Sampling device

Abstract

The invention provides a sampling device, which comprises an inner pipe, the inner pipe is provided with an inner pipe closed end, an inner pipe open end and a longitudinally extending inner pipe body, and one side of the inner pipe body is provided with a sampling port; an outer pipe which is provided with an outer pipe closed end, an outer pipe open end and a longitudinally-extending outer pipebody, and the inner pipe is contained in the outer pipe body; a cover body which comprises a cover main body and a sealing bolt connected with the bottom end of the cover main body; wherein an annulargroove is formed in the joint of the cover body and the sealing bolt, and the outer side wall of the annular groove is provided with an arc face which makes contact with the outer side wall of the open end of the outer pipe and extends outwards. According to the sampling device, the cambered surface contacted with the outer pipe is arranged at the annular groove of the cover body, so that the contact force of the cover body and the pipe body is uniformly dispersed on the cambered surface when the cover body is opened towards the outer side and taken down, and the stress generated in the coverbody is reduced; and the cover body can be opened towards the outer side only by slightly exerting force, so that liquid in the inner pipe is prevented from shaking and splashing out.

Description

technical field [0001] The invention relates to a sampling device, which is especially suitable for collecting urine and belongs to the technical field of medical treatment. Background technique [0002] Urine needs to be collected during the urine test, but most of the urine collection devices used at this stage are simple urine sample collection cups, which directly accept the urine in the collection cup, and then hand it over to the staff to pour it into the test tube , there are many problems in this process, for example, urine is easily splashed to the outside of the collection cup due to insufficient convenience during collection, which affects hygiene; the surrounding environment is easily polluted during the collection of urine in the collection cup into the test tube, and the test tube It is also very inconvenient when transferring. [0003] CN1276868A discloses a container for urine collection, which includes an elongated cylindrical container body with one end cl...

AI Technical Summary

Problems solved by technology

When the liquid is collected in the inner tube, since the contact surface between the inner wall of the cover and the outer wall of the upper end of the outer wall of the cover tube is an inclined surface, it takes a lot of force to remove the cover, which not only produces a lot of stress on the inner wall of the cover, but also may The liquid in the inner tube will slosh and splash out
