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.

  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 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 difference due to human error. In addition, there is a high risk that foreign matter such as dust, germs, and human hair adhering to the bag may be mixed when the automatic dissolving apparatus is introduced. Further, there are problems such as contamination of the periphery of the automatic melting apparatus due to dust generation at the time of charging or malfunction of the automatic melting apparatus.

  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 above-described circumstances, and its purpose is to facilitate the opening operation, and to automate the operation of charging the dialysis agent so that bacteria and dirt are mixed in the automatic dissolution apparatus. It is an object of the present invention to provide a bag-type dialysis agent storage container that can prevent inconveniences and can easily reduce the volume after use.

The present invention has been proposed in order to achieve the above object, and the one according to claim 1 is made of a flexible sheet material and includes a horizontally long bag body that can accommodate a dialysis agent therein.

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 dialysis agent storage container according to the present invention, and FIG. 2 is a bottom view.
The bag-type dialysis agent storage container 1 includes a horizontally long bag 2 made of a flexible sheet material, and support portions 3 provided at both ends of the bag 2.

The bag body 2 is formed by laminating, for example, PET (polyethylene terephthalate) vapor-deposited with silicon oxide or alumina, and forming a flexible synthetic resin sheet material (film material) excellent in moisture resistance and gas barrier properties into a horizontally long cylindrical shape. A predetermined amount of dialysis agent is accommodated inside and sealed by welding (or fusing) both left and right ends. At both left and right ends, support portions 3 for supporting the automatic melting apparatus are provided. This support portion 3 is configured by providing thick tongue-like members on the left and right ends of the bag body 2 and opening engagement holes 4 penetrating in the vertical direction in the tongue-like member.
The bag body 2 may be formed by stacking two flexible sheet materials having a strip shape on top and bottom, and welding (or fusing) the front and rear side edges and the left and right ends. Moreover, although the bag body 2 of this embodiment is formed in a size of about 10 cm in diameter and 60 cm to 70 cm in length, the volume and each dimension are appropriately set according to the amount of the dialysis agent used for preparing the dialysate. It is preferable to set.

  Further, the weakened portion 5 is formed in the width direction of the bag body 2 on the lower surface of the intermediate portion in the longitudinal direction of the bag body 2. The fragile portion 5 is configured by forming a slit cut to the middle of the thickness of the sheet material over the entire width of the bag body 2. Further, a protective member 6 made of a flexible sheet material having moisture resistance is attached to the surface of the fragile portion 5. This protective member 6 is a thin film made of a flexible synthetic resin sheet material (film material) excellent in moisture-proofing and gas barrier properties, for example, laminated with PET (polyethylene terephthalate) deposited with silicon oxide or alumina. Is formed in a size wider than the width of the bag body 2, and is attached so as to be able to be peeled off again while covering the fragile portion 5. Therefore, the bag body 2 is not torn during transportation and the internal dialysis agent does not leak out, and moisture does not permeate from the fragile portion 5 and the internal dialysis agent does not get wet. In addition, you may comprise the weak part 5 by forming the slit cut | disconnected over the thickness of the sheet | seat material over the full width of the bag body 2. FIG.

  The dialysis agent 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. Is done.

  Next, an operation when the dialysis agent storage container 1 is used in a hospital where artificial dialysis is performed will be described. First, at the time of use, that is, when a dialysis agent is introduced into an automatic dissolution apparatus (not shown), the protective member 6 is peeled from the bag body 2 to expose the fragile portion 5 and the fragile portion 5 is lowered. The hook 8 of the automatic melting apparatus is inserted from below into each engagement hole 4 in the state of being directed. Therefore, the dialysis agent storage container 1 is set in the automatic dissolution apparatus with the left and right ends supported by the hooks 8. Then, the set dialysis agent storage container 1 is transported to the charging position above the dissolution tank 9 by the movement of the hook 8, and stops when the fragile portion 5 is disposed immediately above the charging port 10 of the dissolution tank 9. If the dialysis agent storage container 1 is arranged, the dustproof cover 11 having a U-shaped cross-section is lowered from above, and the width direction front of the fragile portion 5 of the dialysis agent storage container 1 (the front side of the paper surface in the figure). Cover the rear (back side of the paper surface in the figure) and the top, and prepare so that the dialysis agent does not splash out of the dissolution tank 9 when the dialysis agent storage container 1 is opened. The dust-proof cover 11 is smaller than the insertion port 10, and an insertion opening 13 through which a pressing member 12 (described later) can be inserted in the vertical direction is opened at the top.

  Next, the pressing member 12 descends from above the dialysis agent storage container 1, and the distal end portion of the pressing member 12 passes through the insertion opening 13 of the dust-proof cover 11, and is opposite to the fragile portion 5 in the bag body 2. Is pressed downward (see FIG. 3). In addition, the hook 8 slightly moves outward in the left and right directions, applies a tensile force in the longitudinal direction to the dialysis agent storage container 1, and gradually moves upward in this state. Then, the dialysis agent storage container 1 is bent into a shallow V shape (see FIG. 4), and stress concentrates on the fragile portion 5 on the lower surface. Subsequently, when the hook 8 is raised while pressing the dialysis agent storage container 1 with the pressing member 12, the fragile portion 5 is broken, and the opening portion of the broken fragile portion 5 becomes a dialysis agent discharge port, and the bag The dialysis agent in the body 2 is charged into the charging port 10 of the dissolution tank 9. At this time, since the weakened portion 5 is not formed on the upper surface of the bag body 2, the dialysis agent storage container 1 is not separated into right and left. Then, when the hook 8 is moved further upward to increase the inclination angles on the left and right sides of the dialysis agent storage container 1, all of the dialysis agent in the bag body 2 flows down and is poured into the dissolution tank 9.

Thus, the dialysis agent storage container 1 can be easily opened, and the burden of the operation of introducing the dialysis agent into the automatic dissolution apparatus can be reduced. In addition, it becomes easier to automate the operation of charging dialysis agents, and there are inconveniences that dust and bacteria are mixed into dialysis agents and automatic dissolution equipment without manual opening work, and dust generation when dialysis agents are added. It is possible to prevent the worker from inhaling the dialysis agent. Further, since the fragile portion 5 is formed by a slit cut in the middle of the thickness of the sheet material, the dialysis agent storage container 1 can be more easily opened, and the efficiency of the dialysis agent charging operation is improved. be able to.
The pressing member 12 of the automatic melting apparatus is formed with a concave curved surface by matching the pressing surface formed at the tip with the surface of the bag body 2 so that the pressing surface and the surface of the bag body 2 can be in close contact with each other over a wide area. If it comprises, the concentrated load will not be added to the upper part of the bag body 2 at the time of a press. Therefore, it is preferable that the upper portion of the bag body 2 is not broken and the dialysis agent is scattered upward, and the pressing member 12 is not stained with the dialysis agent.
Moreover, since the weak part 5 used as the discharge port of the dialysis agent and the part of the bag body 2 pressed by the pressing member 12 are separated from each other, for example, the weak part 5 is connected to the automatic dissolution apparatus and the connection portion is sealed. However, the fragile portion 5 can be opened even in this sealed state. If the dialysis agent is discharged while this sealed state is maintained, it is possible to suppress contamination of foreign substances from the connecting portion between the dialysis agent storage container 1 and the automatic dissolution apparatus and dust generation of the dialysis agent.

  When all the dialysis agents fall and become empty, the empty dialysis agent storage container 1 supported by the hook 8 is conveyed to the removal position. Then, when the dialysis agent storage container 1 stops at the removal position, the left and right hooks 8 are turned upside down (see FIG. 5). Then, the engagement hole 4 is detached from the hook 8, the dialysis agent container is dropped, and is collected in the collection box below the removal position. In this manner, the hook 8 is hooked on the engagement hole 4 to support the dialysis agent storage container 1 and the carrier can be transported in this state. Moreover, after discharging the dialysis agent, the empty bag can be dropped by simply turning it upside down with the hook 8, and automation from the transportation of the dialysis agent storage container 1 to the collection of the empty bag can be easily realized. it can. Furthermore, the used dialysis agent storage container 1 can be crushed and flattened. Therefore, the used dialysis agent storage container 1 that has been emptied can be easily reduced in volume, and the disposal process can be facilitated.

  In the above-described embodiment, the support portion 3 is configured by opening the engagement hole 4. However, the present invention is not limited to this, and the dialysis agent storage container 1 is supported by the automatic dissolution apparatus. Any support unit 3 can be used as long as it can be easily attached and detached.

  Moreover, in the said embodiment, although the protection member 6 was formed in the magnitude | size which covers only the lower surface of the bag body 2 including the weak part 5, this invention is not limited to this. For example, the protection member is formed in a strip shape longer than the waist of the bag body 2, and the protection member is wound around the entire circumference of the bag body 2 in a detachable state to protect the fragile portion 5. Also good.

  Furthermore, the dust-proof cover 11 is not limited to the above-described one having a U-shaped cross section. For example, as shown in FIG. 6, it is a semi-cylindrical dust cover 14 formed on the inside with a curved surface that follows the surface of the bag body 2, bent into a shallow V shape, and the pressing member 12 can be inserted into the upper part. The thing which opened the appropriate insertion opening 15 may be used. In short, it covers the front, rear and top of the fragile portion 5 of the dialysis agent storage container 1 in the width direction, and prevents dust from splashing out of the dissolution tank 9 when the dialysis agent storage container 1 is opened. Any cover may be used.

  By the way, in the said embodiment, although the bag body 2 formed the synthetic resin sheet material in the cylinder shape, and comprised the support part 3 of the separate member on the both right and left sides of the bag body 2, this invention is not limited to this. . For example, the dialysis agent storage container 21 of the second embodiment shown in FIG. 7 forms a horizontally long tube by welding (or fusing) both ends of a rectangular synthetic resin sheet material (film material). Further, the open end of the cylinder is closed by welding (or fusion) to form the bag body 22. Further, the joint portion 23 formed on the body portion of the cylindrical bag body 22 is arranged in an upright state, and an automatic melting apparatus is provided at both left and right end portions (left end portion in FIG. 7) of the joint portion 23. An engagement hole 24 through which the hook 8 is inserted is opened. And in the corner part 25 of the right-and-left both sides (left side in FIG. 7) of the bag body 22, the sheet material superposed | superposed vertically is slanted (specifically, the bag body 22 side from the center of the edge part of the bag body 22). It is constructed so that the dialysis agent does not enter the corner 25 by welding or fusing (diagonally toward the portion). Accordingly, it is possible to prevent a problem that the dialysis agent remains in the corner 25 in the bag body 22 after the dialysis agent is introduced from the dialysis agent storage container 21 to the automatic dissolution apparatus.
