Description

Pneumoperitoneum machine capable of accurately controlling cavity pressure
Technical Field
The utility model belongs to the technical field of medical equipment, and particularly relates to a pneumoperitoneum machine capable of accurately controlling cavity pressure.
Background
The pneumoperitoneum machine is a necessary device for endoscopic abdominal cavity operation, and has the functions of filling carbon dioxide with certain pressure into an operation cavity and maintaining the pressure in the operation cavity so that a doctor can obtain a good operation space by using an operation instrument. Endoscopic surgery is now a widely used minimally invasive surgical procedure, which basically replaces the traditional open surgical procedure, in which a surgical site or the abdominal cavity is inflated with carbon dioxide gas to bulge in order to provide the surgeon with a good operating space and visual field space.
The filling amount of carbon dioxide or the cavity pressure needs to be precisely and finely controlled according to different operation positions, cavity sizes, patient constitutions, adults, children and the like. However, the pneumoperitoneum machine on the market at present cannot accurately monitor the real-time environment in the cavity of the patient and timely regulate and control the filling flow rate and the flow rate of the carbon dioxide; this can easily cause the air pressure in the patient cavity to be out of control, which can cause serious influence to the operation and even endanger the life safety of the patient.
The existing pneumoperitoneum machine is connected with a patient cavity through a single gas pipe, the pneumoperitoneum machine monitors the air pressure in the patient cavity through the single gas pipe, and the simplified working process is as follows: firstly, the air pressure in the air delivery pipe is detected, because the air delivery pipe is communicated with the cavity of the patient, the pressure value in the cavity of the patient is defaulted when the air pressure in the air delivery pipe is detected, if the detected pressure value is lower than the set pressure value, the pneumoperitoneum machine opens the control valve of the carbon dioxide, a certain amount of carbon dioxide is filled into the cavity of the patient through the air delivery pipe, the carbon dioxide is kept filled for a period of time, then the control valve of the carbon dioxide is closed, then the air pressure in the air delivery pipe is detected, and if the detected pressure value is lower than the set pressure value, the control valve of the carbon dioxide is opened again to fill more carbon dioxide until the detected air pressure in the air delivery pipe is equal to the set air pressure value. If the measured air pressure value is higher than the set value, the bypass air control valve is opened again, the excessive air is discharged again until the measured pressure value is equal to the set air pressure value. Therefore, the working state of the pneumoperitoneum machine is the process of intermittent measurement and control through the air conveying pipe, and the air pressure value in the cavity of the patient can fluctuate up and down to change circularly.
Therefore, a pneumoperitoneum machine capable of precisely controlling the pressure of a cavity has been devised to solve the above problems.

The way is the passage of carbon dioxide gas into the patient cavity 44, which is the same as the single gas transmission pipe of the pneumoperitoneum machine in the market, and has the advantages that the valve or the controller used for controlling and measuring in the pneumoperitoneum machine is different, and the operator of the pneumoperitoneum machine sets various parameters of the pneumoperitoneum machine according to the requirements of doctors, such as the gas pressure of the patient cavity 44, the maximum flow of the charged carbon dioxide, the gas flow or the maximum flow during smoke exhaust and air exhaust, the working mode of the exhaust and the like.
After the working parameters of the pneumoperitoneum machine are set by a doctor, the pneumoperitoneum machine firstly detects the working states of various valves and sensors and the current pressure value of gas. Comparing the values of the two gas pressure sensors, calculating the pressure difference to control the opening of the second flow controller 10, so that the gas is filled into the patient cavity 44 at a reasonable flow rate, and as the pressure value of the gas filled into the patient cavity 44 increases, the pneumoperitoneum machine monitors the pressure sensors in real time, and when the value measured by the pressure sensors is equal to the set value, the second flow controller 10 is closed, and the carbon dioxide filling into the patient cavity 44 is stopped. The whole cavity inflation process is continuous, and the inflation pressure does not exceed a set value because the real-time detection of the cavity pressure is carried out through the pressure sensor during inflation. The actions of firstly inflating for a period of time, then measuring the pressure of the cavity and then inflating and deflating can not occur. The inflation control pressure of the pneumoperitoneum machine is a closed loop that can control the pressure level in the patient cavity 44 in a variety of ways.
When a doctor needs to exhaust smoke in the patient cavity 44, the first gas control valve 8 is opened, the first flow controller 6 is opened according to the exhaust flow set by the doctor to remove smoke in the patient cavity 44, the flow rate of exhaust gas is known, then the second flow controller 10 with the same flow is set to supplement the exhausted gas, the first pressure sensor 5 and the second pressure sensor 11 are used for measuring and monitoring the cavity pressure in real time, and the pressure in the patient cavity 44 is always kept at the set pressure value of the doctor.
When a pressure in the patient cavity 44 is above the set point, there are two ways to reduce the cavity pressure: firstly, the second gas control valve 7 is opened to exhaust, the first pressure sensor 5 is monitored in real time, and the second gas control valve 7 is closed until the monitored pressure value is equal to the set value. And secondly, opening the first gas control valve 8 to exhaust, controlling the first flow controller 6 to exhaust at a certain flow rate, and monitoring the value of the second pressure sensor 11 in real time to reduce the pressure of the cavity to a set pressure value.
