Description
Technical field
The utility model is related to technical field of medical instruments, more specifically, the utility model, which is related to one kind, is used for lung ventilator
Humidifier and lung ventilator with this kind of humidifier.
Background technology
The equipment that lung ventilator refers to treat the apnea and other disordered breathing phenomenons in sleep procedure, it passes through
The patient contacting portions such as mask provide barotropic gas to patient, to aid in patient respiratory, mitigate work of breathing ozone.
Lung ventilator is when carrying out mechanical ventilation, and gas must first pass through temperature, humidifying processing, could be entered by lung ventilator air flue
Enter patients with respiratory tract, if the gas without temperature, humidifying is directly entered respiratory tract, ventilation for a long time necessarily causes respiratory tract to lose
Water, mucous membrane are dry, secretion is dry and hard, ciliary movement decrease, expectoration be not smooth, easily occur airway obstruction, atelectasis and secondary sense
The complication such as dye.
Therefore, the lung ventilator of current Clinical practice is equipped with humidifier substantially, to carry out temperature, humidifying processing to gas, makes
Gas in suction patient's body is warm and moistens, and reduces stimulation of the cold gas dried to respiratory mucosa, is that patient brings
More comfortable usage experience.Specifically, lung ventilator mainly includes main frame, humidifier, breathing pipeline and mask, and humidifier enters
One step includes humidifier body, the humidifying room coupled with humidifier body and the heating plate being arranged in humidifier body.Breathing
The operation principle of machine is：After energization, the water in humidifying room produces vapor because of the heat effect of heating plate, now, and main frame is supplied
Gas is answered into humidifying room, with by the vapor in humidifying room to gas carry out temperature, humidifying, through excess temperature, humidifying gas from
Humidifying room, which is flowed out and passes through breathing pipeline, is carried to patient.
It can be seen from the operation principle of lung ventilator, patient or medical personnel need to inject into humidifying room before the use
The water of certain volume, then couples humidifying room and humidifier body, and then access the gas passage of lung ventilator.In practical operation
In, the water injected in humidifying room is probably unable to reach optimum state, and then is unable to reach expected application target.This embodies
：When patient uses lung ventilator, the water that the excessive water of injection may result in humidifying room is sprayed and passed through and breathe by gas
Pipeline enters patient oral cavity, causes patient to choke water；And very few water is injected, water can be depleted after being run by the short time,
Now humidifier can not recur to expected temperature, humidifying effect, more seriously, can also be because humidifier is still in heating shape
State and cause output gas overtemperature, in turn result in patients with respiratory tract scald.
In view of the above-mentioned problems, the first existing solution is：In humidifying chamber surface silk-screen or it is molded some water levels
Minimum value, maximum or mid-scale, so that patient recognizes height of water level in current humidifying room when in use, voluntarily determine whether
It is adapted to humidifying demand.Although this kind of solution cost is low and easily fabricated, due to dependent on eye recognition, therefore can not
Carry out automatic warning.
Existing second of solution is the temperature-detecting device that increase is used to detect temperature of heating plate, to pass through measurement
The rate temperature change of heating plate determines the water level in humidifying room, is specially：When lung ventilator is run, detecting signal unit detection
The initial temperature T0 of heating plate, then power control unit control conveying power is to heating plate, after heating certain time Δ t, then
Secondary detection temperature of heating plate Tm, calculates rate temperature change R=(Tm-T0)/Δ t, by result of calculation and the demarcation prestored
Data are compared, and determine water level in humidifying room；Or, detecting signal unit detects the initial temperature T0, Ran Hou electricity of heating plate
Source control unit control conveying power persistently detects temperature of heating plate, when temperature reaches Tm, calculates the heat time to heating plate
After Δ t, rate temperature change R=(Tm-T0)/Δ t is then calculated, result of calculation and the nominal data that prestores are compared
It is right, determine water level in humidifying room.
Although second of solution is independent of eye recognition, automatic warning can be carried out, add due to being transported to
The power of hot plate is by adversely effecting temp rate of change, and larger heating power can be such that the water of same volume heats faster, and
It is slower that less heating power heats the water of same volume, and because the precision of heating plate is subject to processing the limitation of precision, very
It is very accurate that difficulty is done, and is also difficult to accomplish that heating power is precisely controlled, therefore, and water temperature change speed can not be ensured by eventually resulting in
The computational accuracy of rate.Further, since the water in injection humidifying room is generally the mineral water or running water being commonly used in family,
Rather than special pure distilled water, even if therefore identical heating power, same volume water, the temperature within the heating identical time
Degree, which rises, to be also not quite similar, and this can also influence the accuracy that water level judges.Furthermore, the heating power of heating plate generally will not be too
Greatly, generally 30W or so, and the volume for allowing the water of storage in humidifying room wants to heat the water to one about within 300ml
The individual temperature range that can be recognized, generally requires heating longer time and just can determine that height of water level, can so cause patient to make
With just can know that in humidifying room that water level is not suitable for after a period of time, Consumer's Experience is greatly reduced.
Therefore, it is necessary to the structure of humidifier be improved, to improve the accuracy of detection and detection real-time of automatic water level detection.
