A valve for an inflatable device includes a pocket configured to be located in a cavity of the inflatable device. The pocket includes an entrance opening to receive air from an air output. The pocket further includes a first layer of material having at least a first aperture, wherein the first aperture is positioned entirely within the first layer of material, a second layer of material having at least a second aperture in fluid communication with the first aperture, wherein the second aperture is positioned entirely within the second layer of material. The first aperture and the second aperture are in fluid communication with the entrance opening and the cavity such that airflow passes through the valve by flowing from the entrance opening into the pocket, and out of the pocket and into the cavity through at least one of the first aperture or the second aperture.

A pressure-controlling device (10) includes a pump (21), a connection pipe (30), a first valve (41), and a second valve (42). The pump (21) has an inlet port (211) and an outlet port (212). The connection pipe (30) has a first end in communication with the outlet port (212), and a second end in communication with the inlet port (211) and that has a first space (31) that contains the first end, a second space (32) that contains the second end, and a third space (33) that is located between the first space (31) and the second space (32).

A system for monitoring medical conditions including pressure ulcers, pressure-induced ischemia and related medical conditions comprises at least one sensor adapted to detect one or more patient characteristic including at least position, orientation, temperature, acceleration, moisture, resistance, stress, heart rate, respiration rate, and blood oxygenation, a host for processing the data received from the sensors together with historical patient data to develop an assessment of patient condition and suggested course of treatment, including either suspending or adjusting turn schedule based on various types of patient movement. Compliance with Head-of-Bed protocols can also be performed based on actual patient position instead of being inferred from bed elevation angle. The sensor can include bi-axial or tri-axial accelerometers, as well as resistive, inductive, capacitive, magnetic and other sensing devices, depending on whether the sensor is located on the patient or the support surface, and for what purpose.

A patient support apparatus may include a support surface configured to conduct air along a top face of the support surface so that heat and moisture from a patient lying on the support surface are drawn away from the top face of the support surface. An opening may be formed in a side of the support surface. A cavity may extend from the opening into the support surface. An inlet port may be positioned within the cavity and fluidly coupled to the top face. A blower assembly may be configured to position within the cavity. The blower assembly may have an outlet port that couples to the inlet port when the blower assembly is positioned within the cavity. The blower assembly may conduct air through the inlet port to the top face of the support surface.

A patient support apparatus includes a bed including a frame. A mattress is supported by the frame. A respiratory therapy apparatus is supported by the frame. A pneumatic system is operable to inflate at least one bladder of the mattress and operable to deliver air to the respiratory therapy apparatus.

An auto-inflating cushion structure includes an outer covering and an inner filling body. The inner filling body is accommodated in the outer covering and has a three-dimensional shape in a normal state. The outer covering is provided with an air valve unit. When not in use, the cushion can be compressed to become thin, thereby reducing the volume without occupying space. When in use, the external air flows into the outer covering, in cooperation with the expansion of the inner filling body, so that the interior of the cushion is automatically inflated. The cushion can serve as an auxiliary support for a user lying on his/her side. In particular, the storage is quite space-saving and the cushion is practical.

This disclosure provides a patient support for supporting a patient. The patient support comprises a lattice of cells each having a base, a top disposed opposite the base, and one or more buckling elements having a thickness and extending from the base to the top to form a column.

A patient support apparatus includes a support surface including a topper. An opening is formed in a side of the support surface. A cavity extends from the opening into the support surface. An inlet port is positioned within the cavity and fluidly coupled to the topper. A pneumatic blower is configured to removably position within the cavity and has an outlet port that couples to the inlet port.

A mattress has a first support portion configure to receive and support a first user and a second support portion configured to receive and support a second user. The first support portion and the second support portion are adjacent to each other such that the first user is capable of rolling over from the first support portion to the second support portion while sleeping on the first support portion. A sensor is configured to sense first pressure in the first support portion and sense second pressure in the second support portion. The sensor is further configured to transmit data of the first pressure and the second pressure. The controller is configured to receive the data and from the data of the first pressure and the second pressure, determine if the first user has rolled over from the first support portion to the second support portion.
