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 a pneumoperitoneum machine working mode automatic switching method, electronic equipment, a device and a pneumoperitoneum machine, and belongs to the field of pneumoperitoneum machines.The method comprises the steps that in a blowing mode and a pressure stabilizing mode, air pressure values are continuously obtained according to a first time interval; in the pressure stabilizing mode, when the air pressure value is smaller than a first preset value, the air blowing mode is switched; in the blowing mode, when the difference between the adjacent air pressure values is larger than a second preset value, the mode is switched to the pressure stabilizing mode. According to the method for automatically switching the working modes of the pneumoperitoneum machine, the opportunity for switching the working modes of the pneumoperitoneum machine is set according to the characteristic that the air pressure of the pneumoperitoneum machine changes after the air supply pipe is pulled out of and inserted into the human body, so that the pneumoperitoneum machine can intelligently, accurately and automatically switch the working modes in a proper scene, manual operation is not needed, and things needing to be considered by a doctor in an operation are reduced.

Description

technical field [0001] The invention relates to a method for automatically switching the working mode of an insufflation machine, electronic equipment, a device and the insufflation machine, belonging to the field of insufflation machines. Background technique [0002] The insufflation machine in the prior art has only one working mode, that is, pulsed air supply. When the gas is inflated into the human body, the insufflation machine is controlled according to the pressure set by the user to ensure that the gas can support the human tissue without excessively supporting it. Injury to human tissue, while the maximum airflow does not exceed the flow value set by the user, during which the air pressure is periodically controlled. The present application refers to this working mode in the prior art as "voltage stabilization mode". In practical application, after the insufflation machine is pulled out of the human body, in order to prevent the gas remaining in the insufflation m...
