Abstract
The utility model discloses a continuous metering suction unit for a pipette, which comprises a liquid storage bottle 1, a liquid storage bottle cover 2 and a pipette 3, and is characterized in that a through hole 4 is formed in the middle of the liquid storage bottle cover 2, a suction unit 5 is arranged above the liquid storage bottle cover 2, and a liquid feeding one-way valve 6 and a drainage tube 7 are arranged below the liquid storage bottle cover 2; the pipette 3 is connected with a liquid outlet one-way valve 5e of the suction unit 5; the liquid storage bottle 1 adopts transparent plastic material; scales 8 are arranged on the bottle body of the liquid storage bottle 1; and a sucking disc 9 is stuck at the bottom part of the bottle body. The continuous metering suction unit for a pipette has the advantages of continuous suction, convenient operation and time and labor conservation, and further, no remaining liquid, accurate metering, higher examination rate and better effect.
Description
Technical field
The utility model relates to a kind of assay device, specifically a kind of liquid continuous metering aspirator that moves.
Background technology
Hospital laboratory, the breadboard liquid method of moving generally adopt common pipette at present, and the pipette of usefulness is a glass tube that has scale now, during use, connects a Liquid absorption ball in the end and uses.This liquid method of moving, though existing extensive use also has weak point: the one, the project big to the need liquid measure, Liquid absorption ball can not continuous sucking liquid, and operation is wasted time and energy, especially to chemistry reflection chemical examination faster, affect course of reaction easily adversely, cause the chemical examination failure sometimes; The 2nd, easy made allowance has aspirated often in the pipette, also can influence result of laboratory test.
Summary of the invention
The purpose of this utility model is to provide a kind of continuous sucking, and is easy to operate, time saving and energy saving, made allowance not, and accurate measurement, that can improve chemical examination speed and effect moves liquid continuous metering aspirator.
For reaching above purpose, technical solution adopted in the utility model is: this moves liquid continuous metering aspirator, constitute by liquid storage bottle, liquid storage bottle cap, pipette, it is characterized in that establishing through hole in the centre of liquid storage bottle cap, aspirator is established in the top, and feed liquor check valve and catheter are established in the below, pipette is connected with the fluid check valve of aspirator, liquid storage bottle is that transparent plastic is made, and establishes scale on the bottle of liquid storage bottle, sucker on bottle body bottom is pasted.The utility model is also implemented by following measure: described aspirator, constitute by suction cylinder, piston, piston rod, piston rod handle, fluid check valve, suction cylinder is connected with the liquid storage bottle cap, piston rod one end is connected with piston, the other end and piston rod handle join, piston stretches in the piston cylinder, and the fluid check valve is located at lower end wall one side of suction cylinder.When using the utility model, open the liquid storage bottle cap, liquid is injected in the liquid storage bottle, with sucker liquid storage bottle is fixed on the medical table, the medical worker pulls the piston rod handle, the fluid closed check valve, and the feed liquor check valve is opened, liquid enters in the suction cylinder, instantly during push piston bar handle, the feed liquor closed check valve, the fluid check valve is opened, liquid just flows in the pipette, reciprocating sliding piston rod handle, liquid be outflow continuously just, when the scale of observing on the liquid storage bottle bottle, during the amount of satisfying the demand, stop to promote the piston handle.
The use the beneficial effects of the utility model are: compare with the present liquid method of moving, not only have continuous sucking, and easy to operate, time saving and energy saving function, but also have not made allowance, accurate measurement can improve the advantage of chemical examination speed and effect.
