A system is provided for monitoring a patient on an air support system. The system comprises a capacitive sensor system having a capacitive sensor positioned at the underside of an air filled mattress, and a respiration signal processing module that receives the output of the capacitive sensor system and is configured to monitor patient respiration. Respiration is monitored by: periodically sampling the capacitive sensor system output to obtain measurements of incremental body displacement; analyzing a plurality of the samples to determine one or more values for parameters of patient respiratory rate; and determining when one or more of the parameter values indicate abnormal respiration. A corresponding method and computer program are also provided.

A filler formed to fit underneath a bed frame is provided. The filler includes a membrane. The membrane may include a top layer, bottom layer, and a sidewall connecting the top layer and the bottom layer together. An internal pocket is formed within the membrane. The internal pocket is capable receiving and retaining a gas, thereby making the membrane an inflatable membrane. A valve is secured to the membrane and forms a fluid connection from the internal pocket to an outside, allowing users to inflate and deflate the membrane.

The present invention relates to fittings and an interior conduit to providing a continuous air flow path from a vertical wall of the box spring to a horizontal surface of the box spring to selectively supply to an inflatable volume integrated into a top surface of the box spring. Fittings are provided on a vertical wall for connection to an external source of air. Another set of fittings are provided on a top surface of the box spring for connection to an inflatable bladder. A conduit inside the box spring is connected to an interior nozzle on each of the fittings to provide a continuous flow path from the fittings on the vertical to the fittings on the horizontal surface. The side wall fittings allow an external source of air to be supported or alternatively provide a stable connection for a conduit. With such a configuration, a mattress being supported by a box spring can be maneuvered under the influence of the inflatable bladder without affecting the external source of air.

An air supply apparatus is between an air mattress and a foundation including transverse openings. The air supply apparatus elevates the air mattress and includes a transverse air bladder; a connection assembly including a first line having one end connected to an outlet of an air compressor and communicating therewith, a female connector at the other end of the first line, a check valve in the female connector and communicating with the first line, a second line having the other end coupled to the air bladder by passing through the transverse openings so as to communicate with the air bladder, and a male connector at one end of the second line and including a port wherein the female connector is inserted into the male connector to connect the check valve and the port together; and straps on a top of the foundation for fastening the air bladder thereon.

A valve assembly for controlling fluid communication between fluid chambers in a device such as an inflatable device includes a valve body having first and second ports for fluidly connecting to first and second fluid chambers, and defining a plurality of primary valve seats in series between the ports. A plurality of compound valves are within the valve body and each includes a primary valve member movable to close or open one of the primary valve seats, and a secondary valve member movable to close or open a secondary valve seat in the primary valve member.

An inflatable mattress has an upper layer structure, an inflatable middle layer and a bottom layer structure. The upper layer structure includes a basic fabric layer and a covering layer. The basic fabric layer is woven by a plurality of fabric fibers, wherein the number of weft and warp fibers per square inch is higher than 100. The covering layer and the basic fabric layer stick to each other by glues, wherein the weight of the glues are higher than 20 grams per square yard and lower than 80 grams per square yard. The basic fabric layer orients toward the direction of the coverage layer, pressing and embedding into the covering layer and constituting a fabric surface laminating material.

An outdoor sleeping mat and a sleeping mat set includes a sleeping mat main body, a plurality of transverse supporting belts and a plurality of vertical supporting belts. The sleeping mat main body has a cavity, and the transverse supporting belts and the vertical supporting belts are disposed in the cavity and connected to the sleeping mat main body. The plurality of vertical supporting belts are distributed at two sides of the sleeping mat main body in a width direction, and the plurality of transverse supporting belts are arranged side by side in a length direction of the sleeping mat main body. The outdoor sleeping mat enhances the structural reliability of the sleeping mat main body through the plurality of transverse supporting belts and the plurality of vertical supporting belts, so that the whole outdoor sleeping mat has better supporting performance.

An air cushion structure includes an upper surface layer, an upper pull strap, an upper isolating layer, a lower isolating layer, a lower pull strap, and a lower surface layer. A plurality of upper air chambers are formed between the upper surface layer and the upper pull strap. A plurality of lower air chambers are formed between the lower pull strap and the lower surface layer. A plurality of middle air chambers are formed between the upper isolating layer and the lower isolating layer. Thus, the air cushion structure contains multiple air chambers to provide a better support, and to provide a warming effect.

The invention relates to a device for supporting a body or part of a body, in particular a human body, said device comprising a support element (2) including a seat (3) and a peripheral sidewall (4), such as to define a housing (5) having a bottom (6) and a peripheral side face (7), and a pneumatic element (9) comprising a base (10) and inflatable cells (11) fitted inside the housing (5) and extending between the bottom (6) of the housing and the base (10) of the pneumatic element (9). According to the invention, the peripheral sidewall (4) comprises at least one inner retaining bead (8) at a distance from the bottom (6) of the housing (5), and, when inflated, at least some of the inflatable cells (11a) adjacent to the retaining bead (8a) can be engaged laterally between the retaining bead (8) and the bottom (6) of the housing (5).

A configurable, adjustable inflatable device including one or more inflatable bladders and a shape-defining member that combines with the inflatable bladders such that an overall shape of the configurable inflatable device is at least partially controlled by the shape-defining member.
