Texua 448K

Both pass a 448 kHz current from a handheld electrode through the body to a return plate, and the tissue it crosses warms. In capacitive mode, an insulated electrode forms a capacitor with the skin, and the heating tends to concentrate in more superficial, water-rich tissue. In resistive mode,e a bare metal electrode delivers the current directly, reaching tissue with higher resistance. The 448K sheet does not name either mode, so confirm both from the instructions for use before relying on the photograph.

The photograph shows two handpieces, several interchangeable electrode heads, a large return plate and a clear rack, but the written specification lists none of them. The gap between the 4.5 kg console and the 11 kg gross shipment suggests accessories travel with it, though packaging accounts for some of that weight. Ask for a packing list with the number, size and material of each electrode head, the cable lengths and the conductive medium supplied.

Capacitive and resistive treatment is a hands-on skill. Staff need to learn when to choose each mode, where to place the return plate, how to keep the electrode moving over conductive cream, how to judge dose from the patient's feedback and skin response, and which patients to exclude. Ask the seller what application training is included, then sign off each user as competent under the service's own procedures and refresh that training when staff or protocols change.

Place it on clean, intact skin with full, even contact, following the instructions for use on where it should go, because radiofrequency equipment with a return electrode can concentrate current where contact is poor. Check the skin under the plate after each session. Ask whether the 448K detects poor contact or stops output automatically, since established 448 kHz devices describe contact detection, over-temperature protection and, on some models, a stop switch the patient can press.

Contraindications are missing from the datasheet, so obtain Texua's list with the instructions for use. One established maker of 448 kHz equipment lists pacemakers and other electronic implants, pregnancy and thrombophlebitis as contraindications, and treats anticoagulant medication and reduced skin sensation as reasons for extra care. A 2026 case report documented inappropriate shocks from an implantable cardioverter defibrillator during this kind of therapy, and its authors advised avoiding it in people with those devices. One manufacturer states that metal implants are not a contraindication for its own 448 kHz devices, but that cannot be assumed for this unit.

A 2020 systematic review of 13 studies found that capacitive and resistive therapy tended to reduce pain and disability. However, only two of its nine randomised trials had a low risk of bias. A UK randomised trial reported better pain and function in knee osteoarthritis. At the same time, a 2023 meta-analysis of 68 diathermy studies found most pooled results non-significant, rated the evidence low to very low and did not support routine clinical adoption. NICE's guideline on osteoarthritis tells services not to offer a list of electrotherapies that includes pulsed short-wave therapy, but does not name 448 kHz treatment and centres care on exercise.

Under the Control of Electromagnetic Fields at Work Regulations 2016, employers must assess staff exposure, and European assessment guidance treats diathermy rooms as workplaces that need scrutiny. Measurements around long-wave diathermy units, the family that 448 kHz equipment belongs to, found electric fields able to interfere with electronic implants up to 40 to 45 cm from active applicators. Staff with implants or who are pregnant need specific consideration, and other electronic equipment should be kept clear of the cables and applicators.

Nothing on the sheet clarifies whether 300 W is radiofrequency output, and output from equipment like this depends on the load it drives. Ask for the maximum output into a stated load in each mode and how the 10% to 100% energy scale relates to it. Those two figures let a service write repeatable protocols.

Conductive cream or a similar medium goes on the skin before treatment, and suppliers of 448 kHz devices provide it for that purpose, but the 448K sheet names none. Ask which medium the manufacturer specifies, how to clean the electrode heads and return plate between patients, and how long the heads and cables are expected to last. Warranty terms are included in the seller's quotation. Medigear.uk can also help arrange delivery, installation, commissioning, familiarisation and ongoing service.

For therapeutic use, the 448K would fall under the UK Medical Devices Regulations 2002, where a capacitive-resistive diathermy unit is typically Class IIb, as at least one comparable device is classified as such in Europe. IEC 60601-2-3 covers short-wave therapy from 13 to 45 MHz, so it does not reach 448 kHz; established 448 kHz devices instead cite IEC 60601-2-2, the particular standard for high-frequency surgical equipment, together with IEC/BS EN 60601-1 for basic safety and IEC 60601-1-2 for EMC. Ask which standards Texua applied, and note that the device must appear on the MHRA register through a UK Responsible Person and that the sheet shows no CE marking.

Services that cannot give staff time for hands-on training, or that want equipment to run unattended during a session, will struggle with a technique that needs the clinician's hand throughout. Cosmetic body contouring and home use, both common in marketing for 448 kHz machines, sit outside anything this datasheet describes, and patients with cardiac implants need to be treated elsewhere. If full documentation is needed before any enquiry, Medigear.uk can point the buyer to an alternative specification.
