Dialysis Systems TRIZ Cases

Integrating the peristaltic pump support surface directly into a sheet metal housing reduces assembly complexity and production costs.

Parallel cation exchange resins manage sodium levels in regenerated dialysate, resolving trade-offs between fluid volume reduction and solution purity concerns.

An ultrafiltration device operates in vent mode to raise liquid levels in the air separator receptacle.

Passive mixing elements induce non-laminar flow patterns in a microfluidic oxygenation device to enhance blood gas exchange.

A determining unit compares estimated and actual treatment sessions to manage undiluted dialysate preparation.

Composite plastic frame with embedded metal stiffening elements provides mechanical rigidity and electromagnetic compatibility for monitor integration.

Acoustic sensors detect intravascular pressure waves through the dialysis needle, comparing ratios to standard values to prevent patient harm from dislodgement.

Sterile-filtered compressed air mixes basic and acidic dialysis concentrates to eliminate manual handling contamination risks.

A circulation apparatus establishes dynamic threshold values for blood flow rate stability to enable precise monitoring of system status.

Rotational flow separates air from blood in an integrated oxygenator, reducing prime volume and hemodilution risks.

Electrical measurement of disinfectant residues ensures patient safety by verifying system tightness and sterility.

A dual alarm system uses a supervisor to monitor controller functionality and activate secondary alerts only when primary signals fail.
