Further, the lower end of the tracheal cannula body is a flexible part.
The beneficial effect of adopting the further technical scheme is that: the lower end of the tracheal cannula body is a flexible part, so that stimulation of the tracheal catheter to the throat and glottis of a patient can be reduced, and pain of the patient is relieved.
Further, the sampling port is a circular tube and is in threaded connection with the conduit communication valve.
The beneficial effect of adopting the further technical scheme is that: when sampling is needed, the sampling port is unscrewed for sampling; when sampling is not needed, the sampling device is in a closed state and works normally.
Further, the diameter of the first pore passage is matched with a threaded pipe of a breathing machine or an anesthesia machine.
The beneficial effect of adopting the further technical scheme is that: the diameter of the first pore passage is matched with a threaded pipe of a breathing machine or an anesthesia machine, and ventilation or drug administration is carried out on a patient.
Further, the diameter of the second pore passage is matched with that of a threaded pipe of the cleaning machine.
The beneficial effect of adopting the further technical scheme is that: the diameter of the second pore passage is matched with the threaded pipe of the cleaning machine, so that when the respiratory tract secretion is more, the suction can be synchronously performed in the process of ventilating the patient, and the secretion can be timely removed.
Further, the tooth back cuff is a silica gel cuff.
The beneficial effect of adopting the further technical scheme is that: the silica gel cuff is soft in texture and good in sealing performance, and can reduce damage to the trachea and the like of a patient and ensure the airtightness of the trachea.
