Description
Technical field
The present invention relates to a kind of breather valve for improving double air pressure ventilator performances, the invention further relates to a kind of breathing equipment,
Belong to medical instruments field.
Background technique
Ventilator clinically mainly solves the problems, such as ventilation and oxygen uptake.In recent years, double air pressure ventilators are due to structure letter
It is single, it is easy to use, it is cheap, it is used extensively by clinical even family.Double air pressure Use of respirator single tubes connection ventilators and
Nose cup or mask, it is easy to connect, but there is also some problems:
One, exhalation passages are indefinite, the edge of the leakage hole of mask, the connector with leakage hole, even nose cup and mask
Leakage part be expiration carbon dioxide discharge-channel.
Two, leakage rate is uncertain.Pressure of inspiration(Pi) is set according to the patient's condition, in addition to considering complying with for patient's lung
Property, patient's tidal volume demand, it is also contemplated that it is that may be present repeat suck.Leakage rate depends on airway pressure and leakage again
Equivalent bore.
Three, due to above-mentioned 2, clinically carbon dioxide retention risk is bigger when double air pressure breathing machine ventilations,
Big leakage rate cannot even establish pressure in air flue, and small leakage rate CO2 emission is unsmooth；Need clinical experience
Repeatedly adjusting with double air pressure Use of respirator experiences than more rich doctor can be only achieved satisfied effect.
Four, it is uncertain to be also due to leakage rate, oxygenation becomes difficult point in pipeline.Improving fraction of inspired oxygen is that clinical treatment lacks
The main means of oxygen are applied directly to connecting pipe, and most of oxygen is discharged to atmosphere with leakage, it is necessary to waste a large amount of oxygen
Fraction of inspired oxygen can be improved.The minute ventilation of actual fraction of inspired oxygen and leakage rate, patient is related, uncertain leakage rate
Also imply that uncertain fraction of inspired oxygen
Five, it is leaked due to existing, the gas supply flow of double air pressure ventilators is much larger than the inspiratory flow of patient.In such case
Under, one of the problem of warming humidification of gas also becomes double air pressure ventilators.
Under conditions of not leaking either leakage very little, expiratory air has specially for the ventilator work of clinical non-double air pressure classes
The exhalation channel of door there's almost no repetition sucking, and the gas supply flow of ventilator and the inhalation flow of patient are very close, heating
Humidifying is easier.But it is expensive that there are ventilators, problem complicated for operation.
Summary of the invention
The purpose of the present invention is to provide a kind of breather valves and its breathing equipment for improving double air pressure ventilator performances, with solution
The certainly above problem.
Present invention employs following technical solutions:
The present invention provides a kind of breather valve for improving double air pressure ventilator performances characterized by comprising mutually fastens

Advantageous effect of the invention
The breather valve and its breathing equipment of the double air pressure ventilator performances of raising of the invention, double air pressure ventilators once connect
Breather valve and pipeline of the invention can achieve the effect of large-scale or professional ventilator invasive ventilation.
1. expiration gas has special discharge-channel, carbon dioxide is not susceptible to retention phenomenon.
2. the special discharge-channel of expiration gas can collect patient's exhaled gas, especially there is the disease by breath transmission
People uses ventilator.
3. there is breather cheek valve in air intake passage, patient's expiratory air cannot be flowed through to suction pipe, and there is no repeat to suck
Problem.
4. there is expiratory one-way valve in exhalation passages, patient can not repeat sucking expiratory air, while also improve synchronous triggering
Sensitivity.Because the inspiratory effort of patient all passes through suction pipe and passes to ventilator, rather than part.
5. oxygen can be inputted at breather valve position, because seldom or there is no leakage, the consumption and waste of oxygen are few.
Oxygen concentration is also easy to calculate and control.
6. oxygen flow has minimum flow function concurrently, ventilation efficiency can be improved.
7. the flow due to flowing through pipeline adds sucking gas after accessing humidification machine close to the minute ventilation of patient
Temperature humidification is significantly improved than double air pressure ventilator effects.
