Fingertip Oximeter and a Method for Observing a Measurement Result Thereon

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.

         8 . A method for updating a display mode of a measurement result of a fingertip oximeter on a display, the display mode including a heading and measurement parameters illustrating the measurement result, the method comprising:
 displaying, on the display, a first display mode of the fingertip oximeter;   receiving a user instruction for updating the first display mode of the fingertip oximeter;   generating, by a processor, a second display mode according to the user instruction, the second display mode displaying the measurement parameters in a different way than the first display mode; and   displaying, on the display, the second display mode in place of the first display mode, wherein an orientation of the heading of at least one of the first display mode and the second display mode is substantially perpendicular with an orientation of the measurement parameters.   
     
     
         9 . The method of  claim 8 , wherein the measurement parameters are displayed in an upright standing way, a portrait right laying way, a landscape upside-down standing way, or a portrait left laying way. 
     
     
         10 . The method of  claim 8 , wherein at least one of the first display mode and the second display mode further includes a pulse column, and the orientation of the corresponding heading is substantially perpendicular with an orientation of the pulse column. 
     
     
         11 . A fingertip oximeter capable of updating a display mode of a measurement result, the display mode including a heading and measurement parameters illustrating the measurement result, the fingertip oximeter comprising:
 a display configured to display a first display mode of the measurement result;   a button configured to receive a user instruction to update a first display mode; and   a processor configured to generate a second display mode according to the instruction, the second display mode displaying the measurement parameters in a different way than the first display mode, and to cause the second display mode to be displayed in place of the first display mode on the display;   wherein an orientation of the heading of at least one of the first display mode and the second display mode is substantially perpendicular with an orientation of the measurement parameters.   
     
     
         12 . The fingertip oximeter of  claim 11 , wherein the measurement parameters are displayed in an upright standing way, a portrait right laying way, a landscape upside-down standing way, or a portrait left laying way. 
     
     
         13 . The fingertip oximeter of  claim 11 , wherein at least one of the first display mode and the second display mode further includes a pulse column, and the orientation of the corresponding heading is substantially perpendicular with an orientation of the pulse column. 
     
     
         14 . The fingertip oximeter of  claim 11 , further comprising a button scanning unit configured to detect a pressing down of the button. 
     
     
         15 . A fingertip oximeter capable of updating a display mode of a measurement result, the display mode including a heading, a pulse column, and measurement parameters illustrating the measurement result, the fingertip oximeter comprising:
 a display configured to display a first display mode of the measurement result;   a button configured to receive a user instruction to update the first display mode; and   a processor configured to generate a second display mode according to the instruction, the second display mode displaying the measurement parameters in a different way than the first display mode, and cause the second display mode to be displayed in place of the first display mode on the display,   wherein an orientation of the heading of at least one of the first display mode and the second display mode is substantially perpendicular with an orientation of the measurement parameters, and an orientation of the pulse column in the first display mode is the same as an orientation of the pulse column in the second display mode.   
     
     
         16 . The fingertip oximeter of  claim 15 , wherein the measurement parameters are displayed in an upright standing way, a portrait right laying way, a landscape upside-down standing way, or a portrait left laying way. 
     
     
         17 . The fingertip oximeter of  claim 15 , further comprising s a button scanning unit configured to detect a pressing down of the button.
