Description

Technical Field

[0001] This invention relates to the field of oral medical device technology, and in particular to an oral medication application device. Background Technology

[0002] In the treatment of oral diseases, existing medication application devices suffer from problems such as difficulty in positioning, cumbersome operation, and poor compatibility with different drug types. They also face the challenge of drug loss due to saliva rinsing. When medication is applied to the oral wound, continuous saliva secretion rapidly dilutes or washes it away, resulting in a short retention time and insufficient concentration of the active ingredient. This problem is particularly pronounced in cases requiring long-lasting effects, such as the treatment of oral ulcers and postoperative wounds. Currently, traditional medication application methods lack a physical protective structure for the drug, requiring frequent reapplication by healthcare professionals to maintain efficacy. This not only increases patient discomfort but also reduces treatment efficiency. Summary of the Invention

[0003] In view of the problems existing in the prior art, the present invention is proposed.

[0004] To solve the above-mentioned technical problems, the present invention provides the following technical solution: an oral medication application device, which includes a main body component, including a handheld spray gun;

[0005] The motion component includes an inner pipe installed at the end of a handheld spray gun, the outer wall of which is provided with an outer pipe and supported by a support rib provided with the outer wall of the inner pipe, and the inner wall of the inner pipe is also provided with a turbine.

[0006] When the handheld spray gun is used to spray the medicine, the ointment pushes the turbine downward through the inner pipe, causing the combined plate at the end of the inner pipe to open. At the same time, the turbine is driven to rotate. When the turbine rotates, it drives the transmission component to move, causing the flip plate at the end of the outer pipe to flip. The gel delivered inside the handheld spray gun surrounds the ointment after it is sprayed. After the ointment is sprayed, the movable scraper in the receiving groove at the end of the outer pipe smooths the gel, so that it covers the outside of the ointment to form a protective layer.

[0008] In a preferred embodiment of the oral medication application device of the present invention, the second connector end is provided with a first gear, and the first gear meshes with a first rack disposed on the inner wall of the limiting frame and drives the first rack to move; the end of the first rack is provided with a round rod, and the end of the round rod extends to the inner wall of the limiting sleeve on the outer wall of the inner pipe; the outer wall of the round rod is provided with a sliding column, and the end of the sliding column extends into the spiral groove opened on the inner wall of the limiting sleeve and slides therewith.

[0009] In a preferred embodiment of the oral medication application device of the present invention, the outer wall of the inner tube is provided with a receiving cavity, the transmission component includes a toothed ring, the toothed ring is installed in the mounting block of the outer wall of the inner tube, and the end of the limiting sleeve is provided with a first bevel gear, which meshes with the toothed ring and drives the toothed ring to rotate.

[0010] In a preferred embodiment of the oral medication application device of the present invention, the toothed ring is provided with a connecting rod at its end and a rotating ring is movably provided at its end. The rotating ring is connected to a flip plate installed on the inner wall of the outer pipe. The outer wall of the flip plate is provided with a rotating shaft and the end of the rotating shaft extends to the outside of the outer pipe and is provided with a second gear. The second gear meshes with an amplifying gear set provided on the outer wall of the outer pipe and drives the amplifying gear set to rotate.

[0011] In a preferred embodiment of the oral medication application device of the present invention, the amplifying gear set has a second bevel gear at its end and the second bevel gear meshes with a transmission bevel gear at its end. The transmission bevel gear rotates under the influence of the second bevel gear and drives the output bevel gear installed at the end of the external pipe to rotate.

[0012] In a preferred embodiment of the oral medication application device of the present invention, a third gear is provided on the outer wall of the output bevel gear and the third gear is located in a receiving groove opened in the inner wall of the outer pipe. The third gear meshes with an arc-shaped rack provided on the inner wall of the receiving groove and drives the arc-shaped rack to slide inside the receiving groove. A movable scraper is also connected to the inner wall of the arc-shaped rack and the movable scraper slides together with the arc-shaped rack.

[0013] In a preferred embodiment of the oral medication application device of the present invention, the outer wall of the first connector is further fitted with a limiting ring and the end of the limiting ring is provided with a second elastic element, the outer wall of the limiting ring is hinged with a straight rod and the end of the straight rod is hinged with a slider, the outer wall of the slider is provided with a limiting plate and the end of the limiting plate extends to the inner wall of the limiting groove opened in the inner wall of the limiting frame and slides therewith.

[0014] In a preferred embodiment of the oral medication application device of the present invention, the inner wall of the inner channel is further provided with a turntable and the end face of the turntable is provided with an arc groove, the end of the slider is provided with a limiting post and the end of the limiting post extends to the inner wall of the arc groove and slides therewith.

[0015] In a preferred embodiment of the oral medication application device of the present invention, the turntable end face is provided with a combination plate and the combination plate end face is provided with a protruding post. The end of the protruding post extends into a movable groove opened on the other end face of the turntable and slides therewith. A fixed plate is provided inside the inner pipe. The other end of the protruding post extends into a straight groove opened on the end face of the fixed plate and slides therewith.

[0016] The beneficial effects of this invention are as follows: The inner and outer channels of this invention adopt a nested structure, which allows the gel to be squeezed out around the drug without interference between them. At the same time, during the delivery of the ointment, by pushing the turbine downward and rotating, the combined plate is first triggered to open and deliver the drug. Then, the flipping plate opens and the gel falls around the drug through the gel channel. The amount of gel delivered is proportional to the amount of drug used. After the drug delivery is completed, during the turbine reset process, the gel around the drug is smoothed by the movable scraper, so that it covers the upper surface of the drug and forms a protective film that isolates saliva, prolonging the drug retention time, reducing the frequency of medication replenishment, and improving the therapeutic effect.

[0031] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0032] Example 1

[0033] Reference Figures 1-5 This is the first embodiment of the present invention, which provides an oral medication application device.

[0034] Specifically, the main component 100 includes a handheld spray gun 101;

[0035] The motion component 200 includes an inner pipe 201 installed at the end of the handheld spray gun 101. An outer pipe 202 is provided on the outer wall of the inner pipe 201 and is supported by a support rib 2011 provided with the outer wall of the inner pipe 201. A turbine 203 is also provided on the inner wall of the inner pipe 201.

[0036] When the handheld spray gun 101 is used to spray the medicine, the ointment pushes the turbine 203 down through the inner pipe 201, causing the combined plate 208 at the end of the inner pipe 201 to open. At the same time, the turbine 203 is driven to rotate. When the turbine 203 rotates, it drives the transmission component to move, causing the flip plate 3021 at the end of the outer pipe 202 to flip. The gel delivered inside the handheld spray gun 101 surrounds the ointment after it is sprayed. After the ointment is sprayed, the movable scraper 306 in the receiving groove 2021 at the end of the outer pipe 202 smooths the gel, so that it covers the outside of the ointment to form a protective layer.

[0037] When the end of the handheld spray gun 101 enters the patient's mouth, pulling the trigger causes the ointment inside the drug storage cylinder and the gel in the gel storage tank to move outward through the inner pipe 201 and the outer pipe 202. The inner pipe 201 is a drug delivery channel installed inside the outer pipe 202 and fixedly supported by the support rib 2011.

[0038] When the ointment-like drug moves inside the inner pipe 201, it first pushes the turbine 203 downward. The side of the turbine 203 moves downward along the inner wall of the inner pipe 201. When the side of the turbine 203 is lower than the flow channel 2013, the drug moves downward along the side of the turbine 203, while simultaneously pushing the turbine 203 to rotate above the limiting frame 204. The limiting frame 204 is a shell fixed inside the inner pipe 201. The shell limits the turbine 203 and also prevents the drug from entering the interior of the shell.

[0039] The turbine 203 first pushes the combined plate 208 inside the inner pipe 201 to open and allow the drug to flow out. Then, when it rotates, the movement of the transmission component drives the flipping plate 3021 at the bottom of the outer pipe 202 to flip. At this time, the gel surrounds the drug through the gap of the flipping plate 3021, protecting the drug and preventing it from flowing around in the oral cavity. The transmission component will also drive the movable scraper 306 in the receiving groove 2021 to move. The movable scraper 306 work together to smooth the gel, so that the gel evenly covers the surface of the drug and forms a thin film layer, avoiding the washing away of the drug by saliva in the oral cavity, which would result in a short retention time of the drug's effective ingredients and insufficient concentration.

[0040] Example 2

[0041] Reference Figures 3-8 This is the second embodiment of the present invention, which is implemented based on the previous embodiment.

[0042] Specifically, a limiting frame 204 is provided on the inner wall of the inner pipe 201, a first connector 2031 is provided at the end of the turbine 203 and the end of the first connector 2031 extends into the limiting frame 204, a second connector 2043 is provided on the inner wall of the limiting frame 204 and the second connector 2043 is opposite to the first connector 2031, and a first elastic element 2032 is provided inside the first connector 2031 for pushing the first connector 2031 and the second connector 2043 to separate.

[0043] The limiting frame 204 is fixed inside the inner pipe 201. The outer shell effectively prevents the drug from entering the limiting frame 204. The bottom position of the first connector 2031 on the lower surface of the turbine 203 is located inside the limiting frame 204, opposite to the position of the second connector 2043 inside the limiting frame 204. However, due to the influence of the first elastic element 2032, the two do not contact each other in the initial state.

[0044] When the turbine 203 moves downwards due to the push of the drug inside the inner pipe 201, the lower surface of the turbine 203 is pressed against the upper surface of the limiting frame 204, and at the same time the first connector 2031 and the second connector 2043 are engaged, preparing for the subsequent rotation of the second connector 2043.

[0045] Preferably, the second connector 2043 is provided with a first gear 2044 at its end, and the first gear 2044 meshes with a first rack 2045 provided on the inner wall of the limiting frame 204 and drives the first rack 2045 to move. The first rack 2045 is provided with a round rod 2046 at its end, and the end of the round rod 2046 extends to the inner wall of the limiting sleeve 205 on the outer wall of the inner pipe 201. The outer wall of the round rod 2046 is provided with a sliding column 2047, and the end of the sliding column 2047 extends into the spiral groove 2052 opened on the inner wall of the limiting sleeve 205 and slides with it.

[0046] The second connector 2043 is fixedly installed inside the limiting frame 204. A first gear 2044 is coaxially connected below the second connector 2043. The first gear 2044 moves synchronously with the second connector 2043 and meshes with the first rack 2045. Figure 6 As shown, the first rack 2045 is symmetrically arranged on both sides of the first gear 2044, and the two sections extend from the side of the limiting frame 204 into the interior of the receiving cavity 2012. When the first gear 2044 rotates with the second connector 2043, it drives the two first racks 2045 to move synchronously.

[0047] The outer wall of the inner pipe 201 is provided with a receiving cavity 2012. The transmission component includes a gear ring 301, which is installed in the mounting block 2014 on the outer wall of the inner pipe 201. The end of the limiting sleeve 205 is provided with a first bevel gear 2051, which meshes with the gear ring 301 and drives the gear ring 301 to rotate.

[0048] The mounting block 2014 array has multiple inner pipes 201 on their outer surfaces. The toothed ring 301 is installed and fixed by the mounting block 2014, so that the toothed ring 301 can rotate inside the accommodating cavity 2012.

[0049] The limiting sleeve 205 is installed inside the accommodating cavity 2012 and is restricted from moving. When the first rack 2045 drives the sliding column 2047 on the surface of the round rod 2046 to move linearly, the limiting sleeve 205 rotates inside the accommodating cavity 2012 through the spiral groove 2052. The first bevel gear 2051 on the outer side of the limiting sleeve 205 drives the lower gear ring 301 to rotate.

[0050] A connecting rod 3011 is provided at the end of the toothed ring 301, and a rotating ring 302 is movably provided at the end of the connecting rod 3011. The rotating ring 302 is connected to a flip plate 3021 installed on the inner wall of the outer pipe 202. A rotating shaft 3022 is provided on the outer wall of the flip plate 3021, and the end of the rotating shaft 3022 extends to the outside of the outer pipe 202 and is provided with a second gear 3023. The second gear 3023 meshes with an amplifying gear set 303 provided on the outer wall of the outer pipe 202 and drives the amplifying gear set 303 to rotate.

[0051] Among them, such as Figure 5 As shown, the connecting rod 3011 array has multiple rods on the lower surface of the toothed ring 301 and rotates with the toothed ring 301 on the outer surface of the inner pipe 201. Since the first rack 2045 has a limited movement distance on the inner wall of the limiting frame 204, the round rod 2046 pushes the third elastic element 2053 a limited distance. When the round rod 2046 stops moving inside the limiting sleeve 205, the limiting sleeve 205 and the first bevel gear 2051 stop rotating, and the connecting rod 3011 stops rotating with the toothed ring 301.

[0052] The connecting rod 3011 and the toothed ring 301 rotate a limited distance. Therefore, after the connecting rod 3011 drives the flipping plate 3021 to flip a certain angle inside the outer pipe 202, it stops flipping and allows the flipping plate 3021 to open and allow the gel to flow downward.

[0053] Meanwhile, a rotating shaft 3022 is provided on the outside of the flip plate 3021 on one side. The rotating shaft 3022 rotates with the flip plate 3021 and drives the second gear 3023 located outside the outer pipe 202 to rotate. When the second gear 3023 rotates, it drives the amplifying gear set 303 meshing with it to rotate.

[0054] The amplifying gear set 303 has a second bevel gear 3031 at its end, and the second bevel gear 3031 is meshed with a transmission bevel gear 304. The transmission bevel gear 304 rotates under the influence of the second bevel gear 3031 and drives the output bevel gear 305 installed at the end of the external pipe 202 to rotate.

[0055] Among them, the amplifying gear set 303 is used to amplify the number of rotations of the second gear 3023. The second gear 3023 rotates half a turn with the rotating shaft 3022, and after passing through the amplifying gear set 303, it drives the second bevel gear 3031 below to rotate multiple times.

[0056] The transmission bevel gear 304 is installed below and meshes with the second bevel gear 3031. Due to the transmission ratio, the transmission bevel gear 304 will further amplify the number of rotations of the second bevel gear 3031 and eventually transmit the power to the output bevel gear 305, so that the output bevel gear 305 drives the third gear 3051 at the bottom to rotate.

[0057] Preferably, the outer wall of the output bevel gear 305 is provided with a third gear 3051, and the third gear 3051 is located in the receiving groove 2021 opened in the inner wall of the outer pipe 202. The third gear 3051 meshes with the arc-shaped rack 3061 provided in the inner wall of the receiving groove 2021 and drives the arc-shaped rack 3061 to slide inside the receiving groove 2021. The inner wall of the arc-shaped rack 3061 is also connected to a movable scraper 306, and the movable scraper 306 slides together with the arc-shaped rack 3061.

[0058] Two movable scrapers 306 are symmetrically arranged and installed inside the receiving groove 2021. The bottom ends of the movable scrapers 306 are hinged together, and the movable scrapers 306 are connected to the arc-shaped racks 3061. There are also two arc-shaped racks 3061, which are located on the upper and lower sides of the third gear 3051 respectively. When the third gear 3051 rotates, the two arc-shaped racks 3061 move synchronously relative to each other and drive the movable scrapers 306 to move inside the receiving groove 2021, smoothing the gel around the drug and covering it to form a protective film.

[0059] In summary, during use, when the ointment flows inside the inner pipe 201, it will first contact the turbine 203. The thrust will cause the turbine 203 to overcome the resistance of the first elastic element 2032 and move downward until the turbine 203 is pressed against the upper surface of the limiting frame 204. At this time, the first connector 2031 and the second connector 2043 are engaged. Afterward, when the medicine continues to flow, it will drive the turbine 203 to rotate, and through the first connector 2031, it will drive the first gear 2044 coaxial with the second connector 2043 to rotate. The first racks 2045 on both sides of the meshing move in opposite directions in a straight line.

[0060] When the first rack 2045 moves to both sides, the top round rod 2046 drives the sliding column 2047 to slide in the spiral groove 2052 of the limiting sleeve 205, converting the linear motion of the first rack 2045 into the rotation of the limiting sleeve 205. When the first bevel gear 2051 at the end of the limiting sleeve 205 rotates with the limiting sleeve 205, it drives the lower gear ring 301 to rotate. The gear ring 301 drives the rotating ring 302 to deflect through the connecting rod 3011, causing the flip plate 3021 on the inner wall of the outer pipe 202 to flip, opening the gel outlet, and the gel begins to spray outward around the ointment.

[0061] As the flip plate 3021 flips, it drives the external second gear 3023 to rotate via the rotating shaft 3022. The amplifying gear set 303 meshes with the second gear 3023 and rotates, amplifying the number of rotations of the second gear 3023. The second bevel gear 3031 at the bottom of the amplifying gear set 303 meshes with the transmission bevel gear 304, changing the transmission direction and driving the output bevel gear 305. The third gear 3051 on the outer wall of the output bevel gear 305 drives the arc-shaped rack 3061 in the receiving groove 2021 to slide. The arc-shaped racks 3061 on both sides drive the movable scraper 306 to move relative to each other, evenly spreading the sprayed gel into a thin film, covering the outside of the ointment to form a protective layer.

[0062] Example 3

[0063] Reference Figure 5 , Figure 6 , Figure 9 and Figure 10 This is the third embodiment of the present invention, which is implemented based on the previous embodiment.

[0064] Specifically, the outer wall of the first connector 2031 is also fitted with a limiting ring 2041 and the end of the limiting ring 2041 is provided with a second elastic element 2033. The outer wall of the limiting ring 2041 is hinged with a straight rod 2042 and the end of the straight rod 2042 is hinged with a slider 206. The outer wall of the slider 206 is provided with a limiting plate 2061 and the end of the limiting plate 2061 extends to the inner wall of the limiting groove 2063 opened in the inner wall of the limiting frame 204 and slides with it.

[0065] In the initial state, the second elastic element 2033 pushes the limiting ring 2041 and the turbine 203 to be in the upper position inside the limiting frame 204. When the limiting ring 2041 is affected by the downward movement of the turbine 203, the straight rods 2042 on both sides will push the bottom slider 206 to move to both sides inside the limiting groove 2063.

[0066] Preferably, the inner wall of the inner pipe 201 is also provided with a turntable 207 and the end face of the turntable 207 is provided with an arc groove 2071, and the end of the slider 206 is provided with a limit post 2062 and the end of the limit post 2062 extends to the inner wall of the arc groove 2071 and slides with it.

[0067] The slider 206 is installed above the turntable 207. When the slider 206 moves to both sides inside the limiting frame 204, the limiting post 2062 at the bottom of the slider 206 slides inside the arc groove 2071, causing the turntable 207 to rotate inside the inner pipe 201.

[0068] Preferably, the turntable 207 has a combination plate 208 on its end face and a protrusion 2081 on its end face. The end of the protrusion 2081 extends into the movable groove 2072 opened on the other end face of the turntable 207 and slides therewith. The inner pipe 201 has a fixed plate 209 inside. The other end of the protrusion 2081 extends into the straight groove 2091 opened on the end face of the fixed plate 209 and slides therewith.

[0069] The combination plate 208 is installed between the turntable 207 and the fixed plate 209. The fixed plate 209 is fixed inside the inner pipe 201 and does not move. Therefore, when the turntable 207 rotates, the combination plate 208 moves above the fixed plate 209 through the sliding engagement between the moving groove 2072 on the lower surface of the turntable 207 and the protrusion 2081 on the surface of the combination plate 208. The combination plate 208 opens between the fixed plate 209 and the turntable 207, allowing the medicine in the inner pipe 201 to flow out.

[0070] In summary, during use, in the initial state, the second elastic element 2033 pushes the limiting ring 2041 and the turbine 203 upward, causing the first connector 2031 to separate from the second connector 2043, and the combination plate 208 closes to block the passage of the inner pipe 201.

[0071] When the ointment flows through the inner pipe, the thrust overcomes the resistance of the second elastic element 2033, driving the turbine 203 to move downward. The limiting ring 2041 moves downward synchronously with the turbine 203. When the limiting ring 2041 moves downward, the straight rods 2042 hinged on both sides of the limiting ring 2041 push the bottom slider 206 to slide to both sides in the limiting groove 2063. The limiting plate 2061 guides the slider 206 along the groove to ensure that the slider 206 moves smoothly.

[0072] The limiting post 2062 at the bottom of the slider 206 slides within the arc groove 2071 of the turntable 207, converting the linear motion of the slider 206 into the rotational motion of the turntable 207.

[0073] When the turntable 207 rotates, the movable groove 2072 on the lower surface of the turntable 207 slides with the protrusion 2081 of the combination plate 208. At the same time, the protrusion 2081 moves in the straight groove 2091 of the fixed plate 209. Since the fixed plate 209 is fixed, the rotation of the turntable 207 causes the protrusion 2081 to push the combination plate 208 to unfold around the central axis, forming an opening that allows the drug to flow out from the end of the inner pipe.

[0074] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
