[0018] In order to make the purpose, technical scheme and advantages of the embodiment of the utility model clearer, the technical scheme in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments. It should be understood that the specific embodiments described herein are only used to explain the utility model and are not used to limit the utility model. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0019] like Figure 1-3 As shown, an electric elastic tourniquet comprises: a machine base 1, a rotating drum 3 is arranged on one side of the machine base 1, a tourniquet 2 is wound around the rotating drum 3, the middle part of the tourniquet 2 is arched upward and extends out of the machine base 1 to form a hemostatic space, the rotating drum 3 is connected to the output end of the motor 4, a control panel is arranged on one side of the surface of the machine base 1, the control panel and the motor 4 are electrically connected to the controller 6, and the controller 6 is connected to a power supply.

[0020] In a preferred embodiment of the utility model, a protective frame 13 is arranged outside the hemostatic space formed by the tourniquet 2 , and the protective frame 13 is an inverted U-shaped structure, and the bottom of the inverted U-shaped structure is connected to the base 1 .

[0021] In a preferred embodiment of the present invention, a bracket 14 is provided at the bottom of the protection frame 13 , and the bottom of the bracket 14 is connected to the base 1 .

[0022] In a preferred embodiment of the utility model, the surface of the bracket 14 has a U-shaped support plate, and the two sides of the U-shaped support plate corresponding to the position of the tourniquet 2 have avoidance grooves for the tourniquet 2 to extend and retract.

[0023] In a preferred embodiment of the utility model, a torque sensor 5 is provided on the rotating drum 3 , and the torque sensor 5 is electrically connected to the controller 6 .

[0024] In a preferred embodiment of the present utility model, a display screen 8, a first button 9, a second button 10, a third button 11 and a fourth button 12 are provided on the control panel.

[0025] In a preferred embodiment of the present invention, the controller 6 is connected to a power source for daily use via a power line 7 .

[0026] The control system of the present application has an automatic tension compensation function system, which includes a torque sensor and a controller. The controller is preset with a control instruction of the motor. When the control instruction drives the motor to rotate, the torque sensor collects the torque data of the motor and feeds it back to the controller. The control unit compensates the set value in the control instruction according to the received torque data. When the motor torque is greater than or less than the set value, the torque is automatically compensated to keep the torque data within the set value range. The controller compensates the set value in the control instruction according to the received torque data in the following ways: when the torque data collected by the controller is lower than the lower threshold of the set value, the control instruction increases the torque output of the motor to compensate for the torque reaching the set value; when the torque data collected by the controller exceeds the upper threshold of the set value, the control instruction reduces the output of the motor torque to make the torque data reach the set value.

[0027] The controller collects torque data through a torque sensor, and a signal processing circuit can be connected in the middle. The signal processing circuit is used to denoise and amplify the feedback signal of the torque sensor and transmit it to the controller.

[0028] Instructions for use:

[0029] Before use, the medical staff first sets the motor torque value, and then resets the tourniquet to ensure that the patient's upper limb can be placed in the ring of the tourniquet 2.

[0030] When in use, the patient places the upper limb into the circular ring of the tourniquet 2, the medical staff confirms that it is properly placed, and presses the first button 9. After receiving the command, the controller 6 controls the motor 4 to rotate, and the rotating drum 3 rotates to tighten the tourniquet 2 and tie the patient's upper limb. The torque sensor 5 measures the output torque of the motor 4 in real time until the set value is reached, and the motor stops rotating and remains motionless.

[0031] If the medical staff finds that the tightening force of the tourniquet 2 is too small, they can press the third button 11 to increase the tension setting value, and the controller 6 controls the motor 4 to continue rotating and tightening until the setting value is reached.

[0032] If the medical staff finds that the tightening force of the tourniquet is too large, they can press the fourth button 12 to reduce the tension setting value, and the controller controls the motor 4 to rotate in the opposite direction and continuously relax until the setting value is reached.

[0033] When the tourniquet needs to be released, the second button 10 is pressed, and the controller 6 controls the motor 4 to rotate in the opposite direction until the tourniquet 2 rebounds to the initial position.
