Abstract
Description
Technical Field
[0001] This invention relates to the field of medical device technology, and in particular to an oral cavity treatment device for postoperative oral surgery. Background Technology
[0002] Oral surgery is a specialized procedure in oral medicine that treats oral and maxillofacial diseases, injuries, or deformities using surgical methods. It encompasses a wide range of procedures and varies considerably in technical difficulty. After oral surgery, patients require regular disinfection and medication of the wound, necessitating the use of specialized oral care devices.
[0003] Existing oral treatment devices generally use a spraying component to directly spray medication into the patient's mouth to achieve the purpose of medication and disinfection. However, the medication is prone to sedimentation after being left for a long time. In addition, existing devices lack an integrated structure that can stir the medication during use, resulting in uneven mixing of the medication, which affects the therapeutic effect. Therefore, we provide an oral treatment device for postoperative use in oral surgery. Summary of the Invention
[0004] To address the problem of difficulty in uniformly stirring precipitated medications in the aforementioned background technology, the present invention provides an oral treatment device for postoperative use in oral surgery.
[0005] The present invention is achieved by the following technical solution: an oral treatment device for postoperative oral surgery, including a drug storage tank for storing medicine, a spraying component fixedly connected to the top of the drug storage tank, a stirring component inside the drug storage tank, and a shaking component on the drug storage tank.
[0006] As a further improvement to the above solution, the spraying assembly includes a dispensing cylinder fixedly connected to the center of the top of the storage tank. A sealing piston for extracting the pesticide is movably connected inside the dispensing cylinder. A lead screw is vertically fixedly connected to the center of the top of the sealing piston, with the top end of the lead screw extending to the outside of the dispensing cylinder. A bracket is fixedly connected to the top of the dispensing cylinder. A helical tube is rotatably connected to the bracket, and the helical tube is threadedly connected to the lead screw. A motor is also fixedly connected to the bracket. A rotating shaft is coaxially fixedly connected to the end of the motor rotor. Gears are fixedly fitted onto the outside of both the rotating shaft and the helical tube, and the gears mesh with each other. An inlet pipe is fixedly connected between the inlet of the dispensing cylinder and the storage tank. A flexible tube is fixedly connected to the outlet of the dispensing cylinder. A connecting pipe is fixedly connected to the end of the flexible tube, and a spray head is fixedly connected to the end of the connecting pipe.
[0007] As a further improvement to the above solution, the stirring assembly includes a hollow rotating shaft rotatably connected inside the medicine storage tank. Stirring rods for stirring the medicine are fixedly connected equidistantly around the outside of the hollow rotating shaft. A fixing rod is vertically fixedly connected to the bottom center of the sealing piston, and the bottom end of the fixing rod extends movably into the interior of the hollow rotating shaft. A T-shaped frame is fixedly connected to the bottom end of the fixing rod. Two sets of ball bearings are symmetrically and movably arranged on the T-shaped frame. The inner wall of the hollow rotating shaft has a groove with a spiral structure that matches the position of the ball bearings.
[0008] As a further improvement to the above solution, the shaking assembly includes an eccentric wheel fixedly sleeved on the outer side of the upper part of the hollow rotating shaft. A connecting plate is provided on one side of the eccentric wheel. Two sets of crossbars are symmetrically fixedly connected to the connecting plate, and the ends of the crossbars extend movably to the outside of the medicine storage tank. The ends of the two sets of crossbars are fixedly connected to the same strip plate. A spring is sleeved on the outside of the crossbar. A connecting rod is fixedly connected to the center of one side of the strip plate. A ring is fixedly sleeved on the outside of the connecting tube. A fixing frame is fixedly connected to the outside of the medicine storage tank, and the fixing frame and the ring are hinged together by a hinge. A movable block is movably connected to the outside of the ring, and the movable block is hinged to the connecting rod by a hinge.
[0009] As a further improvement to the above solution, a liquid injection pipe for adding liquid medicine into the storage tank is fixedly connected to one side of the top of the storage tank, and a sealing cap for preventing the liquid medicine from spilling is threaded onto the outside of the injection pipe.
[0010] As a further improvement to the above solution, two sets of guide rods are symmetrically fixedly connected to the top of the sealing piston, and the guide rods are slidably connected to the dispensing cylinder, so as to provide a certain guiding effect for the vertical movement of the sealing piston.
[0011] As a further improvement to the above solution, a one-way valve is installed inside both the inlet pipe and the connecting pipe. The opening direction of the one-way valve inside the inlet pipe is consistent with the direction of liquid inflow, and the opening direction of the one-way valve inside the connecting pipe is consistent with the direction of liquid outflow.
[0012] As a further improvement to the above solution, the inside of the medicine storage tank is horizontally fixedly connected with a partition, and a sealing ring is added at the rotatable connection between the partition and the hollow rotating shaft. A sealing ring is added at the sliding connection between the fixed rod and the medicine dispensing cylinder, which can play a sealing role and prevent the medicine from leaking.
[0013] As a further improvement to the above solution, the two ends of the spring are fixedly connected to the inner wall of the medicine storage tank and the connecting plate, respectively.
[0014] As a further improvement to the above solution, the movable block is designed with a T-shaped structure, and a T-shaped moving groove is provided on one side of the ring, and the moving groove is slidably connected to the movable block.
[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. When the motor is started, the meshing action between gears drives the spiral tube to rotate. The sliding engagement between the guide rod and the dispensing cylinder, and the threaded connection between the spiral tube and the lead screw, drive the sealing piston to rise vertically, thereby drawing the medicine from the storage tank into the dispensing cylinder. By controlling the motor to reverse, the sealing piston is driven to fall vertically, pushing the drawn medicine into the spray head and spraying it out. This achieves the purpose of automatically applying medicine and disinfecting oral wounds, and is highly practical.
[0016] 2. In the process of driving the sealing piston to move vertically, the present invention can also drive the fixed rod to move together. The movement of the fixed rod will drive the ball bearings on the T-shaped frame to move simultaneously. With the cooperation between the ball bearings and the groove, and the rotational cooperation between the hollow rotating shaft and the medicine storage tank, the hollow rotating shaft can be driven to rotate, thereby driving the stirring rod to rotate to stir the medicine to ensure the uniformity of the medicine solution, and thus ensure the therapeutic effect of the medicine on the oral wound.
[0017] 3. During the rotation of the hollow shaft, the invention can also drive the eccentric wheel to rotate together. When the eccentric wheel contacts the connecting plate, as the eccentric wheel continues to rotate, it will squeeze the connecting plate. Utilizing the sliding fit between the crossbar and the medicine storage tank, the connecting plate will move to one side and compress the spring. Utilizing the hinged fit between the ring and the fixed frame, the sliding fit between the movable block and the moving groove, and the hinged fit between the movable block and the connecting rod, the connecting plate can push the spray head to deflect slightly to one side when it moves. When the eccentric wheel rotates away from the connecting plate, the spring's own rebound action will cause the spray head to automatically return to its original position, thereby increasing the disinfection range inside the oral cavity and ensuring the treatment effect on oral wounds.
[0018] 4. During the back-and-forth swinging of the spray head, the present invention can also shake off the oral mucus adhering to the spray head, thereby preventing oral mucus from clogging the spray head and ensuring stable application of medicine to the oral wound. Attached Figure Description

[0025] The swaying assembly includes an eccentric wheel 301 fixedly sleeved on the outer side of the upper part of the hollow rotating shaft 201.

[0026] The implementation principle of the oral treatment device for post-oral surgery in this embodiment is as follows: First, hold the device and place the spray head 110 in the patient's mouth. Then, start the motor 105. When starting the motor 105, the meshing action between the gears 106 drives the screw tube 104 to rotate. The sliding engagement between the guide rod 111 and the dispensing cartridge 101, and the threaded connection between the screw tube 104 and the lead screw 103, causes the sealing piston 102 to rise vertically, thereby drawing the medication from the storage tank 1 into the dispensing cartridge 101. By controlling the motor 105 to reverse, the sealing piston 102 can be driven to rise vertically. The piston 102 descends vertically, pushing the extracted medication into the spray head 110 and spraying it out, thus achieving automatic disinfection of the oral wound. Simultaneously, the vertical movement of the sealing piston 102 also moves the fixing rod 203. The movement of the fixing rod 203, in turn, moves the ball bearings 205 on the T-shaped frame 204. The interaction between the ball bearings 205 and the groove 206, along with the rotational engagement between the hollow rotating shaft 201 and the medication storage tank 1, drives the hollow rotating shaft 201 to rotate. This, in turn, drives the stirring rod 202 to agitate the medication, ensuring uniform mixing of the solution. This ensures the therapeutic effect of the medication on the oral wound. Simultaneously, the rotation of the hollow shaft 201 also drives the eccentric wheel 301 to rotate. When the eccentric wheel 301 contacts the connecting plate 302, its continued rotation causes it to compress the connecting plate 302. Utilizing the sliding engagement between the crossbar 303 and the medicine storage tank 1, the connecting plate 302 moves to one side and compresses the spring 305. The hinged engagement between the ring 307 and the fixed frame 308, the sliding engagement between the movable block 309 and the moving groove 310, and the hinged engagement between the movable block 309 and the connecting rod 306 further enhance the effect. The connecting plate 302 can push the spray head 110 to one side slightly when it moves. After the eccentric wheel 301 rotates away from the connecting plate 302, the spray head 110 will automatically return to its original position due to the rebound effect of the spring 305. This increases the disinfection range inside the oral cavity and further ensures the treatment effect on the oral wound. In addition, the back-and-forth swinging of the spray head 110 can shake off the oral mucus adhering to the spray head 110, thereby preventing oral mucus from clogging the spray head 110 and ensuring stable medication application to the oral wound. Finally, the spray head 110 can be removed from the patient's mouth after the medication application is completed. Example 2:
[0027] Based on Example 1, this embodiment is further improved in that: a liquid injection pipe 2 for adding medicine to the inside of the medicine storage tank 1 is fixedly connected to one side of the top of the medicine storage tank 1, the end of the liquid injection pipe 2 passes through the partition 3, and a sealing cap for preventing the medicine from spilling is threaded to the outside of the liquid injection pipe 2.
