The technical scheme is as follows:
in order to solve the technical problems, the invention adopts the following technical scheme: a self-rotating sputum aspirator comprises an inner tube, an outer tube and a connecting seat, wherein a rope winding disc, a coil spring, a driving shaft and a driving gear are arranged in the connecting seat, the rope winding disc and the driving gear are coaxially arranged on the driving shaft, two ends of the coil spring are respectively and fixedly connected with the driving shaft and the inner wall of the connecting seat, a pull rope is arranged on the rope winding disc, one end of the outer tube is connected with a driven gear, the other end of the outer tube is provided with bristles and extends out of the connecting seat, the end of the outer tube, which is provided with the brush hair, is also provided with an opening, the driven gear is matched with the driving gear, a pipe hole is formed in the center of the driven gear, the inner pipe is coaxially arranged in the outer pipe and penetrates through the pipe hole, one end of the inner tube is provided with a connector and extends out of the connecting seat, and the driving shaft and the outer tube are supported by bearings arranged in the connecting seat.
The inner tube passes through the connector is connected with the sputum aspirator, the outer tube is equipped with the one end of brush hair stretches into in the trachea cannula and inhales the phlegm, through the stay cord pulling the wire winding dish rotates, makes the coil spring tighten up, relaxes the stay cord, the driving gear is in the rebound force effect of coil spring rotates down, drives driven gear with the outer tube rotates, the brush hair of outer tube tip is clear away the eschar in the trachea cannula through the rotation, and material such as sputum and the eschar after clearing away passes through the opening is inhaled the inner tube, then passes through the inner tube gets into the sputum aspirator.
Furthermore, the outer tube divide into fixed outer tube and can dismantle the outer tube two sections, the one end of fixed outer tube with driven gear connects, the other end of fixed outer tube with can dismantle outer tube threaded connection, can follow to dismantle the outer tube can be dismantled on the fixed outer tube, the change of being convenient for guarantees the health.
Furthermore, a through-flow hole is formed in the position, corresponding to the opening, of the inner pipe, so that the through-flow between the inner pipe and the outer pipe is smooth, and blockage is prevented.
Furthermore, the connector is a corrugated pipe connector, so that the connector can be conveniently connected with a pipeline of the sputum aspirator.
(III) the beneficial effects are as follows:
compared with the prior art, the invention has the following beneficial effects: the self-rotation of the brush hair that is equipped with through the taut coil spring of stay cord on for outer tube and outer tube provides power, and the inner tube keeps motionless when the outer tube is rotatory, makes outer tube and brush hair can be when driving the phlegm scab from rotating, is convenient for drive the phlegm scab of adhering to on the trachea cannula inner wall, and the operation is effortless, convenient to use.
