Portable patient monitor
First Claim
1. A portable patient monitoring device including navigation by feel functionality, the device comprising:
- electronic circuitry capable of receiving a signal output from a light sensitive detector capable of detecting light attenuated by body tissue carrying pulsing blood, wherein the electronic circuitry is also capable of outputting audio or visual indicia indicative of one or more physiological parameters of the body tissue;
a housing including a top side;
a plurality of user input keys arranged on the top side of the housing along the periphery of at least two substantially parallel curves;
a protective cover comprising a pliable material;
at least one alignment edge substantially parallel to the two curves, a portion of said at least one alignment edge being raised substantially above a substantially planar surface of said top side of said housing, said edge locatable by feel of the user to guide the user to the plurality of user input keys.

Abstract
Embodiments of the present disclosure includes a portable pulse oximeter, such as a handheld pulse oximeter, that provides a user with intuitive key navigation for device operation, which reduces an amount of visual concentration needed to handle and operate the oximeter. In various embodiments, the portable pulse oximeter includes one or more of user input keys disposed along curve, an alignment edge providing guidance by feel of a user'"'"'s digits to the input keys, raised convex keys also providing navigation by feel, a protective boot disposed around various portions of the oximeter housing to protect against impacts, a table-top stand, combinations of the same, or the like.

20. A patient monitor comprising:
-
a handheld housing including a generally planer top surface, said housing having a periphery at least partially comprising a pliant material capable of reducing an effect of an impact against said housing; a plurality of displays arranged on the generally planer surface in a generally flush manner with said surface, at least two of said plurality of displays are configured to display visual indicia different from one another yet both responsive to physiological parameters of a patient being monitored; a plurality of user keys raised above said generally planer surface, said user keys being locatable-by-feel by a holder of the patient monitor; a guide surface raised above said generally planer surface in an area proximate said user keys, said guide surface substantially flush with said generally planer surface in an area proximate said displays such that said guide surface rises from a flush position to a raised position between said area proximate said displays to said area proximate said user keys in a substantially uniform manner along a length thereof, said guide surface providing a locate-by-feel mechanism for a user seeking the user keys with the user'"'"'s fingers.
