DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a bag stand for holding a flexible bag such as an infusion bag, a dialysate bag, a blood bag, and a blood component bag.

[0002]

2. Description of the Related Art Prior to infusion of a patient, a solid or liquid drug such as a vitamin or an antibiotic is mixed and dissolved in an infusion solution in an infusion bag to prepare a drug solution. That is being done.

In this case, since the infusion bag is flexible, it does not stand upright by itself. Therefore, the infusion bag is suspended by a hanger or the like or supported, or placed in a state of being laid down. And the above-mentioned preparation work was performed.

[0004] However, when the infusion bag is suspended and supported by a hanger or the like, a hanger that takes a large space must be set, and the suspended portion is located on the bottom side of the infusion bag. A certain medicine co-injection port is located vertically below, and there is a problem that the preparation operation is difficult.

On the other hand, when the infusion bag is placed on a table or the like with the infusion bag folded down, the medicine injection port of the infusion bag is located near the upper surface of the table, and the upper surface of the table hinders the work. There is also a problem that the workability of the preparation operation is poor because the medicine injection port is easily moved due to the swing of the infusion solution in the inside. Further, when performing operations on a plurality of infusion bags, there is a problem that a large mounting space is required and the mounting place becomes messy.

In order to solve such a problem, Japanese Patent Publication No. 6-62259 and Japanese Patent Publication No. 6-36462 disclose a stand for holding an infusion bag upright.

However, in these stands, since the portion supporting the bottom of the infusion bag is horizontal (flat shape), the stability of holding the bag is poor, and the adverse effect of the bag bottom being significantly deformed is adversely affected. May occur.

In these stands, since the side plates do not cover the entire side surfaces of the bag, especially when the amount of liquid in the bag is large or when a kit for co-infusion of chemicals is mounted on the upper part of the bag. When the center of gravity of the bag is at a high position, for example, when the bag is folded, the bag may be bent and fall near the upper end of the side plate (in the middle of the bag).

[0009] Under such circumstances, there has been a demand for the development of a bag stand capable of holding the bag more stably.

[0010]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, a bag stand according to the present invention will be described in detail based on a preferred embodiment shown in the accompanying drawings.

FIGS. 1, 2, 3 and 4 are a front view, a left side view, a right side view and a top view, respectively, showing a first embodiment of a bag stand according to the present invention, FIGS. 5 and 6.
7 is a front view showing a use state of the bag stand of the present invention, FIG. 7 is a top view showing a connected state of the bag stand, and FIG. 8 is a front view showing the used state of the connected bag stand.

The upper side in FIGS. 1 to 3, 5, 6, and 8 is described as “upper end”, and the lower side is described as “lower end”.

As shown in FIGS. 1 to 4, the bag stand 1A of the present invention comprises a flexible bag 10 containing liquids such as infusions, dialysates, blood, blood components, and oral nutritional supplements. It is held almost upright.

Here, the structure of the bag 10 will be described first. The illustrated bag 10 is an infusion bag, and is formed by forming a flexible resin sheet such as soft polyvinyl chloride, ethylene-vinyl acetate copolymer (EVA), polyolefin, or polyester into a bag shape. It has a main body 11 and a co-injection port 13 formed at the upper end of the bag main body 11 and also serving as a discharge port (see FIG. 5).

The bag body 11 has a seal portion 12 formed by laminating resin sheets and fusing the periphery thereof by heat fusion, high frequency fusion, or the like. A liquid such as an infusion is stored inside the bag body 11. Examples of the infusion include physiological saline, electrolyte solution, Ringer's solution, high calorie infusion, glucose solution, water for injection, and the like, but are not limited thereto.

The co-injection port 13 is provided with a stopper made of an elastic material, and a needle tube is inserted through the stopper to suck (discharge) the liquid (infusion) in the bag 10 or inject the drug solution into the bag 10. Or you can.

Although the illustrated bag 10 is an infusion bag, the bag held by the bag stand 1A of the present invention is not limited to an infusion bag, but may be, for example, a bag for storing dialysate or its drainage, blood, or the like. The use and the type of liquid to be stored, such as a bag for storing blood components and a bag for storing oral nutritional supplements, are not particularly limited.

As shown in FIGS. 1 to 4, the bag stand 1A comprises a bottom plate 2, bottom holding members 3a and 3b for holding the bottom portion 14 of the bag 10, and a pair of plates for holding the side portions of the bag 10. And side-surface holding members 4a and 4b, which are integrally formed.

The side holding members 4a and 4b face each other at a predetermined angle, and are integrally connected to the bottom plate 2 at their lower ends, respectively, and have a U-shape that is open toward the upper end as a whole.

In this case, a bag storage space 5 for storing the bag 10 is formed between the side holding members 4a and 4b, and an insertion opening 51 for inserting the bag 10 into the bag storage space is formed at the upper end thereof. ing.

The inner surfaces of the side holding members 4a and 4b are surfaces that come into contact with the side surfaces of the bag 10, and are held by the side holding members 4a and 4b.
b, the distance between the inner surfaces of the insertion openings 5 from the bottom plate 2 side.
It is inclined so as to gradually increase toward 1 (upward). Thereby, the operation of inserting and storing the bag 10 into the bag storage space 5 from the insertion opening 51 is easy,
In addition, regardless of the size and the amount of liquid of the bag 10, the side surface of the bag 10 can be stably held by contacting the inner surface of the side surface holding members 4a and / or 4b.

Each of the side-side holding members 4a and 4b has a shape which covers the entire surface of the side surface of the bag 10, respectively.
It has dimensions. Thereby, regardless of the magnitude of the liquid amount in the bag 10, the medicine combination kit 1 shown in FIG.
Even for a bag 10 having a center of gravity at a relatively high position, such as the bag 10 with five, the bag body 11 can be effectively prevented from being bent or twisted, and can be stably held. Such prevention of the bag body 11 from being bent or twisted is particularly effective when a blood bag containing a separated component described later is held.

In the bag stand 1A, the front side and the rear side in FIG. 1 are open, so that the bag 10 can be inserted into the bag storage space 5 through this portion. Also, the side holding members 4a, 4a
Even when b is made of an opaque material, the bag 10 stored and held in the bag storage space 5 from this portion is
In particular, the state of the bottom portion 14 of the bag 10 can be visually recognized.

At the lower ends of the side holding members 4a and 4b, bottom holding members 3a and 3b projecting toward the bag storage space 5 are integrated with the side holding members 4a and 4b and the bottom plate 2, respectively. Is formed.

Each of the bottom holding members 3a and 3b has a pair of inclined surfaces 31 and 31 at its upper end, which are surfaces that contact the bottom 14 of the bag 10 and that are inclined at a predetermined angle with respect to the bottom plate 2. Have. The two inclined surfaces 31 constitute a substantially V-shaped receiving surface with which the bottom portion 14 of the bag 10 abuts. Thereby, the bag 10
, The deformation of the bottom 14 of the bag 10 is small,
That is, the bottom portion 14 of the bag 10 can be held in a shape corresponding to the shape (particularly a shape in a natural state).

Further, the bottom holding members 3a and 3b
It is located at a higher position, and can hold the bottom portion 14 of the bag 10 at a position higher than the lowermost position of the bag storage space 5. Thereby, a concave portion (groove) 6 as described below is formed.
Can be formed.

A concave portion (groove) 6 is formed between the bottom holding members 3a and 3b. When the bottom portion 14 of the bag 10 is held by the bottom holding members 3a and 3b, the seal portion 12 formed to protrude downward from the bottom portion 14 of the bag 10 is inserted into the concave portion 6. Therefore, the recess 6
Functions as an escape portion of the seal portion 12.

The recess 6 is formed continuously from the lowermost ends of the inclined surfaces 31, 31. Therefore, when the bag 10 is lowered from the insertion opening 51 and inserted into the bag storage space 5, even if the lower end of the seal portion 12 is slightly displaced in the horizontal direction in FIG. Bag 10
Is lowered, the lower end of the seal portion 12 is
1, slides down along the inclined surface 31 and is guided into the recess 6. Thus, when the bottom portion 14 of the bag 10 is held by the bottom holding members 3a and 3b, the seal portion 12 can be reliably guided (guided) into the concave portion 6 and inserted regardless of the state of the seal portion 12. . For this reason, the inclined surfaces 31 function as guiding means (guiding means) for guiding the seal portion 12 into the recess 6.

With the bottom holding members 3a and 3b configured as described above, the bag 10 can be stably held, especially when the bag 10 is inserted into the bag storage space 5.
Even without paying close attention to the storage operation, the bag 10 can be stably held without deformation of the bottom portion 14 and the seal portion 12.

More specifically, when the bag 10 is held, the weight of the bag 10 acts on the inclined surfaces 31, 31, and the bottom 14 of the bag 10 is pressed by the reaction. However, in the present embodiment, since the surfaces that the bottom 14 of the bag 10 abuts on are the inclined surfaces 31, 31, the pressure acting on the bottom 14 of the bag 10 is appropriately dispersed as compared with the horizontal plane, so that the bag 10 Of the bottom portion 14 is relatively small. Furthermore, since the seal portion 12 of the bag 10 is inserted into the recess 6 and escapes, the seal portion 12 is sandwiched and deformed (bending,
As a result, an irregular force acts on the bottom portion 14 of the bag 10 to prevent partial deformation (bending, twisting, etc.), pinholes, cracks, breakage, and the like of the seal portion 12. .

As described above, when the bag 10 is held,
That the deformation of the bottom portion 14 of the bag 10 is small,
In addition to being able to stably hold the bag 10, there are the following effects (advantages).

That is, for example, a blood bag containing each blood component separated into a plurality of blood component layers (eg, a plasma layer, a buffy coat layer, and a red blood cell layer) by centrifugation is held by the bag stand 1A. When one of the component layers (for example, supernatant plasma) is to be taken out from the blood bag, if the deformation of the bottom of the bag is large, the liquid swings in the bag and the interface between the adjacent component layers is formed. Disturbed,
Although the components are mixed with each other to reduce the recovery rate (increase in the percentage of leukocytes mixed into plasma), when the bag stand 1A of the present invention is used, as described above, the state before holding the bag 10 is used. On the other hand, since the deformation of the bottom portion 14 of the bag 10 after the holding is small, such inconvenience is eliminated or reduced. Also, for bags other than the blood bag, various inconveniences caused by the swinging of the liquid in the bag can be eliminated or reduced.

The angle of inclination of the inclined surfaces 31, 31 with respect to the horizontal plane is not particularly limited, but is usually 30 to 60 °.
Degree is preferable, and about 40 to 50 ° is more preferable.

The bottom plate 2, the side holding members 4a and 4b and the bottom holding members 3a and 3b are used for the bag 10 filled with the infusion.
When the steel sheet is held, it has sufficient strength to prevent significant deformation or breakage.

In this embodiment, the bottom plate 2 and the side holding members 4
a, 4b and the bottom holding members 3a, 3b are integrated,
In addition, the connecting portion (boundary portion) between the bottom plate 2 and the side holding member 4a and the connecting portion (boundary portion) between the bottom plate 2 and the side holding member 4b are deformed so as to protrude toward the bag storage space 5, thereby holding the bottom portion. The members 3a and 3b are configured. Therefore, the bottom holding member 3a reinforces the space between the bottom plate 2 and the side holding members 4a, and the bottom holding member 3b
It has a function of reinforcing between the side holding members 4b. Therefore,
Even when the bottom plate 2 and the side holding members 4a and 4b are made of a relatively thin plate or a low-strength material, necessary and sufficient strength can be ensured, which contributes to weight reduction and reduction in material cost. .

As shown in FIG. 1 to FIG.
Reinforcing ribs (reinforcing members) 91a and 91b are provided (integrally formed) on the upper outer surfaces of a and 4b, respectively. By providing these reinforcing ribs 91a and 91b,
When forming or using the bag stand 1A (particularly when holding the relatively heavy bag 10), it is possible to more reliably prevent the side holding members 4a and 4b from being bent (curved). That is, the original shape (flatness) of the side surface holding members 4a and 4b can be maintained, so that the connection with another bag stand 1A or the like described later can be easily and appropriately performed.

Further, near the end of the bottom plate 2 in the vertical direction in FIG. 4, reinforcing plates (reinforcing members) 92, 9 for connecting the side holding member 4a, the bottom plate 2 and the side holding member 4b, respectively.
3 are provided (integrally formed). This reinforcing plate 9
2 and 93, the positional relationship between the side holding members 4a and the side holding members 4b, particularly the angle formed by the side holding members 4a and 4b during molding and use of the bag stand 1A (see the above-described side holding member). An inclined state in which the interval between the inner surfaces of the members 4a and 4b gradually increases from the bottom plate 2 toward the insertion opening 51) can be maintained more reliably.

The reinforcing ribs 91a and 91b, the reinforcing plate 9
The conditions of the shape, installation position, installation direction, number of installation, and the like of the reinforcing members such as 2, 93 are not limited to those shown in the figure, and may be any. Further, such a reinforcing member may be formed by joining and fixing another member.

Further, such a reinforcing member is used for other purposes,
For example, each of the bottom plate 2, the bottom holding members 3a, 3b, and the side holding members 4a, 4b may be provided to reinforce the boundary portion or to reinforce (including maintaining the shape) the bottom holding members 3a, 3b themselves. .

Such a bag stand 1A has a connecting portion that can be connected to another bag stand (especially a similar bag stand).

That is, as shown in FIGS. 1 to 8, the connecting portion is formed by a fitting portion 7 provided at the upper end of the side holding member 4a.
a and a mating part 7b provided at the upper end of the side holding member 4b.

The fitting portion 7a includes a pair of hooks (locking portions) 7

Can be put together and the bag 10 can be easily arranged and managed, so that the work efficiency can be improved.

In particular, in the present embodiment, all the connected bag stands 1A are oriented in the same direction (arranged in parallel), so that the bags 10 stored and held are also the same. When the operation such as the chemical solution preparation operation is sequentially performed on each bag, the operation can be performed more easily, and the progress of the operation can be easily grasped.

When a plurality of bag stands 1A are connected, the contact area (the area of the contact surface of the bottom plate 2) increases, so that the posture stability of the bag stand 1A is further improved.

The structure of the connecting portion is not limited to the one shown in the drawing, and any structure may be used as long as it can connect or connect and fix the adjacent bag stands. )
Magnetic attraction, an adhesive sheet, a magic tape, or the like may be used.

In particular, when the connecting portion has the structure of the illustrated embodiment or the fitting structure of the hole and the projection, the positioning of the bag stands 1A can be performed simultaneously at the time of connection. That is, with respect to the positioning in the vertical direction, the bottom plates 2 of the connected bag stand 1A can be at the same height, and the work of adjusting the height with respect to the mounting surface (table top surface or the like) of the bottom plate 2 can be omitted. Therefore, it is preferable.

As shown in FIG. 6, such a bag stand 1A can hold the bag 10 having the medicine mixing kit 15 at the upper end.
