Consumables and Reprocessing Questions for a Medical Robot Contract
Which consumable, cleaning and contract questions to settle before signing for a medical robot, and the records to keep afterwards.
Map Every Single-Use Item to Its Instructions for Use
Start the contract conversation with a list, not a price. For one robot, list every item the manufacturer expects to be consumed or replaced: patient-contacting interfaces, drapes, covers, cables, filters, test articles, and any item the instructions for use mark as single-use. Against each line, record the catalogue reference, the quantity the department expects to use per case or per session, the storage conditions, the shelf life and the pack size. This list, not the device brochure, is what the department will actually manage for the life of the contract.
For each line, ask the manufacturer to point to the exact section of the instructions for use that governs it, and keep a copy of the version that applied on the date of the answer. If a representative states that an item can be reused or reprocessed, ask for that statement in writing and compare it with the labelled instructions. Where the two disagree, the labelled instructions for use govern the department's practice.
Note the items the department cannot source independently, and the items whose absence would stop a list. Those two groups deserve the most attention in the contract, because they are the points where the department's continuity depends on a single supplier.
Cleaning, Disinfection and Sterilisation Boundaries
Settle cleaning questions with the people who will do the work: theatre assistants, sterile services and the infection prevention team. Walk through the device and agree, for every surface and every removable part, whether it is cleaned in the room, sent for reprocessing, or must not be wetted at all. Record the answers as a table.
| Item | Question to settle | Where the answer is recorded |
|---|---|---|
| Device covers and drapes | Single-use or reusable, and who removes them after the case | Consumables list and room record |
| Removable patient interfaces | Cleaned on site or returned to the manufacturer | Reprocessing procedure |
| Device surfaces and joints | Which cleaning agents are compatible, according to the instructions for use | Cleaning procedure held by sterile services |
| Transport and storage covers | Whether they are required between uses and where they are stored | Storage section of the room record |
Ask sterile services to confirm in writing that they can perform each step the manufacturer specifies within their existing validated processes and turnaround times. If a step cannot be accommodated, that is a contract issue to resolve before signature, not an operational problem to absorb later. The same applies to the training reprocessing staff will need and to the records they must keep.
Contract Clauses, Records and Change Control
Consumables and reprocessing generate three categories of contract clause worth writing explicitly: how the department is notified when an item changes, what happens to stock and records if the contract ends, and how the department is supported while a cleaning or reprocessing question is unresolved. Ask for the notification route and the notice period in writing, and test the route during the contract's first months so the department knows it works.
Keep records that answer the following:
- which consumable batch or lot was used in each case or session
- which cleaning and reprocessing cycle the device and its parts underwent, and by whom
- what training each person who handles consumables or reprocesses the device has completed
- which version of the manufacturer's instructions for use was current on the date of each activity
- who reviewed the records, when, and what they changed as a result
A record that cannot be tied to a date and a version cannot support a recall or a response to a field safety notice.
Finally, agree how changes are handled. New software, a revised instrument or a different cleaning agent can each invalidate a step the department has already validated on paper. Write a short change-control rule: no change to consumables, reprocessing steps or cleaning agents without a written update from the manufacturer and a review by biomedical engineering, infection prevention and the department that does the work. Keep the review note, even when the outcome is that nothing needs to change.
