Texua 7801+2

Everything a clinician needs to dose it. Ask for the operating frequency; the intensity range in watts per square centimetre; whether the output is continuous or pulsed, and at what ratio; the effective radiating area of the head; the beam non-uniformity ratio; the head diameter; and the timer range. Ask also which standard the head was tested against and for its calibration certificate. Without those, the second applicator cannot appear in a written protocol.

Because heads drift, and the drift is invisible. BS EN 60601-2-5, the particular standard for ultrasonic physiotherapy equipment, works to a 20% tolerance on displayed output, and IEC 61689 sets out how the field is measured between 0.5 and 5 MHz. Published surveys have found roughly two-thirds of physiotherapy units failing minimum calibration in earlier Scottish and Canadian studies, and 44% of one 45-machine sample failing either calibration or electrical safety. IEC/TS 62462 exists as a maintenance test guide, so build an annual output check into the service contract.

Radial transmitters differ in face shape, diameter and mass, which changes how the pulse spreads and how deep it feels, so a set of nine covers different regions and tolerances. The datasheet names a count and no detail. Ask which transmitter matches which application, what each is made of, how they are cleaned between patients and how often they are replaced, since transmitter faces wear with use.

The sum is the total over the rate. A 500-impulse warm-up at 8 Hz lasts about a minute, 2,000 impulses at 15 Hz take roughly 2 minutes 13 seconds, and the 9,900 maximum at 12 Hz would run for about 13 minutes 45 seconds. Those sums shape the appointment far more than the bar setting does. Confirm that output halts by itself at the preset total.

Nothing states whether the two can run at once; in any case, a single operator would run them one after the other. The practical question is sequencing: which treatment comes first, whether both are appropriate for the same presentation on the same day, and how the record shows the settings for each. Agree on the order in the protocol rather than leaving it to whoever is on the list.

Both applicators need their own screening. NHS shockwave information commonly excludes pregnancy, blood thinners and antiplatelet drugs, steroid injection into the area within recent weeks, and any infection, wound or cancer at or near the treatment site. A UK manufacturer's instructions for a therapy ultrasound unit list tumours, infection, the pregnant uterus, sites irradiated within six months, thrombosis and impaired circulation, reduced sensation, bleeding disorders, implanted devices including pacemakers, and particular care near the eye, with metal implants treated as a reason for low doses. Texua's own list must still come with the instructions for use.

They are not equally supported. NICE has reviewed shockwave for four conditions: plantar fasciitis, refractory tennis elbow, tendinopathy of the Achilles and stubborn greater trochanteric pain, each under special arrangements, while calcific shoulder treatment stays within research. For therapeutic ultrasound, a 2020 review concluded it helps some soft-tissue conditions but that conflicting results prevent any positive recommendation; a 2024 pooling reported no significant effect at the shoulder; and a meta-analysis comparing the two modalities over the longer term found both effective, with shockwave clearly ahead.

Radial treatment is loud: one study measured around 88 dB during sessions, and employers must act on the risk once daily exposure is likely to reach 80 dB(A), as the Control of Noise at Work Regulations 2005 require. The grille in the photograph points to a compressor, so ask whether it has an air reservoir and, if so, at what pressure and volume. A system under 250 bar litres needs no written scheme under the Pressure Systems Safety Regulations 2000; safe limits and upkeep still apply.

Coupling gel for both applicators, since neither works dry, and cleaning material for the probe faces. The projectile inside a radial handpiece wears down, with lifetimes quoted in millions of impulses on comparable listings. At the same time, an ultrasound transducer becomes a wear item once output drifts. Ask what the handpiece service interval is, what a replacement head is quoted at, what the lead time is, and whether loan equipment covers a repair.

Treatment use places the 7801+2 under the UK Medical Devices Regulations 2002, typically Class IIa or above depending on the stated use, which the declaration of conformity confirms. Two particular standards are in play: BS EN 60601-2-5 for the ultrasonic side, written for unfocused circular transducers, and IEC 60601-2-36 for pressure-pulse equipment, which was drafted around lithotripsy rather than radial handpieces. IEC/BS EN 60601-1 and IEC 60601-1-2 apply throughout. MHRA registration runs through a UK Responsible Person, and the sheet carries no CE marking.

Services that will not chase the missing ultrasound figures, since an undocumented applicator is one nobody can dose or audit, and services with no arrangement for annual output testing. Shared rooms where shockwave noise carries are a poor match too, as are calcific shoulder work outside research, cosmetic use and home use, none of which the sheet supports. Where a buyer needs both modalities documented before ordering, Medigear.uk can point the buyer to an alternative specification.
