Introduction

Scuba ivers ely on a single auge o calculate he amount f air

they have eft in their oxygen ank. They are required o check

this device very ew minutes o keep rack of the oxygen evel.

Thisdevice oes otgiveanyaudible r physical larm o indicate

the air pressure asdropped o a certain evel,

Theoxycheck evices an additional iece f kit which ttaches o

the air tank viaa standard irhose.Once he air pressure n the

tank eaches certain evel he device ill sense hisand vibrate,

notifyinghe diver hey have a certain mount f oxygen eft n

the ank. Thedevice ill be wornaround he neck f the diver,

2. Product pecification

2.1 Product scopeThe oxycheck evice s a lowoxygenwarning ystem, arning he

userwhen he oxygen evel n the scuba ank has dropped o cetain

level. he devicess an additional iece fgearwhichwillconnect o

an standard cuba ir ankhousing standard irhouse

2,2 Condition f use

2.2.L How wlll the product be used

The Oxycheck evice ill be wornaround he neck. he device s

directly onnected o the scuba ank via a standard cuba air

hose, nce he air pressure n the scuba ank drops o a preset

level he device will physically arn he user via a constant

vibrationo the neck.

2.2,L Where will the product be used

The productwillbe used n aquatic reas primarily nderwater.

Thedevice ill be exposed o different ressures.

4



2,3 Characteristic

2.3,L The Orycheck devise

The main devicewill be injectionmoulded nto wo sections

whichwill hen be screwed ogether. he wallsof the casing

will be considerably hick o be able o handle he pressure

of water beingappliedwhen underwater.

2.3,2 The neck brace

The neck bracewill be made of a stretchable aterial ith a

Velcro ection o adiust sizearound eck.

2.4 The seals

All sealswill be CNCmachinedo obtain n accurate it to ensure

water ight it.

2.5 Ergonomicconslderatlon

2.5,1 Comfoft of wearing orycheck devic€The device ill be wornaround he neck hus t needs o contour

around he neck or maximum omfort lso he widthneeds o be

small o allow he user o rotate nd pivot he neck reelywithout

5



any interference. he neck brace needs o be made of a soft

flexiblematerial.

2.5,2 Ease of adjusting neck brace

The neck brace needs o be adjustable o allow he device o fit

differentneck sizes. he use of Velcro nd stretch material will

allow he device o fit comfortable round ny neck.

2.6 Ease of connection

The devise hould e easily onnected o the scuba ank

2,7 Appearance

The Oxycheck evise needs o be brightly coloured o it can be

visibleunderwater. he njectionmoulded asing will have he name

clearly mbosses nto he casing.

2,8 Performance

The Oxycheck evisewill be used under water and have o deal with

different ressure nder he water as well as different ypes of water

i,e. salt and resh water2.9 The oxycheck devise performance

The devise will be tested under differentDressures o ensure he

device will not buckle under he Dressure xerted o it under

water. The device will also need o be tested o Drove hat its



water tight and the seals will not deteriorate ue to the

environmentt'ssubjected o.

2.10 The sensing device performance

As he oxycheck evise s a critical afety evice, he operation f

the sensing quipment s vital thus it needs o be vigorously

tested nderwateras well as above. he vibration illalsoneed

to be tested with a candidate earing he full diving gear o

identifyf the vibrations strong nough o alert he user. esting

must nsure hat he sensing evice ill nitiate he vibration nce

the airpressure eaches preset ressure.

2.11 Life and reliability

The Oxycheck evice s expected o achieve life onger han 4

years. The reliabilityof the product will be determined y

testing.2.12 Manufacturing

The Oxycheck evice nd componenb hould e designed ith

manufacturing ost, echniques nd standards n mind How

ever cost should not conflictwith safety and performance f



product. oughtn componenb ill need o comply ithBSEN

15333-2 espiratory quipment tandards.

2.13 Safety

Oxycheck so sofety device, and hus mustadhere o DraftBSEN

15333-2Respiratory quipment standards o ensure ll safety

. standards remet.

2.t4 TheOrycheck oslng

The cosing should hove no shorp corners r edges which

could njure he user.

2.15 Orycheck operoflonol omponents

The esting f oll he operotionol quipment willdeiermine

the operotionol ength of the device. Oiher sofefy eoiure5

need o be included o notify he user f low bottery, n the

event of o low boiiery he device will vibrote n o rhythm

.lndicotion f the device being powered up willbe vio on

LEDight.

2,16 Neck broce

The neck broce should noi be oble to slrongle he user. n

lhe eveni of strongulotion he user must be oble to quickly

loosen he broce ond free hem.
