Identifying when a USB self-powered device is connected to a medical device by triggering an alert about a potential risk to patient
First Claim
Patent Images
1. A method, comprising:
- determining whether a universal serial bus (USB) peripheral device is connected to a medical device, the medical device being configured for use in a medical procedure with a patient;
if the USB peripheral device is determined to be connected to the medical device, determining whether the USB peripheral device is drawing power from the medical device; and
if the USB peripheral device is determined to not be drawing power from the medical device, providing an indication of a potentially unsafe condition, the potentially unsafe condition being that the USB peripheral device may be drawing power from a power supply independent of the medical device and thus may present a potential risk to the patient.

17. A medical device, comprising:
-
a memory, the memory configured to store instructions for execution; and one or more processing devices configured to execute the instructions, the instructions for causing the one or more processing devices to; determine whether a universal serial bus (USB) peripheral device is connected to the medical device, the medical device being configured for use in a medical procedure with a patient; if the USB peripheral device is determined to be connected to the medical device, determine whether the USB peripheral device is drawing power from the medical device; and if the USB peripheral device is determined to not be drawing power from the medical device, provide an indication of a potentially unsafe condition, the potentially unsafe condition being that the USB peripheral device may be drawing power from a power supply independent of the medical device and thus may present a potential risk to the patient. - View Dependent Claims (18, 19, 20, 21, 22, 23, 46, 47)

24. One or more computer-readable media storing executable instructions, the one or more computer-readable media comprising tangible media, the instructions for causing one or more processing devices to:
-
determine whether a universal serial bus (USB) peripheral device is connected to a medical device, the medical device comprising the one or more processing devices, the medical device being configured for use in a medical procedure with a patient; if the USB peripheral device is determined to be connected to the medical device, determine whether the USB peripheral device is drawing power from the medical device; and if the USB peripheral device is determined to not be drawing power from the medical device, provide an indication of a potentially unsafe condition, the potentially unsafe condition being that the USB peripheral device may be drawing power from a power supply independent of the medical device and thus may present a potential risk to the patient. - View Dependent Claims (25, 26, 27, 28, 29, 30, 48, 49)

31. A method, comprising:
-
determining that a universal serial bus (USB) peripheral device connected to a medical device is not drawing power from the medical device, the medical device being configured for use in a medical procedure with a patient; and responsively to the determining, providing an indication of a potentially unsafe condition to at least one of a user of the medical device or the patient, the potentially unsafe condition being that the USB peripheral device may be drawing power from a power supply independent of the medical device and thus may present a potential risk to the patient. - View Dependent Claims (32, 50, 51)

35. A method, comprising:
-
monitoring a first universal serial bus (USB) data line and a second USB data line on a medical device, the medical device being configured for use in a medical procedure with a patient; if at least one of the first USB data line or the second USB data line goes to a high state, monitoring an output of a current detection circuit, the output being indicative of whether power is or is not being drawn from the medical device by a USB peripheral device connected to the medical device; and if the output indicates that power is not being drawn from the medical device by the USB peripheral device, performing at least one of the following; electrically isolating the USB peripheral device from the medical device and the patient;
orproviding an indication of a potentially unsafe condition, the potentially unsafe condition being that the USB peripheral device may be drawing power from a power supply independent of the medical device and thus may present a potential risk to the patient. - View Dependent Claims (36, 37, 38, 39, 54, 55)
