Description

Technical Field

[0001] The present invention relates to a safe synchronous sputum drainage and oxygen supply tracheal intubation tube. Background Art

[0002] Tracheal intubation: It is the most effective and reliable method for establishing an artificial airway, referring to the technique of inserting a special tracheal catheter through the oral cavity or nasal cavity and into the trachea through the glottis. This technique can provide the best conditions for relieving airway obstruction, ensuring airway patency, clearing airway secretions, preventing aspiration, and performing assisted or controlled ventilation, etc. It is commonly used in endotracheal anesthesia and the rescue of critically ill patients.

[0003] For example, the utility model patent with the publication number CN215537528U discloses a multifunctional tracheal intubation tube. And the utility model patent with the publication number CN215875853U discloses a tracheal intubation tube with a self-locking and movable bite block.

A driving mechanism for driving the left water wheel and the right water wheel to rotate in opposite directions is arranged inside the tracheal intubation body, so as to drive the left water wheel to rotate counterclockwise and the right water wheel to rotate clockwise. The sputum is scraped by the cooperation of the left water wheel and the right water wheel and gradually discharged towards the head end direction. See Figure 4 and Figure 5 .

[0023] In this embodiment, in order to better discharge the sputum towards the head end direction, the left water wheel and the right water wheel are arranged with an offset in the vertical direction. The left water wheel and the right water wheel have the same diameter. The distance between two adjacent upper and lower left water wheels is equal to the distance between two adjacent upper and lower right water wheels, and the distance between two adjacent upper and lower left water wheels is less than the diameter of the left water wheel. The right water wheel scrapes the sputum upwards clockwise, the left water wheel located above the left of the right water wheel rotates counterclockwise to scrape the sputum upwards, and then the right water wheel located above the right scrapes the sputum upwards. The left water wheel and the right water wheel act alternately to discharge the sputum towards the head end direction of the tracheal intubation.

[0024] In this embodiment, both the left water wheel and the right water wheel include a rim 24. On the circumferential surface of the rim, a plurality of baffle plates 25 are radially fixed at intervals along the circumferential direction.

A driving gear 30 is fixed on each driving shaft, and the driving gear is meshed with a left driven gear 32 on the left water wheel shaft disposed on the upper left through an intermediate wheel 31, and the driving gear is meshed with a right driven wheel 33 on the right water wheel shaft disposed on the lower right. Thereby, the two adjacent left water wheels and right water wheels rotate in opposite directions. Specifically, the driving shaft rotates counterclockwise, the left wheel rotates counterclockwise, and the right water wheel rotates clockwise. See. Figure 5 .

[0026] In this embodiment, a motor for driving the uppermost drive shaft is provided at the head end of the endotracheal tube. The motor is a micro motor 34. The output shaft of the micro motor is connected to the uppermost drive shaft. The motor is connected to an external power supply (e.g., a battery with an output voltage of 5V) so as to realize automatic sputum scraping and expectoration. Figure 6 .

[0027] Or a crank 35 for driving the uppermost drive shaft is provided at the head end of the endotracheal tube, and the crank is connected to the uppermost drive shaft, so that the left and right water wheels can be driven to rotate by manually rotating the crank. Figure 7 .
