Respiration assisting device for critically-ill patient

Abstract

The invention discloses a respiration assisting device for a critically-ill patient. According to the respiration assisting device, a gas supply switching component can be automatically switched between main oxygen cylinder gas supplying and auxiliary oxygen cylinder gas supplying according to a size of pressure in a main oxygen cylinder; when a pressure value in the main oxygen cylinder is greater than a set value, a respiration outgoing gas control valve seat is subjected to gas supplying by the main oxygen cylinder; when the pressure value in the main oxygen cylinder is smaller than the setvalue, the respiration outgoing gas control valve seat is subjected to gas supplying by an auxiliary oxygen cylinder; automatic switchover of gas supply between the main oxygen cylinder and the auxiliary oxygen cylinder can be effectively achieved; and after a new main oxygen cylinder is replaced when the pressure value of the main oxygen cylinder is smaller than the set value, the gas supply switching component can enable the main oxygen cylinder to supply gas to the respiration outgoing gas control valve seat again and meanwhile the auxiliary oxygen cylinder is subjected to inflated treatment, the reliability and persistency of oxygen supplying can be effectively guaranteed, the problems of instant interruption and the like are prevented, and the stability of heart and lungs of a patient is improved.

Description

technical field [0001] The invention relates to the technical field of medical equipment, in particular to a breathing assistance device for critically ill patients. Background technique [0002] For critically ill patients, oxygen infusion machines are generally required for assisted breathing. Since critically ill patients generally need to perform assisted breathing for a long time, this will lead to adverse effects on the patient if the oxygen in the oxygen cylinder becomes less or exhausted, and if it cannot be replaced in time, and even if it is replaced, during the replacement period, It will also easily affect the breathing condition of the patient, causing adverse fluctuations in the heart and lungs. At the same time, because the temperature and humidity of the oxygen cylinder will also be slightly different, this will easily cause discomfort to the critically ill patient after replacement, resulting in a relatively weak heart and lung of the patient. Large fluctua...

Problems solved by technology

Since critically ill patients generally need to perform assisted breathing for a long time, this will lead to adverse effects on the patient if the oxygen in the oxygen cylinder becomes less or exhausted, and if it cannot be replaced in time, and even if it is replaced, during the replacement period, It will also easily affect the breathing condition of the patient, causing adverse fluctuations in the heart and lungs. At the same time, because the temperature and humidity of the oxygen cylinder will also be slightly different, this will easily cause discomfort to the critically ill patient after replacement, resulting in a relatively weak heart and lung of the patient. Large fluctuations, this kind of fluctuation generally does not have a great impact on ordinary patients, but for severe patients, this fluctuation may have a greater adverse effect on the rehabilitation of severe patients. Therefore, how to improve the The patient's breathing assistance ability, and maintaining this state at all times, plays an extremely important role in the first aid of critically ill patients
