DETAILED DESCRIPTION

[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the protection scope of the utility model.

[0019] An embodiment of the utility model, as Figure 1As shown, one end of the straw body 1 is connected to a steerable bellows elbow 3, and medical staff can manually bend the bellows elbow 3 to a suitable angle according to actual usage, which is convenient for cleaning some blind spots and avoids blocking the medical staff's line of sight. The other end is connected to the cleaning liquid container through an external pipeline, and the other end of the bellows elbow 3 is connected to a plug connector 4, and a detachable suction head 2 is clamped in the plug connector 4. The detachable suction head 2 includes a connecting tube body 21 clamped with the plug connector 4, and a connecting plate 22 is fixed to the other end of the connecting tube body 21. A toothbrush head 23 and a sponge brush head 24 are respectively arranged on both sides of the connecting plate 22. The detachable suction tube structure can complete the treatment of different patients by replacing the suction head, thereby reducing production costs and reducing waste of raw materials.

[0020] A liquid outlet 221 is provided in the center of the connecting plate 22 and penetrates along the thickness direction of the connecting plate 22. The liquid outlet 221 is connected to the pipeline inside the connecting tube body 21 to ensure that the cleaning liquid can flow out of the liquid outlet 221 smoothly, or suck out the cleaning liquid in the patient's mouth.

[0021] The liquid outlet hole 221 on one side of the connecting plate 22 close to the toothbrush head 23 is expanded into a waist-shaped groove, and bristles are distributed on the outer circle of the waist-shaped groove to increase the liquid output of the cleaning liquid. If necessary, an atomizing nozzle can be installed to spray the cleaning liquid in a mist form on the patient's teeth cleaning area, thereby improving the applicability of the product.

[0022] A rib 211 is provided at the connection position between the connecting tube body 21 and the plug connector 4, a joint 212 is provided on the side of the rib 211 close to the plug connector 4, and a sealing ring 213 bonded to the rib 211 is provided at the root of the joint 212 to improve the connection strength and sealing between the detachable suction head 2 and the plug connector 4 to avoid leakage of cleaning liquid or falling off of the suction head during use.

[0023] The surface of the sponge brush head 24 is provided with a serrated structure, and a liquid suction channel connected to the liquid outlet 221 is opened in the center of the sponge brush head 24. When the cleaning liquid and debris in the patient's mouth need to be cleaned out, the medical staff will aim the sponge brush head 24 at the patient's teeth, and the impurities will be adsorbed on the surface of the sponge brush head 24. At the same time, the liquid outlet 221 is prevented from directly contacting the patient's oral mucosa during the suction process to cause damage.

[0024] A thumb valve 11 and a gripping portion 12 are respectively provided on the left and right sides of the straw body 1 which are symmetrical about the central axis. The gripping portion 12 includes four groups of grooves that fit the fingers, which is more suitable for the ergonomic structure of human hand grip, closes the microphone and prevents slipping, thereby improving the gripping strength of medical staff.

[0025] The surface of the thumb valve 11 is provided with an arc-shaped thumb pressing surface 111, and the center of the thumb pressing surface 111 is provided with an inclined negative pressure chamber 112, which is connected to the pipeline inside the straw body 1. During the suction process, the externally connected cleaning liquid container starts the negative pressure suction function, and the medical staff presses the negative pressure chamber 112 position of the thumb valve 11 with their thumb to form a negative pressure inside the suction tube, which is convenient for suctioning the cleaning liquid and impurities remaining in the patient's mouth.

[0026] The working principle of this embodiment is as follows: before use, the medical staff disinfects the straw body and installs it on the pipe connected to the cleaning liquid container, takes out the detachable suction head from the package, disinfects it and installs it to the plug position of the straw body, manually adjusts the bellows elbow to a suitable angle and then aims the toothbrush head at the patient's teeth, starts the cleaning function of the cleaning liquid container, and the cleaning liquid flows along the straw body to the toothbrush head. During the process of brushing the patient's tooth surface, the cleaning liquid continuously flows out to improve the cleaning effect; after the cleaning is completed, the sponge brush head is aimed at the patient's teeth, and the suction function of the cleaning liquid container is started. The medical staff presses the thumb valve with his thumb to suck out the cleaning liquid and impurities in the patient's mouth. If the liquid drawing channel on the sponge brush head sucks the oral mucosal tissue, the thumb can release the negative pressure when it leaves the thumb valve to avoid mucosal damage.
