Mount for a patient monitoring device
A mount for a device configured to monitor the movements or other activities of patient. Aspects include a monitoring unit and base, where the base may further include a pad with one or more pins extending into the base. The pad may be positioned inside a garment worn by a patient, the pins passing through the garment and electrically connecting to circuits in the fabric of the garment (e.g. a sock worn by the patient). The circuits may include sensors which are response to changes in pressure caused by patient movement. Output from the sensors may be carried by the circuits in the garment to the pins in the pad, and from there through the garment and into the base and the monitoring unit for processing and reporting to caregivers as needed.
