Description

Act on the respirator of pleural space and the method for its ventilation

Technical field: the present invention relates to a kind of respirator and its vent method, particularly relate to a kind of respirator of pleural space and method of its ventilation of acting on.

Background

The mechanical respirator of current application is in the world nearly hundreds of, from simple pneumatic level pressure type mechanical respirator, to the multi-function ventilator that electronic computer and various auxiliary facilities are housed.Domestic conventionally clinically also have tens of kinds more than.The design of these mechanical respirators, structure, operational approach etc. are all different, in any case but complicated respirator, it is poor that operation principle is all to set up an atmosphere-alveolar pressure, reaches the ventilation of lung.By the position classification respirator that conventionally acts on body, be broadly divided into:

(1) thorax pressurization (external formula respirator: Drinker respirator, cuirass formula, belt.)

Patient's thorax or whole health are placed in to (except head) in hermetic container, and respiratory tract opening communicates with atmosphere, alternately changes the pressure in container, when pressure is during lower than atmospheric pressure, thorax and lung are pulled expansion, and alveolar pressure is lower than atmospheric pressure, air enters lung, produces air-breathing; When container inner pressure is just becoming, thorax pressurized dwindles, and alveolar gas excretes, and produces and exhales.Because wanting the shortcomings such as demanded driving force is large, volume is stupid, ventilatory effect is poor, now eliminating need not.

(2) every nerve or every flesh stimulator

Electricity irritation phrenic nerves or every flesh → every flesh contraction → intrathoracic pressure reduction → alveolar ectasia → air-breathing.Stop electricity irritation → every flesh recovery → intrathoracic pressure recovery → elastance of lung retraction → exhale.Still in test, effect is difficult to certainly this method,

(3) through respiratory tract direct weighting

Through respiratory tract direct weighting, be with gas, directly to apply normal pressure at respiratory tract opening, surpass alveolar and press and produce pressure differential, gas enters lung → air-breathing; Release pressure, alveolar is pressed higher than atmospheric pressure, and alveolar gas excretes → exhales.Clinical respirator used all carries out work by this way now.Negative pressure ventilation while substituting autonomous respiration due to it with malleation, cause that air flue is intrinsic pressure, the waveform of alveolar pressure, intrathoracic pressure is completely different from autonomous respiration, mode of operation and the interior environment of each tract of body have almost been changed, be embodied in: 1. due to the use of face shield, nasal mask, laryngeal mask, tracheal intubation, cause patient to lose autonomic activities power, verbal communication power, oral feeding power, increased the risk of skin injury, laryngeal edema, air flue mucosa injury, respiratory tract pollution, sinusitis, aspiration pneumonitis, stomach inflation etc.; 2. due to the rising of intrathoracic pressure, the natural law that while having reversed autonomous respiration completely, the hematodinamics cycle changes, causes the interior environment change of the main organs work such as the heart, lung, brain, kidney, liver; 3. due to the increasing of alveolar pressure, increased alveolar dead space, increased alveolar overdistension and the risk of windage occurs; 4. inharmonious due to patient's fear, people-machine, has increased muscle relaxant, ataractic use, quadruped locomotion funtion part or total loss.In a word, through the ventilation of respiratory tract direct weighting, be to change body normal physiological 26S Proteasome Structure and Function, cause the mechanical ventilation mode that the forfeiture of body partial function and the disorder of interior environment are cost.

For overcome through respiratory tract direct weighting respirator to upper respiratory tract occupy, function is cracked and to deficiencies such as the disturbance of organismic internal environment, reversions, the invention provides a kind of by changing pleural space internal volume and (or) pressure, then change alveolar pressure, reach respirator and its vent method auxiliary or positive mechanical ventilation object.

Operation principle is: with the open bilateral pleural space of pleural space intubate, with patient end sensor or diaphragm muscle pyroelectric monitor instrument monitoring patient autonomous respiration, in the synchronous or asynchronous mode of gas dynamic system periodically to gas injection in pleural space or bleed, to change pleural space internal volume and pressure, indirectly change alveolar pressure, produce atmospheric pressure-alveolar poor, reach object auxiliary or positive mechanical ventilation.When patient has autonomous respiration, when patient exhales, respiratory muscle is lax, and intrapleural pressure power raises, and lung bounces back under the effect of elastical retraction power, now, to gas injection in pleural space, assist or strengthen the elastical retraction ability of lung, rising alveolar pressure, make alveolar pressure be greater than atmospheric pressure, reach auxiliary and exhale; When patient is air-breathing, respiratory muscle shrinks, pleural pressure reduces, and the pulling force of negative pressure is greater than the elastical retraction power of lung, and lung starts to expand, now, while extracting expiration out, to the gas of Intrapleural injection, strengthen the negative pressure pulling force in pleural space, reduce alveolar pressure, make atmospheric pressure be greater than alveolar pressure, reach auxiliary air-breathing.When patient's autonomous respiration disappears, with standardize solution or level pressure, mode regularly, to gas injection in pleural space, intrapleural pressure is increased, and thoracic expansion, diaphram move down, lungs bounce backs, and alveolar pressure raises, and alveolar pressure is greater than atmospheric pressure, completes and forces expiration; With standardize solution or level pressure, mode regularly, extract out while exhaling to the gas of Intrapleural injection, intrapleural pressure reduces again, and moves, lungs expand on thorax retraction, diaphram, and alveolar pressure reduces, and atmospheric pressure is greater than alveolar pressure, complete force air-breathing.While no matter having autonomous respiration or autonomous respiration to disappear, all can coordinate or the independent diaphram myoelectricity pace-making ventilating mode that uses.
