The Visionstar SJD-241 is a battery-powered dental X-ray generator for intraoral radiography at the point of care. The generator runs at 30 kHz, with tube voltage selectable at 60 or 70 kV, tube current selectable across 1.5, 2.0, 2.5 and 3.0 mA, and exposure timing from 0.1 to 2 seconds. Tube focus is specified at order as 0.4 mm or 0.8 mm.

The control face is a 3.5 inch touch panel: one continuous surface, cleaned in a single pass. That matters for a carried unit. A hand-held tube head is picked up, positioned close to a patient's face and set down again for every exposure, which puts it firmly among the surfaces a practice has to decontaminate between patients under the guidance that applies in its nation — HTM 01-05 in England, with equivalent standards in Scotland, Wales and Northern Ireland — and within the infection prevention expectations CQC and its counterparts inspect against.

Two questions belong in the specification conversation rather than after delivery. The first is panel type: the manufacturer's data sheet does not state whether the screen is capacitive or resistive, and that determines how it responds through clinical gloves. Since the unit is only ever operated by gloved hands, this is not a detail to discover at commissioning. The second is agent compatibility — screen coatings differ in how they tolerate alcohol and chlorine-releasing products over repeated use. Ask for both in writing at quotation.

The housing is shaped to sit in the palm, with the flat control face to the rear and a tapered nose forward. At 220 mm deep the emitting end stands away from the hand while the mass stays close to the wrist.

Published distance from skin to cone is 130 mm — raise that with your Radiation Protection Adviser during specification, since UK dental guidance sets minimum focus-to-skin distances that differ above 60 kV, and this unit offers a 70 kV setting. Power comes from a DC 14.8 V 1600 mAh lithium pack, charged from AC 100–240 V with a DC 16.8 V output, rated at 100–300 VA. Medigear.uk can arrange supply, delivery, commissioning, staff familiarisation and service cover for the SJD-241 across the United Kingdom.

Intraoral radiography carries the diagnostic load in UK general dentistry, and the SJD-241 is configured for that daily volume. It supports bitewing caries detection, periapical assessment of pathology, endodontic working-length and obturation verification, alveolar bone-level review, and root morphology assessment ahead of extraction.

Infection prevention deserves its own place in the specification conversation. A hand-held tube head is picked up, brought close to a patient's face and set down again for every exposure, so across a full list it accumulates a great deal of handling. UK practices work to HTM 01-05 in England and to the equivalent standards in Scotland, Wales and Northern Ireland, with infection prevention forming part of what CQC and its counterparts inspect. Equipment that presents one continuous, cleanable control face fits that regime; equipment whose cleaning requirements are unclear creates work for the practice manager.

Shared-unit settings feel this most. Multi-surgery practices, corporate groups and community services move one unit between rooms and operators through the day, and each move is a decontamination point. Writing the unit into the practice policy — including the hand strap, handled at every exposure — closes the gap most often found at inspection.

Domiciliary and outreach work adds a further layer, since decontamination has to happen away from the practice's own facilities. Agree the arrangements with your infection prevention lead and your Radiation Protection Adviser before the first visit.

Clinically, the unit serves general practice, endodontics, periodontal recall, paediatric and special care dentistry and outreach programmes. Guidance from the College of General Dentistry and UKHSA Dental X-ray Protection Services remains the reference point that UK practices work to, alongside HSE enforcement of IRR17.

One continuous face, cleaned in a single pass

A touch panel presents an uninterrupted surface, so the whole control face is wiped in one movement as part of the between-patient routine — which is the routine that has to happen dozens of times across a working day.

Written into the decontamination policy, not around it

A carried tube head belongs explicitly in the practice policy as a shared, frequently handled item. Settling cleaning agents and strap material at purchase means the policy is written once and evidenced at inspection.

The glove question settled before order

Panel type governs how the screen behaves under clinical gloves, and the data sheet does not state it. Medigear.uk can arrange for the manufacturer to confirm whether the panel is capacitive or resistive, and how it performs with nitrile, as part of your quotation.

Suited to shared and multi-room use

Practices moving one unit between surgeries and operators through the day hit a decontamination point at every move. A single cleanable face keeps that step short enough that it actually gets done.

An exposure envelope that spans the view set

Two kilovoltage settings and four milliamp steps let a protocol reach from paediatric anterior views up to molar bitewings on a large adult, with values agreed by your MPE and recorded as local diagnostic reference levels.

Mass at the wrist, beam well forward

A rounded palm-held body with a 220 mm depth keeps the weight close to the wrist while the emitting end stands away from it, supporting a steady hold through the exposure.

Carried by one clinician

At 1.7 kg the unit sits comfortably within single-person handling for a full list or a community round, alongside whatever else has to travel.

UK supply, commissioning and service through one route

Medigear.uk can arrange listing, supply, delivery, installation, commissioning, staff familiarisation, service cover, planned maintenance and quotations for the SJD-241 across the United Kingdom, including requesting the manufacturer's panel type, cleaning agent, focus-to-skin and filtration documentation.

3.5 inch touch panel

A touch-operated screen forms the control face, presenting settings and machine state on one continuous surface.

Continuous cleanable control face

The panel presents an uninterrupted surface for between-patient wipe-down; confirm agent compatibility with the manufacturer before selecting a disinfectant.

Selectable tube voltage at 60 or 70 kV

Two kilovoltage settings support protocols that vary by region, patient build and the greyscale range a view requires.

Selectable tube current across four steps

Tube current is offered at 1.5, 2.0, 2.5 and 3.0 mA, giving a second exposure variable alongside kilovoltage and time.

0.1–2 second exposure timing

A twenty-fold span reaches direct digital sensors at the short end and phosphor storage plate or film technique at the upper limit.

Tube focus at 0.4 mm or 0.8 mm

Focus size is specified at order, one of the figures governing geometric sharpness at the receptor alongside working distance and receptor type.

30 kHz generator

High-frequency drive produces a steady output waveform through the exposure, supporting repeatable receptor density from one radiograph to the next.

130 mm published skin-to-cone distance

The manufacturer publishes a skin-to-cone figure; confirm with the manufacturer whether this is the focus-to-skin distance and which kilovoltage settings the supplied cone supports, and have your RPA review it.

Palm-held rounded housing

The body is shaped to sit in the palm, with the flat control face to the rear and a tapered nose forward of the hand.

220 mm housing depth

Published depth places the emitting end well forward of the operator's hand while the mass stays close to the wrist.

Ready and exposure indicators

Illuminated status markers signal machine state through the exposure cycle, giving visual confirmation at each stage.

Side-mounted exposure release

The exposure control sits on the side of the housing, within reach of the carrying hand while the head is held in position.

DC 14.8 V 1600 mAh lithium battery

An integrated lithium pack powers the unit away from a fixed power position, charged from AC 100–240 V with a DC 16.8 V output and a 100–300 VA rating.

Moulded hand strap

An integrated strap supports single-hand carrying; confirm the strap material and spare availability, and include it in the between-patient wipe.

FAQ

Frequently Asked Questions

Everything buyers need to know about sourcing medical equipment through MediGear.

Treat it as a non-critical item that contacts intact skin and the immediate patient environment, cleaned and disinfected between patients like any other shared surface in the surgery. Because a hand-held tube head is picked up, brought close to the face and put down for every exposure, it sees more handling across a session than most fixed equipment. Write it explicitly into your decontamination policy under HTM 01-05 or the equivalent standard in your nation, rather than leaving it to be covered by a general instruction.

Ask the manufacturer before ordering — the data sheet does not say. Capacitive panels sense the electrical properties of a finger and respond variably through gloves, with thin nitrile usually registering and thicker or doubled gloves often not. Resistive panels respond to pressure and work through any glove. Since gloved operation is the only operation this unit will ever see, get the panel type confirmed in writing and, where possible, trial it with the glove stock your practice actually buys. Medigear.uk can arrange for that detail to be requested from the manufacturer.

Single-use barrier protection over frequently handled equipment is common UK practice, but it does not replace cleaning — barriers are changed each time, and the surface beneath is still cleaned at the end of the session or whenever a barrier is breached. Confirm with the manufacturer that a film over the panel does not interfere with touch response, and that barrier material does not obstruct the beam path.

Follow the manufacturer's stated compatibility rather than assuming. Screen coatings vary in how they tolerate alcohol and chlorine-releasing agents across hundreds of wipes, and degradation shows up as clouding or reduced touch sensitivity months into service. Ask for the agent list at quotation and cross-check it against what your practice already stocks.

Include it in the between-patient wipe — it is handled at every exposure and easy to overlook. Confirm the strap material with the manufacturer, since a moulded or coated strap wipes down effectively while a woven fabric one does not, and ask whether a replacement is available as a spare.

Raise this before order. UK dental guidance sets minimum focus-to-skin distances for intraoral equipment, and the required figure steps up for sets operating above 60 kV — commonly expressed as 100 mm at 60 kV and below, and 200 mm above 60 kV. This unit offers a 70 kV setting and publishes a 130 mm skin-to-cone figure. Ask the manufacturer to confirm whether that is the focus-to-skin distance or a cone measurement, whether a longer cone is available, and which kilovoltage settings the supplied cone supports. Have your Radiation Protection Adviser resolve it before the unit goes into service.

The pack is a DC 14.8 V 1600 mAh lithium unit, charged from AC 100–240 V with a DC 16.8 V output, so it runs on UK mains directly. The manufacturer does not publish an exposures-per-charge figure, and a backlit touch panel carries its own standby draw, so ask for the figure directly. Request it at quotation along with spare pack availability and pricing.

The Ionising Radiations Regulations 2017 require employers carrying out dental X-ray work to register with the Health and Safety Executive, appoint a Radiation Protection Adviser, nominate a Radiation Protection Supervisor and complete a radiation risk assessment. The Ionising Radiation (Medical Exposure) Regulations 2017 add the appointment of a Medical Physics Expert, justification and optimisation of each exposure, and documented training for referrers, practitioners and operators. A critical examination is required when the equipment is put into service. These duties sit with the employer.

Dental X-ray equipment is subject to routine quality assurance and periodic radiological testing under IRR17, alongside annual electro-mechanical inspection, with a critical examination required at installation. UK service providers commonly apply an annual radiological testing interval to hand-carried units, and your Radiation Protection Adviser sets the schedule. Warranty terms are set and issued by the seller or manufacturer, typically 12–24 months, with battery packs often warranted on a shorter cycle and screen assemblies sometimes covered separately — confirm at quotation.
