Usually in the application scenario of pelvic floor pressure detection, gas needs to be injected into the airbag and its pressure changes in the vagina are continuously monitored.

[0003] Among the existing gas control technologies, most devices can only realize airbag inflation control under pressure monitoring, but there is a lack of technology for automatic air extraction control or gas volume monitoring. If the airbag needs to be deflated, the current equipment mainly uses air valves to deflate during operation. If there is residual gas in the airbag that is not completely discharged, it may affect the inflation volume measurement and easily lead to inaccurate gas processing; and the current equipment only relies on pressure sensors to control the target inflation pressure value, and cannot accurately control the speed and volume of inflation and exhaust.

In comparison, the existing technology can only control the inflation of the airbag under pressure monitoring.

[0048] In the embodiment of the present application, the microcontroller may be an MCU. On the other hand, the microcontroller may be connected to the controller of the air pump and the controller of the air extraction pump, wherein the controller of the air extraction pump has a driving control function of the air extraction pump, and the controller of the air pump has a driving control function of the air pump, and the MCU may control the controller through a PWM control signal, and then control the air pump and the air extraction pump.

[0049] In an embodiment of the present application, as an optional implementation, the pelvic floor training system also includes a first air valve and a second air valve, a three-way pipe, an interface, and a first one-way valve, wherein the first air valve is connected to the three-way pipe, and the inflation pump is connected to the three-way pipe via the first one-way valve and the flow sensor; the interface is connected to the pressure sensor, the air bag, the second air valve and the vacuum pump, and then, when gas is injected into the interior of the air bag, the first air valve is closed and the second air valve is opened; when gas is extracted from the interior of the air bag, the first air valve is opened and the second air valve is closed.

[0050] This optional implementation can achieve switching between the exhaust process and the inflation process through the opening and closing combination of the first air valve and the second air valve.

[0051] For this optional embodiment, the first gas valve is as follows Figure 1 The air valve 1 shown, the second air valve as Figure 2 The air valve 2 is shown.

[0052] This optional implementation can prevent the gas from flowing back to the inflation pump through the first one-way valve, thereby ensuring that the gas passes through the flow sensor in a single direction.

[0055] Also, see Figure 2 , Figure 2 FIG. 1 is a flow chart of an inflation and degassing monitoring method for a pelvic floor training system provided by an embodiment of the present application. Figure 2 As shown, the inflation and degassing monitoring method comprises the following steps:

[0056] 101. Acquire a detection signal of a flow sensor, and determine a gas flow rate based on the detection signal of the flow sensor;

[0057] 102. The accumulated gas volume is calculated based on the gas flow rate and the sampling time interval.

[0058] The method of the embodiment of the present application obtains the detection signal of the flow sensor, and can determine the gas flow based on the detection signal of the flow sensor, so that the cumulative gas volume can be calculated based on the gas flow and the sampling time interval.

[0059] In the embodiment of the present application, as an optional implementation, the inflation and degassing monitoring method further includes the following steps:

[0060] During the inflation process, when the accumulated gas volume is greater than or equal to the preset gas volume threshold, the inflation pump is controlled to stop inflating the airbag;

[0061] or, during the inflation process, obtaining a detection signal of the pressure sensor and determining the internal pressure of the airbag based on the detection signal of the pressure sensor, and when the internal pressure of the airbag reaches a first preset pressure threshold, controlling the inflation pump to stop inflating the airbag;

[0062] And, after the inflation is completed, when the internal pressure of the airbag drops below a second preset pressure threshold, the inflation pump is controlled to re-inflate to maintain the internal pressure of the airbag.

[0063] This optional implementation can control the air pump to stop inflating the airbag when the accumulated gas volume is greater than or equal to a preset gas volume threshold. On the other hand, during the inflation process, the detection signal of the pressure sensor can be obtained and the internal pressure of the airbag can be determined based on the detection signal of the pressure sensor. When the internal pressure of the airbag reaches a first preset pressure threshold, the air pump can be controlled to stop inflating the airbag. After the inflation is completed, when the internal pressure of the airbag drops below a second preset pressure threshold, the air pump can be controlled to re-inflate to maintain the internal pressure of the airbag. It should be noted that the first preset pressure threshold and the second preset pressure threshold can be determined according to demand.

[0064] In the embodiment of the present application, as an optional implementation, the inflation and degassing monitoring method further includes the following steps:

[0065] During the air extraction process, when the internal pressure of the airbag is less than or equal to a third preset pressure threshold, the air extraction pump is controlled to stop extracting gas from the interior of the airbag.

[0066] This optional implementation can control the vacuum pump to stop extracting air from the interior of the airbag when the internal pressure of the airbag is less than or equal to a third preset pressure threshold during the vacuuming process.

[0067] In the embodiment of the present application, as an optional implementation, the inflation and degassing monitoring method further includes the following steps:

[0068] Calculate the flow rate change rate based on the gas flow rate during multiple sampling times;

[0069] The PWM control signal of the air pump or the PWM control signal of the air extraction pump is adjusted based on the flow rate change to adjust the inflation speed of the air pump or adjust the exhaust speed of the air extraction pump.

[0070] This optional implementation can calculate the flow change rate based on the gas flow within multiple sampling times, and then can adjust the PWM control signal of the inflation pump or the PWM control signal of the vacuum pump based on the flow change to adjust the inflation speed of the inflation pump or adjust the vacuum speed of the vacuum pump.

[0071] In the embodiment of the present application, as an optional implementation, the calculation formula corresponding to the cumulative gas volume calculated based on the gas flow rate and the sampling time interval is:

[0072]

[0073] Where V represents the cumulative gas volume, Qi represents the gas flow collected for the i-th time, and Δt represents the sampling time interval.

[0074] This optional implementation can accurately calculate the cumulative gas volume as described above.

[0075] In the embodiment of the present application, as an example, the system composition structure is: Figure 1 In the block diagram shown, the system of the embodiment of the present application includes: a microcontroller, a pressure sensor, a flow sensor, an air bag, an air valve 1, an air valve 2, a three-way pipe, a one-way valve, an air pump and an air pump.

[0076] Specifically, the microcontroller is used to control valve 1, valve 2, the inflation pump, and the exhaust pump, and receive data from the pressure sensor and the flow sensor. The pressure sensor is used to detect the pressure inside the airbag in real time, ensure that the pressure is within a safe range during the gas filling and discharging process, and continuously monitor the pressure changes caused by the squeezing of the airbag.

[0077] Specifically, the flow sensor is used to detect the flow rate and volume of gas during the inflation and exhaust process, and the speed and volume of inflation and exhaust are controlled by the electronic control system. Valve 1 and valve 2 are used to control the direction of gas flow, and the flow direction of gas is switched in combination with the three-way pipe. The one-way valve is used to prevent the gas from flowing in the reverse direction, ensuring that the gas passes through the flow sensor in a single direction.

[0078] Specifically, when the airbag needs to be inflated, the microcontroller closes valve 1, opens valve 2, and starts the inflation pump. The gas enters the airbag through the one-way valve and the flow sensor. The flow sensor detects the gas flow in real time to ensure that the inflation speed and gas volume meet the preset requirements.

[0079] Specifically, the pressure sensor can continuously monitor the pressure value in the airbag, and automatically stop inflating when the set pressure value (e.g., 50 mmHg) is reached. At the same time, when the pressure exceeds the limit value (e.g., 150 mmHg), the air valve will open to prevent the airbag from being over-pressurized.

[0080] Specifically, the gas flow sensor measures the amount of gas flowing per unit time, i.e., the instantaneous flow rate. By combining the flow data with time, the gas volume can be calculated. In specific implementation, the following formula is used:

[0081] Where: V is the cumulative gas volume, Qi is the gas flow collected for the i-th time, and Δt is the sampling time interval.

[0082] Through the above method, the system can continuously monitor the cumulative inflation volume and automatically stop inflation when the set volume value (for example, 10 mL) is reached.

[0083] Specifically, the system calculates and accumulates the real-time data of the flow sensor according to the gas volume target value set by the user, thereby accurately controlling the total amount of gas charged or withdrawn. When the accumulated gas volume reaches the preset value, the system automatically stops charging.

[0084] Specifically, the algorithm can also be used to dynamically adjust the inflation or extraction speed. In some applications, the microcontroller can appropriately adjust the PWM control signal of the inflation pump or the extraction pump according to the changing trend of the gas flow (e.g., the flow rate change rate) to achieve precise gas volume control and avoid overshoot or under-extraction.

[0085] Specifically, when the airbag needs to be evacuated to shrink it, the microcontroller opens valve 1, closes valve 2, and starts the air pump. The gas is pumped out of the airbag through the three-way pipe and the flow sensor, and the flow sensor can also detect the gas flow and volume during the pumping process. Similar to the inflation process, the system can accurately control the pumping speed and amount.

[0086] Specifically, when the gas circuit needs to be completely deflated to reach atmospheric pressure balance, the microcontroller opens gas valve 1 and gas valve 2, and the gas in the system is completely released through the gas circuit.

[0087] The innovation of this example is that through reasonable gas circuit design, only one flow sensor is needed to detect the gas flow of inflation and exhaust at the same time. Through the cooperation of the three-way pipe and the air valve, the gas flow and volume detection of inflation and exhaust can be realized, while the airbag pressure is monitored and accurate data feedback is provided. Compared with the prior art, the embodiment of the present application greatly reduces the number of sensors used, reduces the system cost, improves the overall reliability and efficiency of the system, and can accurately calculate indicators such as pelvic floor fullness and tolerance.
