Description

Technical Field

[0001] The utility model relates to the technical field of medicine applicators, in particular to a medicine applicator with convenient length adjustment. Background Art

[0002] A drug applicator, also known as a smear-type applicator, is a device used for injection, care and protection. It is mainly used to apply drugs, care agents or protective agents to specific parts. It has the characteristics of ease of use, precise control and efficient absorption. It is widely used in medical treatment, nursing and personal protection. According to different usage requirements, smear-type applicators can be divided into many types. Common types include roller applicators, spray applicators and brush head applicators.

[0003] There are many types of medicine applicators on the market. When using them, some ointment is stuck to the bottom end of the applicator head, and the handle is used to drive the applicator head to apply the ointment on the skin surface at a uniform speed. Depending on the application position, the holding position of the handle will also change accordingly. Since the handle is a single stick, its length has certain limitations. This leads to the ointment being difficult to apply evenly when the application position is far away due to insufficient handle length, which often causes inconvenience to the user.
