Description

TECHNICAL FIELD

[0001] The utility model relates to medicine applying tool technical field, especially the utility model relates to a medicine applying device and system for back or scalp medicine applying. BACKGROUND

[0002] In daily life, people often encounter situations that require self-applying medicine, especially when dealing with scalp problems (such as hair loss, dermatitis) or large-area skin problems on the back (such as acne, eczema). However, these areas are often difficult to reach or fully cover by oneself, making uniform application of medicine difficult, or even impossible to apply to the exact location, thereby affecting the treatment effect.

[0003] Traditional manual application not only has low efficiency, but also is prone to omissions or over-application, affecting the drug effect and possibly causing unnecessary irritation to healthy skin. Secondly, medicine is prone to dripping, leading to waste of medicine. Thirdly, manual application can lead to hand bacterial transmission, increasing the risk of infection. Due to the difficulty of self-applying medicine to parts such as the scalp and back, especially for patients with limited mobility, using traditional methods often feels difficult.

[0004] In existing solutions, some auxiliary tools are designed to help with application, such as long-handled ointment brushes or sponge sticks. First of all, these products often cannot adapt to the complex curved structure of the head and back. Secondly, during application, the application position cannot be seen, making it difficult to ensure accuracy and coverage, and causing fatigue. Thirdly, the existing medicine applying device can only be used singly, such as only applying to the back or only applying to the scalp, and cannot be flexibly switched, and is inconvenient to clean.

[0005] For the problems of inaccurate medicine application coverage, uneven medicine application, inability to flexibly switch medicine application methods, and difficulty in cleaning in the related art, no effective solutions have been proposed. SUMMARY
