A gradient sequential compression system for preventing deep vein thrombosis includes a pressure-based system controller for controlling transfers of air from a source of pressurized air to inflatable chambers of a limb sleeve, so that a prophylactic modality is provided to the limb. The controller also includes a plurality of feeder valves pneumatically connected to each of the chambers and a microprocessor-based control unit for opening only one of the feeder valves at a time during an inflati...

A method and apparatus for providing concurrent applications of intermittent pneumatic compression therapy and vacuum assisted closure therapy generally comprises a wound dressing for introduction of a negative pressure into a wound on a patient's foot and a foot wrap for application of positive, compressive forces to substantially all of the patients foot. A suction pump, having an associated vacuum sensor and first feedback mechanism, supplies negative pressure to the wound dressing. A ventabl...

A thermally controllable apparatus for use with a predetermined therapeutic support platform apparatus and a thermia fluid producing device, wherein said apparatus includes a first side configuratively disposed adjacent the patient surface of the support platform, a second side disposed adjacent a patient and having a first portion thereof sealably connected to a first portion the first side and a second portion thereof spaced from a second portion of the first side such that there is formed a p...

A manually-powered patient conveyor is disclosed in the form of a continuous belt which reduces friction beneath the patient to enable lateral patient transfer from one patient support surface to another. With the belt positioned beneath the patient, a caregiver can readily grip circumferencial handles on the belt to help pull the patient sideways from one surface to another, while borasilicate glass micro-bubbles or other lubricants are dispersed on the interior of the sleeve-like belt to furth...

A patient support system having multiple patient support layers for reducing and preventing the development of bed sores in bedridden patients. A top patient support surface is provided by an anti-shear cover layer. The anti-shear cover layer being operable to reduce lateral shear forces experienced by a patient moving across the patient support surface. One or more fluid pouches or bladders are provided to form a fluid bladder layer for reducing normal pressures and forces experienced by the pa...

A patient cooling system comprises an inflatable patient mattress having an airflow system and integral manifold incorporated therein and a patient enclosure or tent coupled to the inflatable patient mattress and supported by a framework of inflatable tubes drawing air off of the same air supply used to supply the mattress and to thermally control the area in the tent. The framework of inflatable tubes is divided into left and right sections, which are further subdivided into lower body and uppe...

A method, and apparatus for the controlled acceleration, and/or retardation of the body's inflammatory response generally comprises a foam pad for insertion substantially into a wound site, a heating, a cooling pad for application over the wound site, a wound drape or sealing enclosure of the foam pad, the heating, and cooling pad at wound site. The foam pad is placed in fluid communication with a vacuum source for promotion of the controlled acceleration or retardation of the body's inflammator...

For successful wound healing to occur, the newly formed skin must generate tensile strength through collagen deposition. Measurement of collagen in the granulating wound bed may be predictive of successful wound healing. Existing methods for collagen measurement either require specialized equipment, or do not allow for discrimination of potential interfering molecules. Herein described is an accurate, specific and reliable method to extract and quantify collagen from tissue utilizing high pressu...

A method and apparatus for the introduction to a wound under negative pressure therapy of a wound healing agent, generally comprises a foam pad (11) for insertion substantially into a wound site (12), and a wound drape (13) for sealing enclosure of the foam pad at the wound site. The foam pad is placed in fluid communication with a vacuum source for promotion of fluid drainage. Additionally, the foam pad is predisposed, through grafting or other techniques known to those of ordinary skill in the...

A method and apparatus for the transcutaneous monitoring of blood gases generally comprises a blood gas data acquisition device, a vacuum source and a blood gas transducer unit. The blood gas transducer unit is adapted for application to a patient's skin and administration of a local vacuum at the area of patient application. It further comprises an electrochemical blood gas transducer, well known to those of ordinary skill in the art, which is disposed entirely within the local vacuum at the ar...
