Publication number: 20220378636Abstract: 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.Type: ApplicationFiled: August 10, 2022Publication date: December 1, 2022Inventors: Patrick Lafleche, Krishna Sandeep Bhimavarapu, Manikantan Seshadrinathan, Donna-Marie Robertson

Publication number: 20210161462Abstract: A patient support apparatus is provided, such as a bed, cot, stretcher, or the like, that includes a sensor adapted to detect movement of the occupant while the occupant is supported on the support apparatus. A controller monitors outputs from the sensor in response to a mobility assessment control being activated. After monitoring the outputs for a period of time, the controller generates a mobility score based on the outputs from the sensor. In some embodiments, the controller use outputs from the sensor to determine which region of a defined surface area the patient has moved to. The controller records these visited regions over a time period and uses them to generate the mobility assessment. The mobility assessment provides an objective measure of an important factor used in predicting a patient's risk of developing pressure ulcers.Type: ApplicationFiled: February 9, 2021Publication date: June 3, 2021Inventors: Patrick Lafleche, Marko N. Kostic, Sujay Sukumaran, Jonathan Mark Greenbank, Madhu Thomas, Manikantan Seshadrinathan
