Description

Adjustable arteriovenous fistula tourniquet

Technical Field

The utility model relates to the technical field of medical devices, in particular to an adjustable arteriovenous fistula tourniquet.

Background technique

Arteriovenous fistula is one of the commonly used dialysis accesses for patients undergoing maintenance hemodialysis, with a usage rate of more than 80%. Arteriovenous fistula is regarded as the "lifeline" of patients undergoing hemodialysis. After each hemodialysis session, the nurse removes the arteriovenous fistula puncture needle and then uses a tourniquet, elastic bandage or finger pressure to stop bleeding. The current tourniquet bandage has the following problems:

1. Currently, tourniquets and elastic bandages are mainly fixed by bonding, which is troublesome to adjust. Sometimes the compression strength needs to be adjusted and re-bonded. During the adjustment process, the compression point may shift, resulting in complications such as bleeding at the puncture point and subcutaneous hematoma.

2. If the pressure is not well controlled, it will often lead to excessive pressure causing fistula dysfunction, while excessive pressure will cause bleeding at the puncture point.

3. The pressing time is determined by the doctor or the patient himself. Some elderly patients often forget the pressing time, causing fistula dysfunction.

Detailed ways

The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

Example 1

Please refer to Figure 1-2, an adjustable arteriovenous fistula tourniquet includes an elastic band body 1, and the elastic band body 1 is provided with an adhesive surface A2 and an adhesive surface B201 at the upper and lower ends, respectively. When the adhesive surface A2 and the adhesive surface B201 are bonded, they are sufficient to prevent loosening and falling off during use. A traction line 7 is provided inside one end of the elastic band body 1, and a fixer 8 is provided at both ends of the traction line 7, and the fixer 8 is fixed in the elastic band body 1 to ensure that the fixer 8 and the elastic band body 1 are firmly connected. A self-tightening knob 4 is provided between the two fixers 8, and the self-tightening knob 4 is connected to the traction line 7. Rotating and adjusting the self-tightening knob 4 will drive the traction line 7 to move, and the distance between the fixers 8 will change, and the fixer 8 will pull the elastic band body 1 to contract or expand. The elastic band body 1 can be adjusted to adjust the tightness and pressure.

The self-tightening knob 4 is provided with a timing module 3, and the timing module 3 can set the compression time. When the time is up, a sound or a color signal change is emitted to prompt the removal of the device. The inner side of the elastic band body 1 is provided with a compression protrusion 6, and the other side is provided with a compression point indicator 5, and the compression protrusion 6 is connected to the compression point indicator 5. The compression protrusion 6 is aimed at the patient's venous arterial fistula puncture point. The compression protrusion is made of a material that is harmless to the human body, and the compression protrusion and the compression point indicator are transparent, which is convenient for observing the position that needs compression.
