; second, the medical tape is not firmly adhered, which is easy to cause the catheter to fall off and bend, which is not conducive to catheter fixation. Utility Model Content

[0004] In view of the above problems, the utility model provides a hemodialysis jugular vein indwelling catheter fixing belt.

[0005] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a hemodialysis neck vein indwelling catheter fixing belt, including a neck strap, a catheter fixing assembly is arranged on the surface of the neck strap, and the catheter fixing assembly includes a fixing block, and the fixing block is fixedly arranged on the surface of the neck strap, and a groove is opened on the fixing block, and two restraining belts are arranged on the fixing block, and the other ends of the two restraining belts span the groove and are provided with a connecting block, and two indwelling catheter tail end fixing bags are arranged on the surface of the neck strap on both sides of the catheter fixing assembly.

[0006] Preferably, the bottom end surfaces of the two connecting blocks are both provided with an adhesive layer, and the adhesive layer is bonded to the fixing block.

[0007] Preferably, adhesive tape is provided on the inner surfaces of the two restraining belts.

[0008] Preferably, the fixing block is located in the groove and a space cotton layer is fixedly arranged therein, and the space cotton layer is adapted to the groove.

[0009] Preferably, the two indwelling catheter tail end fixing bags are both provided with seals, and the two indwelling catheter tail end fixing bags are centrally symmetrical about the middle position of the neck strap.

[0010] Preferably, the neck strap is made of modal material, and the two restraint straps are made of cotton material.

[0011] Preferably, a first Velcro is provided at one end of the neck strap, and a second Velcro matched with the first Velcro is provided at the other end of the neck strap.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] 1. The neck strap can be wrapped around the patient's neck by tightly bonding the first Velcro and the second Velcro. When used in hemodialysis, it can fix the catheter, reduce the use of tape, and avoid skin infections caused by tape allergies. The neck strap is comfortable, soft, and elastic, and has no irritation to the patient's skin, avoiding the pain caused by the use of medical tape on the patient's skin.

[0014] 2. By placing the indwelling catheter in the groove on the fixing block, and then placing the other ends of the two restraints across the indwelling catheter, the adhesive tapes on the inner surfaces of the two restraints are closely attached to the indwelling catheter, and the adhesive layers on the bottom end surfaces of the two connecting blocks are bonded to the fixing block, the indwelling catheter is bundled with the two restraints, and the indwelling catheter is restricted by the adhesive tape, which can effectively prevent the indwelling catheter from falling off or bending.
