Utility model content
The purpose of this utility model is to disclose a kind of minim suction dropper, solves the problem that existing dropper accurately cannot draw quantitative micro liquid reagent, solves processing cost further high, holds breakable problem in transport, storage.
For achieving the above object, the utility model adopts following technical scheme:
A kind of minim suction dropper, comprises at least two bladders of receiving fluids, suction pipe and flow duct; At least two bladders connect successively, and suction pipe comprises draws most advanced and sophisticated and pipetting tips, and pipetting tips is communicated with first bladder, is communicated with between adjacent bladder by flow duct; The volume of each bladder is identical.
Further, the volume of described bladder is 1 milliliter.
Further, the brace for being fixedly connected with is provided with between adjacent bladder.
Further, described suction pipe and described flow duct are interspersed.
Further, when the quantity of described bladder is more than or equal to three, adjacent described flow duct is interspersed.
Further, described bladder, described suction pipe and described flow duct are for adopting the integrated plastic construction of Shooting Technique.
Further, described absorption is most advanced and sophisticated tapered, and diameter reduces gradually from inside to outside.
Further, the wall thickness of described bladder is 0.1mm ~ 0.3mm, and the wall thickness of described suction pipe is 0.4mm ~ 1mm.
Further, described bladder quantity is 3, is divided into first bladder, second bladder and the 3rd bladder; The pipetting tips of described suction pipe connects first bladder, is communicated with between first bladder and second bladder by described flow duct; Be communicated with by flow duct between second bladder and the 3rd bladder.
Further, described pipetting tips is communicated with the right side of described first bladder, and the left side of first bladder is communicated with the described flow duct that passes on left of described second bladder; The right side of second bladder is communicated with by flow duct with the right side of described 3rd bladder.
Compared with prior art, the beneficial effects of the utility model:
1, the utility model adopts at least two bladder structures, due to each bladder have Stationary liquid with volume, convenient operation person controls the liquid capacity of absorptions, drippage, improves the precision of the quantitative micro liquid reagent of absorption.Adjacent flow duct is interspersed, and suction pipe and flow duct are interspersed, and ensure that previous bladder will be full of liquid, next bladder just has liquid and flows to
2, dropper is made of plastic owing to adopting, and can adopt Shooting Technique machine-shaping, and the cost of raw material and processing cost are all very low; In transport and storage, can not be damaged by pressure, convenient and practical.
Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
Fig. 1 is the front elevational schematic of this practical a kind of minim suction dropper embodiment;
Fig. 2 is that schematic diagram is looked on a left side of Fig. 1;
In figure, 1-bladder; 11-first bladder; 12-second bladder; 13-the 3rd bladder; 2-suction pipe; 21-draws tip; 22-pipetting tips; 3-flow duct; 4-brace.
Detailed description of the invention
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technical scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
A kind of minim suction dropper of embodiment as depicted in figs. 1 and 2, comprises at least two bladders 1 of receiving fluids, suction pipe 2 and flow duct 3; At least two bladders 1 connect successively, and suction pipe 2 comprises draws most advanced and sophisticated 21 and pipetting tips 22, and pipetting tips 22 connects first bladder 11, is communicated with between the adjacent bladder of at least two bladders by flow duct 3.The volume of each bladder is identical, is 1 milliliter, is convenient to the amount controlling institute's imbitition.The utility model adopts at least two bladder structures, and because each bladder has fixing volume, convenient operation person controls the liquid capacity of absorption, drippage, improves the precision drawing quantitative micro liquid reagent.Being provided with the brace 4 for being fixedly connected with between adjacent bladder, being convenient to the fixing of bladder.Adjacent flow duct 3 is interspersed, and suction pipe 2 and flow duct 3 are interspersed, and ensure that previous bladder will be full of liquid, next bladder just has liquid and flows to.The volume of each bladder increasing or decreasing connection successively at least two bladders 2.
The bladder quantity of the present embodiment be 3 (but be not limited to 3, can be 2,4 etc.), be divided into first bladder, 11, second bladder 12 and the 3rd bladder 13.Pipetting tips 22 is communicated with the right side of first bladder 11, and the left side of first bladder 11 is communicated with the flow duct 3 that passes on left of second bladder 12; The right side of second bladder 12 is communicated with by flow duct with the right side of the 3rd bladder 13.
Bladder 1, suction pipe 2 and flow duct 3 adopt the integrated plastic construction of Shooting Technique, and the cost of raw material and processing cost are all very low; In transport and storage, can not be damaged by pressure, convenient and practical.Draw tip 21 tapered, diameter reduces gradually from inside to outside.The wall thickness of bladder 1 is 0.1mm ~ 0.3mm, and the wall thickness of suction pipe 2 is 0.4mm ~ 1mm.
As further illustrating the present embodiment, its workflow is now described: presses against bladder thing 1, liquid enters suction pipe 2 from absorption most advanced and sophisticated 21, then enters first bladder 11 from pipetting tips; When first bladder 11 is from full liquid, liquid enters second bladder 12 through flow duct 3; When second bladder 12 is from full liquid, liquid enters the 3rd bladder 13 through flow duct 3.
