Control Interface For A Medical Monitor
The present disclosure describes the use of virtual control structures on medial devices, such as medical monitors. The virtual control structures may be implemented as virtual knobs, virtual sliders, or as other structures suitable for adjusting an operational parameter of the medical or other device. When displayed on a touch screen, the virtual control structures may be manipulated to adjust the operational parameter. When not in use, the virtual control structure may be hidden or minimized, allowing the touch screen to be primarily used for the display of patient data or operational data for the device.
1 . A medical monitor, comprising:
a touch sensitive display; and
data processing circuitry capable of causing the touch sensitive display to display a virtual control structure, of receiving an input when the virtual control structure is manipulated by a continuous motion applied to the touch sensitive display, and of adjusting a selected parameter based upon the input.
2 . The medical monitor of claim 1 , wherein the data processing circuitry is capable of receiving a prompt via the touch sensitive display that causes the virtual control structure to be displayed.
3 . The medical monitor of claim 1 , wherein the virtual control structure comprises one of a virtual knob or a virtual slider.
4 . The medical monitor of claim 1 , wherein the data processing circuitry is capable of hiding or minimizing the virtual control structure after the selected parameter is adjusted.
5 . The medical monitor of claim 1 , wherein the data processing circuitry is capable of providing an audible indication when the virtual control structure is manipulated.
6 . The medical monitor of claim 1 , wherein the input is based upon the extent or distance of the continuous motion.
7 . The medical monitor of claim 1 , wherein the input is based upon the speed of the continuous motion.
8 . A medical monitoring system, comprising:
a sensor suitable for acquiring data related to a physiological characteristic of a patient;
a monitor comprising:
a touch sensitive display;
data processing circuitry capable of causing a virtual knob to be to displayed on the touch sensitive display in response to a user prompt, of receiving an input based upon manipulation of the virtual knob, and of adjusting a parameter of the monitor in response to the input.
9 . The medical monitoring system of claim 8 , wherein the data processing circuitry is also capable of receiving the data acquired by the sensor, of generating a measure of the physiological characteristic based upon the data, and of displaying the measure.
10 . The medical monitoring system of claim 8 , wherein the data processing circuitry causes the virtual knob to appear to be depressed when the virtual knob is touched.
11 . A medical monitor, comprising:
a touch sensitive display; and
data processing circuitry capable of causing the touch sensitive display to display a virtual knob and capable of adjusting a parameter of the medical monitor in response to manipulation of the virtual knob.
12 . The medical monitor of claim 11 , wherein the data processing circuitry is capable of hiding or minimizing the virtual knob when the parameter is not being adjusted.
13 . The medical monitor of claim 11 , wherein the data processing circuitry is capable of causing the virtual knob to be displayed on a right side or a left side of the touch sensitive display based upon a user identity or preference.
14 . The medical monitor of claim 11 , wherein the data processing circuitry is capable of audibly indicating when the virtual knob is manipulated.
15 . The medical monitor of claim 11 , wherein the data processing circuitry is capable of altering the appearance of the virtual knob when the virtual knob is touched.
16 . The medical monitor of claim 11 , wherein the data processing circuitry is capable of altering the position of the virtual knob when the virtual knob is touched.
17 . The medical monitor of claim 11 , wherein the data processing circuitry adjusts the parameter in response to an extent or degree by which the virtual knob is rotated.
18 . The medical monitor of claim 11 , wherein the data processing circuitry adjusts the parameter in response to a rate at which the virtual knob is rotated.
19 . The medical monitor of claim 11 , wherein the rate at which the parameter is adjusted is based upon a distance between a center of the virtual knob and a contact point where the virtual knob is touched while being manipulated.
20 . The medical monitor of claim 11 , wherein the virtual knob comprises two or more regions that can be independently manipulated.
