The disclosure provides a ventilation apparatus. The ventilation apparatus includes a housing, an inhalation branch, a control unit, a gas source port, an exhalation branch, and a paramagnetic oxygen sensor. The paramagnetic oxygen sensor is used for detecting the oxygen content in the inhalation branch. The gas source port is disposed on the housing. The inhalation branch, the control unit, and the exhalation branch are enclosed within the housing. The paramagnetic oxygen sensor is disposed outside the housing.

Ventilation apparatus

An anesthetic evaporator is provided. The anesthetic evaporator includes a housing, an anesthetic agent storage tank, a cover, a mechanical pressure relief assembly connected with the anesthetic agent storage tank, and a linkage mechanism. The mechanical pressure relief assembly is provided with a first state in which a pressure within the anesthetic agent storage tank is maintained and a second state in which a pressure within the anesthetic agent storage tank is released. When adding an anesthetic agent, an operation action on the anesthetic evaporator drives the linkage mechanism, and the linkage mechanism drives the mechanical pressure relief assembly to be switched from the first state to the second state.

Anesthetic evaporator and anesthesia machine

An anesthesia machine, an anesthetic output concentration monitoring method, system, a device, and a storage medium are disclosed. The method includes respectively monitoring a flow of a fresh gas flowing into a breathing circuit and a flow of an inhaled gas of an anesthetized object. The method further includes when the inhaled gas flow is greater than a fresh gas flow, respectively monitoring a concentration of anesthetic in the inhaled gas and an exhaled gas of the anesthetized object. The method also includes using the exhaled gas anesthetic concentration and a concentration of carbon dioxide in the exhaled gas to calculate a concentration of anesthetic in a gas, reflowing into an inspiratory branch, in the exhaled gas, thereby obtaining a re-inhaled gas anesthetic concentration. The method additionally includes using the fresh gas flow, the inhaled gas flow, the inhaled gas anesthetic concentration, and the re-inhaled gas anesthetic concentration to calculate a concentration of output anesthetic of an anesthetic output device, thereby obtaining an anesthetic output concentration.

Anesthesia machine, anesthetic output concentration monitoring method, system, and device, and storage medium

An anesthetic evaporator locking structure for detachably connecting an anesthetic evaporator to an anesthesia main machine is disclosed. The anesthetic evaporator includes a main body and a securing member provided on the main body. The anesthesia main machine includes a driving element and a mating member provided on the anesthesia main machine. The securing member and the mating member mate with each other to form a primary locking mechanism, and when the anesthetic evaporator is in an activated state, the driving element limits the primary locking mechanism to realize secondary locking. The anesthetic evaporator further includes a handle provided on the main body and an unlocking device provided on the handle, and the unlocking device is used for unlocking the primary locking mechanism. The anesthetic evaporator locking structure can realize the double locking and has relatively high safety, and both the locking and unlocking processes can be operated by one hand, which is convenient and quick.

Anesthetic evaporator locking structure and anesthesia machine

The present disclosure provides a ventilator that includes a first gas path, comprising a first pressurized gas source adaptor and a first flow adjustment device connected in sequence; a second gas path, comprising a second pressurized gas source adaptor and a second flow adjustment device connected in sequence; a third gas path, comprising a third pressurized gas source adaptor; a first inhalation branch for delivering inhalation gas to a patient; a second inhalation branch for delivering inhalation gas to the patient, including a gas compression device; a switching device, including a first mixing mode connecting the first gas path and the second gas path to the first inhalation branch, and a second mixing mode connecting the first gas path and the third gas path to the second inhalation branch; and an exhalation branch for managing exhaled air of the patient.

Ventilator and gas supply control method thereof

An oxygen sensor seat assembly, an oxygen sensor assembly, and an anesthesia machine are disclosed.

Oxygen sensor seat assembly, oxygen sensor assembly, and anesthesia machine

A thermometer quick linkage apparatus comprises an elastic member, a button, a probe, and a chamber having one end provided with an opening for receiving the end portion of the probe, and the other end also provided with an opening for receiving the button. Within the chamber, one end of the elastic member connects with the button, and the other end thereof connects with the probe. The elastic member is configured such that, when the button is pressed to compress the elastic member to a certain degree, the end portion of the button comes into contact with the end portion of the probe, and when the button is pressed further down, the probe is pushed away from the chamber. The apparatus is simplified in structure, and allows quick replacement of the probe jacket, and therefore is cost-efficient.

Thermometer quick linkage apparatus and method

Disclosed is an apparatus for installing a carbon dioxide absorbent canister which comprises a body, a lifting member, and a lifting mechanism. The body comprises a breathing circuit and an adapter for connecting the carbon dioxide absorbent canister with the breathing circuit. The adapter is located at or near the bottom of the body. The lifting member comprises a base portion, a positioning portion beneath the adapter, and a connecting portion. The lifting mechanism has a force receiving portion and a force applying portion and which actuates the lifting member. Actuating the handle in the first direction causes the canister to be connected to the breathing circuit and to close the breathing circuit bypass. Turning the handle in a second direction actuates the canister to enable replacement of the canister and to cause the breathing bypass to open. The process can be achieved simply with one hand.
