Description

A hemostatic bracelet for arteriovenous fistula with adjustable timing and pressure

technical field

The utility model relates to the technical field of medical instruments, in particular to a hemostatic bracelet for arteriovenous fistula with adjustable timing and pressure.

Background technique

Hemodialysis is a kind of blood purification technology, which is mainly used for the treatment of patients with end-stage renal disease. Most patients on hemodialysis are treated for long-term maintenance, about 2-3 times a week. In our country, more than 95% of patients use arteriovenous fistula as a lifeline. The arteriovenous fistula is basically located on the forearm or upper arm of the patient. The artery near the wrist of the forearm and the adjacent vein are sutured together so that arterial blood flows in the vein after the anastomosis, forming an arteriovenous fistula. Although the blood in the arteriovenous fistula can provide sufficient protection for hemodialysis, since the vein is arterialized, its pressure will also increase, so it is particularly important to stop bleeding at the puncture point after each dialysis. At present, the commonly used methods in clinical practice are elastic band compression or artificial compression. These two methods mainly have the following defects: 1. The pressure value is completely dependent on the subjective judgment of the patient or the experience of the nurse to judge the tightness; 3. New patients have poor compliance with the tightness of the tourniquet, or do not know when to adjust the tightness, or even forget to remove the tourniquet, resulting in shortened life span of the internal fistula.

Utility model content

The purpose of the utility model is to overcome the deficiencies of the prior art, and provide a hemostatic bracelet for arteriovenous fistula with timing effect and adjustable pressure.

In order to achieve the above purpose, the utility model provides a hemostatic bracelet for arteriovenous fistula with adjustable timing and pressure, which includes a belt body, a base plate and a pressing piece, one end of the belt body is provided with a toothed fastener, and the other One end is provided with a toothed slot matching the toothed fastener, the base plate is located in the middle of the belt body,

The bottom surface of the belt body is concave arc-shaped;

A through hole is set on the base plate, and an internal thread is arranged in the through hole, a timer and a sounding device are installed on the base plate, and the timer and the sounding device are connected;

The pressing piece is in the shape of a bolt, the outer surface of the lower part of the pressing piece is provided with external threads, and the pressing piece is threadedly connected with the through hole of the substrate;

A group of cushioning pads are symmetrically provided on the bottom surface of the belt body.

Preferably, an arteriovenous fistula blood flow probe is installed on the bottom surface of the substrate, and a display screen is installed on the top surface, and the arteriovenous fistula blood flow probe is connected to the display screen.

Preferably, the bottom surface of the pressing member is provided with a pressing layer;

The bottom surface of the buffer pad has textures.

The beneficial effects of the utility model are:

1. Using the bracelet structure, the pressure can be changed step by step or decrease. The size can also be adjusted according to the thickness of the arms of different patients, avoiding the problem that the pressure value of the elastic band cannot be accurately calculated;

2. Place cushion pads 5 made of silica gel with a width of about 1.5 cm on the left and right sides of the oppression of the puncture point. In order to prevent the cushion pad 5 from slipping due to the low friction of the silica gel material, threads are provided on the bottom surface of the cushion pad 5. Shaped texture to increase friction. The silicone material of the buffer pad can not only make the patient feel comfortable but also protect the skin around the puncture point to a great extent. Gauze can be placed between the two buffer pads to further protect the skin;

3. A timing device is added, and the timer rings once every 20 minutes from the end of hemodialysis when the hemostatic ring is used. After three times, music was played to prompt the patient to take off the bracelet. Prevent the patient from forgetting to remove the tourniquet. The problem of shortening the life of internal fistula due to excessive compression time. At the same time, the timing device is like a watch, and its appearance is more beautiful than that of a tourniquet;

4. The arteriovenous fistula blood flow probe monitors the wearer's instantaneous blood flow in real time, and displays the specific waveform and value on the display screen, which helps medical staff better understand the patency of the patient's arteriovenous fistula ;

5. The bracelet is made of stainless steel and will not weaken the aging pressure of long-term use. The tail of one end of the bracelet is designed as a limit mechanism with a concave groove with a buckle, and the end of the other end is a tooth-shaped short plate. During clinical use, the operator buckles the tooth-shaped short plate with the finger to the position of the downward concave groove, so that it is basically consistent with the thickness of the patient's wrist. The card slots snap together and the length of the bracelet is fixed. It is suitable for use by various patients, and has the advantages of low cost, simple structure, easy disinfection and long-term use without replacement.
