Personal medical-device research

Understand every part of the air path.

An early exploration of a repairable positive-airway-pressure machine, with accessible firmware, therapy logs and cleanable air-contact parts.

How it works

Follow the system.
One part at a time.

Select a part to see its role, the decisions behind it, and what still needs evidence.

01 / Personal medical-device research

Move air

Choose a quiet blower and define its control envelope.

Fixed pressure, automatic pressure and bilevel control are separate design choices. Their sensing, response and fault handling have not been selected.

02 / Personal medical-device research

Measure pressure

Study pressure, flow and leakage together.

Measurement and leak estimation would inform control and logging. This preview does not provide settings or treatment recommendations.

03 / Personal medical-device research

Condition the path

Explore cleanable humidification and air-contact materials.

Glass, metal and silicone are material candidates. Cleanability, condensation, compatibility and validated processing remain questions for the actual assembly.

04 / Personal medical-device research

Keep the record

Make firmware behavior and logs inspectable.

Open data and fault records are goals. Any future controller needs independently defined power-failure behavior and protective interlocks.

Design principles

What guides the work.

01

Repairability

Prefer components whose purpose, wear and replacement can be understood.

02

Separate cleaning from therapy

A proposed cleaning chamber is its own research problem; its methods are not validated for a breathing path.

03

Accessible data

Explore compatible, documented logs without claiming medical interpretation.

Project status

Know where
the work stands.

Seed-stage personal research. No device, pressure-control system or cleaning process is designed, built or validated. A prescribed, cleared machine remains the therapy reference.
