Description
Technical field
The utility model is related to a kind of sputum elimination machine, especially a kind of expectoration that can not affect lung ventilator to run in expectoration
Machine.The utility model further relates to the suction sputum module for the sputum elimination machine.
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 trachea cannula or by modes such as tracheotomies
The mechanical ventilation of vertical artificial airway.Urgent patient is set up after artificial airway, and the cough reflex 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 urgent 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 lung ventilator 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 is multistage up to 20, using sputum aspirator tube, can only inhale the sputum in main airway.It is additionally, due to lung and asymmetric, inhale
Phlegm pipe can only be drawn onto the phlegm of that side of right lung, the phlegm 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 bacterium, haemodynamics.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 phlegm in deep.
But need during due to using disconnect lung ventilator, troublesome poeration and disconnect lung ventilator 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 PCT International Patent Application of publication number W02007/054829A2, discloses a kind of mechanical air intake and exhaust system,
It by lung ventilator suction airflow, therewith quickly, very brief ground exhaled gas cough simulating human body, make alluvial in air flue and tracheae
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 bronchuses are had influence on, phlegm 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 lung ventilator 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) suction sputum, the complex structure of collection phlegm, are easy in pipeline
Attachment sputum, and it is unfavorable for cleaning；5) suction sputum effect is poor, and improving suction sputum effect by adjusting negative pressure can produce to patient
Life is adversely impacted.

Second switch valve 11 is closed, and pneumatic operated valve 2 is in open mode.Air bag 10 is charged the gas of proper volume.Breathing
Machine gives Patients with Mechanical Ventilation by pneumatic operated valve 2, first sensor 1, the first extension tube 3.After expectoration is started, expiratory phase, the
One switch valve 8 and second switch valve 11 are closed, and pneumatic operated valve 2 is in open mode, and lung ventilator is to patient's positive airway pressure；
After air-breathing terminates, pneumatic operated valve 2 is first shut off, and after patient's breath holding time terminates, second switch valve 11 is opened, in air bag 10
Gas is discharged through the expiration arm of lung ventilator, and simultaneously, first switch valve 8 is opened, and passes through the negative pressure that negative pressure source 9 is produced
Negative-pressure suction pipeline 5 and suction sputum module 4 are applied to patient airway, and cough is simulated with this, realize expectoration.
Sputum elimination machine of the present utility model can coordinate corresponding Use of respirator, as shown in figure 5, one reality of the utility model
The application schematic diagram of the sputum elimination machine of example is applied, i.e., is used in combination with lung ventilator, a respirator system is constituted, by gas compensation module
The expiration arm of lung ventilator is connected to, and suction sputum module is connected to into breathing pipeline near patient one end or is directly connected in artificial
Air flue.
Suction sputum module for sputum elimination machine of the present utility model, can be used for corresponding sputum elimination machine, by negative pressure expectoration interface
The negative port of negative pressure source of the gas is connected to, the left port of four-way pipe fitting is connected to into breathing pipeline near patient one end or is directly connected
Artificial airway is connected to, and connects phlegm liquit collector in sputum collecting interface, then by right output port closing, whereby can the row of execution
Phlegm is operated, can with the gap of expectoration to clearing up in pipeline, it is to avoid the attachment of sputum affects suction sputum effect.
In sum, sputum elimination machine of the present utility model, due to the design of suction sputum module so as to can by expectoration pipeline with exhale
Suction pipe road is completely separated, and the sputum for fundamentally reducing discharge pollutes the probability of breathing pipeline, further, due in suction sputum
Four-way pipe fitting is provided with module so that by simple structure, acquirement can either provide sputum elimination machine suction sputum, phlegm can be collected again
Liquid, and the effect of the attachment sputum being convenient to clean in pipeline, also, because gas compensation module can be in expectoration to lung ventilator
Expiration end compensating gas, it is to avoid produce when lung ventilator can't detect gas and report to the police or change running parameter, not shadow when accomplishing expectoration
Ring lung ventilator operation.
