Systems, methods, and apparatus are provided for preventing and treating pressure ulcers in bedfast patients. The invention includes providing a non-powered mattress having a first zone adapted to conform to a first body part and a second zone adapted to provide support to a second body part, and off-loading interface pressure on the first body part to the second body part by dynamically increasing the support provided to the second body part by the second zone based on a weight of the first body part on the first zone. The off-loading of interface pressure from the first body part to the second body part equalizes blood oxygen saturation in tissue of the first and second body parts. Numerous additional aspects are disclosed.

An inflatable air mattress device includes a cover internally defining a first and a second receiving zone for receiving a pump and an air mattress therein, respectively. The air mattress includes a plurality of parallelly arranged air cells, each of which internally includes a first air chamber located below a second air chamber and having an elastic member provided therein. The pump is held in the first receiving zone via a movement-limiting mechanism and is provided with an air input and an air release line for communicably connecting to each of the air cells. Since the air cells, the pump and the air input and release lines all are arranged inside the cover, the inflatable air mattress device has an esthetic appearance and occupies less space. The elastic members in the first air chambers prevent a user from contacting with a hard bed frame when the air cells are deflated.

The invention provides a patient supporting plate (2) consisting of at least one first and one second patient supporting components (3, 4) and an accessory part (7). The first or the second patient supporting component (3, 4) is provided with a hinge (5) having a swivel axis (6). The hinge (5) has a drive element (11) for swiveling the patient supporting components (3, 4), as well as at least one coupling element (8) for coupling the first patient supporting component to the second patient supporting component (3, 4). The drive element (11) and the coupling element (8) are arranged juxtaposed in the direction of the swivel axis (6) and can be fastened to one another by means of at least one first detachable fastening element (17). The accessory part (7) can be fastened to the coupling element (8) by means of the first detachable fastening element (17) or a second detachable fastening element (24), by providing a first through opening (14) running in the direction of the swivel axis (6) in the drive element (11) and a second through opening (15) in the coupling element (8) for the first or second fastening element (17, 24) and also an aligned receptacle (16) in the accessory part (7), so that the fastening element (17, 24) can be inserted into the first opening (14) from the drive element (11) side located opposite the coupling element (8) and connected to the accessory part (7).

A nursing bed including a bed body, provided with a plurality of combined bed boards, at least one of the plurality of combined bed boards being provided with one or more pressure sensors, and a comparator, connected to the one or more pressure sensors. The comparator is configured to compare pressure data transmitted by the one or more pressure sensors with a predetermined pressure value and output a warning signal when the pressure data transmitted by the one or more pressure sensors is greater than or equal to the predetermined pressure value. A timer, is connected to the comparator, and with respect to each of the pressure sensors, configured to start timing when the warning signal is received and output an alarm signal when a preset time is reached, and an alarm device, is connected to the timer, and configured to give an alarm after the alarm signal is received.

A pressure offloading device is configured to at least partially wrap around an appendage of a patient. An example pressure offloading device includes an inner layer made of a first foam having a first density and a first indentation force deflection (IFD) rating. The pressure offloading device also includes an outer layer made of a second foam having a second density and a second IFD rating. The inner layer and the outer layer have a U-shape. Additionally, the second IFD rating is greater than the first IFD rating.

A mattress system with at least two inflatable bladders located within a tub compartment of a foam encasement is enclosed. The bladders are surrounded on all sides by foam layers and the bladders are inflated and deflated by a control unit. The control unit is positioned within the tub compartment near the foot of the mattress and centered between the two bladder assemblies. The control unit is adhered to the foam encasement.

A bedding system includes: a bedding; an auxiliary mechanism that is incorporated in the bedding and is to assist change of a body position of the user, the auxiliary mechanism including a plurality of column members that are long along a thickness-wise direction of the bedding, are individually movable along the thickness-wise direction, and are arranged to be parallel to each other; and a first control unit that controls movement of each of the column members.

Modular mattress systems and methods are described. For example, a modular mattress can include a fabric cover configured to surround at least two foam layers. The fabric cover can include an opening to allow access to an interior region of the fabric cover. The mattress can include a first foam layer positioned within the interior region of the fabric cover, and an encasement layer positioned below the first foam layer. The encasement layer can include a recess configured to receive one or more modular support sections. The mattress can also include a plurality of modular support components received within the recess of the encasement.

A double-shell helmet is disclosed. The double-shell helmet includes an outer shell, an impact absorbing material layer affixed to the outer shell on a first side of the impact absorbing material layer, an inner shell affixed to the impact absorbing material layer on a second side of the impact absorbing material layer opposite the first side of the impact absorbing material layer, and a foam layer affixed to the inner shell.

Described herein is a chair for relieving pressure points from prolonged sitting. The chair comprises a plurality of armrests, the armrests comprising: an armrest frame; a foam layer coupled to an upper portion of the armrest frame; and a first gel infused foam layer coupled to an upper portion of the foam layer. The chair further comprises a seat bottom, the seat bottom comprising: a seat bottom frame; a sinuous spring base coupled to the seat bottom frame; a plurality of coil springs coupled to the sinuous spring base; and a second gel infused foam layer coupled to the coil springs. The chair further comprises a seat back, the seat back comprising: a seat back frame; elastic webbing coupled to the seat back frame; and one or more cushions coupled to the seat back frame.
