INFUSION PUMP TOUCHSCREEN WITH FALSE TOUCH REJECTION
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.
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.
