Description
Technical field
This utility model belongs to technical field of medical instruments, particularly relates to a kind of noninvasive ventilator device.
Background technology
Sleep-apnea (Sleep Apnea Syndrome.SAS) is a kind of common and sleep disordered breathing disease of coming into one's own day by day.China SAS patient is more than 2,000 ten thousand. and its sickness rate in the adult is very high, and the male is about 4%, and the women is about 2%.Old people's sickness rate is about 50%.Snoring, Fa Zuo hypopnea or asphyxia repeatedly when the SAS1 clinical manifestation is sleep.SAS has a strong impact on patient and other people sleep quality. and severe patient can cause the complication of important vital organs such as cardio-cerebral-pulmo and kidney.Treatment to SAS can be adopted methods such as behavior therapy, continuous positive airway pressure, operative treatment and Drug therapy, and wherein the continuous positive airway pressure treatment has become the generally acknowledged the most effective and safe method of SAS treatment, and commonly used is the noinvasive ventilator.
The key that sleep apnea takes place is the stenosis or occlusion of air flue, the various noinvasive ventilators of therefore treating SAS are all based on so a kind of ultimate principle: suitable Positive Airway Pressure is provided when the patient sleeps, it is unimpeded with the air-flow that ensures respiration to strut air flue, reaches the purpose of eliminating apnea.The characteristics of this kind machine are that the pressure of inspiratory phase and expiratory phase is regulated respectively, and the sleep machine is sent higher default pressure of inspiration(Pi) when promptly air-breathing, help the patient with in the more gas suction body; During expiration, the sleep machine is converted to default lower expiratory pressure automatically, and the patient is easy to the gas in the lung is breathed out.Pressure demand according to reality, the method of main at present employing Fig. 1 is carried out supercharging, by blower fan airborne gas is pressed into the machine intimate cavity, by breather valve air-flow is transported to the connection tube place again, be transported to patient's face shield part again by connection tube, to reach the effect that patient is applied gas pressure.Device is installed flow transducer simultaneously on gas circuit, and at face shield part setting pressure pick off.When patient is in the expiration state, gas direction to breather valve from face shield flows, and need switch this time to valve, and the cavity of patient end is communicated with air vent, the gas of breathing out is arranged to atmosphere, and the method can tentatively realize alternately supercharging and deflated respiratory function.But the method is to adopt the several cavitys of breather valve in valve directly to switch, and does not have transient process in the middle of the air channel, causes air pressure directly to communicate with low from height, produces very big noise, therefore need install silencing means additional, has increased cost.Also have panel to be installed in machine intimate, because the drive current of blower fan is very big, cause temperature rise very high, heating is serious.
Summary of the invention
That the purpose of this utility model is to provide is simple in structure, noiselessness, noninvasive ventilator device with low cost.
The purpose of this utility model is to adopt such technical scheme to realize: it comprises housing, panel, housing is provided with air inlet, air outlet, air inlet communicates with the air channel, described air channel is respectively at being connected with breather valve with blower fan, described breather valve is connected successively with flow transducer, pressure transducer and air outlet, it is characterized in that being provided with in the air inlet filter course, be provided with dividing plate in the described air channel, on the described blower fan air-permeating hole is arranged, described panel is connected with breather valve, flow transducer, pressure transducer electricity respectively.
Compared with prior art, air, is removed dust and can be reduced harmful ignorant such as dust and enter in the respirator air channel by filter course from air inlet.The dividing plate that is provided with in the air channel limpens the air channel, helps reducing the noise of breathing in the handoff procedure.The air that enters the air channel enters breather valve after by the blower fan pressurization, and panel is according to breathing state, and the control breathing valve makes gas backstreaming by valve to fans entrance, significantly reduces noise, and air reaches air outlet after by pressure transducer.There is air-permeating hole the blower housing side, and internal gas is discharged by the hole, is used to cool off panel, reduces the temperature of each element in the panel greatly.The machine of ensuring respiration has good working environment.Adopt panel be core in conjunction with pressure transducer, flow transducer, breather valve and blower fan, can reach the Synchronization Control purpose of respirator well according to the state of flow and pressure signal control blower fan and valve.
