Check chip for sensor measuring device

Abstract

A check chip of a sensor measuring device is provided with a structural characterizing portion of a convex shape, concave shape or a penetration hole at a location where a user is considered to pick the check chip up. The state of the structural characterizing portion is made to be different from that of a structural characterizing portion provided on a correction chip which is similar to the check chip, in size, the number of the structural characterizing portions, or placement location. Therefore, the difference from the correction chip can be easily identified even by a visually handicapped person or a weak-sighted person, according to the difference in the structural characterizing portion, from feel, thereby preventing the person from using the check chip and the correction chip with confusion.

What is claimed is:  
     
         1 . A check chip having a similar shape to a measuring sensor, to be mounted on a measuring device to check operations of the measuring device for measuring a specified component in a sample using the measuring sensor, 
 said check chip comprising a sensor body with at least one structural characterizing portion provided thereon, said at least one structural characterizing portion allowing a user of the measuring device to recognize a difference from a correction chip having a similar shape to a measuring sensor and at least one structural characterizing portion thereon, said correction chip being for correcting errors in the measuring device, and    said at least one structural characterizing portion of the check chip has a shape which can be recognized by the user from the touch, and said at least one structural characterizing portion is provided in a location where the user is considered to pick said check chip up, said user loads in the measuring device touching the at least one structural characterizing portion of the check chip.    
     
     
         2 . The check chip of  claim 1 , wherein 
 the difference between said check chip and the correction chip resides in a size of the at least one structural characterizing portion provided on each chips.    
     
     
         3 . The check chip of  claim 2 , wherein 
 the size of the structural characterizing portions provided on said check chip is larger than the size of the structural characterizing portions provided on the correction chip.    
     
     
         4 . The check chip of  claim 2 , 
 wherein the size of the structural characterizing portions provided on said check chip is smaller than the size of the structural characterizing portions provided on the correction chip.    
     
     
         5 . A check chip of  claim 1 , wherein 
 the difference between said check chip and the correction chip resides in a number of the at least one structural characterizing portion of said check chip.    
     
     
         6 . A check chip of  claim 5 , wherein 
 the number of the structural characterizing portions provided on said check chip is larger than the number of the structural characterizing portions provided on the correction chip.    
     
     
         7 . A check chip of  claim 5 , wherein 
 the number of the structural characterizing portions provided on said check chip is smaller than the number of structural characterizing portions provided on the correction chip.    
     
     
         8 . A check chip of  claim 1 , wherein 
 the difference between said check chip and the correction chip resides in a shape of the at least one structural characterizing portion of said check chip.    
     
     
         9 . The check chip of  claim 1 , wherein 
 the at least one structural characterizing portion of said check chip has a convex shape comprising epoxy resin containing silica powder and has a resistor indicating a constant resistance value buried therein.    
     
     
         10 . The check chip of  claim 1 , wherein 
 the at least one structural characterizing portion of said check chip and the at least one structural characterizing portion of the correction chip are located at handle ends of said check chip and the correction chip, respectively.    
     
     
         11 . A kit for a measuring device, said kit comprising: 
 a correction chip adapted to be mounted on the measuring device for measuring a specified component in a sample using the measuring sensor to correct errors in the measuring device, said correction chip having a similar shape to a measuring sensor and at least one structural characterizing portion of a chip; and    a check chip to be mounted on the measuring device to check operations of the measuring device, said check chip comprising a sensor body with a similar shape to a measuring sensor and at least one structural characterizing portion provided thereon, said at least one structural characterizing portion allowing a user of the measuring device to recognize a difference from said correction chip.    
     
     
         12 . The kit of  claim 11 , wherein 
 the at least one structural characterizing portion of said check chip and the at least one structural characterizing portion of the correction chip are located at handle ends of said check chip and the correction chip, respectively.
