Description

Liquid preparation tank

Technical Field

The utility model relates to a medicine field. Specifically, the utility model relates to a join in marriage the fluid reservoir.

Background

In the blood product production process, a plurality of different types and different amounts of buffer solutions are required. Some products require up to 30 more buffers. Various buffers are required to be formulated and used in the container. For buffer solution with more dosage, the buffer solution is generally prepared in a fixed stainless steel tank of a solution preparation area and is conveyed to the use point of each area for use; and aiming at the buffer solution with a small dosage, the materials are dispensed from the solution preparation area and are prepared at the use points of each area for use.

The buffer solution which is used in relatively small amount and needs to be prepared to the use points of each area is prepared by a common open stainless steel barrel or a stainless steel milk barrel with a small opening.

The method comprises the steps of placing a clean empty barrel on an electronic platform scale to remove the skin and reset, taking the barrel to a water point to be connected with injection water, lifting a stainless steel barrel filled with water onto a trolley, moving the stainless steel barrel to a room where the electronic platform scale is placed, moving the stainless steel barrel to the electronic platform scale to weigh, adding materials while stirring, and supplementing the injection water according to the weight. If the pH needs to be adjusted, the pH is adjusted for standby.

Because the stirring mode is manual stirring, the cover needs to be opened, the exposure operation time is long, and the buffer solution is easily polluted. Moreover, the buffer solution is drawn from the top when in use, a cover needs to be opened, and the buffer solution is exposed for a long time, so that the risk of being polluted is also existed. The uncapping operation time is long, and the risk of introducing microorganisms and bacterial endotoxin into a buffer solution is high; excessive decap is often considered a risky operation in GMP field checks in the pharmaceutical industry, particularly the blood products industry.

In addition, the conventional open stainless steel barrel and the stainless steel milk barrel are inconvenient to move and need two persons to operate. In addition, the operation is very laborious when the existing stainless steel barrel is cleaned, and especially, the stainless steel milk barrel needs to be inclined and inverted, so that the cleaning solution can completely flow out, and a cleaning dead angle exists. In addition, when the buffer solution is pumped out, the buffer solution at the last point is not pumped completely, and the phenomenon of material waste exists in the production.
