Then, the fixing plates 12 are inserted into the slots of the locking plates 13. Then, the locking plates 13 are released, so that the two sets of support springs 15 drive the two sets of locking plates 13 to reset, thereby locking the locking block 14 inside the locking plate 13 into the slots opened in the fixing plate 12, fixing the fixing plate 12 in the locking plate 13, which facilitates the installation of the remote control air pump 10.

[0022] Specifically, the fixation ring 4 is wrapped around the waist inside the patient's arm, and then the hemostatic headgear 1 is pulled by four sets of traction straps 5 to ensure that the hemostatic headgear 1 will not loosen. Then the fixation ring 4 is fixed to the patient's waist by the D-ring buckle 6.

[0023] Furthermore, the specific implementation of the control module includes the following steps: After receiving the start command from the human-machine interface module, the control module performs initialization detection on the connection status of the air supply module, the power supply module, and each press airbag 2. The control module controls the air supply module to start, inflating multiple sets of airbags 2 so that each airbag 2 fits against the corresponding area of ​​the head; The control module performs synchronous or independent pressure control on multiple sets of compression airbags 2 according to the preset control logic, in order to maintain the preset hemostasis state in each area; After the preset hemostasis state is achieved, the control module controls the air supply module to maintain the pressure state of each compression airbag 2. The control module outputs the current working status information through the human-computer interaction module.

[0024] Specifically, after receiving the start command from the human-machine interface module, the control module first performs initialization checks on the connection status of the air supply module, power supply module, and each pressure bladder. This includes checking the flow status of the air supply lines, the response of the solenoid valves, the stability of the pressure sensor readings, and the power supply voltage. The control module then reads the initial static pressure value from the pressure sensor. ,in Indicates the first Press each airbag to check if it is correctly connected to the headgear. If the pressure reading deviates from the threshold range... The control module issued an error message and stopped starting.

[0025] The control module controls the air supply module to start the micro air pump according to the initialization completion result, and fills the multiple groups of pressing air bags through the control of the electromagnetic valve until the air bags are attached to the corresponding areas of the head. When the pressure of the pressing air bag reaches the minimum attachment pressure, it indicates that the air bag has filled the gap and is in full contact with the head profile.

[0026] The control module controls the air bags according to the preset control logic, calculates the target pressure of each air bag using the partitioned closed-loop PID control algorithm, and the formula is as follows: is the control signal output to the air pump / electromagnetic valve of the first air bag, is the error between the target pressure and the actual pressure, is the preset hemostasis pressure of the first air bag, for example, , , , , , , , are the proportional, integral, and differential coefficients respectively, and the values are determined according to the field experiment debugging. The control module samples the pressure every milliseconds, updates the control signal , and drives the corresponding electromagnetic valve and air pump to adjust the pressure of the air bag.

[0027] After reaching the preset hemostasis pressure, the control module outputs the control signal and maintains the electromagnetic valve closed, and the pressing air bag maintains its pressure state. If the pressure of a certain air bag decreases by more than a threshold value in subsequent use, the control module restarts the inflation of the corresponding air bag to ensure that each region continuously maintains the preset hemostasis state.

[0028] The control module outputs the current working state information in real time through the human-computer interaction module, including the current pressure of each air bag , the system air supply state, whether the preset hemostasis pressure is reached, and the fault state. The display method can be LED, OLED screen or vibration feedback, ensuring that the user can monitor the system operation at any time.

[0029] The closed-loop control algorithm realizes accurate adjustment and maintenance of the pressure of the multi-partition pressing air bag, enables different regions of the head to stably reach the preset hemostasis pressure, provides real-time state feedback, and ensures that the individual can quickly and reliably complete the head hemostasis operation.

[0030] ​​​Further, the implementation of the gas supply module includes the following steps: Under the control of the control module, gas is supplied to multiple groups of pressing air bags 2; According to the instructions of the control module, different pressing air bags 2 are supplied with gas or stopped from being supplied with gas; After stopping the gas supply, the pressure state of the corresponding pressing air bag 2 is maintained.

[0031] Specifically, the gas supply module starts the micro air pump under the instructions of the control module to supply gas to multiple groups of pressing air bags. The gas flow of each air bag is independently adjusted by the control module through the electromagnetic valve. The output pressure of the air pump is ; determined by the closed-loop control formula: ; Wherein, is the real-time gas flow of the first air bag; is the preset hemostatic pressure of the first air bag; is the current pressure reading of the air bag; is the gas supply gain coefficient, which can be determined through experiments to ensure that the pressure rising speed is within the range of 5-10 mmHg / s, and to ensure that the air bag is smoothly attached to the head.

[0032] The control module samples every 100 milliseconds , and transmits the gas flow signal to the corresponding electromagnetic valve for adjustment, realizing independent or synchronous inflation of each air bag.

[0033] When a certain air bag reaches the preset hemostatic pressure , the control module sends a closing command to the gas supply module to stop the gas supply to the air bag, while keeping the electromagnetic valve closed to maintain the pressure of the air bag within the range of mmHg. If the actual pressure drops by more than the threshold value mmHg, the control module adjusts to supplement the air to the air bag until it returns to the preset pressure.

[0034] The gas supply module also dynamically allocates the air pump output according to the real-time instructions of the control module. When multiple air bags need to be pressurized at the same time, the gas flow is proportionally allocated to ensure that the total flow of the air pump does not exceed the maximum output , the formula is: ; Wherein, is the first pressure error of each airbag, is the total number of airbags.

[0035] The algorithm ensures that each airbag obtains air flow according to its needs, and realizes accurate pressurization of multiple airbags at the same time.

[0036] Through the above control logic, the air supply module can accurately supply or stop supplying air to each pressurizing airbag according to the instructions of the control module, and maintain the airbag pressure after stopping the air supply, so as to ensure the stability of the pressure state of each partition and meet the preset hemostasis requirement of the head multiple regions.

[0037] Further, the implementation of the pressure sensing module includes the following steps: Collecting the pressure state information of each pressurizing airbag 2; Sending the pressure state information to the control module; The control module identifies the current pressurizing airbag 2 pressure state of each pressurizing airbag 2 according to the pressure information.

[0038] Specifically, the pressure sensing module collects the internal pressure of each pressurizing airbag in real time through the micro pressure sensor embedded in each pressurizing airbag , wherein represents the airbag, The unit is mmHg. The sensor is connected to the control module through a flexible PCB, converts the analog signal into a digital signal, and performs filtering processing. The filtering algorithm uses exponential smoothing filtering, which is expressed as ; , wherein is the smoothed pressure value, is the smoothing coefficient, and the value range is 0-1, usually 0.3, which is used to reduce the influence of instantaneous vibration or artificial operation fluctuation.

[0039] The processed pressure signal is sent to the control module through the communication bus to form a pressure state data packet , wherein is the sampling timestamp, is the airbag number, which ensures that the control module can accurately correspond to the pressure of each airbag.

[0040] After the control module receives , according to the preset pressure threshold identify the current pressure state of each pressurizing airbag, and calculate the pressure error ; When , it is determined that the airbag pressure reaches the target state, is the allowable error, which is usually set to 1 mmHg; otherwise, it is determined that the airbag pressure is insufficient or too high.

[0041] With this pressure sensing module, the pressure state of each compression air bag can be collected and transmitted in real time, providing a closed-loop adjustment basis for the control module to ensure that the pressure of each head region is maintained within the preset hemostasis range.

[0042] Further, the implementation of the partitioned closed-loop control module includes the following steps: The control module compares the pressure state of each compression air bag 2 with the preset hemostasis state; When a certain compression air bag 2 does not reach the preset hemostasis state, the control module controls the gas supply module to adjust the pressure of the compression air bag 2; When a certain compression air bag 2 reaches the preset hemostasis state, the control module stops adjusting the pressure of the air bag and maintains the pressure state of the compression air bag 2.

[0043] Specifically, the partitioned closed-loop control module continuously collects the pressure of each compression air bag and the difference between its preset hemostasis pressure as the closed-loop control input, and calculates the pressure error: ; wherein is the air bag number, is the preset hemostasis pressure, for example, 40 mmHg in the frontal temporal region, 35 mmHg in the top occipital region, and 38 mmHg in the bilateral temporal occipital region, is the real-time pressure value collected by the sensor.

[0044] The control module uses a PID control algorithm to independently adjust the gas supply for each air bag, and calculates the control signal as follows: ; wherein is the output control signal of the electromagnetic valve or air pump of the gas supply module, with a unit of percentage opening, , , are the proportional, integral, and differential coefficients, respectively, and the values are determined through experiments to ensure that the air bag pressure rises smoothly and quickly to the target pressure. The integral term is used to eliminate steady-state error, and the differential term is used to suppress pressure overshoot. The control module updates every 100 milliseconds and outputs it to the corresponding air bag gas supply module.

[0045] When the pressure error satisfies the condition , wherein mmHg, the control module considers that the air bag has reached the preset hemostasis state, immediately stops the pressure adjustment of the air bag, closes the electromagnetic valve of the gas supply module, and maintains the current pressure state. If the pressure drops by more than the threshold value mmHg, the control module recalculates And start the air supply, to ensure the stability of the air bag pressure.

[0046] Through continuous sampling and closed-loop control calculation, the system can realize independent control of each partition under the condition of simultaneous inflation of multiple air bags, and each air bag pressure can be stably maintained in the preset hemostasis pressure range, avoiding overpressure or pressure leakage, and ensuring the hemostasis effect of different regions of the head.

[0047] Further, the implementation of the human-computer interaction module includes the following steps: Receive user start or control instructions and send them to the control module; According to the control of the control module, output the device running state information, including the pressure state of each pressing air bag 2 and the overall hemostasis state.

[0048] Specifically, the human-computer interaction module collects user instructions and outputs state information through physical keys, OLED display screens, LED indicator lights, and vibration motors. When the user presses the start or control key, the module converts the input signal ; Analog or level signal to digital instruction signal and sends it to the control module. The start instruction determination formula is ; Where is the start instruction sent to the control module, 1 indicates start, and 0 indicates invalid operation, is the key press duration threshold, for example, 2 seconds, used to avoid accidental touch.

[0049] The control module starts the air supply module and pressure closed-loop control according to The pressure state of each air bag ; And the overall hemostasis state . The overall hemostasis state is calculated by the error formula of the pressure of each air bag and the preset target pressure ; The overall hemostasis state is calculated by the error formula of the pressure of each air bag and the preset target pressure ; ; Where is the total number of air bags, is the pressure tolerance, for example, 1 mmHg, represents whether the i-th air bag reaches the target pressure.

[0050] The human-computer interaction module is configured to and The control module controls the display screen to output the pressure of each air bag ; and the real-time value of the target pressure ; The feedback algorithm is as follows ; wherein is a pressure deviation alarm threshold, for example, 5 mmHg, is the i-th air bag state feedback output.

[0051] The human-computer interaction module can complete user instruction collection, send control module execution operation, and real-time display of each air bag pressure state and overall hemostasis state, so that the operator can clearly master the hemostasis process and the working state of each air bag in extreme environment.

[0052] Further, the implementation of the wireless communication module includes the following steps: The control module generates working data related to the pressurized hemostasis process; The wireless communication module sends the working data to an external terminal device or a medical information system.

[0053] Specifically, the wireless communication module obtains the working data of the pressurized hemostasis process through the control module, including the real-time pressure , target pressure , closed-loop control error and overall hemostasis state of each pressurizing air bag. The module combines these data into a data packet , and the generation formula is ; wherein is the total number of air bags, is a timestamp in seconds, used to record the sampling time and ensure data order and historical tracking.

[0054] The wireless communication module sends the data packet to an external terminal device or a medical information system through Bluetooth 5.0 protocol or other short-distance wireless transmission methods, with a fixed refresh period Hz. Before sending, CRC check code The check generation formula for the data packet is ; Wherein represents a standard CRC16 check function, ensuring the integrity of the transmitted data. The receiving end verifies the correctness of the data through the check code, and sends a retransmission request if the verification fails.

[0055] During transmission, the control module can manage data packet priority through a queue mechanism. For airbags with pressure state changes exceeding the threshold, data packets are transmitted first to ensure real-time uploading of critical pressure states. Set the pressure change threshold mmHg, when , the data packet priority is set to high, ensuring that the medical terminal can obtain abnormal states in a timely manner.

[0056] Through the above operations, the wireless communication module can reliably transmit the real-time pressure state of each airbag, the overall hemostasis state, and the time information to the external terminal, realizing remote monitoring and data recording, and providing a reference for subsequent medical decision-making.

[0057] Further, the implementation of the emergency manual mode module includes the following steps: The control module enters emergency mode when it detects abnormalities in the gas supply module or the power module; The target pressurized airbag 2 is pressurized through the manual inflation structure to maintain the preset hemostasis state of the corresponding area.

[0058] Specifically, the emergency manual mode module automatically switches to emergency mode when the control module detects abnormalities in the gas supply module or the power module. The control module continuously collects the state of the gas supply module and the state of the power module to determine abnormal states, with the formula as follows: ; Wherein is the emergency mode flag bit, 1 indicating that the emergency mode is entered, and 0 indicating the normal mode, is the minimum voltage that the battery can supply, for example, 3.0V.

[0059] In emergency mode, the user can provide gas to the target pressurized airbag through the manual inflation structure. The manual inflation process is monitored by the airbag pressure feedback, and the control module calculates the current pressure error through the formula: ; Wherein preset hemostasis pressure for the ith airbag, for example, 40 mmHg for the frontotemporal region, 35 mmHg for the parietooccipital region, 38 mmHg for the bilateral temporaloccipital region, The pressure is collected in real time during manual inflation. The user gradually increases the airbag pressure by manual pump operation according to the displayed pressure or pressure indication feedback until the error ; mmHg, the control module determines that the airbag has reached the preset hemostasis state.

[0060] The manual inflation operation can maintain the pressure through the air valve locking structure. When the user stops operating, the air valve automatically closes, and the current pressure remains unchanged. If the pressure drops due to leakage by more than the threshold mmHg, the control module triggers a vibration or LED to prompt the user to continue manual air supply to ensure pressure stability.

[0061] The emergency manual mode module can still ensure that the pressure of each pressing airbag reaches the preset hemostasis state in the event of electronic air supply or power failure, ensuring that the hemostasis function of each region of the head is continuously effective.

[0062] Although embodiments of the present application have been shown and described, it is to be understood that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present application, the scope of which is defined by the appended claims and their equivalents.
