Description

Novel safe preparation device for large-capacity reagent

Technical Field

The utility model relates to a technical field is prepared to reagent, concretely relates to novel large capacity reagent is prepared safely device.

Background

In the field of in vitro diagnostic reagents, the dosage of the buffer solution prepared by chemical reagents is continuously increased along with the mass sale of products, part of production instruments used before the products are amplified are not suitable, and the problems of improving the production process and accurately controlling the production process after the products are amplified, improving the product quality, reasonably and safely protecting operators and the like need to be comprehensively considered and solved. At present, the field of in vitro diagnostic reagents has larger difficulty or has a tool for simple amplification, but partial problems are not solved.

When large-dose chemical reagents are produced and prepared, various chemical reagents need to be weighed, and the reagents also comprise reagents which need a large amount of dangerous chemicals or whole bottles of dangerous chemicals, such as hydrochloric acid, sulfuric acid, nitric acid, sodium hydroxide, potassium hydroxide, hydrogen peroxide, carbamide peroxide and the like. In the production process, the materials are added while stirring, or dangerous chemicals such as hydrochloric acid, sodium hydroxide and the like are added in the stirring process to adjust the pH value, so that the pH value of the reagent reaches an ideal state. Because some dangerous chemicals have strong corrosivity or volatility, throw the material while stirring, the dangerous chemicals of volatility can produce the corruption to the electric stirrer on jar mouth upper portion, also can produce harm to operating personnel's personal health (because for the chemical reagent preparation process of large dose, the jar body is bulky, heavy in weight, it is unrealistic to put inside the fume hood, when using powerful magnetic stirrers, because powerful magnetic stirrers magnetic force is bigger, it is very to the rotor adsorption affinity of major diameter and major length, can make rotor and jar body bottom produce very big friction in the in-process of stirring, thereby wearing and tearing fall the polytetrafluoroethylene material on rotor surface, can increase partly should not have impurity originally to the reagent, need filter away, increase manufacturing cost and technology complexity). Therefore, when a large amount of chemical agent needs to be prepared, an electric stirrer is generally used for stirring and mixing from the top of the large-volume container in the tank body, and the above-mentioned part of unsafe operation and influence exist.

Detailed Description

The following examples are provided for better understanding of the present invention, and are not limited to the best mode, and do not limit the scope and content of the present invention, and any product that is the same or similar to the present invention, which is obtained by combining the features of the present invention with other prior art or the present invention, falls within the scope of the present invention.

Examples

Referring to fig. 1-2, a novel high capacity reagent safety dispensing device, the dispensing device comprising: a tank body 1 and a funnel-shaped long-handle feeder 2.

The upper end of the tank body 1 is provided with a sealing cover 3, the sealing cover 3 is provided with a first opening 4, the side wall of the tank body 1 is provided with a second opening 5, and the diameters of the first opening 4 and the second opening 5 are both 500 mm.

Funnel-shaped long-handle feeder 2 is including throwing material chamber 6 to and locate throwing material pipe 7 of throwing the lower extreme of material chamber 6, and throwing material pipe 7 is the slope setting, throws and is equipped with two handles 8 on the material chamber 6, and throwing material pipe 7 can pass first opening 4 or second opening 5 and arrange in jar body 1. Wherein, batch feed pipe 7 sets up for the slope, conveniently throws the material angle of a slope occasionally, touches the stirring rake when can avoid throwing the material, and batch feed pipe 7's material requires low adsorptivity, corrosion-resistant, acid and alkali-resistance, easy washing, inner wall are smooth, and pot hole or recess or protruding part do not have or less. Throw material chamber 6 and can prevent that reagent from overflowing excessively, handle 8 makes things convenient for operating personnel to support, prevents that the slope makes reagent spill over to laboratory ground harm environment and operating personnel.

This embodiment is when preparing the buffer solution of large-dose chemical reagent, in order not to influence the normal operating of stirring rake, in order to prevent that volatile gas directly from rising to corrode electric mixer and operating personnel, need prepare independent telescopic negative pressure evacuating device earlier, stirring rake 9 inserts from first opening 4, feeding pipe 7 inserts from 5 departments of second opening, makes feeding pipe 7's bottom be close to liquid level department, begins to throw the material with stirring rake 9 while stirring, and is safe again convenient promptly. The independent telescopic negative pressure vacuum pumping device can be selected according to actual requirements, and if nonvolatile and strong corrosive liquid is not used, the tool can be omitted, but the problem of generating negative pressure by other methods can also be solved.

The embodiment can improve the production efficiency, simplify the production process, reduce the production cost, promote safe production and reduce the equipment loss and the personnel injury probability.

It should be understood that the above examples are only for clarity of illustration and are not intended to limit the embodiments. Other variations and modifications will be apparent to persons skilled in the art in light of the above description. And are neither required nor exhaustive of all embodiments. And obvious variations or modifications can be made without departing from the scope of the invention.
