  • Patent number: 10952644
    Abstract: A location detection system identifies the locations of medical devices such as patient support apparatuses and/or patient care devices within a medical facility. The devices communicate via a wired connection to one or more medical facility systems (e.g. nurse call system, computer network, etc.), and/or via a wireless connection to such systems. The location detection system automatically determines location information of the devices and communicates the location information so that the recipient of any outgoing alerts and/or other information sent from the devices is apprised of the location of the particular device sending the alert or other information. Caregivers are thereby able to respond to the correct location of an alert, and software systems such as EMR systems, admission discharge and transfer (ADT) systems, etc. are able to correlate transmitted device data with the location and/or patient assigned to that location.

  • Publication number: 20200297564
    Abstract: A patient support, such as a mattress, includes a plurality of inflatable bladders. Depth sensors are included in the support that measure the degree of penetration of a patient into the mattress. An air pressure sensor is also included that measures the pressure inside at least one bladder. A suitable inflation level of the mattress is determined by monitoring the rate of change of the depth with respect to air pressure as the bladder is either inflated or deflated. By detecting an inflection point in the graphical relationship of the depth and pressure outputs, a suitable inflation point for the bladders is determined that reduces interface pressures experienced by the patient, yet does not overly sink the patient into the mattress to a degree of discomfort. Analyzing the outputs of the depth and pressure sensors can also be used to detect a patient's heart rate and respiration rate.
