Dialyzer Compressor Integrates Blood Pressure Cuff Air Supply
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current dialysis treatments, particularly peritoneal dialysis, require separate units and additional operations for blood pressure measurement, complicating the process and necessitating extra equipment for compressed air supply.
Innovation Solution
Integration of a compressor system in the dialyzer to supply compressed air not only to conventional pneumatic actuators but also to a blood pressure cuff, with a control unit managing air supply and data processing, eliminating the need for a separate compressor or air pump for the cuff.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a separate compressor or air pump is provided for the blood pressure cuff, then the blood pressure measurement can be performed with dedicated equipment, but the device complexity and number of components increase
Solution Approach 1:
The compressor in the dialysis machine is designed to serve multiple functions: it provides compressed air for pneumatic actuators, valves, and air cushions during dialysis treatment, and also supplies compressed air to the blood pressure cuff for blood pressure measurement. This multi-functional design eliminates the need for a separate dedicated compressor for blood pressure monitoring, thereby reducing device complexity while maintaining measurement reliability
Solution Approach 2:
The patent combines the blood pressure measurement system with the existing dialysis machine by integrating the blood pressure cuff and its compressed air supply into the same device. The compressor, control unit, and pressure sensor are merged into a single integrated system, allowing both dialysis treatment and blood pressure monitoring to be performed with one device rather than requiring separate equipment
2Ease of operation
If all components for blood pressure measurement are integrated into the dialyzer, then ease of operation is improved, but the device complexity increases
Solution Approach 1:
The control unit for blood pressure measurement is integrated into the existing control system of the dialysis machine. The same control unit that manages dialysis treatment parameters also controls the blood pressure cuff inflation, deflation, and data processing. This integration allows the user to operate both functions through a single unified interface, improving ease of operation despite the increased functional complexity
Solution Approach 2:
The control unit is designed to perform multiple functions: it controls pneumatic actuators for dialysis fluid flow, manages the hydraulic pump, and also controls the blood pressure measurement procedure including cuff inflation, data acquisition from the pressure sensor, and display of results. This multi-functional control approach simplifies user interaction by providing a single point of control for all operations
