Replacement cover for biochemical analyzer assembly line

Abstract

The invention discloses a replacement cover for a biochemical analyzer assembly line. The replacement cover comprises a shaft sleeve cover body, a flange edge and big-end-up conical sealing ring edges, the upper end of the shaft sleeve cover body is sealed, the upper outer wall of the cover body radially extends outwards to form the flange edge, the lower outer wall of the cover body radially extends outwards to form the big-end-up conical sealing ring edge, and the flange edge is provided with an annular groove. The replacement cover is further characterized in that axial opening grooves are formed in the peripheries of the conical sealing ring edges, the conical sealing ring edges include an upper conical sealing ring edge and a lower conical sealing ring edge, and the replacement cover is made of EVA (ethylene-vinyl acetate) materials. When used for the biochemical analyzer assembly line, the replacement cover can be automatically arranged, manual placement is omitted, the replacement cover can be easily pressed into a blood collection tube and pulled out from the blood collection tube, and working efficiency is remarkably improved.

Description

technical field [0001] The invention belongs to the field of medical supplies, and in particular relates to a replacement cap used for sealing a blood collection tube when it flows on a biochemical instrument assembly line. Background technique [0002] The process of testing the blood in the blood collection tube on the biochemical instrument assembly line is carried out during the circulation process. First, the cap with a relatively complicated structure at the mouth of the blood collection tube is removed, and then a replacement cap with a simple structure is replaced to prevent Blood overflows from the blood collection tube during the transfer. The replacement cover in the prior art includes a sleeve-shaped cover with the upper end sealed, a flange edge formed by extending the outer wall of the upper part of the cover radially outward, and a tapered seal formed by extending the outer wall of the lower part of the cover radially outward. ring edge. When in use, place t...

Problems solved by technology

However, when this kind of replacement cover is used in the biochemical instrument assembly line, because it cannot be arranged automatically, it needs to be placed manually, so it is troublesome and time-consuming, which affects work efficiency; on the other hand, the elasticity of the conical sealing ring is insufficient, and the conical sealing The deformation of the ring edge is small, and it is difficult to press into the blood collection tube and pull it out from the blood collection tube
