Description

  The present invention relates to a medical bag widely used for medical purposes such as an infusion bag and a blood bag.

  A medical bag is generally formed in a rectangular shape or the like, and is used in such a manner that a hanging hole provided in the upper center of the bag body is inserted into a holding member and a drug is taken out from a drug discharge port provided in the lower part. It is widely used in medical practice as an infusion bag, blood bag, etc. (see, for example, Patent Documents 1 and 2). In particular, a multi-chamber bag having a plurality of storage chambers partitioned by an easy opening partition portion (weak seal portion) has also been proposed (for example, Patent Document 3).

Further, the multi-chamber bag is suitable for separately storing a stock solution and a diluted solution. For example, “Otsuka CEZ Injection MC (Otsuka Pharmaceutical)” or “Pansporin” widely used in the medical field as an antibiotic dissolution kit. Intravenous bags (Takeda Pharmaceutical Co., Ltd.) ”. Such medical bags such as a multi-chamber bag are widely applied to drugs other than those described above.

  By the way, in the case of an antitumor agent or the like, conventionally, when administered to a human body, for example, a stock solution is sucked up with a syringe and injected into a diluent to be diluted to a predetermined concentration. If such a medicine is stored in a medical bag, the medicine can be handled in an aseptic state, and the safety is improved because the medicine is not directly touched.

  In that case, for example, in addition to the two storage chambers for separately storing the stock solution and the diluent, a medical device provided with a space partitioned by an easy-open partition between the drug discharge port provided in the lower portion and the stock solution storage chamber If the bag for use is used, it is possible to prevent troubles such that only the stock solution is mistakenly administered or the stock solution is inadvertently discharged from the drug discharge port before administration.

  In order to take out the medicine from the multi-chamber bag provided with such a space, first, the upper diluted solution storage chamber is strongly pressed to break the easy-open partition, and the stock solution and the diluted solution are mixed. Next, the easy-open partition part is broken by applying pressure to the easy-open partition part that divides the empty space so as to wind the bag body from the upper part to the lower part of the bag body through the liquid mixture. Introduce the mixture to the place. Next, the drug (mixed solution) can be discharged (administered) from the drug discharge port.

  However, when the above-described void is formed in a relatively large volume, only a part of the easy-open partition is broken when pressure is applied to the easy-open partition that partitions the void. In this state, the void is filled with the drug. In other words, the easy-open partitioning part that partitions the void is not fully opened, and in particular, there may remain unbroken parts at both ends. Then, after administration, the drug remains on the upper portion of the easy-open partition part that was not broken.

  In the case of an anti-tumor agent or the like in which the required dose is calculated in advance based on the patient's body surface area and filled in the bag body, the drug dose will remain if the drug remains in the bag body Will be lacking.

  The present invention has been made in view of such circumstances, and provides a medical bag configured so that a drug is not leaked inadvertently before administration and the drug does not remain in the bag body after administration. With the goal.

  By the way, as described above, all of the medical bags such as the conventional examples described above have a rectangular outer shape, and the appearance is relatively similar, so that the application to various drugs is further expanded in the future. In such a case, there is a concern that troubles such as erroneous selection of a medicine may occur in the identification only by displaying a label or the like. In particular, such a trouble should not occur in a medical bag in which a drug such as an antitumor agent requiring attention in handling is stored.

  In addition, when the amount of medicine to be accommodated increases and the size of the medical bag increases, the weight may not be stably supported only by the suspension hole provided at the upper center of the bag body. Auxiliary small holes were provided on both sides (both shoulders) of the hole to support at three points. However, in such a method, three suspension members are required and the suspension state lacks stability.

  Accordingly, the present invention provides a medical bag that can be clearly distinguished from others in appearance at a glance even when a specific medicine is stored, and can be stably suspended even when the size is increased. Also aimed at.

(1) The medical bag of the present invention has an easy-open partition part 81 inside a bag body 6 formed by heat-welding the peripheral parts of sheet materials 1 and 2 made of a heat-weldable flexible material. A plurality of divided drug storage chambers 31, 32 are arranged in the vertical direction, and are separated by the lower drug storage chamber 32 and the easy-open partition 82 and disposed in the lower portion of the bag body 6. In a medical bag in which a void 9 is provided adjacent to the outlet 5,
The volume of the empty space 9 is set to be smaller than the volume of the medicine accommodated in the medicine accommodating chambers 31 and 32, and after the easy opening partition portion 81 is broken, the bag body 6 is directed from the top to the bottom. By applying pressure to the easy-open partition 82 that wraps up and divides the drug storage chamber 32 and the space 9 below, the easy-open partition 82 is broken in the fully open state. It is characterized by that.

  According to such a configuration, the volume of the empty space 9 is set to be smaller than the volume of the medicine accommodated in the medicine accommodating chambers 31 and 32. Therefore, the bag body 6 is wound from the upper part toward the lower part. By applying pressure to the easy opening partition 82 that partitions the lower medicine storage chamber 32 and the space 9, a part of the easy opening partition 82 is broken and the space 9 is filled with the medicine. However, since the medicine surface exists above the easy-open partition part 82, if the further entrainment continues, a large pressure can be applied to the easy-open partition part 82, so that the easy-open partition part 82 is fully opened. It can be broken into a state. Therefore, it is possible to prevent the drug from being left in the bag body after the drug is administered with the bag body 6 suspended. Therefore, there will be no shortage of drug dose. In addition, although the chemical | medical agent as used in the field of this invention refers to a stock solution and / or a dilution liquid, for example, it shall contain medicines (for example, IFN solid agent etc.), such as powder and a solid agent.

(2) 1 to any one of the surfaces of the sheet materials 1 and 2 in the lower drug storage chamber 32 in which the drug is stored or the upper and lower drug storage chambers 31 and 32 in which the drug is stored and in communication. When a pressing force is applied to the vicinity of the center corresponding to an area of 25%, the easy opening partition portion 82 that partitions the lower medicine storage chamber 32 and the space 9 is not broken. You may comprise so that the inner walls of the said sheet materials 1 and 2 may contact.

  In this way, before the drug is administered, for example, a pressing force is inadvertently applied to an area of 1 to 25% of one surface of the sheet materials 1 and 2 in the drug storage chambers 31 and 32. Even in such a case, since the easy-open partition 82 that partitions the lower drug storage chamber 32 and the empty space 9 is not broken, it is possible to eliminate the trouble that the drug leaks before administration. Can do.

(3) The volume of the empty space 9 may be set to 40% or less of the volume of the medicine stored in the upper and lower medicine storage chambers 31 and 32. Thus, if the volume of the empty space 9 is set to 40% or less of the volume of the medicine, when the bag body 6 is rolled up and pressure is applied to the easy opening partition portion 82 that partitions the empty space 9, the easy opening partition portion Since a large pressure can be applied to 82, the easy-open partition 82 can be reliably broken in the fully opened state.

(4) The volume of the empty space 9 may be set to 30% or less of the volume of the medicine stored in the upper and lower medicine storage chambers 31 and 32. In this way, since a larger pressure can be applied to the easy-open partition part 82, the easy-open partition part 82 can be more reliably broken in the fully opened state.

(5) The volume of the empty space 9 may be set to 20% or less of the volume of the medicine stored in the upper and lower medicine storage chambers 31 and 32. In this way, an even greater pressure can be applied to the easy-open partition 82, so that the easy-open partition 82 can be more reliably broken to the fully open state.

(6) In order to reduce the volume of the void 9 on both sides of the void 9, the throttle walls 10, 10 are thermally welded so as to be tapered toward the medicine discharge port 5. It may be formed. In this way, the diaphragm walls 10 and 10 can be easily formed by heat welding without requiring any separate member in the manufacturing process, and the outer shape of the bag body 6 is left as it is. Space can be effectively reduced.

(7) The upper half portion of the bag body 6 may be formed in a substantially triangular shape having oblique sides 71, 71 on the left and right. If it does in this way, when applying pressure to easy opening partition part 82 which divides empty space 9, it will become easy to wind bag main part 6 from the upper part, and workability at the time of breaking easy opening partition part 82 will improve. . Further, the shape distinguishability becomes remarkable, and even when a specific medicine (for example, an antitumor agent) is accommodated, it can be clearly distinguished from others in appearance. Further, since the peripheral portions of the sheet materials 1 and 2 are heat-welded at the hypotenuses 71 and 71, if the suspension portion 4 is provided on the upper portion of the bag body 6, a suspension load acting on the suspension portion 4 is generated. Since it is evenly distributed to the left and right hypotenuses 71 and 72 whose rigidity is improved by heat welding, a suspension state that is stable in strength can be obtained. It should be noted that the hypotenuses 71, 71 on the left and right sides of the upper half of the bag body 6 may have different lengths, and may be curved or wavy.

(8) Even if the unwelded portions 11 and 12 for filling the medicine storage chambers 31 and 32 with the medicine are provided in a part of one of the oblique sides 71 and 72 of the medicine storage chambers 31 and 32, Good. If it does in this way, in a medicine filling process, a plurality of medicines (for example, dilution liquid and stock solution) can be filled up simultaneously. Moreover, after filling, both the unwelded parts 11 and 12 can be heat-welded simultaneously and closed.

(9) A diluent may be stored in the upper drug storage chamber 31, while an antitumor agent may be stored in the lower drug storage chamber 32. In this way, the antitumor agent can be rapidly diluted in a sterile state at the time of administration. In addition, safety is improved without touching human hands.

  In the medical bag of the present invention, since the volume of the void is set smaller than the volume of the drug accommodated in the drug accommodating chamber, the easy opening that partitions the lower drug accommodating chamber from the void is provided. Since the partition part can be broken to the fully open state, it is possible to prevent the drug from being left in the bag body after the drug is administered with the bag body suspended, so that the dose of the drug is insufficient. Nothing will happen.

  Hereinafter, the medical bag according to the best mode of the present invention will be described in detail with reference to the drawings. FIG. 1 is a front view of a medical bag, and FIG. 2 is a sectional view thereof. As shown in these drawings, this medical bag is composed of two sheet materials 1 and 2 made of a flexible resin material that can be heat-welded, and its peripheral portion (shown by hatching in FIG. 2) is heated. A bag body 6 is formed by welding, and a suspended portion 4 is formed at the upper portion thereof, while a medicine discharge port 5 is formed at the lower portion, and the bag body 6 is partitioned by an easy opening partition portion 81. In addition, two drug storage chambers 31 and 32, a lower drug storage chamber 32, and a space 9 adjacent to the drug discharge port 5 by being partitioned by the easy-open partition 82 are formed.

  The above-described void 9 is formed in a tapered shape toward the medicine discharge port 5 by the throttle walls 10 and 10 formed inside the right and left isosceles portions 72 and 72. And the external shape of the upper half part of the bag main body 6 is formed in the substantially isosceles triangle shape which has the isosceles part (slanted side of this invention) 71,71 to the left and right centering on the hanging part 4. FIG. Further, the outer shape of the lower half portion of the bag body 6 is such that left and right isosceles portions 72 and 72 are tapered toward the medicine discharge port 5. Further, unwelded portions 11 and 12 for filling a medicine are formed on one isosceles portion 71 and 72, respectively.

  When one of the sheet materials 1 and 2 in the drug storage chambers 31 and 32 storing the drug is pressed near the center, either the sheet material 1 or 2 in the drug storage chambers 31 and 32 is pressed. When the pressing force is applied to an area of 1 to 25% of the surface, the easy opening partition portions 81 and 82 partitioning the medicine storage chambers 31 and 32 are not broken, and the sheet materials 1 and 2 are broken. The inner walls are configured to contact each other.

  Further, after the easy opening partition portion 81 is broken, the bag body 6 is wound from the upper portion toward the lower portion, and pressure is applied to the easy opening partition portion 82 that partitions the drug storage chamber 32 and the space 9 below. By doing so, the easy-open partitioning part 82 is configured to be able to be broken in the fully opened state. For that purpose, it is preferable to set the volume of the medicine stored in the medicine storage chambers 31 and 32 to be larger than the volume of the space 9. More preferably, the volume of the empty space 9 may be set to 40% to 20% or less of the total volume of medicines stored in the medicine storage chambers 31 and 32.

Such a medical bag can be manufactured in the following procedures, for example.
First, two sheet materials 1 and 2 that have been molded are overlapped, and the peripheral portion (the right and left isosceles portions 71 and 72) is removed except for the portion where the medicine discharge port 5 is provided and the unwelded portions 11 and 12. ) Heat weld each other. At this time, the partition wall 4b immediately below the hanging part 4 and the throttle walls 10, 10 formed inside the left and right isosceles parts 72, 72 of the lower half of the bag body 6 are also thermally welded simultaneously. Subsequently, the easy opening partition parts 81 and 82 which become weak seal parts are formed by heat welding at a temperature lower than this.

  Next, the mouth member to be the medicine discharge port 5 is inserted between the sheet materials 1 and 2 at the lower part of the bag body 6, the periphery thereof is welded 13 and sealed, and the central part of the hanging part 4 is punched out and suspended. Hole 4a is formed. Then, after filling the medicine containing chambers 31 and 32 from the unwelded portions 11 and 12 provided in the one isosceles portion 71 and 72 to the medicine storage chambers 31 and 32 respectively, the unwelded portions 11 and 12 are welded. Once sealed, the production of the medical bag is complete. The present invention does not specify a manufacturing method, and may be manufactured by other methods.

  The medical bag as described above contains, for example, a diluent in the upper drug storage chamber 31 and a drug (toxic), for example, an anti-tumor, which requires careful handling in the lower drug storage chamber 32. Stock solutions such as agents can be stored. In addition, in the drug storage chamber 32, instead of the stock solution, a powder (eg, IFN solid agent) such as a powder or a solid agent that is dissolved during administration is separated from the diluted solution and stored in a stable state. You can also.

  Further, the void 9 formed between the lower drug storage chamber 32 and the drug discharge port 5 can prevent the occurrence of trouble that the undiluted solution leaks inadvertently from the drug discharge port 5 before administration. it can. In addition, it is possible to prevent the occurrence of troubles such as erroneous administration of undiluted stock solutions.

  Further, for example, it corresponds to an area of 1 to 25% of one side of the sheet material 1 or 2 in the drug storage chamber 32 in which the drug is stored or the drug storage chambers 31 and 32 in which the drug is stored and in communication. Even if an inadvertent pressing force acts on the vicinity of the center, the easy opening partition portion 82 that partitions the lower drug storage chamber 32 and the empty space 9 is not broken, so before administration, Occurrence of troubles such as leakage of drug (stock solution) can be eliminated.

  Furthermore, since the stock solution and the diluting solution are mixed, the easy-open partitioning portion 82 that wraps the bag body 6 from the upper part toward the lower part and partitions the lower drug storage chamber 32 and the space 9 can be broken to the fully opened state. The medicine can be prevented from remaining in the bag body after the medicine is administered with the bag body 6 suspended. Therefore, there will be no shortage of drug dose.

  As described above, if the volume of the void 9 is set to be relatively small (40% to 20% or less of the volume of the medicine), the easy-open partition 82 that encloses the void 9 with the bag body 6 involved. When pressure is applied, a large pressure can be applied, so that the easy-open partition 82 can be reliably broken to the fully open state.

  And since the upper half part of the bag body 6 is formed in a substantially isosceles triangle shape, the shape discriminating property becomes remarkable, and it can be clearly distinguished from others in appearance at first glance. This is suitable for the case where a specific medicine requiring treatment is contained. Further, since the right and left isosceles portions 71 and 71 are heat-welded, the rigidity of the isosceles portions 71 and 71 is improved, and the suspension load acting on the suspension portion 4 provided on the upper portion of the bag body 6 is heated. Evenly distributed in the isosceles portions 71 and 71 whose rigidity is improved by welding, a suspension state that is stable in strength is obtained. Therefore, even if the size is increased, it is not necessary to separately provide an auxiliary small hole as in the prior art, so that it can be suspended with good workability and a stable suspended state can be obtained. In addition, since the outer shape has a rhombus shape as a whole, there is an advantage that trimming can be performed with a high yield if the sheet is cut obliquely from the raw fabric roll.

  Moreover, since the upper half part of the bag main body 6 is formed in a substantially isosceles triangle shape, there is an advantage that the bag main body 6 can be easily caught when the easy-open partition 82 is broken. And when transporting, etc., it is folded in two at the center easy-open partition 81 and packed compactly, but as described above, the outer shape of the bag body 6 is formed in a substantially rhombus shape, There is also an advantage of easy folding.

  FIG. 3 shows another embodiment. In addition, the same code | symbol is attached | subjected about the same member as previous embodiment, and an equivalent member, and the description is abbreviate | omitted. This also applies to the other embodiments. In the present embodiment, the easy opening partition portions 81 and 82 each have a double structure, and the empty spaces 91 are respectively provided between the easy opening partition portions 81a and 81b and the 82a and 82b that are arranged in parallel with a space in the vertical direction. (9) and 92 (9) are provided. With such a configuration, it is possible to reduce the occurrence of trouble that the easy opening partition portions 81 and 82 are inadvertently opened.

  In the example shown in FIG. 4, the shading paint 15 is applied to both the front and back surfaces of the other drug storage chamber 32 for storing the stock solution or the like, or the light shielding film 15 is attached to prevent alteration of the stock solution or the like due to light transmission. I have to. When the light shielding film 15 is heat-sealed and pasted, for example, if the heat-sealing is performed at the positions of the vacant spaces 91 and 92, the easy-open partition portions 81 and 82 are not accidentally reheated and cured. , Easy patency can be ensured.

  In the example shown in FIGS. 5 (a) and 5 (b), the narrow wall 10, 10 is not formed in the void 9, but the volume of the void 9 is accommodated in the medicine accommodating chambers 31, 32. If the volume is smaller than the volume of the drug, and more preferably set to 40% to 20% or less of the volume of the drug, the easy-open partition 82 is fully opened by enclosing the bag body 6 as in the previous embodiments. It can be broken into a state. The volume of the empty space 9 can be easily set by adjusting the vertical position of the easy opening partition 82.

  In the example shown in FIG. 6 (a), the parallel parts 14, 14 are formed under the left and right isosceles parts 71, 71, and the lower part is the left and right isosceles parts arranged in a constricted shape. 72 and 72, and the narrow wall 10, 10 is not formed in the void 9, but the void 9 is formed in a tapered shape toward the medicine discharge port 5. In the example shown in FIG. 6B, the parallel parts 14 and 14 extending downward are formed below the left and right isosceles parts 71 and 71, but the diaphragm walls 10 and 10 are formed in the space 9. The void 9 is formed in a tapered shape toward the medicine discharge port 5.

  The present invention is not limited to the configuration of each of the embodiments described above, and design changes and improvements can be freely made as necessary without departing from the spirit of the invention. Combinations of configurations between these forms are also free. For example, the oblique sides 71 and 71 of the upper half of the bag body 6 formed in a substantially triangular shape may have different lengths on the left and right sides, and may not necessarily be formed in a straight line, and may be curved or wavy. Etc. Further, there may be provided three or more drug storage chambers (a plurality of drug storage chambers 31 and 32, respectively).
