Exam light focusing sleeve

Description

The Exam Light Focusing Sleeve Green Series IV (Welch Allyn part number 48805, stock number 812859) is a dedicated focusing sleeve accessory designed for use with the Welch Allyn Green Series Exam Light IV. The sleeve mounts onto the head of the Green Series IV lamp to narrow and control the light beam, allowing clinicians to concentrate illumination on a specific area of interest during examinations and minor procedures. By enhancing beam focus, it improves visibility and detail recognition in applications where a tight, high-intensity spot is required, such as OB/GYN, dermatology, minor surgical and specialty exam settings. The accessory is supplied as a single, OEM Welch Allyn component and is compatible only with Green Series IV exam lights and Green Series IV OBGYN Exam Light models.

Bnefits

  • Provides precise control of the Green Series IV exam light beam, enabling a more focused, high-intensity spot for detailed examinations and minor procedures.
  • Designed specifically for the Welch Allyn Green Series IV Exam Light, ensuring proper fit, alignment and optimal optical performance.
  • Easily mountable accessory that can be fitted or removed by the clinician without tools according to the exam requirements.
  • Improves visualisation of small structures and areas of interest by reducing scatter and concentrating light exactly where needed.
  • Supports more efficient and comfortable examinations by minimising the need to reposition the lamp or the patient to achieve adequate focus.
  • OEM Welch Allyn component, manufactured to meet original equipment specifications for fit, function and durability.

Indications

  • Use as an accessory with the Welch Allyn Green Series IV Exam Light or Green Series IV OBGYN Exam Light (model 48810 and related configurations) when a more focused and concentrated light beam is required.
  • Clinical examinations and minor procedures in which detailed visualisation of a small anatomical area is necessary (e.g. OB/GYN, ENT, dermatology, minor surgical and specialty exams).
  • Situations where tightening the beam helps reduce stray light, glare or illumination of surrounding areas, improving contrast and clinician comfort.

Composition

  • Exam light focusing sleeve designed as an OEM accessory for the Welch Allyn Green Series IV exam light head.
  • Manufactured as a rigid focusing component engineered to interface mechanically with the Green Series IV lamp; specific construction materials are not publicly specified in distributor documentation.

Formulation

  • Non-sterile, reusable mechanical accessory – no medicinal or pharmacological components.
  • Optical focusing sleeve engineered to alter and narrow the illumination pattern of the Green Series IV LED exam light.
  • Intended for long-term, multi-patient use with appropriate cleaning and disinfection between patients according to local infection-prevention protocols and the lamp manufacturer’s instructions.

Packaging

  • Supplied as a single (each) Exam Light Focusing Sleeve Green Series IV.
  • Packaged as an OEM Welch Allyn accessory, typically labelled with manufacturer number 48805 and stock/SKU 812859.

Usage

  • Ensure the Green Series IV exam light is switched off and cool before fitting or adjusting the focusing sleeve.
  • Mount the focusing sleeve onto the designated portion of the Green Series IV lamp head according to the lamp’s user manual, ensuring it is fully seated and secure.
  • Switch on the exam light and position the light pipe as usual over the area to be examined.
  • Adjust the focusing sleeve as directed in the lamp instructions (e.g. sliding or rotating, depending on design) to narrow or concentrate the light beam onto the specific area of interest.
  • Verify that the focused beam provides adequate illumination and that the sleeve is stable before beginning the examination or procedure.
  • After use, power down the light and allow components to cool before cleaning the focusing sleeve with an appropriate, manufacturer-compatible disinfectant or cleaning agent, following local infection-control protocols.
  • Do not autoclave or expose the sleeve to high temperatures or harsh chemicals unless explicitly permitted by Welch Allyn’s device-care guidance.
  • Periodically inspect the focusing sleeve for cracks, warping, discoloration or other damage; replace the accessory if its integrity or performance is compromised.

Contraindications

  • Not intended for use with any exam light other than the Welch Allyn Green Series Exam Light IV (including related Green Series IV OBGYN configurations).
  • Do not use if the focusing sleeve is visibly damaged, warped, cracked or does not secure properly to the exam light head.
  • Do not use in sterile fields or environments requiring sterile accessories unless used in conjunction with an approved sterile barrier that does not interfere with lamp performance and is compatible with manufacturer guidance.
  • Use is contraindicated where modification of the beam pattern could obscure the clinician’s field of view relative to established procedural protocols.

Adverse Effects

  • If installed incorrectly or used when damaged, the focusing sleeve may produce an uneven or misaligned beam, potentially reducing visibility during examination.
  • Over-focusing the beam in very sensitive areas may increase glare or visual discomfort for the clinician or patient if lamp intensity is not appropriately adjusted.
  • Inadequate cleaning and disinfection between patients can contribute to cross-contamination or infection risk; proper reprocessing protocols must be followed.

Storage Conditions

  • Store the focusing sleeve in a clean, dry environment at typical room temperatures when not mounted on the exam light.
  • Protect from excessive heat, direct sunlight and corrosive chemicals that may degrade plastics or optical surfaces.
  • Keep away from sharp objects or heavy loads that could scratch, crack or deform the accessory.
  • If removed from the light for storage, place it in a dedicated container or compartment to prevent contamination and mechanical damage.
