Description

Technical Field

[0001] The invention relates to the technical field of medical devices, and more particularly to a quantitative anesthesia gas monitoring and alarm device in an operating room. Background Art

[0002] It is generally believed that anesthesia is a reversible functional inhibition of the central nervous system and (or) peripheral nervous system produced by drugs or other methods. The meaning of anesthesia is to use drugs or other methods to temporarily make the patient lose sensation as a whole or locally in order to achieve painless surgical treatment. In clinical practice, the content of anesthetic gas in the patient's breathing gas is of great significance. Inhaled anesthetic drugs enter the human body through the respiratory tract in the form of volatile liquids or gases to form an anesthetic effect. Common inhaled anesthetics include nitrous oxide, desflurane, sevoflurane, etc. Such anesthetics have an inhibitory effect on the central nervous system. In the process of anesthetizing patients, there is often leakage of anesthetic gas. Since anesthetic gas has an inhibitory effect on breathing, the leakage of anesthetic gas can easily affect the surrounding medical staff. When medical staff anesthetize patients, more or less some anesthetic gas leaks. If there is a leak in the anesthesia system, the concentration of anesthetic gas in the operating room will increase significantly, and these leaked anesthetic gases will cause harm to the operating room staff. At the same time, since anesthetic gas is a strong greenhouse gas, it is easy to aggravate the greenhouse effect if it is directly discharged into the atmosphere. Therefore, gas detection alarms are used in the operating room to monitor harmful gases in real time and give timely alarms.

[0003] In the prior art, a gas call alarm is usually used to monitor and alarm harmful gases, but the anesthetic gas in the air cannot be processed after monitoring. At this time, surgery may be in progress in the operating room, and medical staff cannot be transferred in time. The leaked anesthetic gas will cause certain harm to the medical staff. Therefore, the purpose of the present invention is to provide a device that can quantitatively monitor and alarm the anesthetic gas concentration in the operating room, and can process the anesthetic gas to reduce the anesthetic gas concentration in the room.

The monitored anesthetic gas concentration value is set through the function button of the display control device 9, and the monitoring values ​​of all gas sensors are displayed through the display screen. The gas sensor 27 transmits the monitored anesthetic gas concentration to the integrated circuit board in real time. When the concentration of anesthetic gas monitored by a gas sensor 27 is higher than the set value, under the control of the integrated circuit board, the alarm device 10 issues an alarm reminder and starts the suction pump 3 to work. The suction pump 3 sucks the gas in the operating room and then passes through the air inlet pipe 12 at the outlet end to be diverted into multiple parts in the diversion pipe 14 and sent to the purification box 16 through the connecting pipe 15, and the anesthetic gas is dissolved and eliminated by the organic solvent 168 in the purification box 16.
