Medical Devices: Licences and Safe Buying in India

Why regulation matters to families

Regulation exists to check that a device is safe, performs as claimed and is made and labelled under quality systems. For families, this means: - Accuracy: a monitor that meets standards is more likely to give a reading you can trust. - Safety: electrical safety, fire safety, biocompatible materials, safe alarms and clear warnings. - Traceability: if a problem is found, a batch can be recalled and a manufacturer held to account. - Information: instructions, warnings and contact details in the box. - Redress: a buyer has someone to complain to. Regulation is not a perfect shield. A product can be approved and still be poor for your parent, and an unregulated seller can sell a perfectly decent aid. But the absence of any evidence of regulation, for a device on which a person's health depends, is a reason for caution.

Not every product is a medical device

Different products are treated differently. - Medical devices in the regulatory sense: items intended for diagnosis, monitoring, treatment or support of a medical condition, such as blood pressure monitors, glucometers, oximeters, thermometers, nebulisers, oxygen concentrators, hearing aids, hospital beds, pressure-relieving mattresses and some wheelchairs and walking aids. Which of these need approval or notification, and in what way, depends on how they are classified, and classification has changed over time. - General products: items such as grab bars, bath mats, cushions, night lights, easy-grip cutlery and shower chairs are usually sold as general goods, though they may be subject to general product standards and consumer protection rules. - Wellness and cosmetic items, supplements and "health" gadgets: these fall under other rules and often make claims that regulators do not examine. Be sceptical of devices that claim to treat serious illness; see spotting fake or poor quality care products and supplements and medicine interactions. If you are not sure how an item is classified, ask the seller, and check with the regulator.

What a buyer can ask for

For a device on which health decisions rest, you can reasonably ask the seller or maker for the following. A reputable seller will not be offended. - The manufacturer or importer's name and address, and a contact number. - Evidence that the device is approved, registered or notified as required for its category, in the form the regulator specifies, with the number or reference that allows you to verify it. Ask the seller what applies to this product, and ask them to show it. - The model name and number and the batch or serial number, printed on the device and the box and matching the invoice. - The date of manufacture and expiry or shelf life, for items with consumables such as strips, electrodes or filters. - Instructions for use in a language you can read, with warnings, cleaning and maintenance advice. - Information on accuracy, measurement range and standards that the product meets, for measuring devices; for example, whether a blood pressure monitor has been clinically validated. - Warranty and service terms, and where service is done; see equipment returns warranty and servicing. - An invoice with the seller's details, product details and serial number; see gst and tax benefits on care equipment. If the seller cannot or will not provide such information, consider buying elsewhere.

Reading the label and the box

A genuine product usually carries clear, consistent information: - Name and address of the manufacturer or importer, and, for imported devices, the importer's details. - Model, batch or lot and serial numbers on the device and the packaging. - Manufacturing and expiry dates where relevant. - Intended use and warnings, and symbols for safety information. - Electrical ratings and power details for powered devices. - Regulatory and standards markings appropriate to the product; you do not need to decode them, but you can ask the seller what they mean and how to check them. - Print quality: crisp text, correct spelling, consistent fonts and clean packaging. Smudged print, spelling errors, missing details or peeling labels are warning signs. - Sealed packaging with intact tamper evidence for items that should be sealed, such as strips. Compare the device and the box against the manual and the invoice: models and numbers should match.

Specific cautions for common devices

• Pulse oximeters: accuracy varies between devices, and fingertip readings can be affected by cold, nail polish, movement and skin tone; a device that gives wildly inconsistent readings should be replaced; see pulse oximeter guide and pulse oximeter accuracy limits.
• Blood pressure monitors: choose a model that has been clinically validated, with a cuff that fits; compare it with a clinic reading; see bp monitor buying guide and cuff size and bp accuracy.
• Glucometers and strips: use matching strips, check expiry and storage, and beware of strips sold loose or from unknown sources; see glucometer buying guide and glucose strips and lancets guide.
• Thermometers: a digital model that is clearly labelled and tested against a known reading; see digital thermometer guide.
• Oxygen concentrators and cylinders: buy or rent only through a reputable supplier on a doctor's prescription, with clear documentation, a service plan and backup; never buy a machine you cannot verify; see oxygen concentrator buying guide and breathing support rental costs and checks.
• Nebulisers: a reliable unit with the right mask or mouthpiece; see nebuliser buying guide.
• Hospital beds and mattresses: electrical safety, stable construction, rails that do not trap, and a service plan; see hospital bed at home guide and bed rails guide.
• Hearing aids: ask the audiologist; avoid sound amplifiers sold as hearing aids without testing; see hearing aid buying guide and hearing aid or personal sound amplifier.
• Second-hand devices: the label, history and service record matter; oxygen, mattress and bed motors need servicing and cleaning; see equipment to rent vs buy checklist.

Where and how to buy

• Prefer established pharmacies, medical equipment suppliers and manufacturers' authorised dealers, which can provide an invoice, a warranty and service.
• Online: buy from the maker's own store or reputable sellers; check the listing for the maker's name, model, batch information and return policy; read reviews critically; keep screenshots of the listing, the order and the delivery; open the parcel on receipt and report problems immediately.
• Beware of door-to-door sellers, camps that push expensive devices, unsolicited calls, pressure to pay in cash or immediately, "limited offer" tactics and claims about curing or preventing serious disease.
• Compare prices sensibly: a price far below the market may signal a fake, a seconds product or an old stock; a very high price does not prove quality.
• Ask your doctor or therapist which type of device is suitable, and whether they recommend a model or a validation standard.
• Test on delivery: compare a blood pressure monitor with the clinic's, check an oximeter's consistency, and run the concentrator in front of the technician.

If you are unsure

• Ask the seller to show the evidence of regulatory compliance for that exact model.
• Ask the manufacturer's customer care to confirm the model, the batch and where it is sold.
• Ask the regulator, the Central Drugs Standard Control Organisation or the state drug controller, how to verify a device or report a concern; their processes and online resources change, so check the current ones.
• Ask a clinician, pharmacist or biomedical engineer in a hospital for an opinion.
• Do not use a device you doubt for decisions about medicines or emergencies.

Reporting a problem

If a device behaves unsafely, is counterfeit, is misleadingly labelled or causes harm: 1. Stop using it and keep it with its packaging. 2. Photograph the device, the label, the batch and the packaging. 3. Seek medical help if anyone has been harmed. 4. Tell the seller and the manufacturer in writing. 5. Report it to the regulator and, where relevant, the consumer authority, using the current channels; the Consumer Protection helpline can guide you; see equipment returns warranty and servicing. 6. Keep records and receipts.

Common mistakes

• Buying a measuring device on price alone.
• Trusting a product because it has a medical-looking name.
• Accepting a photocopy of an unclear certificate without asking questions.
• Using an unvalidated monitor to adjust medicines.
• Buying oxygen equipment without a prescription or a service plan.
• Ignoring mismatched batch numbers, spelling errors and damaged seals.
• Not comparing a new device with a clinic reading.

When to ask a professional

Ask the doctor or therapist which devices are suitable. Ask a pharmacist for help checking labels and expiry. Ask the regulator or the Consumer Protection helpline how to verify or report a device. Ask a lawyer for advice if serious harm has occurred. Call 112 in an emergency.
