A practical 6-step checklist for hospitals and clinics receiving new medical equipment—covering spec verification, unboxing evidence, battery and accessory checks, functional testing for PCR and hemodialysis machines, documentation, and the observation period most teams skip.

Elena Varga Elena Varga is a medical imaging systems analyst covering CT scanners, MRI systems, ultrasound platforms, digital radiography, mammography, and ophthalmic imaging equipment. She references IEC 60601-2-44 for CT safety and essential performance while examining CTDIvol, dose-length product, spatial resolution, slice thickness, field uniformity, throughput, uptime, and DICOM interoperability. Her work helps radiology leaders, medical physicists, biomedical engineers, and procurement teams compare image quality, radiation management, workflow integration, serviceability, and lifecycle cost.

Who This Is For

You're on the receiving end of new medical equipment—whether it's five-figure mindray equipment, a fresh PCR machine, a hemodialysis machine, or a patient monitoring setup. This checklist is for you.

I'm a quality and brand compliance manager at a medical company. Every shipment that lands in our clinical ops goes through me before it reaches a ward. Roughly 200+ items a year. We rejected about 12% of first deliveries in 2024—not all defects, but spec mismatches and missing documentation. The most frustrating part of vendor management: the same issues recurring despite clear communication. You'd think written specs would prevent misunderstandings, but interpretation varies wildly.

Six steps below. Follow them in order. Don't skip.

Step 1: Match the PO Before You Touch the Box

Not a suggestion—a rule.

When the pallet hits the loading dock, pull the purchase order and the actual spec sheet. Line them up side by side:

  • Model number exact match (not "similar to")
  • Voltage and electrical spec — confirm it matches your facility
  • Accessory list — matches the quote
  • Warranty start date — in writing

If anything's off, don't open the box. Call the buyer first. Returning an opened unit is ten times messier than returning a sealed one.

Checkpoint: Spec sheet, PO, and unit nameplate all reconcile. No "close enough."

Step 2: Unbox Like You'll Need the Evidence Later

Most teams snap one photo of the crate and move on. Then, three weeks later, they find a dent and can't prove it wasn't them.

Do this instead:

  • Photograph the crate, seals, and labels from multiple angles
  • Take a phone video—actually open the seals on camera
  • Check internal foam and shock indicators for displacement
  • Circle any visible damage on the delivery receipt before signing

Checkpoint: Every angle photographed or filmed with a timestamp.

Honestly—the ten minutes you spend here will save you four weeks of back-and-forth with the vendor.

Step 3: Serial Numbers, Accessories, and the Battery Nobody Checks

This is the step most people skim.

Verify each serial number against the PO and the manufacturer's record. Wrong units get shipped to the wrong site—happens all the time. Then check the accessories before installation begins:

  • Cords and cables — correct spec, not just "a cord"
  • Sensors and probes — check the hours on them, verify the model
  • Battery — this is the one that gets missed

Take a mindray battery. A new OEM battery should hold at least 90% of its rated capacity. If it's been sitting in a system for months, if the packaging has no date, you're getting less. We've seen batteries on new units holding 70%. Run a capacity check. Note it on the acceptance sheet. If it's not on paper, it's "normal wear" three months later.

Checkpoint: Serial numbers, accessory counts, and battery state all logged on the acceptance form.

Step 4: Functional Tests — By Device Type

Don't run the same checklist against every machine. Run the right one:

PCR Machines

Temperatures across the block must be validated per well. More than ±0.5°C variation is grounds to refuse. Run a cycle with an empty block and check the ramp rates against spec. Check the optical path—not after the vendor leaves. That's a common failure point that nobody tests on-site.

Hemodialysis Machines

Flow calibration, conductivity, blood leak sensor alarm, and ultrafiltration accuracy. Run a thirty-minute session. Not five minutes. Intermittent faults that pass a short test will come back and bite you later.

Patient Monitoring and Pressure Mapping

If you're receiving beds, surgical tables, or mattress systems with a "pressure redistribution" claim, ask the rep to demo pressure mapping. What is pressure mapping? It's a sensor array that measures how a patient's weight is distributed across a support surface. Hot spots are where pressure ulcers start. A good pressure map tells you whether that mattress brand's "redistribution" claim is doing anything. A bad one—or none—means you're guessing. It's cheap to do yourself and pays for itself the first time it catches an unexpected hot spot.

Checkpoint: Device-specific test completed and recorded before sign-off.

Step 5: Documentation — If It Isn't Written, It Didn't Happen

Every crate needs:

  • Instructions for use (in your language, not English-only)
  • Calibration certificate with date
  • Electrical safety report (IEC 60601 or equivalent)
  • Warranty terms and service contact
  • Packing list with traceable serial numbers

If any of it is missing, don't sign. "We'll send it later" is a phrase we've heard before, and it doesn't always come true. We had one unit sit unusable for six weeks because the lot traceability paperwork kept getting "lost." Six weeks. That's real money.

Checkpoint: All documents filed and cross-referenced with the purchase order.

Step 6: Observation Period Before You Sign Anything Final

Don't sign off the same day, no matter how much the vendor pushes.

Run the device in its normal workflow for two to three days minimum. Have nursing staff use it. Watch for alarm behavior, alert patterns, and the small annoyances—linen catching on the drawer, interface defaults in the wrong language, data that won't export.

Sign only after that. If the vendor insists on a same-day sign-off, make the observation period part of the acceptance sheet. In writing.

Checkpoint: Observation completed, logged, and attached to the signed acceptance.

Final Notes

A few things that don't get said often enough:

  • Don't accept verbal promises. Yes, it's awkward to ask. Ask anyway.
  • Don't sign one acceptance sheet for five units. Split them. If one fails later, you need to separate it out.
  • Don't sign when the receiver and the installer are the same person. That should always be two different people. Not always possible—but fight for it.

To be fair, this requires more upfront work than most receiving teams are used to. But it beats the alternative—finding out in month three that the unit you thought was spec-perfect is not.

This was accurate as of January 2025. Medical device regulations and vendor terms change fast, so verify current requirements against your internal SOP and the applicable standards before your next round of deliveries.
