Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and particularly to a drug application device for acne scars. Background Art

[0002] Acne is a chronic inflammatory skin disease of the hair follicle sebaceous gland unit. If not treated early, timely, appropriately, and effectively, acne scars are likely to occur. Acne scars are often polymorphic, and the treatment is extremely challenging, involving a variety of treatment methods, and drug treatment is an important part of them. In the process of drug treatment, a suitable drug application device is of great significance;

[0003] For acne atrophic scars that are ineffective or stubborn in conventional treatment, autologous platelet-rich plasma (PRP) has gradually become a very effective treatment method. It can be used alone or in combination with microneedles or fractional laser. The combined use can not only improve the clinical efficacy, but also shorten the treatment period and reduce adverse reactions. PRP is a derivative of autologous blood, composed of a high concentration of platelets, and its platelet concentration is about 3 - 6.4 times that of untreated plasma. Platelets can induce the synthesis of a variety of growth factors that promote tissue regeneration and play a key role in tissue repair. Currently, it has been used to treat fasciitis, osteoarthritis, vitiligo, androgenetic alopecia, and can also be used for scar remodeling in plastic surgery and dermatology, as well as facial rejuvenation. PRP is a liquid substance, presenting a light yellow liquid state with moderate viscosity.

[0004] The combined use of PRP and fractional laser in the treatment of acne scars is widely used in clinical practice. Currently, in the specific implementation process, there are the following two methods for applying PRP to scars. One is to soak a facial mask dressing into a sterile container containing PRP, fully soak it, and then apply it to the wound surface of the patient after fractional laser. Although this method is convenient, concise, time-saving, and the absorption is relatively uniform, it requires a large amount of PRP extraction, and it is easy to cause some PRP to be lost and wasted. The PRP extraction process is complex, and the single extraction amount is limited. If the area of the patient's acne scar area is large, the single extraction amount used for external application by this method may not meet the single usage amount. The second method is to apply PRP on the face with a cotton swab, but this method may cause some PRP liquid to be absorbed and adhered by the cotton swab itself, and the specific amount applied to the facial scar will be reduced, thereby reducing the utilization rate of PRP and affecting the subsequent curative effect. At the same time, it also increases the work intensity of medical staff and reduces the work efficiency of medical staff.

[0005] Moreover, during the process of applying PRP, because the positions of the heating layer and the massage head for accelerating the absorption of PRP subsequently cannot be adjusted according to the size and shape of the patient's scars, the absorption of PRP by the scars is affected.

[0006] Therefore, it is necessary to provide a drug application device for acne scars for use. Summary of the Invention

The movement of the position of the moving frame will drive the position of the moving disc to move, thereby driving the positions of the heating layer and the massage head to move, and adjusting the positions of the heating layer and the driven massage head to a position suitable for the scar; adjusting the position of the heating layer can accurately treat, improve the comfort and cooperation of the patient during the treatment process; adjusting to the position where the patient feels the most comfortable, avoiding pain or discomfort caused by local overheating, so as to adapt to different body positions and avoid local overheating damage. Adjusting the position of the massage head can accurately control the amount of drug applied, adjust the massage intensity, and adapt to the scar shape.

[0021] Second, after the present invention applies PRP to the scar and heats and dries it, the heating layer works to generate heat to dry the PRP. When drying the applied PRP, the rotating motor works to drive the rotating gear to rotate on the inner ring gear, thereby driving the four heating layers to rotate, which can make the drug drying uniform, improve the drying efficiency, and promote the absorption of the drug.

[0022] Third, when the present invention massages the scar, the driving motor works to drive the inclined plate to rotate. The rotation of the inclined plate will drive the connecting rod to rotate, thereby driving the rotating ball to swing on the mounting rack. The swing of the rotating ball will drive the driving disc to swing left and right, so as to move the positions of several massage rods downward at intervals reciprocally to massage the scar, which can promote drug absorption, improve local drug blood circulation, and relieve skin tension.

Detailed implementation mode

[0041] To make the objectives, technical solutions and advantages of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with specific embodiments of the present invention and the corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0042] The following will, with reference to the drawings, detail the technical solutions provided by the embodiments of the present invention.

[0043] An embodiment of the present invention provides a drug coating device for acne scars, including a coating round seat 1, a cylinder 2 and an operating handle 3. The cylinder 2 is connected to the coating round seat 1, and the operating handle 3 is connected to the top of the cylinder 2. A PRP coating and medicine outlet assembly 4, a coating and uniform moving assembly 5 and a coating auxiliary assembly 6 are provided between the coating round seat 1 and the cylinder 2. The medicine outlet end of the PRP coating and medicine outlet assembly 4 is located on the coating round seat 1. The coating and uniform moving assembly 5 is rotatably connected to the coating round seat 1. The coating auxiliary assembly 6 is located inside the cylinder 2, and the coating auxiliary assembly 6 is slidably matched with the cylinder 2.

[0044] It should be noted that a rechargeable lithium battery is provided inside the cylinder 2 to supply power for subsequent coating work.

[0045] Specifically, an outer circular groove 11 and an inner circular groove 12 are provided at the bottom of the smearing circular seat 1. A heating through groove 13 is provided between the outer circular groove 11 and the inner circular groove 12. A medicine outlet hole 14 is provided beside the middle position of the smearing circular seat 1. The medicine outlet hole 14 is an inner inverted V-shaped hole. A number of massage moving holes 15 are provided on the smearing circular seat 1.

[0046] Specifically, the PRP smearing medicine outlet assembly 4 includes a smearing inner ball 40, a circular tube 41, a moving rod 42, a medicine containing cylinder 43, a transfer cylinder 44, a reset structure 45 and a moving ball 46. The smearing inner ball 40 is rotatably connected in the medicine outlet hole 14 and the smearing inner ball 40 can move up and down in the medicine outlet hole 14. The circular tube 41 is vertically arranged on the smearing circular seat 1. The moving rod 42 is slidably connected in the smearing circular seat 1 through the reset structure 45. The smearing inner ball 40 can move in the circular tube 41. The bottom of the moving rod 42 abuts against the smearing inner ball 40. The medicine containing cylinder 43 is connected to the top of the circular tube 41. The transfer cylinder 44 is located at the bottom of the medicine containing cylinder 43. A medicine discharging hole 47 and a medicine inlet hole are respectively provided at the bottom and the top of the medicine containing cylinder 43. The moving rod 42 is slidably connected to the transfer cylinder 44. The moving ball 46 is located at the top of the moving rod 42. The moving ball 46 moves in the medicine discharging hole 47. The medicine discharging hole 47 is an inner inverted V-shaped hole. Two medicine outlet pipes 48 are provided on the transfer cylinder 44. The two medicine outlet pipes 48 extend above the medicine outlet hole 14. A sealing plug 49 for blocking the medicine inlet hole is provided on the cylinder 2.

[0047] Opening the sealing plug 49 can place the PRP into the medicine containing cylinder 43, and then the sealing plug 49 is inserted into the medicine inlet hole to seal the medicine containing hole.

[0048] It should be noted that PRP is a liquid substance, which itself presents a light yellow liquid state. PRP has fluidity. After the moving ball 46 is pushed upward from the medicine discharging hole 47, it can flow downward from the medicine discharging hole 47 into the transfer cylinder 44, and then the PRP is moved to the medicine outlet hole 14 through the two medicine outlet pipes 48, and the PRP is smeared on the scar through the medicine outlet hole 14.

[0049] Specifically, the reset structure 45 includes mounting plates 451 symmetrically arranged inside the circular tube 41. A reset spring 452 is provided on the mounting plate 451. A reset plate 453 is provided on the reset spring 452. The reset plate 453 is connected to the outer side wall of the moving rod 42. The reset plate 453 is slidably connected to the inner side wall of the circular tube 41.

[0050] After the application inner ball 40 comes into contact with the scar, the application inner ball 40 will move upward within the medicine outlet hole 14, thereby driving the moving rod 42 to slide within the circular tube 41 through the two reset plates 453. When the moving rod 42 moves upward, it will drive the position of the moving ball 46 to move upward from the medicine discharging hole 47, opening the medicine discharging hole 47. Then, PRP flows downward from the medicine discharging hole 47 into the transfer cylinder 44 and flows out through the two medicine outlet pipes 48 to the medicine outlet hole 14, and is applied to the scar.

[0051] While the moving rod 42 is moving upward, it will drive the two reset springs 452 to move respectively on the two mounting plates 451, stretching the reset springs 452.

[0052] After the application of PRP to the scar is completed, the reset springs 452 need to be reset. The reset springs 452 in the stretched state return to the original state. At this time, the position of the moving rod 42 can be pulled downward. When the moving rod 42 moves downward, it will drive the moving ball 46 to return to the medicine discharging hole 47, blocking the medicine discharging hole 47 so that PRP no longer flows downward. At this time, the inner application sphere 52, the outer application sphere 51, and the application inner ball 40 can be cleaned to facilitate the next application of PRP to the scar.

[0053] Specifically, the uniform application moving assembly 5 includes a plurality of outer application spheres 51 arranged at equal intervals in the outer circular groove 11 and a plurality of inner application spheres 52 arranged at equal intervals in the inner circular groove 12. The outer application spheres 51 rotate within the outer circular groove 11, and the inner application spheres 52 rotate within the inner circular groove 12.

[0054] After applying PRP to the scar, by moving the operation handle 3, the outer application spheres can be driven to rotate within the outer circular groove 11 respectively, and the inner application spheres can be driven to rotate within the inner circular groove 12, so as to apply PRP evenly to the scar, enabling the drug to be absorbed by the scar to the greatest extent and increasing the activity of drug application.

[0055] It should be noted that when the application device is in a vertical state, the bottom of the application inner ball 40 is located below the inner application sphere 52 and the outer application sphere 51. When the application inner ball 40 moves upward to be flush with the inner application sphere 52 and the outer application sphere 51, it just makes the moving ball 46 move upward from the medicine discharging hole 47 to discharge PRP outward.

[0056] Specifically, the application assisting assembly 6 includes an assisting moving structure 61, an application heating structure 62, and an application massaging structure 63. The assisting moving structure 61 is arranged within the cylinder 2, the application heating structure 62 is located on the assisting moving structure 61 and at the heating through groove 13, and the application massaging structure 63 is located at the middle position of the application round seat 1.

[0057] Specifically, the auxiliary moving structure 61 includes a moving frame 611, a moving disc 612, a moving gear 613, a moving rack 614, a rotating button 615 and a moving fixed seat 616. The moving fixed seat 616 is provided with a plurality of moving fixed seats 616, and the plurality of moving fixed seats 616 are symmetrically arranged at equal intervals inside the cylinder 2. The moving frame 611 is slidably connected to the plurality of moving fixed seats 616. The moving rack 614 is located on the moving frame 611. The moving disc 612 is connected to the top of the moving frame 611. The moving disc 612 is slidably matched with the cylinder 2. A rotating groove 21 is provided on the cylinder 2. The rotating button 615 is rotatably connected in the rotating groove 21 of the cylinder 2. The moving gear 613 and the rotating button 615 are coaxially connected, and the moving gear 613 and the moving rack 614 are meshed.

[0058] Specifically, the cylinder 2 is provided with a placement cavity 22 on the side wall of the rotating groove 21, two fixing blocks 23 are provided in the placement cavity 22, a sliding pin 24 for sliding fit is provided between the two fixing blocks 23, and a plurality of equally spaced sockets 617 are provided on the side wall of the rotating knob 615.

[0059] When the position of the heating layer 624 and the massage head 638 is subsequently adjusted according to the size and shape of the scar, the sliding pin 24 is pulled out from the insertion hole 617, and then the rotating knob 615 is turned to drive the moving gear 613 to rotate on the moving rack 614, thereby driving the moving frame 611 to move on the plurality of moving fixed seats 616, and the movement of the position of the moving frame 611 will drive the position of the moving disc 612 to move, thereby driving the position of the heating layer 624 and the massage head 638 to move, and the position of the heating layer 624 and the massage head 638 is adjusted to a suitable position for the scar;

[0060] When applying acne scar medication, the adjustable position of the heating layer 624 has the following benefits:

[0061] Precision treatment: The distribution of acne scars is often irregular, and the scar locations, sizes, and shapes vary from patient to patient. The adjustable position of the heating layer 624 allows it to be precisely aligned with the scar, ensuring that the heat is concentrated on the area that needs treatment, avoiding heat waste on normal skin, improving the treatment effect while reducing the impact on surrounding normal tissues. For example, for a dot scar on the cheek, the heating layer 624 can be precisely adjusted to the scar for targeted heating.

[0062] Improve comfort: Everyone has different sensitivities and tolerances to heat. By adjusting the position of the heating layer 624, according to the specific feelings of the patient, the heating layer 624 can be adjusted to the position where the patient feels most comfortable, avoiding pain or discomfort caused by local overheating, thus improving the comfort and cooperation of the patient during the treatment process.

[0063] Adapt to different body positions: During the drug application process, the patient may be in different body positions, such as sitting, lying down, etc. The adjustable heating layer 624 can make corresponding adjustments according to the changes in the patient's body position, always maintaining effective heating of the scar area. For example, when the patient is lying down applying the drug, the heating layer 624 can be adjusted to a suitable angle and position to ensure that even when the body position changes, the heat can be evenly transmitted to the scar.

[0064] Avoid local overheating damage: If the position of the heating layer 624 is fixed, it may cause the local temperature to be too high due to long-term heating in the same area, increasing the risk of skin burns. The adjustable heating layer 624 can change the heating point regularly, making the heat more evenly distributed on the scar surface, avoiding local overheating, reducing the possibility of skin damage, and ensuring the safety of the treatment.

[0065] When applying drugs to acne scars, adjusting the distance between the massage head 638 and the scar has the following benefits:

[0066] Control the amount of drug applied: The distance between the massage head 638 and the scar affects the amount of drug applied. When the distance is relatively close, the massage head 638 will carry more drugs during movement and directly act on the scar surface, which is suitable for use in areas with more severe scars that require more drug coverage to ensure sufficient drug dosage to play a therapeutic role. For cases where the scars are milder or the area is larger and more uniform drug dispersion is needed, appropriately increasing the distance between the massage head 638 and the scar can make the drug more evenly dispersed on the skin surface during application, avoiding waste or adverse reactions caused by excessive local drugs.

[0067] Adjust the massage intensity: Different distances can produce different massage intensities. When the distance is relatively small, the pressure of the massage head 638 on the scar is relatively large. This relatively large pressure can promote better penetration of the drug into the deep layer of the skin, and at the same time play a certain massage and stimulation role on the scar tissue, helping to promote local blood circulation, enhance tissue metabolism, and improve the texture and appearance of the scar. When the scar is in the initial stage of recovery or the skin is more sensitive, appropriately increasing the distance between the massage head 638 and the scar can reduce the massage intensity, avoid over-stimulating the fragile skin, prevent discomfort reactions such as pain and redness and swelling, and is beneficial to protecting the skin barrier function and creating a stable environment for scar repair.

[0068] Adapting to Scar Morphology: The morphology and surface flatness of acne scars vary. Adjusting the distance between the massage head 638 and the scar can better accommodate these differences. For depressed scars, the massage head 638 can be appropriately close to the bottom of the scar to apply the drug more precisely to the depressed area. At the same time, using the pressure of the massage head 638 to gently fill and massage the depression can promote collagen production and improve the degree of depression. For hypertrophic scars, the massage head 638 should maintain an appropriate distance from the scar surface, which can not only evenly apply the drug but also avoid over-stimulating the proliferated tissue and prevent further scar proliferation. In addition, for irregularly shaped scars, by flexibly adjusting the distance between the massage head 638 and different parts of the scar, it can ensure that the massage head 638 always maintains proper contact with the scar surface, making the drug application and massage effects more uniform and comprehensive.

[0069] Specifically, the coating and heating structure 62 includes a rotating motor 621, a rotating gear 622, a rotating ring 623, and four heating layers 624. The rotating motor 621 is located on the moving disc 612. The rotating ring 623 is rotatably connected to the bottom of the moving disc 612. The rotating gear 622 is located on the main shaft of the rotating motor 621. The rotating ring 623 is provided with an inner ring gear 625 meshing with the rotating gear 622. The four heating layers 624 are arranged at equal intervals at the bottom of the rotating ring 623, and the heating layers 624 correspond to the heating through grooves 13.

[0070] After applying PRP to the scar and heating and drying it, the heating layer 624 generates heat to dry the PRP. When drying the applied PRP, the rotating motor 621 operates to drive the rotating gear 622 to rotate on the inner ring gear 625, thereby driving the four heating layers 624 to rotate.

[0071] Uniform Drying: The rotation of the heating layer 624 enables the drug to be evenly heated on the scar surface, avoiding local overheating or overcooling. Since the heating layer 624 rotates around the scar area, the drug at all angles can be dried to the same extent, which helps to improve the consistency and effect of drug drying and enables the drug to play a better role.

[0072] Improving Efficiency: The four heating layers 624 rotate simultaneously, expanding the drying coverage area and enabling the drug drying process to be completed in a shorter time. Compared with drying by a single fixed-position heat source, this method can dry multiple parts simultaneously, reducing the drying time and improving the overall efficiency, especially suitable for scars with a large area or situations where the drug needs to be quickly dried.

[0073] Promote drug absorption: The heat generated by the rotating heating layer 624 is evenly distributed and continuously stable, which can promote local blood circulation of the scar, facilitate better penetration of the drug into the skin tissue, and improve the drug absorption effect. At the same time, the uniform heat can also enable the active ingredients in the drug to play a better role and enhance the repair effect on the scar.

[0074] The heating layer 624 consists of the following components:

[0075] Heating element: This is the core component of the heating layer 624. Commonly used ones include resistance wires, heating sheets, electrothermal films, etc. By passing an electric current through these components, heat is generated to achieve heating of the scar area. For example, some heating patches use resistance wires, which can convert electrical energy into heat energy and apply hot compress to the scar at a constant temperature.

[0076] Temperature control element: To ensure the safety and effectiveness of heating and prevent damage to the skin caused by excessive temperature, the heating layer 624 usually has a temperature control element. Commonly used ones include thermistors, temperature sensors, etc. They can monitor the temperature of the heating layer 624 in real time and transmit the signal to the control circuit. When the temperature reaches the set upper limit, the control circuit will automatically cut off the power supply or reduce the heating power to keep the temperature within a safe range.

[0077] Heat insulation material: To reduce heat dissipation to the surrounding environment, improve heating efficiency, and avoid scalding the surrounding skin, the heating layer 624 uses heat insulation materials. Commonly used heat insulation materials include ceramic fibers, aerogels, foam plastics, etc. These materials have low thermal conductivity and can effectively concentrate the heat on the scar area, reducing heat waste.

[0078] Power supply module: It provides electrical energy for the heating element. Commonly used ones include batteries, power adapters, etc. If it is a wearable heating device, usually a small lithium battery is used, which is convenient to carry and use; while for some fixed heating devices, a power adapter may be used to supply power through the mains to ensure stable power supply.

[0079] Protective layer: It is used to protect the various components inside the heating layer 624, preventing them from being interfered with and damaged by external factors. At the same time, the protective layer can also make the heating layer 624 more comfortable to contact with the skin. Usually, soft and breathable materials such as silicone and polyester fiber are used. Some protective layers also have waterproof functions so that they can be used normally in some special situations.

[0080] Specifically, the smearing and massaging structure 63 includes a mounting frame 631, a rotating ball 632, a driving disk 633, a driving motor 634, an inclined plate 635 and a connecting rod 636. The mounting frame 631 is connected to the moving disk 612. The driving motor 634 is located at the bottom of the mounting frame 631. The inclined plate 635 is connected to the main shaft of the driving motor 634. The driving disk 633 is rotatably connected to the mounting frame 631 through the rotating ball 632. The connecting rod 636 is connected to the rotating ball 632 and the inclined plate 635. A plurality of massaging rods 637 which are slidably matched are arranged on the mounting frame 631. A massage head 638 is arranged at the bottom of the massaging rod 637. The top of the massaging rod 637 is in contact with the driving disk 633. A connecting spring 639 is arranged between the massaging rod 637 and the mounting frame 631. The massaging rod 637 slides in the massage moving hole 15.

[0081] It should be noted that the driving disk 633 is in an inclined state. When massaging, the auxiliary moving structure 61 will drive the massaging rod 637 to move downward in the massage moving hole 15, move the position of the massage head 638 above the scar, and perform massage work on the scar.

[0082] When massaging the scar, the driving motor 634 works to drive the inclined plate 635 to rotate. The rotation of the inclined plate 635 will drive the connecting rod 636 to rotate, thereby driving the rotating ball 632 to swing on the mounting frame 631. The swing of the rotating ball 632 will drive the driving disk 633 to swing left and right, so as to reciprocally move the positions of a plurality of massaging rods 637 downward at intervals to perform massage work on the scar. After the position of the massaging rod 637 moves downward, the connecting spring 639 will be compressed. Then, through the reset of the connecting spring 639, the position of the massaging rod 637 will be reset upward on the mounting frame 631 to facilitate the next massage work on the scar, so that PRP can be absorbed by the scar to the greatest extent and the smearing activity can be increased.

[0083] Massaging the scar has the following benefits:

[0084] Promote drug absorption: Massage can dilate the pores on the skin surface, accelerate the penetration of drugs into the deep layer of the skin. At the same time, massage can promote local blood circulation, enable drugs to be delivered to the scar tissue faster, improve the utilization rate of drugs, and enhance the treatment effect.

[0085] Improve local blood circulation: Massage helps to accelerate blood circulation, bring more oxygen and nutrients to the scar tissue, promote cell metabolism, accelerate tissue repair and regeneration, is beneficial to reducing the pigmentation of the scar, and making the scar gradually soften and flatten.

[0086] Relieve skin tension: Acne scars may cause a feeling of tightness and discomfort in the skin. Massage can relax the skin muscles, relieve this tension, make the patient feel comfortable, and at the same time help reduce the discomfort and itching caused by skin tension.

[0087] The above are only embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, various changes and modifications can be made to the present invention. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included within the scope of the claims of the present invention.
