Description

Technical Field

[0001] The invention relates to an oral medicine applicator, in particular to an oral medicine applicator, and belongs to the technical field of medical devices. Background Art

[0002] The oral cavity is composed of two lips, two cheeks, hard palate, soft palate, etc. When the lips and cheeks are punctured or bitten by teeth while eating, ulcers often occur due to bacterial infection. When ulcers occur, medicine is often applied to the location where the lesions occur.

[0003] After searching, Chinese patent number CN112494789A discloses a medical powder medicine oral applicator. The applicator head is designed to be flat so that it can cover the area where the medicine needs to be applied, making it easy to apply the medicine and evenly apply the medicine to the affected area. When the medicine needs to be applied, the rotating shaft is rotated, and the gear rotates along the large ring under the action of the rotating shaft. The piston rod moves in the medicine storage cartridge under the action of pressure, so that the medicine in the medicine storage cartridge is sprayed onto the affected area through the medicine outlet. However, the above patented product and traditional oral applicators all require the use of observation of photographic images to find the correct application position. For oral ulcers, patients need to apply the medicine several times a day. When applying the medicine to themselves outdoors alone, there is no medium that can reflect images around them, and they cannot accurately find the application position by themselves, which is cumbersome and inconvenient. Summary of the Invention

[0004] The purpose of the present invention is to provide an oral medicine applicator in order to solve the above problems.

[0005] The present invention achieves the above-mentioned object through the following technical solutions: an oral medicine applicator, comprising a shell and a medicine container arranged in the middle of the shell, an auxiliary component and a medicine selection component are arranged between the shell and the medicine container, the auxiliary component is composed of an observation camera, a rotating component and a transmission component, the observation camera is horizontally placed on the top of the shell, the transmission component is composed of a rotating rod and a conveyor belt, one end of the observation camera is connected to the rotating rod, and the conveyor belt realizes the synchronous rotation of the rotating component and the rotating rod, when the rotating component rotates forward, the observation camera is rotated out from the top of the shell and unfolded to form an angle with the top of the shell, the unfolded observation camera faces the patient, and reflects the wound inside the oral cavity when the patient applies medicine;

[0006] When the rotating component rotates in the reverse direction, it drives the observation camera to return to its initial position;

[0007] The upper medicine selection component consists of an extrusion part and a pressing part. The extrusion part is provided with extrusion rods and extrusion blocks on both sides close to the medicine loading container. When the extrusion block is pressed, it will cause the extrusion rods on both sides close to the medicine loading container to bend. The sharp corners of the bend squeeze the medicine loading container inward, extruding the medicine stored inside the medicine loading container outward.

[0008] The pressing part consists of a piston and a pressing block arranged inside the medicine loading container. The pressing block drives the piston to move horizontally, pushing out the medicine inside the medicine loading container. The positions of the pressing block and the extrusion block are staggered, and this staggered arrangement can prevent accidental touching by the patient when applying medicine.

[0009] Preferably, the rotating component consists of a turntable and an eccentric block arranged on the turntable. The turntable is located on both sides at the bottom end of the outer shell. The eccentric block is arranged on the turntable and is far from the center of the turntable. The eccentric block is arranged at the 3 / 4 position of the radius of the turntable.

[0010] Preferably, the medicine loading container is arranged in the shape of a cylindrical syringe. The outer shell is sleeved outside the medicine loading container in a rectangular shape. Both ends of the medicine loading container penetrate through the outer shell. The pressing block and the extrusion block are both located at the same end outside the medicine loading container.

[0011] Preferably, one end of the extrusion rod far from the extrusion block can move back and forth inside the outer shell. A main shaft is provided at the bending position of the extrusion block. An expansion rod is arranged between the main shaft and the inside of the outer shell. When the extrusion block is squeezed, the expansion rod extends.

[0012] Preferably, the side of the outer shell is arranged in a shape like '乛'. The turntable is located on both sides at the bottom end of this '乛' shape. The protruding part at the bottom end of this '乛' shape is convenient for the thumb of the patient to hold接力夹持 (I'm not sure what this word means exactly, please check) when holding, improving the stability when the patient applies medicine.

[0013] Preferably, a funnel-shaped mounting cover is provided at one end of the medicine loading container far from the pressing block. A rotating component is arranged between the mounting cover and the medicine loading container. The rotating component drives the mounting cover to screw in and out at the end of the medicine loading container through forward and reverse rotation, realizing the installation and separation of the mounting cover, and enabling the medicine to be replenished and replaced through this position.

[0014] Preferably, the bottom end of the extrusion block is arranged in an arc shape. The inner diameter dimension of the arc inside the extrusion block is larger than the diameter dimension of the pressing block.

[0015] Preferably, grooves are provided at the positions of the rotating part and the rotating rod close to the conveyor belt. Corresponding meshing gears are arranged on the outside of the grooves and inside the conveyor belt.

[0016] Preferably, the angle formed between the observation camera and the top of the housing when the observation camera rotates is 0-120°.

[0017] The present invention has the following beneficial effects:

[0018] 1. By adding an observation lens, which can be a convex mirror or a convex aluminum-plated plastic film, it can reflect the image of the object. When the patient applies the medicine alone, the observation lens can be selectively rotated out and unfolded, so that the observation lens is aligned with the oral position, making it easier for the user to apply the medicine alone;

[0019] 2. For powdered drugs, press the extrusion block to bend the internal pressing rod against the two sides of the drug container, spraying the drug inside the drug container outward and applying it to the wound in the mouth. For liquid drugs, observe the film and squeeze the pressing block to move the piston inside the drug container to squeeze out the liquid drug to complete the drug application;

[0020] 3. The eccentric block is set at the 3 / 4 radius position of the turntable, close to the outside of the turntable, which significantly increases the length of the lever arm. Compared with applying force directly at the center of the circle, the required external force is greatly reduced, making adjustment more convenient.

[0021] 4. The invention can meet the needs of applying powdered and liquid medicines, and can independently select the application method according to the patient's usage habits. At the same time, the addition of an observation camera solves the problem that patients need to find something to observe when applying medicine, and the application operation can be carried out at any location.

[0031] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0032] Example 1:

[0033] Reference Figure 1-4 as well as Figure 6-7 , an oral medicine applicator, comprising an outer shell and a medicine container 1 arranged in the middle of the inner shell, an auxiliary component 2 and a medicine selection component 3 are provided between the outer shell and the medicine container 1, the auxiliary component 2 is composed of an observation photographic piece 202, a rotating component and a conveying component, the observation photographic piece 202 is placed horizontally on the top of the outer shell, the conveying component is composed of a rotating rod 203 and a conveying belt 204, one end of the observation photographic piece 202 is connected to the rotating rod 203, and the conveying belt 204 realizes the synchronous rotation of the rotating component and the rotating rod 203, when the rotating component rotates forward, the observation photographic piece 202 is rotated out from the top of the outer shell and unfolded, and forms an angle with the top of the outer shell, the unfolded observation photographic piece 202 faces the patient, and reflects the wound inside the oral cavity when the patient applies medicine, and when the rotating component rotates reversely, it drives the observation photographic piece 202 to return to its initial position.

[0034] The rotating assembly consists of a turntable 206 and an eccentric block 207 arranged on the turntable 206. The turntable 206 is located on both sides of the bottom end of the shell. The eccentric block 207 is arranged on the turntable 206, and the eccentric block 207 is away from the center of the turntable 206. The eccentric block 207 is arranged at 3 / 4 of the radius of the turntable 206.

[0035] like Figure 6As shown, the eccentric block 207 is set at the 3 / 4 position of the radius of the turntable 206, away from the center of the circle. The length of the lever arm is significantly increased. Compared with applying force directly at the center of the circle (where the lever arm is 0 and rotation is impossible), the external force required is greatly reduced. Although it does not reach the maximum lever arm, 3 / 4R is already close to the edge, and the external force is only 4 / 3 times that of the resistance (1 time at the edge). The labor-saving effect is close to the optimal solution, and at the same time, it avoids the inconvenience of operation caused by the eccentric block 207 exceeding the edge of the turntable 206.

[0036] The medicine loading container 1 is arranged in the shape of a cylindrical syringe, and the outer shell is sleeved on the outside of the medicine loading container 1 in a rectangular shape. Both ends of the medicine loading container 1 penetrate through the outer shell, and the pressing block 302 and the extrusion block 308 are both located at the same end outside the medicine loading container 1.

[0037] The side of the outer shell is arranged in a "乛" shape. The turntable 206 is located on both sides of the bottom end of the "乛" shape. The protruding part at the bottom end of the "乛" shape is convenient for the thumb to relay and hold when the patient holds it, improving the stability when the patient applies medicine.

[0038] As Figure 1 shown, the "乛" - shaped outer shell is in the shape of a gun. When the patient applies medicine with one hand, when the thumb rotates the eccentric block 207 on the turntable 206, the middle finger or the ring finger can hook the lower side of the "乛" - shaped outer shell, improving the holding stability.

[0039] At the position where the rotating part and the rotating rod 203 are close to the conveyor belt 204, there is a groove, and corresponding meshing gears are provided on the outside of the groove and inside the conveyor belt 204.

[0040] In this embodiment, it should be noted that: as Figure 6 shown, the turntable 206 is symmetrically arranged on both sides of the outer shell, and a placement groove 201 is provided at the top of the outer shell, and the observation and imaging member 202 is arranged inside the placement groove 201.

[0041] The observation and imaging member 202 is set as a convex mirror or a convex aluminized plastic film, which is thin in the center and thick at the edge, and will magnify the imaged object, magnify the position of the wound in the oral cavity, and help the patient find the wound position for medicine application operation.

[0042] The end of the observation camera 202 away from the mounting cover 4 is fixedly connected to the rotating rod 203. When the patient applies medicine, he can hold the medicine applying device with one hand and use his thumb to rotate the eccentric block 207 on the turntable 206. When the eccentric block 207 rotates, it drives the turntable 206 and the connecting rotating rod 205 to rotate. Through the mutually meshing gear connection, it drives the conveyor belt 204 and the rotating rod 203 to rotate, so that the observation camera 202 is rotated and unfolded from the placement groove 201, so that the reflection surface of the observation camera 202 originally facing the inside of the slot of the placement groove 201 is rotated upward and aligned with the side of the mounting cover 4. When the patient applies medicine, the expanded observation camera 202 can be used to observe the internal situation of the oral cavity to complete the medicine application at the wound position.

[0043] The angle formed between the observation camera 202 and the top of the housing when the observation camera 202 rotates is 0-120°.

[0044] When the observation photographic piece 202 is at 90° to the top of the shell, the observation photographic piece 202 is aimed at the nozzle for applying medicine, and the wound position on the upper side of the mouth, 90-120° can be used for wide-angle reflection and spatial extension, which is convenient for patients to find the correct position for applying medicine.

[0045] Example 2:

[0046] The difference from the first embodiment is that, referring to Figure 1-5 as well as Figure 8 This embodiment further has the following features: the medicine selection assembly 3 is composed of an extrusion component and a pressing component. The extrusion component is provided with extrusion rods 305 and extrusion blocks 308 on both sides of the medicine container 1. When the extrusion blocks 308 are pressed, the extrusion rods 305 on both sides of the medicine container 1 are bent. The sharp corners of the bend press the medicine container 1 inward, squeezing the medicine stored in the medicine container 1 outward.

[0047] The pressing component consists of a piston 301 and a pressing block 302 arranged inside the medicine container 1. The pressing block 302 drives the piston 301 to move in the horizontal direction to push the medicine inside the medicine container 1 out. The positions of the pressing block 302 and the squeezing block 308 are staggered. This staggered arrangement can prevent patients from accidentally touching the medicine when applying the medicine.

[0048] The end of the extrusion rod 305 away from the extrusion block 308 can move back and forth inside the shell. A main shaft 309 is provided at the bending position of the extrusion block 302, and a telescopic rod 307 is provided between the main shaft 309 and the inside of the shell. When the extrusion block 305 is squeezed, the telescopic rod 307 extends.

[0049] The bottom end of the extrusion block 308 is arranged in an arc shape, and the inner diameter of the arc of the extrusion block 308 is larger than the diameter of the pressing block 308 .

[0050] like Figure 2 as well as Figure 4 It can be seen that the bottom end of the pressing block 308 is arranged in an arc shape, and the inner diameter of the arc of the pressing block 308 is larger than the diameter of the pressing block 302.

[0051] In this embodiment, it should be noted that: Figure 3-4 As shown, the piston 301 is located inside the medicine container 1 and is connected to the pressing block 3. By pressing the pressing block 3, the piston 301 is driven to move inside the medicine container 1 to squeeze the medicine inside out.

[0052] A main shaft 309 is provided at the connection between the two extrusion rods 305 located on the same side of the charging container 1. The bottom end of the main shaft 309 is fixedly connected to the outside of the charging container 1. A telescopic rod 307 is provided between the top of the main shaft 309 and the inside of the shell. Springs 306 are provided between the two sides of the telescopic rod 307 close to the main shaft 309 and the extrusion rod 305. A rotating shaft 304 is provided between the extrusion rod 305 close to the extrusion block 308 and the extrusion block 308. The end of the extrusion rod 305 away from the extrusion block 308 is movably engaged with the inside of the shell. A slot for allowing the extrusion rod 305 to move is provided in the shell, and a rotating shaft 304 is provided between the rotating shaft 304 and the extrusion rod 305.

[0053] like Figure 3-4 As shown, when applying powdered medicine, or habitually using the spraying habit, you can use a finger to press the squeezing block 308 and squeeze it toward the medicine container 1, driving the movable rod 303 to move inside the shell. Due to the limitation of the telescopic rod 307, when the movable rod 303 squeezes the squeezing rod 305, the squeezing rod 305 on the side close to the mounting cover 4 moves on the card slot inside the shell, and the squeezing rod 305 on the other side rotates around the rotating shaft 304. The two squeezing rods 305 are bent to each other to form an angle, the telescopic rod 307 extends, and the spring 306 contracts, so that the main shaft 309 is pressed downward to squeeze the medicine container 1, and the medicine container 1 is deformed, squeezing the foreign objects inside the medicine container 1 outward to achieve medicine application.

[0054] The medicine container 1 is made of PP plastic, which has good chemical stability, heat resistance, corrosion resistance, is non-toxic and odorless, has high mechanical strength, is not easy to break, and can be sterilized by various methods such as high pressure sterilization and ethylene oxide sterilization, which can meet the strict hygiene requirements of medical devices. At the same time, its cost is relatively low, it is easy to process and shape, and is suitable for large-scale production.

[0055] After the squeezing block 308 is released, the squeezing rods 305 on both sides are expanded to both sides under the reset of the spring 306, and the telescopic rod 307 is retracted, driving the main shaft 309 upward to drive the medicine container 1 to recover.

[0056] When applying liquid medicine, a transparent observation window 5 is provided at one end of the top of the shell near the mounting cover 4, and a scale is provided on the medicine container 1. The liquid capacity placed inside the medicine container 1 can be observed through the transparent observation window 5, which facilitates accurate medicine application. Similarly, the scale and transparent observation window 5 can also read powder medicine. Pressing the pressing block 302 drives the piston 301 to move, and the piston 301 squeezes the medicine stored inside out to complete the medicine application.

[0057] The pressing block 308 is arranged in an arc shape and staggered with the pressing block 302, so that when the patient applies the medicine with one hand, the thumb and middle finger fix the device body, and the index finger selectively presses the pressing block 302 or the squeezing block 308 to select the medicine application method.

[0058] Example 3:

[0059] Reference Figure 1-5 Compared with the first and second embodiments, in this embodiment: a funnel-shaped mounting cover is provided at the end of the medicine-filling container away from the pressing block, and a rotating assembly is provided between the mounting cover and the medicine-filling container. The rotating assembly drives the mounting cover to rotate in and out at the end of the medicine-filling container through forward and reverse rotation, thereby realizing the installation and separation of the mounting cover, so that the medicine can be replenished and replaced through this position.

[0060] In this embodiment, it should be noted that: the mounting cover 4 is funnel-shaped and has threads, so that the mounting cover 4 can be quickly disassembled and installed, and the medicine can be loaded by unscrewing the mounting cover 4.
