As shown in fig. 1, an embodiment of the present invention provides a medical ear canal cleaning device, which includes a tube 2, a suction unit 1, a movable member 3, and a holding portion 5. The suction device 1 is mounted at one end 21 of the tubular body 2 and communicates with the inside of the tubular body 2 to adsorb the cotton wad 4 through the other end 22 of the tubular body 2. Wherein, the air breathing device 1 may include an elastic air bag to be connected with the tube body 2 through the elastic air bag. The elastic air bag is provided with an air inlet and an air outlet, and the elastic air bag is fixedly connected with the port of one end 21 of the tube body through the air inlet and the air outlet. The elastic air bag can exhaust air through the other end 22 of the tube body 2 when being pressed; when the elastic air bag is released, the elastic air bag sucks air through the other end 22 of the tube body 2 to form a negative pressure at the other end 22 of the tube body 2, so that the cotton ball 4 can be adsorbed.

The movable member 3 is sleeved on the tube body 2 and can reciprocate along the length direction of the tube body 2. The moving part 3 can be the tube-shape, and the moving part 3 cover is established on the lateral wall of body 2, and with the lateral wall sliding fit of body 2. In order to improve the motion precision of the moving part 3, preferably, the outer side wall of the tube body 2 is provided with a limiting convex column extending along the length direction, and the limiting convex column can be integrally formed on the outer side wall of the tube body 2. The inner side of the moving part 3 is provided with a limiting groove penetrating through the two ends, and the limiting convex column is in sliding fit with the limiting groove so as to limit and guide the movement of the moving part 3. In order to move the movable member 3 conveniently, the outer side wall of the movable member 3 may be provided with anti-slip lines.

As shown in fig. 2, the clamping portion 5 includes a clamping arm 54, a rotating shaft 51, an elastic member 52 and a wire 53. The clamping arm 54 is fixed on the rotating shaft 51, and the clamping arm 54 and the rotating shaft 51 can be of an integrated structure. The clamping arms 54 are mounted on the tube body 2 through the rotating shaft 51, a bracket is arranged on the outer side wall of the tube body 2, and the rotating shaft 51 is rotatably mounted on the bracket. The pivot 51 can drive the clip arms 54 to rotate together. One end of the cord 53 is connected to the rotating shaft 51, for example, is bound to the rotating shaft 51; the other end of the cord 53 is connected to the moveable member 3, for example, by being tied to the moveable member 3.

The number of the clamping portions 5 may be two or more. The movable piece 3 is used for driving each rotating shaft 51 to rotate through the thread rope 53 of each clamping part 5 when moving to the one end 21 along the pipe body 2, so that each clamping arm 54 is relatively opened or closed; each elastic element 52 is used to apply a force to the corresponding rotating shaft 51 to restore the movable element 3 and each clamping arm 54 to the initial position. The elastic member 52 may be a torsion spring, and the torsion spring is sleeved on the rotating shaft 51.

In a specific application example, as shown in fig. 2, the movable element 3 is used for driving the clamping arms 54 to close relatively when moving along the tube body 2 to the end 21 to the extreme position; as shown in fig. 5, each elastic member 52 is used for applying a force to the corresponding rotating shaft 51 to open each clamping arm 54 relatively. It is defined below that the one end 21 of the tubular body 2 is "lower" and the other end 22 of the tubular body 2 is "upper". In this example, when the movable element 3 moves downward, the movable element 3 pulls the rotating shaft 51 through the cord 53, so that the clamping arms 54 are relatively closed. When the movable element 3 is released, the shafts 51 drive the arms 54 to open relatively under the action of the elastic element 52, and drive the movable element 3 to return to the initial position. Of course, in another example, when the movable member 3 moves downward, the movable member 3 can pull the rotating shaft 51 through the cord 53, so that the clamping arms 54 are relatively opened. When the movable element 3 is released, the shafts 51 drive the arms 54 to close relatively under the action of the elastic element 52, and drive the movable element 3 to return to the initial position.

As shown in fig. 3 and 4, the sidewall of the tube 2 may be provided with air holes 202, and the number of the air holes 202 may be two or more.

As shown in fig. 4, when the clamping arms 54 are closed relatively, each clamping arm 54 clamps the cotton ball 4, the moving member 3 moves away from the air hole 202 and opens the air hole 202, and at this time, the medical staff can not only clean earwax in the ear canal of the patient through the cotton ball 4, but also suck or blow away the earwax through the air hole 202, so that the cleaning efficiency is high.

As shown in fig. 4, the air hole 202 may be provided with an air tube 9, so as to enter and exit air through the air tube 9. The air inlet and outlet direction of the air pipe 9 is adjustable, so that medical staff can conveniently suck or blow away earwax in the auditory canal of the patient from a proper direction according to actual conditions.

In order to adjust the air inlet and outlet direction of the air tube 9, as shown in fig. 4, the medical ear canal cleaning device may further include an inner tube 7, wherein the inner tube 7 is sleeved inside the tube body 2 and can move along the length direction of the tube body 2. The inner cylinder 7 is used for driving the air pipe 9 to swing along the length direction of the pipe body 2 so as to adjust the air inlet and outlet direction of the air pipe 9. Wherein, the one end 21 of the tube 2 is defined as "lower" and the other end 22 is defined as "upper". In this example, the inner cylinder 7 can drive the air pipe 9 to swing up and down. The inner cylinder 7 is in sealing and sliding fit with the inner wall of the tube body 2, and preferably, the inner cylinder 7 and the inner wall of the tube body 2 are sealed in a surface-to-surface contact direction. The side wall of the inner cylinder 7 is embedded with a rotatable spherical part 8, the air pipe 9 penetrates through the spherical part 8, is communicated with the interior of the tube body 2 through the inner cylinder 7, and one end of the air pipe extends into the air hole 202. One side edge of the inner opening of the air hole 202 is used for abutting against the outer side wall of the air pipe 9 when the inner cylinder 7 moves to the limit position along the length direction of the tube body 2 so as to push the air pipe 9, so that the air pipe 9 swings through the spherical part 8. Specifically, the upper edge of the inner opening of the air hole 202 can push the air pipe 9 to swing downwards when the inner cylinder 7 moves to the upper limit position along the tube body 2, and the lower edge of the inner opening of the air hole 202 can push the air pipe 9 to swing upwards when the inner cylinder 7 moves to the lower limit position along the tube body 2.

As shown in fig. 6, the inner cylinder 7 may be provided with a handle portion 71, and the handle portion 71 may be fixed to an outer sidewall of the inner cylinder 7. Another limiting groove 201 is arranged on the side wall of the tube body 2, and the handle portion 71 is used for driving the inner tube 7 to move along the other limiting groove 201 so as to limit and guide the movement of the inner tube 7.

Here, it should be noted that: in the above example, when cleaning the ear canal of a patient using the medical care device of the present invention, the health care professional only needs to prepare the cotton ball 4. Compared with the prior art, the stick is not needed, so that the resources of the stick are saved, and the waste of the resources is reduced.

For convenience of operation, it is avoided that the user always needs to tighten the mobile element 3 when moving it to the distal end, where "distal end" refers to the position in which the mobile element 3 moves to the extreme position along the tubular body 2 towards said one end 21 thereof. Preferably, the medical ear canal cleaning device of the present invention may further comprise a fixing means 6, wherein the fixing means 6 is used for fixing the movable member 3 when it moves to the extreme position along the tubular body 2 towards the one end 21 thereof. As shown in fig. 2, the fixing mechanism 6 may include a locking portion 61 and a locking groove portion 62, one of the locking portion 61 and the locking groove portion 62 is disposed on the tube body 2, and the other is disposed on the movable member 3. The locking portion 61 is used for being locked in the locking groove portion 62 when the movable member 3 moves to the limit position along the tube body 2 toward the one end 21 thereof, so as to fix the movable member 3. In a specific application example, the aforementioned locking portion 61 is disposed on the tube body 2, and one end of the locking portion 61 is fixed on the tube body 2, for example, integrally injection-molded on the outer side wall of the tube body 2. The aforementioned notch portion 62 is provided on the movable member 3. The end 21 of the movable element 3 close to the tube 2 is provided with a tapered guide surface 31, and the tapered guide surface 31 is used for guiding the snap-fit portion 61 to slide towards the snap-fit portion 62.

Preferably, the number of the fixing mechanisms 6 can be more than two, so as to improve the fixing effect of the movable member 3 at the far end.

As shown in fig. 5 and 6, when the clamping arms 54 are opened relatively, each clamping arm 54 does not protrude from the end surface of the other end 22 of the tube 2, so as to mainly avoid the interference of each clamping arm 54 on the other end 22 of the tube 2 when adsorbing the cotton ball 4.
