The invention is described in detail below with reference to the figures and specific embodiments. The present embodiment is implemented on the premise of the technical solution of the present invention, and a detailed implementation manner and a specific operation process are given, but the scope of the present invention is not limited to the following embodiments.
The embodiment provides a feedback type automatic hemostasis system, which comprises a compression device, a pressure detection device, a timing device, an alarm device, a humidity sensing device, a temperature sensing device and a control device, wherein the control device plays a role of central control and is connected with all other devices to control the operation of the other devices, as shown in figure 1.
The compression device is externally fixed, the compression device is internally connected with the hemostasis plate through threads, the internal threads can be controlled by the motor, and the blood plate is prevented from being pressed down and lifted in a rotating mode through the motor control threads, so that the pressure control during hemostasis is more convenient.
The pressure detection device detects the pressure at the hemostasis part, and for safety, the pressure detection is needed to be carried out on the hemostasis part before hemostasis, and hemostasis can be carried out only when the pressure meets the standard. Meanwhile, the pressure detection device also detects the pressure at the hemostasis position in real time in the hemostasis process, and feeds back the pressure to the control device according to the difference between the pressure and the rated hemostasis pressure so as to adjust the pressure applied by the compression device, and the hemostasis pressure is adjusted in a feedback mode.
The timing device is a timer, and can feed back time to the control device to judge whether the hemostasis operation duration meets the rated hemostasis time, wherein the rated hemostasis time is not a fixed value and is determined by a hemostasis part, and the specific part and time are determined according to the following hemostasis time schedules of different parts:
| hemostasis area | Rated hemostasis time |
| Vein of upper limb | 5 minutes |
| Vein of lower limb | 10 minutes |
| Finger tip | 3 minutes |
| Artery | 30 minutes |
Before hemostasis is started, if the pressure at the hemostasis part is not satisfactory, the alarm device is started so as to process relevant conditions at the first time.
The humidity sensing device detects whether liquid exists at the hemostasis position after the hemostasis position reaches the rated hemostasis time, wherein the humidity sensing device comprises a contact type probe, and the sensing probe is isolated when the humidity sensing device does not contact the liquid, so that an electric signal is not generated; when the liquid is contacted, the sensing probe is conducted to generate an electric signal. The temperature sensing device comprises a thermistor, generates current according to the change of the liquid temperature, feeds the current back to the control device to calculate the liquid temperature, and compares the liquid temperature with the human body temperature threshold value to determine whether hemostasis is successful. The humidity sensing device and the temperature sensing device can further detect whether bleeding still exists in the hemostasis part after the hemostasis action is finished so as to judge whether hemostasis is successful, and therefore the reliability of hemostasis is guaranteed.
The control device comprises a processor and a memory, wherein the processor calls a program in the memory to execute the following steps:

and if the pressure of the bleeding part is greater than the first pressure threshold value, starting the alarm device and stopping hemostasis.
If the pressure of the bleeding part is smaller than the first pressure threshold, the compression device is started to stop bleeding on the bleeding part, the compression device is fixed outside, the inside of the compression device is connected with the hemostasis plate through threads, the hemostasis is performed by compression in a mode of rotating the internal threads under the control of a motor, the motor rotates in the positive direction, the hemostasis plate presses downwards, and the pressure is increased; the motor rotates in the reverse direction, and the pressure is reduced. The pressure detection device monitors whether the pressure at the hemostasis compression position meets the rated hemostasis pressure P0 in real time in the hemostasis process, and stops rotating and does not increase the pressure any more if P0-delta P < ═ P0+ delta P, wherein delta P is a rated error. Considering the influence of external factors, the pressing unit and the pressure sensing unit always work, and if P is greater than P0+ delta P, the pressing unit and the pressure sensing unit rotate reversely to reduce pressure; if P < P0- Δ P, the rotation is positive and the pressure is increased.

If the processor does not receive the electric signal, judging that the hemostasis is successful; if the processor receives the electric signal, the temperature sensing device is started and receives the electric signal of the temperature sensing device to calculate the liquid temperature, the temperature sensing device comprises a thermistor, the resistance value of the thermistor changes according to the difference of the temperature, so that the output current changes, and the processor calculates according to the received current and the following formula:
T＝T1-273.15
Rt＝U/I
T1＝1/(ln(Rt/R)/B+1/T2)
in the formula, for convenience of calculation, T1 and T2 are both temperatures in thermodynamic units, and T represents the temperature in degrees celsius corresponding to T1, i.e., 273.15 is subtracted from the temperature in thermodynamic units; rt represents the resistance value of the thermistor in the temperature sensing device at the measured temperature T1, U represents the applied voltage, I represents the current magnitude in the processor, R represents the nominal resistance value of the thermistor in the temperature sensing device at the normal temperature T2, and B represents the thermosensitive parameter. The calculated result has an error correction of 0.5 degrees celsius.
When the calculated liquid temperature is higher than the human body temperature threshold value, judging that the hemostasis fails; when the temperature of the liquid is not higher than the human body temperature threshold value, the hemostasis is judged to be successful, and the human body temperature threshold value is set to be 30 ℃.
If the hemostasis is judged to be failed, the system continues to operate and continues to finish the hemostasis operation; if the hemostasis is successful, the compression device is controlled to rotate reversely until the pressure detection device detects that the pressure at the front end is 0, and then the system stops working and is locked.
