Affiliated technical field

A kind of novel oxygen humidifying device that uses when the present invention relates to clinical oxygen therapy belongs to the medical apparatus and instruments category that hospital clinical uses.

Background technology

Oxygen therapy is one of the most frequently used rescue of hospital or treatment means, because the humidity of oxygen itself is very low, long-time oxygen uptake meeting causes dry and cracked hemorrhage, the sputum of patient respiratory road drying, nasal mucosa to be difficult for adverse consequencess such as expectoration, generally wants to carry out humidifying to oxygen earlier when therefore carrying out oxygen inhalation therapy clinically and handles.The widely used oxygen humidification method of hospital is that humidification fluid (being generally aquesterilisa or distilled water) is filled in the humidifying cup (bottle) of oxygen inhalation apparatus at present, by the inner core of humidifying cup (bottle) oxygen is overflowed by back below the humidification fluid liquid level then and make it to be able to humidifying, enter at last in the patient respiratory road.Find that by a large amount of clinical observations mainly there is following defective in existing humidifying method:

1, oxygen enters the following back of humidification fluid liquid level effusion liquid level fast, and the holdup time of oxygen in the humidifying thing is extremely short, and oxygen bubble is big and can't disperse, the unit contact area of oxygen and humidification fluid seldom, so the humidifying effect is unsatisfactory.

The water vapor bubbles noise that produces when 2, oxygen enters humidification fluid brings discomfort for a lot of patients, and critical patient, patients with heart failure and the neurastheniac of the rest that particularly needs peace and quiet is particularly responsive.

The inventor once proposed " a kind of noiseless oxygen humidifying device (ZL200820177959.2) " technical scheme, produced the problem of water vapor bubbles noise when efficiently solving oxygen inhalation wet.But find in practice simultaneously, because each different oxygen uptake patient has lack of uniformity (usually between 1～8L/min) to oxygen flow, this technical scheme when the low discharge oxygen supply that is lower than 3L/min during with the high flow capacity oxygen supply that is higher than 5L/min since the different humidity that cause of current rate of input oxygen generation differ greatly; And when the humidification fluid liquid level continued to descend, the oxygen humidification effect weakened, and the oxygen humidity of humidification device output also decreases.

For this reason, the inventor proposes a kind of novel oxygen humidifying device, belongs to a kind of technical spirit improvement project of novel noiseless oxygen humidifying device, effectively solves the oxygen humidification effect attenuation problem of generation when the low discharge oxygen uptake reduces with the humidifying thing.
