Abstract
The utility model discloses an accurate liquid taking device once, including burette and spherical reservoir, the reservoir is the casing under the hemispherical who lies in the below, and lies in the hemispherical atmospheric pressure of casing top is pressed the button down, the lower extreme of casing is provided with the through -hole down, is provided with gland nut in the through -hole, be provided with the external screw thread on the lateral wall on the upper portion of burette, the burette spiro union in gland nut is last, and at least, some enters into the burette in the reservoir. The present invention uses the technical scheme, the utility model discloses an accurate liquid taking device once can guarantee to instil into the accuracy of reagent liquid, the burette can be changed as required to in the time need clearing up the reagent liquid in the reservoir, only need lift the burette off, can discharge reagent liquid.
Description
Technical field
This utility model is related to an a kind of accurate liquid extracting device, belongs to precision chemical instrument and equipment technical field.
Background technology
In pharmaceutical technology field, often carry out antibody detection test, antibody test unit is instilled on strip, then observes
Strip changes.But in this process of the test, often occur when antibody test unit is dropped in strip instilling excessive or mistake
Few situation is so that the detection agent in strip cannot cause test error excessive in an accurate scope of data.
Utility model content
Therefore, the purpose of this utility model is to overcome defect of the prior art, provides one kind can accurately instill anti-
An accurate liquid extracting device of first reagent solution is surveyed in health check-up.
To achieve these goals, an a kind of accurate liquid extracting device of the present utility model, including dropper and spherical storage
Liquid device；Described reservoir includes underlying hemispheric lower house, and is located at hemispheric above described lower house
Air pressure button；The lower end of lower house is provided with through hole, is provided with sealing nut, on the lateral wall on the top of described dropper in through hole
It is provided with external screw thread, described dropper is bolted on described sealing nut, and described dropper at least a portion enters into described storage
In liquid device.
The lower surface of described dropper is obliquely installed.
The length of the male thread portion of described dropper is at least 1/3rd of described dropper length.
Described lower house is plastic material, and described air pressure button is quality of rubber materials.
Using technique scheme, an accurate liquid extracting device of the present utility model, during use, it is located at reservoir with thumb pressure
The air pressure button on top, after discharge part air inserts dropper in reagent solution, unclamps thumb, reagent solution can suck dropper and go forward side by side
Enter in reservoir, generally, we install required dropper on transfusion device, and the internal volume of dropper is constant, so,
The reagent solution of the volume required for storing in dropper, unnecessary reagent solution can enter in reservoir, therefore when continuation is to strip
When instilling reagent solution, the reagent solution in reservoir will not again flow into determines liquid pipe, thus only by quasi- for the reagent solution in dropper ground
Drip in strip it is ensured that instilling the accuracy of reagent solution；Dropper can be changed as needed, and is needing liquid storage
It is only necessary to unload dropper when reagent solution in device is cleared up, you can discharge reagent solution.
Brief description
Fig. 1 is structural representation of the present utility model.
Specific embodiment
Below by way of the drawings and specific embodiments, the utility model is described in further detail.
As illustrated, the present embodiment provides an accurate liquid extracting device, including dropper 2 and spherical reservoir 1；Described storage
Liquid device 1 includes underlying hemispheric lower house 11, and the hemispheric air pressure being located above described lower house 11 is pressed
Button 12；The lower end of lower house 11 is provided with through hole, is provided with sealing nut 111, the lateral wall on the top of described dropper 2 in through hole
On be provided with external screw thread 21, described dropper 2 is bolted on described sealing nut 111, and described dropper 2 at least a portion enters
To in described reservoir 1.
The lower surface of described dropper 2 is obliquely installed.
The length of the external screw thread 21 of described dropper 2 is at least 1/3rd of described dropper 2 length.
Described lower house 11 is plastic material, and described air pressure button 12 is quality of rubber materials.
Using technique scheme, an accurate liquid extracting device of the present utility model, during use, it is located at reservoir with thumb pressure
The air pressure button on top, after discharge part air inserts dropper in reagent solution, unclamps thumb, reagent solution can suck dropper and go forward side by side
Enter in reservoir, generally, we install required dropper on transfusion device, and the internal volume of dropper is constant, so,
The reagent solution of the volume required for storing in dropper, unnecessary reagent solution can enter in reservoir, therefore when continuation is to strip
When instilling reagent solution, the reagent solution in reservoir will not again flow into determines liquid pipe, thus only by quasi- for the reagent solution in dropper ground
Drip in strip it is ensured that instilling the accuracy of reagent solution；Dropper can be changed as needed, and is needing liquid storage
It is only necessary to unload dropper when reagent solution in device is cleared up, you can discharge reagent solution.
Obviously, above-described embodiment is only intended to clearly illustrate example, and the not restriction to embodiment.For
Change or the change of other multi-forms for those of ordinary skill in the art, can also be made on the basis of the above description
Dynamic.There is no need to be exhaustive to all of embodiment.And the obvious change thus extended out or change
Among the dynamic protection domain created still in this utility model.
