Technical Field

The present invention relates to a peritoneal dialysis system comprising at least one peritoneal dialysis machine.

Background

The patient is subjected to peritoneal dialysis at a conventional treatment site.

The treatment site may be a medical facility or clinic. Peritoneal dialysis is often performed at home or in a bedroom at home. A solution bag of fresh dialysis solution is used as part of the peritoneal dialysis treatment; the dialysis solution is introduced into the abdominal cavity of the patient via a hose system and a patient conduit and is maintained therein for a specific duration. The peritoneum serves as a dialysis membrane that enables exchange between the dialysis solution and the patient's blood in the form of waste products transferred from the patient's blood through the membrane into the dialysis solution. After a certain dwell time, the dialysis solution is drained from the abdominal cavity again.

In those cases where the patient is treated at home, in particular more logistics are required, wherein the solution bags have to be transported to home and have to be stored there in sufficient quantities. Another disadvantage is that the manufacture of the solution bag requires a certain expense, which makes the supply of the solution bag more expensive for the patient.

Disclosure of Invention

It is therefore the primary object of the present invention to provide a peritoneal dialysis system by means of which peritoneal dialysis treatment can also be carried out at home in a relatively less logistically and inexpensive manner.

This object is achieved by a peritoneal dialysis system having the features of claim 1.

It is therefore provided that the peritoneal dialysis system further has at least one water unit and at least one concentrate container for preparing and/or metering water, wherein the concentrate container has or communicates with at least one connector, and wherein the water unit and/or the peritoneal dialysis machine has at least one receiver for the connector, wherein the connector has at least one piece of information, preferably in the form of a bar code, which represents the amount of water to be filled into the concentrate container or can draw conclusions about the amount of water, and wherein the water unit or the peritoneal dialysis machine is configured to read this information and to carry out or start the addition of water on the basis of the read information.

According to the invention, it is therefore provided that one or more concentrate containers are filled with water by means of a water unit, and in this way a solution container suitable for treatment is obtained and a ready-to-use dialysis solution or a part thereof is prepared. This means that it is not necessary to transport such a solution container to the patient, but it is sufficient to provide a concentration container at the point of care (POC), which may be, for example, a room of the patient at home. The finished dialysis solution was prepared only here. This facilitates transport and storage, as the concentrate container occupies much less space than a finished solution bag or other solution container, and is lighter and less expensive.

The term "container" within the framework of the invention encompasses all conceivable containers, such as containers with fixed walls, such as boxes, or also containers with flexible walls, such as bags.

The information about how much water has to be filled into the concentrate container is located on one or more connectors which may be arranged directly on the concentrate container, but preferably at the end of a hose connected to the inner space of the concentrate container. In this respect, the information may specifically comprise the amount of water (mass, volume, etc.) or it may also be possible to obtain only indirect conclusions about the amount of water. This may occur, for example, such that the information only includes the type of concentrate, while the amount of water to be added to the concentrate to obtain the finished dialysis solution or a part of the finished dialysis solution is read from such information, for example from a storage medium.

Alternatively, other fluids, such as electrolyte solutions, may also be used to prepare the finished dialysis solution.

By "finished dialysis solution" is understood a dialysis solution that can be supplied to a patient. A "part of the finished dialysis solution" is understood to be such that the finished dialysis solution is mixed from two or more parts, for example in a peritoneal dialysis machine, i.e. in this case the finished dialysis solution is prepared in the peritoneal dialysis machine only from the parts of the finished dialysis solution.

The water unit is preferably configured to be connected to a conventional domestic water system or a conventional faucet.

Alternatively, it is also conceivable to provide a different fluid preparation device, for example in the form of a water tank or a fluid tank, instead of a water tap.

The water unit may for example comprise at least one RO unit and/or one or more filters. In the RO unit, purified water is prepared from tap water by reverse osmosis. Further purification may be achieved by further treating the water in one or more filters. They may be connected upstream and/or downstream of the RO unit.

Instead of RO units, there may also be different units to prepare pure water, such as units for deionization, units for distillation or a combination of one or more of the above units.

It is conceivable that the concentrate container is a concentrate bag and/or that at least one hose with a connector arranged on the end is located at the concentrate container. One or more hoses are in fluid communication with the interior space of the one or more concentrate containers such that water can be filled into the concentrate containers through the hoses and the finished dialysis solution or a portion of the finished dialysis solution can be drained from the concentrate containers to the peritoneal dialysis machine via the hoses or via a different hose.

Preferably, provision is made for the concentrate container to have or communicate with at least two connectors, wherein at least one of the connectors comprises said information and the other connector comprises the same information or different information, and wherein both the peritoneal dialysis machine and the water unit each have at least one receiver for a respective one of these connectors.

A preferred embodiment of the invention therefore comprises a concentrate container which is designed with at least two hoses, each hose being provided with a respective connector. One connector for connection to the water unit and one connector for connection to the peritoneal dialysis machine.

At least one of these connectors comprises the above-mentioned information which indicates or enables a conclusion to be drawn about the amount of water to be filled into the concentrate container. This information can be arranged on the connector, for example in the form of a bar code or also in the form of a different code that can be read. The water unit and/or the peritoneal dialysis machine comprises at least one receiver for receiving the connector and a reading device configured to read information on the connector.

If the water unit comprises the receptacle, and if a connector is inserted into the receptacle, the water unit can directly provide the required amount of water and meter it into the concentrate container.

If the peritoneal dialysis machine comprises the receptacle and if a connector is inserted into the receptacle, the peritoneal dialysis machine transmits information to the water unit so that it can provide the required amount of water and can meter it into the concentrate container.

In an alternative embodiment, it is also conceivable for the metering of the amount of water to be carried out by means of a peritoneal dialysis machine.

The other connector may equally be a connector provided with one piece of information or may be a standard connector that does not include any information. However, the other connector may equally be a connector comprising a piece of information, for example in the form of a bar code or in the form of a different code. The two connectors may include the same information or different information.

Preferably, the one or more concentrate containers have all substances required for peritoneal dialysis and present in the required concentration after dilution with water, wherein the substances comprise the group: electrolyte ions and at least one osmotic agent, in particular glucose, and optionally one or more buffers. In this regard, the one or more concentrates may be concentrated solutions and dry concentrates.

The peritoneal dialysis machine and/or water unit can have multiple receptacles for connectors of different concentrate containers, and/or the peritoneal dialysis machine can have at least one receptacle for a connector of a prefilled solution container.

If there are multiple receptacles, multiple concentrate containers may be connected and may be filled with water either sequentially or simultaneously. The concentrate containers may include the same concentrate or different concentrates.

It is also conceivable that there is at least one receptacle for a standard connector of a finished solution container, so that such a solution container already containing dialysis solution can also be connected.

One or more of the concentrate containers may have a first hose by means of which water can be added from the water unit to the concentrate container, and one or more of the concentrate containers may have a second hose by means of which the concentrate prepared in the concentrate container can be supplied to the peritoneal dialysis machine. The first hose may be provided with a code, in particular a bar code, comprising information about the amount of water to be added, and the first hose may be introduced into the water unit; another hose may be configured to have a standard connector for connection to a peritoneal dialysis machine. However, the hose may also be provided with a connector having information, for example about the type and amount of solution.

However, it is also conceivable that one or more concentrate containers have only one single hose, by means of which water can be added from the water unit to the concentrate container and by means of which the concentrate prepared in the concentrate container can be supplied to the peritoneal dialysis machine.

Furthermore, it is conceivable that one or more concentrate containers have at least one hose through which water can be added from the water unit into the concentrate container, wherein at least one filter and/or at least one-way valve is located in the hose. The filter effects further purification of the water with which the concentrate is diluted; the one-way valve ensures that no fluid flows from the concentrate container back to the water unit, but only in the opposite direction.

The filter and/or the one-way valve may be constructed to be disposable.

The peritoneal dialysis machine can include at least one receiver for a connector having information, and the peritoneal dialysis machine can also have a transmission device to transmit this information to the water unit. This is necessary when the connector is inserted into the peritoneal dialysis machine rather than the water unit. In this case, the receiver for the connector and the reading unit of the connector information can be omitted in the water unit.

These transmission means may be configured to transmit information in a wired or wireless manner.

One or more of the connectors may have one or more pieces of information about the type of concentrate, in particular the composition and/or its concentration.

The one or more concentrates may be present in liquid or solid form in one or more concentrate containers.

The water unit may have at least one balancing pump. This introduces the required amount of water into one or more concentrate containers.

Instead of a pump, any desired further metering unit can also be provided which preferably meters the water with an accuracy of 1%.

The water unit and/or the peritoneal dialysis machine can be arranged on a movable rack or trolley or can also be arranged in a container which at the same time serves as a base for the peritoneal dialysis machine.

Preferably, the peritoneal dialysis machines are APD machines, but any other desired peritoneal dialysis machine can be used within the framework of the present invention.

If multiple concentrate containers are connected, they may have different volumes or the same volume.

It can generally be provided that the volume of the concentrate container represents a piece of information which is likewise included in the code, in particular the bar code, of the connector. Exemplary volumes are 2L, 5L or 15L if only one bag is used for the overall treatment.

The water unit may be wirelessly connected to the platform and/or peritoneal dialysis machine, e.g., via WiFi, bluetooth, or via other techniques.

It is also possible that at least one measuring instrument is provided for detecting the weight of the concentrate container, and that communication means are present for communicating between the measuring instrument and the water unit, via which communication means information about the current weight of the concentrate container can be transmitted to the water unit. An unbalanced pump may be used. In this case, the filling volume in the concentrate container is defined via the measuring instrument. It is conceivable that the measuring instrument or another unit connected to the measuring instrument controls a valve which blocks or releases the flow path in the concentrate container depending on whether the desired volume or weight has been reached in the concentrate container. Thus, it is also possible to look at or verify a plurality of concentrate containers one by one.

In one embodiment, it is provided that the peritoneal dialysis machine has at least one memory in which a prescription to be executed for the treatment is stored. Based on the prescription, the peritoneal dialysis machine determines which concentrate containers are to be connected to the water unit. The water unit reads information from the bar code or other code about the volume amount to be used for diluting the concentrate and performs filling of the respective concentrate container or containers.

The water unit may have a device configured to issue a time stamp from which the time at which the solution is to be completely diluted may be derived. The time stamp is communicated to the peritoneal dialysis machine through a connection device (e.g., a wireless WLAN or LAN). The peritoneal dialysis machine verifies whether the timestamp is still valid, i.e. that a too long duration has not elapsed since the solution was prepared, and allows the solution to be used for treatment only if this duration has not been exceeded. Typical values are in the range of 6 to 24 hours.

For better mixing of the solution, at least one motion element, such as a vibrator, may be provided to move one or more concentrate containers.

Alternatively or additionally, pressure fluctuations may be imposed on the filling of the concentrate container to ensure better mixing.

The suction phase and the filling phase may also be used alternately.

The invention also relates to a concentrate container comprising a concentrate for use after dilution as a solution for peritoneal dialysis, wherein the concentrate container has at least one connector with one or more pieces of information, preferably in the form of at least one bar code, representing or enabling a conclusion to be drawn about the amount of water to be injected into the concentrate container. The concentrate container may have, for example, one or two hoses. In the case of two hoses, each hose may be provided with a connector having one piece of information, or with only one of the connectors, as described in more detail above.

The invention also relates to a method for preparing a peritoneal dialysis solution, wherein the preparation is carried out using a peritoneal dialysis system according to one of claims 1 to 12.

Preferably, the method is performed such that it comprises the step of introducing at least one connector into the water unit and/or the peritoneal dialysis machine, such that information located on the connector can be read and water can be added to the one or more concentrate containers according to the read information.

Further details and advantages of the invention will be explained in more detail with reference to embodiments shown in the drawings.

Shown in the drawings are:

FIG. 1 is a schematic view of a peritoneal dialysis system wherein each bag has two hoses with connectors;

FIG. 2 is a schematic view of a peritoneal dialysis system wherein each bag has a corresponding hose with a connector;

Detailed Description

Fig. 1 shows a peritoneal dialysis system according to the invention in a first embodiment.

A water unit comprising means for metering and means for treating or purifying water is designated by reference numeral 10.

The water unit 10 is connected to a tap 1 of a home or a clinic or the like.

Reference numeral 20 denotes a peritoneal dialysis machine; reference numeral P denotes a patient whose prescription is stored in the peritoneal dialysis machine 20.

Two concentrate containers of different sizes and with concentrates K30 and K31 are designated by the reference numerals 30 and 31, wherein the concentrate container 30 has a volume of 15L and the concentrate container 31 has a volume of 5L.

Both concentrate containers 30, 31 are prefilled with concentrates K30, K31 diluted with water from the unit 10.

As can be seen from fig. 1, each of these concentrate containers 30, 31 has a first hose S1 with a first connector K1 and a second hose S2 with a second connector K2, wherein hose S1 is used to supply water from the unit 10 into the bag 30, 31, and hose S2 is used to discharge diluted concentrate or finished dialysis solution from the bag 30, 31 to the peritoneal dialysis machine 20. A corresponding one-way ultra-pure filter 11 is located in hose S1.

The connectors K1 and K2 each include a barcode B1 and B2, respectively.

The bar code B1 includes information to obtain a conclusion about the volume or mass of water to be filled into the pouch 30, 31. The water unit 10 reads this information and meters the corresponding amount of water in the bag so that the desired concentration of the individual substance is present in the bag.

Once this is the case, the solution can be used in the peritoneal dialysis machine 20. The peritoneal dialysis machine 20 reads which solution is from the bar code B2 of connector K2.

The transport of the solution bag containing the finished dialysis solution can be dispensed with by the invention. It is sufficient to provide a concentrate bag or concentrate container whose contents are only diluted to the desired concentration on site.

The peritoneal dialysis machine 20 also has one or more receptacles for standard connectors so that a fully filled standard solution bag 33 can also be connected and used, as shown in fig. 1.

Fig. 2 shows an embodiment in which the concentrate container has only one hose S3, which hose S3 is designed with a connector K3 with a barcode B3. In another aspect, components that are the same or have the same function are labeled with the same reference numbers as in fig. 1.

Connector K3 is introduced into the receiver of the peritoneal dialysis machine 20 and thus connector K3 is not in direct communication with the water unit 10.

The water unit 10 comprises a pre-filter and RO unit 11, a pump such as a vane pump 12 and a filter 13 connected downstream of the pump. The water unit 10 communicates with the peritoneal dialysis machine 20 via a hose 40 or via another line. A further filter 41, for example a 0.2 μ filter, is located in the hose 40.

The peritoneal dialysis machine 20 reads the bar code B3 and reports the amount of water to be metered to the water unit 10. The water unit 10 delivers this amount of water to the peritoneal dialysis machine 20 and from the peritoneal dialysis machine 20 into the concentrate containers 30, 31. After dilution and dissolution into the concentrate containers 30, 31, the solution is delivered to the peritoneal dialysis machine or from the peritoneal dialysis machine to the patient, for example by means of one or more pumps. Reference numeral 60 designates a safety compartment in the concentrate container 30.

The bar codes B1 and B3 include information indicating the type of solution or concentrate to be prepared and the amount of water to be added. Although having the same reference number B1, the bar code B1 of pouch 30 optionally has different information than the bar code B1 of pouch 31. This applies correspondingly to barcodes B2 and B3.

The peritoneal dialysis system can be used as a batch system for preparing solutions for the respective treatments in a batch manner.

It is contemplated that the peritoneal dialysis machine or peritoneal dialysis system as a whole may be moved to the patient.

The peritoneal dialysis machine can be moved on a cart T from a filling station or from a water unit to the patient.

Fig. 3a) shows the peritoneal dialysis machine 20 and the water unit as a mobile peritoneal dialysis system, wherein the peritoneal dialysis machine 20 stands on top of the water unit 10.

Fig. 3b) shows the peritoneal dialysis machine 20 on a trolley T and independent of the water unit 10, the water unit 10 in this case being configured as an independent unit separate from the peritoneal dialysis machine 20.
