Technical Field

The invention relates to a concentrate container with a concentrate which is designed to form a dialysis solution after dilution thereof with a diluent, in particular with water.

Background

In peritoneal dialysis it is common to administer the drug in a pre-prepared dialysis solution. The dialysis solution is typically administered in an amount of 3 to 6 liters. In a typical peritoneal dialysis treatment 3 bags are required each day, which means a significant logistic expenditure and a large storage space.

Disclosure of Invention

The object on which the invention is based is to provide a concentrate container which enables simple solution preparation with low storage requirements.

This object is achieved by a concentrate container having the features of claim 1.

Hereby it is proposed that the concentrate container is connected with a first connector having a first code, and that the concentrate container is further connected with a second connector having a second code different from the first code, said first code containing at least one piece of information about the concentrate, wherein said second code contains at least one piece of information about the dialysis solution.

Such concentrate containers require a significantly smaller volume than containers filled with the finished dialysis solution. The concentrate can be diluted with a diluent on site, i.e. at PoC (point of care), e.g. at home, so that a dialysis solution is produced from the concentrate. It is to be noted here that the term "dialysis solution" is to be understood as a solution ready for administration as well as a solution which has to be further diluted or mixed in order to obtain the finished dialysis solution.

The first connector has a first code and the second connector has a second code different from the first code. The first code contains at least one piece of information about the concentrate, such as the amount, composition or type of concentrate, amount of diluent required, etc. The second code contains at least one piece of information about the dialysis solution, such as the amount, composition, concentration, etc. of the dialysis solution.

If the concentrate is diluted, the first code is read for this purpose, so that the device performing the dilution knows the amount of diluent etc. and can add the corresponding amount.

If the dialysis solution is prepared from a concentrate by dilution, the information of the second code is read, so that it is known, for example, which solution is involved.

It is thus possible to carry out the preparation of the dialysis solution and the administration of the prepared dialysis solution by means of two codes, wherein the codes preferably contain all the main information required for the preparation of the dialysis solution and for the administration thereof, so that the risk of errors, for example due to incorrect dilutions, confusion of solution bags, etc., is minimized.

Preferably, it is provided that the first connector and the second connector can be separated from each other, for example by disconnecting.

Preferably, the first and second codes are bar codes, respectively. The bar code is preferably designed to be circumferential, so that it is immaterial in which orientation the connector is positioned during reading.

It is conceivable that there is a desired breaking point between the first connector and the second connector. In this case, the first code is first read and the dialysis solution is then prepared from the concentrate by adding a diluent, in particular RO water (RO: reverse osmosis). If the process is ended, the first connector is disconnected and the second connector is inserted into the receptacle of the dialysis device, preferably of the peritoneal dialysis device, and read there. Thus, there is information in the dialysis apparatus about what dialysis solution is involved.

Preferably, it is provided that the two connectors are arranged one after the other, so that after the preparation of the dialysis solution, the two connectors and thus the two codes can be separated from one another, so that a concentrate container coded by the second code, which contains the dialysis solution, is then directly available for treatment.

The first connector and the second connector can be connected to each other by a plug connection or a cover connection. It is thus conceivable, for example, to plug the second connector onto or into the first connector after the dialysis solution has been prepared. If the concentrate container with the prepared dialysis solution is subsequently connected to the dialysis device, the second code will be read instead of the first code.

Preferably, the two connectors are arranged adjacent to each other.

It is conceivable that the first code is spatially arranged further from the concentrate container than the second code. After the dialysis solution is prepared, the first code can be separated out so that only the second connector remains on the concentrate container, whose code can then be read.

In principle, the connector can be provided directly on the concentrate container. Preferably, the connector is arranged on the pipe section, in particular on a hose, the cavity of which communicates with the inner space of the concentrate container. Through which the diluent is introduced into the concentrate container, and from which the dialysis solution is also led.

Furthermore, a line can be provided which extends between the one or more connectors and the concentrate container, wherein a connection, in particular a luer connection, is located in the line, by means of which connection the concentrate container can be separated from the one or more connectors. This can be achieved: the emptied concentrate container can then be used as a drainage container. For this purpose, a connecting element, which can be designed as a plug connection, for example, is opened, so that the connector is separated from the concentrate container.

The concentrate container containing the connector with the code can be provided as a complete unit or can be supplied separately. By connecting the individual components of the concentrate container or of the mixing bag, the possibility of varying the size of the finished solutions and the bag or container size for different degrees of concentration is increased, without having to stock the unit itself (concentrate container or mixing bag) for each possible finished solution.

In principle, a sterile cap for the connector can be provided to prevent bacterial contamination or contamination.

It is envisaged that the concentrate container is rigid. In principle, however, the invention also includes: the concentrate container is a container with a flexible wall portion, i.e. a bag.

Combinations of the described embodiments are also conceivable and encompassed by the present invention.

It is therefore possible in the sense of the present invention for the concentrate container to have a plurality of containers, to be precise in the form of a concentrate container containing the concentrate and a solution container for holding the dialysis solution. The two are in fluid communication with each other such that the solvent, in particular RO water, can first be thoroughly mixed with the concentrate in the concentrate-holding container and such mixture, i.e. dialysis solution, can then be conducted into the solution container. The concentrate-containing container has a first connector with a first code and the solution container has a second connector with a second code.

Thus, the term "concentrate container" is to be understood as not being mandatory: exactly one container is provided. A plurality of containers can also be provided.

The concentrate holder is preferably designed as a rigid container (cartridge) and/or the solution holder as a bag for holding the mixed solution, i.e. the dialysis solution. The strong wall of the cartridge prevents: the solvent or undiluted concentrate is pumped into the dialysis equipment, since it is not feasible to extract the volume from an incompletely filled, robust container. Additionally, the corresponding suction pressure can be used as an indicator for closing or not blending with an empty bag or with a solution container when attempting to extract.

The two containers can be connected by means of a coupling. By connecting the two components, the concentrate-containing container is opened on the bag side or on the solution container side.

The shaping of the inlet or outlet opening of the concentrate-containing receptacle can assist in the mixing of the solution with the concentrate.

The concentrate-holding container can function as an air separator.

In a preferred embodiment, the solution container, which is preferably designed as a bag, serves several functions: by means of its closed system, the solution container breaks through the connector part on the cartridge or concentrate container, which contains the mixture, i.e. the dialysis solution, which is released during the treatment and which is used as a drainage bag in the next treatment.

The concentrate-containing container is preferably connected to a first connector having a first code and the solution container is connected to a second connector having a second code. Here, the two connectors can be located on the same side or on different sides of the concentrate-containing container. Preferably, the solution container is releasable together with the second connector from the concentrate-containing container, for example in the manner: the second connector is disconnected or otherwise separated from the concentrate-containing vessel.

Preferably, the concentrate container is a disposable item.

It is conceivable that the dialysis device or the dilution apparatus has a connector strip in which one or more connectors are accommodated and that the rigid concentrate container is mechanically supported by the connector strip. Preferably, this also applies to the mentioned rigid concentrate-containing containers.

The invention also relates to a dialysis device, in particular a peritoneal dialysis device for carrying out a dialysis treatment or a peritoneal dialysis treatment, wherein the dialysis device has at least one receptacle for a first connector and/or a second connector of a concentrate container according to one of claims 1 to 12 and a reading device for reading information of a code located on one or more connectors, wherein the dialysis device is designed to discharge a diluent into the concentrate container and/or to draw a dialysis solution out of the container in accordance with the code.

The dialysis device can have a pump device by means of which diluent, in particular water, is fed into the concentrate container. It is conceivable that the dialysis device is connected to a water supply line and that the dialysis solution is prepared by means of the mentioned pump means.

The same or a different dialysis device, in particular a peritoneal dialysis device, has a reading mechanism for reading the second code, so that the dialysis solution is delivered into the abdominal cavity of the patient by means of the pump mechanism.

Within the scope of the present invention, the term "dialysis device" is preferably understood as a peritoneal dialysis device. However, the term or the invention is not limited thereto and also comprises other types of dialysis equipment. The peritoneal dialysis device can be a peritoneal dialysis device in which solution or diluent is delivered by a pump or flow is achieved gravimetrically, i.e. without the use of a pump.

The invention also relates to a method for preparing a dialysis solution, in particular a peritoneal dialysis solution, wherein a concentrate container according to one of claims 1 to 12 is connected to a dialysis device by means of a first connector, such that a first code is read by the dialysis device, and a diluent is introduced into the concentrate container according to this first code, and then the first code is removed or covered, and the concentrate container is connected to the same or a different dialysis device by means of a second connector, such that a second code is read by the dialysis device.

It is conceivable that the first connector is disconnected or connected to the second connector or covered by the second connector after the concentrate has been diluted. Thus, after dilution, the second connector can be read, the code of which contains information about the dialysis solution prepared by dilution of the concentrate.

It is noted herein that the terms "a" and "an" mean, without limitation: it relates to exactly one of the elements in question, although this is a preferred embodiment of the invention. Rather, use of the term also encompasses a plurality of elements. The following applies accordingly: the use of terms in the plural also includes the singular and vice versa, and the use of terms in the singular also covers the plural of the elements discussed.

Detailed Description

It is to be noted that in the figures, identical or functionally identical elements are provided with the same reference numerals.

In the embodiment according to fig. 1, a concentrate container is shown with reference numeral 10, in which a liquid or solid concentrate K is located.

The concentrate container 10 is connected with a hose line 20, at the end of which there is a first connector K1 with a first code C1.

In a dilution station, which is formed, for example, by a peritoneal dialysis device or also by another unit, water is introduced into the interior of the concentrate container 10 via the hose 20 and, in accordance therewith, the concentrate is diluted. The dilution station reads the first code C1 and performs the dilution according to the first code. After dilution, the connector strip of the dilution station is opened and the connector or connectors K1 with the connected bags 10 or other concentrate containers 10 are removed and closed by a lid K2 with code C2. The code C2 contains information about the diluted concentrate, i.e. the dialysis solution.

Codes C1 and C2 are barcodes. Other codes are also possible, such as a different color code for the connector.

These so coded bags or concentrate containers are now capable of administering medication to a patient.

In fig. 2, the bag coupler or connector is expanded with another connector. Here, the connector K2 provided close to the concentrate container with the code C2 is connected via the desired breaking point S to the connector K1 provided further away from the concentrate container with the code C1.

The connector K2 close to the bag or its code C2 contains information about the diluted concentrate, i.e. the dialysis solution, and the connector K1 remote from the bag or its code C1 contains information about the undiluted concentrate.

After dilution of the concentrate K, the connector K1 is disconnected, so that the concentrate container now with the connector K2 can be provided for treatment.

As can be gathered from fig. 3, in the embodiment shown here the peritoneal dialysis device P is used as a dilution station in order to provide the other peritoneal dialysis devices with the prepared solution. By means of the bar code C1, the dilution station identifies the type of concentrate and adds the required amount of water.

As can be seen from fig. 3, by coupling a plurality of concentrate containers to the same apparatus, a plurality of concentrate containers (here six concentrate containers) can be manufactured simultaneously or sequentially during the mixing process.

For this purpose, the patient line L is connected to a solvent supply (for example an RO water plant). After mixing, the bag or concentrate container is loosened at the predetermined breaking point (see fig. 2 and 3, reference sign S) and is now immediately available for administration, while other mixtures can be prepared.

One conceivable embodiment consists in mixing large volume quantities in order to be able to supply a plurality of devices. After mixing the bag or concentrate container, the used kit is no longer used for treatment.

It is also conceivable to add a valve to the connector, which valve only enables the liquid to be fed into the connected bag. Thus, accidental inhalation is excluded.

In the embodiment according to fig. 2, at the beginning of the filling of the concentrate container, both connectors K1 and K2 are connected to the concentrate container, as can be gathered from fig. 2. After filling the bag, the connection between the connectors K1 and K2 is released, for example by breaking.

By this process the concentrate container becomes a clearly identifiable solution bag containing the dialysis solution.

Fig. 4 shows a concentrate container, in the hose line of which an additional connection V is provided. Thus, the concentrate container can also be used as a drainage bag after treatment.

A volume indication in the form of a measuring scale on the bag or concentrate container is indicated with reference sign a. The volume specification enables an additional visual inspection of the filled bag after removal from the filling station, for example so that the bag has to be filled to a certain level.

It is conceivable to provide the concentrate container with an additional handle, which makes it easy to transport, in particular in the case of larger liquid quantities.

In the embodiment according to fig. 4, the concentrate is present in the concentrate container in the form of a package. The package is identified by reference numeral 100. The package degrades upon contact with the diluent and is preferably located at the inlet of the concentrate container. An optimal thorough mixing with the solution can thus be achieved during filling.

In a further conceivable embodiment of the invention, the concentrate is colored with a harmless dye. This enables a check: whether the concentrate and diluent are thoroughly mixed.

In an advantageous embodiment, the invention provides the following advantages:

the solution bag or concentrate container can be taken out of the dilution apparatus immediately after being made, while the next bag or concentrate container is filled in the meantime.

The solution bags or concentrate containers can be diluted and withdrawn in a temporally staggered manner, so that the maximum optimum utilization of the consumption time period can be achieved.

Fig. 5a) shows an embodiment in which the concentrate container has two containers, namely, on the one hand, a concentrate holder 100 with a first connector 101 with a first code and a solution container 200 with a second connector 201 in fluid communication with the first connector. The concentrate 102 is located in the concentrate-containing vessel 100. The two containers are connected to each other by a connecting member 300. Through this connection, the concentrate-containing container 100 is opened toward the bag 200.

Fig. 5b) shows an embodiment in which the outlet of the concentrate container 100 opens into a bar code section or connector 201, to which a bag section can be connected or connected 201.

As can be seen from fig. 5c), a valve 400 can be provided, which only enables the input of liquid via the cartridge 100 into the connected solution bag 200. Thus, inhalation of the concentrate is prevented in terms of structure. After filling the solution bag, the connection between the containers is interrupted at 500.

At the start of filling, a common empty bag is attached to the cartridge 100. After filling the bag, the connection between the cartridge 100 and the barcode section 201 is released. By this process the common empty bag becomes a well-defined solution bag, which can now be dosed by means of the second circulator.

Thus, the solution bag can be taken out of the dilution apparatus immediately after manufacture, while the next bag will be filled. Furthermore, the solution bags can be diluted and withdrawn in a temporally staggered manner in order to maximize the use of the consumption time period.

Some scenarios are presented below, which are exemplary in nature and do not limit the invention.

Scene A：

The circulator, i.e. the peritoneal dialysis apparatus, is connected with a solvent supply, similar to in HD environments, for which a bag coupling (port) of the kit is required.

Other ports can be occupied by the cartridge. The cartridge is connected to an empty bag, typically 6 l.

The treatment process can be started immediately after the mixture is generated.

Scene B：

The circulator is connected with a solvent supply device. To this end, a bag coupling (port) of the kit is required.

Only one port is occupied by concentrate. The cartridge is connected to a bag capable of containing the full therapeutic amount.

This has not been feasible so far, as the patient does not have to transport the filled bag. This reduces the cost and waste of the disposable.

Scene C：

It is also feasible to combine the method with a conventional solution bag, which can be used within the treatment.

Scene D：

The patient lines are now connected to a solvent supply. Thus, up to six bags may be mixed in the first step.

In a second step, the patient is administered with the mixed solution without changing the kit.

Scene E：

The circulator serves as a dilution station to provide solution to other circulators. It is therefore possible to manufacture six bags in one mixing process.

For this purpose, the patient line is currently connected to a solvent supply. After mixing, the bag is released from the cartridge and provided for administration. One advantageous design of the system consists in mixing large volume quantities. As the kits used in the mixing devices are not available for treatment. A cartridge suitable for this can be seen in fig. 5 b.
