Abstract
The utility model provides a kind of rubber head dropper that can draw plurality of reagents.The rubber head dropper is equipped with Capsule at the top of tube body, card slot and lower bayonet slot are had on tube body, dropper is housed in tube body, the outside of dropper is cased with spring, it manages and band driving lever sliding block is housed in vivo upper card slot, equipped with suction pipe among band driving lever sliding block, the both ends of suction pipe are connected respectively with dropper and Capsule.The rubber head dropper can be used for drawing different reagents, easy to use in the case where being not easy to replace rubber head dropper for unconditional cleaning rubber head dropper in time during field sampling, and without carrying more rubber head droppers each time.
Description
Technical field
The utility model is related to arrive experiment equipment field, a kind of rubber head dropper that can draw plurality of reagents is related specifically to.
Background technology
In biology and chemical experiment, rubber head dropper is indispensable, and frequency of use is high.Rubber head dropper is by Capsule and glass
Glass pipe forms, for drawing or being added dropwise a small amount of liquid reagent.Now exemplified by preserving fry sample, the fry sample that collects in the wild
This, routinely needs to carry out Morphological Identification and Molecular Identification, it is necessary to be retained separately to sample, in the sample of Morphological Identification
Formalin test solution is added, alcohol is added in the sample of Molecular Identification, will use arrive rubber head dropper at this time, which mainly uses
In the addition of reagent.
Provide in an experiment rubber head dropper can not cross-reference, cleaned immediately with distilled water after being finished, forbid not clean
With regard to drawing another reagent.In experiment sample acquisition in the wild, plurality of reagents is frequently necessary to the sample of different experiments purpose
Classification preserves, and causes cleaning not in time because field sampling process lacks distilled water, a sampling process usually requires to carry more
Rubber head dropper, and need to label and distinguish.It is relatively inconvenient at more that this traditional rubber head dropper once carries, and uses
Middle replace takes, complex for operation step.In order to solve these troubles, so being badly in need of that plurality of reagents can be drawn in once testing
And will not cross contamination rubber head dropper.
The content of the invention
The purpose of this utility model is to provide a kind of glue that can draw plurality of reagents equipped with more droppers in tube body
Head dropper.
To achieve the above object, the technical solution of the utility model is：
A kind of rubber head dropper that can draw plurality of reagents, including Capsule, tube body, band driving lever sliding block, upper card slot, lower bayonet slot,
Dropper, spring and suction pipe, the rubber head dropper are equipped with Capsule at the top of tube body, card slot and lower card are had on tube body
Slot, tube body is interior equipped with dropper, and the outside of dropper is cased with spring, manages and band driving lever sliding block is housed in vivo upper card slot, slided with driving lever
Equipped with suction pipe among block, the both ends of suction pipe are connected respectively with dropper and Capsule.
2-8 root droppers are housed in the tube body.
The Capsule outputs corresponding passage according to the quantity of filled suction pipe.
The good effect of the utility model is：
1st, the rubber head dropper can be used for drawing different reagents, for the unconditional rubber head drop of cleaning in time during field sampling
Pipe, it is easy to use in the case where being not easy to replace rubber head dropper, and without carrying more rubber head droppers each time；
2nd, the rubber head dropper can be distinguished effectively by the color of driving lever button draws the corresponding dropper of reagent, prevents
The maloperation of cross-reference phenomenon generates；
3rd, the rubber head dropper can develop into multiple droppers on the basis of 2 droppers, a variety of of different nature for drawing
Reagent has very big development potentiality；
4th, the rubber head dropper is relatively easy, and deft design, easy to operate change, suit large area to popularize application.
Description of the drawings
Fig. 1, the rubber head dropper structure diagram that plurality of reagents can be drawn；
Fig. 2, the slide block structure schematic diagram with driving lever.
Specific embodiment
Clear, complete description is further carried out to the technical solution of the utility model below in conjunction with the accompanying drawings.
Referring to attached drawing 1-2, when in use, press one of band driving lever sliding block 3, make band driving lever sliding block 3 from upper card slot 4 into
Enter into lower bayonet slot 5, band driving lever sliding block 3 is moved downward along suction pipe 8, while dropper 6 is released tube body 2 with driving lever sliding block 3, at this time
The spring 7 being sleeved on dropper 6 is compressed, and squeezes the Capsule 1 being connected with suction pipe 8, and unclamping Capsule 1 will be tried by the negative pressure of generation
Agent is drawn into dropper 6 and suction pipe 8, is squeezed Capsule 1 again, is oozed the reagent in dropper 6 and suction pipe 8 by pressure.It uses
After complete, band driving lever sliding block 3 is stirred again, under the elastic force effect of spring 7, it is made to be returned to from lower bayonet slot 5 in upper card slot 4, together
When drive dropper 6 return in tube body 2.When needing that different liquids are added dropwise, another band driving lever sliding block 3 is replaced, is repeated above-mentioned
Step.
