Description

[0027] There are now various possibilities for designing and developing the teaching of the present invention in an advantageous manner. For this purpose, reference is made on the one hand to the claims subordinate to claim 1 and on the other hand to the following explanation of preferred embodiments of the invention using the drawings. In conjunction with the explanation of the preferred exemplary embodiments of the invention with reference to the drawings, generally preferred embodiments and developments of the teaching are also explained. In the drawings,

[0028] FIG. 1 shows a schematic view of a first exemplary embodiment of a bag 1 according to the invention for providing patient-specific, in particular oncological drugs, and

[0029] FIG. 2 shows a schematic view of a second exemplary embodiment of a bag 1 according to the invention for providing patient-specific, in particular oncological drugs.

[0030] FIG. 1 shows a bag 1 for providing patient-specific oncological drugs, which has in its interior four separate chambers 2a, 2a, 2a, 2b, wherein three of the chambers 2a, 2a, 2a for providing an infusion solution and adding a patient-specific active substance and the fourth chamber 2b serve to provide a rinse solution. The bag 1 is made of a wide ethylene-vinyl acetate (EVA) tube, wherein a weld 3 forms the right bag wall. The inner walls 4 of the individual chambers 2a, 2a, 2a, 2b are welded together by induced heat. The chambers 2a, 2a, 2a, 2b have partially different volumes, specifically 500 ml, 100 ml and twice 250 ml. Furthermore, the chambers 2a, 2a, 2a, 2b are elongated and have on their upper side a tube inlet 5 for filling the chambers 2a, 2a, 2a, 2b and at their lower side a tube outlet 6 for emptying the chamber 2a, 2a, 2a, 2b. The active substances are added through the tube inlet 5 into the respective chamber 2a, 2a, 2a, 2b.

[0031] The tube outlet 6 is associated with a Luer-Lock tube connector 7, by means of which the bag 1 is connected to a merging system 8. The merging system 8 comprises individual tubes, each connected to a tube outlet 6, which are brought together on the ends opposite the tube outlets 6. In the region of the Luer-Lock tube connector 7, closing clips 9 made of plastic are arranged to regulate the flow. The leftmost outermost tube of the merging system 8 is assigned an injection port 10 for further injections during the treatment. At the end of the merging system 8 opposite the bag 1, an opening 11 or a port for administering the drug via an infusion line to the patient is provided.

[0032] The inside surface of the bag 1 is designed such that an almost complete emptying of the chambers 2a, 2a, 2a, 2b can be realized. Both the bag 1 and the merging system 8 are made of a photoprotective plastic to protect the drugs used from light. A clear plastic can also be used.

[0033] FIG. 2 shows a second preferred exemplary embodiment of a bag 1 according to the invention for providing patient-specific oncological drugs, with a bag 1 which in its interior has four separate chambers 2a, 2a, 2a, 2b, wherein three of the chambers 2a, 2a, 2a serve for the provision of an infusion solution and the addition of a patient-specific drug and the fourth chamber 2b for the provision of a rinse solution. The bag 1 is made of a wide and clear polymer tube, specifically made of polyolefin (POF). Around the bag 1, a photoprotective protective cover, not shown in FIG. 1, can be arranged. Both the left and right bag walls are formed by folding the tube. At the top and at the bottom, the tubular bag 1 is welded shut. The inner walls 4 of the individual chambers 2a, 2a, 2a, 2b are also formed by welding. The chambers 2a, 2a, 2a, 2b have partially different volumes. The shape of the bag 1 or the chambers 2a, 2a, 2a, 2b is designed such that an almost complete emptying of the chambers 2a, 2a, 2a, 2b can be realized. Furthermore, the chambers 2a, 2a, 2a, 2b are elongated and extend from the upper end to the lower end of the tubular bag 1. On their lower side, they each havethrough the weldsa connecting piece 5, 6, which can serve both as a tube inlet 5 for filling the chambers 2a, 2a, 2a, 2b and as a tube outlet 2a, 2a, 2a, 2b for emptying the chambers 2a, 2a, 2a, 2b.

[0034] The connecting piece 5, 6 is associated with a Luer-Lock tube connector 7, by means of which the bag 1 and the individual chambers are connected to a merging system 8. Other means of connection of the merging system 8 are conceivable. The merging system 8 comprises individual tubes, which are connected at one end to a connecting piece 5, 6 of a chamber 2a, 2a, 2a, 2b, and are merged at the end opposite the connecting piece 5, 6 into a single tube. In the area of the Luer-Lock tube connector 7 or in the area before the merger of the individual tubes, each tube is provided with plastic closing clips 9 for regulating or opening and closing the flow. The left-most tube of the merging system 8 is assigned an injection port 10 for further injections during a treatment. At the end of the merging system 8 opposite the bag 1, an opening 11 or a port for administering the drug via an infusion line to the patient is provided. In the opening 11, a silicone plug is provided.

[0035] Frequently, the tube system 8 is pre-filled before the administration of the liquids or active substances located in the chambers 2a, 2a, 2a through the opening 11 with saline, so that the patient is supplied with sufficient liquid/saline. Since the contents of the individual chambers 2a, 2a, 2a are generally not allowed to mix, they are administered to the patient one after the other. For this purpose, the administration of the liquids of the individual chambers 2a, 2a, 2a, 2b is controlled by the closing clips 9 and between the administration of two liquids or active substances at least the last section of the merging system 8, in which the individual tubes connected with the chambers 2a, 2a, 2a, 2b are merged in a tube, is rinsed with rinse solution, in particular with saline.

[0036] With regard to further advantageous embodiments of the bag according to the invention, reference is made to avoid repetition to the general part of the description and to the appended claims.

[0037] Finally, it should be expressly understood that the above-described embodiments of the bag according to the invention are merely for the purpose of discussion of the claimed teaching, but this is not limited to the exemplary embodiments.
