Clinical vaginal secretion sampling device

Abstract

The invention provides a clinical vaginal secretion sampling device. The clinical vaginal secretion sampling device comprises a cylinder, wherein a piston is slidably mounted in the cylinder; a push-pull rod is mounted on one side of the piston; a cylinder ring is mounted at the end, away from a cross rod, of the cylinder; a first external thread ring is fixed to one end of the cylinder ring; a second external thread ring is fixed to the end, away from the first external thread ring, of the cylinder ring; an internal thread cylinder is connected to the second external thread ring in a threaded mode; an external thread pipe is fixed to the end, away from the cylinder ring, of the internal thread cylinder; an insertion pipe is arranged on the external thread pipe in a sleeving mode; a check block is installed in the cylinder ring; a connecting pipe is installed in the middle of the face, facing the piston, of the check block; and the end, away from the check block, of the connecting pipe is sleeved with an expansion air bag, and the connecting pipe and the expansion air bag adhere to each other. Compared with the prior art, the device of the invention has the following beneficial effects that vaginal secretion is prevented from being attached to the surface of the piston, and the effect of hiding and protecting the external threaded pipe is further achieved.

Description

technical field [0001] The invention relates to a clinical vaginal secretion sampling device, which belongs to the field of medical equipment. Background technique [0002] During the examination in the obstetrics department, it is often necessary to sample and test the vaginal secretions of women. The piston is twitched to slide in the cylinder to form a negative pressure in the cylinder, and then the intubation tube is inserted in the vagina to facilitate the collection of vaginal discharge under negative pressure. During use, due to the lack of a separation structure between the piston and the cannula, the vaginal secretions tend to adhere to the surface of the piston. After use, many parts need to be disassembled and cleaned, which increases the difficulty of cleaning. It is easy to damage the piston and other parts during the process. Contents of the invention [0003] In view of the deficiencies in the prior art, the purpose of the present invention is to provide a ...
