DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a dialysis agent container containing a powdery or granular dialysis agent used for adjusting a dialysate used for artificial dialysis.

[0002]

2. Description of the Related Art One type of dialysate is a bicarbonate type dialysate. Most of the dialysis agents for adjusting the dialysate are divided into an A agent and a B agent in order to prevent a chemical reaction during dissolution. It is provided separately. Agent A is glucose, sodium chloride,
It is a drug containing components such as magnesium chloride, and the agent B is a drug mainly containing sodium hydrogen carbonate. These drugs are stored in a container such as a bottle made of resin (for example, polyethylene) having a capacity of 2 to 4 liters, and stored and transported, in the form of powder or granules. After being dissolved in the dissolving device, the drug is adjusted to a predetermined concentration by the diluting device and used as a dialysate.

In recent years, disposal of refuse has emerged as a major problem, and disposal of resin bottles used for dialysis solvent containers is no exception. That is, even if the bottle is used and emptied, the volume does not change, so that the bottle becomes bulky garbage and the disposal is troublesome. As a container that can reduce the bulk after use, it is conceivable that the container is formed of a bag like a container of an infusion liquid.

[0004]

However, if the container for the dialysis agent is a bag, the bag is crushed when the cutter or nozzle is inserted into the bag after being set in the dissolving apparatus. Even if the nozzle can be inserted, the shape of the bag is unstable, so when the water is supplied from the nozzle into the bag and dissolved, the solution is easily spilled, and it is difficult to dissolve and remove the entire amount of the drug. Will be. Thus, simply changing a resin bottle to a bag as a container for the dialysis agent cannot be put to practical use.

[0005] The glucose constituting the component of the agent A is
Long-term contact with other components, for example, an electrolyte component such as sodium chloride, causes deterioration and discoloration. As a countermeasure, it has been practiced to package the agent A separately into glucose and other components. Specifically, a dialysis agent is divided into three types of drugs, glucose, a component of the A agent other than glucose, and B agent, and each of the agents is individually stored in a container. . However, three dialysis agents
When divided into different types of drugs and each drug is stored individually,
The number of waste bottles after use further increases, and as a result, there arises a problem that the waste capacity (bulky) increases. For this reason, the waste capacity can be reduced by using a special compression device or a crushing device, but there is a problem of installation cost, labor cost and labor involved in this. In addition, when glucose and the constituent components of the agent A other than glucose are individually stored, it is necessary to adjust the mixing ratio of the agent A when dissolving, which is troublesome.

The present invention has been made in view of the above-mentioned circumstances, and an object of the present invention is to easily reduce the volume after use (volume reduction).
It is intended to provide a container for a dialysis agent that can be used.

[0007]

Means for Solving the Problems The present invention has been made to achieve the above object, and the invention according to claim 1 is to form a flexible film material into a tube shape and seal one end thereof. A closed container body, and a lid member having a take-out portion sealed with a breakable seal material, and a lid member provided to close the other end opening of the container body. A receiving portion for receiving a pressing force from the dissolving device provided on the lid member.

[0008] According to a second aspect of the present invention, there is provided a dialysis agent container for storing a dialysis agent comprising a plurality of components containing glucose as one component. It has a sealed container body, a lid member having a take-out portion sealed with a breakable seal material, and a lid member provided so as to close the other end opening of the container body, and restores the middle of the container body. A dialysis agent characterized in that it is crushed as much as possible and the interior is divided into two chambers, and that dry glucose can be stored in one chamber and other components can be separately stored in the other chamber.

[0012]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a perspective view of a container 1 for a dialysis agent according to the present invention, and FIG. 2 is a cross-sectional view showing a state where the container 1 is set in a dissolution apparatus.

The dialysis agent container 1 is used for storing the agent A in the dialysis agent for bicarbonate dialysis, and comprises a lid member 2 and a container body 3 joined to the lid member 2. Is done.

The cover member 2 has a take-out portion 5 provided substantially at the center of the upper surface of the circular cover plate portion 4, and a cylindrical joining portion 6 having a smaller diameter than the cover plate portion 4 is provided on the lower surface of the cover plate portion 4. The outer peripheral edge portion of the cover plate portion 4 which protrudes outward from the joint portion 6 in a flange shape is a protruding portion 7.
The take-out portion 5 is formed by forming a cylindrical opening 10 in the lid plate portion 4 and attaching a breakable film-like sealing material 11 to the upper end edge of the opening 10 with an adhesive. The container 1 is hermetically sealed with the material 11. The protrusion 7
Is for supporting the container 1 when dissolving the agent A by the dissolving device and for receiving the pressing force applied from the dissolving device, and for sealing the sealing material 11 with a force when breaking and a liquid-tight seal. It functions as a receiving portion that receives the seal pressing force applied to the seal. Therefore, the projecting portion 7 is not limited to the flange shape, and may be an ear piece shape. In addition, as shown in FIG. 3, the portion functioning as the receiving portion may be a tapered portion 8 whose diameter is reduced downward on the outer peripheral surface of the joining portion 6.

The container main body 3 is a bendable bag body in which a film material made of a flexible resin such as polyethylene is formed into a vertically long tube and one end is sealed. The opening at the other end of the container body 3 is used when the lid member 2 is injection-molded.
It is joined to the outer surface of the joining portion 6 and integrated. Therefore, the joint 6 between the container body 3 and the lid member 2 has sufficient strength and also maintains sufficient airtightness. In addition, one end serving as the bottom of the container body 3 may be linear or curved as long as it is airtightly sealed, or may be of a standing pouch type. The opening at one end may be sealed after the A agent is filled.

When filling the container 1 having the above-described structure with the agent A, in the present embodiment, the middle of the container main body 3 is crushably restored and the interior is divided into two chambers 12a and 12b. Dried glucose in the other room 12
By storing the other components separately in b, glucose is stored in a state of being separated from the other components. The position where the container body 3 is crushed is a position where glucose can be stored in one chamber 12a and another component (other than the glucose of the agent A) can be stored in the other chamber 12b.

In order to crush the middle of the container main body 3, the container main body 3 is folded in a substantially Z-shape at a position away from the lid member 2 by a predetermined length to form a bent portion 13. When the bent state of the bent portion 13 is maintained, the interior is divided into two chambers 12a,
12b.

As long as the bent portion 13 can maintain its shape by the pressing force when folded,
When it is intended to restore the original state by the characteristics of the film material constituting the container body 3, specifically, the restoring force (elasticity), the bent portion 13 is shaped by applying shape keeping means. For example, the bent state may be maintained by heating the bent portion 13, or an auxiliary tool such as a clip may be used. Further, it may be fixed with an adhesive tape or temporarily bonded with a removable adhesive. In addition, the tape which can be easily peeled is used. Further, it is preferable to provide a margin at the end of the tape in order to facilitate the work of peeling the tape. In short, any shape-retaining means may be used as long as it can maintain a state in which the interior of the container body 3 is partitioned into two chambers 12a and 12b by crushing the middle of the container body 3. The number of times the container body 3 is folded is not limited to one time, and may be folded several times.

As described above, when the sufficiently dried powdered glucose is stored in one chamber 12a of the container 1 and the other components other than glucose are stored in the other chamber 12b, the glucose becomes It is isolated from electrolyte components such as sodium chloride and does not deteriorate even after long-term storage. Note that components other than glucose may be stored in the chamber 12a on the lid member 2 side, and glucose may be stored in the chamber 12b.

When the agent A is used, that is, when the agent A is dissolved, the two chambers 12a, 1 partitioned by unfolding (extending) the bent portion 13 of the container body 3 are opened.
2b communicates with one chamber to mix glucose and other components.

Then, the mixed agent A in the container 1 is dissolved by the dissolving device, and a concentrated dialysate is prepared. Specifically, as shown in FIG. 2, the container 1 is supported with the protruding portion 7 placed on a container holder 15 provided on a turntable of the melting device, and the connecting member 16 of the melting device is lowered. Then, the cover member 2 is covered. In this state,
When the nozzle 17 penetrating the connecting member 16 descends, the cutter 18 provided at the tip of the nozzle 17
And the nozzle 17 is inserted into the container 1. In addition,
Since the pressing force when the cutter 18 breaks the seal material 11 is received by the projection 7 of the container 1, the flexible container main body 3 is not crushed. In addition, if a material that is easily broken is used as the seal material 11, the seal material 11 can be broken by inserting the nozzle 17 on which the cutter 18 is not formed.

In this manner, the nozzle 17 is provided inside the container 1.
Is inserted, water is supplied into the container 1 from the nozzle 17, and the water dissolves the agent A, and the concentrated solution of the agent A overflows out of the container 1 from the take-out part 5, and is discharged from the drain pipe 19. It is sent to the dilution device side. Then, after that, it is mixed with the agent B solution and adjusted to a predetermined concentration to be a dialysate.

In the container 1 used in this manner, the container body 3 is formed of a resin film bag.
When the agent A, which is the content, is discharged, it can be squashed simply by lightly pressing it by hand. Therefore, the bulkiness of the container 1 can be reduced, that is, the volume can be reduced, and the disposal can be facilitated.

In the above-described embodiment, the middle of the container body 3 is crushed by folding the container
Although a and 12b are formed, the means for crushing the container body 3 in the present invention is not limited to the above-mentioned folding.
Any crushing method may be used as long as the inside of the container body 3 can be partitioned into two chambers 12a and 12b. For example, the bottom (one end) side of the container body 3 may be turned back to the lid member 2 (other end) side in the longitudinal direction of the container body 3. In this case, the tape,
When the one end side and the other end side of the container main body 3 are fixed or bound by a wire, a string, or the like, the folded state can be maintained. In addition, an auxiliary tool that crushes the container body 3 by sandwiching the outer surface from both sides may be used.

Further, in the embodiment shown in FIG. 1, the container main body 3 in which the width of the folded portion is reduced is shown, but the width may be the same over the entire length. Further, the container body 3 was joined when the lid member 2 was molded, but the container body 3 was attached to the molded lid member 2.
May be joined. In short, it suffices if the lid member 2 can be joined to the bag-shaped container body 3 in a state where the airtight state can be maintained.

In the above-described embodiment, the container body is partitioned by the shape-retaining means, and glucose is supplied to one of the chambers.
The other room contains an A agent other than glucose to prevent the deterioration of glucose caused by long-term storage, thereby reducing the number of containers used, and allowing the protrusion to be mounted on the dissolution apparatus. Although the bulk of the used container is reduced by forming the container body with a flexible material whose volume can be reduced, the present invention is not limited to this. For example, the agent A containing glucose may be stored in the container 1 without partitioning the inside of the container 1. Also in this case, the container main body 3 is not crushed when set in the dissolving apparatus, and there is no hindrance to the dissolving operation.
Volume can be reduced.

[0027]

As described above, according to the present invention, the following effects can be obtained. The invention according to claim 1 has a container body of a dialysis agent container in which a flexible film material is formed in a tube shape and one end of which is sealed, and a take-out portion which is sealed with a breakable seal material. And a cover member provided so as to close the opening at the other end of the container body, and a receiving portion for receiving a pressing force from the dissolving device applied in a state of being attached to the dissolving device is provided on the lid member. When it is set in the apparatus, it can be set in a state where a load is not applied to the container body supported by the receiving portion. Therefore, in this state, even if the sealing material is broken by a cutter or the like from above, the container body is not crushed, and even if a sealing pressing force for maintaining a liquid-tight state is applied from the melting device, the container body is not crushed. It will not be crushed. Then, the container after use can be easily crushed to substantially reduce the volume of almost the entire container main body, thereby facilitating disposal processing. In addition, there is no need to significantly modify the melting apparatus.

According to the second aspect of the present invention, the middle of the container main body is crushed so as to be able to be restored, and the interior is divided into two chambers. By storing the components separately, glucose can be stored in a state of being separated from other components. Therefore, even if glucose is stored in the same container as other components, deterioration caused by contact between glucose and other components can be prevented. Therefore, there is no need to store glucose and other components in separate containers,
The number of containers used can be reduced. As a result, the waste capacity can be reduced.

According to the third aspect of the present invention, the interior of the container main body can be easily achieved because the interior of the container main body is divided into two chambers by folding in the middle of the container main body and crushing it in a restorable manner. Therefore, it is possible to avoid a complicated structure such as forming a partition wall inside, and it is easy to manufacture.

According to the fourth aspect of the present invention, since the receiving portion for receiving the pressing force from the dissolving device applied to the dissolving device while being attached to the dissolving device is provided on the lid member, the container can be crushed halfway and divided into two chambers. Even in the case of the main body, the container main body is not crushed when the sealing material is broken by being set in the melting device or when melting.

According to the fifth aspect of the present invention, since the receiving portion is constituted by the projecting portion formed on the lid member so as to project laterally from the container main body, the operation of setting the container in the melting device is performed. The operability is good, and even when the container body is made of a flexible material, the force during the melting operation can be reliably received by the projecting portion, and the load on the container body can be reliably eliminated. Therefore, troubles such as breakage of the flexible container body can be avoided.
