Description
Technical Field
The utility model relates to the technical field of medical equipment, concretely relates to arteriovenous internal fistula haemostat with adjustable dynamics.
Background
An optimal evidence analysis about arteriovenous internal fistula maintenance summarizes and prompts that a compression method, time and force are all important for the maintenance of the internal fistula from the aspects of a puncture method, a compression method, an evaluation method and the like. Common general knowledge of vascular access experts for hemodialysis in China (version 2) recommends that pressing blood vessels is preferable to touch tremor of blood vessels, but actual pressing strength still cannot be clear to a specific value and that the tremor of internal fistulas is inconvenient to touch when pressed by one hand. The compression hemostasis after puncture is carried out by manual finger pressing, or the better hemostasis after puncture is achieved by the combination of elastic bandage and gauze pressing, which is a commonly used clinical hemostasis method, but the compression method is not easy to implement force adjustment, and the old people are easy to rely on other people or elastic bandage for compression, and the compression force and time are not controllable.
The gauze is fixed on the traditional medical adhesive plaster for many times, and the finger presses the bleeding point to stop bleeding, so that the pressing pressure is too high or too low, and the bleeding is not stopped in place. The elastic tourniquet is tied in a ring to stop bleeding, the tourniquet is loosened for 1 time every 10 minutes or so until no blood seeps at the needle eye, and then the tourniquet is taken down. The patient needs to operate the tourniquet by one hand to relax, the pressing position is easy to shift in the process, the pressed part oozes blood or is pressed by the tourniquet, and the pressing time is prolonged; people who have inconvenience in single-hand operation need others to assist.
The application number is CN108577925A elasticity pulse pressing belt compresses the gauze piece pressurization puncture point hemostasis, monitors the pressing time through device timer and microcontroller, regularly releases. The pressure is applied within a fixed time, the force is fixed and cannot be adjusted, and the pressure is too large or too small.
The application number is CN215778386U spiral hemostasis by compression device, and rotatory hob drives the piece of oppressing and reciprocates and realize the hemostasis by compression of puncture point. The adjusting belt is pasted on the fixing plate to fix the hemostat on the arm, and the pressure pressing process is adopted to adjust the hemostat with the risk of disconnection. The screw rod is fixedly connected with the pressing block, and the screw rod rotates to generate horizontal knob force to act on the pressing contact surface to rub the skin around the puncture point. There is a risk of skin damage.
The arteriovenous internal fistula compression hemostat developed by the scheme can realize the functions of dynamically adjusting internal fistula compression hemostasis force, recording compression time and protecting skin in a compression area in a fixed compression direction. Is applied to hemostasis by pressing after clinical hemodialysis puncture to solve the problems that the hemostasis strength of a puncture point can not be adjusted, compression displacement, vascular access maintenance and the like after dialysis at the present stage.
