出管に封をしたものである。 Conventionally, cryopreservation bags have been used to rapidly freeze and preserve blood using liquid nitrogen or the like. This frozen storage bag is made by laminating sheets made of synthetic resin together to form a sealed bag, and the walls of this bag are equipped with a storage tube and a discharge tube for the liquid to be stored, such as blood, which can communicate between the inside of the bag and the outside. The storage tube and discharge tube are sealed.

入し難い欠点があつた。 However, in the case of such conventional freezer storage bags, since the freezer storage bags are placed in liquid nitrogen at approximately -196°C, they must be made of material that can withstand this. The material for both the pipe and the discharge pipe is tetrafluoroethylene.
Polyethylene copolymer resin or its equivalent is used. For example, when tetrafluoroethylene or polyethylene copolymer resin is used as the material for the storage pipe and discharge pipe, its melting point is approximately 300°C and it is not as good as a synthetic resin material. Because of the relatively high cost and the need to make relatively long housing and discharge pipes, these housing and discharge pipes are manufactured by injection molding. The drawback was that it was difficult to fill and manufacturing was difficult. Therefore, the thickness of the storage pipe and the discharge pipe must be relatively thick, and this, combined with the fact that the above-mentioned materials are hard near room temperature, make the storage pipe and the discharge pipe relatively thick. The blood becomes so hard that it is difficult to crush it, and for this reason, after blood is put into the above-mentioned cryopreservation bag from the storage tube, the base bag wall of this storage tube is sealed by fusion, but the blood storage The drawback was that the volume was small. In addition, when putting blood and blood preservation solution into the above-mentioned cryopreservation bag or discharging blood and blood preservation solution from this bag, the inner diameter of the storage tube or discharge tube should be A needle with approximately the same outer diameter is inserted, and blood and blood preservation solution are injected or discharged into or from the cryopreservation bag through the tube connected to this needle. However, the inner diameter of the housing tube and the discharge tube and the outer diameter of the needle are approximately the same, and the needle is difficult to insert because the housing tube and the discharge tube are hard and have no elasticity.

A storage tube and a discharge tube for the liquid to be accommodated are formed so that the wall thickness of a pair of opposing portions of the tube wall is a minimum wall thickness portion that is thinner than the other portions of the tube wall, and the tube wall is connected to a sealed bag body. By providing the wall so that the interior of the bag body communicates with the outside, it can be easily manufactured, and the storage tube can be easily sealed.
It is an object of this invention to provide a cryopreservation bag for blood, etc., which can sufficiently store a liquid to be frozen.

排出する。 When blood and blood preservation liquid are put into the bag body 1, a needle (not shown) having an outer diameter approximately the same as the minimum inner diameter of the accommodation tube 5 is inserted into the accommodation tube 5.
is inserted, and blood and blood preservation fluid are injected and stored through this needle by a blood pump (not shown) from a tube connected to this needle. After the blood and blood preservation liquid have been stored in the bag body 1, predetermined portions of the storage tube 5 are crushed in the directions of arrows A and B in FIG. 2 and these portions are fused together. At this time, the wall thickness of the housing tube 5 is set at the minimum wall thickness of the pair of opposing portions of the tube wall in the direction perpendicular to the directions of arrows A and B, and stress is concentrated in this portion, so it is extremely easy to crushed. Further, when the accommodation tube 5 is crushed, the minimum wall thickness portion 5c is thin, so this portion does not bulge inward, so that the opening can be closed without any gaps. Therefore, this portion can be fused extremely easily and reliably. Further, the blood and blood preservation liquid contained in the bag body 1 will not be discharged from the discharge pipe 6 because the discharge pipe 6 is closed by the seal membrane 7. Thereafter, the frozen storage bag is frozen and stored using well-known means. Also,
When using the blood stored in this way, it should be thawed by a well-known method and then used with a needle similar to the needle inserted into the storage tube 5 (a needle with an outer diameter that is approximately the same as the minimum inner diameter of the discharge tube 6). ) is pierced through the seal membrane 7 and inserted into the discharge tube 6, and the blood and blood preservation liquid in the bag body 1 are suctioned and discharged through this needle and the tube connected to this needle.

挿入は極めて容易となる。 As explained above, according to this invention, the storage pipe and the discharge pipe are formed so that the wall thickness of the other part of the pipe wall is thicker than the wall thickness of a pair of opposing parts of each pipe wall. During this process, the mold is filled with material up to every corner, making manufacturing easier. In addition, since the wall thickness of a pair of opposing portions of the tube wall of the receiving tube is formed to be the minimum wall thickness portion which is thinner than the other portions of the tube wall, even if the other portions of the tube wall are When crushing a containment tube even if it is thicker than the wall thickness, the stress concentrates on the minimum wall thickness, so the containment tube can be crushed very easily, and the containment tube can be reliably closed and the blocked part can be easily fused. can be worn. Further, if the normal cross-sectional shape of the inner hole of the accommodation tube and the discharge tube is formed into a substantially elliptical shape, and the minimum diameter of the inner hole is made approximately equal to the outer diameter of the needle inserted into the accommodation tube and the discharge tube. When inserting the needle into the accommodation pipe or the discharge pipe, the inner holes of the accommodation pipe or the discharge pipe can be deformed into shapes close to circular in cross section, so the needle can be inserted loosely into the accommodation pipe or the discharge pipe. This makes needle insertion extremely easy.
