[0002] Endotracheal intubation is a common medical procedure used to provide respiratory support to patients in emergency situations. It is done by inserting a flexible tube into the patient's trachea to keep the airway open and allow the doctor to control the patient's breathing.

[0003] In the existing technology, the inclined surface of the endotracheal tube inserted into the patient's body is usually consistent with the hardness of the tube material. When the tube is inserted to the specified depth, it will cause abrasions to the patient, making it inconvenient to use. Utility Model Content

The bevel head is made of TPU material, and the bevel head material is soft, which prevents the patient's inner tube wall from being scratched during intubation; the sealing airbag is in a heart shape, which seals tightly and has a good sealing effect.

[0005] To achieve the above-mentioned objectives, the utility model provides the following technical solutions: a disposable reinforced endotracheal cannula, comprising a cannula body, one end of the cannula body being fixedly connected to a plug connector, a mating connector being plugged into the plug connector, a connecting connector being fixedly connected to the mating connector, an operating ear being fixedly connected to the connecting connector, a scale line being provided on the cannula body, an inflation tube being provided on the outside of the cannula body, an indicator airbag being fixedly connected to the outer end of the inflation tube, an inflation head being fixedly connected to the outer end of the indicator airbag, a one-way valve being provided on the inflation head, the other end of the cannula body being fixedly connected to a bevel head, a through hole being provided on the bevel head, a sealing airbag being fixedly connected to the side of the cannula body close to the bevel head, one end of the inflation tube extending into the cannula body and communicating with the sealing airbag, the bevel head being made of TPU material, and the sealing airbag being heart-shaped.

[0006] Furthermore, there are two operating ears, which are arranged axially symmetrically.

[0007] Furthermore, the through hole is elliptical in shape.

[0008] Furthermore, the sealing airbag is located on the left side of the scale line, and the plug connector is located on the right side of the scale line.

[0009] Furthermore, the radius of the inflation tube is smaller than the radius of the cannula body.

[0010] The utility model has the following beneficial effects:

[0011] The disposable reinforced endotracheal tube proposed by the utility model has a bevel head, and the bevel head part is made of TPU material. The bevel head material is soft, which prevents the patient's inner tube wall from being scratched during intubation; the sealing airbag is in a heart shape, which seals tightly and has a good sealing effect.

[0018] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0019] Reference Figures 1-4The utility model provides an embodiment of a disposable reinforced endotracheal cannula, comprising a cannula body 1, one end of the cannula body 1 is fixedly connected to a plug connector 3, a mating connector 4 is plugged into the plug connector 3, a connecting connector 5 is fixedly connected to the mating connector 4, an operating ear 501 is fixedly connected to the connecting connector 5, and there are two operating ears 501, which are axially symmetrically arranged. A scale line 2 is provided on the cannula body 1, an inflation tube 9 is provided on the outside of the cannula body 1, the radius of the inflation tube 9 is smaller than the radius of the cannula body 1, and an indicator air bag 8 is fixedly connected to the outer end of the inflation tube 9, which can be monitored by indicating the deflation or inflation of the air bag 8. The airbag 10 is fixedly connected to the outer end of the airbag 8 to see if it is in normal working condition. The airbag 6 is fixedly connected to the outer end of the airbag 8. The airbag 6 is provided with a one-way valve 7. The other end of the cannula body 1 is fixedly connected to a bevel head 101. The bevel head 101 is provided with a through hole 102. The shape of the through hole 102 is oval. The cannula body 1 is fixedly connected to the side of the bevel head 101 near the bevel head 101. The airbag 10 is located on the left side of the scale line 2, and the plug 3 is located on the right side of the scale line 2.
