The formation of sputum scab not only affects the normal respiratory function of patients, but also can cause airway obstruction, further aggravate the condition, and even cause respiratory failure. Therefore, removing sputum scab is one of the key measures to ensure the smoothness of respiratory tract and improve the quality of respiration.

[0003] Since the cost of electric control scab removing equipment is high, and the airway of part of patients is relatively fragile, the mechanical operation of electric control equipment can easily damage the respiratory tract wall of patients. Therefore, the existing sputum scab removing method mainly relies on manual operation, and the cleaning of sputum scab is realized by airway flushing and manual sputum suction. However, the sputum scab has high viscosity, and it is difficult to suck out and clean by traditional flushing and adsorption, which leads to incomplete cleaning effect and low efficiency in actual operation. Therefore, medical staff need to physically scrape according to the condition of patients by rotating guide head and force control. The rotating operation needs to be adjusted by finger rotation, which is not convenient to apply force, and long-time operation can also aggravate the fatigue of finger muscles of medical staff.

[0026] The occlusion component 5 includes upper tooth bite sleeve 501 and lower tooth bite sleeve 502, and the upper tooth bite sleeve 501 and the lower tooth bite sleeve 502 are connected through an elastic connecting belt 503. Specifically, the guide pipe 1 passes through between the upper tooth bite sleeve 501 and the lower tooth bite sleeve 502, the mouth of the patient is opened by the occlusion component 5, and the situation that the guide pipe 1 is bitten when the guide pipe 1 is inserted into the throat and enters the trachea of the patient can be avoided. In addition, during the operation of medical staff, the insertion length of the guide pipe 1 needs to be adjusted, at this time, the patient can still adjust the insertion distance by pulling the guide pipe 1 when biting the occlusion component 5, and then the screw rod 2 is operated.

[0027] The bearing 6 includes an inner ring and an outer ring that cooperate with each other, the inner ring of the inner ring is fixed to the outer wall of the inthrust end of the guide pipe 1, and the opening end of the filter screen cover 3 is fixedly connected with the outer ring. Specifically, the filter screen cover 3 rotates relative to the guide pipe 1, in the present application, the guide pipe 1 is pushed into the throat of the patient and inserted into the sputum scab, at this time, the filter screen cover 3 cooperating with the screw rod 2 can be rotated by longitudinally moving the screw rod 2. At this time, the filter screen cover 3 can rotate freely under the condition that the guide pipe 1 is stationary, and the sputum scab attached to the wall of the airway of the patient is scraped and cleaned by the rotation of the filter screen cover 3.

[0028] The two accommodating cavities 4 are symmetrically arranged on the inner walls of the guide pipe 1. Specifically, during the sputum scab cleaning process, the functions of flushing and sucking sputum scab are realized by connecting the suction pipe and the flushing pipe. The suction pipe is connected with a negative pressure pump, and the flushing pipe is connected with a flushing nozzle. Preferably, according to the condition of the patient, an oxygen supply catheter or a medicine guide tube can be inserted into any accommodating cavity 4.

When the guide tube 1 contacts the sputum crust, the flushing nozzle and negative pressure pump are turned on. During this process, the healthcare worker pushes and pulls the operating handle 9 back and forth, causing the spiral rod 2 to rotate the filter screen 3. The back-and-forth movement of the filter screen 3 also causes it to rotate reciprocally, similar to a bamboo dragonfly toy. The circular protrusions 10 on the outer wall of the filter screen 3 contact the sputum crust, creating a scraping effect. With the help of the suction and flushing tubes, the sputum crust adhering to the inner wall of the airway is cleaned and removed. After the sputum crust removal is complete, the negative pressure pump and flushing fluid source are turned off, and the guide tube 1 and jawbone assembly 5 are removed, completing the operation.
