Three figures govern siting. 45 feet for operators who are pregnant, measured from the applicator, when the unit is activated. 45 feet for anyone wearing a cardiac pacemaker, measured from an operating unit. 36 feet minimum from other medical devices. All unnecessary persons are also kept out of the treatment location while the unit runs. Those distances usually decide which room the unit can go in, so check them against a floor plan, including the rooms next door and upstairs, before you order.

No. The clinician remains with the patient throughout shortwave diathermy therapy. The pivoting electrode arm carries the applicator so that nobody has to hold it, which is a separate point: an electrode must never be held in the hands during therapy. Plan the appointment around a clinician in the room for the full 1 to 30 minutes, because the time does not come back as an admin slot.

Over 90 clinical protocols on board, plus 200 user-defined storage slots. Both sit behind a colour LCD touchscreen, so a protocol is recalled at the screen and the parameters come up with it. The unit runs two output channels with automatic resonance tuning, which keeps the set power matched to the applicator as the load changes through a treatment. Output is set in 5 W steps across 0 to 100 W continuous and 0 to 200 W pulsed at 50 ohm.

Chattanooga's contraindication list is long, and the categories are: implanted electronic devices including pacemakers, defibrillators, bladder, spinal cord, deep brain and other nerve stimulators, cochlear implants, bone growth stimulators, myoelectric prosthesis electrodes and any implanted metallic lead; metal, internal or external, including implants, sites where implants were removed, braces, fillings, staples, fixators, joint replacements, metal IUDs and shrapnel; haemorrhage or risk of it, severe arterial obstruction, deep vein thrombosis, phlebitis, varices and occlusive vascular disease; altered temperature sense in either direction; septic conditions, empyemas, osteomyelitis, tuberculosis and acute inflammations; malignant and undiagnosed tumours; pregnancy, the menstrual cycle, the pregnant or potentially pregnant uterus and reproductive organs; and application over the eyes, the carotid sinuses, the stellate ganglion, the vagus nerve, open lamina and the epiphyses of growing bones. Read the full list in the instructions for use before you plan a caseload around this device.

The warning is explicit: do not administer shortwave diathermy to a patient who has had an implant in the past unless you are absolutely certain that the implant and all leads in their entirety have been removed. Patients with implanted electronic devices must not be treated even if the implanted device has been turned off, and a lead left in place counts as an implant for this purpose.

0 to 100 W continuous at 50 ohm and 0 to 200 W pulsed at 50 ohm, in 5 W steps. Pulse frequency 10 to 800 Hz in 10 Hz increments; pulse width 20 to 400 microseconds in 20 microsecond increments. Operating frequency 27.12 MHz +/- 0.6%. With the 80 mm capacitive electrode, continuous output derates to 0 to 80 W at 50 ohm. Two output channels tune automatically to resonance, so the power you set at the screen stays matched to the applicator through the treatment.

1 to 30 minutes, set in 1 minute increments. Treatment time is set on the touchscreen in whole minutes, so an appointment is built around a maximum of half an hour under the field. With the clinician staying in the room for the whole treatment, the duration is the number that sets how many patients the unit can carry in a day.

Check the packaging against the unit, applicator, power cord, User Manual, Quick Start Guide and indicator discharge tube. The kit is elsewhere described as taking in the inductive drum, connection cable, arm, indicator tube and CD manual, so the electrode arm is the item to look for before you order a second one. Ask us to confirm the carton contents before you add a second arm to the order.

They are used in pairs, one either side of the treatment area, and each size requires two units. The three sizes are 80 mm, 120 mm and 165 mm, and each size is a matched pair, never a single plate. Ordering one of a size leaves you with half a treatment set, and the 80 mm pair also derates continuous output to 0 to 80 W at 50 ohm.

Not closely. Beyond the 36 foot separation, two other machines in the Chattanooga range carry their own clearances. Patients with an implanted neurostimulation device must not be treated with, or be in close proximity to, any shortwave diathermy, because energy from diathermy can result in severe injury or death. An Intelect Focus Shockwave must be installed no closer than 1 m to electromagnetic interference sources such as electrosurgery or diathermy. If you run several modalities, plan the layout around the SWD100 first.

120 V~, 50/60 Hz, 500 VA, on a 110 V circuit with a 15 A breaker. The platform accepts 100 to 240 VAC, so size the circuit from the US figure and give the unit a breaker of its own where the room allows it. Electrical safety class B, tested to IEC, EN and UL 60601-1 and IEC 60601-2-3.

60 lb (27.22 kg). The cabinet measures 16.5 x 16.14 x 45 in., and a tight room should be planned to 24 x 12 x 45.5 in. so the base and the electrode arm both clear. It stands on its own base and does not mount to a modality cart, so the floor space is permanent rather than shared with another modality.

The equipment is to be used by, and sold to, a trained clinician, and that clinician remains with the patient throughout therapy and keeps unnecessary persons out of the treatment location. An electrode is never held by hand while the unit is running. Bystanders stay 45 ft clear, which includes anyone with a pacemaker and anyone who is pregnant, and the cabinet sits 36 ft from other devices. Treatment time is set on the touchscreen in 1 minute steps to a maximum of 30 minutes, so one person is committed to the room for that whole window.

The SWD100 has left Chattanooga's current US range, and the shortwave unit in the current catalogue is an international-market model. The warranty term on the SWD100 is two years, and the unit itself is unchanged: 27.12 MHz at 0 to 100 W continuous and 0 to 200 W pulsed, on the same 60 lb floor-standing base. Before you commit to a floor-standing device, settle platform status, service availability and the current warranty position in writing.
