Description

Technical Field

[0001] This invention belongs to the field of medical device technology, specifically relating to a special medicine application device for traditional Chinese medicine dermatology. Background Technology

[0002] Dermatological medication application devices are a class of medical devices or assistive tools specifically designed to help patients apply topical medications (such as ointments, creams, gels, etc.) more accurately, hygienically, and evenly. They are especially suitable for large-area skin diseases (such as eczema, psoriasis), medication on sensitive areas, or situations where direct contact with the skin needs to be avoided. Roller-on applicators are similar to rollerball perfumes, dispensing the ointment evenly by rolling the ball head. They are suitable for one-handed operation, allowing for thin and even application, and are suitable for small areas or sensitive areas.

[0003] Topical dermatological medications are an important way to treat chronic skin diseases such as eczema, psoriasis, and dermatitis. Traditional rollerball applicators are favored by some patients because they are easy to operate and avoid direct hand contact with the medication. However, the dosage control of existing medication application devices relies on manual experience and cannot be accurately adjusted according to the pressure applied, which may lead to overdosing or underdosing, affecting the efficacy and even causing side effects. When the rollerball structure is not compatible with the viscosity of the medication, it is easy to cause application gaps or local accumulation, which is especially unfavorable for covering large areas of skin. Summary of the Invention

[0004] The purpose of this invention is to provide a special medicine application device for traditional Chinese medicine dermatology, in order to solve the problems mentioned in the background art, that existing dermatology roller-type medicine applicators cannot control the amount of medicine applied according to the pressure applied, and cannot apply the medicine evenly.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A special application device for traditional Chinese medicine dermatology includes:

[0007] Medicine storage tank;

[0008] A screw-on mechanism is provided at the top of the medicine storage tank;

[0012] The coating mechanism is fixedly connected to the bottom end of the connecting mechanism.

[0013] Preferably, the fixing mechanism includes a first mounting collar, the outer side of which has a plurality of first insertion slots, a second mounting collar fixedly connected to the bottom end of the first mounting collar, a mounting plate fixedly connected to the bottom end of the second mounting collar, and a plurality of second insertion slots through the outer side of the second mounting collar.

[0014] Preferably, the top end of the compression spring is fixedly connected to the bottom end of the first mounting collar, the dispensing ball is mounted on the bottom end of the telescopic pressing column through a limiting plate, and the dispensing ball is rotatably connected to the bottom end of the telescopic pressing column.

[0015] Preferably, the telescopic pressing column is slidably connected inside the second mounting sleeve, the infiltration chamber is fixedly connected to the top of the first mounting sleeve, the inner side wall of the infiltration chamber is provided with a hole or groove of the same size as the infiltration groove and the opening position of the infiltration groove is corresponding to that of the infiltration groove, and the infiltration groove is horizontally provided in three sets at the top of the telescopic pressing column.

[0016] Preferably, the rack plate is fixedly connected to the outside of one side of the telescopic pressing column, the top end of the fixing rod is fixedly connected to the bottom end of the second mounting collar, and the top end of the sliding seat is fixedly connected to the bottom end of the mounting plate.

[0017] Preferably, the toothed rod is slidably connected to the outside of the sliding seat, the rotating gear is rotatably connected to the outside of the fixed rod, and multiple sets of the pressing mechanism and the connecting mechanism are provided inside the fixed mechanism.

[0018] Preferably, the screwing mechanism includes a bottle cap seat, a connecting cap is sleeved on the outside of the bottle cap seat, and an anti-slip groove is provided on the outside of the medicine storage tank.

[0019] Preferably, the bottle cap seat has a threaded groove on its outside, and the connecting cap is screwed onto the outside of the bottle cap seat by engaging with the threaded groove that matches the bottle cap seat. Two anti-slip grooves are symmetrically arranged on the outside of the medicine storage tank.

[0020] Preferably, the application mechanism includes a fixed plate, a telescopic spring is fixedly connected to the bottom end of the fixed plate, and an application block is fixedly connected to the bottom end of the telescopic spring.

[0021] Preferably, the fixing plate is elastically telescopically connected to the coating block via a telescopic spring, the coating block is a hemispherical hollow structure, and the fixing plate is slidably connected inside the coating block.

[0022] Compared with the prior art, the beneficial effects of the present invention are:

[0023] (1) The present invention, through the setting of telescopic pressing column, dispensing ball, rack plate and rotating gear, enables the telescopic pressing column to slide and extend inside the first mounting sleeve when the medicine storage tank is pressed, through the elastic extension and contraction of the compression spring. By the pressing pressure, the dispensing groove can be made to correspond with the hole groove on the dispensing chamber. When the pressure is shallow, only the bottom dispensing groove corresponds with the bottom hole groove of the dispensing chamber, so as to achieve slight penetration of the medicine in the medicine storage tank. When the pressing pressure on the medicine storage tank is increased, all three rows of dispensing grooves can be made to correspond with the hole groove on the dispensing groove, so as to achieve full penetration of the medicine. In addition, the amount of medicine applied can be precisely controlled by adjusting the pressing pressure. Furthermore, through the movement and rotation of the dispensing ball at the bottom of the telescopic pressing column, the medicine inside the telescopic dispensing column can be applied to the patient's skin surface, so as to achieve precise adjustment of the dispensing amount according to the pressing pressure.

[0024] (2) The present invention, through the setting of a rack plate, a rotating gear, a fixed rod and a toothed rod, enables the telescopic pressing column to move up and down when it is pressed down. Through the meshing connection between the rack plate and the rotating gear, the rotating gear can be driven to rotate. At this time, through the meshing connection between the rotating gear and the toothed rod, the application mechanism can be moved in the opposite direction, so that the application mechanism can perform abutment operation on the patient's skin. Thus, when the application device is moving and applying, the application block can rub the skin evenly, improve the uniformity of drug application, and also increase the skin temperature through the friction between the application block and the skin, thereby achieving efficient drug absorption. Moreover, the elastic extension and contraction between the application block and the telescopic spring can make the application block evenly adhere to the skin surface according to the different downward pressure of the telescopic pressing column.

[0032] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0033] Example 1:

[0034] Please see Figures 1-6 As shown, a special application device for traditional Chinese medicine dermatology includes:

[0035] Medicine storage tank 1;

[0036] A screw-on mechanism 2 is disposed at the top of the medicine storage tank 1;

[0037] Fixing mechanism 3, which is installed at the bottom end of the medicine storage tank 1;

[0038] The pressing mechanism 4 is installed inside the fixing mechanism 3. The pressing mechanism 4 includes a telescopic pressing column 401. The bottom end of the telescopic pressing column 401 is provided with a drug dispensing ball 402. The top end of the telescopic pressing column 401 is fixedly connected with a compression spring 403. A telescopic drug dispensing column 404 is inserted inside the telescopic pressing column 401. The top end of the telescopic drug dispensing column 404 is provided with a drug infiltration groove 405. The top end of the telescopic drug dispensing column 404 is fitted with a drug infiltration chamber 406.

[0039] A connecting mechanism 5 is installed on one side of the pressing mechanism 4. The connecting mechanism 5 includes a rack plate 501, a rotating gear 502 meshing with the outside of the rack plate 501, a fixed rod 503 installed on the outside of the rotating gear 502, a toothed rod 504 meshing with the outside of the rotating gear 502, and a sliding seat 505 connected to one side of the toothed rod 504.

[0040] The applicator 6 is fixedly connected to the bottom end of the connecting mechanism 5. The fixing mechanism 3 includes a first mounting collar 301, with a plurality of first insertion slots 302 extending through the outside of the first mounting collar 301. A second mounting collar 304 is fixedly connected to the bottom end of the first mounting collar 301, and a mounting plate 303 is fixedly connected to the bottom end of the second mounting collar 304. A plurality of second insertion slots 305 extend through the outside of the second mounting collar 304.

[0041] Specifically, the telescopic dispensing column 404 is inserted into the first insertion slot 302, while the telescopic pressing column 401 is inserted into the second insertion slot 305. The telescopic pressing column 401 can slide flexibly up and down in the second insertion slot 305, while the telescopic dispensing column 404 can also slide smoothly in the first insertion slot 302. Both are precisely fitted and guided, ensuring stability and guiding accuracy during movement. Furthermore, a sliding seat 505 is fixedly connected to the bottom of the mounting plate 303. This sliding seat 505 provides a reliable sliding track and positioning support for the toothed rod 504, ensuring that the toothed rod 504 maintains a straight line under the guidance of the sliding seat 505 during vertical movement. The stability of the movement effectively avoids deviation or shaking, thereby improving the operating accuracy and reliability of the entire transmission system. At the same time, a freely rotatable drug dispensing ball 402 is movably installed at the bottom end of the telescopic pressing column 401. This drug dispensing ball 402 not only maintains good contact with the patient's skin under the push of the telescopic pressing column 401, but also rolls flexibly with the movement of the device, so as to evenly and delicately apply the medicine released from inside the telescopic drug dispensing column 404 through the drug infiltration groove 405 and drug infiltration chamber 406 to the skin surface. This not only improves the uniformity of drug distribution, but also promotes the contact between the skin and the drug through the slight massage action of the ball, further enhancing the drug penetration effect and absorption efficiency, and achieving a more precise, comfortable and efficient drug application experience.

[0042] As can be seen from the above, when a pressing operation is applied to the medicine storage tank 1, the telescopic pressing column 401 inside will move flexibly in and out under the elastic action of the compression spring 403, thereby driving the telescopic lower medicine column 404 connected to it to slide smoothly up and down and adjust in and out inside the first mounting collar 301. During this process, the user can precisely adjust the alignment of the seepage groove 405 with the corresponding holes and slots on the seepage chamber 406 located below by controlling the amount of pressing force. When only a shallow pressing operation is performed, only the bottom set of seepage grooves 405 is aligned with the bottom hole and slot of the seepage chamber 406. At this time, the medicine in the medicine storage tank 1 can only achieve slight and appropriate seepage, thereby ensuring that only a small amount of medicine is released. When the user increases the pressing force on the medicine storage tank 1, the telescopic pressing column 401 will move further downward, so that the three rows of seepage grooves 405 are aligned with the corresponding holes on the seepage chamber 406 in sequence. The grooves are fully aligned, allowing for sufficient and abundant penetration of the medication, ensuring that more medication is evenly dispensed. This allows users to precisely control the amount of medication released from the storage tank 1 by flexibly adjusting the pressure applied, achieving precise on-demand medication delivery. Simultaneously, a freely rotating dispensing ball 402 is located at the bottom of the telescopic dispensing column 401. When the medication is dispensed through the corresponding holes in the penetration groove 405 and penetration chamber 406, the dispensing ball 402 rolls flexibly upon contact with the patient's skin. This not only helps to evenly and delicately spread the medication inside the telescopic dispensing column 404 but also further enhances the contact effect between the medication and the skin, ensuring that the medication is applied precisely and appropriately to the affected area. This allows for flexible and precise adjustment of the final medication dispensing amount based on different pressure levels, meeting the refined needs for medication control in different treatment scenarios.

[0043] refer to Figure 2 and Figure 6As shown, the top end of the compression spring 403 is fixedly connected to the bottom end of the first mounting collar 301. The dispensing ball 402 is mounted on the bottom end of the telescopic pressing column 401 via a limiting plate. The dispensing ball 402 is rotatably connected to the bottom end of the telescopic pressing column 401. The telescopic pressing column 401 is slidably connected inside the second mounting collar 304. The infiltration chamber 406 is fixedly connected to the top end of the first mounting collar 301. The inner sidewall of the infiltration chamber 406 has a slot of the same size as the infiltration groove 405, and the slot is aligned with the opening position of the infiltration groove 405. The medicine infiltration groove 405 is horizontally provided with three sets at the top of the telescopic medicine column 404. The rack plate 501 is fixedly connected to the outside of one side of the telescopic pressing column 401. The top of the fixing rod 503 is fixedly connected to the bottom of the second mounting collar 304. The top of the sliding seat 505 is fixedly connected to the bottom of the mounting plate 303. The rack plate rod 504 is slidably connected to the outside of the sliding seat 505. The rotating gear 502 is rotatably connected to the outside of the fixing rod 503. The pressing mechanism 4 and the connecting mechanism 5 are provided in multiple sets inside the fixing mechanism 3.

[0044] Specifically, when the telescopic pressing column 401 is raised and lowered under the action of external force, the rack plate 501 fixed on its outer side will move along with it. Through precise meshing with the rotating gear 502, the linear motion of the telescopic pressing column 401 is converted into the rotational motion of the rotating gear 502, thereby driving the rotating gear 502 to rotate synchronously. The other side of the rotating gear 502 is meshed with the toothed rod 504. Therefore, during the rotation of the rotating gear 502, it can further drive the toothed rod 504 to move stably along its guide track. The height adjustment mechanism allows for precise control and release of the medicine in the medicine tank 1 when the user applies downward pressure to the telescopic pressing column 401. Simultaneously, it drives the toothed rod 504 to move downward, thereby applying a downward pushing force to the application mechanism 6 connected to it. This causes the application mechanism 6 to extend downward and fit tightly against the patient's skin surface. This linkage design enables the application device to automatically complete the application component's contact with the skin while pressing to apply the medicine, ensuring that the application block 603 maintains appropriate contact pressure with the skin.

[0045] Example 2:

[0046] refer to Figures 1-6As shown, the screwing mechanism 2 includes a bottle cap seat 201, a connecting cover 202 is sleeved on the outside of the bottle cap seat 201, an anti-slip groove 203 is provided on the outside of the medicine storage tank 1, and a threaded groove is provided on the outside of the bottle cap seat 201. The connecting cover 202 is screwed onto the outside of the bottle cap seat 201 by matching the threaded groove on the bottle cap seat 201. Two anti-slip grooves 203 are symmetrically arranged on the outside of the medicine storage tank 1. The application mechanism 6 includes a fixing plate 601, a telescopic spring 602 is fixedly connected to the bottom end of the fixing plate 601, and an application block 603 is fixedly connected to the bottom end of the telescopic spring 602. The fixing plate 601 is elastically telescopically connected to the application block 603 through the telescopic spring 602. The application block 603 is a hemispherical hollow structure, and the fixing plate 601 is slidably connected inside the application block 603.

[0047] Specifically, when adding medicine, by rotating the connecting cap 202, the connecting cap 202 can be removed from the bottle cap seat 201, so that the medicine can be poured into the medicine storage tank 1 through the bottle cap seat 201. The anti-slip groove 203 can improve the stability of the device during use and increase the friction during use. The elastic extension and contraction between the application block 603 and the telescopic spring 602 can make the application block 603 evenly adhere to the surface of the skin according to the different downward pressure of the telescopic pressing column 401.

[0048] As can be seen from the above, when the telescopic pressing column 401 is pressed downwards, it can move smoothly up and down inside the device. At the same time, the rack plate 501 set on the side of the telescopic pressing column 401 moves synchronously and drives the rotating gear 502 to rotate through precise meshing with it. During the rotation of the rotating gear 502, it drives the application mechanism 6 to move in the opposite direction to the downward pressing of the telescopic pressing column 401 through meshing with the rack plate rod 504 on the other side. This allows the application mechanism 6 to actively move towards the patient's skin and perform a contact operation. When the entire application device moves and applies medication to the patient's skin, the application block 603 at the front end of the application mechanism 6 can maintain good contact with the skin and provide uniform and gentle friction to the skin during the movement, which not only effectively improves the application of the medication on the skin surface. The uniform distribution of the medication avoids excessive or insufficient local application. The gentle friction also appropriately raises the temperature of the skin surface, promoting pore dilation and blood circulation, accelerating drug penetration and absorption, and enhancing efficacy. Furthermore, a buffering telescopic spring 602 is installed between the application block 603 and the fixing plate 601. This spring automatically adjusts the contact pressure between the application block 603 and the skin based on the varying downward pressure applied to the telescopic pressing column 401. This ensures a uniform and close fit to the skin surface regardless of whether the pressure is light or heavy, preventing discomfort due to excessive pressure or insufficient application of the medication. This allows for flexible adjustment of the application pressure according to actual needs, ensuring the medication is applied evenly and efficiently to the skin, improving the overall application experience and treatment effect.
