Our goal is to work-related injuries. Our goal is to develop develop an ergonomic design to minimize the an ergonomic design to minimize the forces appliedforces applied and improve the current and improve the current ultrasound procedure.ultrasound procedure.Background InformationBackground InformationCurrent Ultrasound Current Ultrasound ProceduresProcedures–Console andConsole and TransducerTransducer–ProceduresProceduresEchocardiogramEchocardiogramBiopsyBiopsyBackground InformationBackground InformationMusculoskeletal Musculoskeletal disordersdisorders–Occur in 80% of sonographersOccur in 80% of sonographersCarpal TunnelCarpal TunnelTendonitisTendonitisShoulder BursitisShoulder Bursitishttp://www.everybody.co.nz/gifs/carpal.jpgProblem SpecificationsProblem SpecificationsNo interference with the collection of dataNo interference with the collection of dataReduce force appliedReduce force appliedReduce strain on jointsReduce strain on jointsStill allow for precise movements and adjustmentsStill allow for precise movements and adjustmentsAdaptable Adaptable Able to maintain a stable positionAble to maintain a stable positionDesign Proposal 1: Handle RedesignDesign Proposal 1: Handle RedesignDecouple the ‘push’ Decouple the ‘push’ and ‘pinch’ and ‘pinch’ –Force applied by palmForce applied by palm–Fingers supply precise Fingers supply precise movementsmovementsUse splint to support Use splint to support wristwristDesign Proposal 1: Handle RedesignDesign Proposal 1: Handle RedesignAdvantagesAdvantages–Allows mobilityAllows mobility–Prevents wrist strain by reducing pinch forcePrevents wrist strain by reducing pinch force–Can be used for many proceduresCan be used for many proceduresDisadvantagesDisadvantages–Does not prevent strain on shoulder and upper armDoes not prevent strain on shoulder and upper arm–Still must apply a large force for a long timeStill must apply a large force for a long time–Sanitation concernSanitation concern–May be uncomfortableMay be uncomfortableDesign Proposal 2: Transducer Design Proposal 2: Transducer RedesignRedesignForce is applied using Force is applied using entire hand in ‘handle entire hand in ‘handle bar’ grip positionbar’ grip positionTransducer movement Transducer movement separate from main separate from main handle using elastic handle using elastic material material –Allows for small Allows for small movementsmovementsDesign Proposal 2: Transducer RedesignDesign Proposal 2: Transducer RedesignAdvantagesAdvantages–Applies force with more natural position of handApplies force with more natural position of handNo pinchNo pinch–Can be used for many proceduresCan be used for many proceduresDisadvantagesDisadvantages–May reduce amount of precisionMay reduce amount of precision–Apply a large force for a long timeApply a large force for a long time–Does not prevent strain on shoulder Does not prevent strain on shoulderDesign Proposal 3: Mechanical ArmDesign Proposal 3: Mechanical ArmArm is locked into place to Arm is locked into place to apply forceapply forceArc design Arc design 3 segments attached with 3 segments attached with ball & socket and hinge ball & socket and hinge jointsjointsDesign Proposal 3: Mechanical ArmDesign Proposal 3: Mechanical ArmAdvantagesAdvantages–Manual force not needed for long durationsManual force not needed for long durations–Allows for many positions without ‘twisting’ armAllows for many positions without ‘twisting’ armDisadvantagesDisadvantages–Not applicable to all ultrasound proceduresNot applicable to all ultrasound procedures–Does not allow for fast position adjustmentsDoes not allow for fast position adjustments–Possible stability issue?Possible stability issue?Additional Client RequirementsAdditional Client RequirementsPrefer eliminating applied force Prefer eliminating applied force Currently many ideas for handle redesignCurrently many ideas for handle redesignFocus on echocardiogram and biopsy Focus on echocardiogram and biopsy
