Description

FLEXIBLE CONTAINER FOR MEDICAL USE AND NUTRIENT SUPPLY SYSTEM USING SAME}

The present invention relates to a medical soft container and a nutrition supply system using the same.

Enteral nutrition or intravenous nutrition is known as a method of administering nutrition or drugs to a patient without oral. In enteral nutrition, liquids such as nutrients, fluids or drugs are administered through a tube passed from the nasal cavity of the patient to the stomach or duodenum. In the intravenous nutrition method, a liquid substance (generally referred to as "sap") containing a nutrient component such as glucose and / or a pharmaceutical component is administered through the infusion circuit inserted into the vein of the patient.

When enteral nutrition or intravenous nutrition is performed, it is necessary to inject the liquid to be administered to the patient into an empty medical soft container in advance.

FIG. 17 is a front view showing a schematic configuration of an example of a conventional medical soft container 900, and FIG. 18 opens the medical soft container 900 shown in FIG. 17, and opens the opening 922 at its upper end with one hand. Fig. 19 is a view showing a state in which the opening 922 is opened by holding, and Fig. 19 is a view showing a state in which a liquid substance is injected into the medical soft container 900 shown in Fig. 17.

The medical soft container 900 includes a receiving portion 921 for accommodating a liquid substance and a discharge port 930 having a through hole for taking out the liquid substance contained in the accommodating portion 921. The accommodating part 921 is a bag-shaped object formed by laminating two flexible sheets with each other and joining their outer peripheral edges together by a heat seal (heat bonding). The discharge port 930 is made of a resin material that is relatively hard as compared with the sheet constituting the receiving portion 921.

Injection of the liquid substance into the empty medical soft container 900 is performed as follows. First, the notch 928 is used as a starting point, and the upper portion of the opening 922 is cut and opened along the cut line 929 to release the zipper 923. Next, as shown in FIG. 18, the opening part 922 is opened, holding the outer edge of the opening part 922 with one hand. Next, as shown in FIG. 19, the other hand (not shown) picks up the container 998 containing liquid substance, such as a medicine and a nutrient, and puts the liquid substance in the accommodating part 921 from the opening part 922. Inject.

Japanese Patent Publication No. 2007-314245

However, in the conventional liquid injection operation into the medical soft container 900, the outer edge of the opening 922 is gripped with one hand, the opening 922 is opened, and the medical use is performed from the start to the end of the injection operation of the liquid. The soft container 900 must be maintained. As the amount of injected liquid increases, the weight of the medical soft container 900 gradually increases. On the other hand, since the medical soft container 900 includes the opening 922 and is made of a flexible material, the opening 922 simply deforms when a large gripping force is applied. Accordingly, the medical soft container 900 may be dropped, or the opening 922 may not be sufficiently opened, resulting in spilling the liquid. As described above, the operation of injecting the liquid into the conventional medical soft container 900 has a large mental and physical burden on the worker.

Therefore, it is preferable to provide the member which can stably hold a medical soft container in the state which opened the opening in the medical soft container.

However, since the sheet constituting the medical soft container is generally low in mechanical strength, when such a member is provided, it is preferable that stress concentration does not occur due to the opening / closing operation of the opening or the weight of the injected liquid. Moreover, it is necessary to avoid deterioration of the quality of the medical soft container by providing such a member.

An object of the present invention is to provide a high quality medical soft container which can be stably maintained in a state in which an opening is largely opened during a liquid injection operation, and where stress concentration hardly occurs. Moreover, an object of this invention is to provide the nutrition supply system provided with such a medical soft container.

In the medical soft container of the present invention, at least two flexible resin sheets are bonded to each other, and a flexible bag member having an opening that can be opened and closed at an upper end thereof, a discharge port provided at a lower end of the flexible bag member, and a finger inserted therein. A pair of opening and closing operation portions provided on the flexible bag member by loosening the central portion thereof so as to form a possible insertion path is provided. At least one end portion of at least one of the upper and lower sides of the pair of opening and closing operation portions is fixed to the outer surface of the flexible bag member by a heat seal. The heating region at the time of fixing the at least one end portion by the heat chamber includes the entirety of the end edges of the at least one end portion, and is further provided at the intersection of the outer circumferential edge of the heating region and side end edges on both sides of the opening and closing operation portion. Thus, the outer peripheral edge is inclined with respect to the longitudinal direction of the opening and closing operation portion.

The nutrition supply system of this invention is equipped with the said medical soft container of this invention.

According to the present invention, by inserting a finger into the insertion path formed by a pair of opening and closing operation unit provided in the flexible bag member, it is possible to stably maintain the medical soft container in the state of opening the opening.

Moreover, since the heating area at the time of fixing the edge part of an opening-closing operation part by a heat chamber includes the whole edge edge of the said edge part, the edge edge adheres closely to a soft resin sheet. Therefore, by providing an opening / closing operation part, the touch and external appearance do not fall, and the fall of the quality of a medical soft container can be prevented.

Moreover, in the intersection of the outer peripheral edge of a heating area | region, and the side edge of the opening / closing operation part, the outer peripheral edge is inclined with respect to the longitudinal direction of an opening / closing operation part. Therefore, when the external force which isolates a center part from a flexible bag member acts on the center part of an opening-and-closing operation part, it can prevent that a big stress concentration arises at the said intersection.

In the present invention, at least one of the ends of the opening and closing operation portion fixed to the flexible bag member by the heat chamber satisfies the following two conditions.

First, the heating area at the time of fixing an edge part by a heat chamber includes the whole edge of the said edge part (henceforth "a 1st condition"). Here, the heating region "comprises" the entirety of the terminal edge means that the entirety of the terminal edge is present in the heating region (including the case where a part of the terminal edge is located on the outer peripheral edge of the heating region). Preferably, it means that the entirety of the terminal edge is not in contact with the outer circumferential edge of the heating area, but is located inside the outer circumferential edge.

Secondly, at the intersection of the outer circumferential edge of the heating area and the side end edges on both sides of the open / close operating portion, the outer circumferential edge is inclined with respect to the longitudinal direction of the open / close operating portion (hereinafter referred to as “second condition”). Here, in the said intersection, the said inclination edge | side is "inclined" with respect to the longitudinal direction of the opening-closing operation part, It means that the direction of the tangential of the outer periphery edge in an intersection is neither parallel nor perpendicular to the longitudinal direction of the opening-and-closing operation part. . The longitudinal direction of an opening / closing operation part means the direction which connects the upper and lower ends fixed to the flexible bag member of an opening / closing operation part.

In this invention, it is preferable that the said heating area has a line segment which connects the substantially circular arc and the both ends of the said substantially circular arc, and the said substantially circular arc cross | intersects the said side edge of the said opening-closing operation part. Thereby, even if the external force of any direction, such as separating a center part from a flexible bag member, acts at the center part of an opening-and-closing operation part, not only the intersection of the outer peripheral edge of a heating area | region and the side end edge of an opening / closing operation part, The occurrence of stress concentration can be prevented.

Alternatively, the heating region may have a substantially trapezoidal shape, and the substantially trapezoidal quadrilateral may cross the side edge of the opening / closing operation portion. Thereby, since the shape of the metal mold | die used at the time of a heat chamber becomes simple, a metal mold | die can be created easily.

The pair of opening and closing operation portions may be formed as a member separate from the flexible resin sheet constituting the flexible bag member. In this case, it is preferable that the upper end and the lower end of each of the pair of opening and closing operation portions are fixed to the outer surface of the flexible bag member by a heat seal.

In the above, the upper end portion of each of the pair of opening and closing operation portions is fixed to the outer surface of the flexible bag member by a heat chamber heated in a heating region that satisfies the first condition and the second condition. desirable. Thereby, large stress concentration can be prevented from occurring at the upper end part where a large force often acts.

Alternatively, each of the pair of opening and closing operation units may be integrally formed with the flexible resin sheet constituting the flexible bag member. In this case, it is preferable that the lower end part of each pair of opening / closing operation parts is fixed to the outer surface of the said flexible bag member by a heat seal. Thereby, since the edge part of the upper side of the opening / closing operation part with which a large force acts in many cases is created integrally with a flexible resin sheet, the connection strength of the opening-and-closing operation part and soft resin sheet in the said edge part improves.

And a connector 95 provided at the other end of the flexible tube 92, a connector cover 96 covered with the connector 95, and the like. The dropping vessel 93 visualizes the flow rate of the liquid flowing through the fluid set 91. The flow rate regulator 94 pressurizes the flexible tube 92, changes its flow path cross-sectional area, and enables the flow rate adjustment of the liquid substance flowing through the fluid set 91. The connector 95 is connected to a tube (not shown) inserted into the nasal or vein of the patient. However, the nutrition supply system of this invention is not limited to the structure shown in FIG. 4, For example, the nutrition supply system is combined with the medical soft container 1 of this embodiment by combining arbitrary sap sets known conventionally. You may comprise.

Initially, the flow regulator 94 is operated to press and crush the flexible tube 92 to close the flow path. In this state, as shown in FIG. 5, the thumb of a left hand is inserted into the insertion path 45a of the opening-closing operation part 40a, and the other finger of the left hand is inserted into the insertion path 45b of the opening-and-closing operation part 40b (in FIG.

In this embodiment, the heating area 53a, 53b contains the whole edge edge 48a, 48b on the opposite side to the center part 41a, 41b of the opening-closing operation part 40a, 40b (1st condition). Moreover, the intersection point P13a, P13b of the outer peripheral edge of the heating area 53a, 53b (approximately circular arc 53a1, 53b1 in this embodiment) and the side edge edge 46a, 46b of the both sides of the width direction of the opening-closing operation part 40a, 40b. WHEREIN: The outer periphery edge (circular arc 52a1, 52b1) of the heating area | region 52a, 52b is inclined with respect to the longitudinal direction (in this embodiment direction of the central axis 1a) of the opening-closing operation part 40a, 40b ( Second condition).

The effects of the upper and lower ends 42a, 42b, 43a, 43b of the opening and closing operation portions 40a, 40b being heat-sealed by the above-described heating zones 52a, 52b, 53a, 53b will be described below.

For comparison, an example in which the upper end portion 42a of the opening and closing operation portion 40a is fixed to the flexible resin sheet 20a by the heat seal in a heating region different from the present invention is shown in FIGS. 9A and 9B.

The heating area | region 102a shown in FIG. 9A has a substantially rectangular shape arrange | positioned inside the edge edge 48a and the side edge edge 46a, 46b of the upper end part 42a of the opening-closing operation part 40a. Therefore, unlike the heating area of this embodiment, this heating area | region 102a does not contain the terminal edge 48a on the opposite side to the center part 41a of the opening-closing operation part 40a (that is, does not satisfy | fill a 1st condition). Do). The outer circumferential edge of the heating region 102a does not intersect the side edges 46a and 46b on both sides in the width direction of the open / close operating portion 40a (that is, the second condition is not satisfied).

On the other hand, the heating area 112a shown in FIG. 9B has a substantially rectangular shape protruding from the upper end part 42a of the opening-closing operation part 40a. Therefore, this heating area | region 112a contains the terminal edge 48a on the opposite side to the center part 41a of the opening-closing operation part 40a similarly to the heating area of this embodiment (1st condition). However, unlike the heating area of this embodiment, in the intersection P12a, P12b of the outer peripheral edge of the heating area 112a and the side edge edge 46a, 46b of the width direction of the opening-closing operation part 40a, the heating area 112a is carried out. The outer peripheral edge of is perpendicular to the longitudinal direction of the opening and closing operation part 40a (that is, does not satisfy the second condition).

As in the heating region 102a shown in FIG. 9A, the termination region 48a of the opening / closing operation portion 40a is provided unless the heating region includes the terminal edge 48a on the side opposite to the center portion 41a of the opening / closing operation portion 40a. It does not adhere to the flexible resin sheet 20a, but floats from the flexible resin sheet 20a. Therefore, there is a problem that the edge edge 48a is caught on the operator's skin, the texture of the medical soft container is lowered, the appearance is poor, and the appearance is poor, and the quality is reduced. In contrast, in the present invention, as shown in FIG. 7A, the heating region 52a includes the entirety of the end edge 47a on the side opposite to the center portion 41a of the opening and closing operation portion 40a (first condition). Therefore, since the edge 48a is in close contact with the flexible resin sheet 20a, the above problem can be solved.

Moreover, since the heating area 52a contains the whole terminal edge 47a of the opening-and-closing operation part 40a (1st condition), the area | region in which the upper end part 42a of the opening-and-closing operation part 40a is heat-sealed by the flexible resin sheet 20a. The overlapping region of the phosphorus and heating region 52a and the upper end portion 42a becomes large. Therefore, necessary adhesion strength with respect to the flexible resin sheet 20a of the opening-closing operation part 40a can be easily ensured.

On the other hand, like the heating area 112a shown in FIG. 9B, in intersection P12a, P12b, if the outer peripheral edge of a heating area is not inclined with respect to the longitudinal direction of the opening-and-closing operation part 40a, the following problem arises. That is, as shown in FIGS. 5 and 6, a finger is inserted into the insertion path 45a of the opening / closing operation unit 40a to open the opening 22, or the medical soft state in which the finger is inserted into the insertion path 45a. When a liquid substance is injected into the container 1, the external force which isolates the center part 41a from the soft resin sheet 20a acts on the center part 41a of the opening-closing operation part 40a. This external force acts in an oblique direction with respect to the longitudinal direction of the opening-closing operation part 40a in most cases when seen from the perpendicular direction with respect to the flexible resin sheet 20a. As shown in Fig. 9B, if the outer circumferential edge of the heating area 112a is perpendicular to the longitudinal direction of the opening and closing operation part 40a at the intersection points P12a and P12b, the external force in the oblique direction acts locally on the intersection points P12a and P12b. The stress is concentrated in the intersections P12a and P12b, and in the worst case, there arises a problem that the flexible resin sheet 20a is torn at the intersections P12a and P12b. On the other hand, in this invention, as shown to FIG. 7A, the outer peripheral edge of the heating area | region 52a inclines with respect to the longitudinal direction of the opening-and-closing operation part 40a in intersection P12a, P12b (2nd condition). Therefore, the said external force of the said oblique direction distribute | distributes to the area | region A1, A2 on the outer peripheral edge of the heating area | region 52a containing intersection P12a, P12b, and acts. Therefore, a large stress concentration like FIG. 9B does not occur, and the situation that the flexible resin sheet 20a is torn can be prevented.

In the above, the effect of the heating area | region 52a on the upper end part 42a of the opening-closing operation part 40a shown in FIG. 7A was demonstrated to the example, but the same also applies to other heating area | regions 52b, 53a, and 53b.

In this embodiment, all of the upper and lower ends 42a, 42b, 43a, and 43b of the opening and closing operation parts 40a and 40b satisfy the first condition and the second condition. 7A, 7B, 8A, and 8B), and is fixed to the flexible bag member 20 by a heat seal. However, the present invention is not limited to this. That is, in the present invention, at least one of the ends 42a, 42b, 43a, 43b fixed by the heat chamber may be fixed by the heat chamber accompanied by a heating region that satisfies the first condition and the second condition. Preferably, the upper end part 42a and / or the upper end part 42b are fixed by a heat chamber carrying a heating area that satisfies the first condition and the second condition. This is because the upper end portions 42a and 42b easily act on the weight of the liquid substance injected into the medical soft container 1, and the stress concentration described in FIG. 9B is likely to occur.

In the present embodiment, the substantially circular arcs 52a1, 52b1, 53a1, 53b1 constituting the heating regions 52a, 52b, 53a, 53b do not need to be circular arcs in a rigid sense with a constant curvature. What is necessary is just the curve which was convex toward the center part 41a, 41b side of the opening-closing operation part 40a, 40b, and the curvature may change. For example, part of an ellipse may be sufficient.

Moreover, the line segments 52a2, 52b2, 53a2, and 52b2 which comprise the heating area | region 52a, 52b, 53a, 53b do not need to be a straight line in a strict meaning, and may contain the curved or curved part.

The materials of the flexible resin sheets 20a and 20b and the opening / closing operation portions 40a and 40b constituting the flexible bag member 20 are not particularly limited. For example, conventionally known soft resins used for medical soft containers are available. Sheets can be used. Specifically, for example, a single layer sheet made of a vinyl chloride resin, polyethylene, ethylene-vinyl acetate copolymer, polyester, polybutadiene, polypropylene, polyamide, ethylene-methacrylate copolymer, or the single layer sheet. The laminated sheet which laminated | stacked two or more layers temporarily is mentioned. As a specific laminated constitution of a laminated sheet, nylon / polyethylene, nylon / polypropylene, polyethylene terephthalate / polyethylene, polyethylene terephthalate / polypropylene, polypropylene / polyethylene, nylon / polypropylene / polyethylene, etc. are mentioned, for example. . Or even a lamination sheet (e.g., biaxially stretched polypropylene (OPP) / non-stretched polypropylene (CPP), etc.) in which the same kind of resins having different grades (for example, film formation methods, mechanical properties or compositions) are laminated. do. The materials of the flexible resin sheets 20a and 20b and the opening and closing operation parts 40a and 40b may be the same or different. It is preferable that the surface of the heat-sealing side is comprised from the material (for example, polypropylene) which has easy heat-sealing property. The thickness of the flexible resin sheets 20a and 20b is not particularly limited, but is, for example, about 0.1 to 0.6 mm. The soft resin sheets 20a and 20b are preferable because they have a light transmissive (or translucent) state because the liquid substance in the accommodating portion 21 can be visually recognized from the outside. More preferably, the flexible resin sheets 20a and 20b are transparent.

The material of the discharge port 30 is not particularly limited, but a material that is harder than the material of the soft resin sheets 20a and 20b is preferable. Specifically, cyclic polyolefin, polycarbonate, polyethylene terephthalate, polypropylene, polyethylene naphthalate, etc. are mentioned, for example.

(Embodiment 2)

This Embodiment 2 is related with the shape of the heating area of the upper-lower edge part 42a, 42b, 43a, 43b of the opening-closing operation part 40a, 40b, and is different from Embodiment 1. FIG. The second embodiment will be described below mainly on the points different from the first embodiment.

FIG. 10A is an enlarged view showing the upper end portion 42a of the opening-closing operation portion 40a on the front side and the heating area 62a by the heat chamber in the second embodiment. FIG. 10B is a front view in the second embodiment. It is an enlarged view which shows the lower end part 43a of the opening-closing operation part 40a, and the heating area 63a by a heat chamber. The upper end part 42a and the lower end part 43a of the opening-closing operation part 40a are fixed to the flexible resin sheet 20a in the overlapping area | region with the heating area | regions 62a and 63a.

Although illustration is abbreviate | omitted, the heating area | region with respect to the upper end part 42b and the lower end part 43b of the opening-closing operation part 40b of the back surface side is surface symmetry with the heating area | regions 62a and 63a. Therefore, the description regarding the heating area | region 62a, 63a with respect to the upper end part 42a and the lower end part 43a of the opening / closing operation part 40a below is the upper end part 42b and the lower end part 43b of the opening-and-closing operation part 40b of the back surface side. The same applies to the heating zone for).

The external shape of the heating area | regions 62a and 63a of this embodiment has substantially trapezoid shape. The short sides 62a2 and 63a2 of two substantially parallel sides which comprise substantially trapezoid shape are arrange | positioned rather than the long sides 62a1 and 63a1 at the center part 41a side of the opening-and-closing operation part 40a.

In this embodiment, the heating area | region 62a, 63a contains the whole edge edge 47a, 48a on the opposite side to the center part 41a of the opening-closing operation part 40a (1st condition). Moreover, the intersection point P12a of the outer periphery of the heating area | region 62a, 63a (in this embodiment, substantially trapezoid quadrilateral 62a3, 62a4; 63a3, 63a4) and the side edge edge 46a, 46b of the both sides of the width direction of the opening-closing operation part 40a. , P12b; In P13a and P13b, the outer peripheral edges of the heating areas 62a and 63a (quadrilaterals 62a3, 62a4; 63a3, 63a4) are in the longitudinal direction (in the present embodiment, in the central axis 1a direction) of the opening / closing operation portions 40a and 40b.

Moreover, since the heating area 62a, 63a contains the whole terminal edge 47a, 48a of the opening-closing operation part 40a (1st condition), the upper end part 42a and the lower end part 43a of the opening-and-closing operation part 40a become soft resin. The area | region heat-sealed by the sheet | seat 20a becomes large. Therefore, necessary adhesion strength with respect to the flexible resin sheet 20a of the opening-closing operation part 40a can be easily ensured.

Moreover, in the intersection P12a, P12b, the outer peripheral edges (namely, quadrangle 62a3, 62a4; 63a3, 63a4) of the heating area 62a, 63a are inclined with respect to the longitudinal direction of the opening-closing operation part 40a, 40b (2nd condition). Therefore, even if the external force which isolates the center part 41a from the flexible resin sheet 20a acts on the center part 41a of the opening-and-closing operation part 40a, big stress concentration does not generate | occur | produce, and the flexible resin sheet 20a will tear. Can prevent the situation.
