Abstract

The utility model discloses a biochemical reagent bottle which is characterized by comprising a bottle cavity, a first bottleneck, a second bottleneck, a first bottle cap and a second bottle cap. A hard round tube downwardly extends from the first bottleneck, the diameter of the hard round tube is identical to that of the first bottleneck, a notch is formed in the position, which is close to the first bottleneck, of the upper end of the round tube, a gap is formed between the lower end of the round tube and a bottle bottom, and the bottom of the round tube is communicated with the reagent bottle. The bottle bottom is a curved surface or a conical surface, and the lowermost point of the curved surface or the conical surface is opposite to the lower end of the round tube. Side walls of a bottle body extend out of the bottle bottom to form a stable ring surface, so that the reagent bottle can be supported. The biochemical reagent bottle has the advantages that the contact area of reagents in the bottle and air is reduced after the reagent bottle is opened, accordingly, the bottle opening stability of the reagents is improved, reagent residues can be reduced, and the reagent utilization rate is increased.

Description

A kind of biochemical reagent bottle

Technical field

The utility model belongs to technical field of medical instruments, relates to a kind of reagent bottle for Biochemical Analyzer.

Background technology

The reagent of automatic clinical chemistry analyzer is generally held in general vial or plastic bottle, after uncork is used, reagent in bottle inevitably will directly contact with air, through the large-area contact of a rapid lapse of time, the evaporation of oxidation, solvent very easily occurs or is subject to the harmful effect such as outside contamination in biochemical reagents, thereby affect reagent quality, cause assay inaccurate, and can shorten the holding time of reagent.At present, reagent bottle both domestic and external adopts at bottleneck and adds that criss-cross rubber diaphragm reduces contacting of reagent and moving air, but for full automatic biochemical apparatus, reagent lid contact reagent needles causes in various degree cross pollution even can have influence on the liquid level inducing function of reagent needles.As improvement, have in recent years offshore company to release the novel biochemical instrument type that employing robotic arm manipulation reagent bottle is uncapped and closed lid, but this design limitation popularize and have certain difficulty in specific apparatus.

The reagent of automatic clinical chemistry analyzer absorbs full automation, is provided with the liquid level warning system, when reagent is about to finish using, stops drawing reagent, syringe needle can not touched bottle fully at the bottom of inside surface, bottom can remaining one deck reagent.At present, at the bottom of the reagent bottle bottle that biochemical instruments is used, be generally in the middle of flat or bottom slightly protrudingly, lower on every side, liquid level is reported to the police when highly identical, and this reagent bottle can cause more reagent residual.If, for saving reagent, repeatedly in the bottle with residual reagent, add new reagent, also can affect test effect accuracy, and all higher for the reagent price of automatic clinical chemistry analyzer, reagent can not take full advantage of and can cause larger economic loss.

Technology contents

The technical problems to be solved in the utility model is: propose a kind of biochemical reagent bottle, the above-mentioned defect of existing container is improved or overcome, guarantee the stability of reagent in bottle, bottle interior reagent can be fully used.

The utility model solves the problems of the technologies described above the technical scheme that adopts: a kind of biochemical reagent bottle comprises a bottle chamber, the first bottleneck, the second bottleneck, the first bottle cap and the second bottle cap.It is characterized in that: the first bottleneck is to hard pipe identical with bottleneck diameter of downward-extension, and the pipe upper end, near bottle mouth position, is provided with breach, and the pipe lower end is gapped with bottle end recess.The pipe lower end is over against the minimum point at the bottom of bottle, and the body sidewall forms anchor ring stably at the bottom of extending bottle outlet, supports reagent bottle.

Particularly, the described bottle end is a curved surface or the conical surface, over against the pipe lower end, is the minimum point of curved surface or the conical surface.

Described the first bottleneck is to the pipe lower end and bottle end depression distance 3～6mm of downward-extension.

Described the first bottleneck is connected respectively by screw thread with the second bottle cap with the first bottle cap, the second bottleneck.

The bottleneck of described biochemical reagent bottle, hard pipe, bottle chamber and body sidewall extend the support ring that gets off can be integrally formed.

Compared with prior art, the beneficial effects of the utility model are:

1. the utility model is used for the first bottleneck of reagent bottle sampling to the downward-extension pipe, after reagent, air only contacts with the upper strata reagent in pipe, although the reagent in pipe can communicate with air, can by reagent needles, be drawn very soon, does not affect experimental result.Pipe is provided with breach, guarantees that intraductal atmospheric pressure is identical with tube pressure, and reagent can flow smoothly, and in intraluminal fluid face and bottle, liquid level reaches double altitudes, is convenient to amount of reagent in reagent needles correct detection bottle.This design has solved the problem of available reagent uncork poor stability, has extended the term of validity, and applicable type is many, and is significant for the biochemical investigation quality control.

2. the utility model is a curved surface or the conical surface for the bottle end of the first bottleneck of reagent bottle sampling, over against the pipe lower end over against curved surface or the minimum point of the conical surface, this design, the reagent that is about to use up is concentrated in a less space of recessed area, while remaining identical amount of reagent, liquid level is than general reagent bottle height, when the reagent surplus is atomic, the reagent liquid level just can be reported to the police highly lower than reagent probe, makes reagent needles stop drawing reagent.This design can reduce reagent residue, improves the reagent utilization factor, saves financial cost.
