Abstract

There is provided a fingertip oximeter that has a plurality of display modes which are presented sequentially in a circulating way, allowing users to easily observe a measurement result from any of surrounding directions. The present invention makes users to be able to observe a measurement result of the fingertip oximeter from any of surrounding directions, without the need of bending his/her finger. Thus, any partial occlusion of the arterial blood capillary can be avoided, so that strength of the pulse will not decrease, and strength of the signal will not be affected. As a result, the precision of the measurement is improved.

Claims

1-7. -7. (canceled)

8. A method for displaying a measurement result of a fingertip oximeter on a display, the method comprises:

step

     1) receiving an instruction from a user for updating a current display mode of the fingertip oximeter in use by pressing a button down, said button further controlling a power source of the oximeter, said current display mode illustrating the measurement result, or a heading and the measurement result, said heading being displayed in an upright standing way or an upside-down standing way;

said measurement result including measurement parameters, or measurement parameters and pulse columns, said measurement parameters being displayed in an upright standing way, a portrait right laying way, a landscape upside-down standing way, or a portrait left laying way;

step

     2) updating, by a central processor, the current display mode in use with a new display mode and transmitting a signal regarding the new display mode to the display after detecting pressing-down of the button; and

step

     3) receiving, by the display, the signal regarding the new display mode from the central processor, and presenting an updated measurement result in the new display mode.

9. The method of claim 8, wherein said step 2) further comprises:

detecting instructions for switching the current display mode;

setting a display mode to be switched according to the current display mode;

updating the current display mode according to the display mode to be switched; and

sending the signal for updating the current display mode to the display.

10. A fingertip oximeter comprising:

a signal driven unit;

a signal collection unit;

a power source unit for supplying power to the pulse oximeter;

a button for updating a current display mode in use, said current display mode illustrating measurement result, or a heading and the measurement result, said heading being displayed in an upright standing way or an upside-down standing way, said measurement result including measurement parameters, or measurement parameters and pulse columns, said measurement parameters being displayed in an upright standing way, a portrait right laying way, a landscape upside-down standing way, or a portrait left laying way, wherein said button also controls the power source unit of the pulse oximeter;

a central processor for generating display signal for display an update display mode, and

a display for displaying the updated display mode.

11. The fingertip oximeter of claim 10, wherein said central processor includes:

at least a button scanning unit;

a switch setting unit; and

a display updating unit,

the button scanning unit detecting the pressing down of the button and sending a detection signal to the switch setting unit,

the switch setting unit receiving the pressing down signal from the button scanning unit, setting a display mode to be switched according to current display mode, and sending a display mode switch signal to display updating unit;

the display updating unit receiving the display mode switch signal sent by said switch setting unit, updating the current display mode, and sending an updated display mode signal to the display.
