Anesthetic gas recovery device for anesthesia machine

Abstract

The invention relates to the technical field of medical auxiliary equipment, in particular to an anesthetic gas recovery device for an anesthesia machine. The anesthetic gas recovery device comprisesthe anesthesia machine, an oxygen tank and a respirator, wherein a bottom plate for supporting is arranged at the bottom ends of the anesthesia machine and the oxygen tank, and double-brake wheels arearranged at four corners of the bottom end surface of the bottom plate; a main guide pipe communicates with the respirator, a waste gas pipe communicates with the end part of the main guide pipe through a first one-way valve, and a recovery frame body placed on the bottom plate communicates with the free end of the waste gas pipe; and an anesthesia pipe communicates with the side wall of the mainguide pipe, a second one-way valve is mounted on the anesthesia pipe, the free end of the anesthesia pipe communicates with the anesthesia machine, and an oxygen pipe communicates with the anesthesiapipe along the position between the second one-way valve and the main guide pipe. The anesthetic gas recovery device for the anesthesia machine designed by the invention is reasonable in structural design, anesthetic waste gas generated in the anesthesia process can be recovered, the anesthetic waste gas is prevented from being guided into air to injure a human body, practicability is high, and the anesthetic gas recovery device has excellent market popularization value.

Description

technical field [0001] The invention relates to the technical field of medical auxiliary equipment, in particular to an anesthetic gas recovery device for an anesthesia machine. Background technique [0002] The anesthesia machine sends the anesthetic into the alveoli of the patient through a mechanical circuit, forming a partial pressure of the anesthetic gas, which diffuses into the blood, and directly inhibits the central nervous system, thereby producing the effect of general anesthesia. The anesthesia machine is a semi-open anesthesia device. It is mainly composed of anesthesia evaporation tank, flow meter, folding bellows ventilator, breathing circuit, corrugated pipeline and other components. Therefore, the demand for anesthesia gas recovery device for anesthesia machine is increasing day by day. [0003] When performing an operation on a patient, the doctor needs to deliver anesthesia gas into the patient's body to achieve anesthesia for the patient. The anesthetic...
