Background technique

An artificial airway refers to a gas channel established when medical personnel insert a catheter into the trachea through the upper respiratory tract or directly into the trachea when the patient has difficulty breathing. It is an effective connection established between the physiological airway and the air or other gas sources to ensure the patency of the airway. It provides conditions for effective drainage, patency, mechanical ventilation, and treatment of lung diseases.

Specifically, the utility model provides an oxygen supply device for an artificial airway, which is made of soft polyvinyl chloride material, so that the oxygen supply device has a certain plasticity and softness. During clinical use, the angle of the oxygen supply tube 2 of the oxygen supply device can be adjusted at will, and the operation is convenient; the oxygen supply device includes an oxygen source connector 1, an oxygen supply tube 2, a connector 3 and an oxygen supply connector 4, the oxygen source connector 1 is a trumpet-shaped structure, the clamping end 11 of the oxygen source connector 1 is connected to the external oxygen supply system, the connecting end 12 is fixedly connected to one end of the oxygen supply tube 2, and the connecting head 4 is fixedly connected to the oxygen supply tube 2. The first top surface 31 of the connector 3 is connected to the other end of the oxygen supply tube 2, the first bottom surface 32 is connected to the second bottom surface 42 of the oxygen supply connector 4, and the second top surface 41 of the oxygen supply connector 4 is connected to the external artificial airway, so that the oxygen in the external oxygen supply system can enter the patient's artificial airway through the first oxygen supply channel inside the oxygen source connector 1, the second oxygen supply channel inside the oxygen supply tube 2, the third oxygen supply channel inside the connector 3, and the fourth oxygen supply channel inside the oxygen supply connector 4 in sequence to supply oxygen to the patient; the oxygen supply connector 4 is a truncated cone structure, and the first bottom surface 32 of the oxygen supply connector 4 is connected to the second bottom surface 42 of the oxygen supply connector 4. The second top surface 41 of the oxygen supply connector 4 is connected to the external artificial airway, so that the oxygen in the external oxygen supply system can enter the patient's artificial airway through the first oxygen supply channel inside the oxygen source connector The inner diameter of the second top surface 41 is smaller than the inner diameter of the second bottom surface 42 of the oxygen supply connector 4, so that the diameter of the oxygen supply connector 4 can be gradually increased from the external artificial airway to the connecting head 3.

It should be noted that although a certain amount of oxygen will leak out from the leak hole 5 during the process of supplying oxygen to the patient, a certain amount of oxygen consumption may occur during the oxygen supply, and the amount of oxygen leaking out through the leak hole 5 is within the allowable range and will not have a significant impact on the patient's oxygen supply.

In some possible implementations, the number of the leakage holes 5 is two, and the two leakage holes 5 are symmetrically opened at one end of the side wall of the connector 3 close to the oxygen supply connector 4 .

This is because an annular convex groove is provided on the outer side of the clamping end 11 of the oxygen source connector 1, and the clamping end 11 can be clamped with the external oxygen supply system through the annular convex groove, and the oxygen source connector and the annular convex groove made of soft polyvinyl chloride material have a certain flexibility, which can make the annular convex groove on the outer side wall of the oxygen source connector and the inner side of the external oxygen supply system clamped more tightly.
