Anesthetizing device capable of performing anaesthetic concentration adjusting

Abstract

The invention discloses an anesthetizing device capable of performing anaesthetic concentration adjusting. The anesthetizing device capable of performing anaesthetic concentration adjusting comprisesa gas tank, a pair of sucking chambers, a piston chamber, a housing and an anesthetizing gas tank, wherein the piston chamber is arranged at the middle position of the inner part of the housing; the sucking chambers are symmetrically arranged on two sides of the piston chamber, in the housing; and first pistons each of which cooperates with the corresponding sucking chamber are arranged in the corresponding sucking chamber. According to the anesthetizing device capable of performing anesthesia concentration adjusting disclosed by the invention, communicating pipes are connected between the sucking chambers on two sides and a piston groove, and the volume of the piston groove is smaller than the sum of the volumes of the sucking chambers on two sides and is greater than the volume of a single sucking chamber, so that in the using process, the anesthetizing device disclosed by the invention can conveniently mix enough anaesthetics in one time to allow a patient to use; the moving of thefirst pistons is driven by the moving of a second piston, so that the sucking, the mixing and the extruding of inhalation anaesthetics and diluent air are realized simultaneously by motor driving, andthe situation that the anaesthetic concentration of the next time is influenced by air remained in the piston groove or the anaesthetics of different concentrations adjusted in the last time is avoided, the accuracy of anaesthetic concentration adjusting is promoted, the using is convenient, and the practical using effect is better.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to an anesthesia device for adjusting anesthesia concentration. Background technique [0002] Anesthesiology is a comprehensive discipline, which contains multidisciplinary knowledge. Now the scope is wider, not only to meet the requirements of surgery, but also to participate in the rescue work of various departments, gynecological painless childbirth, painless abortion, etc., to ensure that patients undergo surgery smoothly under painless and safe conditions, It is the basic task of clinical anesthesia. Anesthesia work also includes preparation and treatment before and after anesthesia, monitoring and treatment of critically ill patients, emergency resuscitation, pain treatment, etc. Anesthetics need to be prepared during the use of anesthesia, so anesthetics are needed Concentration adjustment device. [0003] At present, the existing anesthesia concentration adjustment...

Problems solved by technology

[0004] The object of the present invention is to provide a kind of anesthesia concentration adjustment anesthesia device, to solve the problem that the existing anesthesia concentration adjustment anesthesia device proposed in the above background technology is inconvenient to adjust the concentration of anesthesia arbitrarily in the process of adjusting the anesthesia concentration. The accuracy is poor, the operation is complicated, the mixing of anesthesia and dilution gas is complicated, and the uneven mi
