Abstract
The utility model relates to a multishift liquid-transfer device, which is suitable for testing in the departments of school chemical engineering, scientific research, etc. and sampling and adding micro liquids of blood, etc. in biochemical assays. The utility model is characterized in that the utility model comprises a disposable liquid storing tube 1 arranged on the left end of an outer shell 2 of a liquid storing device; a liquid-transfer handle bar 3 sheathed with a reset spring 4 is arranged on the right end of the outer shell 2 of a liquid-transfer device; a support bracket 8 is sheathed in the outer shell 2 of the liquid-transfer device; a thorn rod 6 and a spring 7 are arranged on the support bracket 8; a reset button 5 is arranged on one end of the thorn rod 6; the liquid-transfer handle bar 3 is provided with a clamping groove 9. The product has the advantages of simple structure, convenient operation, low labor intensity and time saving. The accuracy rate of the testing result is 100 percents.
Description
The utility model relates to a kind of pipettor that measures accurate measuring device, particularly a kind of many gears of formula, and it is applicable to school's chemical industry, makes the sampling and the liquid feeding of micro liquids such as blood in the chemical examination of departments such as scientific research and the biochemical analysis.
At present a lot of laboratories have all adopted micropipettor in technical operating procedure, thereby the glass pipette and the rubber bulb pump of usefulness have in the past been substituted, make test procedure reach simple and rapid purpose, reduced the application of sample error, this micropipettor can only once quantitatively suck and discharge.We feel to use as one wishes not to the utmost in actual application.For example, when doing the test of five indexes of hepatitis b enzyme labeling thing, each sample need repeat five times and suck, and moves into respectively in the test cup of five different test items again.Time-consuming, effort operates.Product sold has the WKY-50 micropipettor on the market, and it is to utilize the displacement principle, makes to decide Cheng Yundong by piston in piston bush and produces negative pressure, suck quantitative liquid earlier, property discharge quantitative liquid when for example doing the five indexes of hepatitis b check, will repeat 5 times and suck, discharges again.This product uses inconvenient, and giving accurately, check has brought certain difficulty.
The purpose of this utility model is at above deficiency and the pipettor of improved a kind of many gears, it is to have increased many grades of pumping equipments on existing pipettor, it can be put at many gears and move, it can once suck quantitative liquid, can discharge quantitative liquid continuously again, improve the degree of accuracy of check.
The utility model is achieved in that the pipettor of many gears comprises the disposable liquid storage pipe 1 of reservoir shell 2 left ends dress, the liquid removing handle lever 3 that is set with back-moving spring 4 is contained in the right-hand member of pipettor shell 2, wherein, support 8 is sleeved in the pipettor shell 2, sour jujube bar 6 and spring 7 are contained on the support 8, SR 5 is contained in an end of sour jujube bar 6, and draw-in groove 9 is arranged on the liquid removing handle lever 3.
The good effect of utility model is:
1, this product has improved efficiency of test, and the accuracy rate of its assay is 100%.
2, this product structure is simple, and is easy to use, and it had both alleviated labour intensity, had saved the time again, reached quick, and convenient, practical purpose is simultaneously for making things convenient for patient that assurance is provided.
Description of drawings.
Fig. 1 is a profile schematic diagram of the present utility model.
Fig. 2 is a structure cutaway view of the present utility model.
Fig. 3 is the A portion enlarged drawing of the utility model Fig. 2.
Wherein
1, disposable liquid storage pipe 2, pipettor shell 3, liquid removing handle lever 4, back-moving spring
5, SR 6, sour jujube bar 7, spring 8, support 9, draw-in groove
The utility model is described in further detail below in conjunction with accompanying drawing.
As Fig. 1,2,3, shown in.The utility model is to have increased many grades of pumping equipments on existing pipettor, the formation of this device be in pipettor shell 2 suit support 8, sour jujube bar 6 is fixed on the support 8, and draw-in groove 9 is arranged on liquid removing handle lever 3, SR 5 is contained in an end of sour jujube bar 6.When getting liquid, press SR 5, press liquid removing handle lever 3 simultaneously to left end, loosen liquid removing handle lever 3 again, reset under the effect of back-moving spring 4, sour jujube bar 6 snaps into the left end of draw-in groove 9, finishes and gets the liquid function.Loosen SR 5 then, the pipettor of many gears enters and moves liquid status, can quantitatively draw 250 microlitre liquid in the disposable reservoir 1.When discharging liquid, press liquid removing handle lever 3, whenever by a liquid removing handle lever 3, sour jujube bar 6 is under the effect of spring 7, and the draw-in groove 9 to the right moves a draw-in groove.Whenever press liquid removing handle lever 3 once, sour jujube bar 6 moves a draw-in groove 9, can move liquid 50 microlitres.Whenever get liquid once, can move liquid continuously 5 times, thereby realized the time can once drawing sample doing check, distinguish continuous 5 times again sample added in the test cup.Do a five indexes of hepatitis b test (as calculating by 48 person-portions) with the WKY-50 pipettor, the whole operation process need be 90 minutes with the time; If do above-mentioned same test with the multidigit pipettor after improving, the used time is 60 minutes.Its result's the degree of accuracy is 100%.So both alleviated labour intensity, saved the time again, provided assurance for making things convenient for patient.
