Description

Simple pipettor for clinical laboratory

Technical Field

The utility model relates to a pipettor especially relates to clinical laboratory uses simple and easy pipettor.

Background

The liquid-transfering gun is a metering tool for transferring liquid from original container to another container in a certain range, and is widely used in transfer or titration process of test sample agent in hospital clinical laboratory. The general pipettor has higher purchase cost, cannot be prepared in large batches, and in order to save practical cost, a part of the pipettors can be directly titrated by using disposable syringes, but if the disposable syringes use needles, the test sample agent is difficult to be titrated by quantitative liquid drops, and if the needles are pulled out for titration, the pipettors are easy to be titrated excessively, and the operation is very difficult.

SUMMERY OF THE UTILITY MODEL

The utility model provides a clinical laboratory is with simple and easy pipettor has solved and has now directly titrated with disposable syringe, but disposable syringe if used syringe needle inspection appearance agent hardly with quantitative liquid drop dropping, if pull out the syringe needle and titrate, titrate excessively, operates very difficult problem again very easily.

In order to solve the technical problem, the utility model provides a following technical scheme:

the utility model provides a clinical laboratory uses simple and easy pipettor, including the pipette, pipette one end fixed connection feed liquor pipe, feed liquor pipe size is less than the pipette size, the inside piston that is equipped with of pipette, piston one end fixed connection push rod, push rod one end is passed the through-hole and is located the pipette outside, the cover is equipped with the fender ring on the push rod terminal surface, it is equipped with the answer spring to keep off between ring and the inside top of pipette, the pipette inner wall is equipped with down keeps off the ring, keep off ring sliding connection spout down, the spout sets up on the pipette inner wall, keep off ring top fixed connection down and adjust the pole, it removes the hole to adjust pole swing joint, it communicates with each other with the spout to remove the downthehole portion, removes the hole top and is located the pipette top.

Preferably, the inner part of the moving hole is provided with an internal thread, and the outer wall of the adjusting rod is provided with an external thread. Through setting up inside and outside screw thread, accessible rotary motion adjusts the pole, and then makes the regulation pole reciprocate, drives down the fender ring and reciprocates.

Preferably, the lower part of the inner wall of the liquid inlet pipe is obliquely arranged, and the size of the bottom of the liquid inlet pipe is smaller than the sizes of other parts of the liquid inlet pipe. The liquid inlet pipe is obliquely arranged, so that the bottom flow velocity is increased conveniently.

Preferably, the top of the adjusting rod is sleeved with an adjusting cylinder with scales. Through setting up the regulation section of thick bamboo that has the scale, but convenient to use person adjusts.

Preferably, the top of the push rod is provided with a propelling cylinder, the top of the liquid inlet pipe is provided with a through hole, the through hole is connected with the propelling cylinder in a sliding mode, and the pressure of a user is relieved when the user adjusts the propelling cylinder.

Through the technical scheme, the utility model discloses beneficial effect: through setting up the lower fender ring of adjusting the pole and can removing, through adjusting the position of keeping off the ring down, and then the feed liquor volume of control feed liquor pipe, and the utility model discloses for the liquid-transfering gun of specialty, the cost is comparatively cheap, is fit for using on a large scale.
