Description
Technical field
The present invention relates to Anesthesia machine technical fields, and in particular to a kind of oxygen humidifying device for Anesthesia machine.
Background technique
Oxygen uptake, to improve the level of human body artery blood oxygen pressure and oxygen saturation, promotes metabolism, is auxiliary for correcting anoxic
Help one of the important method for treating a variety of diseases.But by oxygenerator and the be supplied to patient of hospital be all high-purity oxygen
Gas, therefore it is referred to as the dry oxygen of not moisture, and be containing a small amount of moisture in the air of nature.But if allow disease
People draws dry oxygen for a long time and can stimulate respiratory tract and have the phenomenon that nosebleed out, in order to avoid dry oxygen can stimulate people
Respiratory tract, thus it is certain when using inhalation device it is noted that humidifying to oxygen, therefore the patient of long-term oxygen uptake is answered
Give the oxygen of humidifying.
The general Anesthesia machine in technology only provides auxiliary oxygen uptake at present, that is, has the auxiliary oxygen uptake output end of regulating flow quantity
Mouthful, the gas source of this port output is in medical oxygen cylinder or hospital center's air supply system, and the two is all dry oxygen, and Anesthesia machine sheet
Body does not have humidification device, therefore is supplied to the only dry oxygen of patient respiration.
Summary of the invention
It is an object of the present invention to solve the oxygen of existing the be supplied to patient of Anesthesia machine due to not carrying out at humidifying
The problem of managing, and then the respiratory tract of people is stimulated to lead to bleeding, the present invention provides a kind of oxygen humidifying device for Anesthesia machine, should
