Description

Technical Field

[0001] This invention belongs to the technical field of oral spraying equipment, specifically referring to an oral visual sprayer. Background Technology

[0002] Oral sprayers are common instruments used to apply medication to lesions in the oral cavity, and are widely used in the treatment of oral ulcers, inflammation, and postoperative wounds. Currently, most civilian oral sprayers operated by patients themselves are simple direct-spray bottles or ordinary extension tubes.

[0003] However, existing equipment has significant shortcomings: First, patients cannot directly see the inside of their mouths and can only spray medication blindly by feel, making it difficult to accurately deliver the medication to the lesions and easily resulting in the spraying of healthy mucosa; second, the spray tube is a rigid straight tube that cannot be bent or adjusted, making it difficult to reach the deep corners of the mouth; third, it lacks a tooth support structure, causing patients to become fatigued from prolonged mouth opening, and sudden closure may bite soft tissue or damage the equipment; fourth, it lacks an effective antibacterial isolation design, and repeated use can easily lead to cross-infection. Therefore, this application solves the above problems by integrating a visual camera with supplemental lighting, a flexible snake-bone joint segment, a conical inlet support, and a replaceable antibacterial sleeve, achieving precise, safe, and hygienic oral medication spraying operation. Summary of the Invention

[0004] In response to the above issues, and to overcome the shortcomings of existing technologies such as patients not being able to directly see the inside of their mouths, the inability to bend and adjust the spray tube, the lack of tooth support structures, and the absence of antibacterial isolation design, this invention provides a visual oral sprayer. It effectively solves the problems of current oral sprayers on the market, such as blind spraying leading to inaccurate delivery of medication to lesions, inability to reach deep corners of the mouth, the risk of biting soft tissue or damaging the device due to prolonged mouth opening, and the risk of cross-infection from repeated use.

[0005] The technical solution adopted by the present invention is as follows: The present invention provides an oral visual sprayer, including a housing, a display, an antibacterial sleeve, a transmission component, and a visual spray hose. The display is hinged to the top wall of the housing. The transmission component is snapped into the housing. The visual spray hose is snapped into contact with the transmission component and slides within the housing. The antibacterial sleeve is fitted onto the outer wall of the visual spray hose, and both ends of the antibacterial sleeve are snapped into contact with the visual spray hose and the housing, respectively. The antibacterial sleeve has the good tensile properties of rubber.

[0006] Furthermore, the housing includes a handheld component, an end-limiting component, and a front-end inlet component. The handheld component is engaged with the transmission assembly. The end-limiting component is fixedly mounted on the handheld component, and the bottom wall of the handheld component is coplanar with the bottom wall of the end-limiting component. The width of the handheld component is smaller than the width of the end-limiting component, which prevents the entire device from slipping and falling into the mouth when the hand is holding the handheld component. The height of the handheld component is greater than the height of the end-limiting component. The display is hinged to the top wall of the end-limiting component, and the hinge point between the end-limiting component and the display is far from the handheld component. The sum of the heights of the end-limiting component and the display is the same as the height of the handheld component, effectively ensuring the integrity of the device after the display is closed, and preventing damage to the device under external impact. The front-end inlet component is designed as a conical structure with a flat top. The length of the front-end inlet component inserted into the mouth varies depending on the size of the mouth opening, and it can also support the teeth, preventing the teeth from closing during spraying and thus avoiding damage to the device.

[0007] Furthermore, the transmission assembly includes a forward drive gear, a ring rack, a deflection gear, and a toothed gear. The deflection gear and the toothed gear are both rotatably mounted on the inner wall of the housing. The deflection gear meshes with the toothed gear. The ring rack is fixedly mounted on the outer wall of the visible spraying hose. The forward drive gear and the toothed gear are perpendicular to each other. Each tooth on the ring rack is an independent circular tooth. Both the deflection gear and the toothed gear are in a toothed state, effectively limiting the rotation angle of the toothed gear during rotation. Both the forward drive gear and the deflection gear are driven by a motor.

[0008] Furthermore, the visualized spraying hose includes a snake-like joint section, a main pipe section structure, and a spraying end hose. The main pipe section structure slides horizontally within the housing. One end of the snake-like joint section is hinged to the main pipe section structure, and the spraying end hose is hinged to the other end of the snake-like joint section. A sliding groove is provided on the outer wall of the main pipe section structure, and a sliding block is provided on the inner wall of the toothed gear. The sliding block engages and slides within the sliding groove. The main pipe section structure is a thick-walled hollow tube. Rope grooves A and B are also provided on the side walls of the main pipe section structure, with rope grooves A and B arranged on opposite sides of the center.

[0009] Furthermore, the simulated snake bone joint segment is composed of multiple groups of joints, with adjacent groups of joints hinged together, and a pin is provided at the hinge point. Each joint has a lug (with a hole) at one end and a groove (with a hole) at the other end, through which a pin is passed to form a hinge, ensuring that deflection is prioritized rather than shortening when the rope is pulled. Each joint has a small hole at its center that penetrates both the front and rear walls, with rope grooves A and B placed at equal distances on both sides of the small hole. The edges of the joints are all chamfered to prevent the antibacterial sleeve from being caught when the joints rotate.

[0010] Furthermore, the spraying end hose is a straight pipe with a rounded front end. The spraying end hose has a channel that passes through the pipe. The rope groove A and rope groove B are respectively provided with pull rope A and pull rope B. Pull rope A and pull rope B are fixedly connected to the spraying end hose. The two connection points are located on both sides of the channel. When one of the pull ropes A and B is pulled, the other is in a relaxed state. Under the action of the pull rope, the snake bone joint segment bends, causing the spraying end hose to rotate.

[0011] Furthermore, the two sets of hinge points, rope groove A and rope groove B between the joints are evenly arrayed on the joint with the joint's dot as the center.

[0012] Furthermore, a control terminal assembly is provided inside the housing. A three-way connector is provided in the channel at the center of the snake-bone joint section, the main pipe section structure, and the spraying end hose. One end of the three-way connector is fixed inside the spraying end hose, and the end of the three-way connector is provided with a camera, a supplementary light bulb, and a spray nozzle. The three-way connector consists of a hose for delivering medicine, a power-carrying wire, and a data cable for transmitting camera data. The length of the nozzle is greater than the height of the camera and the bulb. When the antibacterial sleeve is placed over the spraying end hose, it will not affect the independence between the camera, supplementary light, and spraying functions.

[0013] Furthermore, the housing is also equipped with a reel A and a reel B, on which pull rope A and pull rope B are wound respectively, and both reels A and B are driven by a motor. The housing is equipped with a water pump, and the medicine delivery hose in the three-way connector is connected to the pump. The bottom wall of the pump is equipped with a coiled water suction hose.

[0014] Furthermore, an internal threaded interface is provided on the bottom wall of the housing. The internal threaded interface is located below the pump. The internal threaded interface can be threaded to connect a medicine bottle and a baffle with external threads. When the water suction hose is placed into the medicine bottle, the medicine can be effectively drawn. When the medicine is not needed, the internal threaded interface is sealed by the external threaded baffle.

[0015] Furthermore, the connection between the antibacterial sleeve and the top of the flat-mouth structure of the front inlet component is provided with an adsorption groove. Magnets are provided in both the adsorption groove and the connection part of the antibacterial sleeve for fixing the antibacterial sleeve. The front end of the antibacterial sleeve is a transparent plastic anti-pollution sheet with a spraying slot reserved for the spray nozzle. The inner wall of the front end of the antibacterial sleeve is provided with adhesive to fix the antibacterial sleeve to the spraying end hose. When the spraying end hose moves, the antibacterial sleeve expands and contracts accordingly. The antibacterial sleeve is made of rubber material with good tensile properties.

[0016] Furthermore, buttons are provided on the outer wall of the housing, and an array of buttons is located on the side wall of the handheld component. An energy storage battery is provided inside the housing. Pressing the buttons can send commands to the control terminal component to drive the electric device to work.

[0017] This solution provides a visual oral sprayer, which has the following beneficial effects: (1) This application sets up a visual spraying hose, which includes a snake-like joint segment, a main pipe structure and a spraying end hose. The snake-like joint segment is made of multiple sets of joints hinged together, and pull rope A and pull rope B are respectively set in rope groove A and rope groove B. With the drive of pulley A and pulley B, the spraying end hose can be flexibly bent. At the same time, a three-way connecting wire is set in the hole at the center of the snake-like joint segment, the main pipe structure and the spraying end hose. The end part integrates a camera, a supplementary light bead and a spraying nozzle. Combined with the display, the image inside the oral cavity is displayed in real time, so that the operator can accurately locate the lesion area for spraying, effectively avoiding the risk of poor treatment effect or damage caused by blind operation. (2) This application sets the front inlet component of the housing as a conical structure with a flat top, which can naturally support the teeth according to the size of the patient's mouth opening and closing, and prevent the teeth from closing due to stress during the spraying process and damaging the equipment; at the same time, the antibacterial sleeve is attached to the outer wall of the visual spraying hose, and it is fixed to the front inlet component by the magnet in the adsorption slot. The front end is equipped with a transparent plastic anti-pollution sheet and a spraying slot, which not only ensures the hygiene isolation during the spraying process and avoids cross-infection, but also allows the spraying end hose to move freely inside the antibacterial sleeve, and realizes the safe operation of visual spraying under the premise of ensuring sealing.

[0024] The housing 1 includes a handheld component 6, an end-limiting component 7, and a front-end entry component 8. The handheld component 6 is engaged with the transmission assembly 4. The end-limiting component 7 is fixedly mounted on the handheld component 6, and the bottom wall of the handheld component 6 is coplanar with the bottom wall of the end-limiting component 7.

[0026] The visual spraying hose 5 includes a snake-like joint section 13, a main pipe section structure 14, and a spraying end hose 15. The main pipe section structure 14 slides horizontally within the housing 1. One end of the snake-like joint section 13 is hinged to the main pipe section structure 14, and the spraying end hose 15 is hinged to the other end of the snake-like joint section 13. A sliding groove 16 is provided on the outer wall of the main pipe section structure 14, and a sliding block 17 is provided on the inner wall of the toothed gear 12. The sliding block 17 engages and slides within the sliding groove 16. The main pipe section structure 14 is a thick-walled hollow tube. Rope grooves A18 and B19 are also provided on the inner side wall of the main pipe section structure 14. Rope grooves A18 and B19 are located on both sides of the axis.

[0027] The snake-like joint segment 13 is composed of joints 20. Two adjacent groups of joints 20 are hinged together, and a pin is provided at the hinge point. Each joint 20 has a small hole at its center that penetrates the front and rear walls. Rope grooves A18 and B19, which are equidistant from each other, are placed on both sides of the small hole. The edges of the joints 20 are all designed with a chamfered structure.

[0028] The spraying end hose 15 is a straight pipe with a rounded front end. The spraying end hose 15 has a channel that passes through the pipe. The rope groove A18 and the rope groove B19 are respectively equipped with a pull rope A21 and a pull rope B22. Both pull ropes A21 and B22 are fixedly connected to the spraying end hose 15. The two connection points are set on both sides of the channel.

[0029] Two sets of hinge points, rope grooves A18 and B19 between joints 20 are evenly arrayed on joint 20 with the dot of joint 20 as the center.

[0030] The housing 1 contains a control terminal component 23. A three-way connector 24 is installed in the hole at the center of the snake-bone joint section 13, the main pipe section structure 14, and the spraying end hose 15. One end of the three-way connector 24 is fixed inside the spraying end hose 15, and the end of the three-way connector 24 is equipped with a camera, a supplementary light bulb, and a spray nozzle. The three-way connector 24 consists of a hose for delivering medicine, a power wire, and a data cable for transmitting camera data. The length of the nozzle is greater than the height of the camera and the bulb.

[0031] Inside the housing 1, there are also reels A25 and B26. Pull ropes A21 and B22 are wound on reels A25 and B26 respectively. Both reels A25 and B26 are driven by motors. Inside the housing 1, there is a water pump 27. The medicine delivery hose in the three-way connector 24 is connected to the pump 27. The bottom wall of the pump 27 is equipped with a coiled water suction hose 28.

[0032] An internal threaded interface 32 is provided on the bottom wall of the housing 1, and the internal threaded interface 32 is located below the pump 27.

[0033] The antibacterial sleeve 3 and the front inlet component 8 are connected at the top of the flat structure with an adsorption slot 29. Magnets are provided in both the adsorption slot 29 and the connection part of the antibacterial sleeve 3 to fix the antibacterial sleeve 3. The front end of the antibacterial sleeve 3 is a transparent plastic anti-pollution sheet 30. The anti-pollution sheet 30 is provided with a spraying slot 31 reserved for the spraying head. The inner wall of the front end of the antibacterial sleeve 3 is provided with adhesive to fix the antibacterial sleeve 3 to the spraying end hose 15. The antibacterial sleeve 3 is made of rubber.

[0034] Buttons are provided on the outer wall of the housing 1, and the button array is located on the side wall of the handheld component 6. A battery for energy storage is provided inside the housing 1.

[0035] In practical use, an antibacterial sleeve 3 is put on the outer wall of the visual spraying hose 5. The sleeve opening of the antibacterial sleeve 3 is inserted into the adsorption slot 29 on the front inlet component 8. The adsorption slot 29 and the magnet on the antibacterial sleeve 3 are attracted to each other. The adhesive on the inner wall of the front end of the antibacterial sleeve 3 is stuck to the top of the spraying end hose 15. The spraying nozzle on the spraying end hose 15 passes through the spraying slot 31 on the anti-pollution sheet 30. Remove the baffle with external threads at the bottom of the housing 1, open the internal thread interface 32, put the coiled water suction hose 28 into the medicine bottle, and then thread the medicine bottle onto the internal thread interface 32. Rotate monitor 2 and adjust it to an angle that is convenient for your eyes to view; When the power is turned on, the operation button can send operation commands to the control terminal component 23 to control the operation of each device in the device. Insert the visual spraying hose 5, which has been covered with the antibacterial sleeve 3, into the oral cavity. The upper and lower jaws bite the front inlet component 8. Depending on the size of the opening, the position and depth of the upper and lower jaws biting the tapered front inlet component 8 are different. The front inlet component 8 effectively prevents the upper and lower jaws from closing under stress during the spraying process, which could damage the visual spraying hose 5. The visual spraying hose 5 enters the oral cavity, and the camera and LED at the front end of the spraying hose 15 operate automatically. The LED provides supplementary lighting for the camera. Based on the approximate location of the wound in the oral cavity, the angle of the housing 1 entering the oral cavity can be manually adjusted so that the spray nozzle is directly facing the lesion area. When adjusting the casing 1 still fails to align the nozzle directly with the lesion, adjust the direction of rotation of the snake-like joint segment 13 according to the angle and orientation displayed on the monitor 2. Taking a lesion area in the upper right of the oral cavity as an example: The motor controls the deflection gear 11 to rotate, which drives the toothed gear 12 to rotate, causing the main section structure 14 to rotate, and the hinge point between the joints 20 in the snake bone joint section 13 changes the angle with the horizontal plane. The tightening of a rope depends on its position. Taking rope A21 on the right as an example, with the main section structure 14 already rotated, the spool A25 rotates, and part of rope A21 is wound onto the spool A25. The length of rope A21 remaining inside the visual spraying hose 5 is reduced, and the spool B26 where rope B22 is located rotates in the opposite direction. The length of rope B22 inside the visual spraying hose 5 is increased, and the bending of the snake bone joint section 13 is mainly achieved by the pulling of rope A21. Once the spray nozzle is displayed on monitor 2 as being directly aimed at the lesion, pump 27 operates, drawing the medication from the bottle into the nozzle and treating the lesion. When the length of the visual spray hose 5 is insufficient, the forward drive gear 9 rotates, causing the main pipe section structure 14 connected to the ring rack 10 to slide outward inside the housing 1, thereby approaching the diseased area in the oral cavity for easy observation and spraying. When the toothed gear 12 drives the main section structure 14 to rotate horizontally, the ring rack 10 does not affect the rotation of the main section structure 14. The equipment is compact and easy to store. The external antibacterial cover and medicine bottle can be removed and replaced at any time to ensure that each spraying will not cause equipment contamination or wound damage.
