The upper airbag and the lower airbag are respectively placed inside the two ends of the support frame. Connect to both ends of the support frame. This radial artery hemostat is inflated and pressurized by the airbag to complete the bandage without blood leakage at the puncture site. The pressure of the airbag is completely borne by the C-shaped stent, which overcomes the hemostatic pressure of other hemostatic devices and acts on the back of the wrist to affect venous return. disadvantages.

Description

radial artery hemostat

technical field

The utility model relates to an operation hemostatic device, which belongs to the technical field of medical instruments.

Background technique

With the improvement of living conditions and the change of people's working style, the incidence of coronary heart disease is increasing year by year. Angiography and stent placement through the radial artery have become one of the most important methods for the diagnosis and treatment of coronary heart disease. Good venous return after surgery can promote wound healing and reduce the discomfort of patients. However, the traditional gauze roll pressure hemostasis method seriously hinders the venous return of the palm. Therefore, hemostasis and bandaging after radial artery puncture has always been a clinical problem that needs to be solved urgently. problem. In order to solve this problem, technicians have designed a variety of devices for hemostasis after radial artery surgery. However, all kinds of radial artery hemostats currently on the market have more or less disadvantages affecting the venous return of the palm. The side hand is swollen, numb, and even painful, which does not achieve the desired effect.

Contents of the invention

The technical problem to be solved by the utility model is to provide a radial artery hemostat that can overcome the disadvantages of gauze roll bandaging to stop bleeding and other hemostatic devices affecting palm venous return.

The technical scheme that solves the above-mentioned technical problem is:

A radial artery hemostat, comprising an upper airbag, a lower airbag, a support frame, and a fixing belt, the support frame is C-shaped, the upper airbag and the lower airbag are respectively placed inside the two ends of the support frame, and the upper and lower airbags are connected to the outer The inflatable device is connected, and the fixing belt is connected with the two ends of the supporting frame.

In the aforementioned radial artery hemostat, one end of the fixing band is connected to one end of the support frame, and the other end is detachably connected to the other end of the support frame after wrapping around the wrist.

The above-mentioned radial artery hemostat also has a slidable support pad, which is made of soft materials such as sponge or foam plastic, and is placed on the inside of the fixing band on the ulna side of the wrist.

In the aforementioned radial artery hemostat, the upper and lower airbags are connected to the inflation device outside the support frame through a three-way connection tube.

In the aforementioned radial artery hemostat, the detachable connection between the support frame and one end of the fixing belt is a Velcro connection.

When the utility model is in use, the air bag is inflated and pressurized to complete the bandage without blood leakage at the puncture site, and the pressure of the air bag is completely borne by the support, which overcomes the drawback of other hemostatic devices that the hemostatic pressure acts on the back of the wrist at the same time and affects the venous return.

Description of drawings

Fig. 1 is a structural schematic diagram of an embodiment of the utility model.

The markings in the figure are as follows: upper airbag 1, lower airbag 2, support frame 3, fixing belt 4, Velcro 5, tee connecting pipe 6, slidable support pad 7, inflation device 8

Detailed ways

As can be seen from FIG. 1 , the device includes an upper airbag 1 , a lower airbag 2 , a support frame 3 , a fixing belt 4 , a slidable support pad 7 , a tee connecting pipe 6 , and an inflation device 8 . When used after the operation, the C-shaped support frame 3 is placed on the wrist of the operated side, the upper air bag 1 is accurately aligned with the puncture site of the palmar radial artery, and the lower air bag 2 is placed on the symmetrical part of the back of the hand. The support frame 3 is connected with the fixing belt 4, and the fixing belt 4 surrounds the wrist, and the fixing belt 4 and the support frame 3 are pasted and fixed by Velcro 5 outside the lower end of the support frame 3. Elastic fixing belts can also be selected, and its two ends are respectively fixed on the two ends of the support frame 3 . A slidable support pad 7 is placed on the inner side of the fixing belt 4 close to the wrist ulna. Slidable support pad 7 is made of soft materials such as sponge, foamed plastics. The slidable support pad 7 should be adjusted to a suitable position on the ulna side of the wrist before the fixed position of the fixing belt 4 and the support frame 3 is fixed. After the fixing belt 4 is fixed, the upper and lower airbags are inflated by the external inflation device 8 through the three-way connecting pipe 6 . The inflation device 8 can be a pressurized rubber ball, or a pressure-sensing airbag, and the interface of the pressure-sensing airbag is connected with a pressure pump to inflate the airbag. Pay attention to observe the bleeding at the puncture site when inflating, and complete the operation with no active bleeding at the puncture site as the inflation standard.

The C-shaped support frame 3 of this radial artery hemostasis device is formed at one time by using plastic molds, and the external reinforcement ribs make the pressure of the airbag completely bear by the support frame 3, which overcomes the hemostatic pressure of other hemostatic devices that simultaneously acts on the back of the wrist and affects the veins. The disadvantage of reflux reduces the discomfort of patients after surgery. Support frame 3 is also made as " U " shape or " [ " shape.
