Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.

Example 1

As shown in fig. 1-3 and 17-18, the tracheal cannula plug comprises an upper cover 1 and a lower cover 2, wherein the upper cover 1 is provided with an upper opening 3, the lower cover 2 is provided with a lower opening 4, the upper cover 1 is in threaded connection with the lower cover 2, a flow opening 5 is formed by the overlapping part of the upper opening 3 and the lower opening 4, the plug further comprises a telescopic pipe 6, the lower cover 2 is connected with one end opening part of the telescopic pipe 6, the other end of the telescopic pipe 6 is open, and the telescopic pipe 6 is further provided with a fixing structure 7.

In the initial use, the upper opening 3 and the lower opening 4 are completely overlapped, and the tracheal tube 27 is in a half-blocking state. When the upper cover 1 is rotated, the overlapping area between the upper opening 3 and the lower opening 4 is half of the half-blocking area, and the tracheal cannula 27 is in 3/4 blocking state. The upper cover 1 is rotated to stagger the upper opening 3 and the lower opening 4, and the tracheal cannula 27 is in a full-blocking state. The size of the flow opening 5 can be changed by rotating the upper cover 1, and gradual pipe blocking, namely half blocking, 3/4 blocking and full blocking, is realized.

When the patient coughs, a larger instant airflow impacts the tracheal cannula plug, and the tracheal cannula plug is very easy to separate from the tracheal cannula 27, so that the training of blocking the trachea fails. The tracheal cannula plug is provided with the telescopic pipe 6, the telescopic pipe 6 extends under the action of instant airflow generated by cough of a patient, the tracheal cannula plug can contain gas with a large volume, the gas generated by cough can be temporarily cached, the impact of the airflow generated by cough on the tracheal cannula plug is reduced, and therefore the condition that the plug falls off from the tracheal cannula 27 is reduced.

When the telescopic tube 6 is extended, medical staff and family members easily touch the tracheal tube plug accidentally, or medical appliances are accidentally touched by the medical staff during medical operation. And the scalable pipe 6 of this end cap can resume initial length, scalable pipe 6 shortens gradually after the air current slowly flows out through circulation mouth 5 promptly. The telescopic tube 6 is shorter after the initial length is recovered, so that medical staff and family members are prevented from accidentally touching the tracheal tube plug, and medical appliances are prevented from inadvertently touching the tracheal tube plug in the medical operation process.

More specifically, the telescopic tube 6 comprises a tube body 8, the wall of the tube body 8 is recessed outwards to form a plurality of hollow protrusions 9, the upper cover 1 is in threaded connection with the lower cover 2, and the upper part of the tube body 8 is connected with the lower cover 2. When the airflow generated by cough impacts the upper cover 1 and the lower cover 2, the tube body 8 is elongated, the cavity of the tube body 8 is enlarged in volume, the volume capable of containing the air is enlarged, the air generated by cough can be temporarily buffered, and the impact of the airflow generated by cough on the tracheal cannula plug is reduced.

Further, the upper opening 3 is a half-tai chi shape, and the lower opening 4 is a half-tai chi shape matched with the upper opening 3. The half-tai chi shape includes a circular arc edge 12, a convex arc edge 13, and a concave arc edge 14. The edge of circulation port 5 is the arc, and the air current that coughs the production flows when circulation port 5 blowout, and the air current flow path has taken place to change, has changed flow field structure, has reduced air current blowout circulation port 5's resistance, when the patient coughs promptly, adopts half taiji shape's upper shed 3 and under shed 4 can reduce air current blowout resistance, and the air current is spout from circulation port 5 more easily to the problem that the end cap breaks away from on tracheal cannula 27 when further having solved the patient and coughs.

The lower end surface of the upper cover 1 is a first flow guide surface 15 gradually steeped from the edge to the center, the upper end of the lower cover 2 is a groove 16 matched with the first flow guide surface 15, and the lower end surface of the lower cover 2 is a second flow guide surface 17 gradually steeped from the edge to the center. The first guide surface 15 and the second guide surface 17 guide the flow of the air flow, so that the air flow can flow out of the plug more easily.

More specifically, the fixed structure comprises an annular air bag 18, an air delivery pipe 19 and a clamping device 20, wherein the clamping device 20 is a clamp, and the annular air bag 18 is sleeved on the telescopic pipe 6. When the telescopic tube is used, the telescopic tube 6 is placed into the air pipe sleeve 27, the annular air bag 18 is located between the telescopic tube 6 and the air pipe sleeve 27, air is transmitted to the annular air bag 18 through the air transmission tube 19, the annular air bag 18 expands and enlarges, the air transmission tube 19 is clamped and closed by the clamp, and at the moment, the telescopic tube 6 and the air pipe sleeve 27 are relatively fixed. When the plug needs to be removed, the clamp is opened and the annular air bag 18 is discharged. The fixing between the plug and the tracheal tubes 27 of different specifications is realized by adjusting the expansion degree of the annular air bag 18, the fixing is firm, the operation is simple, and the use is convenient.

After the trachea is cut, the upper respiratory tract completely loses the heating, humidifying and filtering functions of gas, the defense function is weakened, sputum scabs are easily formed on the artificial airway or the upper respiratory tract, and once the sputum scabs are formed, the bronchus can be blocked, the airway resistance is increased, peripheral dyspnea and asphyxia are caused, and the solution is that medical staff humidify the airway. The telescopic tube 6 is connected with a hose 25, and a tube cap 26 is arranged on the hose 25. When in use, the tube cap 26 is opened, and the hose 25 is connected with the infusion extension tube for humidifying the air passage. After humidification is complete, the cap 26 is replaced over the hose 25.
