Abstract
The utility model relates to a quantitative filling injector, which comprises a reagent bottle which is separated by a baffle, and a syringe pipe with an upper piston pipe and a lower piston pipe which is located on the upper portion of the reagent bottle. The upper piston pipe is connected with an outlet pipe, the lower piston pipe is connected with two ducts which are inserted in the reagent bottle, the upper end of the syringe pipe is fixed on a handle knob, and the lower end of the syringe pipe is connected with a bottle cork. A filter screen is fixed in the inner portion of the syringe pipe, a differentiator which has an end face with evenly divided scales is fixed on the lateral side of the syringe pipe, the bottleneck of the reagent bottle and the bottle cork are provided with threads, and the bottleneck of the reagent bottle and the bottle cork are connected through a female screw. The utility model is provided with a differentiator which can acutely take reagents and reduce mistakes. The utility model has the advantages of simple structure, convenient manufacture and employment, low cost, which is suitable to be popularized and applied.
Description
(1) technical field
This utility model relates to a kind of medical apparatus and instruments, and particularly a kind of each hospital laboratory and other laboratorys of being used for faces with the continuous liquid feeding of the reagent of preceding mixing in proportion to several need or be used for the quantitative charger of mix reagent.
(2) background technology
At present, " the adjustable quantitative charger " that Qiujing Glass Instrument Factory, Shanghai produces has been widely used in the continuous liquid feeding of each hospital laboratory and other laboratory all ingredients, adding reagent with craft with suction pipe compares, have conveniently, reliable, repetitive error is little, advantage such as save time, but this product has limitation: every " adjustable quantitative charger " can only contain a kind of reagent and to the continuous liquid feeding of this kind reagent.In many experiments, appoint several reagent are added in each reaction tube more quantitatively facing with after before being mixed in proportion.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 the mixing such as reagent 1 and 11, convenient for adding reagent, it is reagent 1 and reagent 11 to be poured in one " adjustable quantitative charger " separately successively two kinds of reagent are made continuous liquid feeding again that part hospital has also used " adjustable quantitative charger " method, its weak point is: do not undertaken by rule of operation, 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 after reagent I and 11 amalgamations in one " adjustable quantitative charger ", its shortcoming is: need face with preceding mixing pretty troublesomely, shelving for a long time with surplus mix reagent can not reuse, causes waste; Get used in amounts in addition by visual, have error marking inconvenience.
(3) summary of the invention
This utility model provides a kind of convenient and practical quantitative charger in order to overcome the deficiency of above technology.
This utility model is realized by following measure: a kind of quantitative charger, comprise the reagent bottle that is separated by dividing plate, be positioned at the syringe tube that has upper piston pipe and lower piston pipe of reagent bottleneck top, described upper piston pipe links to each other with outlet, the lower piston pipe links to each other with two conduits in the insertion reagent bottle, described syringe tube upper end be fixed on one handle knob on, the syringe tube lower end links to each other with bottle stopper, the syringe tube internal fixation has a drainage screen, the syringe tube side is fixed with a differentiator that has an evenly divided end face, reagent bottleneck and bottle cap are done external screw thread, and reagent bottleneck and bottle cap link together by nut.
The beneficial effects of the utility model: be provided with differentiator, can accurately get reagent, reduce error, simple in structure, make easy to use, with low cost, suitable applying.
(4) description of drawings
Below in conjunction with the drawings and specific embodiments this utility model is described in further detail.
Fig. 1 concrete structure sketch map of the present utility model.
1. outlets are 2. handled knob among the figure, 3. differentiator, 4. lower piston pipe, 5. conduit, 6. dividing plate, 7. nut, 8. drainage screen, 9. upper piston pipe, 10. syringe tube.
(5) specific embodiment
A kind of as shown in Figure 1 quantitative charger, comprise the reagent bottle that is separated by dividing plate 6, be positioned at the syringe tube 10 that has upper piston pipe 9 and lower piston pipe 4 of reagent bottleneck top, described upper piston pipe 9 links to each other with outlet 1, lower piston pipe 4 links to each other with two conduits 5 in the insertion reagent bottle, described syringe tube 10 upper ends are fixed on one and handle knob on 2, syringe tube 10 lower ends link to each other with bottle stopper, syringe tube 10 internal fixation have a drainage screen 8, syringe tube 10 sides are fixed with a differentiator 3 that has an evenly divided end face, reagent bottleneck and bottle cap are done external screw thread, and reagent bottleneck and bottle cap link together by nut 7.
Described differentiator 3 can accurately be got reagent, reduces error.
During use, whenever lash once and can draw two kinds of different reagent equally, mix the back and penetrate from outlet 1.
