Abstract: A person support apparatus supports a person in a laying-down or a seated position. One or more body-mounted sensors detect changes in the position of the person relative to a reference. A control system receives output from the body-mounted sensor or sensors through a remote coupling. The control system uses patient position information obtained from the body-mounted sensors to determine whether the person has experienced a change-in-position and/or a change-in-activity event. Alternatively or in addition, the position of the person situated on a person support apparatus is detected using one or more sensors that are not body-mounted, but rather are coupled to the person support apparatus or to another component of a patient support system. The patient position information is used to estimate the patient's torso angle. The estimated torso angle is used to assess the patient's condition.

Abstract: According to the present disclosure, a microclimate system includes a topper and an air box. The topper is configured to conduct air along a surface of the topper so that heat and moisture from a patient lying on the topper are drawn away from the surface. The air box includes a blower coupled to the topper to provide air to the topper to be conducted along the surface of the topper. The air box may also include an environmental sensor unit coupled configured to detect environmental information corresponding to the environment around the microclimate system.

Abstract: Systems for delivery of therapeutic agents and related methods are disclosed. A sensing system is configured to detect a chemical in the vicinity of a patient and transmit a signal to a controller upon detection. A controller is configured to release a therapeutic agent which is transported to the site of interest. The controller communicates with an electronic medical records database, an alarm and a nurse call system.

Abstract: A patient support apparatus includes a patient support surface to support a patient. The patient support surface has at least one air bladder that is inflated and/or deflated to achieve a turn assist function and/or a therapy function of the patient support surface. A graphical user interface (GUI) is configured to receive user inputs from a caregiver to initiate the turn assist or therapy functions. The patient support apparatus has control circuitry coupled to the GUI. The GUI is controlled by the control circuitry to display information indicating that the patient is improperly positioned on the patient support surface for either the turn assist function or the therapy function. Alternatively or additionally, the control circuitry indicates that the patient is improperly positioned for raising a head section of a bed frame.

Abstract: One embodiment of a climate management topper includes a flowpath boundary which defines a flowpath adapted to carry a stream of fluid in a principal direction. A flow compliant filler occupies at least part of the flowpath. The filler is comprised of a spacer and a set of shape change actuators (SCA's) each comprised of a shape change material (SCM). The properties of the SCM include a critical temperature T0. The SCA's are configured to regulate distribution of the fluid stream through the flowpath in a direction transverse to the principal direction as a function of temperature. In one example the flowpath boundary is formed by liner panels and the SCA's are linear elements that elongate at a temperature TH which is higher than T0 thereby distending the spacer and reducing its resistance to fluid flow. One suitable shape change material is a nickel/titanium alloy known as NiTiNOL.

Abstract: A patient support apparatus includes a cushion, a cover arranged over a top side of the cushion, and a sensor unit. The sensor unit is coupled to the cover and arranged to underlie a patient supported on the cover. The sensor unit includes a sensor configured to detect conditions near the interface of a patient's skin with the cover.

Abstract: A person-support surface comprises a non powered mattress and a coverlet positionable on the non powered mattress. The coverlet includes an entry positioned at a first end of the coverlet, an exit positioned at a second end of the coverlet opposite the entry, an upper air impermeable layer, and a lower air impermeable layer coupled to the upper air impermeable layer to form an air flow path along the coverlet between the entry and the exit. The upper air impermeable layer is a vapor permeable and the lower air impermeable layer is a vapor permeable.

Abstract: A method for controlling performance of an MCM capable support surface having a flowpath for guiding a stream of air along at least a portion of the surface, comprises specifying a desired evaporative rate greater than an evaporative rate achievable with unconditioned ambient air, chilling the unconditioned ambient air to a temperature at least as low as that required to achieve 100% relative humidity, thereby demoisturizing the air, and supplying the chilled, demoisturized air to the flowpath.
