SIGMOLUX Disposable Sigmoidoscopes


A self-contained, single use, fully disposable, cable-less and self-illuminating Rigid Sigmoidoscope system designed to optimise mobility during diagnosis and treatment. SIGMOLUX is supplied fully assembled and complete with insufflator for inflating the bowel with a lens to provide a clear view of the observation area.

  • The exclusive ‘LUX’ system ensures the maximum light is transmitted to the end of the SIGMOLUX sigmoidoscope. As well as providing strong, dependable illumination at the end of the product the light pack itself can be disposed of in the medical waste system without the need for disassembly of the product.
  • Within SIGMOLUX a patented mechanism (the ‘CLEAR VIEW’ system) operates to protect the light guide tip during insertion of SIGMOLUX, ensuring that in use all of the available light is delivered from the light guide to the examination site.
  • Compared with traditional products that employ non-integrated light sources the self-contained SIGMOLUX sigmoidoscope enables procedure times to be reduced, while reducing cross infection risk. SIGMOLUX is priced to be competitive with standard products, enabling all users to benefit from the professional feature set.

One of the key criteria for SIGMOLUX was the provision of an effective illumination system, designed to be powerful, dependable and unobtrusive. For SIGMOLUX the light pack, containing batteries and a powerful LED was built into the product handle, using a clear light guide which transports the light close to the end of the product barrel ensuring it is emitted as close to the end of the device as possible. It is this unique light pack and guide that form the elements of the ‘LUX’ system, providing bright and reliable light at the point of interest


Light for the LUX range is generated in a light pack tucked away inside the product handle. Power comes from three alkaline batteries, using a superbright LED as the source.


Light needs to be there when you want it, providing a constant high level of illumination during the procedure, preferably independent of any complexity added by external parts, wires etc. The LUX range uses a simple pull tab to activate the light allowing the user to concentrate on the procedure.

Where it’s needed

The light from the light pack is directed through an optically clear light guide, formed to ensure that the maximum light exiting is directed to the examination area.

Clear unobstructed view

During insertion the SIGMOLUX employs an obturator to both occlude the lumen of the product and enable insertion. This provides a design challenge when using a light guide light source. As well as designing the obturator to ensure smooth transition between the obturator and the product walls and providing a high gloss rounded tip, the obturator design needs to ensure that in use the light guide tip remains free of faecal matter. This is achieved by the patented ‘Clear View’ system, unique to these products. A mechanical cam operates to ensure that during insertion the cam occludes the light guide channel, and on removal lifts to clear the light guide, leaving the tip clean.

Economy without compromise

For many procedures the cost of the products used fades into insignificance when compared to the overhead and variable costs of a clinical environment. Aside from the fixed costs (facility, utilities, depreciation etc) there are the staff and variable costs to consider. While these may not be obvious at a procedure level any ability to reduce them frees funding both within and outside the department.

SIGMOLUX is self-contained, and always ready for use. There is no preparation or set up, once used the entire product is simply thrown away. All products have a high specification feature set, ensuring that the usability of the products meet the same standards as more complex and capital intensive products. With no set-up or clean-up, no need to fund (and find) chargers and power supplies, no need to sleeve cables, disinfect and store items after use, no need for duplicate capital items. SIGMOLUX can significantly reduce both turnaround time and time spent other than with the patient.

SIGMOLUX can minimise your overall procedure costs without the need to compromise on quality, feature set or usability. Contact us for more details.

Fully Disposable

After use the entire product can be thrown away; this reduces procedure turnaround times, and more importantly significantly reduces the cross infection risks. Every use is with a brand new product and SIGMOLUX can be thrown away after use. There is no need for any disassembly of the product, the entire product is disposable, including the integral light pack. While the light pack in SIGMOLUX contains batteries to power the LED, these batteries are alkaline only, so don’t contain any of the heavy metals found in most batteries and can be safely disposed of as contaminated clinical waste.
