Medical Surgical Lighting - Check List
MSL PROVIDES A NEW SOLUTION IN MEDICAL EXAMINATION LIGHTING
Initially a comprehensive product survey was conducted and customer feedback determined that the existing ranges of medical
examination lights needed improvements in:
- Reliability.
- Ease of movement.
- Stability.
- Ease of cleaning to assist infection control.
- Space saving designs.
- Energy saving light sources.
- Ease of installation.
- Maintenance and availability of spare parts.
Listed are some customer problem points that needed to be addressed. Followed by MSL's design and manufacturing improvement responses.
When evaluating, selecting or specifying medical examination lights check for these important MSL key features.
ARM MOVEMENT
Problems:
- Many product brands use spring balanced arms or in some cases gas strut movements.
- Both of these methods can present potential problems and they are not long term low maintenance solutions.
Spring Balanced Arms
- Springs lose tension over time.
- They need to be retensioned and possibly eventually replaced depending on workload.
- They require complex support components, e.g. levers, control arms, pins etc. which all wear and can be subject to failure.
Gas Struts
- Weaken over time and need replacing.
- Leak oil.
- Also require other complex support components to make system workable.
MSL:
A counter-balance arm movement provides the following features:
- Simple in principle.
- Minimal or no maintenance required.
- Effortlessly re-positionable and drift-free after manoeuvring.
- Easy rotation and positioning of the light.
- Robust construction - CNC machined joints with adjustable friction incorporating brass and acetal bushes, also stainless steel axles.
- Provides extended reach for full patient coverage.
INFECTION CONTROL, CLEANING
With the high demands of hygiene it must be possible to wipe down all surfaces.
Problems:
- Spring balanced arms - gas strut arms - exposed cables at moveable joints - friction or knuckle joints - lampheads.
- All have problem areas for cleaning e.g. holes - gaps - recesses - ledges etc.
MSL:
- To assist in infection control, all MSL examination lights have been designed to maximise the use of rounded smooth surfaces.
- All metal construction with powdercoated, anodised and chromeplated finishes for durability and resistance to cleaning agents.
- Series 3 and 1 Models have removable sterilisable handles (autoclavable).
LAMPS
Problems:
- Energy saving lamps are not included.
- Inefficient MR16 halogens widely used.
MSL:
- Supplied with IRC Energy Saving halogen lamps as standard.
LAMPHEADS
Problems:
- Plastic construction which discolours over time.
- Some metal lampheads have high operating surface temperatures and build-up of heat causes early component failures (mainly lampholders and switches).
- Limited range of movement.
MSL:
- Series 3 and 1 Model lampheads offer the following features.
- All metal construction.
- Rotates at both the lamphead and yoke allowing accurate positioning of the light to where it is required.
- Self-cooling air circulation resulting in comfortable operation due to its vented twin wall design.
- High quality electrical components for longer service life, i.e. Teflon-coated high temperature cable - ceramic lampholders - heavy duty 12 volt switches.
- To further minimise heat build up, lampholders are mounted on purpose-made heat sinks and the switches have their own separate enclosures.
- In the event of a component failure in the lamphead the complete head assembly is removable by undoing one screw and disconnecting a make-and-break electrical connector. A replacement head can be operational in minutes, allowing repairs to be carried out in the workshop. This special MSL feature was requested by maintenance staff working in busy hospitals where downtime of equipment is an important issue.
- The three lamphead design gives an overlapping beam pattern minimising shadowing.
- No tools required for lamp replacement and can be performed even if lamp has been in use for an extended period of time, due to the low temperature head design
SAFETY GLASSES
Problems:
- Some lights do not have a safety glass or they have a toughened float glass which has a greenish colour due to its iron content.
MSL:
- Have toughened low iron extra-white safety glasses.
COLOUR CORRECTION FILTERS
Problem:
- Colour correction filters are not readily available.
MSL:
- Available as an ex-stock item, to aid illuminating skin tones, tissue clarity and improving recognition of blood vessels (cyanosis observation).
ELECTRICAL CABLES
Problems:
- Exposed cables give cleaning problems.
- Can have wear points and prone to damage at moveable joints.
MSL:
- Have fully enclosed low voltage cables and there are no wear points at joints.
LOW VOLTAGE TRANSFORMERS
Problems:
- Imported transformers which when replacements are required are not readily available and expensive.
- Many light fittings have remote transformers resulting in higher installation costs due to locating in the ceiling or wall space, this also creates ongoing maintenance issues.
MSL:
- Have TRIDONIC ATCO Australian made transformers, which are readily available and affordable.
- All the MSL examination light range have integral transformers.
- In the case of the ceiling mount models access is not required into the ceiling space after installation.
- This eliminates possible contamination from ceiling spaces and is an essential requirement for "Clean Room" enviromments.
CARDIAC PROTECTED MODELS
Problems:
- Some products do not comply with the specification standard.
MSL:
- All cardiac models comply with the specification standard.
CEILING MOUNTS
Problems:
- Many designs are not available or suitable for different ceiling heights.
MSL:
- Designed and readily available to suit different ceiling heights. (Ceiling heights must be specified at the time of order).
360° CONTINUOUS ROTATING ELECTRICAL CONNECTOR
Problems:
- Not always available as an option. Some brands use slip rings to make the electrical connection.
- The sliding brush contact of a slip ring can lose signal quality over time due to wear.
MSL:
- Has a unique design principle where the electrical conduction path is molecularly bonded to the contacts.
- This creates a connection that is constant and unchanged for the life of the connector.
- Its benefits are:
- Increased reliability.
- No wear, zero resistance.
- Durable, long life (typically lasts millions of revolutions).
- Extremely low electrical noise.
- Less than 1 milliohm resistance.
- Sealed ball bearing construction.
INSTALLATION
Problems:
- Difficult and labour-intensive to install.
MSL:
- Designed and manufactured with a view to assist installation and servicing. This has been confirmed by contractors and end-users.
MAINTENANCE and SPARE PARTS
Problems:
- Difficult to service and repair. Availability and cost of spare parts.
MSL:
- Designed and manufactured in Australia providing all the benefits of locally designed and manufactured products.
I.e. readily available spare parts - affordable price - ongoing product development.
WARRANTY
Problem:
- Having warranties honoured.
MSL:
- Supported by a reputable 5 year limited warranty.
(Component exceptions are lampholders, lamps, transformers and switches these are subject to their manufacturers warranty).
APPROVALS AND TEST CERTIFICATES
Problem:
- Obtaining evidence of the necessary Approvals and Test Certificates.
MSL:
- Current Approvals and Test Certificates. (Copies available on request).
- TGA Certification - Department of Health and Ageing Therapeutic Goods Administration.
- MSL Identifier: 159702 Class 1.
- NATA Certified Light Performance Tests _ MSL Test Report No's:
1763 - 1 - 4 1763 - 9 - 10 1763 - 5 - 8 1763 - 11 - 12.
