Description

CAP, NUTRITIONAL SUPPLEMENT CONTAINER USING SAME, AND NUTRITIONAL SUPPLEMENT SUPPLY SET}

TECHNICAL FIELD The present invention relates to a cap attached to an inlet portion through which a liquid substance filled in a container body portion of a nutrient container is discharged, a nutrient container attached to the container body portion, and a nutrient supply set.

Enteral nutrition therapy and intravenous nutrition therapy are known as a method of administering nutrition or drugs to a patient without being oral. In enteral nutrition therapy, a tube that passes from the patient's nasal cavity to the stomach or duodenum (generally called the `` suspendal tube '') or the gastrointestinal tract formed in the patient's abdomen (a procedure that forms the gastrointestinal tract is called a `` Percutaneous Endoscopic Gastrostomy ''). A liquid such as a nutrient, a fluid, or a medicament (generally called an enteral nutrient) is administered through a tube (commonly called a "PEG tube") inserted into the tube. In intravenous nutrition therapy, a liquid (generally referred to as a "sap") containing nutrients such as glucose or a drug component is administered through a fluid line (feeding circuit) inserted into a patient's vein. .

22, the schematic block diagram of an example of the enteral nutrition set used for conventional enteral nutrition therapy is shown. The nutrient is filled in the container main body 101 of the nutrient container 100. A thin film (not shown) is attached to the inlet portion 102 through which the nutrient in the container body 101 flows out, and the inside of the container body 101 is sealed. When administering a nutrient to the body, the plastic connecting needle 104 is punctured by a cap 105 attached to the inlet portion to penetrate the thin film. Thereby, the nutrient can be moved into the body through the tube connected to the connecting needle 104.

23, the schematic block diagram of an example of the infusion set used for the conventional vein nutrition therapy is shown. The bag body 111 of the bag 110 is filled with a liquid containing a nutrient component and a pharmaceutical component. When administering a liquid substance in the body, the connecting needle 114 is punctured by the connecting needle port 113. Thereby, a liquid substance can be moved in a body through the tube connected to the connection needle 114 (refer patent document 1).

In a preferable example of the cap of the present invention, the communication member includes a plurality of flow paths, and a plurality of holes are formed in the cross section on the side opposite to the thin film side of the communication member. For example, it is preferable that the communicating member includes a plate-shaped portion at an end portion on the opposite side to the thin film side, and the plate-shaped portion preferably has a hole forming a part of each flow path. The fact that a plurality of holes are formed in the cross section can also be said that one through hole is partitioned into a plurality of small holes, and the structure is such that it is difficult to insert a sharp connecting needle into the through hole. As described above, if the communication member has a structure in which the connecting needle with a sharp tip is hard to be inserted into the communicating member, only the liquid feeding circuit for intravenous nutrition therapy that moves the liquid into the body by poking the connecting needle with a sharp tip at the connection object Incorrectly, the problem of incorrect connection to the nutrient container used for enteral nutrition therapy is solved more reliably.

In a preferable example of the cap of the present invention, the communicating member is disposed on the thin film side rather than the plate-shaped portion, and includes a partition wall disposed to partition the space in the extending direction of each hole. In this case, since the communication member becomes light weight and it is easy to shape a communication member, for example, compared with the case where the external shape of a communication member is a substantially cylindrical shape, it is preferable.

In a preferable example of the cap of the present invention, the communication member projects outward in a part of the portion farther from the thin film side tip than the puncture portion. In this case, after the thin film is punched by the puncturing portion, the portion projecting in the outward direction is in contact with an unopened portion of the thin film, so that the communication member is effectively prevented from falling into the container body portion.

In a preferable example of the cap of the present invention, the bridge connects the communication member and the cap main body so as to span a flow path through which the liquid substance filled in the container main body can flow out of the nutrient container. In this case, since the bridge is arranged so as to traverse the lumen (flow path) in the communication member, a sharp connecting needle is hard to be inserted into the communication member, so that the misconnection can be prevented more reliably.

In a preferred example of the cap of the present invention, the portion including the bridge from the connection portion of the cap body portion and the bridge to the connection portion of the bridge and the communication member is bent and deformed, thereby allowing the communication member to be pushed toward the container body portion side. . In this case, since a thin film can be perforated with the cap main body part and the communication member connected, it is preferable because the communication member can be prevented from falling in a container main body part and floating in a liquid substance.

For example, the part including the bridge from the connection part of a cap main body part and a bridge to the connection part of a bridge and a communication member contains three thin parts, and each of the three thin parts is bent and deformed. If it is, the communication member can be easily pushed to the container main body side. When the number of the thin parts is three, when the communication member is pushed toward the container main body side, the bridge is broken due to the small number of thin parts, or the bending method is complicated because the number of the thin parts is too large, which is preferable.

In a preferable example of the cap of the present invention, a protective cover is provided that covers the communication member and includes an engaging portion that can engage the connection holding structure of the cap. In this case, external force is prevented from being applied to the communication member when it is not desired. Therefore, when it is not desired, an external force is applied to the communication member, so that the thin film can be prevented from being penetrated by the communication member pushed toward the container main body side and pushed toward the container main body side.

FIG. 3A is an enlarged perspective view showing an example of the cap of the present embodiment constituting the nutrient container shown in FIG. 1, FIG. 3B is a partially enlarged view of the cap shown in FIG. 3A, and FIG. 3C is FIG. 3A is a bottom view of the cap shown in FIG. 3A, FIG. 3E is a side view of the cap shown in FIG. 3A, FIG. 3F is another side view of the cap shown in FIG. 3A, and FIG. 3G is sectional drawing of the cap shown in FIG. 3A, FIG. 3H is another sectional drawing of the cap shown in FIG. 3A. 3A has shown the figure larger than FIGS. 3C-3H for convenience of description.

As shown in FIG. 1 and FIG. 2, the nutrient container 10 is a medical nutrient container used for enteral nutrition therapy, and is filled in the bottle body 11, which is a container body part, and the bottle body 11. It includes a liquid containing a nutrient (not shown) and a cap 13 attached to the inlet 12 (see FIG. 2) of the bottle body 11. At the bottom of the bottle main body 11, a suspender (not shown) for suspending the bottle main body 11 is provided.

The bottle main body 11 is formed of a hard material, for example. Therefore, unless the external force is especially applied, the external shape is maintained. The bottle main body 11 is obtained by blow molding using a resin material, for example. As a resin material, polyethylene terephthalate (PET), polypropylene (PP), polyvinyl chloride (PVC), nylon, etc. are mentioned, for example.

As shown in FIG. 2, the inlet part 12 is formed in the outer peripheral surface with the external thread 12a for screwing together with the female screw 23 (refer FIG. 3H etc.) of the cap 13. As shown in FIG. The thin film 16 is attached to the inlet part 12 so as to close the opening of the inlet part 12, and the bottle main body 11 is sealed by the thin film 16. Therefore, even if the bottle main body 11 with the thin film 16 is directed so that the inlet portion 12 faces downward, the liquid substance in the bottle main body 11 does not leak from the bottle main body 11.

As a material of the thin film 16, aluminum foil, the laminated film which consists of paper and aluminum foil, the resin film containing resin similar to resin contained in the bottle main body 11, etc. are mentioned, for example. The resin film may be either a single layer film or a laminated film composed of a plurality of layers. Among them, from the viewpoint of securing high adhesion to the bottle body 11 of the thin film 16 by thermal welding, the same resin as the resin contained in the bottle body 11 is placed on the surface in contact with the bottle body 11. The resin film to contain is preferable.

The thin film 16 is bonded to the opening end face 12b of the inlet part 12, and the peripheral edge part 16a is stuck to the outer peripheral surface of the opening end face 12b vicinity of the inlet part 12. However, the thin film 16 may be bonded only to the opening end surface 12b of the inlet part 12. The bonding method of the thin film 16 to the inlet 12 is appropriately selected depending on the material of the thin film 16 and the material of the inlet 12.

As shown in FIG. 2, the cap 13 includes a cap body portion 22 and a communication member 19 connected to the cap body portion 22 via a bridge 19a (see FIG. 3B, etc.). . The cap main body 22, the bridge 19a, and the communication member 19 can be integrally molded by the injection molding method or the like. When the bridge 19a exerts a force pushing against the communicating member 19 toward the thin film 16 side by pressurization, any one of the bridges is separated, and the thickness, width, and the like thereof are appropriately determined depending on the material.

As shown to FIG. 3A-3G, the cap main-body part 22 contains the base 20 and the connection part 21. As shown in FIG. The base 20 has a ceiling surface portion 17 facing the opening of the inlet portion 12 and a side wall portion surrounding the outer circumferential surface of the inlet portion 12 when the cap 13 is attached to the inlet portion 12 ( 18). On the inner circumferential surface of the side wall portion 18, a female screw 23 (see FIG. 3H, etc.), which is screwed to the male screw 12a (see FIG. 2) formed on the outer circumferential surface of the inlet portion 12, is formed.

As shown in FIG. 3A, the connecting portion 21 includes a tubular portion 21a protruding from the outer main surface of the ceiling surface portion 17, a pedestal portion 21b formed around the tubular portion 21a, and a pedestal portion. It includes a pair of claw portions 21c protruding outward from the outer circumferential surface of 21b and provided around the tubular portion 21a. The outer peripheral surface of the front end side of the tubular portion 21a includes a tapered surface 211 having a larger diameter as it goes from the front end of the tubular portion 21a toward the base side. The pair of claw portions 21c function as a connection holding structure which enables the connection state with the connector 25 of the liquid feeding circuit 27 (refer to FIG. 5 etc.) mentioned later to be hold | maintained. As shown in FIG. 3B, the communication member 19 is connected to the tubular portion 21a of the cap body portion via the bridge 19a, and a part of the communication member 19 is inserted into the lumen. Therefore, the other part of the communication member 19 protrudes upward of the tubular part 21a. That is, the cap 13 includes a cap main body portion including the ceiling surface portion 17, the side wall portion 18, and the tubular portion 21a, and the communication member 19 having a portion thereof inserted into the tubular portion 21a. Include.

4: A is a perspective view explaining the bridge 19a and the communication member 19 which comprise a cap, and FIG. 4B is sectional drawing A-A 'of the communication member 19 shown to FIG. 4A. The communication member 19 includes the plate-shaped part 19e which is circular in planar shape at the edge part on the opposite side to a thin film side (opening side of the base part 20 of a cap), The plate-shaped part 19e has several A through hole 19d is formed.

In addition, the communication member 19 has a plurality of partition walls 19c that divide a plurality of spaces on the thin film side on the thin film side from the plate-shaped portion 19e. The partition 19c is arrange | positioned so that the space in the extension direction of each hole 19d may be mutually divided. Therefore, in order to connect the connector 25 of the liquid feeding circuit 27 (refer FIG. 5 etc.) to the cap 13, the communication member 19 is pushed to the bottle main body 11 side with the connector 25, and a puncturing part is carried out. When the thin film 16 is pierced by the 19b, the plurality of partitions 19c are formed, and the plurality of spaces 19g opened with respect to the internal space of the cap body portion 22 (base 20), and The plurality of through holes 19d function as a plurality of flow paths through which the liquid substance filled in the bottle body 11 can flow out of the nutrient container (in the direction of the arrow X). The communicating member 19 shown in FIG. 4A and FIG. 4B has four partitions, and therefore has four flow paths. Since the four partition walls are arranged at equal angles along the circumferential direction and are integrated with each other, as shown in FIG. 4B, the cross-sectional shape of the partition body composed of the plurality of partition walls 19c is approximately cross.

The communicating member 19 has the puncturing portion 19b on the thin film 16 side of both axial ends thereof. The puncture portion 19b is sharp enough so that its tip can penetrate the thin film 16. In the example shown in FIG. 4A, the plurality of partition walls 19c each have an inclined surface 19m inclined toward the tip of the thin film side of the communicating member 19, and each inclined surface 19m is a communicating member 19. A concave portion 19b that focuses on the tip 19f of the thin film side of the X-rays and penetrates the thin film 16 is formed.

As shown in FIG. 4A, the communicating member 19 protrudes outward from the puncturing portion 19b (radial direction) at any position away from the thin film side tip 19f than the puncturing portion 19b. It is preferable to have the portion 19h, in other words, the portion 19h protruding in the direction orthogonal to the longitudinal direction of the communication member 19 than the puncturing portion 19b. For example, each partition 19c protrudes outward from the puncturing portion 19b at any one of the partitions 19c away from the thin film side tip 19f than the portion constituting the puncturing portion 19b. It is preferable to have a wider portion 19h. After the thin film 16 is drilled by the puncturing portion 19b, the portion 19h is in contact with the unopened portion of the thin film 16, thereby preventing the communication member 19 from falling into the bottle body 11. do. In the example shown in FIG. 4A, the surface 19j facing the thin film of the portion 19h is in contact with an unopened portion of the thin film 16 to prevent the communication member 19 from falling into the bottle body 11. do.

The bridge 19a is provided so that it may protrude from the partition 19c to the outer side (for example, the direction orthogonal to the longitudinal direction of the communication member 19). About the number, shape, etc. of the bridge 19a, the communication member 19 is stably supported by the cap main-body part 22, and when pushing the communication member 19 to the thin film 16 side, the bridge 19a is carried out. As long as it can be easily broken, there is no restriction | limiting in particular, For example, the bridge 19a is arrange | positioned radially about the central axis of the communication member 19, and the surface which faces the inner peripheral surface of the tubular part 21a is You may be provided so that it may extend in an outward direction (radial direction) from the partition 19c at intervals of one of the some partition 19c arrange | positioned along the circumferential direction. For example, in the communication member 19 shown in FIG. 4A and FIG. 4B, since the number of the partitions 19c is four, the bridge 19a is provided only in the two partitions 19c which are 180 degrees apart.

As shown in FIG. 3A, FIG. 3C, and FIG. 3D, in the ceiling surface part 17 of the cap 13, the two ventilation holes 29 which penetrate in the thickness direction are formed, and the ventilation hole 29 is The ventilation filter 28 (refer FIG. 3D etc.) is attached to the inner main surface 17a of the ceiling surface part 17 so that it may coat | cover. The ventilation filter 28 is surrounded by an annular wall 28a provided on the inner main surface 17a of the ceiling surface portion 17. The vent filter 28 is a hydrophobic vent filter and allows gas to pass but not liquid. As the liquid substance filled in the bottle main body 11 flows out from the inlet part 12, the pressure in the bottle main body 11 becomes low. When the bottle main body 11 is formed with the soft material, the bottle main body 11 deform | transforms with the outflow of liquid water, and outflow of a liquid water continues. However, deformation of the bottle body 11 formed of a hard material is difficult. In this embodiment, air flows in into the bottle main body 11 through the ventilation filter 28 with the outflow of a liquid substance. Thereby, even if the needle body etc. are stuck in the bottle main body 11 in the middle of supplying the nutrient in the body, even if a hole for aeration is formed in the bottle main body 11, the outflow of the liquid substance from the bottle main body 11 is carried out. This can be done continuously.

As the ventilation filter 28, if it is a well-known minority filter used for connection needles, such as a needle, for example, there will be no restriction | limiting in particular about the material.

3D, 3G, 3H, 5-7, etc., the cap 13 has the annular sealing material 171 arrange | positioned on the inner main surface 17a of the ceiling surface part 17. As shown in FIG. It is preferable to include more. The seal member 171 is sandwiched between the inner main surface 17a of the ceiling surface portion 17 and the opening end face 12b (see FIG. 2) of the inlet portion 12 of the bottle body 11, so that the cap 13 and the inlet portion. The airtightness of the part 12 can be improved. Therefore, the liquid is prevented from leaking out of the gap between the cap 13 and the inlet 12 while effectively supplying the liquid to the patient. In addition, hatching is put in the sealing material 171 in FIG. 3D for convenience of illustration.

Examples of the material of the sealing material 171 include isoprene rubber, butylene rubber, thermoplastic elastomer, and the like.

In FIG. 5, a liquid feeding circuit 27 including a connector 25 and a flexible tube 26 connected to the connector 25 is connected to the connecting portion 21 and the communication member 19 of the cap 13. The shape immediately before it is shown is shown, and the connection part 21 and the communication member 19 are shown to FIG. 7A and FIG. 7B while the liquid feeding circuit 27 is connected to the connection part 21 and the communication member 19 in FIG. The liquid feeding circuit 27 is in the middle of being connected to each other, and the thin film 16 is bored.

As shown in FIGS. 5-7B, the connecting portion 21 and the communication member 19 are connected to the liquid feeding circuit 27 including the connector 25 described later using FIGS. 8A to 8E. It is. Therefore, the nutrient container 10 which is used for intravenous nutrition therapy by the liquid feeding circuit for intravenous nutrition therapy which moves a liquid substance in a body only by sticking a sharp connection needle with a sharp tip to a connection object (FIG. 1) Problem of incorrect connection is solved. Further, as shown in Figs. 4A to 4G, in the cross section on the side opposite to the puncturing portion 19b side of the communicating member 19, a plurality of through holes 19d are formed, and the tip of the connecting needle is sharp. Since it is hard to be inserted in this through hole, the said misconnection can be prevented more reliably.

5 to 7B, after the tubular portion 21a is pushed into the connector 25 and the connector 25 is rotated about its axis, the claw portion of the cap 13 will be described later. Since 21c is engaged with the engaging portion of the connector 25, the connector 25 is fixed to the connecting portion 21, so that the detachment of the connector 25 is surely prevented. In the state where the engaging portion of the claw portion 21c and the connector 25 are engaged, as shown in FIG. 7B, the outer circumferential surface 212 of the tubular portion 21a is the inner surface of the connector 25 (large diameter portion ( 33a)), the connector 25 and the cap 13 are connected without causing liquid leakage.

Although it is permissible to push in the thin film 16 side of 49, the bridge may contain one or more thin parts. When a force pushing against the communicating member 49 to the thin film side by pressing, bending and deforming, the connection of the communicating member 49 to the thin film side and the perforation of the thin film by the communicating member 49 are allowed to be connected. Although there is no restriction | limiting in particular about the shape of the site | parts 51 and 52, the number of thin parts, etc., The number of thin parts in the part Z has a small number of thin parts, a bridge is broken, or the number of thin parts is bent by too many. Three are preferable from a viewpoint of suppressing complexity of a law.

In addition, in the present embodiment, the bridge 49a is bent and deformed when a force pushing against the communicating member 49 toward the thin film side by pressing, and the thin film can be penetrated while the cap body portion and the communicating member are connected. Therefore, the communication member can be reliably prevented from dropping in the container main body portion and floating of the communication member in the liquid body. However, in the present embodiment, the communication member may be broken.

Moreover, the cap of this embodiment and the container for nutrients may be provided with the protective cover demonstrated in Embodiment 2. As shown in FIG.

In addition, although the liquid supply circuit 27 shown in FIG. 5 shows only a part of the connector 25 and the flexible tube 26 for convenience of illustration, it is connected to the cap and the nutrient container of Embodiments 1-4, Alternatively, the liquid feeding circuit constituting the nutrient supply set together with the nutrient container includes a flow regulator, a dropping tube, and a patient for pressing the flexible tube 26 to adjust the flow rate of the liquid flowing through the flexible tube 26. The component which the liquid feeding circuit used for conventionally known enteral nutrition therapy, such as a connector which can be connected to a fixed nasal tube, etc., the cover of the said connector, may be further included.

In the present invention, a nutrient supply set including a cap of a nutrient container suitable for enteral nutrition therapy, a nutrient container using the same, and the nutrient container can be provided.
