The phrase "in one embodiment" appearing in various places throughout this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.
[0033] Example 1
[0034] Reference Figures 1-9 As shown in the figure, it is the first embodiment of the present application, which provides a directional Chinese medicine transdermal drug delivery device, comprising:
[0035] The base 100 is disposed on a plane.
[0036] The rotating arm group 200 is fixed to a plane through the base 100. The rotating arm group 200 includes a first support arm 210, a second horizontal arm 220 and a third rotating arm 230. The first support arm 210 and the second horizontal arm 220, and the second horizontal arm 220 and the third rotating arm 230 are rotatably connected.
[0037] The upper and lower telescopic parts 300 fix the ends of the rotating arm group 200, and realize horizontal rotation through the rotating arm group 200. The upper and lower telescopic parts 300 include a cylinder 1 310 and an actuator plate 320. The cylinder 1 310 is assembled at one end of the third rotating arm 230 away from the second horizontal arm 220, and the actuator plate 320 is fixed to the bottom of the cylinder 1 310.
[0038] like Figure 2-Figure 3 As shown, the clamping member 400 is hoisted on the upper and lower telescopic members 300, and the clamping range of the clamping member 400 is adjusted by the telescopic movement of the upper and lower telescopic members 300;
[0039] The clamping component 400 includes a suspension plate 410, a clamping assembly 420, and a drive assembly 430. The drive assembly 430 includes a second cylinder 431, a drive ring 432, and a first positioning plate 433. The second cylinder 431 is fixed to the surface of the suspension plate 410 via the first positioning plate 433. The drive ring 432 is fixed to the surface of the output end of the second cylinder 431. The output end of the second cylinder 431 drives the drive ring 432 to reciprocate up and down.
[0040] The clamping assembly 420 includes a positioning plate 2 421, an inner connecting tube 422 and an outer pressing tube 423. A driving ring 432 is arranged at the top end of the outer pressing tube 423. A linkage rod 424 is arranged between the outer pressing tube 423 and the driving ring 432. The driving ring 432 that reciprocates up and down drives the outer pressing tube 423 to reciprocate up and down synchronously through the linkage rod 424; the inner connecting tube 422 is fixed to the suspension plate 410 through the positioning plate 2 421. A plurality of equally spaced annular mounting grooves are provided on the surface of the inner connecting tube 422. A grabbing clamp 425 is installed in the mounting groove. The plurality of grabbing clamps 425 are based on the central axis of the inner connecting tube 422 and are synchronously expanded or contracted at equal intervals and angles along the radial direction to achieve grabbing.
[0041] The transdermal drug delivery component 500 is clamped by the clamping component 400 and pressed against the patient's back. The transdermal drug delivery component 500 includes a drug delivery component 510 and an application component 520. The drug delivery component 510 presses and delivers the drug to the application component 520. The application component 520 includes a middle plate 522 and a plurality of pyramid-shaped silicone micro-protrusions 521 arranged in an array on the surface of the middle plate 522. The upper and lower telescopic components 300 extend and retract to transmit force to the drug delivery component 510 so that the silicone micro-protrusions 521 are compressed and closely adhered to the surface of the skin, so that the lipids in the stratum corneum of the surface of the skin are loosened to form "honeycomb-like" channels. Since the pyramid-shaped tips of the silicone micro-protrusions 521 preferentially contact the surface of the skin, the silicone micro-protrusions 521 are in contact with the surface of the skin. The pressure along the slope of 21 decreases gradually, forming a pore size gradient, so as to form a nano-scale lipid gap network concave texture on the surface of the skin, forming micron-scale pores of different pore sizes, so as to allow nano-scale drug molecules of different molecular weights to penetrate. The silicone micro-protrusions 521 have greatly improved the drug introduction efficiency compared with plaster dressings. Compared with the micron-scale penetrating micropores formed by microneedle puncture, which directly destroy the skin barrier structure, the present application uses the silicone micro-protrusions 521 to apply pressure to temporarily loosen the lipid bilayer of the stratum corneum, forming a natural lipid gap network mechanical stress loosened lipid layer, which is non-invasive and painless, greatly improving the drug transdermal efficiency while completely avoiding the pain and infection risks of traditional puncture technology.
[0042] This application uses the mechanical stress of the silicone micro-protrusions 521 to reversibly loosen the lipid bilayer of the stratum corneum without destroying the integrity of the skin, forming nano-scale penetration channels that are suitable for different molecular weights. Compared with microneedle puncture technology, it achieves non-invasive, painless, and high-precision compound delivery.
[0043] like Figure 7 As shown, the silicone micro-protrusion 521 includes an outer shell 5211 and an inner shell 5212. A drug delivery channel is formed between the outer shell 5211 and the inner shell 5212. Connecting blocks 5213 are provided at the four corners of the outer shell 5211 and the inner shell 5212. The outer shell 5211 and the inner shell 5212 are connected by the connecting blocks 5213. The inner shell 5212 and the connecting blocks 5213 reduce the inner cavity capacity of the outer shell 5211 to reduce the storage amount of the drug in the inner cavity of the outer shell 5211.
[0044] Micro-bumps 5214 are provided on the four sides of the outer shell layer 5211. The tip of the outer shell layer 5211 and the micro-bumps 5214 on the side of the outer shell layer 5211 are coated with keratin softening enzyme to release and degrade keratin under pressure to further expand the pores. The multiple micro-bumps 5214 on the side of the outer shell layer 5211 realize multiple stress points, effectively forming multiple effective stress points on the surface of the skin, compressing the surface of the skin to form pores for the directional introduction of drugs.
[0045] like Figure 4 and Figure 5 As shown, the drug delivery component 510 includes a drug delivery cylinder 511, a partition plate 512, and an outer keeper plate 513. The drug delivery cylinder 511 includes a conical upper cylinder 5111 and a circular lower cylinder 5112 connected as an integral body. The outer keeper plate 513 is mounted on the bottom end of the circular lower cylinder 5112. A plurality of guide holes 5113 are formed on the surface of the circular lower cylinder 5112. The partition plate 512 is disposed in the inner cavity of the drug delivery cylinder 511 and is guided by the conical upper cylinder 5111. It moves along the axis of the conical upper cylinder 5111 and moves toward the circular lower cylinder 5112 to squeeze the drug solution into the guide holes 5113.
[0046] The conical upper cylinder 5111 is divided into an air cavity and a liquid medicine cavity by a partition plate 512. The partition plate 512 pushes the liquid medicine in the liquid medicine cavity into the guide hole 5113.
[0047] The drug delivery component 510 further includes an air pump 514 and an air tube 515. The air tube 515 is connected to the air outlet end of the air pump 514 and its other end is connected to the end of the conical upper cylinder 5111 facing away from the circular lower cylinder 5112. The air pump 514 increases the air volume in the air cavity to push the partition plate 512 toward the circular lower cylinder 5112 to deliver the drug solution.
[0048] A plurality of clamps 516 are fixed to the outer surface of the dosing barrel 511 , and the air pump 514 is assembled to the outer surface of the dosing barrel 511 through the clamps 516 .
[0049] like Figure 2 、 Figure 4-Figure 6 、 Figure 8-Figure 9 As shown, the transdermal drug dispensing component 500 also includes a pressure-dividing sealing component 530 and a heat-releasing component 540. The pressure-dividing sealing component 530 includes a first pressure-dividing member 531 and a second pressure-dividing member 532. The first pressure-dividing member 531 and the second pressure-dividing member 532 are respectively arranged on both sides of the middle plate 522. The first pressure-dividing member 531 is used to seal the gap between the middle plate 522 and the surface layer of the skin, and the second pressure-dividing member 532 is used to seal the gap between the middle plate 522 and the outer armature plate 513. The surface of the middle plate 522 is provided with a plurality of rectangular through grooves 5221 distributed in an array, and the plurality of rectangular through grooves 5221 correspond to the plurality of silicone micro-protrusions 521.
[0050] like Figure 5 and Figure 6 A filter membrane 5222 and a drug-loaded membrane 5223 are provided at each rectangular groove 5221 of the middle plate 522, wherein the drug-loaded membrane 5223 is provided on the side of the rectangular groove 5221 close to the silicone micro-protrusion 521; the filter membrane 5222 and the drug-loaded membrane 5223 are both designed with a multi-layer structure, and the surface of the filter membrane 5222 is provided with nano-pores of different pore sizes for intercepting ineffective macromolecules in the drug; the drug-loaded membrane 5223 is made of different materials to improve the transmittance of different components of the drug.
[0051] Specifically, the filter membrane 5222 is composed of a surface membrane, a middle membrane and a bottom membrane from top to bottom. The nanopores on the surface of the surface membrane have a pore size of 50nm, the nanopores on the surface of the middle membrane have a pore size of 20nm, and the nanopores on the surface of the bottom membrane have a pore size of 2nm. Through the coordinated filtration of the surface membrane, the middle membrane and the bottom membrane, the precipitation and stratification of components are eliminated, and the efficacy of the original prescription is retained; the drug-loaded membrane 5223 is divided into a hydrophilic layer, an amphiphilic layer and a hydrophobic layer from top to bottom. The hydrophilic layer loads polar components such as alkaloids, Polysaccharides, including sodium alginate hydrogel, are preferentially released through capillary action. The amphiphilic layer is loaded with moderately polar components such as flavonoid glycosides. A chitosan-lipid composite membrane is used to control the release by utilizing the osmotic pressure difference. The hydrophobic layer is loaded with non-polar components such as volatile oils, which diffuse through a microporous silica carrier relying on a concentration gradient. The filter membrane 5222 and the drug-loaded membrane 5223 are used to solve the three-level synergy of "physical screening-chemical controlled release-bioadaptation", breaking through the problems of component interference and low efficiency in the transdermal delivery of compound Chinese medicines.
[0052] like Figure 8-Figure 9 As shown, the first pressure-dividing member 531 includes a lower silicone strip 5311 and a vacuum adsorption strip 5312 connected to the surface of the lower silicone strip 5311. The lower silicone strip 5311 forms a frame strip structure to enclose the lower surface of the middle plate 522. The second pressure-dividing member 532 includes an upper silicone strip 5321 and a frame strip plate 5322 connected to the surface of the upper silicone strip 5321. The frame strip plate 5322 is connected to the outer armature plate 513 through the upper silicone strip 5321.
[0053] like Figure 8-Figure 9 As shown, the surface of the outer mortise plate 513 is connected to a telescopic frame strip pressure plate 533, and the telescopic frame strip pressure plate 533 includes an upper frame pressure strip 5331 and a lower frame pressure strip 5332, wherein the upper frame pressure strip 5331 is engaged and moved in the inner cavity of the lower frame pressure strip 5332 to adjust the length of the telescopic frame strip pressure plate 533, and the bottom of the outer mortise plate 513 and the round cake lower cylinder 5112 are provided with a plurality of telescopic pressure rods 534, and the telescopic pressure rods 534 and the telescopic frame strip pressure plate 533 are synchronously retracted, and the minimum height to which the telescopic pressure rods 534 and the telescopic frame strip pressure plate 533 can be retracted is the superimposed height of the upper silicone strip 5321 and the frame strip plate 5322;
[0054] Among them, the upper frame pressure strip 5331 is fixed to the surface of the outer frame plate 513, the lower frame pressure strip 5332 is fixed to the surface of the middle plate 522, one end of the telescopic pressure rod 534 is fixed to the middle plate 522, and the other end is fixed to the outer frame plate 513 or the round lower tube 5112. There are multiple telescopic pressure rods 534, which are arrayed on the middle plate 522 and avoid the position of the rectangular through groove 5221.
[0055] Example 2
[0056] Reference Figure 8-Figure 9 , which is the second embodiment of the present application, is based on the previous embodiment, except that the heat-releasing assembly 540 includes two rectangular plates 541 and a connecting rod 542 , and the two rectangular plates 541 are connected by the connecting rod 542 .
[0057] Among them, L-shaped grooves are opened at the relative positions of the outer armature plate 513 and the middle plate 522. Two rectangular plates 541 are rotatably connected in the L-shaped grooves. The outer armature plate 513 is equipped with a temperature sensor 543, and the cylinder 1 310 is equipped with a controller. When the temperature sensor 543 detects that the temperature of the drug transdermal leakage site increases, the controller controls the output end of the cylinder 1 310 to move upward.
[0058] A vibrator is also fixed on the surface of the outer compression cylinder 423 .
[0059] Working principle: Manually push the second horizontal arm 220 and the third rotating arm 230 to rotate the third rotating arm 230 to the target skin area, start the cylinder 1 310 to press the clamping component 400 and the transdermal applicator 500 downward, turn on the vibrator, and transmit the vibration to the transdermal applicator 500 through the external compression cylinder 423. The downward pressing position of the clamping component 400 and the transdermal applicator 500 is specifically determined according to the patient's own feelings.
[0060] The pyramid tips of the silica microprotrusions 521 generate a certain pressure on the surface of the skin, forcing the lipid bilayer of the stratum corneum to shear slip, forming loose channels with a pore size gradient distribution, and further expanding the pore size of the channels through stratum corneum softening enzymes, thereby improving the directional transdermal efficiency of drugs.
[0061] Air pump 514 injects compressed air into the air cavity of conical upper tube 5111, pushing partition plate 512 toward circular lower tube 5112, squeezing the compound Chinese herbal extract from the liquid medicine cavity. The liquid medicine flows evenly through guide holes 5113 in circular lower tube 5112, passing through filter membrane 5222 and drug-loaded membrane 5223 in sequence, ensuring efficient and rapid drug penetration.
[0062] The telescopic frame pressure plate 533 automatically adapts to varying body surface curvatures by nesting and expanding the upper frame pressure bar 5331 and the lower frame pressure bar 5332. The telescopic pressure rod 534 works in conjunction with the frame pressure plate 533 to adjust pressure distribution in real time as the patient's position changes. This ensures consistent pressure from the multiple silicone micro-protrusions 521 squeezing the skin surface, preventing excessive pressure and creating more effective channels for improved drug delivery.
[0063] When the temperature sensor 543 detects that the temperature of the skin surface is too high, the controller controls the output end of the cylinder 310 to move upward, so that the clamping component 400 and the transdermal applicator 500 move upward, the vacuum adsorption strip 5312 is adsorbed on the skin surface, the telescopic frame bar pressure plate 533 and the telescopic pressure rod 534 are passively extended, and the upward-moving round cake lower cylinder 5112 and the outer yoke plate 513 pull the middle plate 522 through the telescopic frame bar pressure plate 533 and the telescopic pressure rod 534, so that the silicone micro-protrusion 521 reduces the pressure applied to the skin surface; secondly, the distance between the outer yoke plate 513 and the middle plate 522 increases, and the two rectangular plates 541 are respectively installed in the L-shaped grooves of the outer yoke plate 513 and the middle plate 522. The two rectangular plates 541 are flipped by the pull of the connecting rod 542, and the hot air is exchanged with the outside world through the L-shaped groove.
[0064] After the preset dosing time is complete, the edge of the vacuum strip 5312 is moved to release it from the skin's surface. The controller then controls cylinder 1 310 to drive the clamping component 400 and transdermal applicator 500 further upward to a predetermined position. Cylinder 2 431 pulls the drive ring 432 upward, which in turn drives the outer compression cylinder 423 upward via the linkage rod 424. The gripper 425 simultaneously deploys along the mounting groove of the inner connecting cylinder 422, releasing the transdermal applicator 500.
