Benefits of technology

The invention is about a connector and two containers for use in dialysis treatment. The connector is designed to allow for easy transfer of substances between the two containers without contamination. The connector has two openings, one for accessing the concentrate container and one for inserting the tapping means of the dialysis machine. The connector remains on the concentrate container and identifies it during use. The combination of the connector and containers provides an obvious identification of the second container to prevent mistakes in use. The invention reduces the risk of contamination and allows for individual adjustment of the dialysis solution according to the needs of the patient.

Problems solved by technology

Dialysis treatment itself still constitutes a serious intervention into the human body and may cause various complications and comorbidities.
Malnutrition is another challenge often confronting dialysis patients.
On the other hand, there is limited storage capacity in the clinic, so that only a limited number of different dialysis concentrates can be kept on hand.
There is the risk here that the notation may be forgotten and / or that the inscription is discernible from only one side or is also easy to overlook.
In addition, transferring liquids from one vessel to another vessel without any transfer systems is burdened with a risk of contamination or the risk that some of the solution may be spilled.

second embodiment

[0036]FIG. 3 shows a second embodiment in which the connector and the container 14 are embodied in one piece. In the embodiment shown here, the device is in the form of a double-walled funnel, which is inserted into the opening in the canister 3. A closure means 5 in the form of a welded film is applied to the underside of the funnel, closing both the central opening in the funnel and the ring-shaped opening in the container 14. The central opening in the funnel is used as access for the tapping means 7 of the dialysis machine with the concentrate suction rod 8. The container 14 remains on the canister 3 during use of the latter. If the concentrate suction rod is inserted into the canister through the central opening, the closure means is released from the container 14. Due to the difference in weld strengths, the film is released first at the inner ring of the outlet of the double-walled funnel. Then the film is partially released on the outer ring. The film is welded to the outer ...

third embodiment

[0037]FIG. 4 shows the invention in which the connector 1 and container 2 are embodied in two parts. In this embodiment at the least the connector 1 remains on the canister opening 4 during the use of the canister 3. It is likewise possible to leave the connector 1 and container 2 on the canister 3. The inscription can then be applied to the connector 1 or to the container 2.

[0038]The connector 1 is attached here to the canister opening 4. It has a large central opening 11 through which the concentrate intake rod 8 is introduced into the canister 3. In addition to this central opening, the connector 1 has an additional opening 10. This opening 10 forms the outlet of a fluid line through the connector 1 on the canister end. At the outlet of the fluid line on the room end, the container 2 is screwed into the connector 1. Before inserting the intake rod 8, the two openings are both sealed by the connector means 5 in the form of a welded film.

[0039]If the concentrate intake rod 8 is int...

Abstract

The invention relates to a connector for a container with a spiking solution for individual adjustment of dialysis solutions and / or dialysis concentrates. The connector ensures a contamination-free introduction of the spiking solution into the container of the dialysis solution and / or of the dialysis concentrate and reliable labeling of same as soon as the original contents have been altered by adding a spiking solution.

Description

[0001]The invention relates to a connector with a container with a so-called spiking solution for individually adjusting dialysis solutions and / or concentrates. The connector ensures a contamination-free introduction of the spiking solution into the container of the dialysis solution and / or of the dialysis concentrate and reliable identification of same as soon as the original contents have been altered by the addition of a spiking solution.STATE OF THE ART[0002]The individual adjustment of dialysis solutions is described in the state of the art.[0003]In DE 32 24 823 one or more additive components is placed in a 1-liter mixing vessel and added to a canister with 9 liters of dialysis concentrate before the treatment. The dialysis solution and / or the dialysis concentrate is / are assembled in a modular fashion.[0004]WO 99 / 07419 describes the addition of powdered vitamins and trace elements from commercial vials to liquid bicarbonate concentrate.STATEMENT OF PROBLEM[0005]Solutions for h...
