Figures 1-3 show a prior art rigid bronchoscopic sheath made of medical grade stainless steel; it comprises an end seat 10 and a cannula body 20; the end seat 10 comprises a plurality of

channels

11, 12, 13, which allow the insertion of bronchoscopes, foreign body forceps, etc. in the case of connection to a ventilator, and also the infusion of drugs from the lateral channels. Wherein the passage 11 is a main passage formed on an extension of an axis of the tube body 20. The

channels

11, 12, 13 are of different diameters.

The tracheal cannula has the advantages that due to the arc-shaped bent structure, the tracheal cannula is convenient to insert into the airway of a subject, and cannot easily damage vocal cords; the tube body and the air passage are sealed by the air bag, so that air leakage is avoided; the disadvantages are that it is inconvenient to connect the ventilator to ventilate and perform other operations simultaneously and the image ventilation effect is not convenient, such as taking out foreign bodies.

The hard bronchoscope sheath has the advantages that the end seat is provided with a plurality of channels, and the bronchoscope and other tools, such as foreign body forceps, can be conveniently inserted or withdrawn under the condition of connecting a breathing machine; the disadvantage is that the insertion of a straight metal tube into the airway is difficult and the vocal cords are easily damaged when the tube passes through the glottis; in addition, a gap exists between the tube body and the air passage, so that air leakage is easy.

SUMMERY OF THE UTILITY MODEL

In view of the above problem, the present application aims to provide a tracheal cannula capable of being connected to a high-frequency ventilator, which has the advantages of a rigid bronchoscope sheath on the premise of maintaining the advantages of the tracheal cannula, and allows a bronchoscope and other tools to be inserted under the condition of being connected to the ventilator.

The trachea cannula capable of being connected with the high-frequency respirator comprises an end seat and a tube body; the end seat is integrally formed at the first end of the insertion pipe, the second end of the insertion pipe is provided with an air bag, the air bag is inflated and deflated through an inflation hose, and the end part of the inflation hose forms an inflation joint;

the end seat comprises a plurality of channels; the plurality of channels are all communicated with the interior of the tube body; one of the plurality of channels is for connection to a high frequency ventilator;

the end seat and the pipe body are made of plastics.

Preferably, a metal mesh is formed in the wall of at least one section of the pipe body to increase the rigidity of the pipe body; the metal mesh is disposed around the pipe body.

Preferably, the metal mesh is arranged at one end of the pipe body close to the end seat.

Preferably, at least some of the plurality of channels have different inner diameters.

Preferably, among the plurality of passages, the passage having the largest diameter is a main passage formed on an extension line of an axis of the pipe body.

The utility model provides a trachea cannula that can connect high frequency respirator on the basis of keeping current trachea cannula's basic structure, with the structure grafting of the end seat of current stereoplasm bronchoscope sheath pipe to current trachea cannula for the trachea cannula that can connect high frequency respirator of this application, can be open in the pipeline under the condition of connecting the respirator, conveniently carry out other intervention operations, for example the foreign matter takes out

Detailed Description

The following describes in detail an endotracheal tube to which a high frequency ventilator can be connected according to the present invention with reference to the accompanying drawings.

The trachea cannula capable of being connected with the high-frequency respirator comprises an end seat 10 and a tube body 20; the end seat 10 is integrally formed at a first end of the insertion tube 20, a balloon 31 is formed at a second end of the insertion tube 20, the balloon 31 is inflated and deflated through an inflation hose 32, and an inflation connector 33 is formed at an end of the inflation hose 32.

The end seat 10 comprises a plurality of channels; the plurality of passages are all communicated with the inside of the tube body 20; one of the plurality of channels is for connection to a high frequency ventilator.

The end seat and the pipe body are made of plastics, and the pipe body 20 has certain flexibility.

A metal mesh 40 is formed in the wall of at least one section of the pipe body 20; the metal mesh 40 is disposed around the pipe body 20 to increase the rigidity of the pipe body 20.

The metal mesh 40 is disposed at an end of the pipe body 20 near the end seat 10.

At least some of the plurality of channels have different inner diameters. Of the plurality of passages, the passage having the largest diameter is a main passage formed on an extension of the axis of the pipe body 20.

When the trachea cannula capable of being connected with the high-frequency respirator is used, the trachea cannula which can be connected with the high-frequency respirator is inserted into the airway of a subject like the trachea cannula in the prior art, then the air bag is inflated by utilizing the injector, and the gap between the airway and the tube body is sealed. A plurality of passageways on the end seat for the trachea cannula that can connect high frequency respirator of this application can carry out other operations through other passageways under the condition of connecting the respirator, utilizes to carry out the foreign matter under the bronchoscope and takes out.
