Definitions

  • the present invention relates to a spout for discharging contents filled in a liquid container and to a liquid container with the spout.
  • Tube feeding is known as a treatment for those who cannot take meals by mouth.
  • Tube feeding is a treatment where nutrition is sent directly to the body through a tube.
  • a nutrient bag filled with a nutrient is used in tube feeding, and the nutrient supplied from the nutrient bag flows through a tube and is sent to the body.
  • a supply system for sending the contents of a bag to the body through a tube also is utilized in transfusion for administering drug solutions.
  • FIG. 25 is a schematic diagram showing one example of a nutrient supply system using a conventional nutrient bag and one example of a drug solution supply system using a conventional drug solution bag.
  • a bag main body 101 of a nutrient bag 100 is filled with a nutrient.
  • a tube 105 provided with a connecting portion 104 at its end is connected.
  • a spout 102 is sealed with a liquid stopper cap 103.
  • the spout 102 and the end of the tube 105 can be connected to each other by removing the liquid stopper cap 103.
  • a bag main body 111 of a drug solution bag 110 is filled with a drug solution.
  • the drug solution is taken from a drug solution bottle (not shown) through a tube (not shown) connected to a tube connector 112.
  • a needle 114 When administering the drug solution to the body, a needle 114 is inserted into a needle port 113. Consequently, the drug solution can be sent to the body through a tube connected to the needle 114.
  • the connecting portion 104 is designed such that it is to be fitted to the spout 102 of the nutrient bag 100. For this reason, the connecting portion 104 cannot be fitted to the needle port 113 of the drug solution bag 110, so that the connecting portion 104 will not be connected to the drug solution bag 110 by mistake under normal conditions.
  • the liquid stopper cap 103 is made of a soft material so that it easily can be attached to and removed from the spout 102. Therefore, the needle 114 can be inserted into the liquid stopper cap 103. In this case, the needle 114 penetrates the liquid stopper cap 103 and reaches inside the spout 102. When such accidental insertion occurs, the nutrient will be administered through the transfusion line for supplying the drug solution, which raises the possibility of medical accidents.
  • Patent document 1 proposes a connecting needle penetration prevention structure provided on a portion corresponding to the spout 102.
  • This connecting needle penetration prevention structure is a spiral member, an intermediate plate member, a mesh member or the like provided inside a tubular portion, and penetration of a connecting needle is prevented by means of these members.
  • Patent document 1 JP 2007-39121 A
  • the penetration prevention structure using a spiral member proposed in Patent document 1 is not a structure that stops penetration at the leading end of the tubular portion but is a structure where the entry of a connecting needle into the tubular portion to some extent is a prerequisite. Further, the penetration prevention structure using an intermediate plate member or a mesh member is likely to deform or be cracked when a connecting needle is pressed into it.
  • the spout of the present invention is a spout that can be attached to a liquid container and through which contents filled in the liquid container are discharged.
  • the spout includes: a tubular portion in which a through hole is formed and from a leading end of which the contents are discharged and a rib that extends from an inner circumferential surface of the tubular portion towards a central axis side of the through hole. A hole surrounded by an edge of the extended rib is formed in a part where the rib is formed.
  • the liquid container with a spout of the present invention includes the spout of the present invention.
  • the structure for preventing accidental insertion is achieved by extending the rib from the inner circumferential surface of the tubular portion and forming a hole surrounded by the edge of the extended rib.
  • an inclined surface that inclines in the leading end side of the tubular portion towards the central axis of the through hole preferably is formed on the rib on the leading end side of the tubular portion.
  • an inclined surface that inclines in the leading end side of the tubular portion towards the central axis of the through hole preferably is formed on the rib on the base end side of the tubular portion.
  • incline surfaces that incline in the leading end side of the tubular portion towards the central axis of the through hole preferably are formed on the rib on the leading end side and the base end side of the tubular portion, respectively.
  • the spout further includes a base that is attached to the liquid container, the tubular portion protrudes from the base, and the protruding dimension of the tubular portion from the base is 1 mm or more and 10 mm or less.
  • the spout further includes an air-permeable filter.
  • the liquid container is preferably a pouch-like bag or a bottle.
  • the liquid container with a spout of the present invention includes a liquid stopper cap for sealing the spout, and when the liquid stopper cap is attached to the spout, the minimum distance between the leading end of the liquid stopper cap and the rib is 5 mm or less. Further, the minimum distance is more preferably 1 mm or less.
  • This configuration allows the liquid stopper cap to come into contact with the rib before the tip of the connecting needle penetrates the liquid stopper cap. Thus, even if the connecting needle remains inserted, it is possible to prevent the contents of the bag from being discharged.
  • FIG. 1 is a schematic view of a nutrient bag 1 according to one embodiment of the present invention.
  • a bag main body 2 as a liquid container is a part in which a nutrient is filled.

  • the bag main body 2 is soft resin sheets formed into the form of a pouch.
  • the bag main body 2 can be formed by, for example, laying a resin sheet on top of another resin sheet and heat welding the edge for bonding.
  • An opening 10 through which the nutrient bag 1 is hung is formed at one end of the bag main body 2.

  • the spout 4 After injecting the nutrient into the bag main body 2, the spout 4 is reattached to the port 3 to put it back in the state of FIG. 4(b) .
  • the nutrient bag 1 is transported in this state. Since a tube is not attached to the spout 4 in this state, a long tube does not get in the way of the transportation, and the nutrient bag 1 can be transported easily.
  • the spout 4 is screwed into the port portion 3 and the spout 4 is sealed with the liquid stopper cap 5. As a result, leakage of the contents of the bag main body 2 is prevented. Therefore, the nutrient bag 1 also can be placed laterally when being transported.

From one point between the tip part 120b and the main body part 120a, the diameter of the tip part 120b becomes larger than the diameter of the hole 21. Therefore, the tip part 120b of the connecting needle 120 enters the hole 21 but the entry of the tip part 120b is limited.
  • the connecting needle 120 can only be inserted for a small distance, so that accidental insertion is likely to be noticed. In this case, the connecting needle 120 will be removed, so that accidental insertion is prevented.
  • the hole 21 is surrounded by the edge of the rib 20 that extends from the inner circumferential surface of the tubular portion 9. That is, since there is no other hole between the edge of the rib 20 and the inner circumferential surface of the tubular portion 9, the rib 20 is a structure advantageous in preventing breakage and deformation.
  • resin needles normally have a hole 121 with a large length.
  • the hole 121 protrudes outside the liquid stopper cap 5 as shown in FIG. 10 .

  • the hole 121 protrudes outside the liquid stopper cap 5 more as the rib 20 is positioned closer to the leading end of the liquid stopper cap 5. For this reason, it is desirable that the minimum distance d between the leading end of the liquid stopper cap 5 and the rib 20 is set to be small in FIG. 5 . In this case, if the leading end of the liquid stopper cap 5 is configured not to press the rib 20, attachment of the liquid stopper cap 5 becomes easy.

For this reason, when the tip of the connecting needle 120 once comes into contact with the rib 20, the connecting needle 120 is less likely to enter the hole 21.
  • the minimum distance d between the leading end of the liquid stopper cap 5 and the rib 20 is set to be small. This is also effective in the case where the tip of the connecting needle 120 does not enter the hole 21 but comes into contact with the rib 20 as in FIG. 12 .
  • the tip of the connecting needle 120 has penetrated the liquid stopper cap 5. However, until being penetrated, the liquid stopper cap 5 is pressed by the connecting needle 120 and deforms elastically.
