Description

Technical Field

[0001] The utility model provides an inflatable radial artery tourniquet and relates to the technical field of tourniquets. Background Art

[0002] The radial artery is one of the terminal branches of the brachial artery and is slightly smaller than the ulnar artery. The radial artery is located shallowly between the lower end of the radius and the radial flexor carpi tendon, making it an ideal location for pulse palpation and puncture.

[0003] Existing tourniquets generally use physical pressure to block the flow of blood to stop bleeding, but this method cannot help blood coagulation. When the tourniquet is removed, some patients with slow blood coagulation are prone to bleeding. Therefore, the tourniquet needs to be used for a longer time to ensure that the blood coagulates and does not bleed. However, using a tourniquet for a long time can easily make people feel uncomfortable.

[0004] Therefore, it is necessary to provide an inflatable radial artery tourniquet that can assist blood coagulation. Utility Model Content

DETAILED DESCRIPTION

[0021] In order to make the purpose, technical solution and advantages of the utility model clearer, the utility model is further described in detail below in combination with specific implementation methods and with reference to the accompanying drawings. It should be understood that these descriptions are only exemplary and are not intended to limit the scope of the utility model. In addition, in the following description, the description of well-known structures and technologies is omitted to avoid unnecessary confusion of the concept of the utility model.

[0022] Example 1: An inflatable radial artery tourniquet, see Figure 1 , Figure 2 , Figure 3 and Figure 6 As shown, it includes a flexible belt 1, a restraining belt 101, a hemostatic airbag 2, an air outlet one-way valve 8 and an inflation component. The flexible belt 1 is fixedly connected to both sides of the hemostatic airbag 2 by riveting, and a restraining belt 101 is fixedly connected to one flexible belt 1 by sewing. An air outlet one-way valve 8 is installed on the side of the hemostatic airbag 2. The hemostatic airbag 2 is provided with an inflation component for inflating it, and also includes a console 17, a connecting block 18, a condensation hose 19 and a fixing belt 20. The connecting block 18 is installed on the flexible belt 1 by riveting, and the connecting block 18 is installed on the connecting block 18 by bolting. The connecting block 18 is connected to a condensation hose 19 for accelerating blood coagulation, and the condensation hose 19 is fixed to the side of the hemostatic airbag 2 that fits the patient's wound by the fixing belt 20, and the condensation hose 19 is electrically connected to the console 17.

[0023] See also Figure 2 and Figure 3As shown, the inflation component includes a compressed air bag 3, a mounting cabinet 4, a protrusion 401, a baffle 5, a torsion spring 6 and a ventilation pipe 7. The hemostatic air bag 2 is connected and communicated with the ventilation pipe 7. The end of the ventilation pipe 7 away from the hemostatic air bag 2 is connected and communicated with the mounting cabinet 4. The compressed air bag 3 is installed on the bottom of the mounting cabinet 4 by riveting. Two baffles 5 are rotatably arranged in the mounting cabinet 4. Two torsion springs 6 are fixedly connected between the two sides of the baffle 5 and the mounting cabinet 4 by welding. Two protrusions 401 for limiting the two baffles 5 are fixedly connected to both sides of the middle of the mounting cabinet 4.

[0024] When it is necessary to stop bleeding for the radial artery of the patient, firstly wrap the two flexible belts 1 around the patient's wrist, and make the hemostatic airbag 2 fit the wound, and insert one flexible belt 1 into the restraining belt 101 of the other flexible belt 1 for fixing, and then press the compressed airbag 3 to make the compressed airbag 3 inhale air and transmit it to the hemostatic airbag 2 through the ventilation tube 7. When the compressed airbag 3 transmits air to the ventilation tube 7, the airflow pushes the baffle 5 to rotate upward, and the torsion spring 6 is twisted and deformed by the force. When the compressed airbag 3 inhales air, the torsion spring 6 drives the baffle 5 to rotate in the opposite direction, and limits the baffle 5 by the protrusion 401. The baffle 5 can prevent the air in the hemostatic airbag 2 from flowing back into the compression airbag 3. The hemostatic airbag 2 expands after being inflated, so that the hemostatic airbag 2 presses the patient's wound and pressurizes the wound to block the blood circulation and stop bleeding. When the tourniquet needs to be removed, the air in the hemostatic airbag 2 can be discharged by opening the air outlet one-way valve 8 so that the tourniquet can be removed; when it is necessary to promote the clotting speed of the patient's wound, the condensation hose 19 is controlled by the control console 17 for refrigeration, so that the cold temperature is transmitted to the patient's wound through the hemostatic airbag 2, accelerating the coagulation of the blood, and at the same time alleviating the patient's pain and discomfort.

[0025] Example 2: Based on Example 1, refer to Figure 4 As shown, it also includes mounting blocks 9 fixedly connected to both sides of the two flexible bands 1 by riveting, and a wristband 10 is fixedly connected to the two mounting blocks 9 on the same side of the two flexible bands 1 by riveting, and a support ring 1001 is fixedly connected to one side of the wristband 10 by riveting, and a clamping rod 11 is slidably arranged on the support ring 1001, and an elastic member 12 is wound around the clamping rod 11, and a plurality of clamping slots 13 are opened on the other side of the wristband 10, and the clamping rod 11 is clamped with the clamping slot 13.

[0026] When the hemostatic airbag 2 expands, the hemostatic airbag 2 may shift the position of the wound. At this time, the two wristbands 10 are respectively wrapped around the front and back sides of the wrist wound, and one end of the wristband 10 is inserted into the support ring 1001 on the other side. The elastic member 12 pushes the clamping rod 11 to engage with the clamping slot 13, so that the wristband 10 is fixed on the patient's wrist, the positioning of the tourniquet is strengthened, and the displacement of the hemostatic airbag 2 is avoided. By engaging the clamping rod 11 with different clamping slots 13, the tightness of the clamping of the clamping slot 13 can be adjusted.

[0027] See also Figure 5 As shown, it also includes a mounting platform 14 installed on a flexible belt 1 on the side away from the console 17 by riveting, and a pressure gauge 15 for measuring the air pressure in the hemostatic airbag 2 is embedded on the mounting platform 14. The pressure gauge 15 is connected to the hemostatic airbag 2 and is connected to two pressure measuring tubes 16.

[0028] When it is necessary to measure the air pressure in the hemostatic airbag 2, by starting the pressure gauge 15, the air in the hemostatic airbag 2 is connected to the pressure gauge 15 through the pressure measuring tube 16, and the air pressure in the hemostatic airbag 2 can be displayed on the pressure gauge 15. The amount of air in the hemostatic airbag 2 can be adjusted according to the displayed air pressure value to avoid blood seepage due to too low air pressure, or discomfort to the patient due to too high air pressure.

[0029] See also Figure 2 and Figure 6 As shown, a protective plate 21 is rotatably provided on the pressure measuring device 15, and a protective sleeve 22 is sleeved on the compressed air bag 3. The protective plate 21 is used to protect the pressure measuring device 15 to prevent the pressure measuring device 15 from being damaged by collision; the protective sleeve 22 is used to protect the compressed air bag 3 to prevent the compressed air bag 3 from being damaged, thereby enhancing the practicality of the compressed air bag 3.
