Description

  The present invention relates to a medical bag that is used in the medical field and contains a liquid such as a nutrient solution, a chemical solution, or an infusion solution.

  In the medical field, liquids such as medicinal solutions and infusions are used. For the handling of such liquids, for example, a medical bag as described in JP 2011-78737 A (Patent Document 1) is used. Yes. That is, for example, in an enteral nutrition method in which a nutrient solution or a drug solution is administered to the stomach or the like through a tube inserted from the patient's nasal cavity, a medical bag contains a nutrient solution or drug solution that contains a predetermined amount of the nutrient solution or drug solution It is used as a bag. In addition, in a parenteral nutrition method in which a nutrient solution or a drug solution is administered to a vein through an infusion circuit inserted into a patient's vein, a medical bag is used as an infusion bag for storing a predetermined amount of the nutrient solution or the drug solution. Yes.

  By the way, other operations may be required for administration of such nutrient solutions, drug solutions, and infusion solutions. For example, after administration of a nutrient solution or a drug solution using a medical bag, water may be administered to a patient or a used tube may be washed using a syringe. Alternatively, other chemicals may be administered using a syringe before, after, or simultaneously with the administration of the medical solution using the medical bag. At that time, in addition to the medical bag and the chemical solution stored in the medical bag, the above-described syringe, water, chemical solution, and the like stored in the syringe may be additionally required.

  However, in general, these operations are performed on the patient's bedside. However, conventionally, there is often a case where there is not enough space on the patient's bedside to temporarily place the additional items. . For this reason, nurses sometimes bring these syringes and chemicals to the patient's bedside. In such cases, the nurse needs to know the syringes and chemicals necessary for each patient, It was necessary to go back and forth between the bedside and the nurse station.

  In view of such a problem, the present inventor additionally provides a pocket in the central portion of one of the two sheets constituting the medical bag, and additionally requires a syringe or the like in the pocket. It was also considered to accommodate what would be. However, when a pocket is provided by fixing the peripheral portion of another sheet by welding or adhesion to the central portion of the thin and soft resin sheet, the other sheet is fixed to a portion that is simply a single resin sheet. Therefore, there are concerns about insufficient strength and damage, which is not preferable from the viewpoint of quality assurance. Further, when the peripheral portion of another sheet is fixed to the central portion of the resin sheet, only the central portion where the other sheets are superimposed on the resin sheet is not easily deformed locally, and the deformation of the medical bag becomes distorted. There was also a risk that the handling of medical bags would be hindered.

  In addition, a tension tab 32 is fixed to the outer surface of the upper portion of the first sheet 14. The material of the tension tab 32 is not limited at all. In this embodiment, the tension tab 32 is a substantially rectangular sheet piece, and is formed in a size that can be picked up by a finger 44 (see FIG. 4). In particular, in this embodiment, only the upper side portion of the tension tab 32 is fixed to the upper portion of the first sheet 14, and the lower side portion of the tension tab 32 is a free end. Accordingly, the lower side portion of the tension tab 32 is raised from the first sheet 14, picked with the fingers 44, and pulled outward (toward the front side of the paper in FIG. 1), thereby mainly extending the upper portion of the first sheet 14. Are pulled in the same direction, the first sheet 14 and the second sheet 16 are separated from each other, so that the opening 18 of the liquid material containing region 12 can be opened more greatly.

  Here, on the outer surface of the second sheet 16, a third sheet 34 separated from the first and second sheets 14 and 16 is superimposed and fixed. In the present embodiment, the third sheet 34 is a thin member formed of a soft synthetic resin, like the first and second sheets 14 and 16, and is colored or colorless and transparent. . The material of the third sheet 34 is not limited at all. In the present embodiment, the third sheet 34 has a substantially rectangular shape extending in the vertical direction, and the width direction dimension of the third sheet 34 is substantially equal to the width direction dimension of the second sheet 16. In addition, the vertical dimension of the third sheet 34 is substantially equal to or slightly smaller than the vertical dimension of the second sheet 16. The third sheet 34 may have the same shape as the first and second sheets 14 and 16, and the same member as the first and second sheets 14 and 16 may be used.

  An insertion slit 36 serving as an insertion hole 48 into which the finger 44 is inserted when the medical bag 10 described later is gripped is formed in the upper portion of the third sheet 34. The insertion slit 36 extends in the vertical direction with a predetermined dimension. In this embodiment, the pair of insertion slits 36 and 36 face each other with a predetermined separation distance in the width direction. Thereby, the fingers 44 can be inserted into the medical bag 10 from both lateral sides, that is, from the right side insertion slit 36 and the left side insertion slit 36 in FIG. 2. The insertion slit 36 extends downward from a portion located a predetermined distance below the upper end of the third sheet 34 and straddles the plastic fastener 20 provided between the first and second sheets 14 and 16. It is formed with. That is, the insertion slit 36 is formed on the outer side of the plastic fastener 20 (the front side in FIG. 2).

  In addition, an opening slit 38 as a slit extending in the width direction is formed in an intermediate portion in the vertical direction of the third sheet 34. The opening slit 38 is formed through the third sheet 34, and is provided below the insertion slit 36 with a predetermined width direction dimension.

  The third sheet 34 is fixed to the second sheet 16 by heat welding with the upper side portion, the lower side portion, and both sides of the width direction being overlapped. That is, the lower side portion and the width direction both side portions of the third sheet 34 are integrally welded to the lower side portion and the width direction both side portions of the first and second sheets 14 and 16, respectively. In particular, in the present embodiment, the lower side portion of the third sheet 34 is integrally welded over the substantially entire length in the width direction with respect to the lower side portions of the first and second sheets 14 and 16. The lateral sides of the third sheet 34 are integrally welded to the lateral sides of the first and second sheets 14 and 16 over substantially the entire length in the vertical direction. As a result, a closed region 40 that is blocked from the external space is formed between the overlapping surfaces of the third sheet 34 and the second sheet 16, and the closed region 40 is formed by the third sheet 34. It is opened to the external space through an opening slit 38 formed so as to penetrate through. As a result, a pocket-shaped holding portion 42 having an opening slit 38 as an upper opening is formed in the lower portion of the closed region 40. Note that the upper side portion of the third sheet 34 need not be fixed to the second sheet 16. That is, a vertically long pocket portion that opens upward is formed between the overlapping surfaces of the third sheet 34 and the second sheet 16, and the lower portion of the pocket portion serves as the holding portion 42. Good.

  By the way, although the manufacturing method of such a medical bag 10 is not limited at all, one specific example of the manufacturing method of the medical bag 10 is demonstrated below.

  First, the first sheet 14 and the second sheet 16 may be prepared in advance with a desired shape, but preferably a long resin sheet having a predetermined width is wound into a roll shape. In the state, the 1st sheet | seat 14, the 2nd sheet | seat 16, and the 3rd sheet | seat 34 are each prepared. Similarly, the ridges 20a and the grooves 20b constituting the plastic fastener 20 are prepared in a state where a long object is wound in a reel shape. The scale 30 attached to the first sheet 14 may be preliminarily printed in a rolled state, or may be printed after the first sheet 14 and the second sheet 16 are welded. it can.

  And with respect to the press welding area of the press welding apparatus for heat-welding a resin sheet, the resin sheet of the 1st sheet | seat 14, the resin sheet of the 2nd sheet | seat 16, and the resin sheet of the 3rd sheet | seat 34 Are pulled out from the respective rolls, and the three resin sheets are led to overlap each other. The insertion slits 36 and 36 and the opening slit 38 in the third sheet 34 are preferably formed before the third sheet 34 is introduced into the press welding area, but are not limited. It may be formed after press welding.

  Further, the first and second sheets 14 and 16 are each provided with one of the ridges 20a and the grooves 20b constituting the plastic fastener 20 in a fastener welding area as a preparation area up to the press welding area of both sheets. Is pulled out of the reel and overlaid. The ridges 20 a and the grooves 20 b are continuously welded in the length direction to the resin sheet of the first sheet 14 and the resin sheet of the second sheet 16. As is well known, such welding is performed by using the resin sheet of the first sheet 14 and the resin of the second sheet 16 in the sheet-like portions 21 and 21 that are integrally provided by projecting from the ridges 20a and the grooves 20b to both sides in the width direction. By continuously welding linearly in the length direction to the sheet, it is possible to avoid the thermal influence on the opening / closing function portions of the ridges 20a and the grooves 20b. In addition, the sheet-like part 21 which protrudes from the protrusion 20a and the groove 20b on both sides in the width direction and is integrally provided is preferably a sheet material having high rigidity. In this way, one of the ridges 20a and the grooves 20b constituting the plastic fastener 20 is fixed to the overlapping surface of the first and second sheets 14 and 16 in advance.

  And the resin sheet of the 1st sheet | seat 14, the resin sheet of the 2nd sheet | seat 16, and the resin sheet of the 3rd sheet | seat 34 led into the press-welding area are mutually piled up, and it is the target medical use. The welding mold is pressed against the welding portions 22 set on the left and right side portions and the lower side portion of the bag 10 for press welding. At the time of this press welding, the ridges 20a and the grooves 20b located at the welding portion 22 are thermally deformed and crushed and substantially disappear. Further, when the upper side portion of the third sheet 34 is welded to the second sheet 16, in order to avoid mutual welding of the first and second sheets 14, 16, for example, the welding prevention sheet is used as the first and second sheets. This can be realized by press welding in a state of being sandwiched between the second sheets 14 and 16.

  Thereafter, the laminated sheet-like welded body fed out from the press welding area is introduced into the cutting area, and is punched and cut in a planar shape of the target medical bag 10 by the press cutter. Thus, the upper opening 18 that can be opened and closed by the plastic fastener 20 between the overlapping surfaces of the first and second sheets 14 and 16 to which the left and right side portions and the lower portion are integrally fixed. Is formed. Further, between the overlapping surfaces of the second sheet 16 and the third sheet 34 to which the upper side portion and the lower side portion, and the four sides of the width direction both side portions are integrally fixed, are blocked from the external space. A closed region 40 is formed.

  Further, the tensile tab 32 is welded to the first sheet 14 before or after the cutting process. This welding can be realized by, for example, press welding in a state where a welding prevention sheet is sandwiched between the first and second sheets 14 and 16.

  Note that the tensile tab 32 may be welded by an individual manual welding operation after the cutting process is performed to obtain the planar shape of the target medical bag 10.

  The port member 24 is in a state in which the port member 24 is sandwiched between the first and second sheets 14 and 16 in the press welding process of the first and second sheets 14 and 16 and the third sheet 34. The port member 24 can be welded simultaneously with the press welding of the first and second sheets 14 and 16 by press welding using a welding mold having a recess corresponding to the port member 24. Or after welding the welding part 22 of the 1st and 2nd sheet | seats 14 and 16 in the state which remained without welding only the adhering part of the port member 24, the port member 24 is inserted and it welds by another process. Alternatively, it may be bonded and fixed.

  As mentioned above, although the manufacturing process of the medical bag 10 of this embodiment was illustrated, as mentioned above, it is not limitedly interpreted by the above-mentioned manufacturing process. For example, the plastic fastener 20 is fed into the press-welding area of the first sheet 14 and the second sheet 16 in a state where the ridges 20a and the concave grooves 20b are engaged (the plastic fastener 20 is closed). Simultaneously with press welding to the welded portion 22, it is possible to weld to one of the both sheets 14,16. In the present embodiment, the first and second sheets 14 and 16 and the third sheet 34 are fixed simultaneously. However, the first and second sheets 14 and 16 and the third sheet 34 are Each may be fixed in order.

  In the medical bag 10 of this embodiment having such a structure, as shown in FIG. 4, the medical bag 10 is held by inserting the finger 44 into only one of the front and back sides. That is, in FIG. 4, assuming a right-handed user, the left hand finger 44 is inserted between the second sheet 16 and the third sheet 34, and the second sheet 16 and the third sheet 34 are inserted. An insertion portion 46 into which a finger 44 is inserted is formed between the sheet 34 and the sheet 34. In FIG. 4, four fingers 44 excluding the thumb are inserted into the insertion portion 46, but the type and number of fingers inserted into the insertion portion 46 are not limited at all.

  In particular, in the present embodiment, the finger 44 is inserted from the right insertion slit 36 in FIG. 2, while the tip of the finger 44 projects from the left insertion slit 36 in FIG. That is, in the third sheet 34, an insertion portion 46 is configured in which the finger 44 is inserted between the facing of the pair of insertion slits 36, 36 and the second sheet 16, and the insertion portion 46 has a width. It penetrates in the direction. And the opening part of the width direction both sides in the insertion part 46 is made into the insertion holes 48 and 48 in which the finger | toe 44 is inserted substantially, The said insertion hole 48 is comprised including the insertion slit 36. FIG. That is, in the present embodiment, the insertion portion 46 and the insertion hole 48 into which the finger 44 is inserted are formed outside the plastic fastener 20.

  In the present embodiment, the finger 44 is inserted into the back side of the medical bag 10 to hold the medical bag 10 as described above, while the tension tab 32 is held by the opposite finger (that is, the right hand). By pulling and pulling, the first sheet 14 is pulled together with the tension tab 32, so that the second sheet 16 and the first sheet 14 are separated from each other, and the opening 18 is more reliably opened. It is designed to be held in a state. As a result, the liquid material can be stored in the liquid material storage region 12 through the opening 18 in the open state, and the liquid material is administered into the body through the port member 24 and the catheter connected to the port member 24. It has become so. In addition, when picking and pulling the tension tab 32, it is desirable that the meshing of the protrusions 20a and the grooves 20b of the plastic fastener 20 is released in advance, but is not limited thereto.

  In the present embodiment, a suspended portion 26 having a locking hole 28 formed at the center is formed at the upper ends of the first sheet 14 and the second sheet 16.
