Description

The cannula type breathing apparatus

This utility model relates to medical apparatus and instruments, especially for the respiratory organ that rescues the critical patient.

The development of modern medicine is had higher requirement to the salvage success rate of critical patient.In the heart, lung, cerebral resuscitation, the lung recovery is a ring of most critical, thereby more and more is subjected to domestic and international medical circle attention.A kind ofly collect life-kiss and the endotracheal intubation advantage is the emergency rescue breathing device of one, more successfully solved the effective first aid problem of on-the-spot breathing.It comprises breathing equipment: breathe under the ball and connect the oxygen supply valve body, on connect triple-valve body, the airway overcoat face shield of front end belt leather lobe is connected with the top of triple-valve body; Sputum aspirator: being linked to each other with negative pressure ball by the sputum aspirator tube that places the airway inner chamber constitutes.But this artificial ventilator also has defective: 1, because the flap of sealing esophagus links to each other with the end of airway, and airway and trachea touch for formula mouth to mouth, carried the mountain peak at the scene and winnow with a dustpan and influence, touch badly, influence and cure by oxygen therapy effect; 2, the three-way valve that is used to set up the oxygen therapy passage and the passage that gives off carbon dioxide is a metal valve, and breather cheek valve is that metal spring type, weight are big, easy-to-rust, cleaning difficulty; 3, the at the uniform velocity oxygen supply of breathing ball that links to each other with oxygen bottle, when needs were hurriedly breathed oxygen supply, the oxygen-supplying amount of unit interval was constant, can not be according to the oxygen-supplying amount of state of an illness needs in the variation unit interval; 4, the capacity of breathing ball is 800-900ml, and capacity is too little, and breathes the ball smooth in appearance, is difficult for during one-handed performance holding steadily.

The purpose of this utility model is to overcome above-mentioned defective, and a kind of practicality, reliable, health, the structure rational cannula type breathing apparatus that more becomes is provided.

Technical solution of the present utility model is: the cannula type breathing apparatus, comprise breathing equipment: order is to the air inlet valve body under the breathing ball, last connection air valve body, the airway overcoat face shield of anterior belt leather lobe is pegged graft with the top seal of ventilation valve body, and sputum aspirator is linked to each other with negative pressure ball by the sputum aspirator tube that places the airway inner chamber and constitutes; Airway with the flap connecting place before visit one section, visiting the section root before this has sputum suction hole near a side of flap.In the ventilation valve body the unidirectional ventilation flap valve of duck-beak type that silastic material is made is housed, a side is the expired gas body opening, and the bottom has and breathes the groove that ball is tightly connected.Breather cheek valve body top reaches for the air inlet flap valve and breathes the groove that the ball lower seal is connected, and the bottom is oxygen plug that links to each other with oxygen cylinder and the air plug that links to each other with the gas-storing bag that has unidirectional air inlet flap valve valve.

According to technique scheme, the patient lies on the back, and the hand-held blind spy posting port of airway inward turning turnback can arrive the glottis top; The airway leading portion inserts in the trachea, and simultaneously, it is suitable for reading that flap tightly is closed in esophagus.It is dirty both can to have prevented that air-flow from entering stomach, and anti-stream of retardance stomach Dissolve things inside.Hold negative pressure ball, insert endotracheal port by sputum aspirator tube, but the sucking-off intra-tracheal sputum; Remove esophageal orifice by spy section root before the airway near the sputum suction hole of flap one side and reach endotracheal sputum on every side.Breathe the endoceliac oxygen of ball bottom breather cheek valve, air, when the breathing ball is negative pressure, enter the breathing ball by the air inlet flap valve; When the breathing ball was malleation, air inlet flap valve pressurized was closed, and the intravital duck of breather valve chews the unidirectional ventilation flap valve of formula and opened by positive pressure, and valve body is suitable for reading to be entered in patient's trachea oxygen by airway through ventilating; The patient gives off carbon dioxide after inhaling an oxygen immediately, and breathe ball be in negative pressure state this moment, and duck chews that the unidirectional ventilation flap valve of formula is closed and to lower recess, make airway, breather valve intracoelomic cavity and venthole form carbon dioxide exhalation passage.After the oxygen of breather cheek valve intracoelomic cavity is sucked away, form negative pressure, the unidirectional air inlet flap valve valve on oxygen in the oxygen cylinder and gas-storing bag top enters air, replenishes rapidly.Oxygen cylinder is at the uniform velocity exported oxygen, and a part is stored in the gas-storing bag, when needs promptly strengthen the oxygen therapy amount, and the extruding gas-storing bag oxygen-supplying amount that can increase sharply.

Accompanying drawing 2 is this utility model gas-storing bag sketch map;

Accompanying drawing 3 is looked partial sectional view for this utility model ventilation valve body right side;

Accompanying drawing 4 is this utility model breather cheek valve body cutaway view.

In conjunction with the accompanying drawings, embodiment of the present utility model is described.

The anxious ball respiratory organ of cannula type comprises breathing equipment: breathe 8 times orders of ball to air inlet valve body 9, on connect air valve body 7, the airway 3 overcoat face shields 6 and the top seal of ventilation valve body 7 of anterior belt leather lobe 4 are pegged graft; Sputum aspirator is linked to each other with negative pressure ball 1 by the sputum aspirator tube 5 that places airway 3 inner chambers and constitutes; Airway meets normal human's upper respiratory tract dissect physiology characteristics by macromolecule medical grade silicon rubber material at high temperature die forming, airway 3 with flap 4 connecting places before visit one section, visiting the section root before this has sputum suction hole near a side of flap 4; It is expired gas body opening 2 that unidirectional ventilation flap valve 14, one sides of duck-beak type that silastic material makes are equipped with in ventilation in the valve body 7, and the bottom has and breathes the groove 15 that ball 8 is tightly connected.Breather cheek valve body 9 tops are air inlet flap valve 16, and the groove 17 that is connected with breathing ball 8 lower seal; The bottom is oxygen plug 10 that links to each other with oxygen cylinder and the air plug 11 that links to each other with the gas-storing bag 13 that has unidirectional air inlet flap valve valve 12.The breathing ball made from macromolecule medical grade rubber material 8 is oval cydariform, goes up flat edge with following flat center aperture and is complementary with
