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: bag type and 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, similarly to the drip liquid container, there is an advantage that the bulkiness after use can be reduced. However, since dialysis workers manually open each bag one by one and put it into the dissolution apparatus to prepare the dialysate, there is a risk of mistakes in adding agent A and agent B and mistakes in quantity due to human error. There is. In addition, it is said that there is a high risk that the dialysis agent will not flow out of the bag smoothly when the dissolution apparatus is inserted, and foreign substances such as dust, germs, and human hair adhering to the bag will be mixed. There's a problem. Furthermore, there are problems such as contamination of the periphery of the melting apparatus due to dust generation at the time of charging, or malfunction.

  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 is made 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.

  The present invention has been made in view of the circumstances described above, and its purpose is to cover the part connected to the dissolution apparatus until just before setting (use) and reliably prevent bacteria and dirt from being attached. In some cases, a bag-type dialysis agent storage container is provided in which air can surely enter the bag and the dialysis agent flows out smoothly, and its volume can be easily reduced after use.

The present invention has been proposed in order to achieve the above-mentioned object, and the one according to claim 1 seals the upper end opening of a cylindrical body made of a flexible sheet material and is close to the lower end opening. A bottom portion made of a flexible sheet material is provided inside the trunk portion, and a space surrounded by the bottom portion, the trunk portion, and the sealing portion at the upper end is used as a dialysis agent storage empty portion, and the trunk is positioned below the bottom portion. Sealing the lower end opening of the part and covering the outer surface of the bottom part,
The bottom portion is characterized in that a hole having a size that prevents passage of the dialysis agent stored in the dialysis agent storage space but allows passage of air is provided.

  According to a second aspect of the present invention, there is provided the dialysis agent storage container according to the first aspect, wherein the holes are constituted by perforated holes opened at a predetermined interval. .

  According to a third aspect of the present invention, there is provided the dialysis agent storage container according to the first aspect, wherein the hole is constituted by a plurality of holes arranged in a staggered pattern.

  In a fourth aspect of the present invention, the hole diameter of the hole is 30 to 200 μm, and the hole area ratio is 0.1 to 2.5%. It is a dialysis agent storage container as described.

  According to a fifth aspect of the present invention, the lower end portion of the trunk portion can be cut between the sealing portion at the lower end and the bottom portion, and the outer surface of the bottom portion is exposed in the lower end opening of the trunk portion in the cut state. The dialysis agent storage container according to any one of claims 1 to 4, wherein the dialysis agent storage container is formed.

According to the present invention, the following excellent effects can be obtained.
According to the first aspect of the present invention, the upper end opening of the cylindrical body portion made of the flexible sheet material is sealed, and the bottom portion made of the flexible sheet material is provided inside the body portion close to the lower end opening. The space surrounded by the bottom part, the body part and the sealing part at the upper end is used as a dialysis agent storage empty part, and the lower end opening of the body part located below the bottom part is sealed to seal the outer surface of the bottom part. Since the cover is concealed, in this sealed state, there is no inconvenience that the dialysis agent in the inside gets wet even if a hole through which air passes is open at the bottom. Then, when the seal is released by cutting off the lower end portion of the body portion between the sealing portion at the lower end and the bottom portion, the outer surface of the bottom portion is exposed in the lower end opening, and is set in the dissolving device in this state. Then, if the bottom is opened with a cutter or the like, the internal dialysis agent can be put into the dissolution apparatus.
Thus, since the bottom part which is a connection part to a melting | dissolving apparatus is sealed and covered until it is used, it can maintain a clean state reliably. Therefore, it is possible to eliminate the inconvenience that dust and bacteria adhering to the container are mixed into the dissolving device when it is put into the dissolving device, and the dialyzer is dropped by breaking the bottom in the state set in the dissolving device. Dust generation can be suppressed.
Furthermore, since a hole of a size that prevents the passage of the dialysis agent stored in the dialysis agent storage empty space but allows the passage of air is opened at the bottom of the container, the bottom hole in the state connected to the dissolution apparatus Through this, external air surely enters the container, so that the dialysis agent can smoothly flow out from the breakage opening at the bottom. Since the dialysis agent does not pass through the bottom hole, there is no inconvenience that the dialysis agent spills out of the hole and contaminates the surroundings. The used container that has been emptied after being charged can be easily reduced in volume by, for example, crushing, and the disposal process can be facilitated.

  According to the second aspect of the present invention, since the bottom hole is composed of a plurality of perforated holes opened at a predetermined interval, when the bottom part is broken, it breaks along the perforation. It becomes easy to do. Therefore, even if the cutting of the cutter that opens the bottom is somewhat lowered, it can be reliably opened.

  According to the third aspect of the present invention, since the bottom hole is composed of a plurality of holes arranged in a staggered pattern, the bottom part is easily broken in the other direction, and is set in a melting device and the bottom part is cut by a cutter. It can be broken more easily and reliably.

  According to the fourth aspect of the present invention, the hole diameter is 30 to 200 μm, and the hole area ratio is set to 0.1 to 2.5%. Thus, the smooth outflow of the dialysis agent can be ensured and the passage of the dialysis agent can be reliably prevented.

  According to a fifth aspect of the present invention, the lower end portion of the trunk portion can be cut between the sealing portion at the lower end and the bottom portion, and the outer surface of the bottom portion is exposed in the lower end opening of the trunk portion in the cut state. As a result, the bottom can be exposed by a simple operation when set in the dissolution apparatus, and the handling is easy.

DESCRIPTION OF EXEMPLARY EMBODIMENTS Hereinafter, the best embodiment of the invention will be described with reference to the drawings.
FIG. 1 is a front view of a first embodiment of a bag-type dialysis agent storage container, FIG. 2 is a front view of a state where a lower end portion of a trunk portion of the bag-type dialysis agent storage container shown in FIG. 3 is an enlarged plan view of the bottom hole (parallel type), FIG. 4 is an enlarged plan view of the bottom hole (square staggered type), and FIG. 5 is a perspective view of the bag-type dialysis agent storage container as seen from obliquely below. is there.

  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. The bottom 3 is provided with a hole 4 having a size that prevents passage of the stored dialysis agent but allows passage of air. 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 2a. . Also, a substantially spindle-shaped sheet material in plan view that is bent in a bowl shape or 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 2 a 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. In addition, if the lower end opening of the trunk | drum 2 is sealed, the sheet material which comprises the bottom part 3 will be pinched | interposed into the film material of the both sides which comprise the trunk | drum 2, and it will be bent a little or a wrinkle. There is no problem at this stage.

  And when using it, that is, when throwing it into the melting device, the lower end portion 8 of the body portion 2 can be cut between the sealing portion 2b and the bottom portion 3 at the lower end, and the outer surface of the bottom portion 3 in the cut 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 hole 4 opened in the bottom portion may be any small hole as long as it prevents passage of the dialysis agent 10 accommodated in the dialysis agent storage cavity 6 but allows passage of air. As for the arrangement of the holes 4, for example, as shown in FIG. 3, a plurality of perforated holes 4 are formed with a predetermined interval HP, and the perforated holes 4 are formed with a predetermined interval LP. It may be arranged in multiple rows in parallel. In this way, when a plurality of holes 4 are formed in a perforated shape, the perforated portion becomes a linear weakened portion, and it is easy to break from the weakened portion, and even with a cutter with reduced sharpness, it is ensured. Break. Further, the holes 4 are not limited to a plurality of holes arranged in parallel in a perforated shape, and the interval HP and the interval LP may be set to the same size and arranged in a lattice shape, as shown in FIG. Further, the interval p between the vertical perforation holes 4 and the interval p between the horizontal perforation holes 4 are set to the same size, and intersects the perforation holes 4 at an angle of 45 degrees. A square zigzag type in which a plurality of holes 4 are provided at the intersections between the inclined lines may be provided.

And these holes 4 ... are 30-200 micrometers in pore diameter from the particle diameter of the dialysis agent 10 calculated | required that it melt | dissolves easily, and a porosity is 0.1-2.5%. It is desirable that This is because, even if the dialysis agent 10 is a granule, if it is 200 μm or more, it passes through the holes 4, and if it is 30 μm or less, the passage of air becomes insufficient. Further, even when the hole area ratio is 0.1% or less, the passage of air becomes insufficient, and when it exceeds 2.5%, the production is difficult.
The hole area ratio can be expressed by 157 × D ² / p ² in the case of the square staggered type shown in FIG.

  Moreover, although the range which opens the hole 4 may be the whole area of the bottom part 3 or may be a part, the range which opened the plurality of holes 4 not only functions as a simple ventilation area but also functions as the fragile part. Therefore, it is desirable to arrange at least in the center part of the bottom corresponding to the cutter of the melting apparatus.

  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 volume 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 volume of the dialysis agent storage container 1 for agent B is about 1 liter (width of about 13 cm, The height is set to about 23 cm) so that the dialysis agent storage container 1 can be identified only by looking.

Next, the usage method will be described.
In a state where the factory is shipped, a predetermined amount of dialysis agent 10 is stored in the dialysis agent storage space 6, the lower end opening of the body 2 is sealed, and the lower surface of the bottom 3 is covered by the lower end 8 of the body 2. Covered. In this state, it is transported to the hospital and stored. Then, when used, that is, when the dialysis agent 10 is introduced into the dissolution apparatus, first, as shown in FIG. 2, first, the barrel is placed between the sealing portion 2 b at the lower end of the barrel 2 and the bottom 3. The lower end portion 8 of the part 2 is excised. At this time, a tool such as a scissors or a cutter may be used. However, if a triangular notch 11 is formed in advance in the sealing portion 2c on the side edge of the body portion 2, the operator can manually perform this notch. The lower end portion 8 of the body 2 can be excised by tearing from the body 11. When the lower end portion 8 of the body portion 2 is cut in this way, the bottom portion 3 which is bent by opening the lower end of the body portion 2 can be developed and the outside thereof can be exposed in the lower end opening, and the bottom portion 3 is filled. The wrinkles etc. are stretched by the dead weight of the dialysis agent, and stretched into a bowl shape.

  When the bottom 3 is exposed, the dialysis agent storage container 1 is set in the dissolving device. Since the dialysis agent storage container 1 in the present embodiment has a hole as a hanging part 5 at the upper end, a hanger (not shown) of a dissolution apparatus is inserted into the hole and suspended. The suspended dialysis agent storage container 1 is transported to the charging position above the dissolution tank by the movement of the hanger. In this charging position, as shown in FIG. 5, the melting tank (not shown) of the melting apparatus is raised, and the cutter 12 provided at the upper part of the melting tank comes into contact with the lower surface of the bottom part 3 from below to form the bottom part. Break 3 The bottom portion 3 has a lower strength than the body portion 2 and is easily torn because a plurality of holes 4 are formed. For this reason, the cutter 12 can be easily broken simply by contacting and pressing the cutter 12 against the bottom 3. Then, if the bottom 3 is broken, the cutter 12 is further raised and then lowered. Then, the broken piece of the broken bottom portion 3 bends downward to open the mouth around the cutter 12, and the dialysis agent 10 in the dialysis agent storage empty portion 6 starts to fall from the opening. In this way, when the dialysis agent 10 inside begins to flow out, the pressure in the dialysis agent storage space 6 decreases. Then, since a plurality of holes 4 are opened in the bottom portion 3, external air flows into the dialysis agent storage space 6 through these holes 4 and attempts to return the internal atmospheric pressure to atmospheric pressure. Therefore, the balance between the pressure in the dialysis agent storage space 6 and the external atmospheric pressure is maintained, so that the dialysis agent in the dialysis agent storage space 6 flows out smoothly without stagnation and dissolves. It is put into the tank.

  And when all the dialysis agents fall and become empty, the empty dialysis agent storage container 1 suspended on the hanger is transported to the removal position. In this way, the used dialysis agent storage container 1 is crushed into a flat bag, and the volume is reduced to a minimum. Therefore, when discarding, it is easy to carry.

  In this way, 9 A (liter) A stock solution was prepared by adding A agent into the dissolving bath for A agent, and 11.34 L of B stock solution was prepared by introducing B agent into the dissolving bath for B agent. To do. And if it mixes by the ratio of A stock solution: B stock solution: water = 1: 1.26: 32.74, 315L dialysate can be prepared.

  In addition, although the suspending part 5 in the above-described embodiment is a horizontally long hole, the present invention is not limited to this, and it is sufficient that the dialysis agent storage container 1 can be suspended from the dissolution apparatus. For example, it may be formed in a hook shape.

  In the above embodiment, the agent A is a drug containing components such as glucose, sodium chloride, and magnesium chloride, and the agent B is a drug mainly composed of sodium hydrogen carbonate, but the present invention is limited to this combination. First, a combination of drugs dissolved in a liquid such as water can be prepared by preparing a predetermined dialysate, and it is preferable to separate them during transportation and storage.

  And this invention is not limited to the capacity | capacitance and ratio of an above-mentioned dialysis agent, The dimension and storage capacity | capacitance of a dialysis agent storage container are suitably set according to the usage-amount of the dialysis agent required for preparation of a dialysate. It is preferable.

Moreover, in the said embodiment, although sealed by welding the lower end of the trunk | drum 2, you may seal by bonding with an adhesive tape.
Furthermore, although the said container comprised the bottom part using the synthetic resin film material, the bottom part in this invention is not limited to this, It consists of a flexible sheet material, and is accommodated in the dialysis agent storage empty part. Any material can be used as long as it has a hole size that prevents the passage of the dialysis agent, but allows the passage of air, and the hole is not limited to a hole drilled by post-processing. Good. For example, it may be a non-woven fabric (including a filter shape, a Japanese paper style, a Tyvek sheet shape, or the like), or may be a stretched film such as Gore-Tex provided with a tear. When the bottom portion is made of such a material, the hole area ratio is large even if the hole is small, and it is suitable as a dialysis agent container. And the hole quoted in the said embodiment may be opened separately in the bottom part using these raw materials.
