Self-heating apparatus and methodology for customizing a time-temperature profile thereof. The layered apparatus includes at least a layer of phase change material and a layer of air- or oxygen-activated material. When the air- or oxygen-activated material is activated, heat is released rapidly and is absorbed by the phase change material. The phase change material then releases the absorbed heat over a long period of time. Time-temperature profiles can be adjusted based on type, amount, and configuration of phase change and air-activated materials used. The apparatus and methodology allows rapid heat-up of times of a few minutes and lasts several hours at near constant tunable temperatures.

A portable moxibustion therapy device includes a main body 20, having a top opening 21, a sidewall 22 and a bottom 23, and the sidewall 22 comprises a plurality of holes 24 on the sidewall 22 of the main body 20; a cover 30 for opening and closing the top opening 21 of the main body 20; a moxa container 40 which is substantially cylindrical and made of yellow soil in the main body 20; a cylindrical support 50 made of yellow soil placed the moxa container 40 blow in the main body 20; and a gauze 60 located between the moxa container 40 and the cylindrical support 50 in the main body 20. The portable moxibustion therapy device includes a plurality of holes to supply air or oxygen to the moxa 90.

An Ultrasound Transmission Gel Packet Having Internal Heat Source and Method of Use. The gel packet is sized for a single use, rather than for multiple applications. The gel packets are not pre-heated, but rather are quickly heatable on demand. The gel packets may incorporate a variety of optional internal heating methods, including chemical activation, mechanical agitation and electrical activation, among others. The gel packets are sealed and therefore have extended shelf lives, and further are disposable after use.

A biopsy device having an elongate biopsy needle and a thermal cooling device. The biopsy device includes an elongate biopsy needle that has a proximal end portion, an intermediate portion, and a distal end portion. The elongate biopsy needle is made of a thermally conductive material. The biopsy device includes a thermally conductive mechanical member that extends between the proximal end portion of the elongate biopsy needle and the thermal cooling device. The thermally conductive mechanical member has a first end and a second end. The biopsy device includes a first thermo-mechanical coupler that connects the first end of the thermally conductive mechanical member to the thermal cooling device and a second thermo-mechanical coupler that connects the second end of the thermally conductive mechanical member to the proximal end portion of the elongate biopsy needle.

A portable system for cold therapy with optional heat and compression therapy is disclosed, including a cooling mechanism, a reservoir, and a control assembly. The cooling mechanism includes a compressor, a condenser, a fan, and a heat exchanger. The compressor has an air inlet connected to the heat exchanger through a first tube. The heat exchanger is connected to the condenser through a second tube. The condenser is connected to an air outlet of the compressor through a third tube. The first tube and the second tube are connected by fluid, and the second tube and the third tube are connected by fluid. The fan has a working surface facing the condenser. The liquid in the reservoir flows into the heat exchanger and then flows into the first body wrap, and then can flow into the heat exchanger or flow back into the reservoir.
