Abstract

The utility model relates to a multifunctional quantitative liquid feeder which is used for clinical laboratories all hospitals and other laboratories. A reagent bottle is divided into a plurality of parts by separation sheets. The upper part of a mouth of the reagent bottle is provided with a pair of common injectors with an upper and a lower piston pipes, wherein, the upper piston pipe is connected with an outlet pipe, and the lower piston pipe is connected with a plurality of catheters of each part which extends into the reagent bottle. The piston pipes can be made of glass, plastics, etc. The utility model has the advantages that a plurality of kinds of reagents are sucked once, after the reagents are mixed, the reagents are ejected out of an identical outlet pipe, and consequently, the workload of inspection personnel can be reduced.

Description

Multi-functional quantitative liquid feeder

The utility model is mainly used in each hospital laboratory and other laboratories several need is faced continuous liquid feeding with the reagent of preceding mixing in proportion, or is used for mix reagent.

" the adjustable quantitative charger " of Qiujing Glass Instrument Factory, Shanghai's production at present has been widely used in the continuous liquid feeding of each hospital laboratory and other laboratory all ingredients, compare with former manual method (adding reagent with suction pipe by hand), have conveniently, reliable, repetitive error is little, save time and advantage such as province's expense, but using, this product have limitation, promptly every " adjustable quantitative charger " can only contain a kind of reagent and to the continuous liquid feeding of this kind reagent.In many experiments, often need several reagent are added in each reaction tube after the mixing in proportion more quantitatively facing with preceding.Often do the mensuration of project calcium, magnesium ion and flesh liver as visiting, its operation all is to be added in each reaction tube more quantitatively after reagent I and the II mixed in equal amounts, convenient for adding reagent, part hospital has also used " adjustable quantitative charger ", method is that reagent I and reagent II are poured in one " adjustable quantitative charger " separately, successively two kinds of reagent are made continuous liquid feeding again, its shortcoming is: do not undertaken by operational procedure, error is big; Need to do twice and add reagent, trouble, time-consuming.Other method is: face with preceding and carry out continuous liquid feeding pouring into behind reagent I and the II mixing in one " adjustable quantitative charger ", its shortcoming is: need face and use preceding mixing, and pretty troublesome, shelved for a long time and can not use again with surplus mix reagent, cause waste.For solving these problems that exist in the real work, the utility model people reequips former " adjustable quantitative charger ", has designed the utility model.

The utility model has the advantages that: a secondary syringe only is installed in its structure, just can implement the continuous liquid feeding of several agents, and can be automatically mix reagent in proportion, a secondary syringe can only carry out the limitation that covering of continuous liquid feeding held and reality is used to a kind of reagent in former " adjustable quantitative charger " thereby overcome, and plays a multiplier role.

Main purpose of the present utility model is to add the reagent instrument for what each clinical labororatory provided convenience in some experiments.Another purpose is for producer provides manufacture method of the present utility model, and existing is example with the accompanying drawing, is explained in detail with regard to its structure and use etc.

As shown in drawings: reagent bottle is divided into not connected two parts by partition 6; the syringe 2 of configuration one subband upper piston pipe 9 and lower piston pipe 4 above the reagent bottleneck; wherein upper piston pipe 9 links to each other with outlet 8; lower piston pipe 4 links to each other with two conduits 5 that stretch into the reagent bottle both sides respectively; the lower end of syringe 2 is inserted bottle stopper and is made it fixing; bottle stopper and reagent bottle are by nut 10 further fixing (also available plastics etc. are made an overcoat, with protection, fixedly syringe and effect such as attractive in appearance).Piston upper end can be fixed on handles knob on 7, handle knob 7 to link to each other with backstay 1, by regulate positioning sleeve 3 decide add amount of reagent.In use two kinds of different reagent are poured into the both sides of reagent bottle respectively, after putting parts such as bottle stopper and syringe well, fastening nut 10, under identical situation such as the character of two kinds of reagent and the internal diameter of conduit 5, because the special construction of piston tube up and down, can draw two kinds of different reagent equally so whenever lash shot device core, mix the back and penetrate from outlet 8.

The utility model is divided into the reagent bottle of fractional part, can be to be separated by partition, can be that fractional part container and closing forms, and can be to put into 1 to several little reagent bottles to constitute in a big reagent bottle.Each several part feeds a conduit respectively, and the internal diameter size of conduit is decided according to the requirement of liquid volume added and the character that added reagent.Upper and lower piston tube and syringe can be installed in the reagent bottle or reagent bottle outside, the lower piston pipe can be installed in the conduit, the syringe of piston tube constitutes about also can having separately by number is secondary, wherein the upper piston pipe links to each other with same outlet, and the conduit that the lower piston pipe is connected separately stretches into reagent to be added respectively; Also can be that the number pairs only have the lower piston pipe separately, and the conduit of lower piston Guan Suolian stretches into reagent to be added respectively, upper piston pipe and outlet be shared syringe and constitute.

Claims
