Definitions
- the present invention relates to a dialysis machine, in particular a peritoneal dialysis machine.
- PD peritoneal dialysis
- solution bags which are filled with a dialysis solution suitable for the patient.
- the dialysis solution typically needs to be transported to the patient's preprocessed state, which may entail logistical problems associated with transporting the bags to and within the patient Storage of the bags may lie with the patient.
- This object is achieved by a dialysis machine, in particular by a peritoneal dialysis machine having the features of claim 1.
- the dialysis machine comprises a device for the production of dialysis solution, so that the supply and storage of bags containing the dialysis solution may be omitted. Rather, it is sufficient to provide the patient with the concentrate (s) needed to produce the ready-to-use dialysis solution.
- Said means for producing the dialysis solution comprises a RO equipped with a filter for providing RO water and a mixing device which is adapted to mix a dialysis concentrate with the RO water or with a solution containing RO water.
- the dialysis solution especially the peritoneal dyslique solution, is thus prepared on the dialysis machine itself by mixing RO water with one or more concentrates.
- RO water can be mixed with one or more concentrates.
- the RO system is preferably an integral part of the dialysis machine, but can also be designed as a separate unit which is in fluid communication with the dialysis machine so that the RO water produced reaches the dialysis machine.
- RO water is mixed with one or more concentrates in the mixing device or that a solution which contains RO water but does not consist only of RO water is mixed with one or more concentrates.
- this RO-water-containing solution may contain one or more ingredients, such as electrolytes, an osmoticum, etc., that have already been added to the RO water before further ingredients or concentrates are added to make the ready-to-use dialysis solution.
- RO water is understood to mean the water obtained, for example, from tap water by reverse osmosis (RO), ie by the operation of the RO plant.
- the dialysis machine has a control device which is designed to operate the RO system continuously.
- the continuous operation of the RO plant i. the continuous supply of water to the RO system and / or the continuous removal of RO water from the RO system prevents clogging or contamination of the filter. It is essential that the filter of the RO system is continuously flowed through.
- the Welteren a storage container is provided, which is connected downstream of the RO system and which is adapted to store the water generated in the RO system.
- the storage tank receives the water generated in the RO system and prevents or delays in this way that the RO water must be discarded when no dialysis solution is needed. This is only necessary if no dialysis treatment is carried out for a long period of time and the storage container is full. Discarding RO water can be prevented or at least reduced to a minimum by suitable dimensioning of the storage tank.
- the storage container has a volume, so that at least one complete peritoneal dialysis treatment can be carried out with several enemas.
- the present invention not only the advantage is achieved that can be dispensed with the use of dialysis solution bags, but also the advantage that the probability of contamination or contamination of the RO system can be reduced by their continuous operation compared to an intermittent mode of operation.
- continuous operation does not necessarily mean that the RO system is permanently in operation, ie 24/7, although this is also a conceivable embodiment of the invention In any case, understand that the RO system is also in operation, if no dialysis treatment takes place or if no dialysis solution is needed or produced.
- the storage container may be connected upstream of the mixing device.
- the storage container itself forms the mixing device or a part of the mixing device, i. that the mixture takes place in the storage container itself. This is the case if the storage container already contains one or more ingredients or concentrate (s) and / or if the storage container has one or more connectors to which one or more dialysis concentrate containers can be connected or connected.
- a conduit leads away from the storage container, which serves for connection to the patient, the conduit having a connector to which a Dlatysekonzentratbereheatter is connected or connected.
- a Dlatysekonzentratbereheatter is connected or connected.
- This may be, for example, a glucose container or an electrolyte container, etc.
- the mixing device is formed by the line itself or by the part of the line in which the running out of the Dlalyse- concentrate container meets the flowing through the conduit solution.
- a sterile filter is arranged in the line which serves to connect to the patient.
- the connector (s) have a screw connection by means of which the dialysis concentrate container or containers can be connected.
- the connector has a membrane and a mandrel for piercing the membrane when making the connection when connecting the dialysis concentrate container.
- the fixing of the two parts connected to one another relative to one another can likewise be effected in this case by screwing or else by latching, by a bayonet lock, etc.
- a line from the storage container, which serves for connection to the patient, wherein the line is in communication with a mixing container.
- the RO water or RO water-containing solution flows through the conduit into the mixing vessel and is mixed therein with one or more concentrates, etc.
- the dialysis concentrate or concentrates may, for example, be an osmotic agent, in particular glucose and / or electrolytes.
- the storage container is formed by a tank or the storage container comprises a tank, wherein it is preferably provided that the tank is partially or completely formed with rigid walls.
- the storage container is preferably formed by a bag or comprises a bag, wherein the bag preferably consists of a flexible and / or elastic film or has a flexible and / or elastic film.
- The- This bag may be discarded or sterilized after treatment or replaced with a new, sterile bag.
- the storage container comprises a tank, preferably with one or more rigid walls, and a bag, the bag being received in the tank, the bag preferably being dimensioned to be so in the filled state rests against one or more inner sides of the tank.
- the flexible or elastic film of the bag can therefore be dimensioned so that it partially or completely fills the preferably rigid tank structure, i. directly against the inside of the wall of the tank.
- the sterilization agent can be, in particular, a UV irradiation device by means of which the inside of the storage container can be sterilized.
- the storage container has a fitting volume in the range of 5 to 100 l, preferably in the range of 10 to 50 l.
- the present invention relates to Welteren a dialysis machine, in particular a peritoneal dialysis machine, with a device for the production of dialysis solution, the device having a filter equipped with a RO system for providing RO water and a mixing device which is formed, a dialysis concentrate with the RO water to be mixed, wherein a control device is provided, which is designed to operate the RO system continuously, wherein the control device is adapted to operate the RO system with lower throughput when the dialysis machine is not in use and with higher throughput when the dialysis machine is in use.
- a continuous operation of the RO system can be ensured, wherein the throughput through the RO system the current adapted, ie is made dependent on whether mitteis the dialysis machine, a treatment is performed or not or whether dialysis solution is needed or not.
- the dialysis machine according to this embodiment of the invention may have one or more features of claims 1 to 14.
- the dialysis machine according to the invention is a home dialysis machine, preferably a home peritoneal analyzer, i. i.e. to a dialysis machine, which is preferably used at home in the patient.
- a dialysis machine preferably a peritoneal dialysis machine
- a mobile treatment device such as e.g. in a truck, bus or the like
- the mobile treatment facility having one or more dialysis machines by means of which patients can be treated in the mobile treatment facility.
- the mobile treatment facility may be any motorized land, water or air vehicle.
- the present invention further relates to a method for providing a dialysis solution in a dialysis machine according to any one of claims 1 to 15, wherein the RO system is continuously in operation.
- the RO system can be controlled such that the throughput of the RO system is independent of whether a treatment is performed by means of the dialysis machine or alternatively controlled such that the throughput of the RO system depends on whether by means of the dialysis machine a treatment is performed or not.
- FIG. 1 a schematic view of a peritoneal dialysis machine according to FIG.
- Figure 3 a schematic view of the storage container of a dialysis machine according to the invention.
- Figure 1 shows by reference numeral 100 in a schematic representation of a PD device according to the invention.
- Reference numeral 10 designates an RO system which is connected by a filling connection (not shown), e.g. is supplied with tap water.
- the RO plant preferably comprises one or more pumps, filters, membranes, etc. which are not shown in the figure.
- RO water is produced and transferred from this by means of the line 40 and a pump, not shown, into the storage container 20.
- the storage container 20 communicates with a feed line 40 from the RO system 10 and with a discharge line 40 ', which leads to the patient designated by the reference symbol P in FIG.
- the reference numeral 50 En FIG. 3 designates a drain line, by means of which the RO water present in the storage container 20 or a solution containing RO water can be conducted into a drain. This occurs when the level in the reservoir 20 has exceeded a certain level and the RO water is not needed to make dialysis solution.
- the control of the fluid flows by means not shown valves, which are preferably also controlled by the control device.
- the RO system 10 is operated continuously. It therefore always falls to RO water, which first enters the storage container 20.
- the storage container 20 can be designed as a tank with rigid walls, in which there is a replaceable bag into which the RO water is introduced, so that this comes into contact only with the bag, but not with the tank itself.
- a sterile bag can thus be achieved that the RO water in the container 20 always remains sterile.
- the requirements for the sterility of the tank itself can thus be lower.
- the bag may contain a concentrate (solid or liquid). This may be e.g. to act on electrolytes. In principle, the invention also includes the case that there is no concentrate in the container 20, but only RO water.
- the RO water By introducing RO water through the line 40 from the RO plant into the storage container 20, the RO water is mixed with the concentrate therein and in this way the ready-to-use or substantially prepared ready for dialysis solution and transported by the line 40 'to the patient.
- the storage container 20 thus serves in this case not only as a memory for receiving RO water, but also as a mixing device for mixing RO water with concentrate (s).
- the invention also includes the case not shown in the figures, in that downstream of the storage container 20 a mixing device, e.g. In the form of a further container is arranged, in which the mixture of RO water and the one or more concentrates takes place.
- This container may have one or more concentrates or one or more connections for concentrates.
- Reference numeral 30 is a glucose bag or -nado shown, which opens as shown in Figure 1 in the patient line 40 '.
- Vorzugswelse a valve, a pump or the like is provided by means of which / if necessary via the control device patient-specific glucose and / or other concentrates, such as. Electrolyte concentrates can be added.
- the reference numeral 30 thus stands for any container (rigid (e.g., cartridge) or flexible (e.g., bag)) containing one or more concentrates in solid and / or liquid form.
- the dialysis machine 100 further comprises the already mentioned, not shown control device (which may optionally also perform a control), wherein the control device is designed to operate the components of the device.
- the control device is designed so that the RO system is operated continuously, ie even when no dialysis solution is needed. This can be achieved, for example, by having a pump, the water to or through the RO system promotes, is always in operation, ie even if no dialysis solution is needed in itself.
- the pump or other device may be driven so that the flow through the RO system is always constant in time. It is also conceivable, however, to make the control depending on whether dialysis solution is needed or not. In the latter case, the pump etc. can be operated at a lower flow rate than in the former case.
- FIG 2 shows further variants of the arrangement of Konzehtratückschtem, which are indicated in Figure 3 by the reference numerals A and B.
- A may be a glucose concentrate and B may be an electrolyte concentrate or vice versa.
- FIG 2a shows the case that the concentrates enter the storage tank 20
- Figure 2b shows the reverse arrangement in which the contents of the storage container 20 successively flows through the concentrate container A and B.
- the solution preferably ready for use, enters the conduit 40 'which leads to the patient.
- a connector is arranged, which is fluid-tightly connected to a connector of the patient catheter.
- the patient catheter is a section of tubing that is integral with the patient and leads into the peritoneum of the patient.
- the dialysis machine may include one or more pumps, flow rate sensors, other sensors, clamps, valves, etc., which are not shown in the figures.
- the dialysis machine is designed so that the patient only has to connect the patient catheter to the line 40 'and start the dialysis machine.
- Some or more of the functionalities of the dialysis machine may be located in a module or cassette which the user connects to the dialysis machine.
