Embodiment 1
[0012] The vaginal applicator includes an outer tube (4) and a push rod (3), the push rod (3) extends into the outer tube (4) and can move relative to the outer tube (4). The front end of the outer tube (4) is provided with a cylindrical medicine cavity (1) with a slightly larger diameter that can contain medicine, and the rear end of the outer tube (4) is provided with a retaining ring (5). The propulsion rod (3) is provided with a medicine claw (2) at the front end. The medicine claw (2) is composed of four petal-shaped memory metal sheets. When the medicine claw (2) is in the medicine cavity (1), it is in the medicine cavity (1). Under the action of the wall, each memory metal piece is folded into a sac shape, and when the medicine claw (2) extends out of the medicine cavity (1), the memory metal piece is automatically opened. The propulsion rod (3) is provided with a propulsion plate (7) at the end, and a compression spring (6) is sleeved on the propulsion rod (3) between the ...
