Abstract: A sensing device for acquiring data from a finger. The device includes a carrier board having a stacked portion with a finger side and a canopy side. A tip wing extends from the stacked portion and wraps around the finger. Electrical components are coupled to the carrier board, including a first circuit board on the canopy side of the stacked portion, and one or more optical components electrically on the tip wing. The optical components are configured to transmit light towards the finger and to detect the light from the finger. The carrier board electrically couples the electrical components to acquire the data from the finger. A power system is positioned between the canopy side and the finger side of the carrier board, where the power system provides power to the electrical components via the carrier board. A cover secures the carrier board to the finger.

Abstract: An electrode kit for preparing a medical device for a patient. The electrode kit includes a central support member having a device side and a patient side with one or more perforations are defined between. A conductive material extends through the one or more perforations to couple the patient and the medical device. A device side cover is removably coupled to the device side of the central support member, where the central support member is configured to be coupled to the medical device when the device side cover is removed. A patient side cover is removably coupled to the patient side of the central support member, where the central support member is configured to couple to the medical device to the patent when the patient side cover is removed.

Abstract: A sensing device for acquiring data via a finger. The device includes a wrap having a central portion with a tip wing, a first side wing, and a second side wing each extending therefrom. The wrap has an exterior side and an opposite finger side that faces towards the finger. An electronics system is coupled to the wrap and has a sensor configured to acquire the data from the finger. An adhesive is configured to adhere the sensing device to the finger. First and second attachment portions are positioned on finger side of the first side wing and on the exterior side of the second side wing, respectively, where the first and second attachment portions removably attach to each other to non-adhesively secure the wrap around the finger.
