Description

[Detailed description of the invention] (Industrial application field) This invention is designed to separate blood collected from a supplier into blood cell components and plasma components using a centrifuge, etc., and then to store the blood plasma components. This invention relates to improvements in containers for storing ingredients.

(Prior Art) A conventionally used plasma component storage container is shown in FIG.

In the figure, 20 is a plasma component storage container, 21 is an introduction tube, 22 and 23 are mixed injection ports, 24 is a protector, and 25 is an introduction needle.

The plasma component storage container 20 is made of a synthetic resin that can withstand low temperatures, such as polyolefin resin such as polyvinyl chloride, ethylene vinyl acetate, or tetrafluoroethylene-ethylene copolymer.

Blood collected from a blood donor is separated into blood cell components and plasma components using a centrifuge or the like. Plasma components are pooled in blood component storage containers, frozen at -20°C or lower, and stored for long periods of time.

The preserved plasma components serve as raw materials for various fractionated preparations such as albumin preparations.

Wash the surface of the plasma-containing blood component storage container 20, which is stored frozen at -20°C or lower, with distilled water and an alcohol aqueous solution until the plasma inside is slightly dissolved. The plasma is cut with a cutter knife, etc., and the plasma components are dropped into a plasma pool tank and processed into various fractionated preparations.

(Problems to be solved by the present invention) In the conventional method as explained above, each end of the plasma component storage container must be cut manually one by one. This is a very time-consuming process that is hindering automation.

Furthermore, when cutting with a cutter knife or the like, it has been pointed out that there is a sanitary problem because the cutter knife comes into contact with plasma components. Furthermore, the use of sharp cutting tools such as cutter knives was extremely dangerous as they could injure the people working on them and could potentially infect them with various viruses.

Therefore, the present invention was proposed as a result of studies to solve the above-mentioned problems.

(Means for Solving the Problems) In order to solve the above problems, the present invention provides at least one cut groove or fragile portion on either the inner or outer surface of the blood component storage container body. The present invention provides a container for storing blood components.

(Function) Hold the end of the blood component storage container consisting of the mixed injection ports 2, 3, the introduction tube 4, the introduction needle 5 and the locking grooves 6, 7, 8, 9, and apply force in the vertical direction to the cut groove 10. By adding this, the blood component storage container is torn open and the frozen plasma components are taken out.

(Example) FIG. 1 shows an example of the plasma component storage container 1 of the present invention.

The plasma component storage container 1 is composed of mixed injection ports 2, 3, an introduction tube 4, an introduction needle 5, a cut groove 10, or a weakened portion 10'.

Specific examples of the structure of the cut groove 10 or the weakened portion 10' are shown in FIGS. 2 to 5.

In FIG. 2, cut grooves 10 are provided on the inner surfaces of two sheets 31 and 32 in the length direction of the plasma component storage container 1, and sheet ends 33 and 34 are bonded by bonding means such as high frequency welding and ultrasonic welding. A sectional view taken along line A-A in FIG. 1 of the bag-shaped structure is shown.

In FIG. 3, cut grooves 10 are formed on the outer surfaces of two sheets 31 and 32 in the longitudinal direction of the plasma component storage container 1, and the sheet ends 33 and 34 are bonded by high-frequency welding or high-frequency welding to form a bag. 1 is a cross-sectional view taken along line A-A in FIG. 1.

Further, the cut grooves 10 shown in FIGS. 2 and 3 can be formed by extrusion molding, for example.

FIG. 4 shows the end portion 3 of two sheets 31 and 32.
3 and 34 into a bag shape by high frequency welding, ultrasonic welding, etc., is shown in a cross-sectional view of a place where a fragile portion 10', which is generated when forming parts 3 and 34 into a bag shape by high frequency welding, ultrasonic welding, etc., is provided at the center of the outer surface of the plasma component storage container 1.

End portion 3 of plasma component storage container 1 shown in FIG.
3 and 34 are provided at the center of the inner surface of the plasma component storage container 1.

Above, a specific example was shown in which the cut groove 10 and the fragile portion 10' were provided on the inner or outer surface of the plasma component storage container.
Any other structure may be used as long as the plasma component storage container 1 can be easily torn apart.

Next, a method of using the plasma component storage container 1 according to the present invention will be briefly explained.

Plasma components collected and separated from each blood donor are collected in the plasma component storage container 1 through the introduction tube 4 via the introduction needle 5.

Plasma components 1 to 3 obtained from blood donors are collected in a plasma component storage container 1, and immediately frozen and stored at -20°C or lower.

The preserved plasma components can be stored for a long period of time and are processed into various fractionated preparations.

When taking out the plasma component from the plasma component storage container 1, the surface of the plasma component storage container 1 is washed by pouring distilled water, an aqueous alcohol solution, etc., and the surface of the plasma component is thawed.

Next, the case of mechanically tearing the plasma component storage container 1 will be explained with reference to FIG. 6.

FIG. 6 shows a schematic diagram of the cutting device 11, in which 12a and 12b are vertically slidable plasma component storage container holding plates 13, 14, 15, 16.
17 is the retaining plate 1 for the plasma component storage container.
Fixed guide for expanding 2a and 12b laterally,
18 indicates a fulcrum, and 19 indicates a plasma pool tank.

Locking pin 1 provided on retaining plates 12a and 12b
3, 14, 15, and 16 are engaged with the engagement grooves 6, 7, 8, and 9 of the plasma component storage container. When the fixed holding plates 12a and 12b are moved downward, the holding plate 1
2a and 12b are attached to the holding plate 1 by the fixed guide 17.
The plasma component storage container 1, whose lower ends 2a and 12b are moved outward about the fulcrum 18 and fixed to the holding plates 12a and 12b, has 12a and 12b, respectively.
An outward force is applied to the 12b side to separate the cut groove 10 or the weak portion 1 to the 12a and 12b.
It is torn along 0'.

The plasma component in the plasma component storage container 1 falls into a plasma pool tank 19 provided in advance below the cutting device 11.

Such a cutting device 11 can also be used, and the plasma components collected in the plasma component storage container 1 can be taken out without bringing foreign objects such as a cutter knife into contact with the plasma components.

In addition, it is now possible to tear the plasma component storage container with less force, and it has become possible to process large quantities of plasma components through automation.

(Effects) As explained above, according to the present invention, it is possible to process mechanically, and a large amount of processing can be performed in a short time.

It is very hygienic as plasma components can be removed without bringing foreign objects such as a cutter knife into contact with the plasma components.

Since it does not require a sharp knife such as a cutter knife, it has become possible to prevent virus infection from wounds without injuring the worker.

It has excellent effects such as.
