The characteristics and technical content of the patent application related to the present model will be clearly presented in the following detailed description of the preferred embodiment with reference to the drawings.

Refer to FIG. 1, which is a new type of intelligent hemostatic device, which includes a tourniquet 1, a sensor chip 2, a sensor module 3, and an application unit 4.

The tourniquet 1 is detachably set on the limbs of a user. The sensor chip 2 is arranged on the tourniquet 1 to sense the connection state and send a sensing signal. Wherein, the sensor chip 2 is an RFID tag.

The tourniquet 1 has different materials. As shown in FIG. 2, the tourniquet 1 is an elastic rubber tube, and the sensing chip 2 is set in the tube body of the rubber tube. Here, the sensor chip 2 is a thin tube type RFID.

As shown in Figure 3, the tourniquet 1 includes a cloth belt 11, a first surface 12 contacting the user’s limbs, a second surface 13 opposite to the first surface 12, and a A first connecting piece 14 on one side 12, and a second connecting piece 15 on the second side 13, the first and second connecting pieces 14, 15 are used to fix the strap 11 to the limbs of the user Above, the first and second connecting members 14, 15 can be devil felt or connecting fasteners. The sensor chip 2 is arranged on the first surface 12 of the tourniquet 1, where the sensor chip 2 is a magnetic button type RFID.

The sensor module 3 includes a sensor 31 electrically connected to the sensor chip 2, a processor 32 electrically connected to the sensor 31, a box 33, and an indicator light electrically connected to the processor 32 34. The box 33 is used to install the sensor 31 and the processor 32, and the display light 34 is used to display the state of use of the tourniquet 1. Here, red and blue LEDs are set as the The light 34 is displayed, the red light means it has not been unlocked after the usage time, the blue light means it is in use. Preferably, the box body 33 is arranged on a hospital bed (not shown in the figure), and the display light 34 can also be arranged on the hospital bed. When the user lies on the hospital bed, the tourniquet 1 is bound to When the limbs, the sensor 31 located on the hospital bed emits radio waves to touch the sensor chip 2 to generate an electric current by electromagnetic induction, supply the sensor chip 2 to operate and send electromagnetic waves in response to the sensor 31.

The application program unit 4 is signal-connected to the processor 32, and includes an alarm 41 electrically connected to the processor 32 for receiving the control signal sent by the processor 32 and emitting a warning sound.

In actual implementation, the sensor 31 receives the sensing signal sent by the sensor chip 2 set on the tourniquet 1 and transmits it to the processor 32. The processor 32 makes a use state based on the sensing signal, and then The usage status is transmitted to the application unit 4 for display.

Among them, the processor 32 and the application unit 4 transmit signals in a wireless manner. The wireless transmission includes WiFi, Bluetooth, Zigbee, NB-IOT, LoRa, WiMAX, UWB, NB-IOT, 4G, 5G, etc.

Preferably, the medical staff can install the application program unit 4 on a human-machine interface device such as a desktop computer, a notebook computer, a tablet, a mobile phone, or a personal digital assistant (PDA). In this way, medical staff can learn the patient's use status in the human-machine interface device of the nursing station or the medical monitoring system.

When the sensor chip 2 sends the sensing signal, the processor 32 starts to calculate the use time of the tourniquet 1 according to the sensing signal. If the usage time of the tourniquet 1 exceeds a preset time, such as 30 minutes, the processor 32 sends a control signal To the application unit 4, to issue a warning sound that the tourniquet 1 has not been unwound after the usage time, and at the same time notify the nursing staff at the nursing station that the patient’s tourniquet 1 is abnormal in use, so as to achieve immediate monitoring of the tourniquet The use status of 1 improves the safety of patients.

In actual implementation, the state of use of the tourniquet 1 is unused as shown in Figure 5-1, which means that the tourniquet 1 is not used. When the tourniquet 1 starts to be used, it is in use as shown in Figure 5-2. When the tourniquet 1 starts to be used and exceeds the set time, as shown in Figure 5-3, it has been used for too long and a warning sound will sound.

In summary, the new type of intelligent hemostatic device and its use method, whereby the tourniquet 1, the sensor chip 2, the sensor module 3, and the application unit 4 are mutually set up, when the user lies on the Hospital bed, and when the tourniquet 1 is tied to the extremities, the sensor chip 2 sends the sensing signal, and the processor 32 calculates the use time of the tourniquet 1 based on the sensing signal, and then transmits the use status to the application The program unit 4 shows that the use status is transmitted to the medical staff’s mobile phone or medical monitoring system through remote transmission, providing medical staff with an e-style way to monitor the use status of the tourniquet 1 in real time. On the one hand, it can avoid forgetting to take it. Lowering the tourniquet 1 causes the occurrence of secondary injury of tissue injury, which improves the safety of the patient. On the other hand, it can also reduce the medical cost and waste caused by the negligence of medical personnel, so it can indeed achieve the purpose of new cost.
