The SOS HYPERLITE Emergency Evacuation
Hyperbaric Stretcher and Treatment System

Ancillary Equipment

All Hyperlite hyperbaric stretchers are supplied as fully operational units (with the exception of gas supplies).  Being of modular construction, optional extras may be purchased from new or added subsequently (modifications may be required to existing equipment). Other items can be developed to customer requirements.

 LLOYDS REGISTER & ASME SYSTEM CERTIFICATION:  When the Purchaser or his/her Agent does not attend the final testing of each unit prior to delivery, it is strongly recommended that an Independent Third Party Certifying Authority be contracted to witness these tests.   This is a requirement for units built to the Lloyd’s Register Rules.

MEDICAL LOCK: The medical lock permits the transfer of food, drink, medications and other items for the comfort of the casualty, in or out of the stretcher, through a two-door arrangement in the head end dome of the stretcher.  Whilst the stretcher is in operation, one of the two doors will always be in position to maintain the stretcher pressure.  The other door may be removed for access to the lock.  There are bleed screws on both sides of the lock, so that pressures may be equalised between the lock and either the stretcher or the environment.  The internal dimensions are 12.5 cm. (5") dia. x 14 cm. (5 1/2") long and the volume of the lock is 1720 ml. (105 cu. in.) 

INTERNAL FOLDING MATTRESS: For patient comfort a folding mattress, may be supplied, which is also used to pull the patient/casualty into the unit.  It offers more padding than the bare tube and is made from fire retardant materials.   

ADDITIONAL PNEUMATIC AND/OR ELECTRICAL CONNECTIONS: Customers may require additional pneumatic and/or electrical connections at the penetrator plate for intensive patient monitoring and critical care.  E.g.: ECG, BP, IV, O2 Pulsometer, and Ventilator.

INTERNAL ANALOG BACK-UP PRESSURE GAUGES IN STRETCHER: Whilst the standard pressure gauge in the control box will always display the differential pressure between the stretcher and the ambient pressure, the readings will change when ambient pressure changes,(in an aircraft or a submarine).  The gauge, mounted inside the stretcher, will indicate the true stretcher pressure (in MSW or FSW) above 1 ATA. 

EXHALED GASES HOSE ASSEMBLY (Externally mounted): In restricted areas, the exhaled breathing gases, which contain high concentrations of oxygen, may cause a fire hazard.  With the use of this hose, the exhaust gases can be piped to a suitable exhaust location.       

THERMOMETER or THERMOMETER/HYGROMETER: These compact LCD electronic digital units indicate either temperature (in °F or °C) or temperature & relative humidity inside the stretcher, viewed through the window.         

AIR AND/OR OXYGEN ADAPTERS: In view of the different supply valves fitted to air and oxygen cylinders etc. around the world, the supply regulators may require adapters. 

OXYGEN MONITOR or OXYGEN/CARBON DIOXIDE MONITOR: These units can be supplied either separately or as a combined unit in order to monitor either the stretcher/stretcher environmental gases or the patients exhaled gases. The oxygen monitors display the partial pressure of oxygen on a digital LCD display in millibars relative to the ambient pressure. The carbon dioxide monitors usually display the percentage CO2 in either the exhaled gases or the stretcher/stretcher environment.

LIFTING SLINGS: A lifting sling, complete with a central ring and four lockable cleats, is available for winching the Hyperlite complete with accessories.   A lifting sling is also available for lifting a stretcher with its axis vertical, for vertical entry locks (submarines) or steep stairwells.  Lifting slings are supplied with test certs. SWL - 300 Kg (660 lb). 

SUPPLY GAS PACKAGE     This package comprises three 18* litre 207 bar (3000psi) oxygen cylinders and two 18* litre 232 bar (3360 psi) air cylinders, all with boot and two backpacks.  This should be sufficient to complete a normal US Navy Table 6.  Cylinder valves for air are normally DIN or International, and for oxygen are Bullnose, DIN, Pin Index or CGA.  [* Subject to availability, otherwise 15 litre]
