Description

Blood vessel constant pressure hemostat

technical field

The utility model relates to a mechanical device, in particular to a medical device, that is, a hemostatic device for constant pressure of blood vessels.

Background technique

Hemodialysis (hemodialysis, HD) and other medical procedures that require blood drawing or blood transfusion through vascular puncture all need to stop bleeding from the pinhole of the blood vessel after the end. For needle holes with low blood flow pressure in blood vessels, bleeding can be stopped simply by pressing for a moment. For blood vessels with high blood pressure, the hemostasis process is more difficult and needs to last for a longer period of time, ranging from tens of minutes to several hours. During the pressing process, it is necessary to adjust the pressing force at any time according to the situation. If the pressure is too small, the bleeding cannot be stopped, and if the pressure is too high, it will cause blood blockage or thrombus formation, and even cause tissue necrosis. Once a blood clot develops, surgery is sometimes required, causing damage to the blood vessel. At present, the methods of hemostasis clinically adopted mainly include methods such as manual compression, sandbag compression, and tourniquet binding. Among them, manual pressing can adjust the pressure at any time, but it is difficult to persist for a long time. Sandbag hemostasis is to change the pressure by changing sandbags of different weights. The weight interval of sandbags is large, and stepless pressure adjustment cannot be realized. It is heavy or light, and it is difficult to choose a suitable sandbag. The tourniquet needs to be opened to adjust its tightness, and the strength index is more difficult to grasp. Therefore, in clinical practice, despite the care of medical staff, blood vessel damage accidents still occur from time to time. For patients on long-term dialysis, vascular access is invaluable, and damaging a vessel equates to a reduced chance of survival. Therefore, it is an urgent problem to be solved to ensure the circulation of the blood vessels and prevent the necrosis of the blood vessels while effectively stopping the bleeding.

Contents of the invention

The purpose of the utility model is to provide a blood vessel constant pressure hemostat which can not only prevent dialysis pinhole bleeding, but also avoid blood vessel blockage and damage.

The above-mentioned purpose is achieved by the following technical solutions: develop a blood vessel constant pressure hemostat, which is characterized in that: there is a rectangular fixing frame surrounded by hard rods, a pressure belt is arranged in the middle of one side rod, and The pressure belt is connected with the air bag through the trachea, and the pressure belt is connected with the manometer. When in use, pass the part that needs to be hemostatic through the fixed frame, then squeeze the inflatable bag to inflate the pressure belt, and observe the value of the pressure gauge at the same time, and perform the hemostasis operation of the pinhole with reference to the predetermined blood circulation bottom pressure value.

The rigid bar of the rectangular fixed frame includes a U-shaped frame and a splint with a through hole. The bars on both sides of the upper opening of the U-shaped frame are provided with threads, and are matched with the through holes on the splint. The nut fixes the upper limit position of the splint.

The air intake pipe of the pressurized belt is installed in the middle of the splint.

The compression band is a transparent balloon.

The bar at the bottom of the U-shaped frame is equipped with a supporting plate.

The pressure gauge is a mercury column pressure gauge.

The beneficial effects of the utility model are: the hemostatic pressure of the blood vessel can be determined with reference to the blood pressure value of the human body, which can not only stop bleeding, but also avoid blood stagnation and blockage in the blood vessel for a long time, prevent thrombosis and tissue necrosis, and the structure is simple, the cost is low, and the operation is easy. It is convenient and is expected to become a popular tool for hemostasis due to pinhole hemostasis in high-pressure blood vessels.

Detailed ways

The general idea of the utility model is to provide a device that can stop bleeding through pinholes in high-pressure blood vessels according to a certain pressure index. Introduce a kind of embodiment around this design below:

As can be seen from Fig. 1, this vascular constant-pressure hemostat has a component consisting of a fixed frame 1, a pressurizing belt 2, a trachea 3, an inflatable bag 4, a manometer 5 and the like. It can be seen in conjunction with Fig. 3 that the fixed frame 1 is a U-shaped frame 6 surrounded by hard rods and a splint 7 with a through hole. The through holes match, and the upper limit position of the splint 7 is fixed by the positioning nut 8 .

The air intake pipe of the pressurized belt 2 is installed in the middle part of the splint. There are many forms of the pressurizing belt 2, as long as it is an airtight and hollow pouch made of flexible material. The pressure band 2 is preferably as shown in Figure 4: it is a transparent balloon. In order to prevent oppressing people's limbs and increase comfort, the bar at the bottom of the U-shaped frame 6 adopts a wider supporting plate 9.

There are many kinds of products that the pressure gauge 5 can use, preferably the same mercury column pressure gauge as shown in Figure 1 and Figure 4 . Because this kind of pressure gauge can more conveniently refer to the blood pressure value of a person.

The hemostatic pressure value of this device is mainly determined with reference to the blood pressure value of the patient. Because when the pressure applied outside the blood vessel is greater than the high pressure value of the blood vessel, the blood in the blood vessel does not flow. Below the high pressure value, the blood vessels flow to varying degrees, until the low pressure value is completely open. According to the above rules, when hemostasis, the hemostatic pressure can be set within an appropriate range, so as to control the circulation of blood and achieve the purpose of bleeding and hemostasis. For this reason, the blood pressure value of the human body is known before the hemostasis operation, preferably the blood pressure value at the time of hemostasis.

The operation is as shown in Figure 5: the limb where the patient’s pinhole is located passes through the fixed frame 1. If the dialysis pinhole is on the arm, the arm can be passed through the frame, and the needle hole is covered with sterile cotton gauze, and then the The pressure belt 2 is pressed on the outside of the cotton yarn, the positioning nut 8 is screwed to determine the position of the clamping plate 7, and then the air bag 4 is squeezed by hand to inflate and pressurize the pressure belt 2 inside. At the beginning, the pressure can be higher and should be greater than the high pressure value of the blood vessel to achieve the purpose of hemostasis, and then slowly reduce the pressure to below the high pressure value and above the low pressure value, but the pressure without bleeding. In practice, when slight bleeding can be seen through the transparent pressurization belt 2, the pressure can be slightly increased. After a period of time, adjust it again according to the above method. The interval should be short first and then long, so as to avoid bleeding, ensure the circulation of blood vessels, and not damage the blood vessels.
