An intra vascular temperature management catheter incudes a shaft through which working fluid can circulate to and from a proximal location on the shaft. The catheter extends from a connector hub. At least one heat exchange member is supported by a distal part of the shaft or other part of the catheter to receive circulating working fluid from the proximal location. A temperature sensor is supported on the catheter for generating a temperature signal representative of blood temperature to a control system. The temperature sensor includes first and second conductive leads having respective first and second distal segments on or in the catheter shaft. The first and second distal segments are arranged to be in thermal contact with blood flowing past the catheter when the catheter is disposed in a blood vessel of a patient. Also, the temperature sensor includes a joining body connected to proximal segments of the first and second leads.

NOVEL MASSAGE GUN
20220168175 · 2022-06-02 ·

The present disclosure provides a novel massage gun, relates to the technical field of massage devices, and solves the technical problem that a wire between a handle and a massage head of the massage gun breaks easily when the massage gun moves at a high speed. The novel massage gun includes a gun body, a massage head arranged on the gun body, an auxiliary physiotherapy assembly arranged in the massage head, a main circuit board arranged in the gun body, and a connecting cable electrically connected to the auxiliary physiotherapy assembly and the main circuit board, where the connecting cable is made of a conductive wire resistant to high-speed bending. In the present disclosure, the connecting cable electrically connected to the auxiliary physiotherapy assembly in the massage head is made of the conductive wire resistant to high-speed bending, which solves the problem that the connecting cable breaks easily when the massage gun performs high-speed piston movement. Because the connecting cable does not break easily, electrical connection can be maintained, thereby prolonging the service life of the massage gun, and reducing use costs.

Thermal system with step response

A thermal control unit for controlling a patient's temperature includes a fluid outlet for delivering temperature-controlled fluid to a patient, a pump, a heat exchanger, and a controller that automatically implements a step change in the temperature of the fluid delivered to the patient. The step change is implemented prior to the patient reaching a target patient temperature. In the moments after (and in some cases the moments before) the step change, the controller monitors the rate of change of patient's temperature to evaluate whether the patient will reach the target patient temperature without reversing the step change, and/or how long it will likely take for the patient to reach the target patient temperature without reversing the step change. The controller then determines whether to reverse the step change or to switch to another algorithm for controlling the fluid temperature.

Systems and methods for temperature-contrast therapy

In one example embodiment, a system for stimulating tissue with the application of temperature-regulated fluid and negative pressure comprises a negative-pressure source adapted to provide negative pressure to a dressing. The system may further comprise a thermoelectric module thermally coupled to a first heat exchange chamber and a second heat exchange chamber and adapted to transfer heat between said heat exchange chambers. The thermoelectric module can be further adapted to maintain a temperature-regulated fluid fluidly coupled to the first heat exchange chamber and the dressing within a predetermined temperature range by adding heat to and extracting heat from the temperature-regulated fluid as it passes through the first heat exchange chamber.

Two-point and multiple-point spot heating and cooling

Apparatus and methods for producing thermal comfort using two point or multipoint heating or cooling that is applied to portion of a human body part to produce a warm or cool sensation over a larger area than that where the heating or cooling is directly applied. The body is induced to heat or cool itself by adjusting its neutral temperature setpoints. Increased warming perception from two-point, multipoint, and switching point stimulation causes downward adaptation in the neutral skin temperature of the user. Because spot heating and cooling sources operate at higher temperature differences from the skin than do area sources, they create a stronger perceived thermal sensation for the same power consumption. Point heating or cooling, rather than whole-area heating, can result in power savings and cost savings while improving occupant comfort.
