Abstract
The utility model relates to an injector mounted on an automatic cell settlement and sheet processing machine for rapidly sucking and injecting liquid specimen of exfoliated cells containing more mucilage. The injector is characterized in that a plug is mounted in the injector tube; and at least two channels communicated with the injector tube are formed on the plug. The injector can suck specimen more rapidly without spattering the specimen, and can prevent the channels from being blocked completely. The injector has the advantages of easy automation, simple and feasible die manufacture, convenient assembly of semi-products, large-scale production, low production cost, disposable use, as well as no crossed contamination.
Description
Technical field
The utility model relates to a kind of device that can extract and inject liquid sample when being used for cellular assay, especially is installed in the syringe that on the automated cell sedimentation pelleter cast-off cells liquid sample that contains more mucus is extracted fast and injects.
Background technology
The needle injection hole of known syringe is a tiny straight hole.Take out fast repeatedly when pushing away the mucus sample that is wrapped in cast-off cells with syringe, because percussive action and the squeezing action of mucus in microtubule that the syringe crunch produces, bulk mucus is torn, and the cast-off cells that are wrapped is separated discharge, and is convenient to the check of cell.But because common needle injection hole is a tiny straight hole, the easy splash of liquid of vertical ejection pollutes outside container at a high speed, and single microtubule to take out the speed of pushing away slow, stopped up fully by mucus easily again, cause difficulty to test.
Summary of the invention
Existing syringe test speed is slow in order to overcome, the deficiency of splash pollution and line clogging, the utility model provides a kind of syringe with a plurality of fine side opening pipelines, not only can not make the liquid splash when this syringe is injected outside container, can not stopped up fully, and test speed be very fast yet.
The technical scheme that its technical matters that solves the utility model adopts is: a kind of syringe that is used for cellular assay, form by syringe tube and syringe piston rod, it is characterized in that a syringe chock plug is installed on the needle tubing of syringe tube, have at least on the syringe chock plug in two passages and the syringe tube to be connected.The syringe chock plug is divided into stick harness and obturating plug, and stick harness is cylindric, and obturating plug is round table-like, and several grooves that distributing on stick harness, these grooves run through whole stick harness and extend to outside the obturating plug always.Needle tubing on the syringe tube has certain length, and the needle tubing front inner wall is an inclined-plane from inside to outside.The syringe chock plug is inserted in the syringe intracavity of syringe, the stick harness of syringe chock plug is overlapped with needle interior wall, and obturating plug overlaps fully with the beveled walls of needle tubing front end, installs syringe piston rod, like this, syringe has just had a plurality of fine injection canals to the side under shed.When the sample in the bolus infusion device, the direction that sample ejects is under the side, and sample is run into to turn back behind the chamber wall and also only can be spattered on container opposite side tube wall, can splash not go out outside the container.Because of on different directions, distributing a plurality of access portal, when extracting sample, if a certain passage is by mucus plugging, because of other passage still unobstructed, sample still can enter into syringe, when injecting sample, blocked passage can be got through again again, and passage has been obtained solution by complete blocking problem like this.And the multichannel speed of injecting is single pass several times.
The beneficial effects of the utility model are, can take out faster and push away sample, sample is not understood outer spattering, and passage can not stopped up fully, is convenient to realize robotization, the mould of making this utility model is simple, semi-manufacture are easy to assembly, can large-scale production, and production cost is low, can disposablely use, stop cross pollution.
