Abstract

A kind of air bag expansion formula trachea cannula, including hard tube, hose and cuff, the junction of hard tube side wall is fixed with seal wire, seal wire lower end extends to hose side wall bottom end, hose top is docked with hard tube, and hose tube wall is respectively hose inner wall, inflated supporting layer and hose outer wall from inside to outside, and inflated supporting layer is made of the cross-shaped support body of several air-tight connections, hose lower end is socketed with cuff, and being tightly connected on the inside of cuff has sleeve bag gas-filling pipe.Diameter is small before hose is inflated, and more narrow glottis and air flue can be inserted into seal wire, suitable for the patient of difficult intubation, reduces and implements tracheotomy；Hose inner wall and hose outer wall can carry out effective protection, on the one hand cross-shaped support body facilitates injection air, struts hose rapidly, on the other hand, are not easy to reverse after strutting, deform；In addition, the utility model can effectively reduce the damage for implementing endotracheal intubation to patient oral cavity, epiglottis, tracheae etc..

Description

A kind of air bag expansion formula trachea cannula

Technical field

The utility model belongs to medical treatment consumptive materials field, and in particular to a kind of air bag expansion formula trachea cannula.

Background technique

Endotracheal intubation is arranged for clinical anesthesia, CPR and rescue with the critical patient of respiratory dysfunction It applies, is a kind of quickly and effectively first aid means, in medical aid, application is extremely wide.Trachea cannula is as endotracheal intubation Main consumptive material, quality and reliability be directly related to the life and health of patient, traditional trachea cannula be hard or band plus The long tube of strong silk, it is indeformable in ventilation to guarantee pipeline, however, having the gas such as wound, scar contracture or tumour when encountering air flue When the narrow situation in road, trachea cannula is difficult to by position needed for arriving at airway constriction, to influence the treatment of patient, even Threat to life.And generally require to replace small-bore tracheal catheter at this time or implement tracheotomy, tracheotomy is for sufferer It is more painful, and it is big to nurse difficulty；The ventilation of osculum diametered duct is often insufficient, is not able to satisfy the oxygen of patient for demand, ultimately causes Patient's oxygen is for deficiency, carbon dioxide accumulation, threat to life.

Summary of the invention

In view of the deficienciess of the prior art, the utility model provides a kind of gas for first inserting back brace, intubation easy to implement Capsule expanding trachea cannula.

The utility model is achieved through the following technical solutions:

The junction of a kind of air bag expansion formula trachea cannula, including hard tube, hose and cuff, the hard tube side wall is fixed with Seal wire, the seal wire lower end extend to hose side wall bottom end, and the hose top is docked with the hard tube, the hose pipe Wall is respectively from inside to outside hose inner wall, inflated supporting layer and hose outer wall, and the inflated supporting layer is by several air-tight connections Cross-shaped support body composition, the cross-shaped support body of upper end has and only one end air-tight connection has support and inflation pipe, the hose Lower end is socketed with the cuff, and being tightly connected on the inside of the cuff has sleeve bag gas-filling pipe, and the sleeve bag gas-filling pipe is threaded through described Between hose inner wall and the hose outer wall, the support and inflation pipe and sleeve bag gas-filling tube top end are separately installed with instruction ball The air inlet of capsule, the instruction sacculus is equipped with check valve.

The hose bottom beveling, and it is provided with side gas vent.

The hard tube top is socketed with machine end connector.

Compared with prior art, the utility model has the beneficial effects that the utility model uses inflatable hose design, Implement intubation before inflation, since hose diameter is small, more narrow glottis and air flue can be inserted into seal wire, is strutted again after insertion Pipeline is formed, suitable for the patient of airway constriction, and effectively reduces implementation tracheotomy, reduces the injury to patient body； Hose uses three-decker, and hose inner wall and hose outer wall can carry out effective protection, on the one hand cross-shaped support body facilitates injection empty Gas struts rapidly hose, on the other hand, after strutting forms reliable support, is not easy to reverse, deform；In addition, the utility model energy The damage for implementing endotracheal intubation to patient oral cavity, epiglottis, tracheae etc. is effectively reduced, the pain of patient is reduced.

Specific embodiment

A kind of air bag expansion formula trachea cannula as shown in Fig. 1 to Fig. 4 in Figure of description, including hard tube 1,2 and of hose Cuff 3, the junction of 1 side wall of hard tube are fixed with seal wire 4, and 4 lower end of seal wire extends to 2 side wall bottom end of hose, 2 top of hose and hard Pipe 1 dock, 2 tube wall of hose from inside to outside be respectively hose inner wall 5, inflated supporting layer 6 and hose outer wall 7, inflated supporting layer 6 by The cross-shaped support body 8 of several air-tight connections forms, and the cross-shaped support body 8 of upper end has and only one end air-tight connection has support and inflation Pipe 9,2 lower end of hose are socketed with cuff 3, and being tightly connected on the inside of cuff 3 has sleeve bag gas-filling pipe 10, and sleeve bag gas-filling pipe 10 is threaded through soft Between inside pipe wall 5 and hose outer wall 7, support and inflation pipe 9 and 10 top of sleeve bag gas-filling pipe are connected separately with instruction sacculus 11, instruction The air inlet of sacculus 11 is equipped with check valve.

When implementing endotracheal intubation, 1 one end of hard tube should be held, patient's gas is inserted into 2 bottom end of hose of unaerated state Then position needed for managing runs through support and inflation pipe 9 and inflates to cross-shaped support body 8, hose 2 is propped up, finally passes through set again Capsule gas tube 10 is inflated to cuff 3, and passes through the instruction judgement inflation completeness of sacculus 11 respectively.

The beveling of 2 bottom of hose, and it is provided with side gas vent 12, it prevents 2 bottom primary outlet of hose from blocking, can not supply oxygen.

1 top of hard tube is socketed with machine end connector 13, to connect breathing machine.

In conclusion the preferred embodiment of only the utility model, is not used to limit the utility model implementation Range, all equivalent changes according to carried out by shape described in the utility model claims range, construction, feature and spirit with repair Decorations, should be included in the scope of the claims of the utility model.
