[0017] The beneficial effects of the present invention: (1)During use, the staff quickly inputs anesthetic ointment into the medicine storage barrel through the feeding pipe head. There is no need to reverse the operation of the device or disassemble the components, which saves time and effort. The anesthetic ointment is guided by the support ring plate and through the cooperation of the first side plate and the bent guide plate, so that the anesthetic ointment finally forms a strip-shaped trajectory with a fixed width for extension, facilitating the doctor to fully and accurately cover the application site. By rotating the limit guide plate to adjust the distance between its side and the end edge of the bent guide plate, and through the threaded socket of the first sleeve and the first screw, the distance between the side of the limit guide plate and the bent guide plate is accurately adjusted, thereby accurately adjusting the thickness when outputting the ointment, facilitating the one-time coating of the anesthetic ointment on the affected area, avoiding the pollution of the device or the affected area caused by reciprocating movement, and at the same time facilitating the coating of a fixed-thickness anesthetic ointment or other ointments on a large affected area, ensuring that the ointments take effect simultaneously, avoiding the invalidation of some areas due to reasons such as too fast drying, and maintaining the coating efficiency and the synchronization rate of taking effect during large-scale coating; (2)During operation, the drive roller rolls on the patient's skin and is driven through the second rotating shaft, the third rotating shaft and the fourth bevel gear, thereby driving the bonded drive shaft to rotate. Subsequently, the second gear, the third gear, the first gear, the third bevel gear, the second bevel gear, the first rotating shaft, the first bevel gear and the drive gear ring are driven in sequence, so that the rate of the up and down movement of the piston plate corresponds to the rotation of the drive roller through continuous transmission, making the drive roller only used to contact the patient's skin surface for self-driving by reaction force, avoiding the problem that the ointment is over-lubricated and cannot roll when coating the ointment synchronously. At the same time, it can not only flexibly adjust the thickness of the output ointment, but also avoid the disconnection of the ointment output, ensuring the continuous output of a fixed quantity, fixed thickness and fixed width of ointment, so as to obtain the best conveying effect of the externally applied anesthetic ointment; (3)During operation, due to the cross-sectional shapes of the drive insert rod and the positioning insert rod, they can only slide by themselves and cannot rotate relative to the second screw. At the same time, through the engagement and separation of the drive insert rod and the positioning insert groove, the second screw and the support slider are locked or rotated. This can not only make the second sleeve stably push the second screw up and down when it is forced to rotate, but also make the second screw itself rotate and lift quickly under the rotation of the user. There is no need to perform a series of reverse transmission operations such as reverse rotation of the drive roller to move the piston plate upward, quickly preparing for refilling the ointment again. The whole does not need to be disassembled or assembled, and there is no need for a long preparation, improving the overall work efficiency. Multiple transmission ratios are formed by multiple groups of second gears and third gears, so that the drive roller can drive the second sleeve to rotate more turns at the same rotation speed, thereby moving the piston plate downward at a faster speed, meeting the requirements of a large conveying volume of special ointments, and ensuring that the ointment is continuously connected under the requirements of different thicknesses and different conveying volumes.

Detailed implementation manners

[0020] To further elaborate on the technical means and effects adopted by the present invention to achieve the intended invention purpose, the following will, in conjunction with the accompanying drawings and preferred embodiments, elaborate in detail on the specific implementation manner, structure, features and their effects of the present invention as follows.

[0021] Please refer to Figure 1-7 As shown: An external application anesthetic uniform dosing device, including a medicine storage barrel 101, a support ring plate 102 is installed at the lower end of the medicine storage barrel 101, and the medicine storage barrel 101 is in through connection with the support ring plate 102. First side plates 103 are installed on both sides of the support ring plate 102. A bent guide plate 104 is provided directly below the support ring plate 102 between the two first side plates 103. An elastic arc plate 112 is installed on one side of the support ring plate 102. A limit guide plate 105 is installed on one side of the elastic arc plate 112. A piston plate 106 is slidably sleeved inside the medicine storage barrel 101. A feed pipe head 107 is connected through the outside of the medicine storage barrel 101 above the limit guide plate 105. A first screw 108 is hinged to the lower part of the side surface of the feed pipe head 107. A support cylinder 109 is hinged to the middle of the limit guide plate 105. The upper outer periphery of the support cylinder 109 is rotatably connected to a support sleeve 110. A first sleeve 111 is installed at the upper end of the support sleeve 110. The first sleeve 111 is threadedly sleeved on the first screw 108. A limit slide bar 115 is installed at the inner bottom of the support cylinder 109. The axis of the first screw 108 is of a hollow structure, and the support cylinder 109, the first screw 108 and the limit slide bar 115 are in a sliding sleeve structure in sequence from the outside to the inside. A support roller 113 is installed at the bottom of the bent guide plate 104. The two sides and one end of the bent guide plate 104 are hermetically connected to one side of the first side plate 103 and the support ring plate 102 respectively, and a gap is maintained between the upper surface of the bent section at the other end of the bent guide plate 104 and the other side of the support ring plate 102. An adjustable gap is maintained between the upper surface of the other end of the bent guide plate 104 and the limit guide plate 105. A one-way valve 114 is installed inside the feed pipe head 107; When this embodiment works, the external application anesthetic ointment is contained in the medicine storage barrel 101, and the ointment is introduced into the cavity formed between the first side plate 103, the bent guide plate 104 and the limit guide plate 105 through the through connection of the support ring plate 102. Then, by rotating the first sleeve 111, the length of the first screw 108 extending out of the support cylinder 109 is adjusted, so as to adjust the rotation angle of the limit guide plate 105, thereby adjusting the distance length between the side of the limit guide plate 105 and the side of the bent guide plate 104, and finally adjusting the thickness of the output anesthetic ointment. At the same time, the piston plate 106 is pressed downwards, and a corresponding pressing speed is formed in cooperation with the overall moving speed, so that the device continuously outputs a quantitative, fixed-width and fixed-thickness anesthetic ointment while moving, and the thickness of the anesthetic ointment can be flexibly adjusted according to different requirements.

[0022] The top of the piston plate 106 is provided with a support slider 201. The top of the support slider 201 is provided with a second screw rod 202. The second screw rod 202 penetrates through the top of the medicine storage barrel 101. A second sleeve 204 is sleeved on the second screw rod 202 in a threaded manner. A first transmission box 207 is provided at the top of the medicine storage barrel 101. The second screw rod 202 penetrates through the first transmission box 207. The second sleeve 204 is rotatably connected to the first transmission box 207 through a second bearing 205. A transmission gear ring 206 is fixedly sleeved on the outer periphery of the second sleeve 204. A first support plate 208 is installed in the first transmission box 207. A first rotating shaft 209 is rotatably penetrated through the first support plate 208. A first bevel gear 210 and a second bevel gear 211 are respectively installed at both ends of the first rotating shaft 209. The first bevel gear 210 is meshed with the transmission gear ring 206; One end of the first transmission box 207 is provided with a second transmission box 215. A support rotating shaft 212 is installed on the inner side of the end of the first transmission box 207. A third bevel gear 213 and a first gear 214 are rotatably connected to the support rotating shaft 212. The third bevel gear 213 is meshed with the second bevel gear 211, and the third bevel gear 213 is fixedly connected to the first gear 214. A bonding transmission shaft 216 is rotatably connected to the middle part of the inner side of the second transmission box 215. A third transmission box 220 is installed at the lower part of the second transmission box 215. The lower end of the bonding transmission shaft 216 penetrates through the second transmission box 215 and the third transmission box 220, and the bonding transmission shaft 216 is rotatably connected to the second transmission box 215 and the third transmission box 220 through a clamping shaft sleeve 219; A second gear 217 is sleeved on the bonding transmission shaft 216 in a keyed and movable manner. A third gear 218 is arranged between the second gear 217 and the first gear 214, and the second gear 217, the third gear 218 and the first gear 214 are adjacent to each other in sequence and are meshed with each other; A second side plate 221 is installed on one side of the third transmission box 220. A transmission roller 222 is rotatably connected between the lower end of the third transmission box 220 and the second side plate 221. A second rotating shaft 223 is horizontally rotatably connected to the upper part of the inner side of the third transmission box 220. A third rotating shaft 224 is vertically rotatably connected to the lower part of the inner side of the third transmission box 220. Transmission is carried out between the lower end of the bonding transmission shaft 216 and the second rotating shaft 223, between the second rotating shaft 223 and the third rotating shaft 224, and between the third rotating shaft 224 and the rotating shaft of the transmission roller 222 through pairs of meshed fourth bevel gears 225. The third transmission box 220 is connected to the medicine storage barrel 101 through a support connecting frame 226; When this embodiment works, by rotating the second sleeve 204, the second screw rod 202 is pushed to move up and down, and then the support slider 201 and the piston plate 106 are pushed to move up and down, so as to limit the output amount of the anesthetic ointment. The transmission roller 222 rolls on the patient's skin, and is transmitted through the second rotating shaft 223, the third rotating shaft 224 and the fourth bevel gear 225, so as to drive the bonding transmission shaft 216 to rotate. The bonding transmission shaft 216 then drives the second gear 217, the third gear 218, the first gear 214, the third bevel gear 213, the second bevel gear 211, the first rotating shaft 209, the first bevel gear 210 and the transmission gear ring 206 in sequence. Thus, through continuous transmission, the moving speed of the piston plate 106 corresponds to the rotation of the transmission roller 222, so that the piston plate 106 can move down to output the ointment only when the transmission roller 222 rotates, and the faster the transmission roller 222 rotates, the faster the piston plate 106 moves down. Therefore, the moving speed of the device corresponds to the output speed of the ointment, preventing the ointment delivery from being disconnected and enabling continuous output of the ointment.

[0023] The support slider 201 is rotatably connected to the second screw rod 202 through the first bearing 203. A positioning groove 301 is formed at the top of the support slider 201. A transmission rod 302 is slidably inserted through the axis of the second screw rod 202. The lower end of the transmission rod 302 penetrates through the first bearing 203 and is fitted and sleeved in the positioning groove 301. A positioning rod 303 is installed at the top of the transmission rod 302. A positioning button 304 is installed at the top of the positioning rod 303. The positioning rod 303 is movably sleeved with the second screw rod 202. The cross sections of the positioning rod 303 and the transmission rod 302 are of a polygonal structure. In this embodiment, the cross sections of the positioning rod 303 and the transmission rod 302 are square. A spring bolt 305 is embedded on the side wall of the positioning rod 303. A spherical groove 306 is formed in the inner side of the top end of the second screw rod 202; When this embodiment is working, by pressing down the positioning button 304, the transmission insertion rod 302 passes through the first bearing 203 and is fitted into the positioning slot 301. The fixing between the second screw rod 202 and the support slider 201 is maintained by the fitting of the transmission insertion rod 302 and the positioning slot 301. Due to the limiting reaction that the support slider 201 and the piston plate 106 can only slide but not rotate, the second sleeve 204 can stably push the second screw rod 202 to move up and down when it is forced to rotate. When it is necessary to refill anesthetic ointment or other ointments again, the positioning button 304 is moved upward, and the positioning insertion rod 303 and the transmission insertion rod 302 move upward synchronously. The transmission insertion rod 302 is separated from the positioning slot 301. The positioning insertion rod 303 is limited by the fitting and clamping of the spring bolt 305 and the spherical groove 306, which facilitates the rotation of the second screw rod 202. At this time, the second sleeve 204 is stationary, and the second screw rod 202 moves upward as it rotates, and at the same time, it quickly drives the piston plate 106 to move upward above the feed pipe head 107, thus avoiding the redundant steps of reverse operation and quickly refilling the ointment again.

[0024] Fourth transmission boxes 401 are installed on both sides of the second transmission box 215. A fourth rotating shaft 402 is rotatably connected above the interior of the fourth transmission box 401. Third screw rods 403 are rotatably connected to both sides inside the fourth transmission box 401. An adjustment knob 404 is installed between the two fourth rotating shafts 402. A positioning slider 405 is threadedly sleeved on the third screw rod 403. Transmission sliders 406 are installed on the opposite sides of the two positioning sliders 405. The fourth transmission box 401 and the second transmission box 215 are both cooperatively provided with through chutes 409. The positioning slider 405 is slidably connected to the fourth transmission box 401, and the transmission slider 406 is slidably connected to the through chute 409. Positioning side plates 407 are installed on the opposite sides of the two transmission sliders 406. A number of support cross plates 408 are installed between the two positioning side plates 407, which are arranged in parallel and equidistantly distributed. A number of second gears 217 and third gears 218 are provided and correspond one by one. The second gears 217 and the third gears 218 are both rotatably connected to the support cross plates 408. The second gears 217 are all keyed and movably sleeved on the keyed transmission shaft 216 and are coaxial. The diameters of the second gears 217 decrease sequentially from bottom to top, and the diameters of the third gears 218 increase sequentially from bottom to top. And the contact points of the third gears 218 close to the first gear 214 are located on the same vertical line. The third screw rod 403 and the fourth rotating shaft 402 are driven by meshing through a fifth bevel gear 410. During the operation of this embodiment, multiple sets of second gears 217 and third gears 218 are provided to form gear sets with multiple transmission ratios, so as to adapt to the ointment delivery amounts of various thicknesses. By rotating the fourth rotating shaft 402 through the adjusting knob 404, and synchronously rotating the two third screws 403 through the fifth bevel gear 410, the lifting positioning slider 405 and the transmission slider 406 are moved simultaneously, so as to keep the second gear 217 and the third gear 218 horizontal, and enable stable transmission between each third gear 218 and the first gear 214.

[0025] When the present invention is in use, the staff quickly inputs the anesthetic ointment into the medicine storage barrel 101 through the feed pipe head 107, without the need to reverse the operation of the device or disassemble the components, which saves time and effort. The anesthetic ointment is guided by the support ring plate 102 and through the cooperation of the first side plate 103 and the bent guide plate 104, so that the anesthetic ointment finally forms a ribbon-like trajectory with a fixed width for extension, so as to facilitate the doctor to fully and accurately cover the application site. By rotating the limiting guide plate 105 to adjust the distance between its side and the end edge of the bent guide plate 104, and through the threaded socket of the first sleeve 111 and the first screw 108, the distance between the side of the limiting guide plate 105 and the bent guide plate 104 is accurately adjusted, so as to accurately adjust the thickness of the output ointment, so as to apply the anesthetic ointment on the affected area at one time, avoiding the pollution of the device or the affected area caused by reciprocating movement, and at the same time facilitating the application of a fixed-thickness anesthetic ointment or other ointments on a large-scale affected area, ensuring that the ointments take effect simultaneously, avoiding the invalidation of some areas due to reasons such as too fast drying, and maintaining the coating efficiency and the synchronization rate of taking effect during large-scale coating; During operation, the driving roller 222 rolls on the patient's skin, and is driven through the second rotating shaft 223, the third rotating shaft 224 and the fourth bevel gear 225, so as to drive the bonding drive shaft 216 to rotate. Subsequently, the second gear 217, the third gear 218, the first gear 214, the third bevel gear 213, the second bevel gear 211, the first rotating shaft 209, the first bevel gear 210 and the transmission gear ring 206 are driven in sequence, so that the rate of the up-and-down movement of the piston plate 106 corresponds to the rotation of the driving roller 222 through continuous transmission, so that the driving roller 222 is only used to contact the patient's skin surface for self-driving by reaction force, avoiding the problem that the ointment is over-lubricated and cannot roll during synchronous ointment coating. At the same time, it can not only flexibly adjust the thickness of the output ointment, but also avoid the disconnection of the ointment output, ensuring the continuous output of a fixed amount, fixed thickness and fixed width of ointment, so as to obtain the best delivery effect of the externally applied anesthetic ointment; During operation, due to the cross-sectional shapes of the transmission insert rod 302 and the positioning insert rod 303, they can only slide by themselves and cannot rotate relative to the second screw rod 202. At the same time, through the engagement and separation of the transmission insert rod 302 and the positioning insert groove 301, the second screw rod 202 and the support slider 201 are locked or rotated. This can not only enable the second sleeve 204 to stably push the second screw rod 202 to move up and down when being forced to rotate, but also enable the second screw rod 202 itself to rotate and lift quickly under the rotation of the user. Without a series of reverse transmission operations such as reverse rotation of the transmission drum 222, the piston plate 106 can be moved upward, quickly preparing for re-filling the ointment. The whole process does not require disassembly and installation, nor long preparations, improving the overall work efficiency. Multiple transmission ratios are formed by multiple groups of the second gear 217 and the third gear 218, enabling the transmission drum 222 to drive the second sleeve 204 to rotate more turns at the same rotational speed, so as to move the piston plate 106 downward at a faster speed, meeting the demand for a large conveying volume of special ointments and ensuring the continuous connection of the ointment under the requirements of different thicknesses and different conveying volumes.
