Low air loss moisture control mattress overlay

Disclosed are apparatus and methodology for controlling humidity (i.e., moisture) within and / or adjacent a coverlet associated with a multi-layer air mattress. Humidity sensors may be incorporated at selected locations within the coverlet and coupled to a controller that is configured to provide a closed-loop control signal to vary air flow rate through the coverlet to control the rate of moisture adjustment, such as removal. In part, present subject matter may include a combination of a Low-Air-Loss (LAL) topper, having a pair of humidity sensors, one of which is at an inlet to the LAL topper and the other of which is at a selected one of existing outlets of the LAL topper. Air flow through the LAL topper is kept constant, in accordance with its basic operation, while the two humidity sensors are part of a closed-loop feedback control system, which adjusts the humidity of the air being input at the inlet. Additionally portions of a closed-loop feedback control system may depend on the sensed rate of change of moisture, to facilitate more rapid response to changing moisture conditions. Separately, and not as part of the control feedback loop, a temperature sensor may be provided for simply indicating the temperature of the air relative to the LAL topper.

Segmented pneumatic pad for regulating pressure upon parts of the body during usage

A compression garment for selective application for treatment of lymphedema and prevention of local ischemia of tissues at various locations of the body. The garment includes a pair or series of layers of hermetically sealed material, that can capture pressurized air, when applied therein, and is formed through the patterned sealing of the layers of the garment together, at select locations, to form air pockets that can selectively apply isolated points of pressure to the patient's affected area, without disrupting normal vascular and lymphatic functioning. The garment is design cut, for application to various segments of the body, and applies encompassing pressure over the entire affected area, and includes valves that can allow for the injection of measurable air, to the desired pressure points, or its deflation, after treatment. The compression device of this invention may also be formed as a segmented pad or mat, into which pneumatic pressurized air may be applied, at various segments, so as to regulate the amount of pressure applied to the surface of the body that is in contact with the pad or mat of this invention.

Inflatable mattress and control methods

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 reduced interface pressures experienced by the patient, yet does not overly sink the patient into the mattress to a degree or discomfort. Analyzing the outputs of the depth and pressure sensors can also be used to detect a patient's heart rate and respiration rate.

Mattress cover for convalescing patient

There is provided an inflatable mattress and coverlet used to reduce and treat decubitus ulcers. The mattress is an air inflatable mattress and is particularly adapted for use on a bed in a hospital, nursing home, health care facility or the like. The air inflatable mattress has a series of apertures on the top allowing small amounts of air to pass through to the underside of the coverlet. According to one aspect of the invention the coverlet is placed over the top of air inflatable mattress in the central portion thereof between the head of the bed and the foot of the bed. The coverlet is of sufficient length to extend under the weight bearing portions of the patient. The coverlet has as a first layer a moisture wicking fabric, such as a polyester, and on one side of the moisture wicking fabric there is attached a microporous polymeric member which allows air from the mattress to pass through the coverlet to the patient. Adjacent the polymeric member is another layer comprising a spacer fabric. The side edges of the coverlet form a drip edge and may be attached to the mattress by suitable means.

The invention consists in an inflatable ultralight parachute deployable before jumping, for jumping or releasing a load from any altitude, without experiencing unduly harm from the impact with the ground. It comprises at least one torus-shaped inflatable tube covered by a thin film substantially flat shroud whose buoyance lifts the parachute and when pulled down by the gravity of the attached body develops the braking force that decelerates its fall. The ultralight parachute is deployed either by the jumper if he has one, or by emergency helpers on the ground and subsequently lifted to the potential jumper. Optional accessories that enhance the braking force of the parachute and attenuate the impact of the attached body with the ground, include an aerodynamically shaped inversed skirt surrounding the torus-shaped tube, an electro-mechanical reel that upon activation shortest the distance between the jumper and the canopy and an air mattress that floats beneath the jumper's feet for reducing the impact of the fall when hitting the ground.
