Identifying when a USB self-powered device is connected to a medical device by triggering an alert about a potential risk to patient

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.

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.

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 that a universal serial bus (USB) peripheral device connected to the 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, provide 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.

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;
• or
• 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.
