An oximeter device has an ergonomically shaped enclosure that allows a user to comfortably grip and use the device during handheld operation. A sensor tip can be easily placed evenly on the tissue surface, so that all sources and detectors are directly on the tissue with even pressure. This allows for more consistent and accurate results. The user can easily move the device from one position to another and take numerous measurements. The user will have a wide, unobstructed view of the tissue because of the tip’s small size, angle of display, and the grip and fingers are positioned away from the tip. Components housed by the enclosure are arranged to give the device a balanced weighting while in the hand. The device can be used for long periods at a time without fatigue.一種血氧計裝置具有人體工學形狀之外殼，容許使用者在手持操作期間舒適地抓持及使用裝置。感測器末端可以輕易平衡地放置於組織表面上，使得所有光源及偵測器以均勻壓力直接施加於組織上。此即提供較為一致且準確的結果。使用者可以方便從一位置移動裝置到另一位置，並且進行多次測量。使用者有寬廣、無遮阻的組織視野，因為末端體積小、顯示器角度、且握柄與手指皆位於遠離末端處。由外殼覆蓋之組件係配置成賦予裝置在握於手中時有平衡的重壓。裝置可以長期使用且不致令人疲累。
