General oral cavity suction sputum, can only attract the phlegm at oral cavity and epiglottis.Endotracheal suction (ets) can only also attract main tracheae and portion Branch's tracheae.Bronchofiberscope bronchus suction sputum can only also attract 3,4 grades of big bronchus, just more tired to smaller bronchus suction sputum Difficulty, and damage is also more big, can aggravate to infect, so the use of Bronchofiberscope is limited；Also, Bronchofiberscope will be many The bronchus that infection is found in bronchus is very difficult, this just requires healthcare practitioner very high；The cost of use of Bronchofiberscope is very It is high；General medical institutions use and skillfully using the seldom of Bronchofiberscope.

Normal person can cough, expectoration.Cough is one of most common symptom of respiratory disease, it is that human body removing is exhaled The protectiveness respiration reflex action of the secretion or foreign matter in road is inhaled, expiration percussion action is generated by cough, can will be breathed Foreign matter or secretion in road excrete.

The power of cough is that intrathoracic pressure and intra-abdominal pressure increase, in addition Closure states of glottis, stays entire pressure There are in thoracic cavity.When glottis card is opened, the gas of intrapulmonary can quickly flow out at glottis,

When gas passes through glottis, the vocal cords of glottis is driven to swing, vocal cords is made to generate vibrations, vibrations generate sound, vocal cords Vibrations be transmitted to annular cartilage, entire annular cartilage is made to generate resonance,

Since annular cartilage vibrations drive the vibrations of entire throat, the vibrations of throat are transmitted to surrounding, wherein downward tracheae with Throat connects, and entire tracheae generates resonance with throat, and entire tracheae generates vibrations and is transmitted to lung again, and entire lung is made to generate altogether It shakes.

When tracheae shakes, form small gap between the foreign matter on tracheae surface and tracheae surface, it is this it is small between Gap can make the secretion on tracheae surface（Foreign matter）Adhesion strength between tracheae surface substantially reduces.

When the secretion on tracheae surface（Foreign matter）When adhesion strength between tracheae surface substantially reduces, tracheal strips have at this time To the air-flow of outflow, air-flow can push the foreign matter of tracheae to elapse outward, and one or many resonance are until by secretion（Foreign matter）Cough Air outlet pipe reaches throat, after reaching throat, passes through the closing of epiglottis, the extruding of throat, the negative pressure in oral cavity, between tongue body and maxilla Gap etc., make the secretion of throat（Foreign matter or secretion）It concentrates between tongue body and maxilla.Again by primary simple Air-flow is by intraoral secretion（Or foreign matter）Discharge oral cavity.Complete the process of entire expectoration.

When the respiratory system of human body is infected by pathogeny bacterium, germ and sputum in respiratory tract can be arranged by cough Go out external.When such as suffering from tracheitis, pneumonia disease, respiratory tract can have a large amount of sputums up and down, if powerless because coughing, cough stops Only or it cannot cough, phlegm will be left in respiratory tract at this time, and phlegm is good culture medium, can make bacterium, viral amount reproduction, Spread inflammation；If secretion delays the breeding for promoting bacterium in respiratory tract, make increased inflammation；And secretion delays meeting Increase the resistance of respiratory tract, can also block trachea-bronchial epithelial cell or bronchiole, lung tissue be caused to collapse, local lung function It loses, if continued, lung can more collapse successively, can finally cause respiratory failure, jeopardize or life.

Some the elderlys suffer from the patient of chronic bronchitis, have arrived the later stage of chronic bronchitis, he（She）Old body It is weak, it often coughs powerless.The original secretion in respiratory tract surface is tiling and is dispersed in multiple tracheal strips, respiratory secretions Meeting irritative cough, and it is powerless to cough, one, cough, the secretion on tracheae surface does not move at all.Both limited body had been consumed Power, and without effect.Two.It coughs, the secretion secretion on tracheae surface moves, but cough does not come out.Tiling tracheae surface Secretion can form ball-type aggregation, reduce or block air flue space.One or more levels upward tracheae of the secretion of multiple air flues Interior aggregation reduces or blocks one or more levels air flue space upwards and the respiratory failure aggravated.

Severe is gone into a coma, brain trauma, and self-protection ability declines, cough reduced capability or forfeiture.And some are closed And accidentally inhale, need suction sputum and cough, Advanced Life support upper lung ventilator patient he（She）Cannot oneself cough, operation With the patient of anesthesia he（She）Cannot cough, in addition in the thoracic cavity normally coughed and the pressure of intra-abdominal pressure be to increase , the wound that repeated coughing can make the wound of suture or heal splits again, especially the wound of abdomen.In addition, Postoperative band tracheal respiration, it is simple with sputum aspirator tube in endotracheal suction (ets), phlegm is blown to main tracheae by the powerful air-flow of the generation of patient In interior and feed channel pipe, then the phlegm blown out is drawn with sputum aspirator tube.This suction sputum mode stimulate it is very big, patient it is emergent also very Greatly, it is very big, and be breakneck to patient's harm.

Step 2, it is inflated into inflating pressure suit, squeezes chest, back, the abdomen of the patient for being inflated pressurization suit package Portion and waist.

In this step, indirectly increase intra-abdominal pressure and intrathoracic pressure, finally make the pressure of intrapulmonary higher than the pressure outside air flue By force；When open airway, the gas of intrapulmonary quickly flows out intrapulmonary air flue by larger pressure difference.

Step 3, it is positioned over the vibration component vibration at patient's os presternum and drives the tracheae of patient and lung's vibration,

In this step, make the secretion of the airway surface of intrapulmonary（Foreign matter）Adhesion strength between tracheae surface drops significantly It is low.

When the secretion on tracheae surface（Foreign matter）When adhesion strength between tracheae surface substantially reduces, tracheal strips have at this time Quickly the air-flow of outflow intrapulmonary, air-flow can push the secretion of tracheae to elapse outward, one or many until by secretion（It is different Object）The tracheae of cough to bigger reaches throat, can facilitate attraction or direct expectoration.

The above is only the preferred embodiment of the utility model only, is not intended to limit the utility model, all at this All any modification, equivalent and improvement made within the spirit and principle of utility model etc., should be included in the utility model Protection domain within.
