Embodiment 1

[0063] In the air blowing mode and the voltage stabilization mode, the air pressure value is obtained every 5ms, the latest 10 air pressure values ​​are sorted by size, the largest 3 values ​​and the smallest 3 values ​​are discarded, and the remaining 4 air pressure values ​​are calculated. Average value to get the filtered air pressure value.

[0064] In the constant voltage mode, when the filter air pressure value is less than 0.6mmHg, it switches to the blowing mode.

[0065] In the blowing mode, when the difference between the two adjacent filter air pressure values ​​is greater than 0.03mmHg, it switches to the voltage stabilization mode.

[0066] Different types of air pressure sensors 7 have different sensitivities. The maximum and minimum values ​​of the most recent air pressure values ​​are removed, and then the average value is calculated, which can avoid the fluctuation caused by the air pressure sensor 7 itself to affect the judgment of switching the working mode....

Embodiment 2

[0068] In blowing mode and constant voltage mode, the air pressure value is obtained every 8ms.

[0069] In the constant voltage mode, when the air pressure value is less than 0.4mmHg, it switches to the blowing mode.

[0070] In the air blowing mode, when the difference between the two adjacent air pressure values ​​is greater than 0.05mmHg, or when the air pressure value is greater than or equal to the third preset value, the mode is switched to the voltage stabilization mode. The third preset value is set to the maximum value in the air blowing mode. After the flow is output, add 5mmHg to the air pressure in the pipeline. If the air pressure value detected in the blowing mode is greater than the air pressure value at the maximum flow output, it proves that there is resistance in the pipeline. If it is 5mmHg higher than the air pressure value at the maximum flow output, it proves that the resistance source is not an ordinary obstacle blocking the transmission. Before the ex...

Embodiment 3

[0072] In blowing mode and constant voltage mode, the air pressure value is obtained every 10ms.

[0073] In the constant voltage mode, when the air pressure value is less than 0.4mmHg, it switches to the blowing mode.

[0074] In the blowing mode, the difference between two adjacent air pressure values ​​is calculated to obtain the first difference, and when five consecutive first differences are greater than 0.02mmHg, the mode is switched to the voltage stabilization mode.

[0075] When the air supply tube 9 is inserted into the human body, the air pressure value will continue to rise, instead of only rising once or twice. For example, the example of inadvertently blowing on the wall in Embodiment 1 will only cause the air pressure value to rise briefly and then drop. Should be wrongly judged to need to switch to regulation mode. In this embodiment, if the air pressure continues to increase by 0.4mmHg within 50ms in the blowing mode, it is determined that there is resistanc...

Abstract

The invention discloses an automatic switching method of a working mode of a pneumoperitoneum machine, an electronic device, a device and a pneumoperitoneum machine, which belong to the field of pneumoperitoneum machines. Air pressure value; in the voltage stabilization mode, switch to the blowing mode when the air pressure value is less than the first preset value; in the air blowing mode, switch to the voltage stabilization mode when the difference between adjacent air pressure values ​​is greater than the second preset value. The automatic switching method of the working mode of the pneumoperitoneum machine sets the timing of switching the working mode of the pneumoperitoneum machine according to the characteristics of the air pressure change of the pneumoperitoneum machine after the trachea is pulled out and inserted into the human body, so that the pneumoperitoneum function can be automatically switched in an appropriate situation intelligently and accurately The working mode, without manual operation, reduces the things that doctors need to take into account during the operation.

Description

technical field [0001] The invention relates to an automatic switching method for a working mode of a pneumoperitoneum machine, an electronic device, a device and a pneumoperitoneum machine, and belongs to the field of pneumoperitoneum machines. Background technique [0002] The pneumoperitoneum machine in the prior art has only one working mode, that is, pulsed air supply. When the gas is filled into the human body, the pneumoperitoneum machine is controlled according to the pressure set by the user to ensure that the gas can support the human tissue without excessive support. At the same time, the maximum air flow does not exceed the flow value set by the user, and the air pressure is periodically controlled during the period. The present application refers to this working mode in the prior art as a "regulated voltage mode". In practical applications, after the pneumoperitoneum machine is pulled out of the human body, in order to avoid the residual gas in the pneumoperito...
