Abstract

The invention relates to an injector which is installed on an automatic cell sedimentation tablet compressing machine and conducts rapid abstraction and push on the liquid sample of cast-off cells that contain rather much mucilage. The injector is characterized in that a plug is inserted into the needle tube of the injector and provided with at least two groove channels which are internally communicated with the tube of the injector. The injector can abstract and push sample more rapidly, the sample does not spill over and the channel is not blocked completely, thus being conducive to realizing automation. A mould used for manufacturing the utility model is simple and the assembly of semi-manufactured goods is convenient; therefore, the injector which has low cost and is disposable to prevent crossing contamination can be manufactured on a large scale.

Description

technical field [0001] The present invention relates to a device capable of extracting and injecting liquid specimens for cell testing, especially a syringe installed on an automatic cell sedimentation tablet machine for rapidly extracting and injecting liquid specimens of exfoliated cells containing more mucus. Background technique [0002] The needle injection hole of known syringe is a small straight hole. When the mucus sample wrapped in exfoliated cells is repeatedly and quickly pushed with a syringe, due to the impact of the strong pressure of the syringe and the extrusion of the mucus in the micro-pipe, the large pieces of mucus are torn apart, and the exfoliated cells that are wrapped are separated and released. , to facilitate the inspection of cells. However, since the injection hole of ordinary needles is a small straight hole, the liquid ejected vertically at high speed is likely to splash out of the container and cause pollution, and the single micro-pipe is sl...
