Description
Technical field
The present invention relates to medical breathing apparatus technical fields, more particularly to a kind of humidification machine for invasive ventilation.
Background technique
Ventilator has been commonly used to breathing caused by a variety of causes and has declined as a device with artificial ventilation's function
It exhausts, in the treatment of diseases such as sleep apnea low-ventilatory syndrome, highly important position is occupied in Modern Medical Field
It sets.Usual ventilator needs that humidification machine is cooperated to be used together.Humidification machine be it is a kind of have can change breathing gas temperature and wet
The respiratory tract of the device of degree, normal human has humidifying and temperatureization to act on the gas of sucking, this is that respiratory system non-specificity is anti-
The pith of imperial function.The heating and moistening of physiological is mainly completed in nasopharyngeal cavity, gas reach retropharynx when temperature about
It is 30 DEG C, relative humidity about 95%, absolute humidity about 30mg/L, remaining is accomplished below in glottis, and the gas for eventually entering into alveolar is
Saturated humidity under body temperature, i.e., 37 DEG C, relative humidity 100%, absolute humidity 43.9mg/L.Gas is usually reached into body temperature
Under the conditions of saturated humidity position be isothermal saturation region (Isothermic saturation boundary, ISB), when normal
ISB is located at the grand ridge of bronchus to oxygen therapy is received between the 4th~5 grade of bronchus Asia section or establishes the patient of artificial airway, upper breathing
This heating and moistening function in road can completely or partially be lost, and the heating for sucking gas and humidification function are mainly by tracheae --- branch gas
Pipe tree mucous membrane is completed namely ISB is moved down, and Yi Yinqi tracheal mucosa is dry, and secretion is sticky, cilia activity weakens or disappears,
Expectoration is unsmooth, or even airway obstruction, the serious complication such as atelectasis and lower respiratory tract infection occurs.Studies have shown that is when sucking
When the humidity of gas drops to 70% or less, lower respiratory tract cilium will stop swinging.Human body expiratory air is also body temperature under physiological conditions
Under the conditions of saturated humidity, with naturally suck air be 22 DEG C (relative humidity 50%, absolute humidity 10mg/L) for, expiratory air 37
DEG C (relative humidity 100%, absolute humidity 43.9mg/L) is that 6~8L is calculated with minute ventilation volume under tranquillization, can calculate body
Daily air flue fluid loss (43.9-10) × 6 × 60 × 24mg of patient of weight 60kg is 300~400ml.It can be seen that sucking gas is more dry
Dry, air flue dehydration is more, and minute ventilation is bigger, and air flue dehydration is more, and body temperature is higher, and air flue dehydration is more.Therefore, gas
Heating and humidifying are keeping airway mucus --- and the normal physiological function and defense function of cilium system reduce air flue dehydration, are anti-
It controls and plays very important effect in the generation of various complication.
The air-flow of existing humidification machine is directly entered from air inlet, and air-flow may not come into full contact with the water surface with regard to direct
It is come out from gas outlet, humidifying effect is poor, and the comfort level that user experiences is inadequate.In addition, water tank and the heating of existing humidification machine
Component is separation, and heating effect is poor, and humidification machine structure is more complicated, and cost of manufacture is higher.
Therefore, in the prior art there are problem, that it is urgent to provide a kind of structures is simple, cost is relatively low, heating and wet
Changing effect, good humidification machine technology is particularly important.
