Infusion pump touchscreen with false touch rejection

Abstract

An infusion pump is configured to reject an input as a false touch. The infusion pump includes a touchscreen display configured to display infusion pump information and to receive a touchscreen input, a processor in communication with the touchscreen display, and a memory. The memory stores instructions that when executed by the processor, cause the processor to execute a false touch rejection process. The false touch rejection process includes receiving the touchscreen input corresponding to a contact with the touchscreen display, determining a contact parameter from the touchscreen input, determining from the contact parameter, that the touchscreen input corresponds to a false touch, and rejecting the touchscreen input.

What is claimed is: 
     
         1 . An infusion pump configured to reject an input as a false touch, the infusion pump comprising:
 a touchscreen display configured to display infusion pump information and to receive a touchscreen input;   a processor in communication with the touchscreen display; and   a memory in communication with the processor and configured to store instructions that when executed by the processor cause the execution of a false touch rejection configured to:
 receive the touchscreen input corresponding to a contact with the touchscreen display of the infusion pump; 
 determine a contact parameter from the touchscreen input; 
 determine, from the contact parameter, that the touchscreen input corresponds to a false touch; and 
 reject the touchscreen input. 
   
     
     
         2 . The infusion pump of  claim 1 , wherein the touchscreen display is configured to receive the touchscreen input by sensing a change to an electromagnetic field. 
     
     
         3 . The infusion pump of  claim 1 , wherein the touchscreen display is configured to receive the touchscreen input by sensing a change in capacitance. 
     
     
         4 . The infusion pump of  claim 1 , wherein the instructions configure the processor to determine the contact parameter by determining a shape of the contact corresponding to the touchscreen input. 
     
     
         5 . The infusion pump of  claim 1 , wherein the instructions configure the processor to determine the contact parameter by determining a position of the contact corresponding to the touchscreen input. 
     
     
         6 . The infusion pump of  claim 1 , wherein the instructions configure the processor to determine the contact parameter by determining a movement the contact corresponding to the touchscreen input. 
     
     
         7 . The infusion pump of  claim 1 , wherein the instructions configure the processor to determine that the touchscreen input corresponds to a false touch by determining that a position of the contact corresponding to the touchscreen input moves in a downward direction. 
     
     
         8 . The infusion pump of  claim 1 , wherein the instructions configure the processor to determine that the touchscreen input corresponds to a false touch by determining that a volume of the contact corresponding to the touchscreen input increases over time. 
     
     
         9 . The infusion pump of  claim 1 , wherein the instructions configure the processor to determine that the touchscreen input corresponds to a false touch by determining that a width of the contact corresponding to the touchscreen input remains constant and a height of the contact increases over time. 
     
     
         10 . The infusion pump of  claim 1 , wherein the instructions configure the processor to determine that the touchscreen input corresponds to a false touch by determining that a lower edge of the contact corresponding to the touchscreen input is positioned at or near a lower edge of the touchscreen and that a height of the contact decreases over time. 
     
     
         11 . The infusion pump of  claim 1 , wherein the instructions configure the processor to determine that the touchscreen input corresponds to a false touch by determining that a height of the contact corresponding to the touchscreen input is or is at least 2, 3, 4, 5, or more times the width of the contact. 
     
     
         12 . The infusion pump of  claim 11 , wherein the instructions configure the processor to determine that the touchscreen input corresponds to a false touch by determining that a position of the contact corresponding to the touchscreen input does not change over a predetermined time period. 
     
     
         13 . The infusion pump of  claim 11 , wherein the instructions configure the processor to determine that the touchscreen input corresponds to a false touch by determining that a position of the contact corresponding to the touchscreen input changes in a horizontal direction over a predetermined time period. 
     
     
         14 . A method of rejecting input as a false touch to a touchscreen display of a medical device, the method comprising:
 receiving a touchscreen input corresponding to a contact with a touchscreen display of a medical device;   determining a contact parameter from the touchscreen input;   determining, from the contact parameter, that the touchscreen input corresponds to a false touch; and   rejecting the touchscreen input.   
     
     
         15 . The method of  claim 14 , wherein receiving the touchscreen input comprises sensing a change to an electromagnetic field. 
     
     
         16 . The method of  claim 14 , wherein receiving the touchscreen input comprises sensing a change in capacitance. 
     
     
         17 . The method of  claim 14 , wherein determining a contact parameter comprises determining a shape of the contact corresponding to the touchscreen input. 
     
     
         18 . The method of  claim 14 , wherein determining a contact parameter comprises determining a position of the contact corresponding to the touchscreen input. 
     
     
         19 . The method of  claim 14 , wherein determining a contact parameter comprises determining a movement the contact corresponding to the touchscreen input. 
     
     
         20 . The method of  claim 14 , wherein determining that the touchscreen input corresponds to a false touch comprises determining that a position of the contact corresponding to the touchscreen input moves in a downward direction.
