A high-pressure medical cryotherapy device is provided. The device is designed for spraying liquid carbon dioxide onto a patient to alleviate inflammation through a series of treatments via a portable machine. The device features a gun-like body with a quick-connect fitting for liquid CO2 entry, a trigger-operated valve system for CO2 flow control, and a nozzle that can be attached in various ways and adjusted for different spray patterns. Additional components include a flow adjustment knob for regulating CO2 flow rate, a heating element to prevent frosting and ensure smooth CO2 expulsion, thermistors, and temperature sensors for temperature management, and lasers for visual distance referencing.

A temperature-controlled massage node that imparts either or both a heating or cooling effects is provided, which may be attached to a massager to impart a heating or cooling effect on a user with a massage effect, or optionally, without a massage effect. The temperature-controlled massage node may be affixed to the massager or may be removably coupled. The temperature-controlled massage node may be powered by the same power source as the massager or may include an independent power source located, for example, in the massage node. The massage node may be used with a massager that provides percussive massage effects, such as a massage gun, or may be used with a vibrating massager. Optionally, the massage node may include independent power, a controller and a motor to supply both a vibrating massage effect and hot and cold effect, either alone or in combination.

A personal microclimate control system for sensing cutaneous conditions on a body. The sensors are located on spatially distinct physical locations on a body, adjacent to the cutaneous layer. A controller and connected memory stores the addresses for the sensors. The controller operates the sensors based on their addresses for the purpose of improving thermal comfort. In an embodiment, the controller controls the sensors by executing multiple-input multiple output algorithms. Embodiments are further directed to controlling a plurality of individual electronic effectors as well as to improving system safety, usability and management capabilities.

A heating element includes an electrically insulating layer; resistive layer formed of a positive temperature coefficient material; and an electrically conductive layer disposed between the electrically insulating layer and the resistive layer and including a first bus and a second bus that is spaced apart from the first bus, the resistive layer electrically connecting the first bus and the second bus. The electrically insulating layer, the electrically conductive layer, and the resistive layer are stacked to form a lamination and the lamination having a thickness and a width and length extending orthogonal to the thickness. The lamination may have slits extending through the thickness thereof and along a portion of the length thereof. Terminals may be connected to the buses and arranged to provide a counter current flow pattern across the lamination. The lamination may be used in a warming device and in connection with a patient warming system.

An AI thermal and human body detection system using a temperature sensor includes a base unit; a bimetal cutting off power to prevent overheating; the temperature sensor detecting a temperature of a thermal mat; a heating wire disposed in a zigzag shape on the base unit and converting electrical energy into heat energy; and a power supply unit supplying power to each component of the thermal mat.

Disclosed is a thermal contact sensor for use in aesthetic skin by heat treatment for altering the aesthetic appearance of a subject. The thermal contact sensor measures the difference in sensor temperature when in contact or absence of contact with the skin and automatically operates a source of optical radiation to heat the skin.
