Clinical anesthetic gas purification device for anesthesiology department

Abstract

The invention belongs to the technical field of medical instruments, and particularly relates to a clinical anesthetic gas purification device for the anesthesiology department, the clinical anesthetic gas purification device comprises a base, a purification box is fixedly connected to the base, a filter screen and a fixing seat are fixedly arranged in the purification box, an opening groove is formed in the fixing seat, and a wetting cotton layer is fixedly arranged in the opening groove; an opening groove is formed in the purification box, an annular water guide cavity is formed in the opening groove and communicates with the opening groove through a plurality of spray pipes, pressure valves are arranged on the spray pipes, a water guide mechanism matched with the annular water guide cavity is arranged on one side of the purification box, and a humidity detection mechanism matched with the water guide mechanism is arranged on the purification box. According to the device, sufficient mixing of oxygen and anesthetic gas can be guaranteed, filtered mixed gas can be wetted, the humidity of the mixed gas is guaranteed, meanwhile, water can be automatically supplemented to a wetting cotton layer, and the usability of the device is greatly facilitated.

Description

technical field [0001] The invention belongs to the technical field of medical devices, in particular to an anesthesia gas purification device for clinical use in anesthesiology. Background technique [0002] Anesthesiology is a comprehensive discipline, which contains multidisciplinary knowledge and has a wide range. It not only meets the requirements of surgery, but also participates in the rescue work of various departments, painless childbirth in gynecology, painless abortion, etc., to ensure that patients It is the basic task of anesthesia clinic to successfully accept surgical treatment under painless and safe conditions. [0003] At present, in the process of anesthesia, it is often necessary to mix oxygen into the anesthesia gas to avoid hypoxia in the patient during the anesthesia process. In order to ensure the cleanliness of the gas, the gas is often filtered through a purification device. However, the traditional purification device Generally, it can only play a...

Problems solved by technology

[0003] At present, during anesthesia operations, it is often necessary to mix oxygen into the anesthesia gas to avoid hypoxia in the patient during anesthesia. In order to ensure the cleanliness of the gas, the gas is often filtered through a purification device. However, the traditional purification device Generally, it can only play a simple filtering role, and cannot keep the filtered gas at a certain humidity. Because the anesthetic gas is easy to dry, it will affect the comfort of the patient's inhalation. At the same time, the traditional purification device cannot effectively improve the mixing of anesthetic gas and oxygen. The adequacy of the gas affects the effect of the gas
