Magnetorheological Elastomer And Magnetorheological Fluid For Clinical Wrap
A reinforcing clinical wrap is provided with integral thermal management. The clinical wrap includes a fluid circuit for a heat transfer medium to circulate between a fluid inlet and a fluid outlet. A shape conforming medium is disposed within a portion of the clinical wrap providing selective reinforcement support of the portion of the clinical wrap to conform to a surface of a patient. Non-limiting examples of the shape conforming medium may include a magnetorheological elastomer, a magnetorheological elastomer, a magnetorheological foam, a UV curable resin, and a phase change material.
MEMBRANE-SUPPORTED, THERMOELECTRIC COMPOSITIONS
Thermoelectric devices and methods for making and using the devices and their intermediates are provided. Membrane-supported thermoelectric modules are fabricated by dispensing thermoelectric powder into select locations of a membrane to form electrically isolated columns of thermoelectric material. The powder is then sintered or fused to form thermoelectric elements, which are then electrically connected and combined with thermal interface films to form the modules. The modules are the building blocks of electrical current generating, thermoelectric cooling and heat scavenging thermoelectric devices.
THERMAL SYSTEM WITH PATIENT SENSOR(S)
A thermal control unit supplies temperature controlled fluid to a patient to control the patient's temperature. The thermal control unit includes a fluid outlet, fluid inlet, heat exchanger, pump, patient core temperature probe port, auxiliary sensor port, and controller. The controller receives patient core temperature readings from the patient temperature probe port and auxiliary sensor readings from the auxiliary sensor port. The controller may control a temperature of the circulating fluid in both a feedback manner using patient core temperature readings and a feedforward manner using readings from the auxiliary sensor. The auxiliary sensor may measure a characteristic of the patient's tissue indicative of thermal resistance, and/or the auxiliary sensor may measure a temperature of the patient's tissue at an intermediate depth. The controller may use the intermediate temperature to predict arrival at a target patient temperature. The auxiliary sensor may be an ultrasonic sensor, infrared sensor, or the like.
Water perfusion heat exchange pad for control of skin temperature
Heat exchange pads for use on a patient are described herein. An example heat exchange pad can include a surface defining an internal volume and having a flexible patient contacting portion, an inlet fluidly connected to the internal volume for delivery of fluid into the internal volume, an outlet fluidly connected to the internal volume for removal of fluid from the internal volume, and at least one extended surface structure positioned within the internal volume to disrupt laminar flow of fluid from the inlet to the outlet.
Device for cooling a body region
The invention relates to an device (1) for cooling and/or heating a body region, preferably a head region, comprising at least one thermally conductive skin contact material (2) and at least one Peltier element (3), wherein the Peltier element (3) is connected to the skin contact material (2), wherein a thermally conductive connecting element, in particular a thermally conductive film (5), and a heat dissipation element (12) are provided, wherein heat emitted via an outer side of the Peltier element (3) can be distributed to the heat dissipation element (12) via the connecting element.
Heat exchange module and system for medical applications
A heat exchange module alone or part of a system including a control console. The module includes a channel assembly and a heat exchange stack attached thereto, and can be used to directly cool and/or heat tissue or skin. The channel assembly includes a liquid channel. The stack can include a pair of spaced plates with thermoelectric coolers exchangers, heat reflective layers, and a core composite layer which keeps the plates spaced. To provide flexibility of the module to better fit on round body parts the stack can include a thermally-conductive plate construction between the plates which has rotational flexibility axes in the X and/or Y directions between plate portions. Optionally the channel can include windows to which the plate portions are sealed. The heat exchange stack separately or together with the channel assembly can be secured in the thickness direction with mechanical securements such as sewing or tacking to also provide for greater flexibility.
Heating patch, and warming device for skin care comprising same
Provided is a heating patch. The heating patch includes: a flexible plate-shaped base substrate; an electrode portion including a pair of lead electrodes formed on at least one surface of the base substrate along a longitudinal direction to be spaced apart along a width direction of the base substrate, and a pair of branch electrodes extending from the lead electrodes along the width direction of the base substrate to be not electrically connected to each other and to be overlapped with each other; a heating portion including a conductive heating material disposed in an overlapped part between the branch electrodes which have a predetermined area and face each other to generate heat while conducting the pair of branch electrodes to each other; and a pair of cover members disposed on both sides of the base substrate to prevent the electrode portion and the heating portion from being exposed externally.
Cooling system for circulating cooling fluid ihrough a cooling pad
A cooling system (1) for use in a non-invasive medical cooling process to cool at least one portion of the body of a person (2) by means of a cooling fluid flowing through a cooling pad (3), comprising a first pump 70, a fluid outlet conduit (20), a fluid inlet conduit (40 and; —a second pump (80) arranged to pump cooling fluid through a fluid bypass conduit (60) from the fluid inlet conduit (40) to the fluid outlet conduit (20), wherein—the cooling system (1) is arranged such that cooling fluid is transported from the tank (10) to the fluid outlet conduit (20) when the first pump (70) is operated and such that cooling fluid is transported from the fluid inlet conduit (40) to the fluid outlet conduit when the second pump (80) is operated.
