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 inflammatory response. The heating, and cooling provision controls the local metabolic function as part of the inflammatory response.

Provided is a massaging device including: a housing; an adsorption unit mounted in the housing and adsorbed on the skin so as to be moved along the skin; and a cooling and heating system installed in the adsorption unit to cool or heat the adsorption unit thereby allowing cold and hot thermal energies to directly penetrate into the skin through the adsorption unit contacting the skin. Further, the cold and hot thermal energies generated in the cooling and heating system can act directly on the skin through the adsorption unit, so that the cold and hot thermal energies penetrate deeply into the skin, thereby removing the waste materials, harmful substances and fatigue substances accumulated in the skin.

Described is a blood processing apparatus with a blood flow path and a heat exchanger fluid flow path overlapping the a heat exchanger chamber, in which the blood flows generally from a first end to a second end of the blood processing apparatus, and the heat exchanger fluid flows generally from the second end to the first end. Such counter or countercurrent flow improves heat transfer between the blood and the heat exchanger fluid. The blood processing apparatus includes a housing, a blood inlet, a heat exchanger fluid inlet and a heat exchanger fluid outlet, a heat exchanger core, a cylindrical shell having an annular shell aperture, a blood flow distributor, and a central chamber in fluid communication to a fluid flow distributor.

A chilled-air inhaler device for the alleviation of respiratory symptoms includes a body containing a hollow chamber through which air is forced or drawn past at least an air-chilling surface. In an embodiment the air-chilling surface may include water ice. Connected to the body and hollow chamber at one end is a mouthpiece including an opening that connects from environmental air outside of the hollow chamber to the hollow chamber. Connected to the hollow chamber at a second end is an inlet which connects to a source of air. In an embodiment, the inlet may connect to an external device such blower or nebulizer.

A catheter pump is disclosed. The catheter pump can include an impeller and a catheter body having a lumen in which waste fluid flows proximally therethrough during operation of the catheter pump. The catheter pump can also include a drive shaft disposed inside the catheter body. A motor assembly can include a chamber. The motor assembly can include a rotor disposed in the at least a portion of the chamber, the rotor mechanically coupled with a proximal portion of the drive shaft such that rotation of the rotor causes the drive shaft to rotate, the rotor including a longitudinal rotor lumen therethrough. The motor assembly can also comprise a stator assembly disposed about the rotor. During operation of the catheter pump, the waste fluid flows from the lumen into the chamber such that at least a portion of the waste fluid flows proximally through the longitudinal rotor lumen.

The present application relates to a method for disinfection of a temperature control device for human body temperature control during extracorporeal circulation which temperature control is conducted by use of a heat exchanger and a temperature control liquid circulating through the heat exchanger and the temperature control device. According to the present application, the temperature control device is connected to a temperature control liquid supply and, during operation of the temperature control device for human body temperature control, a disinfectant is selectively added to the temperature control liquid supply upstream of the temperature control device.

A subject's forehead, and underlying pre-frontal cortex may be cooled by positioning a pre-cooled heat transfer pack on the subject's forehead so that the heat transfer pack is in thermal communication with the subject's forehead, the temperature of the pre-cooled heat transfer pack being below 10 Celsius. Thermal communication between the subject's forehead and the heat transfer pack may be maintained for a period of time sufficient to cool the subject's pre-frontal cortex. Cooling of the pre-frontal cortex may slow the metabolic rate of the subject's pre-frontal cortex and/or induce an onset of sleep for the subject.

A cooling element for use within a cooling device of a closed-circuit respirator, includes an element housing, which has a liquid-tight cap and is filled with a coolant, which has a melting point below 50 C., especially below 45 C., preferably below 40 C. A sensor element is arranged in contact with the coolant within the element housing such that the sensor element can be moved in a direction of the gravity acting on the sensor element in the liquid state of the coolant during the use of the closed-circuit respirator by a user of the closed-circuit respirator.

A control system, for controlling a closed-circuit respirator breathing gas circuit, includes a temperature sensor, a temperature-reading unit and with a control unit. The temperature sensor is configured to send a temperature signal in the presence of a corresponding temperature polling. The temperature signal indicates the temperature currently present in an area surrounding the temperature sensor. The temperature-reading unit is arranged in the closed-circuit respirator at a spaced location from the breathing gas circuit and the temperature sensor, and is configured to trigger the temperature polling at the temperature sensor by sending a polling signal, and to receive the temperature signal sent by the temperature sensor. The control unit is signal connected to the temperature-reading unit and is configured to determine the temperature indicated by the temperature signal in the area surrounding the temperature sensor and to output a control signal as a function of this temperature.
