Wherein, the intubation joint is a conical joint with the diameter of 15 mm.

The intubation tube body and the collection tube body are connected in a glue bonding or fixing piece mode.

Wherein, gather body end and extend to the near end mouth inboard of intubate body.

Wherein, the cannula body proximal end includes a plurality of supplementary air vents.

According to the utility model discloses a trachea cannula with gaseous sampling function, it can be to patient's intubate, when establishing the oxygen suppliment of artificial respiration passageway, be connected with the outside equipment that has carbon dioxide monitor function through gathering the pipe, sample, monitor and analysis patient end-expiratory carbon dioxide, make medical personnel when maintaining patient breathing unobstructed, can continuously monitor the situation of patient's lung function, provide clear and definite index for patient breathes support and breathe the management. Has the characteristics of convenient use, simple operation and high safety.

Drawings

The accompanying drawings, which are included to provide a further understanding of the invention and are incorporated in and constitute a part of this application, illustrate embodiment(s) of the invention and together with the description serve to explain the invention without undue limitation to the invention. In the drawings:

fig. 1 is a schematic view of an endotracheal tube having a gas sampling function according to an embodiment of the present invention.

Detailed Description

To make the purpose, technical solution and advantages of the present invention clearer, the following will combine the embodiments of the present invention and the corresponding drawings to clearly and completely describe the technical solution of the present invention. It is to be understood that the embodiments described are only some embodiments of the invention, and not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

The technical solutions provided by the embodiments of the present invention are described in detail below with reference to the accompanying drawings.

According to the embodiment of the utility model provides a pair of trachea cannula with gaseous sampling function, it is through the oral cavity or intranasal intubate, when establishing artificial respiration passageway oxygen suppliment, is connected with the outside equipment that has carbon dioxide monitor function through gathering the pipe, samples, monitors and the analysis patient end-tidal carbon dioxide.

Referring to fig. 1, the endotracheal tube includes a tube body 1, the tube body 1 may be straight or curved, and the tube body 1 includes a proximal end 2 and a distal end 3. The proximal end 2 of the cannula tube 1 can also be called a patient end and is one end inserted into the oral cavity or nasal cavity of a patient, and the proximal end 2 of the cannula tube comprises an inclined plane with an inclined plane angle alpha of 20-50 degrees.

The distal end 3 of the cannula body 1, which may also be referred to as the mechanical end, comprises a cannula adaptor 4, said cannula adaptor 4 being a 15mm conical adaptor. The intubation joint 4 can be connected with a pipeline of a breathing machine or an anesthesia machine to supply oxygen for a patient.

Continuing to refer to fig. 1, the intubation tube body 1 is connected with a collection tube body 5, and the collection tube body 5 may also be called a gas collection tube or a carbon dioxide collection tube, wherein the tube diameter of the collection tube body 5 is smaller than that of the intubation tube body 1. The collecting pipe body 5 is connected with a luer connector 6 and a filter 7, and the collecting pipe can be connected with equipment with a carbon dioxide monitoring function through the luer connector and an extension pipe on the filter 7 to sample, monitor and analyze the end-tidal carbon dioxide of the patient.

In this application embodiment, gather body 5 and intubate body 1 and be connected through the mode of glue bonding or mounting, this application does not prescribe a limit to the connected position of intubate body 1 and collection body 5, gathers body 5 and intubate body 1 and is connected the back, and the end of gathering body 5 extends to 2 mouth inboards of the near-end of intubate body 1, and 2 departments of intubate body 1 near-end can be including a plurality of supplementary air vents.

In conclusion, after the trachea cannula is inserted through the mouth or the nose, the pipeline of a breathing machine or an anesthesia machine is connected with the cannula joint for ventilation and oxygen supply, and meanwhile, the collecting tube can be connected to equipment with a carbon dioxide monitoring function to sample, monitor and analyze the end-tidal carbon dioxide of a patient. The medical staff can continuously monitor the lung function of the patient while maintaining the smooth breathing of the patient, and clear indexes are provided for the breathing support and the breathing management of the patient. Has the characteristics of convenient use, simple operation and high safety.

The above description is only an example of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the scope of the claims of the present invention.
