Definitions

  • the present invention relates to a combined eye and ear protection device.
  • the invention finds utility as an anxiety reduction device for medical and dental procedures, although it may be used in other fields including cconstruction and maintenance, manufacturing, medicine, leisure and fashion, and sport.
  • Attached eye and ear protection devices are known and they find minimal utility in industry where they are used to protect a wearer's ears and eyes from environmental noise and eye hazards such as dangerous fragments.
  • US 7,020,901 discloses an attached eye and ear protection device comprising a single piece of optically clear polycarbonate resin that provides unimpeded peripheral vision.
  • the eye protective portion is functionally cooperative with, and acts as the adjustable head support for an ear protective portion comprising a pair of cup-like earmuffs, which include an attached ear seal to substantially reduce noise/sound levels.
  • US 6,012,812 discloses an attached eye and ear protection device including at least one speaker assembly, allowing a user to receive an audio signal from a remote source via a receiver.
  • the speaker assembly includes a speaker head that can be inserted into a disposable protective ear insert; so that the audio signal is clearly audible to the user and so exterior noise is substantially muffled.
  • Eye protection devices are also employed in dental surgeries where they are used to protect one or both of the dentist's and patient's eyes from cross-infection, such as dental debris, including enamel, filling material and liquid overspray.
  • a combined eye and ear protection device comprising: a visor portion arranged to fit over the face of a user and having respective ends, and a pair of ear pieces, each adjustably mounted to a respective end of the visor, one or more of each ear pieces including an audio speaker.
  • said visor comprises material which is responsive to elevated light levels to become more opaque in the visible spectrum.
  • the ear pieces may have either a supra-aural or circumaural fit.
  • the visor portion may be provided with visual display means, such as one or more LCD screens, to provide visually perceptible information or images to the wearer.
  • the combined eye and ear protection device of the invention finds particular utility in reducing anxiety in both medical and dental patients receiving treatment.
  • Dental anxiety arises in particular in patients with dental phobia. For such patients, even thinking or hearing about going to the dentist can cause marked psychological distress, and the phobia can even interfere with social functioning.
  • the fear of needles is another anxiety which this device will help to alleviate e.g. giving blood, anaesthetics. Also, before surgical procedures and during medical procedures such as colonoscopies this said device will help to reduce anxiety and reduce the amounts of sedation required.
  • the combined eye and ear protection device of the invention also finds particular utility in reducing eye and ear damage within manufacturing, construction, maintenance, sports and DIY industries.
  • the combined eye and ear protection device may also be used in many other applications to provide audio and/or visual information to the wearer while protecting the wearer's eyes and ears.
  • the device can provide audio instruction to the wearer in relation to a wide range of activities and operations, can provide instantaneous translations to the wearer, for example from a tour guide, and can be used as a computer games headset to enhance an interactive computer game experience. It may also find use in military, space exploration, energy and rescue applications.
  • the protection device may be provided with a respiratory face mask portion adapted to cover the nose or mouth and nose of the wearer, said face mask portion incorporating a filter means to protect from inhalation of noxious gases.
  • the face mask may be adapted for communication with an air supply.
  • the face mask may be removably attached to the visor portion of the device.
  • RFID technology may be embedded into the combined eye and ear protection device to help prevent theft of this device and promote good health and safety practise.
  • Passive RFID tags may be fixed to each device with RFID reader technology deployed at the facility entrances and exits. This creates the infrastructure required to determine if a device has been taken from a location by raising an alarm when an embedded RFID tag passes a reader. Furthermore access to such a facility controlled by RFID, could be restricted to users wearing a combined eye and ear protection device to encourage correct health and safety procedure.
  • a GPS tracking device may be provided to allow the location of the device, and the wearer, to be determined.
  • the visor portion is formed from a material, which is transparent in the visible spectrum and opaque to ultra-violet (UV) wavelengths. Protection against UV light protects the eyes from UV light used during the filling curing process. This property of the visor may also protect users from welding flashes as UV radiation is generated from welding arcs therefore eliminating frontal and peripheral glares in the user's eye.
  • UV ultra-violet
  • the frame and/or visor portion incorporates a push/pull ratchet mechanism to facilitate adjustment of the device to fit the head of the wearer.
  • a material with inherent flexibility allows the device to be adjusted without the use of hinges or other jointed devices. This allows the device to be simple in construction and yet accommodate different sizes of user's head.
  • the visor portion is arcuate and is ergonomically shaped to conform closely with the face of a wearer.
  • this facilitates both frontal and peripheral protection of the eye* from cross-infection, such as dental debris, including enamel, filling material and liquid overspray and also allows unrestricted access to the treatment area by the dentist.
  • this facilitates both frontal and peripheral protection of the eyes from glares from welding arcs, and flying debris from various manufacturing or maintenance fabrication techniques.
  • the visor portion comprises a material selected from the group of electro-chromic or photo-chromatic materials, incorporating photo-chromatic capabilities, such that the visor is more opaque in increased light conditions and more transparent in reduced light conditions provides more comfort to a wearer, for example when a dentist's overhead lamp is in use.
  • This property may also reduce glares/flashes in the frontal and periphery of the wearer's eyes caused, for example, from industrial fabrication techniques such as welding.
  • the in-built speakers within each ear piece may deliver audio to a user, in the form of music, information or any other audible sounds, for example to help sooth and improve the user's experience whilst at the dentist or undergoing a medical procedure or to provide instructions, information or entertainment to the wearer.
  • the audio may comprise instructions relevant to a particular activity undertaken by the wearer or other information relevant to the wearer's activity.
  • the ear defenders are provided with removable foam ear cushions. These cushions provide noise suppression from the surrounding environment, and facilitate delivery of sounds from an audio device/player. The cushions also provide increased comfort to a user by cushioning the ears and providing physical protection from the device. The foam cushions may be disposable, improving hygiene, as the cushions may be changed between one user and the next.
  • a wearer using a control, more preferably a remote control, may control the volume level / radio channel (if available) / track position of the incoming audio. This increases comfort by allowing the wearer to select a preferable audio output and volume level.
  • the docking station may provide wireless communication between the dental/medical combined eye and ear protection device and the remote control. It may also have a recharging functionality so that the dental/medical eye and ear device can be recharged when placed into it during periods of non-use.
  • a remote control may be adapted to be mounted to the arm of the dental chair or held in the patient's hand, also during periods of non-use may be stored in the docking station.
