Description

Technical Field

[0001] This utility model relates to the field of medical devices, and in particular to a device for applying topical medicines. Background Technology

[0002] Personalized dermatological medications are typically stored in a simple container. To use them, the container is opened, and the medication is applied to the wound using a cotton swab. However, this type of container has the following drawbacks:

[0003] 1. Patients often forget to close the container after use, which can contaminate some medications that require airtight storage.

[0004] 2. Some patients (especially older patients) will reuse a single cotton swab to save on cotton swabs. For example, if a single application of medication requires 3-4 applications, the patient will soak the same cotton swab back into the liquid in the medicine bottle after applying it to the affected area. This can easily contaminate the liquid in the bottle and ultimately lead to secondary bacterial infection of the patient's affected area.

[0005] 3. Cotton swabs are only suitable for applying to small areas. When applying to large areas, the process of soaking and applying the cotton swab takes a long time, which is inconvenient for patients.

[0006] Therefore, this case is brought. Utility Model Content

[0007] The purpose of this invention is to provide a device for applying external medicines to facilitate patient use and prevent contamination of the medicine.

[0008] To achieve the above objectives, the technical solution of this utility model is as follows:

[0009] A topical medicine application device includes a bottle body and a cap body that can be connected by threads. The top surface of the cap body has a protruding column at its center and a plurality of liquid outlet holes. The column body includes a cylindrical sealing section at the top and a frustum-shaped closing section at the bottom. The two ends of the frustum-shaped closing section are integrally formed with the bottom surface of the cylindrical sealing section and the top surface of the cap body, respectively, and the outer diameter gradually decreases from top to bottom.

[0010] The device includes a lifting plate that is slidably connected to the cover. The lifting plate is located above the top surface of the cover and has a through hole in the center. The column passes through the through hole. The cylindrical sealing section can be sealed with the inner wall of the through hole. There is a gap between the frustum-shaped closing section and the inner wall of the through hole. A reset mechanism is provided between the lifting plate and the cover. The highest position of the lifting plate is exactly flush with the top surface of the column. The top surface of the lifting plate is provided with a soft brush.

[0011] Furthermore, the bottle body is a light-proof bottle body.

[0012] Furthermore, the outer periphery of the cover is provided with a mounting cavity with a top opening, the outer periphery of the lifting plate is provided with an annular guide plate, the upper end of the annular guide plate is fixed to the lifting plate, the lower end enters the mounting cavity, a reset spring is provided between the bottom surface of the annular guide plate and the bottom surface of the mounting cavity, the portion of the annular guide plate located in the mounting cavity is provided with a limiting step, and the inner wall of the opening of the mounting cavity is provided with a retaining ring that cooperates with the limiting step.

[0013] Furthermore, it includes a protective cover for protecting the soft brush, which can be snapped onto the lifting plate.

[0014] Furthermore, the outer wall of the cylindrical sealing section is wrapped with a silicone layer.

[0015] Furthermore, the top surface of the lifting plate includes, in radial direction from the outside to the inside, a horizontal part, a frustum-shaped recessed part, and the through hole, and the soft brush is disposed on the inclined surface of the frustum-shaped recessed part.

[0016] The advantages of this invention are as follows: the application device achieves automatic closure of the medicine outlet by setting up a lifting plate and a variable diameter column. When in use, pushing the lifting plate creates a gap between the through hole and the column, allowing the medicine to flow out through the gap and wet the soft brush. Releasing the lifting plate creates a seal between the through hole and the column, preventing contamination of the medicine in the bottle and also preventing patients from contaminating the medicine in the bottle with cotton swabs. At the same time, the soft brush can achieve large-area even application of the medicine to the wound, which is convenient and quick. Attached Figure Description

Detailed Implementation

[0023] The present invention will be further described in detail below with reference to the embodiments. It should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc. indicated by the accompanying drawings are only for the convenience of describing the present invention and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the present invention.

[0024] This embodiment proposes a device for applying topical medicines, such as... Figures 1 to 4 As shown, a bottle body 1 and a cap body 2 are connected by threads. After the cap body 2 is unscrewed, the medicine can be added into the bottle body 1. The top surface of the cap body 2 has a protruding column 3 at its center, and the top surface of the cap body 2 has multiple liquid outlet holes 203. The multiple liquid outlet holes 203 are arranged around the column 3, and the medicine in the bottle body 1 can flow out through the liquid outlet holes 203. The column 3 includes a cylindrical sealing section 301 at the top and a frustum-shaped converging section 302 at the bottom. The upper and lower ends of the frustum-shaped converging section 302 are integrally formed with the bottom surface of the cylindrical sealing section 301 and the top surface of the cap body 2, respectively, and the outer diameter gradually decreases from top to bottom.

[0025] The applicator also includes a lifting plate 4 located above the top surface of the cover 2. The lifting plate 4 has a through hole 403 at its center, through which the column 3 protrudes. For example... Figure 3 As shown, the outer periphery of the cover 2 has a mounting cavity 201 with a top opening. The outer periphery of the lifting plate 4 has an annular guide plate 7. The upper end of the annular guide plate 7 is fixed to the lifting plate 4, and the lower end enters the mounting cavity 201. A return spring 8 is provided between the bottom surface of the annular guide plate 7 and the bottom surface of the mounting cavity 201. The portion of the annular guide plate 7 located within the mounting cavity 201 has a limiting step 701. The inner wall of the opening of the mounting cavity 201 has a retaining ring 202 that cooperates with the limiting step 701. In the initial state, the lifting plate 4 is lifted by the return spring 8 through the annular guide plate 7 until the limiting step 701 contacts the retaining ring 202 and stops. By pressing the lifting plate 4, the lifting plate 4 can overcome the resistance of the return spring 8 and descend. Figure 2 As shown, when the lifting plate 4 is lifted by the reset spring 8, the cylindrical sealing section 301 and the inner wall of the through hole 403 are sealed together. At this time, if the medicine bottle is inverted, the medicine enters the liquid storage space between the lifting plate 4 and the top surface of the cap 2 through the liquid outlet 203, but cannot exit through the through hole 403 in the center of the lifting plate 4. When the lifting plate 4 is pressed down, a gap is created between the frustum-shaped converging section 302 and the inner wall of the through hole 403, such as... Figure 3 and Figure 4As shown, the medicine enters the liquid storage space between the lifting plate 4 and the top surface of the cover 2 through the liquid outlet 203 from inside the bottle 1, and then flows out of the liquid storage space through the gap through the through hole 403.

[0026] Preferably, when the lifting plate 4 is lifted to its highest position by the return spring 8, it is flush with the top surface of the column 3. To improve the sealing between the inner wall of the through hole 403 and the cylindrical sealing section 301, the outer wall of the cylindrical sealing section 301 in this embodiment is wrapped with a silicone layer. Of course, the gap between the annular guide plate 7 and the mounting cavity 201 should also be provided with a corresponding sealing structure to prevent the liquid medicine from entering the mounting cavity 201. This structure is existing technology and will not be described in detail here.

[0027] The top surface of the lifting plate 4 is equipped with a soft brush 5. Medication flowing from the through hole 403 can wet the soft brush 5, allowing the patient to apply the medication to the wound using the soft brush 5. Preferably, the application device includes a protective cover 6 for protecting the soft brush 5, which can be snapped onto the lifting plate 4. Figure 2 As shown, the top surface of the lifting plate 4 includes, from the outside to the inside, a horizontal part 401, a frustum-shaped recessed part 402, and a through hole 403 in a radial direction. The soft brush 5 is disposed on the inclined surface of the frustum-shaped recessed part 402. In use, the inverted bottle 1 is pressed against the affected area, and the soft brush 5 is deformed into the frustum-shaped recessed part 402 under force. At this time, the outer horizontal part 401 can contact the patient's skin to realize the transmission of thrust. The return spring 8 is compressed through the lifting plate 4 and the annular guide plate 7.

[0028] Preferably, the bottle body 1 is a light-proof bottle body to prolong the storage of the medicine.

[0029] The procedure for using this application device is as follows:

[0030] S1. The dermatologist prepares the medication individually, unscrews the cap 2 and injects the medication into the bottle 1, then screws the cap 2 back on.

[0031] S2. When the patient uses the medicine, the inverted medicine bottle is pressed against the affected area. The medicine enters the liquid storage space between the lifting plate 4 and the top surface of the cover 2 through the liquid outlet 203 from the bottle body 1. The force is applied so that the lifting plate 4 overcomes the spring resistance and approaches the top surface of the cover 2. During the movement of the lifting plate 4, a gap is generated between the inner wall of the through hole 403 and the column 3. The medicine in the liquid storage space flows out of the through hole 403 through the gap and wets the soft brush 5.

[0032] S3. The patient applies the ointment to the wound using a soft-bristled brush 5.

[0033] S4. Once the application is complete, stop applying pressure, the lifting plate 4 returns to its original position, and the medicine stops flowing out. Then clean the soft brush 5 to end the use.

[0034] It's important to note that the soft-bristled brush 5 can be cleaned every time or periodically (e.g., every 1 or 3 days). This method avoids contaminating the medication inside the bottle compared to soaking cotton swabs in the liquid.

[0035] The above embodiments are only used to explain the concept of the present invention, and are not intended to limit the protection of the present invention. Any non-substantial modifications made to the present invention using this concept should fall within the protection scope of the present invention.
