[0002] During dermatological treatment, it is often necessary to apply lotions or ointments to the patient's affected skin to directly treat the affected skin. However, since many ointments or lotions used to treat skin diseases are corrosive, in order to prevent corrosive damage to the healthy skin surrounding the affected skin, it is often necessary to apply a layer of vaseline to the healthy skin surrounding the affected skin before applying the lotion or ointment to the affected skin.

[0003] At present, most of the existing clinical applicators for skin and venereal diseases are simple in function. During use, it is not convenient to rotate the angle of the applicator brush, which is not conducive to operation. Moreover, it is not conducive to controlling the extrusion of the ointment, which is more troublesome to operate. Therefore, we propose a clinical applicator for skin and venereal diseases.
