Abstract

The invention provides a female-rat vaginal-smear sample collection device. The female-rat vaginal-smear sample collection device comprises a vagina built-in head and a normal saline pusher. The quantitative normal saline pusher is adopted, and the consistency of normal saline for sampling is guaranteed. In the vagina built-in head, a cervix end and an orificium vaginae end are fixed for guaranteeing the consistency of a sampling part; a soft material is used in the cervix end, and operational friction stimulation is reduced; meanwhile, the flow direction of the normal saline entering the vagina can be changed to be outwards, the cervix is protected, infection caused when the normal saline reversely flows is avoided, and infection caused when cells of the inner wall of the vagina are injured is avoided in the mode that once washing is carried out with saline. In the operation process, the normal saline can be kept in the aseptic condition, and the animal infection rate in the operation process is reduced; the vagina built-in head can be disinfected and washed to be reused.

Description

technical field [0001] The invention belongs to the technical field of animal medicine, and in particular relates to a female rat vaginal smear sample collection device. Background technique [0002] Vaginal smear is an important means to evaluate the ovarian function of female rats in scientific research experiments. At present, there are many methods that use a sterile cotton swab wetted with normal saline, rotate it and insert it into the vagina of the animal, and then take it out for smear after gently rotating it a few times in the vagina; or use a dropper or pipette to absorb the normal saline and place it The vaginal opening was aspirated repeatedly to obtain vaginal exfoliated cells. Generally, 4-5 consecutive days of vaginal smears are required to observe periodic changes. [0003] The current method for sampling exfoliated cells from vaginal smears has relatively poor operational consistency; there may be uneven application of force in the vaginal rotation of ste...
