Description
Technical field
Medical instruments field is the utility model is related to, more specifically, it is proposed that a kind of lung ventilator.
Background technology
Cough is the protectiveness respiration reflex action that human body removes secretion or foreign matter in respiratory tract, and he and breathing are deep
Breathing etc. is the same, is the normal physiological requirements of human respiratory.But for the disease of respiratory failure caused by a variety of causes
People, not only normal breathing is into a luxurious thing, let alone coughs and deeply breathe.Gratified is now with breathing
Machine, can not only meet this kind of clinical and patient in family respiratory demand, and the lung ventilator of middle and high end even can help patient to carry out
Deeply breathe (i.e. the sigh function of lung ventilator), still, at present, the cough of patient is also simulated without a breathing function.
Patent CN204910377 proposes one kind turbine and produces negative-pressure air-flow, coordinates the bionical row of diaphram electromagnetic stimulation
Phlegm mode.But the mode shortcoming of this bionical expectoration is undoubtedly obvious：First, utility model person proposes to use nerve stimulation
Mode, make respiratory muscle produce specific action, be engaged with respiratory air flow.It is to have subjective will but people is not equal to machine
And the complicated animal of individual physical difference, to the nerve of patient using it is electric magnetically or mechanically by the way of stimulate, people produces therewith
Reaction be unpredictable：Such as a few minutes in evening or early several seconds produce and acted expected from utility model person, or and utility model
The expected action of person opposite (producing aspiratory action when expiration action is produced during air-breathing, being exhaled) is not reacted at all.This is all
The action for making utility model person's imagination and function are lost to the possibility to go on！In order to complete the automatic of utility model person's imagination
Change, allow the patient to live to deacclimatize, follow the beat of ice-cold machine, physiological function is firmly raw to want grafting mechanical automation, it is clear that
It is impossible.Always really valuable, strong innovation medicine equipment is all based on care to people and to people's
It is passive to coordinate and adapt to, rather than conversely.Meanwhile often cough once, an electromagnetic stimulation will be carried out to patient, patient is nervous
It is and painful.Secondly, the patent propose to be realized to the mechanical ventilation of patient with positive airway pressure module and negative pressure ventilation module respectively and
Expectoration.It is complicated, cost is too high.3rd, the patent has lacked expiration module, therefore can not meet clinically PEEP treatments disease
Man's Demands.4th, the patient of invasive breathing can not be used in.The 5th, even if this electromagnetic stimulation is feasible, but in Clinical practice
When, the normal work of other cardiac monitoring equipment that must be used can be also influenceed, or even cause to damage, if pierced using electromagnetism
Swash, must just withdraw cardiac monitoring equipment simultaneously, this is especially at all unworkable in ICU wards.6th, for myasthenia
Patient, even if electromagnetic stimulation can not make muscle become strong, therefore actually use in may fall flat.
