[0034] It should be noted that, in the absence of conflict, the features in the embodiments of the present invention may be combined with each other.

[0035] As mentioned in the background artery, an arterial compression hemostat is a medical device used to control bleeding in cases of trauma, surgery or other trauma. It compresses the artery at the wound site to block the blood flow in the artery to achieve the purpose of temporary hemostasis.

[0036] An arterial compression hemostat usually consists of a fixing tape, a pressure plate, a base and a spiral handle, wherein the fixing tape is made of a non-woven material coated with a rubber adhesive, and the pressure plate, the base and the spiral handle are made of a polycarbonate material.

[0037] The arterial compression hemostat in the prior art requires manual rotation of the spiral handle to drive the pressure plate to move, so as to apply pressure to the artery and block the blood flow in the artery. The operation is cumbersome, inefficient, and the pressure applied cannot be known.

[0038] In addition, mechanical arterial compression hemostat is effective for hemostasis of radial artery and axillary artery, but for hemostasis of femoral artery, due to the abundant muscle tissue around the femoral artery, it is easy to cause the pressure plate to shift, and the effect of arterial compression hemostat is poor.

[0039] In view of this, please refer to Figure 1-Figure 3 The arterial compression hemostat provided in the embodiment of the utility model can solve this problem, which will be described in detail below.

[0040] An embodiment of the utility model provides an arterial compression hemostat, which includes an air source 100, an air bag 200, a flexible plate 300, a pressure gauge base 400 and a compression piece 500. The air bag 200 is connected to the air source 100, the flexible plate 300 is equipped with the air bag 200, the pressure gauge base 400 is arranged on the flexible plate 300, the pressure gauge base 400 is used to install a pressure gauge (not shown in the figure), the air bag 200 is used to be connected to the pressure gauge, and the compression piece 500 is arranged on the side of the air bag 200 away from the flexible plate 300.

[0041] It is easy to understand that the arterial compression hemostat also includes a pressure gauge, which is installed on the pressure gauge base 400 .

[0042] The flexible plate 300 is fixed near the artery to be hemostatic (such as the femoral artery), and the airbag 200 is inflated through the air source 100. The airbag 200 expands and drives the compression member 500 to compress the artery, thereby blocking the blood flow in the artery to achieve the purpose of temporary hemostasis. This replaces the method of manually rotating the spiral handle to drive the pressure plate to move and achieve pressure on the artery in the prior art. The operation is simple and quick, and the hemostasis efficiency is improved.

[0043] At the same time, the pressure gauge base 400 can be installed with a pressure gauge to monitor the air pressure in the airbag 200 at any time, and further monitor the pressure of the compression member 500 on the artery in real time.

[0044] In this embodiment, in order to facilitate the installation of the pressure gauge, the pressure gauge base 400 is provided with a mounting circular hole 401 , and the pressure gauge is installed in the mounting circular hole 401 .

[0045] It is easy to understand that in order to facilitate the pressure gauge to measure the gas pressure in the airbag 200, a vent hole is provided at the bottom of the mounting circular hole 401, and an air flow hole 302 is provided in the middle of the flexible plate 300. The airbag 200, the air flow hole 302 and the vent hole are connected in sequence. In this way, the gas pressure in the airbag 200 can be transmitted to the pressure gauge in the mounting through hole, which is convenient for real-time monitoring of the pressure exerted by the compression member 500 on the artery.

[0046] In this embodiment, the arterial compression hemostat further includes an air tube 600 , and the air source 100 and the air bag 200 are connected via the air tube 600 , wherein one end of the air tube 600 is a threaded end, and the threaded end is threadedly connected to the air source 100 .

[0047] Among them, in this embodiment, the gas source 100 is a pressurized balloon, which is equivalent to a manual gas source. Of course, in other embodiments, the gas source 100 can also be an electric gas source, such as an electric air pump, which is more convenient and quick, and improves the inflation efficiency of the airbag 200.

[0048] The arterial compression hemostat also includes a three-way valve having an inlet and two outlets. One end of the trachea 600 away from the air source 100 is connected to the inlet of the three-way valve, and the airbag 200 is connected to one of the outlets of the three-way valve.

[0049] Another outlet of the three-way valve is connected to the outside atmosphere, which can prevent the airbag 200 from being inflated with excessive pressure. In the event of excessive inflation pressure, pressure can be released through another outlet of the three-way valve, that is, exhaust through the one-way valve in the three-way valve to reach a suitable pressure.

[0050] In order to facilitate the fixation of the arterial compression hemostat on the thigh, the arterial compression hemostat also includes a fixing belt 700, which is connected to the flexible plate 300. The fixing belt 700 can be a cloth belt. In this embodiment, the flexible plate 300 is a rectangular plate structure, and the flexible plate 300 is made of silicone, which is equivalent to a silicone belt. There are two fixing belts 700, and the two fixing belts 700 are respectively connected to the opposite sides of the flexible plate 300.

[0051] In order to facilitate the connection of the fixing belt 700, a rectangular through hole 301 is provided at both ends of the flexible plate 300. The two fixing belts 700 are respectively connected to the two rectangular through holes 301, and are tied to the thigh through the two fixing belts 700, thereby fixing the entire arterial compression hemostat to the thigh.

[0052] It should be noted that, in this embodiment, the compression piece 500 is a circular plate structure, one end surface of the compression piece 500 is used to compress the artery, and the other end surface of the compression piece 500 is connected to the airbag 200. When the airbag 200 is inflated, the compression piece 500 is away from the flexible plate 300, and when the airbag 200 is contracted, the compression piece 500 is close to the flexible plate 300.

[0053] Of course, in other embodiments, the shape of the pressing member 500 may also be a rectangular plate, and its shape is not limited here.

[0054] Because when tied to the thigh by two fixing belts 700, the compression piece 500 contacts the artery to be hemostatic, and the femoral artery at the compression piece 500 is pressurized by the expansion of the airbag 200. Compared with the method of using a spiral handle to drive the pressure plate to move to achieve pressure on the femoral artery, the compression piece 500 is not easy to shift. Therefore, the arterial compression hemostat provided in this embodiment has a better effect.

[0055] According to an arterial compression hemostat provided in this embodiment, the working principle of the arterial compression hemostat is as follows:

[0056] When performing femoral artery hemostasis, two fixing belts 700 are tied to the thigh so that the compression piece 500 on the flexible belt contacts the femoral artery. At this time, the entire arterial compression hemostat is firmly fixed to the thigh, and the air bag 200 is inflated through the air source 100 to expand the air bag 200 and drive the compression piece 500 to compress the femoral artery, thereby blocking the blood flow in the femoral artery and achieving the purpose of temporary hemostasis.

[0057] At the same time, the air pressure in the airbag 200 can be monitored at any time through a pressure gauge, and the pressure exerted by the compression member 500 on the artery can be monitored in real time.

[0058] To summarize, the arterial compression hemostat includes an air source 100, an airbag 200, a flexible plate 300, a pressure gauge base 400 and a compression piece 500. The airbag 200 is connected to the air source 100, the flexible plate 300 is equipped with the airbag 200, the pressure gauge base 400 is arranged on the flexible plate 300, the pressure gauge base 400 is used to install the pressure gauge, the airbag 200 is used to communicate with the pressure gauge, and the compression piece 500 is arranged on the side of the airbag 200 away from the flexible plate 300. The flexible plate 300 is fixed near the artery to be hemostatic, and the airbag 200 is inflated through the air source 100. The airbag 200 expands and drives the compression piece 500 to compress the artery, blocking the blood flow in the artery to achieve the purpose of temporary hemostasis.

[0059] It replaces the method of manually rotating the spiral handle to drive the pressure plate to move to apply pressure to the artery in the prior art. The operation is simple and quick, and the hemostasis efficiency is improved. At the same time, the pressure gauge base 400 can be installed with a pressure gauge to facilitate monitoring the air pressure in the airbag 200 at any time, and then the pressure of the compression piece 500 on the artery can be monitored in real time.

[0060] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed by the utility model should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
