Pneumoperitoneum machine calibration device and method with constant pressure stabilizing mechanism

Abstract

The invention provides a pneumoperitoneum machine calibration device and method with a constant pressure stabilizing mechanism. The pneumoperitoneum machine calibration device comprises an abdominal cavity simulation box, a barometer is fixedly connected to one side of the top end of the abdominal cavity simulation box, two fixed columns are fixedly connected to the top end of the abdominal cavity simulation box, and a control panel is jointly and fixedly connected to the top ends of the two fixed columns. A power line is fixedly connected to one side of the control panel, a plug is fixedly connected to one end of the power line, an air inlet mechanism is arranged on one side of the abdominal cavity simulation box, an air outlet mechanism is arranged on the other side of the abdominal cavity simulation box, an adjusting mechanism is arranged at the inner bottom of the abdominal cavity simulation box, and a temperature sensor is fixedly connected to the inner top of the abdominal cavity simulation box. The pneumoperitoneum machine calibration device has the beneficial effects that various real-time detections can be carried out during gas input and output, relevant data during simulation can be found in time, the loading capacity of the simulated abdominal cavity can be conveniently adjusted, calibration simulation can be carried out on patients with different loading capacities of the abdominal cavity, and centralized control and observation can be carried out on the device.

Description

technical field [0001] The invention relates to the technical field of medical device calibration, in particular to a calibration device and method for an insufflation machine with a constant pressure stabilizing mechanism. Background technique [0002] The insufflation machine is a special equipment for establishing and maintaining the pneumoperitoneum in laparoscopic surgery. The function of the insufflation machine is to establish an artificial pneumoperitoneum, which is to separate the abdominal wall from the viscera through the mechanical pressurization and inflation of the insufflation machine, so as to provide enough space for the operation. operating space, and can avoid damage to the viscera when the puncture sleeve pierces the abdominal cavity, the existing insufflation machine calibration device also has the following defects: [0003] The existing insufflation machine calibration device only inputs the gas when the gas is input for calibration, and there is no co...
