Abstract

A long-acting biochemical reagent bottle comprises a bottle body, bottle mouths and a bottle cap, and is characterized in that two bottle mouths are arranged on the bottle body, and a cylindrical body is formed by vertically extending into the bottle body from one of the bottle mouths; the inner diameter of the cylindrical body is 5 to 7 mm, and the lower edge of the cylindrical body is 3 to 6 mm away from the bottle bottom; and small holes are formed on the wall of the cylindrical body. The utility model achieves the purpose of delaying the disintegration of reagent through the method of preventing the reagent from being in contact with flowable air, so that the effect of delaying the disintegration of various biochemical reagents in the open bottle is remarkable, the stability of the reagent in the open bottle can be efficiently improved, the validity period of the reagent is prolonged, and the daytime variation CV of testing results is remarkably lowered. Therefore, the reagent bottle has significance to both the cost control and the quality control of a laboratory.

Description

Long-acting biochemical reagents bottle

(1) technical field: the utility model relates to the biochemical test equipment, is a kind of long-acting biochemical reagents bottle.

(2) prior art: the decaying phenomenon after the biochemical reagents uncork is the FAQs in the clinical chemistry test work, the decay of reagent can cause testing result the tendency variation to occur, when the decay degree surpasses the scope of reagent factory settings, then be judged as inefficacy, so the decay of reagent bottle after uncapping becomes and influence the key factor that reagent effect phase and testing result make a variation in the daytime.

Biochemical investigation reagent effect phase under Kaifeng state not is generally 1 to 2 year, and the effect phase that is written into Biochemical Analyzer after the uncork then often has only 15 days to 3 months, even shorter.The air of long-term contact flow volatilizees after main cause and the reagent uncork, oxidation (or reduction), deliquescence, crystallization or germ contamination etc. are relevant, and reagent active ingredient is degraded gradually.This natural decay process is capable of blocking usually and can only delay by means of different.

(3) summary of the invention: the utility model is exactly to provide a kind of long-acting biochemical reagents bottle that can effectively delay biochemical reagents decay after the uncork at the problems referred to above.

Concrete scheme of the present utility model is: long-acting biochemical reagents bottle, have bottle, bottleneck and bottle cap, it is characterized in that: design has two bottlenecks on bottle, and vertically in bottle, extend into cylindrical body from one of them bottleneck, described cylindrical body internal diameter 5-7mm, its lower edge 3-6mm at the bottom of the bottle, and on the tubular body wall, have aperture.

Aperture on the described tubular body wall is apart from bottleneck 15～20mm, and diameter is 0.5～1mm.

The utlity model has following advantage:

1. remarkable to the decay effect after delaying various biochemical reagents and uncapping, can effectively improve stability after the reagent uncork, prolong reagent and imitate the phase, significant for the laboratory cost control.

2. can effectively reduce the CV of variation in the daytime of testing result, the laboratory inspection quality is significant for improving.

3. can effectively prolong the calibration cycle of all kinds of biochemical projects, help reducing the cost of reagent, caliberator and Quality Control thing.

4. the utility model production cost is close with common biochemical reagent bottle, but has superior performance, and alternative traditional common biochemical reagent bottle is widely used in automatic clinical chemistry analyzer and detects.

The performance parameter of the utility model and common biochemical reagent bottle is (seeing the following form) relatively

The performance of long-acting biochemical reagents bottle and common biochemical reagent bottle relatively

(5) specific embodiment:

Referring to Fig. 1, making material of the present utility model is a common plastics, have bottle 1, bottleneck 2 and bottle cap 3, bottle thickness 1mm, particularly: also designing on the bottle 1 has bottleneck 4 and bottle cap 5, and vertically extends into cylindrical body 6 from bottleneck 4 in bottle 1, described cylindrical body 6 internal diameter 5mm, its lower edge also is 5mm at the bottom of bottle, and has the aperture 10 that a diameter is 1mm apart from bottleneck 20mm place on the tubular body wall, promptly constitutes the utility model.

Principle of the present utility model (referring to Fig. 1, Fig. 2): after the general reagent bottle is uncapped, but area that the reagent liquid level contacts with moving air and whole bottle floor space sizableness, and after the utility model uncaps, but reagent 8 liquid levels and moving air contact portion, its area size equates with reagent bottleneck 4 areas, is significantly smaller than the general reagent bottle.Though the contact area of air in the utility model reagent 8 liquid levels and bottle 1 dead space 9, approximate a bottle floor space, but because air does not have flowability (though have aperture 10 on the tubular body wall in the dead space 9, but because its diameter is minimum, can not cause flowing of dead space 9 interior air), therefore can not cause the quick decay of reagent 8.And on the tubular body wall, open the purpose of aperture 10, be to allow the bottle outer air slowly enter in the dead space 9, to keep dead space 9 inner air pressures and external air pressure balance, make cylindrical body 6 interior liquid levels and dead space 9 interior liquid levels reach double altitudes, thereby make amount of reagent in the automatic biochemistry analyzer reagent needles energy correct detection bottle.Performance master's evaluation test of being undertaken by a large amount of biochemical investigation projects confirms, this structure for improve stability after the reagent uncork, prolong reagent imitate the phase, reduce assay make a variation in the daytime (CV) have remarkable effect.

The utility model use (referring to Fig. 2):

1. reagent can:

Bottleneck 2, bottleneck 4 all are open state, and an optional bottleneck carries out the reagent can for producer; When carrying out the reagent interpolation in the laboratory, available bottle cap 5 sealing bottlenecks 4 are poured into from bottleneck 2.

2. the machine of going up is prepared: seal bottlenecks 2 with bottle cap 3 before going up machine.

3. duty: reagent needles 7 stretches into from bottleneck 4 and surveys and draw reagent 8 in the cylindrical body 6.
