Abstract
The utility model relates to a quantitative transfer pipe, which includes a transfer pipe, wherein a quantitative device is mounted at the upper end of the transfer pipe, and includes a piston cylinder, as well as a piston and a connecting rod both arranged inside the piston cylinder; the piston cylinder is fixed and communicated with the transfer pipe; the piston is fixed with the connecting rod; a reset spring is arranged between the piston and the cylinder bottom of the piston cylinder; scale values and an adjusting nut are arranged on the connecting rod. As the quantitative device is arranged in the quantitative transfer pipe, after liquid is transferred, the liquid transfer value can be set through the adjusting nut, thereby being more accurate, and test error can be reduced; when the quantitative transfer pipe is used for testing, especially when a test requiring large amount of transferred liquid is carried out, the quantitative transfer pipe can be used for transferring liquid, is easy and saves force, solves the problem that the testing time is prolonged as the liquid quantity requires fine adjustment, has a simple structure, is simple and convenient to operate and strong in practicability, and is suitable for being popularized and applied in test rooms related to medical tests in hospitals, research laboratories, colleges, universities, and the like.
Description
Technical field
The medical test instrument that the utility model relates to, what be specifically related to is a kind of quantitative pipette.
Background technology
At present, the pipette of experiment usefulness mostly is the straight tube glass tube of up/down perforation, during use, need to insert pipette upper end mouth of pipe imbitition by rubber pipette bulb, by the pipe inner and outer air pressure poor purpose that reaches imbitition, when the amount of taking of liquid is enough, remove rubber pipette bulb, block the mouth of pipe with forefinger, and reach regulating liquid surface height purpose by slow moveable finger or pipette.The problem of the test inconvenience that exists in the time of can remedying without the wide range liquid-transfering gun but go back Shortcomings in the use procedure is: use pipette to cooperate with finger and get liquid, operation inconvenience; Secondly, it is wayward to get liquid measure, poor as moving away at rubber pipette bulb with life period in the process blocked of finger, liquid in the pipe can descend, liquid level is fallen under the required scale easily, causes moving the liquid failure, and the fine setting of liquid level is slight mobile realization of pointing, the difficult control of liquid level needs skilled operating technology.Therefore, can't move fast and accurately liquid, so not only prolong test period, also make the accuracy of result of the test be subject to impact, waste unnecessary man power and material.We are badly in need of a kind of wide range pipette that can be quantitative, time saving and energy saving, easy to use for this reason.
The utility model content
Goal of the invention of the present utility model is to provide a kind of quantitative pipette for the problems referred to above, is used for solving the pipette existence of using at present and is difficult for accurately making the problem of moving the liquid measure journey.
The utility model is achieved through the following technical solutions: quantitatively pipette comprises pipette, and described pipette upper end is equipped with proportioning device; Piston and connecting rod that described proportioning device comprises piston cylinder and is positioned at piston cylinder inside, piston cylinder is fixed with pipette and is communicated with, piston and connecting rod are fixed, and are provided with back-moving spring between at the bottom of piston and the piston cylinder cylinder, are provided with scale value and adjusting nut on the connecting rod.
As further improvement of the utility model, described piston cylinder is set with outward to control holds cover.
Adopt the good effect of technique scheme:
1, be provided with proportioning device in the utility model, get liquid after, can set by adjusting nut and move the liquid value, make that to move liquid measure more accurate, reduce the error of test;
2, the utility model in test especially needs to move in enormous quantities the test of liquid, but rapid moving liquid, and the save trouble and labor has been avoided prolonging the problem of test period because of the fine setting amount of liquid;
3, simple in structure, the simple operation, practical of the utility model is adapted at the medical experiment correlation test chambers such as hospital, research institute, colleges and universities and promotes the use of.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Among the figure: 1 pipette, 2 piston cylinders, 3 pistons, 4 connecting rods, 5 back-moving springs, 6 adjusting nuts, 7 control and hold cover.
The specific embodiment
Below in conjunction with concrete diagram, the utility model is further set forth.
As shown in Figure 1, quantitatively pipette comprises pipette 1, and improvements of the present utility model are: pipette 1 upper end is equipped with proportioning device.The purpose that proportioning device is set is, after liquid is inhaled into pipette, accurately make need move the liquid value, make that to move liquid measure more accurate, reduce the error of test.
In the utility model, piston 3 and connecting rod 4 that proportioning device comprises piston cylinder 2 and is positioned at piston cylinder 2 inside.Wherein, piston cylinder 2 is fixed with pipette 1 and is communicated with.Piston 3 is fixing with connecting rod 4, is provided with back-moving spring 5 between at the bottom of 2 of piston 3 and the piston cylinders, and under the effect of back-moving spring 5 elastic force, piston 3 can move up and down in piston cylinder 2.Be provided with scale value and adjusting nut 6 on the connecting rod 4.
On the basis of above-mentioned technical scheme, for further increasing the comfortableness of operation, also can control at piston cylinder 2 outer suits and hold cover 7.Control and hold cover 7 and can select the preparation of the softwood matter such as rubber.
During use, at first adjusting nut is adjusted to top, pipette is inserted under the liquid level of the liquid of getting, after liquid is inhaled into pipette, again pipette is taken out from liquid, then, by setting adjusting nut, to required scale value of moving liquid measure, afterwards, press connecting rod, liquid is accurately moved in the required container.Simple in structure, the simple operation of the utility model especially needs to move in enormous quantities the test of liquid, and it is more outstanding to move the liquid effect, the save trouble and labor.
