Laparoscopic surgery has the advantages of small trauma, light pain, fast recovery, reliable efficacy, etc., and is currently more and more used in clinical surgery, but in the process of laparoscopic surgery, carbon dioxide (CO2) needs to be filled with carbon dioxide (CO2) to establish pneumoperitoneum, in recent years, the impact of CO2 pneumoperitoneum on the body has attracted the attention of many scholars, but often only pay attention to the impact on the patient's body, and ignore the impact on the medical worker's own body.
Clinical data: CO2 gas is a colorless and odorless gas at room temperature, with a slightly larger density than air and a content of about 0 03 in fresh air. There are no uniform regulations on the maximum allowable levels of carbon dioxide in indoor air. If the ideal range is 900 1800 mg m3 (0 046 0 09) for the general healthy population, the World Health Organization recommends a CO2 concentration of 1800 mg m3 as the ideal concentration or accessible concentration for long-term indoor human exposure, and is adopted by most countries in the world as the indoor air quality concentration limit. CO2 itself is not toxic, but when the amount of CO2 in the air exceeds the normal level, it will have harmful effects on the human body, the most important thing is to stimulate the human respiratory center, resulting in shortness of breath, increased inhalation, and can cause headaches, confusion and other symptoms. According to the results of toxicological and epidemiological studies, the results show that when the indoor air CO2 concentration is 0 07, the human body feels good when the CO2 concentration reaches 0 01, and individual sensitive people have an uncomfortable feeling when they are in such a room for a long time, they will feel uncomfortable, lack of energy, and even affect their health, when the CO2 concentration reaches 0 15, the discomfort is obvious, and the indoor hygiene condition deteriorates significantly when the CO2 concentration reaches 0 15.
Cause of leakage: CO2 concentration used in laparoscopic surgery 99 5 If the leak is leaked, it is easy to increase the CO2 concentration in the operating room, causing potential harm to the personnel in the operating room. The causes of the leakage are analyzed as follows: The gas leakage is not tightly connected at the interface between the pneumoperitoneum pipeline and the gas cylinder, resulting in chronic gas leakage; The pneumoperitoneum tube is not tightly connected to the outlet of the pneumoperitoneum machine, resulting in gas leakage; The operator and the assistant are negligent in their consciousness, and the TROCAR switch is not closed or the connection hole of the laparoscopic instrument is not closed, resulting in the release of CO2 from the opening; The aging and damage of the rubber cap on the TROCAR lead to the chronic leakage of CO2 gas when the laparoscopic instrument enters the TROCAR operation; During the operation, the intra-abdominal CO2 was not sucked up in time during the expansion of the trocar incision to take the specimen or the intraoperative laparotomy and allowed it to escape from the incision into the room; After the operation, the surgeon did not suck out the residual air in the abdominal cavity in time when removing the trocar, resulting in the residual CO2 escaping from the incision to the operating room. After the operation, the main switch of the gas peritoneum and the gas cylinder was turned off without absorbing the residual CO2 in the pipeline, resulting in instantaneous residual CO2 leakage when the gas cylinder was disassembled. All of the above causes can lead to CO2 leakage for a long time, and the medical staff involved in the operation will obviously feel dizzy, swollen, and obviously uncomfortable. Only through the operation and cooperation of medical staff and the constant care to avoid CO2 gas leakage in the process of establishing pneumoperitoneum can we create a healthy operating room environment for participants.
Equipment model: STORZ pneumoperitoneum machine 26432020
1.Visual inspection: check that the appearance of the host is complete and there is no obvious sign of external damage. (No Border).
2.Boot detection: the host is connected to the power supply, abnormal noise during use, the pressure value is large, and the code is occasionally garbled.
3.Detection and diagnosis: Occasional garbled code detection is a problem with the motherboard, the program chip on the motherboard is damaged, several chip signal deviations, several signal points are too large numerical deviations, multiple chips are damaged, the pressure value is too large, it needs to be calibrated, the motherboard needs to be eliminated, and the abnormal noise is the fault of the secondary regulator valve, and the gasket is aging. Equipped with a machine frame.
4.Maintenance plan 1: Repair the main board Repair the secondary pressure regulator valve Equipped with the machine frame Repair and clean the gas circuit and calibrate the parameters.
Repair cycle: 4 working days.
Warranty duration: 6 months.
