[0047] The embodiments of the present utility model will be described in detail below with reference to the accompanying drawings.

[0048] Embodiment 1

[0049] A hemostatic device, as Figures 1 to 7 shown, includes a ring body 1, a balloon mechanism, a stamping assembly, a cooling medium circulation assembly 4, and a control box 5.

[0050] See Figures 1 to 3 , the ring body 1 includes two cylindrical flaps correspondingly divided along its axial direction, namely a first cylindrical flap 11 and a second cylindrical flap 12. The two sides of the first cylindrical flap 11 and the second cylindrical flap 12 are buckled with each other and can be separated or buckled into a ring according to requirements. Therefore, when in use, it is not necessary to insert the lower limb or upper limb into the ring body 1, which is more convenient. For the ring body 1, it can also be looped by using Velcro or other methods of the prior art, and the present application does not make specific limitations.

[0051] Furthermore, the ring body 1 has a variable section that conforms to the upper or lower limb of the human body, so as to better fit the lower or upper limb and achieve a better treatment effect. The ring body 1 is made of high-strength and antibacterial plastic that conforms to ergonomic design to ensure the durability and safety of the device.

[0052] The balloon mechanism includes multiple groups of balloon groups connected to the inner side of the ring body 1 and arranged along the height direction of the ring body 1. Each group of balloon groups has a plurality of balloons 2 arranged around the axis of the ring body 1. In this embodiment, there are 3 groups of balloon groups, and each group of balloon groups has 8 balloons 2, that is, 12 balloons 2 are provided on each of the two cylindrical flaps. The balloon 2 has an inflated state and a contracted state. When an inflation medium is introduced into the balloon 2, the balloon 2 is inflated under pressure. The balloon 2 is preferably made of TPE material.

[0053] The stamping assembly includes an expansion medium source (not shown in the figure) and an expansion medium channel 3. Among them, the expansion medium source is used to provide the expansion medium, and the expansion medium includes, but is not limited to, gases such as air or liquids such as water. In this embodiment, the expansion medium is air, and the expansion medium source is an air pump. The expansion medium channel 3 is used to connect the expansion medium source and the balloon 2, and there are multiple expansion medium channels 3 arranged in one-to-one correspondence with the balloon 2. A controllable valve (not shown in the figure) that can be opened or closed is provided on each expansion medium channel 3. When the controllable valve on the expansion medium channel 3 is opened, the balloon 2 corresponding to this expansion medium channel 3 is connected to the expansion medium source, and the balloon 2 can be inflated to expand; when the controllable valve on this expansion medium channel 3 is closed, the balloon 2 corresponding to this expansion medium channel 3 is not connected to the expansion medium source, and even if the expansion medium source is started, the balloon 2 cannot be inflated. Through the design of the expansion medium channel 3 and the controllable valve, the balloons 2 can expand or contract independently of each other. When hemostasis is performed, the corresponding balloon 2 can be controlled to expand according to the bleeding position, so as to accurately compress the bleeding position and prevent unnecessary compression of other areas from causing distal ischemia, and the secondary injury to the patient can be reduced. In addition, the balloons 2 can independently adjust the degree of expansion. For example, when one or more of the balloons 2 need a greater degree of expansion, only the controllable valve on the expansion medium channel 3 corresponding to this balloon 2 is opened, and the remaining controllable valves are closed, so as to perform a separate additional stamping on this balloon 2. In this way, the blood vessels can be uniformly and controllably compressed, and the hemostasis effect is better.

[0054] For the expansion medium channel 3, a part of it is located between the balloon mechanism and the ring body 1 and is arranged in an interlaced manner with each other, and the other part (not shown in the figure) is located outside the ring body 1 and converges in the connecting pipe 6. The connecting pipe 6 is preferably a corrugated pipe.

[0055] When worn, the ring body 1 is likely to wrap around the wearing area, causing sweating and stuffiness in the wrapped area, which is not conducive to blood coagulation and may even increase the risk of infection. Through the cooling medium circulation component 4, the wearing area is cooled, which can improve the hemostasis effect and the comfort of the patient. Specifically, the cooling medium circulation component 4 includes a cooling medium source, a cooling pipeline 44, a cooling medium channel, and a power mechanism. The cooling medium source is arranged between the balloon mechanism and the ring body 1, preferably a water tank 42 storing cooling water. The cooling pipeline 44 is arranged on the ring body 1 and is formed by connecting multiple U-shaped channels end to end. The balloons 2 are distributed in the grooves of the U-shaped channels. The cooling pipeline 44 is preferably an aluminum pipe, which is lighter. The cooling medium channel (not shown in the figure) is used to connect the cooling medium source and the cooling pipeline 44, and it includes a cooling medium inlet pipe and a cooling medium outlet pipe. The cooling medium inlet pipe and the cooling medium outlet pipe converge in the connecting pipe 6. In this embodiment, the cooling medium inlet pipe, the cooling medium outlet pipe, and the expansion medium channel 3 on the same barrel flap converge in the same connecting pipe 6. The power mechanism is used to input or output the cooling medium into or out of the cooling pipeline 44, and specifically it is a pump 41.

[0056] The control box 5 is arranged outside the ring body 1 and includes a housing 51, a controller 52, a display screen 53, a power supply 54, and a USB interface 57 arranged on the housing 51. A leather handle 55 is provided at the upper end of the housing 51, which is convenient for taking and using. Optionally, a mesh structure, such as a dust-proof net 56, can be used on the outside of the housing 51, which is lighter. The expansion medium source, the cooling medium source, and the power mechanism are arranged inside the housing 51 and are electrically connected to the controller 52 and can be controlled by the controller 52. The control valve is electrically connected to the controller 52 and can be controllably opened or closed. The control box 5 also includes a cooling fan 43 arranged on the housing 51 and used for dissipating heat from the cooling medium source. The cooling fan 43 is connected to the controller 52 and is controlled by the controller 52, and the wind force can be adjusted, so as to adjust the cooling temperature of the cooling medium. The housing 51 outside the cooling fan 43 is a dust-proof net 56, which has better heat dissipation performance.

[0057] The hemostasis device also includes a temperature sensing element (not shown in the figure) arranged on the cooling pipeline 44 or the cooling medium source. The temperature sensing element is electrically connected to the controller 52. The controller 52 collects and processes the temperature information of the temperature sensing element and controls the display screen 53 connected to it to display the temperature data. In addition, a pressure sensor (not shown in the figure) can be arranged in each balloon 2. The pressure sensor is electrically connected to the controller 52. The controller 52 collects and processes the pressure information of the pressure sensor and controls the display screen 53 connected to it to display the pressure data.

[0058] The above embodiments are only used to illustrate the technical concept and features of the present utility model. The purpose is to enable those skilled in the art to understand the content of the present utility model and implement it accordingly, and it should not be used to limit the protection scope of the present utility model. Any equivalent changes or modifications made according to the spirit of the present utility model should be covered within the protection scope of the present utility model.
