Description

  The present invention relates to a bag-like container for storing a dialysis agent such as a powdery or granular solid dialysis agent used for preparing a dialysis solution used for artificial dialysis.

There are two types of dialysis agents, liquid and solid. Since most liquid-type dialysis agents are occupied by water, and the weight and capacity are increased, the load of transportation work for dialysis medical workers is increased, and the storage space is also increased. Therefore, in recent years, when using dialysate, a solid-type dialysis agent (hereinafter referred to as solid dialysis agent), which is introduced into an automatic dissolution apparatus and dissolved in water to prepare a dialysis solution, has rapidly spread. ing. Currently, there are two types of containers for storing the solid dialysis agent: a bag type and a bottle type.

FIG. 3 is a perspective view of the bag-type dialysis agent storage container as viewed obliquely from below.

The bag-type dialysis agent storage container 1 is generally composed of a cylindrical body portion 2 made of a flexible sheet material, and a bottom portion 3 made of a flexible sheet material provided in the lower portion of the body portion 2. ing. As the flexible sheet material, for example, a flexible synthetic resin sheet material (film material) such as a polyester laminate film material or a polyethylene film can be used, and the body portion 2 has higher strength than the bottom portion 3. It is preferable that the bottom part 3 is weaker than the body part 2 so that it can be easily broken by a cutter. In addition, in embodiment shown in drawing, the trunk | drum 2 laminated | stacked the polyester film of thickness 10-50 micrometers, the silicon oxide vapor deposition polyester film of thickness 10-50 micrometers, and the polyethylene film of thickness 50-100 micrometers. A laminate film is used, and a polyethylene film having a thickness of 10 to 100 μm is used for the bottom 3.
In the present embodiment, two flexible sheet materials are overlapped, and the left and right side edges thereof are welded (or fused) to form a cylindrical trunk portion 2 having a substantially lobed or substantially boat-shaped cross section. The upper end opening of the body portion 2 is sealed by welding (or fusing) the upper end edges of the flexible sheet material, and a horizontally long hole is opened as a hanging portion 5 in the approximate center of the sealing portion 4. . In addition, a substantially spindle-shaped sheet material in plan view that is bent in a bowl shape or a pocket shape is fastened to the lower portion inside the barrel portion 2 to form the bottom portion 3, and is surrounded by the sealing portion 4 at the upper end, the bottom portion 3, and the trunk portion 2. This space is used as a dialysis agent storage space 6, and the lower end opening of the body 2 located below the bottom 3 is sealed by welding (or fusion) or the like, thereby sealing the outer surface of the bottom 3. The lower end portion of the body part 2 is covered so as to prevent adhesion of dust and germs.

There is no problem at this stage.

  And, when used, that is, when thrown into the melting device, the lower end portion 8 of the body portion 2 can be excised between the sealing portion 7 at the lower end and the bottom portion 3, and the outer surface of the bottom portion 3 in the excised state. Is configured to be exposed in the lower end opening. The step of sealing the upper end opening of the body portion 2 is actually after a predetermined amount of the dialysis agent 10 is filled in the dialysis agent storage space 6.

  The dialysis agent 10 stored in the bag-type dialysis agent storage container 1 is provided in two types of agent A and agent B in order to prevent chemical reaction during dissolution. Agent A is a drug containing components such as glucose, sodium chloride, and magnesium chloride, and Agent B is a drug mainly composed of sodium bicarbonate. In order to prepare the dialysate, for example, 2682.0 g of agent A and 661.6 g of agent B are used. Therefore, in the embodiment shown in the present example, the dialysis agent storage container 1 is set to a capacity capable of storing the amount used for adjusting the dialysate. For example, the capacity of the dialysis agent storage container 1 for agent A is about 3 liters (width of about 23 cm, height of about 40 cm), and the capacity of the dialysis agent storage container 1 for agent B is about 1 liter (width of about 23 cm, The height is set to about 13 cm) so that the dialysis agent storage container 1 can be identified simply by looking.
