Remote Dialysis Unit Wireless Therapy Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current home dialysis solutions require frequent clinic visits due to limited smart card storage capacity and the need for manual caregiver intervention to adjust treatments, limiting patient flexibility and comfort.
Innovation Solution
A medical system with a dialysis unit that can modify therapy parameters in real-time based on control data received from a remote host via a gateway unit, allowing for wireless communication and remote monitoring, reducing the need for frequent caregiver intervention and enabling flexible treatment locations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If smart card storage is used to store therapy and treatment history data, then patient data can be stored and accessed at home, but the storage capacity is limited requiring frequent clinic visits
Solution Approach 1:
A wireless communication module serves as an intermediary between the portable dialysis device and external systems (clinic computers or cloud servers). This module enables automatic transmission of treatment data and reception of therapy updates without requiring physical smart card exchanges or patient travel to the clinic, thereby expanding effective storage capacity and eliminating frequent visits.
2Adaptability or versatility
If manual caregiver intervention is required to adjust dialysis therapy, then treatment can be personalized to patient needs, but patient flexibility and comfort are reduced
Solution Approach 1:
The system continuously monitors treatment data and patient status, automatically adjusting dialysis parameters based on pre-programmed protocols and real-time feedback. This closed-loop control enables therapy personalization without requiring manual caregiver intervention during treatment, allowing patients to receive customized care while maintaining flexibility and comfort at home.
3Extent of automation
If online connection between central location and home dialysis site is established, then data exchange and therapy updates can occur remotely, but system complexity increases
Solution Approach 1:
The wireless communication module performs multiple functions: transmitting treatment data to external systems, receiving therapy update commands, and enabling remote monitoring. By consolidating these diverse communication tasks into a single multi-functional module, the system achieves remote automation capabilities without proportionally increasing overall system complexity.

AI summary
The invention relates to remote controlled blood cleaning of a patient (P). A dialysis unit (110) treats the patient's (P) blood in accordance with a prescribed therapy. The dialysis unit (110) has a bi-directional wireless interface (110W-120W) towards a gateway unit (120), which is further connected (125) to a remote host (140) via at least one interconnecting network (130). Thus, therapy related parameters (Dbp, Dr, dh, Dw) can be transmitted from the dialysis unit (110) to the remote host (140). It is also rendered possible for the remote host (140) to transmit control data (Dctrl) to the dialysis unit (110), the control data (Dctrl) influencing the prescribed therapy being, or to be, executed by the dialysis unit (1 10).
