Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a container for a dialysis agent that contains a powdered or granular dialysis agent used to adjust a dialysate used for artificial dialysis.
[0002]
[Prior art]
There is a bicarbonate-type dialysate as a kind of dialysate, and many of the dialysis agents for adjusting this dialysate are provided separately as agent A and agent B to prevent chemical reaction during dissolution. Yes. 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.
These chemicals are stored and transported by storing powdery or granular components in a container such as a 2 to 4 liter capacity resin (for example, polyethylene) bottle. And after a chemical | medical agent is melt | dissolved with a melt | dissolution apparatus, it is adjusted to a predetermined density | concentration with a dilution apparatus, and is used as a dialysate.
[0003]
By the way, in recent years, waste disposal has emerged as a major problem, and the disposal of resin bottles used in dialysis agent containers is no exception. In other words, even if the bottle is empty after use, its volume does not change, so it becomes bulky garbage, and disposal is troublesome.
It is conceivable that the container can be reduced in bulk after use, and is constituted by a bag like the container for drip liquid.
[0004]
[Problems to be solved by the invention]
However, if the container for the dialysis agent is constituted by a bag, the bag will be crushed when the nozzle is inserted after being set in the dissolution apparatus. Even if the nozzle can be inserted, since the shape of the bag body is unstable, when water is supplied from the nozzle into the bag body and dissolved, the solution is likely to spill and it is difficult to dissolve and take out the entire amount of the drug. Become.
Thus, as a container for a dialysis agent, the bottle cannot be put to practical use simply by changing the bottle into a simple bag.
[0005]
Moreover, the glucose which comprises the component of A agent will change in quality and discoloration, when it contacts with other components, for example, electrolyte components, such as sodium chloride, for a long period of time. As a countermeasure, the agent A may be divided into glucose and other components and packaged. Specifically, the dialysis agent is divided into three types of drugs, glucose, A component other than glucose, and B, and each drug is individually stored in a container. .
[0006]
However, when the dialysis agent is divided into three types of drugs and each drug is stored individually, the number of discarded bottles after use increases, resulting in a problem that the disposal capacity (bulkiness) increases. End up. In addition, the waste capacity can be reduced by using a special compression device or crushing device, but there are problems of installation cost, labor cost for engaging in this, and work load.
[0007]
Moreover, if the glucose and the components of the agent A other than glucose are separately stored, it is necessary to adjust the mixing ratio as the agent A when dissolving, which takes time.
[0008]
The present invention has been made in view of the above circumstances, and its purpose is to provide a container for a dialysis agent whose volume can be easily reduced (reduced volume) after use in order to facilitate disposal after use. It is what.

[0013]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to the drawings.
FIG. 1 is a perspective view of a dialysis agent container 1 according to the present invention, and FIG. 2 is a cross-sectional view showing an internal configuration of the container 1.
[0014]
The container 1 for dialysis is composed of a hollow core tube 3 having an opening 2 penetrating inside and outside on a side surface near one end, and a bag-like container body 4 containing the core tube 3.
[0015]
As shown in FIG. 1, the container body 4 is made of a flexible resin film material such as polyester. For example, two vertically long rectangular film materials are welded to the left and right side edges. A cylindrical body 5 is formed, and a substantially lemon-shaped film material is welded to the open upper surface and the open lower surface of the body 5, so that a substantially parallel first surface (upper surface in FIG. 1) 6 and second This is a pouch-type film bag having a surface (bottom surface in FIG. 1) 7. The film material to be the first surface 6 is provided with an opening slightly smaller than the inner diameter of the core tube 3 at the center, and this opening is sealed by bonding or welding a breakable sealing seal material 9. It has stopped.
[0016]
The core cylinder 3 functions as a core material, and as shown in FIG. 1, is a cylindrical body made of paper or plastic, and has a substantially rectangular opening elongated in the axial direction on the side surface near one end (the lower end in FIG. 1). 4 is opened by changing the phase by 90 degrees in the circumferential direction, and the hollow interior and the exterior communicate with each other through these openings 2.
[0017]
When the core cylinder 3 having the above-described configuration is provided inside the container body 4, one end where the opening 2 is opened is fastened (joined) to the substantially center of the second surface 7 by bonding or welding, and the other end Is fixed to the substantially center of the first surface 6, that is, at a portion opposite to the joining portion of the second surface 7 by adhesion or welding. At this time, the opening of the first surface 6 closed by the sealing material 9 is adjusted so that the opening is located in the hollow portion (opening region) of the core tube 3 and is fixed. When the core tube 3 is fixed inside the container body 4 in this way, the openings at both ends of the core tube 3 are sealed by the film material or the sealing seal material 9 constituting the container body 4, and the core tube 3. Two chambers 10a and 10b, an inner chamber 10a and an outer chamber 10b, can be formed.
[0018]
Then, as shown in FIG. 2, when the container 1 is stood so that the opening 2 of the core tube 3 is positioned above, in this state, the dry state is brought into one chamber, for example, the chamber 10 a inside the core tube 3. Can be separately stored in the other chamber, for example, the chamber 10b between the outer peripheral surface of the core tube 3 and the inner surface of the container body 4, whereby the glucose can be stored in another configuration. Can be stored isolated from ingredients. In order to fill with glucose and other components, the upper surface of the container body 4 and the core tube 3 is opened before the film material to be the second surface 7 is fastened (that is, the upper surfaces of the container body 4 and the core tube 3 are opened). Glucose and other components are filled from the opening at a level lower than that of the opening 2. And after this filling is complete | finished, the film material of the 2nd surface 7 is fixed and sealed.
[0019]
In this way, the interior space of the container 1 is partitioned by the core tube 3 with the opening 2 facing upward, and the sufficiently dry powdery glucose is stored in one chamber 10a, and in the other chamber 10b. When other components other than glucose are stored, glucose is isolated from electrolyte components such as sodium chloride, and does not change in quality even if transported or stored for a long period of time. As a result, it is not necessary to store glucose and other components other than glucose in separate containers 1, and the number of containers 1 used can be reduced. In addition, even if the container 1 vibrates during transportation, these filling amounts are appropriately adjusted in advance so that glucose and other components do not pass through the opening 2 and enter the adjacent room. Since each contained component is in the form of powder or granules, it does not mix even if there is some shaking during transportation.
[0020]
When the agent A is used, that is, when the agent A is dissolved, the top and bottom of the container 11 is reversed so that the opening 2 of the cylindrical body is placed downward. As shown in FIG. 3, the components are stored in the chambers 10a and 10b. Glucose and other components are both dropped into the lower portions of the respective chambers 10 a and 10 b by their own weight and mixed through the opening 2. Therefore, in this state, glucose and other components can be mixed and dissolved by the dissolving device as agent A.
[0021]
Specifically, as shown in FIG. 3, the container 1 is set on the turntable 11 of the melting apparatus with the opening 2 facing downward, and the connecting member 12 is placed on the container 1, that is, the core tube 3. . In this state, when the nozzle 13 penetrating the connecting member 12 is lowered, the cutter 14 provided at the tip of the nozzle 13 breaks the sealing material 9 and the nozzle 13 is inserted into the container 1, specifically into the core tube 3. The Even if the cutter 14 presses the sealing material 9 to break, the core tube 3 receives the pressing force at this time, and the container body 4 is hardly pressurized, so the container 1 is not crushed. Therefore, the insertion of the nozzle 13 is not hindered.
[0022]
In this way, when the nozzle 13 is inserted into the core cylinder 3, water is supplied from the nozzle 13 into the core cylinder 3, so that glucose in the core cylinder 3 is first dissolved by this water, and at the same time, Since the water supplied from the nozzle 13 descends in the core tube 3 and flows into the adjacent chamber 10b from the opening 2, other components filled in the chamber 10b are also dissolved. When the nozzle 13 is inserted until the lateral jet port 13 'of the nozzle 13 is almost the same height as the opening 2, and a thin water flow ejected from the jet 13' is pressed into the chamber 10b from the opening 2, The liquid in which the other constituent components are dissolved can easily flow backward from the opening 2, and the dissolution of the other constituent components in the chamber 10b can be promoted.
In this way, when glucose and other components are sufficiently dissolved and mixed in the water, the concentrated solution of Agent A overflows from the breakage opening of the sealing material 9 to the outside of the container 1 and is discharged from the drainage pipe 15. It is sent to the dilution device side. After that, it is mixed with the B agent solution and adjusted to a predetermined concentration to become a dialysate.
[0023]
In the present invention, since the core tube 3 is not crushed due to the force from above, the connecting member 12 can be pressed against the container 1 with a necessary and sufficient force. The liquid-tight state can be maintained. Therefore, it is possible to prevent the concentrated solution A from the container 1 from leaking outside.
[0024]
After the container 1 is used in this manner, the container body 4 is formed into a bag shape with a flexible resin film, so that it can be easily crushed to reduce the volume and discarded in this reduced volume state. can do. As a result, the waste capacity can be reduced.
[0025]
In the above-described embodiment, the opening of the end portion of the core tube 3 is sealed with the film material constituting the container body 4 and the breakable seal material 9, and the seal material 9 is broken to make the nozzle 13. If the film material itself constituting the container body 4 can be broken, both ends of the core tube 3 can be sealed with the film material of the container body 4. Good. In short, it is only necessary that the opening at the end of the core tube 3 is sealed by some means and one of them can be broken.
[0026]
Moreover, since the core tube 3 is indirectly in contact with glucose and other constituents for a long time, the core tube 3 may be subjected to a surface treatment so as to be more suitable for storing the medicine. The core tube 3 is sufficient if it has sufficient axial strength to receive the pressing force (generally about 25 to 27 kgf) when the nozzle 13 is inserted. Therefore, after use, the core tube 3 can also be crushed from the left-right direction to further promote volume reduction. And the core cylinder 3 is not limited to a cylindrical shape, For example, a cross-sectional ellipse shape or a rectangular cylinder may be sufficient. In this way, when the core cylinder 3 is formed into an elliptical or rectangular cylinder, it can be more easily crushed from the left and right directions, and volume reduction is further facilitated.
[0027]
In addition, in the case of this embodiment, if the opening part 2 is opened by the one end side surface of the core cylinder 3, a shape and number can be changed in design suitably.
[0028]
Further, the container 1 described above can be used even when the glucose is stored without being separated, that is, when the components of the agent A including glucose are mixed and stored. In this case, the agent A can be appropriately filled in the chamber 10a inside the core tube 3 and the chamber 10b outside the core tube 3, respectively, and can be conveyed or stored.
When glucose is not separated, the component in the chamber 10a and the component in the chamber 10b may be mixed. Therefore, the opening 2 opened on the side surface of the core tube 3 is not limited to one end, but the side surface. Any position may be used. Further, the core tube 3 may be sealed by joining one end to a part of the container body 3.
[0029]
And in the case of dissolution, the container 1 is set as it is in the dissolution apparatus, and when the nozzle 13 is inserted by the above-described operation, the water supplied from the nozzle 13 is also supplied to the chamber 10b through the opening 2, It can be dissolved without hindrance.
[0030]
After the container 1 is used in this manner, the container body 4 is formed into a bag shape with a flexible resin film, so that it can be easily crushed to reduce the volume and discarded in this reduced volume state. can do. As a result, the waste capacity can be reduced.
[0031]
【The invention's effect】
As described above, according to the present invention, the following effects can be obtained.
According to invention of Claim 1, a container is comprised by the core cylinder which provided the opening part in the side surface of one end vicinity, and the bag-shaped container main body which encloses this core cylinder, and the end of the said core cylinder is made into the container main body. A core cylinder is formed by sealing the opening at the one end by joining to a part, and sealing the opening at the other end by joining the other end of the core cylinder to a portion on the opposite side of the joint portion of the container body. Since the two chambers of the inner chamber and the outer chamber are formed and the region sealing the opening of the other end of the core tube is made of a breakable material , the container body is in a bag shape The pressing force when the container is set and the container is partially broken can be received by the core tube. Therefore, there is no possibility that the container main body will be crushed, and the container body can be smoothly broken without impairing the operability during melting.
And since the area | region which sealed the opening of the other end of a core cylinder is comprised with the material which can be fractured | ruptured, it can fracture | rupture smoothly and reliably.
Moreover, when discarding after use, the volume of the container can be reduced (volume reduction) by easily crushing the container body without using a special device. In addition, the core tube is not crushed in a state where it receives an axial pressing force applied when the sealing region is broken, and the pressing force from the left and right direction intersecting the axial direction is sufficient. Since the strength is set so that it can be crushed, even the core tube can be crushed from the left and right directions, and the volume can be further reduced.
[0032]
Further , one end of the core cylinder is joined to a part of the container body to seal the opening of the one end, and the other end of the other end of the core cylinder is joined to a part of the container body opposite to the joining part. Since the opening at the other end is sealed, the positional relationship between the core cylinder and the container main body is stabilized, so that the cutter can be inserted into a predetermined position when set in the melting apparatus.
[0033]
According to the invention of claim 2, a container is constituted by a core cylinder provided with an opening on a side surface near one end and a bag-like container body containing the core cylinder, and the openings at both ends of the core cylinder are sealed. Two chambers, an inner chamber and an outer chamber, are formed by stopping, and with the opening facing up, dry glucose is placed in one chamber and another configuration in the other chamber. Since the components are stored separately, glucose does not come into direct contact with other components during transportation and storage. Therefore, alteration of glucose can be prevented and it can withstand long-term storage.
Since the core tube can receive the pressing force when the container is set and the part of the container is broken, there is no risk of the container being crushed, and the container can be smoothly broken to impair the operability during melting. There is nothing.
Moreover, when discarding after use, the volume of the container can be reduced (volume reduction) by easily crushing the container body without using a special device. In addition, the core tube is not crushed in a state where it receives an axial pressing force applied when the sealing region is broken, and the pressing force from the left and right direction intersecting the axial direction is sufficient. Since the strength is set so that it can be crushed, even the core tube can be crushed from the left and right directions, and the volume can be further reduced.
[0034]
According to the invention of claim 3, the core tube is made of paper or plastic and the bag-like container body is made of a flexible resin film material. This can be done easily and reliably.
