Definitions
- the present invention relates to a method for transferring a substance between closed systems, wherein the closed systems, namely at least one donor system and at least one target system, are at least simply sterilized before the transfer, wherein the substance enters the target system and wherein after the transfer of the substance, the target system and the donor system are sterile separable from each other.
- the present invention relates to a device for transferring a substance between closed systems, in particular for carrying out the method, wherein the systems are mutually sterile connectable and sterile separable from each other and having means for transfer of the substance.
- sterile connection techniques such as the "sterile docking" and the "sterile Welding” are known with which thermoplastic plastic tubes of two closed systems can be connected to each other sterile and also sterile again separated.
- DOCKING is about creating cuts under the influence of temperature and directly fusing both ends of two plastic hoses.
- WELDING is about separating the connection, whereby a compression under temperature leads to the formation of a homogeneous cross-sectional area and cutting, so that two closed cut surfaces arise.
- sterile connection can also be gig of the aforementioned connection techniques such as the "sterile docking" and the "sterile Welding” by mounting and welding of plastic containers and hoses under clean room conditions and sterilization measures are produced in a known manner.
- a concrete use case for matter or a substance to be introduced into the closed system refers to stem cells obtained by apheresis of patient blood. Before a patient suffering from cancer undergoes chemotherapy, stem cells are taken from him. Only then does the patient receive chemotherapy. Since stem cells are broken down in this chemotherapy, the patient is later given the stem cells removed.
- the apheresis treatment proceeds in such a way that blood is taken from the patient and transferred to a closed system. Centrifugal forces act in the closed system, breaking down the blood into constituents. Cell populations are separated that contain stem cells in order to secure them first. The remaining blood is returned directly to the patient.
- the separated cell populations are provided according to their intended use with additives such as, for example, the patient's own plasma and foreign plasma.
- This substance which is a cell suspension, must be preserved in order to be able to supply it later to the patient.
- Preservation can only take place using the chemical compound dimethylsulfoxide, called in other DMSO, in a freezer bag for cryopreservation.
- the chemical compound DMSO serves to concentrate the cell liquid in the preparation to compensate for differences between different osmotic pressures. This protects the stem cell substance from cell destruction / bursting.
- the freezing bag consists, for example, of ethylene vinyl acetate, a plastic which is also abbreviated to the abbreviation EVA. While the stem cell preparation could be treated further under sterile conditions, the addition of the chemical compound DMSO is the weak point with regard to maintaining the closed system.
- DMSO can not be placed in bag systems by the manufacturer and subjected to a sterilizing pretreatment.
- a storage of the chemical compound DMSO is in any case longer term in chemically inert vessels, for example. Boroslicate glass, make with solvent-resistant closure.
- the present invention seeks to provide a method and an apparatus, wherein a contamination-free transmission of a substance without gas inclusions between closed systems is made possible.
- a device of the type in question is characterized in that a pressure compensation device is provided, which is flow-connected with at least one sterile system.
- the pressure equalization could take place wherever volume changes of the substance occur. As a rule, this could occur both with the encoder system and with the target system. In an application in which the donor system consists only of a sterile-coated ampoule with sterile connectable transfer means, the pressure equalization could also be completely relocated to the target system and the resulting negative pressure in the donor system can be accepted as the empty ampoule after sterile separation is disposed of by the target system.
- Essential to the invention is the realization of a volume-accurate transfer of the substance, which is achieved in that the substance is transferred dosed.
- semiquantitative dosing operations or doses by means of calibrated metering devices comprises.
- the substance could be actively transferred from the encoder system to the target system or actively removed from the encoder system.
- calibrated syringes or carpules could be used with regard to a desired dosage.
- the substance could enter the target system under the influence of gravitational force.
- a dosage could be done here via a calibrated drip chamber.
- Transmission means such as syringes, carpules, drip chambers, in turn, could form closed systems or be components of closed systems.
- the encoder system could be connected sterile with several other target systems.
- the multiple connection of the encoder system with one or more target systems could be successive or simultaneously possible. This allows a partial transfer of substance.
- the target system becomes the donor system when the absorbed substance is passed on to another target system. Either this could happen after a first sterile connection and disconnection, or the device is designed to change function by opening and closing metering gates.
- a Dosierabsperrung initially opened for receiving substance between the donor and target system is closed after filling the target system. If substance is then transferred from the filled target system to another target system by opening a further dosing shutoff, the filled target system now has a donor function.
- the substance could preferably be introduced under clean-room conditions into the donor system in a sterile manner, which is then sealed under sterile conditions to form the blister pack.
- a container could be factory-filled and sealed under clean-room conditions, then reach the laboratory doctor, who makes a sterile connection to a target system and thus can transfer the prepared substance.
- a differently stored, but equally simple embodiment provides, factory to a container without substance finished, the means for transferring the substance - here for removal - from an example. Ia- boron-side existing donor system or supplied included.
- the closed system which may be a donor system, a target system or even a system with donor and recipient function, could have a container for the substance.
- the container separates the environment from the interior of the closed system in which the substance could already be contained.
- the pressure compensation device could be materially connected to the container and be present as a rubber bag. The connection of the pressure compensation device could be welded into the container, so that the integrity of the system is not interrupted. Alternatively, the pressure compensation device could also be an integral part of the container via a special shaping process.
- the means for transferring the substance could comprise at least one port for sterile connection to at least one port of another closed system.
- the connection could be formed as a thermoplastic plastic tube.
- the connection could also be connected to the container of the system in a cohesively sterile manner.
- the connection or the plastic tube could have a length which allows a multiple sterile connection and disconnection.
- multiple connections or plastic tubing could be provided for multiple connection to another closed system or to several other closed systems.
- the container of a device could comprise a base plate.
- This base plate could consist of a rigid plastic and, for example, accommodate holding devices and / or connection points that affect the connection. So that the objects contained in the container are visible, the container could be transparent, at least in the flexible regions of the wall. The transparency allows, for example, the metered substance removal or filling and - in a specific embodiment - the placement or mounting of the transfer means within the container. Otherwise, at least the view of the existing amount of substance is released by the transparency.
- the container could also have a cover plate. Between the cover and the base plate, the flexible wall, in particular the bellows, or a sheath could extend.
- the cover plate could be arranged a stabilizing element, which contributes to the attachment of a container disposed within the receptacle for the substance during transport.
- the holding devices could be assigned to the base plate and / or the cover plate and also exercise the function as a spacer or stabilizer on the holding function.
- a particularly handling-friendly variant of the at least partially flexible container is that the flexible wall is designed in the form of a bellows.
- This bellows could be deformed strongly in all directions due to the extremely tear-resistant and thin material, which could also be stretchable. This deformation is reversible. Due to the low material thickness, objects located inside the container can be grasped, connected or positioned or otherwise manipulated. Because of the gripping movement, it is particularly important that the wall comprises at least two opposite flexible areas. With regard to the manufacture of the container, the bellows could be welded or glued sealingly on the base plate and on the cover plate.
- a further embodiment of the device according to the invention already provides for a factory-connected sterile connection of closed systems.
- the donor system could be connected sterile with a closed donor and target system in the sense of a metering device and form an overall system. It is understood that an overall system may also include more than two closed systems. It is possible after emptying the donor system to separate this sterile and dispose of it, or to use elsewhere for partial quantities. The successive separation can be done with any system with encoder function, as long as the previous encoder system is completely or as required emptied.
- Gravity-driven devices according to the invention without metering function are generally pure donor systems.
- the substance is transferred from the donor system under the influence of the gravitational force into the other closed system.
- the donor system could have a container in which the substance is contained and whose connection points in the operating position to the ground.
- the container itself could form the receptacle for the substance and, for example, be present as a collapsible flexible bag. This embodiment enables a cost-effective production and storage of substances, such as preparation solutions, at the place of use while maintaining the integrity of the systems.
- connection could on the one hand open into the container, in particular protrude minimally into the substance and be provided there with a resealable closure.
- connection could emerge from the container and be welded with its free end sterile to another system or already.
- the reclosability of the end of the connection projecting into the substance makes it possible to partially remove substances, such as preparation solutions, of course, taking into account the sterile connection and disconnection.
- the formation of the closure is a snap closure of sealing material, which is equipped with a mounting bridge and can be actuated via the flexible wall of the container.
- the attachment bridge serves for the captivity of the closure.
- the closure ensures that the substance is not introduced into the connection before the sterile connection has taken place and is possibly contaminated.
- the material of the bagged container is soft but strong enough not to be damaged during manipulation of the closure
- the container could also include in its bag form a base plate, through which the terminal is passed sealed.
- the pressure compensation device could be arranged so that it opens into the filled with air or inert gas region of the container, which always points upward in the operating position.
- a variant of the first exemplary embodiment which is suitable for the volume-accurate transfer consists in that the donor system present as a bag is already connected in a sterile manner to a donor / target system in the form of a calibrated drip chamber and forms an overall system with it. In this way, the metering device is included in the overall system as a separate closed system, which is also gravity driven. Again, the donor system could be assigned a Dosierabsperrung.
- the container may have a volume between 30 ml to 1000 ml in larger pack sizes.
- minibags reach a volume of between 10 ml and 30 ml.
- a particular, second embodiment of the device according to the invention is that it is designed as a gravity-driven metering device.
- at least two ports could be provided for the system, which include an inlet and an outlet pointing in the operating position to the ground.
- a container of the system could be provided a calibrated drip chamber, in which the substance is at least temporarily included.
- the substance is supplied via the inlet from a donor system and discharged via the outlet to a target system.
- the inlet and / or the outlet could be associated with a Dosierabsperrung.
- the inlet and outlet are sealed to the drip chamber.
- the drip chamber could be used by a base plate, a cover plate and a transparent plastic sheath between deck and base plate. With this container design, the connection of the pressure compensation device, in particular via the cover plate, could open in a sealed manner into the drip chamber.
- the calibrated drip chamber with the two sterile connectors connectable forms in the second embodiment, a closed system in terms of a gravity-driven metering device, which is both donor and target system. It is advisable that the encoder system for the above-described gravity-driven metering device also releases the substance under the influence of the gravitational force after the sterile connection of the connections into the calibrated drip chamber.
- the metering shut-off at the inlet could be used to regulate the amount of substance coming out of the donor system.
- a third embodiment of the device according to the invention which is also based on the principle of gravity, provides to arrange a receptacle in the container of the donor system in the form of a bottle or ampoule, within which the substance is located and whose closure has in the operating position to the ground.
- the receptacle could be attached to a cover plate of the container. On the outside of the cover plate, an eyelet could be provided so that the container can be hung like a drip. In one of the cover plate opposite base plate of the connection could be welded.
- the means for transferring the substance may comprise a short cannula for discharging the substance, in particular a liquid, and a long cannula for supplying air or inert gas.
- the cannulas could pierce the closure of the receptacle and protrude into the receptacle.
- the short cannula could be fluidly connected to the sterile connection in the operating position.
- a connecting piece connected to the short cannula in the form of a plastic tube could project into a larger plastic tube of the connection with respect to the cross-section.
- the connection is welded to the base plate of the container and the plastic tube connected to the short cannula sealingly passes through an opening in the base plate.
- the long cannula opens into the bellows-equipped container to which the pressure compensation device is connected. At rest, the bellows is extended and takes up the two cannulas. The cannulas are prevented by a holding device from puncturing the closure of the receptacle.
- the holding device can be supported on the base plate.
- the holding device could be in the form of a flexible slotted sleeve according to a preferred structural embodiment, which is particularly easy to handle. So long the needles are not used, they are arranged in the holding device, which protects the flexible wall of the container, the bellows, before piercing.
- the sleeve is resting in the resting state on the one hand against the base plate of the container, on the other hand against the shoulders of the recording. In the operating position, the sleeve is manipulated from the outside via the bellows, now lies around the ampoule body and the cannulas pierce the closure. The bellows of the container is thereby moved together.
- the volume of the recording could be predetermined, so that the amount removed can be estimated.
- the arrangement of a Dosierabsperrung at the connection improves the volume and time accurate dosage of the set for the other closed system amount.
- the container comprises a calibrated drip chamber.
- This drip chamber could be welded directly to the base plate of the container and with appropriate sealing and sterility of all connections and connectors be part of the encoder system.
- Both cannulas - both the long and the short cannula - are fluidly connected to the drip chamber via connecting pieces.
- the short cannula inside the container could be assigned a metering shut-off, which can be actuated via the bellows of the container. From the calibrated drip chamber, the port could exit for connection to another system, which expediently faces the ground in the operating position.
- a fourth exemplary embodiment deals with the use of a calibrated syringe with an ampoule flask and an ampoule body as a means for active metered transfer of the substance.
- the application of force can be done manually by the user.
- the syringe can also be incorporated into a known per se electromotive pumping system, in which the dosage can be programmed time and volume precision.
- the syringe could be filled within a container from a recording containing the substance out
- the ampoule body of the syringe could already be filled with substance or finally filled by pulling the syringe with substance from another donor system.
- the ampule body of the syringe forms a generally temporary receptacle for the substance, since the transfer takes place via the syringe.
- the syringe could be actuated from the outside.
- the system comprising the syringe could have a superimposed donor and target function when filling with substance and dispensing substance in the same system.
- the syringe could be arranged within the container and be actuated via an at least partially flexible wall of the container, in particular via the bellows, from the outside.
- a cannula could also be included, which can also be handled via the bellows.
- the syringe would be assembled with the cannula. Thereafter, the puncture plug of the recording would be pierced and the syringe wound up, that is filled with substance within the system. Thereafter, the cannula would be removed and the drawn syringe with a connector in the form of a tubular fitting connected to the target-oriented port.

- a complete system G + G / Z consisting of a closed encoder system G with the features of the encoder system according to FIGS. 7A, 7B and a closed system G / Z with the features shown in FIGS. 12A to 12D, comprising the encoder and the Target function is shown in Figs. 13A to 13D.
- each system G and G / Z has within the scope of the invention.
- the pressure compensation device 1 is flow-connected to the container 3 and to the long cannula 19.
- the pressure compensation device 1 is also fluidly connected to the local container 3.
- FIG. 13A shows the rest position in which the cannulas 18, 19 are still fixed in the holding device 6.
- Fig. 13B the puncture plug is already pierced, the bellows 7 of the container 3 of the encoder system G is folded and the pressure compensation device 1 filled with displaced air.
- the metering shut-off 13 on the connecting piece 15 is opened and the ampoule piston 25 of the syringe is raised, wherein the pressure-equalizing device 1 now contains less air and the volume of the bellows 7 is increased.
- the substance of the donor system G flows according to the arrows.
- Fig. 13D the suction is completed.
- the ampoule piston 25 transfers the substance in accordance with the arrows drawn from the ampoule body 26 into the connection 2 and finally to the target system Z. In this transfer, the metering shut-off 13 is closed on the side of the ampoule and opened on the side of the ampoule body.
- a fifth exemplary embodiment of the device according to the invention according to FIG. 14 deals with a calibrated cartridge as a means for transferring the substance with a carpal piston 34 and a carpal body 35 in which the substance is contained.
- the carbody body 35 is closed with a puncture stopper 20.
- the transparent container 3 containing the cartridge comprises two chambers 32, 33. Each chamber 32, 33 is fluidly connected to a respective pressure compensation device 1.
- the first chamber 32 comprises a cannula 36, which points with its tip to the puncture stopper 20 of the Karpullen stressess 35 and projects with its opposite end formed as a connector 15 in the end connector 2.
- the Karpullenkolben 34 is disposed in the second chamber 33, which includes a bellows 7 and a cylindrical portion in the form of a stable sleeve 38.
- the end of the Karpullenkolbens 34 is with glued to the cover plate 5, on which the bellows 7 is arranged.
- the bellows 7 then goes into the stable sleeve 38, which also receives the Karpullen emotions 35.
- a radially inwardly facing annular shoulder 40 is provided, against which the Karpullen stresses 35 is supported.
- the sleeve 38 also has a radially inwardly facing annular shoulder 41, which counteracts an axial movement of the Karpullenkolbens 35. While the annular shoulder 40 is already formed on the sleeve 38, the annular shoulder 41 is formed by the fact that after the introduction of the Karpullen stressess 35 into the sleeve 38, a ring is introduced into the sleeve 38, which is welded to the sleeve 38 and so the ring school - ter 41 trains.
- the first chamber 32 is welded to the annular shoulder 40 of the sleeve 38.
- the chambers 32, 33 are fluidly connected in the slightest extent, at least not sufficient to use only a pressure compensation device 1.
- the first chamber 32 has a transfer barrel 39 and therein a bellows 7 welded to the base plate 4.
