Description
Technical field
This utility model is related to a kind of pneumatic operated valve, especially a kind of diaphragm valve.This utility model further relates to have the diaphragm
The sputum elimination machine of valve.
Background technology
Clinically there is some or all of forfeiture autonomous respiration ability of many patients, medical personnel can be as the case may be
They provide no-wound mechanical ventilation or Mechanical ventilation, help patient to maintain breath cycle with this, improve oxygen conjunction and recover
Effectively autonomous respiration.Wherein Invasive vent ilation is referred to need to be built by oral or nasal tracheal intubation or by modes such as tracheotomies
The mechanical ventilation of vertical artificial airway.Critical patient is set up after artificial airway, and the coughre flex of itself weakens, and upper respiratory tract heating adds
Wet function is deprived of, and cilium self-cleaning action weakens, and airway secretions increase, and clearing pneogaster is to ensure that effective mechanical ventilation is controlled
Treat, save one of key factor of critical patient.
Conventional suction sputum method clinical at present is closed sputum aspirator suction sputum.Closed endotracheal suction refers to and is not required to disengage respirator or stopping
The suction sputum operation of mechanical ventilation, and hyaline membrane is cased with outside sputum aspirator tube, whole suction sputum process is completed in the case of closed.
Intrapulmonary bronchus are multistage up to 20, using sputum aspirator tube, can only inhale the sputum in main airway.It is additionally, due to pulmonary and asymmetric, inhale
Expectorant pipe can only be drawn onto the expectorant of that side of right lung, the expectorant of left lung side then inhale less than.Mechanical ventilationassociatepneumonia pneumonia is multiple in left lung, just there is this
Individual reason.
Using sputum aspirator tube suction sputum, the impact equivalent risk also scratch with air flue, brought in antibacterial, hemodynamics.Except
This manual sputum aspirator of closed sputum aspirator, also there is automatic expectoration device now.The Cough of PHILIPS Co.'s production
Assist expectoration machines, principle is that fast transition is negative inspiratory pressure to after the once larger positive airway pressure of air flue offer, by simulation
Cough air-flow further suctions out the expectorant in deep.
But need during due to using disconnect respirator, troublesome poeration and disconnect respirator have great risk to patient with severe symptoms,
Cannot be used as regular expectoration means；Controlled quentity controlled variable of the Cough Assist expectorations machines using the time as loop cycle, is come with this
Terminate breathing process, but it is safer and more effective as the controlled quentity controlled variable of loop cycle using capacity or flow.In addition, Cough Assist
The positive end expiratory pressure (PEEP) of patient cannot be kept, for needing the patient of high PEEP not apply to, these patients are without height
PEEP has the risk of alveolar collapse；Another distinct disadvantage is that Cough Assist do not include should be had in life-support system
Warning system；Finally, it only has a pipeline, exhales and air-breathing is shared, may dividing last time expectoration during next air-breathing
Secretion is sucked, it will increase the superinfection risk of patient oneself, it may also reduce the pipeline life-span, while also can increase using next time
The infection risk of the patient of the machine.
In addition, the international patent application of publication number W02007/054829A2PCT, discloses a kind of mechanical air intake and exhaust system,
It by respirator suction airflow, therewith quickly, very brief ground exhaled gas cough simulating human body, make alluvial in air flue and trachea
Sputum in branch is smoothly discharged.This system automatically controls air-breathing and expiration by detecting air-flow, alleviates staff's
Burden.By the continuously negative pressure expiration expectoration sputum of discontinuity several times, both prevented that negative pressure is excessive to cause alveolar collapse, Er Qieneng
Ten what bronchus are had influence on, expectorant is discharged from the deep of lung.But still there are some defects in this equipment：1) without solution
The sputum that certainly expectoration comes pollutes the problem of breathing pipeline；2) in use, due to closing respirator expiration pipeline, easily make
Into ventilator alarm, medical personnel are also easily made to cause to misread, worry；3) suction pipeline does not have air flue safety adjustable-pressure device, no
The negative pressure for producing can be accurately controlled, the too high risk of negative pressure is also occurred；4) its breathing pipeline is by the electromagnetism in respirator
Valve arranges if desired from the closer position of people come what is controlled, such as near patient one end, then can adversely affect.

Respirator gives Patients with Mechanical Ventilation by air-operated diaphragm valve 2, first sensor 1, the first extension tube 3.After expectoration is started, air-breathing
Stage, first switch valve 8 and second switch valve 11 are closed, and air-operated diaphragm valve 2 is in open mode, and respirator is to suffering from
Person's positive airway pressure；After air-breathing terminates, air-operated diaphragm valve 2 is first shut off, after patient's breath holding time terminates, second switch valve 11
Open, the gas in air bag 10 is discharged through the expiration arm of respirator, and simultaneously, first switch valve 8 is opened, and makes negative pressure source
9 negative pressure for producing are applied to patient airway by negative-pressure suction pipeline 5 and suction sputum module 4, and cough is simulated with this, the row of realization
Expectorant.
Sputum elimination machine of the present utility model can coordinate corresponding Use of respirator, and gas compensation module is connected to into respirator
Expiration arm, and suction sputum module is connected to into breathing pipeline near patient one end or artificial airway is directly connected in.
Air-operated diaphragm valve for sputum elimination machine of the present utility model, can be used for corresponding sputum elimination machine, can in expectoration,
The negative pressure that respirator is produced with expectoration machine is kept apart, it is to avoid：1. respirator is detected and trigger after negative pressure positive airway pressure, is offset negative
The effect of pressure suction sputum；2. ventilator alarm or damage are caused because negative pressure is excessive.
In sum, sputum elimination machine of the present utility model, because it is completely separated expectoration pipeline and breathing pipeline, from basic
On reduce the sputum of discharge and pollute the probability of breathing pipeline, also, due to, to respirator expiration end compensating gas, keeping away during expectoration
Exempt to be produced when respirator can't detect gas and report to the police or change running parameter, do not affect respirator to run when accomplishing expectoration.
