Definitions
- the invention relates to a connector with a container with a so-called spiking solution for the individual adaptation of dialysis solutions or concentrates.
- the connector ensures contamination-free introduction of the spiking solution into the container of the dialysis solution or of the dialysis concentrate and reliable identification thereof as soon as the original content has been changed by adding a spiking solution.
- the prior art describes the individual adaptation of dialysis solutions.
- DE 32 24 823 one or more additional components are placed in a 1 1 mixing vessel and added prior to treatment in a canister with 9 1 dialysis concentrate.
- the dialysis solution or the dialysis concentrate is assembled in a modular manner.
- WO 99/07419 describes the addition of powdered vitamins and trace elements from commercially available vials to liquid bicarbonate concentrate.
- Problem Solutions for hemodialysis are often prepared from concentrates which are diluted online with ultrapure water from the dialysis machine.
- the concentrates containing the required electrolytes are provided in bags or canisters by nursing staff on the dialysis machine.
- the dialysis machine then has a removal means, e.g. in the form of a suction bar, over which the concentrate is pumped into the machine and there diluted with water, preferably from a central supply unit.
- a basic concentrate containing the buffer bicarbonate and optionally saline containing the buffer bicarbonate and optionally saline
- an acidic concentrate in addition to common salt other electrolytes, such as magnesium, calcium, potassium, glucose and an acid contains.
- the basic concentrate is usually supplied as a dry concentrate and consists only of sodium bicarbonate or sodium bicarbonate mixed with common salt.
- the acidic concentrate is usually a liquid concentrate, which is supplied in plastic canisters with a volume of 3-10 1 canisters.
- the liquid concentrates are composed so that after dilution, an electrolyte solution is obtained, which largely corresponds to the composition of physiological, ie healthy blood plasma.
- the kidneys can be triggered by a variety of diseases. Furthermore, the dialysis treatment itself is a serious intervention in the human organism, which can cause various complications and comorbidities. Therefore, the initial situation at the beginning of treatment may differ from patient to patient. Thus, in some patients very high potassium concentrations are detected before dialysis. In order to make the dialysis gentle, the potassium concentration in the dialysate can be chosen to be slightly higher. The same is possible for the other electrolytes. While most dialysis patients find too much phosphate, some patients who have been dialysed very intensively suffer from hypophosphatemia, which can be alleviated by phosphate in the dialysis solution. Another challenge that dialysis patients often struggle with is malnutrition.
- an improvement can be achieved by adding glucose, vitamins or amino acids to the concentrate. Furthermore, the unintentional removal of trace elements from the blood by the dialysis treatment can be counteracted if necessary by substituting them in the dialysis solution.
- the individual requirements for the exact composition of the dialysis solution used thus show a large spectrum, and the individual adaptation of the dialysis solution to the respective needs of the patient can minimize side effects and improve the treatment success.
- there is the limited storage capacity in the clinic so that only a limited number of different dialysis concentrates can be stored. At the same time, the storage and production of very many different concentrates would require a complex logistics.
- the additional components can be added as highly concentrated solutions, so-called spiking solutions, or as powders to the standard concentrates.
- the altered composition must then be noted by hand by the caregiver on the canister in order for third parties, e.g. the canister is used for multiple treatments, is clearly recognizable. There is a risk here that the note is forgotten, or the label can only be recognized from one side or is easy to overlook. Furthermore, the transfer of liquids from one vessel to another vessel without transfer systems with a risk of contamination or the risk that a portion of the solution is spilled burdened.
- the object of the present invention is to provide a system and method which enables the secure transfer of an additional component, e.g. in the form of a spiking solution, in a standard dialysis concentrate and a secure labeling of the same guaranteed.
- an additional component e.g. in the form of a spiking solution
- this object is achieved by a connector according to the features of claim 1, a combination of the connector with a second container according to claim 11 and a method for producing and labeling a customized solution for dialysis according to claim 12.
- Advantageous embodiments are the basis of the subclaims.
- the invention relates to a connector having a first container for a substance for individually adapting a solution for dialysis.
- the connector has at least one opening which is closed by a closure means.
- the connector is suitable for Put on a second container. After placing on the second container can be made by opening the closure means, a fluid connection between the first and the second container through which the substance for individual adaptation of the solution for dialysis from the first container can get into the second container. After connecting the connector to the second container, at least the connector remains on and identifies the second container.
- the connector and the first container may be integrally formed. Connectors and containers may be configured to be attachable to the opening of the second container. But you can also have a thread with which they can be screwed onto the second container.
- the first container may in this case be e.g. have the shape of a double-walled funnel, which is filled with the substance, and the z. B. is placed on a canister.
- the plastic double wall is open at the bottom and is closed by a closure means, e.g. a welded-on foil, which extends over the entire circular section of the funnel base, closed.
- the sampling means of the dialysis machine is then introduced through an opening in the connector into the second container, the concentrate canister.
- the closure means is detached from the underside of the first container, so that the substance enters the canister.
- the closure means is welded to the underside so that it first separates from the inner ring and thus produces a fluid connection between the first and second container. Then it is also detached from the outer edge, but only partially, so that the closure means remains on the connector and does not fall into the concentrate container.
- the connector is clearly marked by a label indicating the nature of the spiking solution, i. reflects the contents of the first container. At least the connector, in an alternative embodiment also connector together with the first container, remains in use on the second container and thus characterizes the altered composition of the contents of the second container, the concentrate container.
- Connector and first container may consist of two parts.
- the first container with the spiking solution may then be configured to open in an initial state the connector closes, so forms the closure means.
- the connector with the first container is plugged or screwed onto the concentrate container.
- the substance can pass from the first container into the second container and thus adapt the composition to the individual needs of the patient.
- the first container To introduce the removal means of the dialysis machine in the concentrate container, the first container must be removed so that an opening for the introduction of the removal means is formed.
- the connector remains on the concentrate container. In this case, the connector is marked with the contents of the first container. The connector remains over the entire application of the concentrate container and identifies it.
- the connector has two openings.
- a first opening serves as access for the removal means of the dialysis machine to the concentrate container.
- This first opening is largely circular and is centrally located in the connector. The diameter is chosen so that easy access to the concentrate container is possible.
- a second opening may serve to establish fluid communication between the first and second containers. The first container with the spiking solution is then inserted into this second opening.
- the second opening is preferably arranged on the inner edge of the first opening.
- the closure means is preferably formed by a welded-on foil, which closes both openings. It can extend over the entire bottom surface of the connector.
- a first step the connector with the first container is plugged or screwed onto the concentrate container. If the removal means of the dialysis machine is guided through the opening provided for this purpose, the closure means is loosened so that a passage for the removal means is formed and at the same time a fluid connection between the first and the second container. This is ensured by the way the film is welded on. The film is welded weaker at the opening to the first container than at the outer edge of the second opening. Thereby, the welded joint at the first opening is first released and then the welded joint at the outer edge of the second ⁇ ffhung.
- the welded connection at the outer edge of the second ⁇ ffhung is preferably only partially solvable, so that the closure means remains after opening the connection to the connector and does not get into the concentrate container. This avoids contact of the solution for dialysis with the closure means and thus reduces the risk of contamination.
- the connector and the first container can be provided with an outer packaging, which also contributes to a reduction of the risk of contamination.
- the outer packaging can consist of a bag which encloses the connector and the first container.
- the outer packaging can also be designed as a lid, which covers only the lower base of the connector, which comes into contact with the concentrate container in use.
- the substance in the first container for the individual adaptation of a solution for dialysis is present either as a highly concentrated solution (spiking solution) or as a powder.
- Substances that can be used to customize a solution for dialysis are e.g. Electrolytes such as KCl, CaC12, MgC12 etc., vitamins, trace elements, phosphate, iron or glucose.
- the first container preferably has a significantly smaller volume than the second container.
- the volume of the first container may be between 10 and 300 ml.
- the second container contains the solution for dialysis.
- This solution can be a ready-to-use solution for dialysis.
- it is a concentrate which is diluted online from a dialysis machine with water or a solution of other constituents for dialysis. It is particularly preferably the acidic concentrate of bicarbonate dialysis.
- the second container preferably the concentrate container, is preferably a canister or a bag with a volume of 3-12.
- the invention also relates to a combination of a connector with a first container and a second container as described above.
- the first container may be a substance for individual adaptation of a solution contained in the second container for dialysis, preferably a dialysis concentrate.
- the connector enables complete, contamination-free transfer of the contents of the first container into the second container.
- the combination provides an obvious identification of the second container, which helps to prevent errors in the application.
- the invention further relates to a method of making and characterizing a customized solution for dialysis by connecting a first and a second container using a connector as described above.
- opening the closure means at least creates a fluid connection between the first and second container.
- the connector remains on the second container, thereby marking the second container.
- the closure means may be formed by the first container itself, wherein then the production of the fluid connection can be effected by displacement of the first container.
- the closure means may preferably be formed by a welded-on foil which is preferably partially detached from the connector by introduction of the withdrawal means of the dialysis machine, whereby differences in welding strength ensure the opening of the fluid connection between the first and second containers.

- Figure 6 Cross-section through the third embodiment of a connector according to the invention with the first container plugged onto an insert for a concentrate bag and inserted Konzentratansaugstab.
- FIG. 1 shows the cross section through a first connector 1 with a first container 2.
- the connector 1 is screwed onto a canister 3 with acid concentrate.
- the container 2 contains the spiking solution.
- the container 2 consists of a vessel which is inserted into the connector 1 by means of a piston-shaped extension 12.
- the piston-shaped extension 12 has on the head side a closed surface 5, while laterally two cutouts 6 are provided.
- the surface 5 is flush with the lower edge of the opening of the connector 1, the side cut-outs 6 are sealed by the connector 1.
- the container is sealed, there is no fluid communication between container 2 and the canister 3 with the acid concentrate.
- the first container 2 in the connector 1 is displaced downwards so that the part of the piston-shaped extension projects into the canister 3 with the lateral cutouts 6.
- the contents of the container 2 can now enter the acid concentrate without the risk of spilling or contaminating part of the solution.
- this is pulled out of the connector 1.
- the extraction means of the dialysis machine for example, a Konzentratsansaugstab, can be introduced through the central opening of the connector 1 in the canister 3 and concentrate are transferred to the dialysis machine, while the connector 1 remains on the canister 3.
- the connector 1 has a label that describes the contents of the container.
- FIG. 3 shows a second embodiment in which connectors and containers 14 are made in one piece.
- the device has the form of a double-walled funnel, which is inserted into the opening of the canister 3.
- a closure means 5 in the form of a welded-on film is attached, which closes both the central opening of the funnel and the annular opening of the container 14.
- the central opening of the funnel is used as access for the removal means 7 of the dialysis machine with Konzentratsansaugstab 8.
- the container 14 remains there during use of the canister 3.
- the closure means is released from the container 14.
- FIG. 4 shows a third embodiment of the invention, in which connector 1 and container 2 are designed in two parts. In this embodiment, at least the connector 1 remains at the canister opening 4 during use of the canister 3. It is also possible to leave the connector 1 and the container 2 at the canister 3. The label may then be mounted on the connector 1 or the container 2.
- the connector 1 is attached here to the canister opening 4. It has a large central opening 1 1, through which the Konzentratansaugstab 8 is inserted into the canister 3. In addition to this central opening, the connector 1 has a further opening 10. This opening 1 1 forms the canister-side outlet of a fluid line through the connector 1. At the room-side outlet of the fluid line, the container 2 is screwed into the connector 1. Before introduction of the suction rod 8, both openings are closed by the connector means 5 in the form of a welded-on film. When the Konzentratsansaugstab 8 is inserted through the central opening 1 1 in the canister 3, the closure means 5 is released from the connector 1. By different welding strengths, the solution of the film takes place first at the opening 10 of the fluid line to the container 2.
- FIG. 6 shows the device according to FIG. 5 after introduction of the concentrate suction rod 8.
- the present invention ensures the secure transmission of a spiking solution into the concentrate container.
- the change in the composition of the standard concentrate is easily recognized by the retention of the connector on the concentrate container.
