Clinical anesthetic gas purification device for anesthesiology department

Abstract

The invention relates to the technical field of medical instruments, in particular to a clinical anesthetic gas purification device for the anesthesiology department, which comprises a shell, a breather pipe, a top cylinder, a bottom cylinder and a purification pipe, the bottom cylinder is mounted on the bottom surface of the shell, the inner wall surface of the shell is sunken to form an annular groove opposite to the bottom cylinder, and the lower end of the breather pipe is inserted into the annular groove; the upper ends of the purification pipe and the ventilation pipe are sleeved with sleeves, the ventilation pipe and the purification pipe are sleeved with springs, the outer portion of the top barrel protrudes to form a first positioning part of an annular structure, a pressing plate is installed at one end of the first positioning part through a torsional spring hinge, and a purification assembly is installed in the purification barrel. The air purifier is simple in structure, only one purification pipe is arranged after the ventilation pipe is detached, so that whether the air purifier is in a purification state or not can be ensured, opening and closing of a valve are not needed, meanwhile, the purification pipe and the ventilation pipe are detachable, a purification assembly in the purification pipe is also detachable, repeated use can be achieved, and waste is avoided.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to an anesthetic gas purification device for clinical use in the anesthesiology department. Background technique [0002] When the hospital is performing surgical treatment on patients, local anesthesia and general anesthesia can be used for anesthesia during the operation. They can use three anesthesia methods: liquid medicine, gas, and acupuncture. The safest thing at present is to directly inject the anesthesia gas into the patient's respiratory tract through the breathing mask from the gas anesthesia machine, and obtain the anesthesia effect through pharmacological effects. After the operation, the remaining anesthesia gas needs to be disposed of. Currently, anesthesia gas filters are used. Most of them are disposable products. After use, they become waste products, which wastes resources and increases medical costs. Filters are generally filtered through valves. The di...

Problems solved by technology

After the operation, the remaining anesthesia gas needs to be disposed of. Currently, anesthesia gas filters are used. Most of them are disposable products. After use, they become waste products, which wastes resources and increases medical costs. Filters are generally filtered through valves. The diversion of gas, the closing and opening of valves are very inconspicuous. Once one of the valves is not closed or opened, it will affect the flow and filtration of gas, causing danger to patients
