Description

  The present invention relates to a container for storing a dialysis agent such as a solid dialysis agent used for preparing a dialysate 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.
JP 2001-340447 A

Since the bag-type dialysis agent storage container is formed into a bag body with a flexible sheet material, like the container for infusion, there is an advantage that the bulk after use can be reduced. However, since the dialysis medical personnel manually open each bag one by one and put it into the automatic dissolution apparatus to prepare the dialysate, there is a risk of quantity differences due to human error. There is also a problem that there is a high risk of contamination of foreign matter such as airborne dust, dust adhering to the bag, human hair and the like.
When trying to set the bag-type dialysis agent storage container in the automatic dissolution apparatus, the bag body is crushed when opening with a cutter or inserting a nozzle because the shape of the bag body is unstable. . Even if the nozzle can be inserted, the sealed state of the joint between the nozzle and the bag body cannot be maintained. Therefore, when the solid dialysis agent is dissolved by supplying water from the nozzle into the bag body, Leaks, making it difficult to prepare dialysate.

On the other hand, if the bottle-type dialysis agent storage container is set in an automatic dissolution apparatus, the dialysate can be prepared fully automatically, and the risk of difference in quantity and contamination with foreign substances is lower than in the bag type. However, since the bottle type is composed of a material having higher rigidity than the bag type, there is a problem that even if it becomes empty after use, it is difficult to crush and reduce its capacity, and it becomes bulky when disposed as garbage.
Moreover, the bottle-type dialysis agent storage container generally has a configuration in which an opening serves as both an inlet and an outlet of the circulating fluid at one location. In this configuration, there is a problem in that it is difficult to stabilize the preparation of the dialysate because undissolved water tends to be generated because a water flow sufficient to dissolve the solid dialysis agent cannot be provided by the automatic dissolution apparatus.

  The present invention has been made in view of the above circumstances, and its purpose is to provide a dialysis agent storage container that can easily reduce the volume after use and can improve the solubility of the dialysis agent. It is something to try.

  The present invention has been made to achieve the above object, and the invention according to claim 1 is characterized in that a rigid penetrating member is vertically penetrated inside a bag body made of a flexible sheet material. The penetrating member projecting from the bag body is provided with an inlet at the upper end portion of the penetrating member protruding from the bag body and forming an inlet channel in the penetrating member communicating with the interior of the bag body. An outlet is provided at the lower end portion of the piercing member, and an outlet channel that communicates from the outlet to the inside of the bag body is formed inside the penetrating member, and the dialysis agent is stored inside the bag body. This is a dialysis agent storage container.

  According to a second aspect of the present invention, the penetrating member is composed of a cylindrical member having an inlet at an upper end portion and an outlet at a lower end portion, and a communication hole is formed on a side surface of the cylindrical member. The dialysis agent storage container according to claim 1.

  3. The dialysis agent storage according to claim 1 or 2, wherein a part constituting the bottom portion of the bag body is formed so as to be inclined downward toward the outlet channel side. Container.

  4. The dialysis machine according to claim 3, wherein the bag body is formed by inclining the shoulder portion of the bag body toward the penetrating member and can be used without distinction between the upper and lower sides. It is an agent storage container.

  According to a fifth aspect of the present invention, the penetrating member has a partition part that partitions the inlet channel and the outlet channel in the middle of the axial direction, and the inlet flow is formed on the side surface above the partition part. The dialysis agent storage container according to any one of claims 1 to 3, wherein a passage communication hole is provided and an outlet flow passage communication hole is formed in a lower side surface.

According to the present invention, the following specific effects can be obtained.
According to the first aspect of the present invention, the penetration member made of a rigid body is provided in the bag body made of the flexible sheet material so as to penetrate in the vertical direction, and the upper end portion of the penetration member protruding from the bag body is provided. In addition to providing an inlet, an inlet channel communicating from the inlet to the inside of the bag body is formed inside the penetrating member, an outlet is provided at the lower end portion of the penetrating member protruding from the bag body, and the inside of the penetrating member is provided. Since the outlet channel communicating from the outlet to the inside of the bag body is formed and the dialysis agent is accommodated inside the bag body, it is possible to ensure rigidity sufficient to receive pressure from above and below. This allows connection to an automatic melting device. Therefore, there is no need to manually open the bag body and put the drug into the automatic dissolution apparatus, making it easy to prepare dialysate, reducing the work burden on dialysis medical personnel, reducing the quantity and the risk of contamination. Can be reduced.
Further, when discarding after use, the bag body can be easily crushed without using a special device to reduce the volume (volume reduction).
Furthermore, since the inlet and the outlet are provided, the dissolution efficiency can be increased as compared with the conventional bottle type container.

  According to the second aspect of the present invention, the penetrating member is formed of a cylindrical material having an inlet at the upper end portion and an outlet at the lower end portion, and the communication hole is formed in the side surface of the cylindrical material. The introduced water can be distributed throughout the bag body. Therefore, it is possible to efficiently dissolve the dialysis agent in the bag and prepare a stable dialysis solution in a short time.

  According to the third aspect of the present invention, since the bottom of the bag body is inclined downward toward the outlet channel side, the dissolved dialysate can be smoothly guided to the outlet channel. Therefore, the dialysis agent hardly remains at the bottom of the bag.

  According to the fourth aspect of the present invention, the bag body can be used without distinction between the upper and lower sides because it is formed by inclining the shoulder portion of the bag body toward the penetrating member and can be used easily.

  According to invention of Claim 5, it has a division part which divides an inlet channel and an outlet channel in the middle of the inside of a penetration member, and has a communicating hole for inlet channels on the side surface above this division part. Since the outlet passage communication hole is opened on the lower side surface, the water supplied to the inlet surely flows into the bag body. Therefore, dissolution efficiency is further improved.

Hereinafter, embodiments of the present invention will be described with reference to the drawings.
FIG. 1 is a front view of a dialysis agent storage container according to the present invention, and FIG. 2 is a side view of the dialysis agent storage container. 3A is a front view of the penetrating member, FIG. 3B is a cross-sectional view taken along line AA of FIG. 3A, and FIG. 3C is a perspective view of the penetrating member. FIG. 4 is a front view of the dialysis agent storage container in a state set in the automatic dissolution apparatus, and the penetrating member lower end portion and the outlet side joining member are shown in a cross-sectional view.

The dialysis agent storage container 1 includes a bag body 2 that stores a solid dialysis agent, and a penetrating member 3 that vertically penetrates the inside of the bag body 2, and a penetrating member that protrudes upward from the bag body 2. 3 has an inlet 4 at the upper end portion and an outlet 5 at the lower end portion protruding downward.
In addition, in this embodiment, the said dialysis agent storage container 1 is comprised by the shape of up-down and left-right symmetry (refer FIG. 1).

  As shown in FIGS. 1 and 2, the bag body 2 is made of a flexible synthetic resin sheet material (film) such as a polyethylene film, and welds the left and right side edges of the stacked film materials. Moreover, the upper edges and the lower edges are welded and formed so as to sandwich the penetrating member 3 at the center. Further, the bottom portion of the bag body 2 is inclined downward so as to narrow down toward the penetrating member 3 as it goes downward, and the inclined bottom portion 6 is formed. Moreover, in this embodiment, the shoulder part of the bag body 2 is made to rise up and incline toward the penetrating member 3 and is formed into a vertically symmetrical shape so that it can be used without distinction between the upper and lower sides.

As shown in FIGS. 3 and 4, the penetrating member 3 is a cylindrical hollow member formed of a rigid material such as plastic or metal, and automatically melts the outer diameter of the portion projecting up and down of the bag body 2. A device (not shown) is molded into a shape and a size that match each of the upper connection member 7a and the lower connection member 7b, and the outer diameter of the intermediate portion enclosed in the bag body 2 is formed larger than the upper and lower small diameter portions. is there. Then, six substantially rectangular communication holes 8 that are elongated in the axial direction are formed on the side surface of the large-diameter portion by changing the phase by 60 degrees in the circumferential direction, and through these communication holes 8 from the inlet 4 to the bag body 2. An inlet channel 10 that communicates with the interior of the bag body and an outlet channel 11 that communicates from the outlet 5 to the interior of the bag body 2 are formed. Moreover, the joining part 9 joined to the bag 2 of the penetrating member 3 is formed in a boat-like flange shape. That is, the joining portion 9 has thick end flanges that have sharp ends at both ends that have an acute angle at the outer periphery, and that both side surfaces that connect the two sharp ends have a boat shape or an acute angle spindle shape as viewed from the top and bottom. It is shaped into a shape. When the penetrating member 3 having such a joint portion 9 is penetrated into the bag body 2 and joined to the upper and lower seal portions of the bag body 2, the seal portion of the bag body 3 is connected to the side surface of the boat-shaped joint portion 9. In addition, heat sealing is performed in a liquid-tight manner, and the positions are aligned so that the lower side of the communication hole 8 and the lowermost portion of the bottom of the bag body 2 have substantially the same height.
In the present embodiment, the penetrating member 3 is a cylinder in which an internal hollow portion penetrates vertically, and a vertically long communication hole 8 is formed on the side of the large diameter portion over almost the entire length of the large diameter portion. Therefore, there is no boundary between the inlet channel 10 and the outlet channel 11.

  The dialysis agent 12 is a powder or granule of a drug such as glucose, sodium chloride, magnesium chloride, or sodium bicarbonate, and a predetermined amount is stored in the bag 2 of the dialysis agent storage container 1. . In order to store the dialysis agent 12 in the bag body 2 of the dialysis agent storage container 1, for example, the upper edge of the bag body 2 is opened without sticking, and the bottom portion is joined to the penetrating member 3. In a state, a predetermined amount of the dialysis agent 12 is introduced into the bag body 2, and then the upper edges of the bag body 2 are joined together and joined to the penetrating member 3 and sealed. The inlet 4 and the outlet 5 of the penetrating member 3 are sealed by sticking a sealing material (not shown) for sealing. Therefore, when the dialysis agent 12 is stored in the dialysis agent storage container 1 and sealed, the dialysis agent 12 does not change in quality and can be stored and transported easily.

Next, operations and the like when using the dialysis agent storage container 1 in a hospital where artificial dialysis is performed will be described (see FIG. 4).
First, the sealing material for sealing the upper end surface and the lower end surface of the penetrating member 3 is peeled to open the inlet 4 and the outlet 5, and in this state, the lower end of the penetrating member 3 is placed in the upward recess of the lower connecting member 7b of the automatic melting apparatus. The penetrating member 3 is vertically sandwiched by fitting the upper connecting member 7a into the downwardly recessed portion of the upper connecting member 7a and bringing the connecting members 7a and 7b relatively close to each other. Further, when the penetrating member 3 is set in the automatic melting apparatus as described above, the penetrating member 3 penetrates into the flow paths of the connecting members 7a and 7b without peeling off the sealing material on the upper end surface and the lower end surface of the penetrating member 3. By providing each nozzle (not shown) protruding to the member 3 side, the sealing material for sealing may be broken at the tip of the nozzle, and the inlet 4 and the outlet 5 may be penetrated.
An O-ring 13 is provided as a sealing material in the recesses of both connection members 7a and 7b. When the penetrating member 3 is sandwiched from above and below by both connection members 7a and 7b, the upper inlet 4 is connected to the upper connection member 7a. The outlet 5 at the lower end is connected to the flow path 14 of the lower connection member 7b in a liquid-tight manner. In this way, even if the dialysis agent storage container 1 is set in the automatic dissolution apparatus and pressed by the upper and lower connecting members 7a and 7b and sandwiched, the penetrating member 3 has sufficient strength, so that it can buckle. In addition, the bag body 2 is not crushed because no pressure is applied thereto. Moreover, since the dialysis agent storage container 1 has a vertically symmetrical shape, it can be set in an automatic dissolution apparatus without distinguishing between the upper and lower sides and is easy to handle. For this reason, even if a medical worker misplaces the dialysis agent storage container 1 in the automatic dissolution apparatus, there is no possibility of adversely affecting the preparation of the dialysis agent.

  Then, when the automatic dissolution apparatus is operated to supply the solvent (water) from the upper connecting member 7a into the inlet 4, the water flows down the inlet channel 10 of the penetrating member 3 and passes through the communication hole 8 opened on the side surface to the bag. It flows into the inside of the body 2 and dissolves the dialysis agent 12. The solution obtained by dissolving the dialysis agent 12 returns to the hollow portion in the penetrating member 3 from the communication hole 8, that is, flows into the outlet channel 11, passes through the lower connecting member 7 b from the outlet 5, and enters the automatic lysis device. Supplied as When the dialysis agent 12 is filled into the bag body 2, it also enters the hollow portion of the penetrating member 3, so that the water supplied from the inlet 4 flows down through the hollow portion of the penetrating member 3 and exits from the outlet 5. However, the dialysis agent 12 is dissolved in the middle.

  If this operation is continued, the dialysis agent 12 in the bag body 2 is dissolved in sequence and supplied as a solution to the automatic dissolution apparatus, and the amount of the dialysis agent 12 in the bag body 2 gradually decreases. And even if the residual amount of the dialysis agent 12 decreases, the bottom of the bag body 2 is inclined in the present embodiment, so that it melts almost without remaining and is supplied to the automatic dissolution apparatus side. In addition, when the dialysis agent 12 in the bag body 2 is dissolved in water and decreases, the bag body 2 is crushed at atmospheric pressure as it decreases.

  In this way, when all the dialysis agent 12 in the bag body 2 has melted, the supply of water is stopped, and the upper and lower connecting members 7a and 7b are moved relatively up and down to widen the interval. If so, the dialysis agent storage container 1 which has been emptied is removed and discarded in a predetermined disposal place such as a collection box. At the time of disposal, since the bag body 2 has flexibility, it can be easily crushed and the volume of the entire container can be greatly reduced. Therefore, it does not become bulky at the time of disposal. Note that the penetrating member 3 is also hollow and has a communication hole 8 opened on the side surface, so that it is difficult to crush in the axial direction, but it can be deformed when pressed from the side surface, and the bulk can be further reduced.

The dialysis agent storage container 1 ′ shown in FIG. 5 is different from the above embodiment in the penetrating member 3 ′, and other parts are the same as in the above embodiment. For this reason, a different structure is demonstrated, the same code | symbol is attached | subjected about the same part and description is abbreviate | omitted.
The penetrating member 3 ′ is provided with a partition portion 17 that divides the upper half and the lower half in the middle of the hollow portion, and has an inlet flow passage communication hole 8 a on the side surface above the partition portion 17. An outlet channel communication hole 8b is formed on the side surface. Therefore, when this penetrating member 3 ′ is attached in a state of vertically penetrating the bag body 2, an inlet channel 10 communicating from the inlet 4 to the inside of the bag body 2 is formed through the inlet channel communication hole 8 a, An outlet channel 11 communicating from the outlet 5 to the inside of the bag body 2 is formed through the outlet channel communication hole 8b.

  In the dialysis agent storage container 1 ′ having the penetrating member 3 ′ having such a configuration, as in the case described above, the dialysis agent storage container 1 ′ is set in the automatic dissolution apparatus and pressed and clamped by the upper and lower connecting members 7 a and 7 b. However, no force is applied to the bag body 2 due to the penetrating member 3 ′ receiving this pressure. Then, when water is supplied into the inlet 4 from the upper connecting member 7a by operating the automatic melting apparatus, the water flows down the inlet channel 10 formed in the upper half of the penetrating member 3 'and opens to the side surface. The dialysis agent 12 is surely flown into the bag body 2 through the flow passage communicating hole 8a and the dialysis agent 12 is dissolved, and the dissolved solution of the dialysis agent 12 passes through the outlet flow passage communicating hole 8b in the lower half of the penetrating member 3 '. The outlet flow path 11 formed in the above is flowed down and supplied from the outlet 5 through the lower connecting member 7b to the automatic dissolution apparatus as a dialysate.

  Thus, in this embodiment, it is possible to prevent the water supplied from the inlet 4 from flowing out from the outlet 5 as it is by the partitioning portion 17, and the penetrating member 3 ′ is always transmitted from the inlet channel communication hole 8 a. In other words, the water supplied to the inlet 4 surely flows into the bag body 2 and dissolves the dialysis agent 12. For this reason, dissolution efficiency can be further improved.

  Further, the inlet channel communication hole 8a may be set smaller than the long, substantially rectangular shape exemplified in the above embodiment. Thereby, the flow velocity of the water which flows into the inside of the bag body 2 from the communicating hole 8a for inlet channels can be raised. Therefore, the stirring effect when the water supplied to the inlet 4 flows into the inside of the bag body 2 can be enhanced, whereby the dissolution efficiency can be further enhanced.

  In addition, the flexible sheet material which comprises the bag body 2 is not limited to the above-mentioned polyethylene film, Other resin sheets may be sufficient, and the composite material which vapor-deposited silica (silicon dioxide) may be sufficient. The dialysis agent 12 stored in the bag 2 is not limited to the above, and may be a gel type, a liquid type, or the like, and can be appropriately selected.
