Abstract
Description
Technical Field
[0001] This utility model belongs to the field of drug applicator technology, specifically a dermatological topical drug applicator. Background Technology
[0002] In dermatological treatment, topical medication is a common local treatment method suitable for various skin conditions, such as eczema, psoriasis, acne, skin allergies, and warts. When applying medication, the medication is first squeezed onto the affected area, then spread evenly using hands or tools.
[0003] When applying liquid medications to patients, a brush-equipped applicator is typically used. This applicator picks up the liquid medication and applies it to the wound for quick application. However, a single application may not be sufficient, requiring multiple dips. But after the applicator comes into contact with the wound, the brush may carry pathogens from the wound. Submerging the applicator in the liquid medication again can contaminate the medication, rendering it unusable.
[0004] Therefore, this utility model provides a topical dermatology medication applicator. Utility Model Content
[0005] In order to overcome the shortcomings of the prior art, at least one technical problem raised in the background art is solved.
[0006] The technical solution adopted by this utility model to solve its technical problem is as follows: The dermatological topical medication applicator of this utility model includes an applicator, the bottom of which is connected to an applicator brush via a clamping mechanism, and a medication dispensing mechanism is provided on one side of the applicator; the medication dispensing mechanism includes a connecting base fixedly installed with the applicator, a medicine box fixedly installed on the connecting base, a medicine inlet hole on the top of the medicine box, a liquid outlet on the bottom of the medicine box, and a plurality of liquid outlet tubes connected to the liquid outlet fixedly installed on the bottom of the medicine box, the bottom of the medicine box being inclined towards the liquid outlet; a protective mechanism is provided at the end of the liquid outlet tube away from the medicine box.
[0007] Furthermore, a sealing rod is slidably connected to one side of the medicine box, and a ball head is fixedly installed at one end of the sealing rod. A rubber sealing block is rotatably connected to the surface of the ball head.
[0008] Furthermore, the protective mechanism includes a protective cover that is rotatably connected to the liquid outlet pipe via a torsion spring. One side of the protective cover is fixedly fitted with an arc-shaped fixing rod made of rubber, and the surface of the liquid outlet pipe is provided with a fixing groove.
[0009] Furthermore, the clamping mechanism and the applicator are fixedly connected to a fixed frame. Inside the fixed frame, two sliding rods are symmetrically arranged. A connecting plate is fixedly installed at one end of each sliding rod. A spring is fixedly installed between the connecting plate and the fixed frame. A "U"-shaped clamping plate is fixedly installed at the ends of the two sliding rods that are close to each other.
[0010] Furthermore, two symmetrically arranged rubber pads are fixedly installed inside the clamping plate.
[0011] Furthermore, two symmetrically arranged limiting posts are fixedly installed on one side of the clamping plate. The limiting posts are made of rubber and gradually increase in size from the side closest to the clamping plate to the side furthest away from the clamping plate. A limiting groove adapted to the limiting posts is provided in the fixing frame.
[0012] The beneficial effects of this utility model are as follows:
[0013] 1. The dermatological topical medication applicator described in this utility model allows for rapid application of medication to a patient. Because the dispensing tube is located at the tip of the brush, when a medical professional applies the medication to a patient's wound, the medication first drips onto the wound. The applicator's brush then immediately applies the medication to the wound. The dispensing mechanism of this application allows for the storage of a certain amount of medication in a medicine box. When applying medication to multiple wounds on a patient, the cumbersome process of applying medication to one wound and then to the next is eliminated. Only the applicator needs to be carried, and the medicine box on the applicator controls the flow rate and position of the medication, achieving rapid, efficient, and precise application. Furthermore, after applying medication to one wound, the brush does not need to be dipped in medication again, thus preventing contamination of unused medication by the used brush.
[0014] 2. The dermatological topical medication applicator described in this utility model increases the gap between two clamping plates, facilitating the placement of the application brush into the fixed frame. After the application brush is placed, pushing the two connecting discs causes the connecting discs to move the sliding rod and clamping plates back to their original positions. At this time, the limiting post disengages from the limiting groove, and the clamping plates return to their original positions under the action of springs. The application brush is clamped by the cooperation of two "U"-shaped clamping plates and rubber pads. The four rubber pads are compressed and deformed when clamping the application brush, thereby increasing the friction between the rubber pads and the application brush and thus clamping it better. Furthermore, the two clamping plates, under the action of two springs, also clamp the application brush, ensuring that it will not fall off during use. The clamping mechanism designed in this application achieves the function of quickly clamping the application brush and also allows for quick removal and replacement of the application brush. When different patients need to apply the same medication, the application brush can be quickly changed using the clamping mechanism, greatly improving the efficiency of medication application and effectively preventing cross-infection between patients.

[0026] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.
[0027] like Figures 1 to 6 As shown in the embodiment of this utility model, a topical dermatological medication applicator includes an applicator 1, a medication brush 2 connected to the bottom of the applicator 1, and a medication dispensing mechanism 10 on one side of the applicator 1. The medication dispensing mechanism 10 includes a connecting seat 11 fixedly installed with the applicator 1, and a medication box 12 fixedly installed on the connecting seat 11. The top of the medication box 12 has a medication inlet hole, and the bottom of the medication box 12 has a liquid outlet 13. Several liquid outlet tubes 14 connected to the liquid outlet 13 are fixedly installed at the bottom of the medication box 12, and the bottom of the medication box 12 is inclined towards the liquid outlet 13. A sealing rod 15 is slidably connected to one side of the medication box 12, and a ball head 16 is fixedly installed at one end of the sealing rod 15. A rubber sealing block 17 is rotatably connected to the surface of the ball head 16.
[0028] Specifically, a protective mechanism 20 is provided at the end of the liquid outlet tube 14 away from the medicine box 12. The protective mechanism 20 includes a protective cover 21 that is rotatably connected to the liquid outlet tube 14 via a torsion spring. An arc-shaped fixing rod 22 made of rubber is fixedly installed on one side of the protective cover 21. A fixing groove 23 is provided on the surface of the liquid outlet tube 14.
[0029] When applying liquid medication to a patient, the liquid medication is first injected into the medicine box 12 through the inlet. Then, depending on the actual size of the patient's wound, the protective caps 21 at the bottom of several outlet tubes 14 are opened, allowing the fixing rods 22 on the protective caps 21 to be temporarily fixed into the fixing grooves 23 of the outlet tubes 14, facilitating the flow of the medication and achieving precise spraying, thus avoiding waste due to overuse. Next, the sealing rod 15 inside the medicine box 12 is slid, causing the sealing plate to slide via the ball head 16, opening the outlet 13 and allowing the medication to slowly flow out through the outlet 13 into the outlet tubes 14. Because the bottom of the medicine box 12 is inclined, the sealing plate is connected to the sealing rod 15 via the ball head 16, allowing the sealing plate to be adjusted to fit the shape of the bottom of the medicine box 12, thus enabling smooth sliding.
[0030] When it is time to apply the medication to the patient, since the dispensing tube 14 is at the front end of the brush, when the medical staff holds the medication to apply it to the patient's wound, the medication will first drip onto the patient's wound, and then the medication brush 2 at the bottom of the applicator 1 will immediately apply the medication to the wound, thereby achieving rapid application of the medication to the wound.
[0031] The medication application mechanism 10 designed in this application can store a certain amount of medication in the medication box 12. When applying medication to multiple wounds on a patient, medical staff no longer need to apply medication to each wound repeatedly, eliminating the cumbersome steps. They only need to carry the medication applicator 1, and use the medication box 12 on the applicator 1 to control the flow rate and position of the medication, achieving fast, efficient, and precise application. Furthermore, after applying medication to a wound, the brush does not need to be dipped in medication again, thus avoiding contamination of unused medication by the used brush and preventing contamination of unused medication.
[0032] The clamping mechanism 30 and the applicator 1 are fixedly connected to a fixed frame 31. Two sliding rods 32 are symmetrically arranged inside the fixed frame 31. A connecting plate 33 is fixedly installed at one end of each sliding rod 32. A spring 34 is fixedly installed between the connecting plate 33 and the fixed frame 31. A U-shaped clamping plate 35 is fixedly installed at the ends of the two sliding rods 32 that are close to each other. Two symmetrically arranged rubber pads 36 are fixedly installed inside the clamping plate 35. Two symmetrically arranged limiting posts 37, made of rubber, are fixedly installed on one side of the clamping plate 35. The limiting posts 37 gradually increase in size from the side closest to the clamping plate 35 to the side furthest away from the clamping plate 35. A limiting groove 38 adapted to the limiting posts 37 is provided inside the fixed frame 31.
[0033] During operation, before using the applicator 1, first pull the connecting plates 33 on both sides of the fixed frame 31, causing the connecting plates 33, along with the sliding rod 32, clamping plate 35, rubber pad 36, and limiting post 37, to slide away from the fixed frame 31. At this time, the rubber limiting post 37 will be squeezed and deformed, then inserted into the limiting groove 38, thereby fixing the clamping plate 35 and rubber pad 36. At this time, the gap between the two clamping plates 35 increases, making it easier to place the applicator brush 2 into the fixed frame 31. After the applicator brush 2 is placed, push the two connecting plates 33, causing the connecting plates 33 to drive the sliding rod 32 and clamping plate 35 to return to their original positions. At this time, the limiting post 37 leaves the limiting groove 38, and the clamping plate 35 returns to its original position under the action of the spring 34. The applicator brush 2 is clamped by the cooperation of the two "U"-shaped clamping plates 35 and the rubber pads 36. The four rubber pads 36 are squeezed and deformed when clamping the applicator brush 2, thereby increasing the friction between them and the applicator brush 2, thus clamping it better. Furthermore, the two clamps 35, under the action of the two springs 34, will also hold the medicine brush 2 in place, thus ensuring that it will not fall off during use.
[0034] The clamping mechanism 30 designed in this application enables the quick clamping of the medication brush 2, and also allows for quick disassembly of the medication brush 2. When different patients need to apply the same medication, the medication brush 2 can be quickly replaced by using the clamping mechanism 30, which greatly improves the efficiency of medication application and effectively prevents cross-infection between patients.
[0035] Working principle: When liquid medication needs to be applied to a patient, it is first injected into the medication box 12 through the inlet hole. Then, depending on the actual size of the patient's wound, the protective caps 21 at the bottom of several outlet tubes 14 are opened, allowing the fixing rods 22 on the protective caps 21 to be temporarily fixed into the fixing grooves 23 of the outlet tubes 14, facilitating the flow of the medication and achieving precise spraying, thus avoiding waste due to overuse. Next, the sealing rod 15 inside the medication box 12 is slid, causing the sealing plate to slide via the ball head 16, opening the outlet 13 and allowing the medication to slowly flow out through the outlet 13 into the outlet tubes 14. Because the bottom of the medication box 12 is inclined, the sealing plate is connected to the sealing rod 15 via the ball head 16, allowing the sealing plate to be adjusted to fit the shape of the bottom of the medication box 12, thus enabling smooth sliding. When it is time to apply the medication to the patient, since the dispensing tube 14 is at the front end of the brush, when the medical staff holds the medication to apply it to the patient's wound, the medication will first drip onto the patient's wound, and then the medication brush 2 at the bottom of the applicator 1 will immediately apply the medication to the wound, thereby achieving rapid application of the medication to the wound.
[0036] Before using the applicator 1, first pull the connecting plates 33 on both sides of the fixed frame 31, causing the connecting plates 33, along with the sliding rod 32, clamping plate 35, rubber pad 36, and limiting post 37, to slide away from the fixed frame 31. At this time, the rubber limiting post 37 will be squeezed and deformed, then inserted into the limiting groove 38, thereby fixing the clamping plate 35 and rubber pad 36. At this time, the gap between the two clamping plates 35 increases, making it easier to put the applicator brush 2 into the fixed frame 31. After the applicator brush 2 is placed, push the two connecting plates 33, causing the connecting plates 33 to drive the sliding rod 32 and clamping plate 35 to return to their original positions. At this time, the limiting post 37 leaves the limiting groove 38, and the clamping plate 35 returns to its original position under the action of the spring 34. The applicator brush 2 is clamped by the cooperation of the two "U"-shaped clamping plates 35 and the rubber pads 36. The four rubber pads 36 are squeezed and deformed when clamping the applicator brush 2, thereby increasing the friction between them and the applicator brush 2, thus clamping it better. Furthermore, the two clamps 35, under the action of the two springs 34, will also hold the medicine brush 2 in place, thus ensuring that it will not fall off during use.
