Article 6 - Storz and Bickel Device Care: The Official Specification and Why It Matters
Share
Storz and Bickel are the only vaporiser manufacturer whose devices hold DIN EN 60601 medical device certification. The Mighty+ Medic and the Volcano Medic 2 are in widespread use across the UK CBPM patient population. They are the reference point for what a certified delivery device looks like in this context.
That certification comes with a maintenance specification. It is in the device manual. Most patients have not read it. Most clinicians have not discussed it. This article sets out what that specification covers and where it stops.
What the manual covers
Storz and Bickel provide cleaning guidance for device components using isopropyl alcohol. The full specification, including method and timing, is in the manual supplied with the device. Patients should follow it as the starting point for maintenance.
Why maintenance matters to the certification
The DIN EN 60601 certification defines the performance standard the device must meet. A device that is not maintained cannot be assumed to be operating to that standard.
Blocked screens alter airflow resistance and thermal dynamics. Contaminated airpaths affect what reaches the patient. Degraded seals break the controlled environment of the heating chamber. A device with extended periods of unaddressed residue buildup is not performing to the specification it was certified to, regardless of what the label says.
Where the manual stops
The manufacturer's guidance covers routine cleaning with IPA. It does not address what happens when residue has built up beyond routine maintenance. It does not cover cross-contamination from third-party accessories, which fall outside the certification entirely.
For a CBPM patient medicating multiple times daily, the gap between the manual and adequate maintenance is meaningful. The treatment pathway assumes the device is functioning as certified. If it isn't, that assumption does not hold.
For a deeper look at what that residue actually is and what it means for what patients inhale, see Article 7 - Grade, Residue, and Risk.
Third-party accessories
Many patients use third-party mouthpieces, whips, cooling units, water pipe adapters, and dosing capsules. These are not part of the certified device. Their use is a departure from the certified configuration and introduces variables the manufacturer's specification does not cover. The cleaning requirements for those accessories, and the risk of cross-contamination with the device, are the patient's responsibility to manage.
Beyond the manual
Where components cannot be fully rinsed, or where residue has built up beyond what IPA cleaning addresses, a pharmaceutical-grade purification solution is the appropriate standard. Over-the-counter IPA leaves its own residue in components that cannot be rinsed. A solution formulated specifically for vaporiser maintenance, without solvent residue, removes that risk.
The Purus Lumina Device Purification Solution is formulated at 99.9% pharmaceutical grade for this purpose. Further detail on the difference between IPA and pharmaceutical-grade purification is covered in Article 3 of this library.
Maintenance frequency should reflect usage. A patient using their device three times daily has a meaningfully different requirement to one using it three times a week. The manual does not address this. The patient and their clinical team should.
The clinical responsibility
The manufacturer has produced a maintenance specification. It is the starting point, not the complete answer. The responsibility for ensuring patients understand, follow, and where necessary exceed that specification sits with the prescribing team, the dispensing pharmacy, and the patient.
Device maintenance is not currently part of the CBPM consultation or dispensing conversation. It should be. The device is the final stage of the delivery chain. Its condition determines what the patient actually receives.
