Description

Technical Field

[0001] The utility model relates to a scalp application device, in particular to a minoxidil solution scalp medication and application device. Background Art

[0002] In the prior art, there are many liquid application devices for applying liquid medicine or cosmetics to the scalp, such as spray-type or comb-type devices, but there are still many problems.

[0003] The spray-type application device is easy to use, but the spray cannot reach the bottom of the scalp and hair roots, and cannot produce a massaging effect on the scalp and cannot effectively penetrate into the hair roots.

[0004] The comb-type applicator is provided with a plurality of tube structures for dripping liquid onto the scalp. However, since most applicators are made of plastic, the ends of the tubes are generally rough and the surface treatment is poor. When used on the scalp, the scalp skin may be abraded, causing irritation and leading to scalp allergies.

[0005] On the other hand, the comb-type applicator generally does not have a quantitative structure, and therefore can only be used for non-medicinal solutions or conventional hair oils, scalp solutions, etc., and cannot be used for liquid medicines or cosmetic solutions that require precise or approximate quantitative dosages. Utility Model Content

[0006] The utility model provides a scalp application device, the purpose of which is to overcome the above-mentioned deficiencies in the prior art, to improve the comfort and effectiveness of use, and to achieve quantitative liquid delivery.

The metering chamber is provided with a filling valve on one side of the liquid storage container, and an emptying valve on the other side of the metering chamber on the other side of the connecting tube. When the filling valve is open, the liquid storage container communicates with the metering chamber, and when the emptying valve is open, the metering chamber communicates with the connecting tube. The filling valve and the emptying valve are opened at different times, and the connecting tube is connected to a plurality of liquid delivery tubes via a connecting passage. When the liquid storage container is inverted, the liquid storage container and the metering chamber are rotated relative to each other to switch the filling and emptying valves between open and closed. When the filling valve is open, liquid enters the metering chamber from the liquid storage container in a fixed amount, and when the emptying valve is open, liquid enters the liquid delivery tube through the connecting tube and the opening, and is applied to the scalp via the sphere, achieving fixed amount application.

[0008] Preferably, the liquid storage container is a plastic container coated with stainless steel inside, which can meet the storage needs of various liquids.

[0009] Preferably, the connecting channel is a plastic tube with one or two openings for transporting liquid from the connecting tube to the liquid delivery tube.

[0010] Preferably, the liquid delivery tube is a plastic tube coated with a metal coating on the outside, which can improve the comfort of use.

[0011] Preferably, the liquid delivery tube is a flexible tube with a metal or plastic spring on the outside, so that the height can be adjusted according to the skin surface.

[0012] Preferably, the outer end of the liquid delivery tube is wrapped with a sphere, which is used to deliver the liquid to the scalp and has a massage effect to increase penetration.

[0013] Preferably, the sphere is a steel ball, which has excellent use effect.

[0014] Preferably, the liquid storage container stores 5% minoxidil solution.

[0054] As the most preferred embodiment, the liquid delivery pipe 7 is made of plastic material and coated with a metal coating on the outside.

[0055] As a further embodiment, the height of the liquid delivery tube 7 is about 0.1-5 mm, preferably 0.3-3 cm, and most preferably 0.5-2 cm.

[0056] As another embodiment, the height of the liquid delivery tube 7 can be adjusted in any manner according to the skin surface to which the liquid is to be applied.

[0062] Example 1: Preparation of solution

[0063] Prepare a 5% minoxidil solution for use in a scalp application device.

[0064] Serial number Components effect concentration 1 Minoxidil Active drug 5% w / v 2 Propylene glycol solvent 70% w / v 3 Ethanol 96% Cosolvent / Penetration Enhancer 20% w / v 4 purified water carrier qsto100ml

[0065] Preparation Method: Dissolve minoxidil in propylene glycol while stirring. Add 96% ethanol while stirring and mix thoroughly. Slowly add purified water while stirring and continue stirring for 30 minutes. The resulting solutions are then loaded into the scalp application device of the present invention and a commercially available scalp application device, respectively.

[0066] Example 2: Volume Measurement

[0067] The sample volume of the solution of Example 1 was measured using 1 ml of Quantification Chamber 2 to confirm its accuracy, and the results are recorded in the table below.

[0068]

[0069]

[0070] The accuracy and measurement precision of the scalp application device of the present invention are comparable to those of commercially available scalp application devices, proving that the scalp application device of the present invention can accurately quantify the volume of liquid.

[0071] Example 3: Permeation studies

[0072] A 5 cm x 5 cm piece of pig skin, along with the hair, was carefully separated and the subcutaneous fat attached to the dermis was carefully removed from the bottom of the skin. The prepared skin slice was carefully clamped on a glass plate with the stratum corneum facing upwards.

[0073] Using the present invention's scalp application device and a commercially available scalp application device, 0.5 ml of the solution obtained in Example 1 was applied to the skin, followed by massage using the present invention's scalp application device. After 5 minutes of massage, the solution was carefully rinsed off with saline and collected. The collected solution and skin samples were homogenized with saline and analyzed for minoxidil content. Six samples were collected for both types of samples. The results are recorded below.

[0074]

[0075]

[0076] It can be seen that the application device with a ball at the end of the tube of the utility model greatly improves the penetration rate of minoxidil. It is speculated that the massage effect and the movement of the hair roots create a gap between the hair shaft and the skin, allowing more drug solution to penetrate through the newly opened pores.

[0077] Example 4: Usage Study

[0078] Twenty people were each given two applicators and asked to evaluate each for 15 days. After 30 days of use, feedback was recorded. Each person was asked to provide either positive or negative feedback on the applicator.

[0079]

[0080] As shown in the above table, the device of the utility model has a better feedback effect.

[0081] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the creative concept of the present invention, which all fall within the scope of protection of the present invention.
