An acceptance protocol for clinic buyers and biomedical teams evaluating refurbished patient monitors, current as of September 2026. It gives no alarm-limit or clinical guidance, no repair instructions, and it makes no claim that HHG performs testing.
Patient monitors are the equipment most likely to be bought refurbished and the equipment most likely to arrive with a configuration nobody checked. The reason is structural: a monitor is a platform with options, and the options ¡ª parameter modules, network interfaces, mounting, software level ¡ª determine what it can do. A refurbished unit that looks identical to another may be configured differently, and the difference only becomes visible when someone tries to use it.
What “refurbished” should include
Refurbishment is a commercial description, so the first task at acceptance is to establish what it covered on this unit. A useful seller states what was replaced, what was tested and what was verified afterwards. A seller who describes the unit only as refurbished leaves the buyer to infer the rest, and inference is what acceptance is meant to replace.
| Question | What a good answer establishes |
|---|---|
| What was replaced? | Which parts are new, refurbished or original, and whether batteries and cables were included |
| What was tested? | Whether function and safety testing was performed, by whom, and against what procedure |
| What is the configuration? | Which parameters, options and interfaces the unit actually has |
| What software level? | The version installed and whether it is current for the platform |
Identity, configuration and options
Read the model and serial from the unit, then establish the configuration from the device itself rather than from the listing: which parameter inputs it provides, which modules are fitted, which interfaces are enabled, and how it is mounted. Configuration is the part most often mis-described in refurbished listings, because it is invisible from the front of the unit and because option sets were frequently chosen by the original buyer for a different clinical setting.
Where a purchase depends on a specific capability ¡ª a particular parameter, a network connection, a specific mounting arrangement ¡ª write that capability into the order and verify it at acceptance. “Monitor with options” is not a specification.
Power and battery checks
Battery condition is the highest-value check on a monitor that has been in storage, for the same reason it matters on other portable equipment: it degrades quietly, and it is exercised at the least convenient moment. Establish how the unit behaves on battery, what the manufacturer states about battery service and replacement, and whether the seller can provide evidence that the battery performs as intended.
Where no battery evidence exists, treat the replacement as a cost you will incur and price it before negotiating. Confirm too that a replacement battery is obtainable for this model in your market ¡ª battery availability is one of the practical limits on how long a refurbished platform remains usable.
Sensor and cable verification
Sensors and cables are part of the measurement chain, and a monitor’s displayed values depend on them. For the accessories supplied, check part numbers against the model’s supported accessories, inspect connectors and cable insulation, and confirm that the sensor types match the parameters the clinic uses. Where a purchase includes third-party sensors, verify that the monitor accepts them rather than assuming interchangeability.
- Accessory part numbers recorded and checked against the model’s supported set.
- Connectors inspected for bent pins, damage and contamination.
- Cable insulation and strain relief checked along the length.
- Single-use items checked for lot, expiry and packaging integrity.
Alarm and software validation
Alarm behaviour is a safety function, and it is also a configuration question: whether audible and visual alarms function, and how the unit is set up to report them. Verification belongs with qualified personnel following the manufacturer’s procedure, and the result should be recorded against the unit. Software level matters here too, because alarm behaviour and supported accessories can change between versions.
Where the clinic intends to connect the monitor to a network or a central station, test that path at acceptance rather than during the first clinical day. Network configuration is one of the aspects most often left to be sorted out later, and it is the reason a perfectly functional monitor can sit unused.
Electrical safety and records
The safety test is the document that makes the rest of the acceptance defensible, and its content follows the pattern used across equipment classes: identity tied to the unit, the procedure stated, measured values recorded, test equipment identified with its calibration status, and the date and performer named. Where the test has not been performed, schedule it before the unit enters service and treat the unit as not yet accepted.
Acceptance decision sheet
- Model, serial and configuration recorded and matched to the order.
- Options and interfaces verified against the intended clinical use.
- Battery behaviour established, or replacement costed.
- Accessories verified by part number and inspected.
- Alarm and self-test verification completed by qualified personnel.
- Network or central-station connection tested if it will be used.
- Electrical safety test completed with a usable record.
- Decision recorded with any remediation list and dates.
Questions buyers ask
Is a refurbished monitor safe to use?
That depends on what was done to it and what was verified afterwards. The acceptance process exists because the word refurbished does not describe either.
What is most often missing from a refurbished unit?
Configuration documentation. Sellers describe the model; buyers need the options, interfaces and software level, which is why those checks sit at the start of the sheet rather than the end.
Should we insist on the original manufacturer’s accessories?
Insist on accessories that the model supports and that you can verify. Whether the manufacturer’s own part or a supported equivalent is supplied matters less than being able to confirm that the monitor accepts it and that the measurement chain is intact.
Verify the configuration first, then the power and accessories, then the safety record. If you are evaluating a refurbished monitor and want the documentation that travels with it, ask HHG for the records on a specific unit, or browse the current diagnostic listings.
