Vaginal secretion sampling device for obstetrics clinical application

Abstract

The invention relates to the field of medical tools, and particularly discloses a vaginal secretion sampling device for obstetrics clinical application, which comprises a support rod, a sampling headand a grip, the sampling head is connected to one end of the support rod, the other end is connected with the grip, the sampling head is an egg-shaped hollow structure, the side wall of the sampling head is spaced apart from at least one notch, the outer wall of the sampling head is provided with an arc-shaped protrusion on a side of the notch, the inner wall of the sampling head is fixedly disposed with a limit position on one side of the notch, the support rod and the handle are provided with an active passage along the axial direction, and the movable passage is provided with a connecting rod. The device is used for sampling by the sampling head. After the sampling head extends into the vagina, the vaginal secretions flow into the sampling head through the notch, and the sampling head is rotated to scrape the secretion at the inner wall of the vagina into the sampling head through the arc-shaped protrusion, the efficiency of sampling is improved, and the usage is more convenient.

Description

technical field [0001] The invention relates to the field of medical tools, in particular to a vaginal secretion sampling device used in obstetrics clinics. Background technique [0002] Medical devices refer to instruments, equipment, utensils, in vitro diagnostic reagents and calibrators, materials, and other similar or related items that are directly or indirectly used on the human body, including required computer software. The effect is mainly obtained through physical methods, not through pharmacological, immunological or metabolic methods, or although these methods are involved, they only play an auxiliary role. The purpose is diagnosis, prevention, monitoring, treatment or mitigation of disease; diagnosis, monitoring, treatment, mitigation or functional compensation of injury; examination, replacement, regulation or support of physiological structures or physiological processes; life support or maintenance; pregnancy control; To provide information for medical or di...

Problems solved by technology

[0003] During obstetric examination, it is often necessary to sample and test women's vaginal secretions. However, most of the existing sampling tools are simple in structure, which will bring strong discomfort to women during the adoption process, and the sampling efficiency is low. It is difficult to take out and store samples, which cannot meet the needs of use. Therefore, we have designed a vaginal secretion sampling device for obstetrics clinics to solve the above problems
