Oxygen concentrators built to be repaired
editorialManufacturing & Supply · nothing open · hardest part: engineering, manufacturing, distribution
Medical oxygen is a basic input that fails at the maintenance layer. Devices arrive as donations, break, and cannot be serviced because parts and documentation are closed.
This is editorial, not a record. Registry entries are cited facts about things that exist; an opportunity is our argument about something that does not. The links to existing work are checked against the catalog — the judgment around them is ours, and you should disagree with it where you know better.
Concentrators are sold as sealed appliances with proprietary service documentation and parts channels. The technology — pressure swing adsorption over a zeolite sieve — is old and well described. The failure mode in practice is not invention but attrition: compressors and sieve beds wear out, service manuals are unavailable, and functioning units are cannibalised for parts.
A design whose serviceable parts are specified and locally sourceable, published service procedures, and an output purity monitor that a technician can trust without sending the unit away. Repairability is the design requirement, not an afterthought — the metric is uptime over years, not unit cost at purchase.
Anyone needing supplemental oxygen where the local hospital has a store of dead concentrators, a pattern documented repeatedly after donation programmes.
Nothing in the registry addresses this. That may mean the gap is real, or that our catalog has a hole — tell us if it is the second.
None cited. Everything above is either reasoning about market structure or a claim you should check yourself. Where we could not source a number, we left it out rather than estimating one.
