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

Patent number: 8984685Abstract: A patient support apparatus system includes sensors adapted to sense a gesture of a person, or forces exerted by the person on the patient support apparatus, and to control the movement of a component of the patient support apparatus based on the gesture or forces. The movement of the patient support apparatus matches the direction of the person's gesture or applied forces. The speed of the gesture and magnitude of the applied force also influence the movement of the patient support apparatus component. The controlled movement may be the upward and downward motion of a patient support deck on the patient support apparatus, or it may be the pivoting of a section of the patient support deck, or it may be other movement. Control of the patient support apparatus is carried out based on the intent of the user, as evidenced by the user's gesture or applied forces.Type: GrantFiled: February 15, 2013Date of Patent: March 24, 2015Assignee: Stryker CorporationInventors: Donna-Marie Robertson, Rohit Subramanian, Thomas Joseph Newport, II, Richard Thomas Deluca
