Definitions
- Dispensing unit process for its manufacture and its
- the invention relates to a delivery unit with a flexible polymer bag, a connecting part and an inflexible hard part, the connecting part having an inner polymer layer welded to the hard part and an outer polymer layer welded to the inner material of the flexible bag, processes for their production and theirs Use.
- Dispensing units of this type are used for the storage and dispensing of liquids and are in particular physiologically harmless heat-sterilizable bags which are made of transparent polymers, such as polyolefin materials, and have at least one hard part which can be sterilized and connected to the bag material via a connecting piece that is - ie that the welded connection between the bag and the hard part easily withstands (steam) sterilization temperatures of at least 121 ° C.
- the bag should be transparent so that changes in the liquids therein, such as flocculation, cloudiness, etc., can be recognized immediately.
- Such bags are used, for example, in medicine as blood bags, bags for dialysis fluids, plasma, etc., but may also be suitable for other aqueous solutions, such as drinks, etc.
- PVC is problematic in terms of disposal due to the occurrence of chlorine compounds during combustion, and attempts are therefore being made to replace it with non-halogenated compounds. So far, however, it has been very problematic to achieve the favorable properties of PVC, namely the very good and easy weldability and transparency with high liquid tightness and good water vapor barrier properties with other materials with economically justifiable effort.
- connection piece Because the weld seam is first produced between the connection piece and the polycarbonate part and only then is the vinyl acetate / polyethylene copolymer crosslinked so that the connection can withstand the high sterilization temperatures, the bag is sterilization-resistant. For the cross-linking of radiation, however, considerable effort is necessary, since all the complete delivery units have to be brought to a corresponding radiation source and treated there.
- a tube material for connection to the patient or for introducing additional material into a flexible bag which can possibly be welded to a polycarbonate hard part, has become known as a 3-layer tube-like material, the outside with polycarbonate by Ultra ⁇ sound, microwaves or heat is sealable.
- This sterilizable tube has an outer layer with polypropylene, ethylene-propylene copolymer or an ethylene-propylene copolymer modified with a thermoplastic elastomer, which is sealable with polycarbonate, while an intermediate layer, which makes the connecting piece flexible, is a very low density propylene , Ethyl vinyl acetate copolymer, modified or unmodified ethylene-methyl acrylate copolymer, polyvinylidene chloride, ethyl vinyl acetate and modified ethylene-methyl acrylate copolymer, a mixture of ethyl vinyl acetate and very low-density polyethylene or a modified ethyl vinyl acetate ; the inner layer should have a heat-resistant polymer material, such as a copolyester, polypropylene, ethylene-propylene copolymer, polyurethane, PVC, or a mixture of a copolyester with ethyl vinyl acetate.
- a material is preferably used for the tube, which has already been cross-linked via chemical crosslinking agents during the coextrusion to improve the temperature resistance (sterilizability) of the welded joint, or which can subsequently be crosslinked by radiation, since otherwise the material does not retain its properties under sterilization conditions and dissolves.
- This known connecting part is designed for the external connection with polycarbonate and has a complicated structure - the connection to the flexible bag is. This is therefore not a connection piece, but rather a hose for liquids which is to be connected to the polycarbonate part and which, of course, must be autoclavable.
- EP-A-56 42 31 proposes a coextruded connector for the problem of connecting a flexible bag to a polycarbonate hard part, which provides a polyolefinic polymer material as the outer layer, which has a melt flow index of about 12.
- the inner layer is here bound to an intermediate layer, which gives the connector part flexibility and can be, for example, SBS, and is designed as a connector layer containing ethyl vinyl acetate for attachment to the polycarbonate.
- This arrangement again requires the usual measure of cross-linking the bag after the connection part has been welded on, for example by radiation, in order to make the arrangement sterilizable.
- WO / 93/23108 (BAXTER) relates to the problem of a connection piece for flexible bags with PVC, which is extruded here in three layers and has a polypropylene copolymer / styrene / ethylene / butylene / styrene copolymer mixture and an inner layer as the outer layer PVC has.
- PVC polypropylene copolymer / styrene / ethylene / butylene / styrene copolymer mixture and an inner layer as the outer layer PVC has.
- PVC is mostly undesirable for the reasons mentioned above.
- the invention relates to the problem of connecting multilayer bags with a polyolefin inner layer with a hard part, these bags should be sterilizable, but the production should be greatly simplified.
- the invention relates to a method for
- the invention also relates to the use of the dispensing unit according to one of the preceding claims as a dispensing unit for liquids, in particular water-containing liquids for human or veterinary medicine or food purposes.
- the co-extruded connector is a high EVA-containing polyethylene Has inner layer and is alone radiation crosslinked before sealing.
- the hard part is a polymer, such as polycarbonate, a polyacetal, or else polyethylene.
- connection part since now only the inner layer of the connection part must be suitable for attachment to the hard part, the corresponding connection olefin usually having to be cross-linked, in particular radiation cross-linked in the polycarbonate that is frequently used, it is possible to subject only the connection parts themselves to the complex cross-linking process, while the bags can even be made from inexpensive, relatively thermally stable polyolefins.
- connection part which have high EVA-containing polyethylene as the inner bag material and also as the outer part of the connection part, to the irradiation operation via road, train, but only the connection parts, which additionally increases the manufacturing costs and reduces the environmental impact.
- the inexpensive polypropylene which naturally has a high melting temperature (140-160 ° C.)
- the bag material can be used as the bag material.
- significantly higher sterilization temperatures can be used - in particular, steam sterilization of the bags is unproblematic, which can simultaneously lead to shorter sterilization times.
- ethylene vinyl alcohol can be used as a barrier layer, which seals very well against oxygen, nitrogen, CO 2 and other gases.
- a further layer e.g. polyethylene
- a further layer e.g. polyethylene
- SiOx or aluminum oxide can be coated with SiOx or aluminum oxide using thin-layer technology.
- polyamide / polyethylene composite films can also be used as bags, as has been the case up to now - however, through the selection of the connecting parts according to the invention in combination with the other materials, radiation crosslinking of the entire bags can also be avoided become.
- the flexible bag PVC, polyethylene, polypropylene, polyamide and their compounds, in particular those with thermoplastic elastomers, such as SEBS compounds made of them or multilayer composite films made of the same, such as polyethylene / ethyl vinyl acetate, PA / polyethylene, polypropylene - len / SEBS etc. It is advantageous if the bag is produced, for example, by coextrusion - it can but all manufacturing processes familiar to the person skilled in the art are used.
- the connecting part prefferably has an inner layer forming a heat-sterilizable compound with polycarbonate, such as, for example, crosslinked polyethylene containing high ethyl vinyl acetate or else PVC, which as the inner layer practically does not come into contact with the material or liquid in the bag and therefore on it Point, since it is only used as a connecting material, is relatively unproblematic.
- polycarbonate such as, for example, crosslinked polyethylene containing high ethyl vinyl acetate or else PVC
- a delivery unit according to the invention can be manufactured in such a way that a sterile polymer bag is produced in a manner known per se, for example by coextrusion in the case of a multi-layer bag, or the like, independently of which a multi-layer polymer connecting part is produced in the form of a tube - for example by coextrusion the outer material of which can be welded to the inner material of the bag and the inner layer of which can be welded to the outer material of the hard part, this connecting part possibly being crosslinked by radiation in order to make it sterilization-resistant, a hard part being produced from a material which can be welded to the inner material of the connecting part, and then the hard part is welded to the connecting part and this is welded to the inside of the bag, so that a welded connection is created which can withstand high temperatures, such as usual sterilization temperatures.
- Dispensing units of this type are particularly suitable for storing medical liquids, such as dialysis liquids, solutions for artificial nutrition, blood, plasma, etc.
- the flexible bag preferably has PVC, polyethylene, propylene, polyamide and compounds made thereof or multilayer composite films made of the same, such as polyethylene / ethyl vinyl acetate, polyamide / polyethylene.
- the multi-layer polymer tube of the connecting part can, for example, have an outer layer made of polyethylene, PVC, the multi-layer polymer tube and the flexible bag being sealed to one another.
- connection part 1 a longitudinal section through the connection area of a connection part, hard part and the bag
- Fig. 3 is a representation of a complete bag made according to the invention.
- a preferred embodiment of a dispensing unit according to the invention has a bag made of multilayer film, which has a sealable polyolefin, such as polypropylene or polyethylene, a polypropylene compound or the like, forming seal seams as the inner layer at sterilization temperatures owns.
- a sealable polyolefin such as polypropylene or polyethylene, a polypropylene compound or the like
- the connecting part which is designed here as a two-layer polymer tube, has as the outer material 10 a polyolefin which can be welded to the inner layer material 30 of the bag, such as polypropylene or polyethylene, a polypropylene compound or the like, and is the same with the inner layer 30 Bag film welded.
- a polyolefin which can be welded to the inner layer material 30 of the bag, such as polypropylene or polyethylene, a polypropylene compound or the like, and is the same with the inner layer 30 Bag film welded.
- connection part has a high-ethyl vinyl acetate-compounded polyethylene copolymer which, after cross-linking with radiation, can be welded to a polycarbonate part 20 in such a way that it forms a sterilization-resistant, liquid-tight weld seam and its flexibility and elasticity even after sterilization maintains.
- the polycarbonate tube is now welded into the already cross-linked radiation part.
- Co-extruded two-layer bags with an outer layer of polypropylene and one using the same thermoplastic Elastomers, such as polypropylene compounded in the outer layer of the connecting part as the inner layer, are then connected by means of high-frequency welding to the cross-linked connecting tube by means of high-frequency welding.
- a polycarbonate hard part with a tube extension is inserted into the connecting part in a manner known per se and then sealed with it.
