[0002] The oral disinfection device before dental implantation is a device used to disinfect the oral cavity before dental implant surgery, aiming to reduce the risk of infection during the surgery.

[0003] Existing oral disinfection devices usually use a handheld sprayer to disinfect the oral cavity. This method is difficult to thoroughly disinfect the deeper parts of the oral cavity, resulting in inadequate disinfection of many places inside the oral cavity. This makes it easy for bacteria to be infected during the subsequent dental implantation process, causing secondary damage to the patient. Therefore, we propose an oral disinfection device before dental implantation. Utility Model Content

[0078] A specific application of this embodiment is:

[0079] When in use, the right side of the connecting nozzle 31 is fixed to the left side of the delivery tube 112 by means of threads, and then the infusion tube 42 is fixed to the right side of the delivery tube 112 by means of threads through the joint 41. The other end of the infusion tube 42 is used to connect to an external disinfectant delivery device. When the oral cavity needs to be disinfected, the disinfectant is delivered to the delivery tube 112 through the infusion tube 42. At this time, the medical staff holds the grip 111 to insert the connecting nozzle 31 into the patient's mouth, and aligns the end of the connecting nozzle 31 with the position that needs to be disinfected. Then the medical staff turns the threaded knob 214 counterclockwise to move it away from the housing 211, releases the fixation of the rack 212, and then pushes the threaded knob 214 to drive the rack 212 to move to the left, and the bottom of the rack 212 is in the T-slot 221. The rack 212 drives the slider 222 to slide in the slide groove 213 to improve the stability during movement. The rack 212 drives the gear 215 to rotate counterclockwise during movement. The gear 215 drives the turntable 125 to rotate together with the rotating rod 124. The turntable 125 pulls the connecting rod 141 through the fixed shaft 143 at the bottom. The connecting rod 141 drives the conical plug 123 to move to the left through the fixed shaft 143 and the fixed block 142 on the right side. At this time, the conical plug 123 opens the right side of the outer annular tube 121. The disinfectant enters between the outer annular tube 121 and the inner tube 122 and is transported to the delivery tube 112 on the left. At the same time, the disinfectant enters the connecting nozzle 31 and is sprayed out from the end, thereby disinfecting the patient's oral cavity.

[0080] The medical staff pushes the threaded knob 214 to different positions to control the moving distance of the tapered plug 123, thereby adjusting the opening size on the right side of the outer annular tube 121 to control the amount of disinfectant used. After the adjustment is completed, the threaded knob 214 is turned clockwise to make the threaded knob 214 contact with the housing 211 to fix the rack 212. At this time, the position of the tapered plug 123 remains unchanged. Since the end of the connecting nozzle 31 is small, any position in the oral cavity can be disinfected.

[0081] At the same time, during the disinfection process, the medical staff presses the control button 113 to start the air pump 131, and the air pump 131 generates gas and delivers it to the trachea 132. The gas is then ejected from the air outlet 133 and mixed with the disinfectant in the delivery pipe 112, so that the disinfectant can be ejected from the connecting nozzle 31 with a stronger pressure by blowing, and the mixture of gas and liquid can produce fine bubbles, so that the disinfectant will contain a large number of bubbles after being sprayed out, which has a comfortable effect on the patient's oral cavity. At the same time, this method can also play a certain cleaning role in the patient's oral cavity, which is more conducive to subsequent implantation work.
