The invention relates to medical healthcare equipment, in particular to a wearable multi-field radiation whole-body hyperthermia device. Heat is introduced into a radiating target (i.e., a great vessel) by means of probe beams, and the energy of ultrasound, infrared, laser, microwave, radio frequency and electromagnetic probes at each frequency range is introduced into a vascular circulation system through the radiation probe network composed of probe beams distributed on an attachment in the form of optimum biological heat absorption, and then heat is transferred throughout the body through a hemoperfusion method, so that the vivo tissue is rapidly heated through conduction of biological heat in the tissue. The device has the characteristics of high thermal utilization ratio, high blood flow rate and high specific heat, and thermal convection is rapidly conducted between the radiant heat and the tissue to realize whole-body hyperthermia, therefore, the device not only can realize the purposes of uniformity of the machine body and rapid temperature rise, but also avoid the phenomenon of local overheating, simultaneously, has the accessibility of a wearable device and is a high-efficiency hyperthermia equipment without ache.

The invention is a next generation miniature heart assist device developed in order to maintain the blood circulation in patients with severe heart failure, and is applied endovascularly to the large arteries. This device is technically a kind of synchronous servo electric motor using “direct drive technology”. It provides longer battery life and high blood flow. Small volume and very low energy consumption provide a much longer battery life and a high blood flow. As the outer surface of the parts placed into the blood vessel will be completely covered with the endothelial cells and the intima layer of the arteries in time, there will be no foreign surface contacting directly with blood. As a result, no thromboembolic event or any negative effect on the cellular components of blood is expected.

A chitosan biomaterial is frozen in aqueous solution to form a frozen chitosan structure from which water is removed by a prescribed freeze-drying process to form a sponge-like chitosan structure having a thickness and a density. The sponge-like chitosan structure is compressed by application of heat and pressure to reduce the thickness and increase the density of the sponge-like chitosan structure to form a densified chitosan structure. The densified chitosan structure is further preconditioned by heating the densified chitopsan structure according to prescribed conditions to form a wound dressing. The wound dressing possesses an adhesion strength and resistance to dissolution in high blood flow bleeding situations.

The invention can selectively heat a diseased area or undesired tissue in the body while minimizing heating to the healthy area and surrounding tissue. This is done by exposing the undesired tissue to a scanning focused microwave beam arriving from different directions, all directions passing through the undesired tissue. The invention is particularly useful for heating tissues in which the undesired tissue has reduced blood flow. The undesired area will heat up rapidly while the healthy tissue will be cooled by the blood flow. This is particularly effective for treating emphysema because of the low mass of the lungs and the high blood flow.

A body tissue treatment system comprising a heating device and a topical cream comprises controlled, non-burning heat exhibiting greater temperature fluctuation than a conventional heating device. At high temperature settings, the heating elements fluctuate widely between a relatively high maximum and low minimum to produce periods of intense heat input into the skin followed by sufficient cooling to prevent burning of the skin. Such application of intense heat to the skin, for short periods in which temperatures reach their peaks, relaxes musculature surrounding the injured area and significantly improves blood flow, skin permeability, and sweat gland openness in the area, which allows the topical cream to more readily penetrate skin and / or injured body tissues. While the skin temperature rises and falls to some extent in response to the heating device, the intense heating periods are believed to cause such high blood flow and consequent heat transfer away from the skin surface that the skin temperature does not rise to the extent of being damaged or burned.

The invention relates to a method for determining the recirculation in a fistula and / or the cardiopulmonary recirculation part during an extracorporeal blood treatment, according to which the blood to be treated flows in an extracorporeal blood circuit (I) through a blood chamber (8) of a dialyser (6) split by a semi-permeable membrane (7) into the blood chamber and a dialysis liquid chamber (9), and dialysis liquid flows in a dialysis liquid path (II) through the dialysis liquid chamber of the dialyser. The invention also relates to a device for determining the recirculation in a fistula and / or the cardiopulmonary recirculation part, and to a blood treatment device comprising a device for determining the fistula recirculation and / or the cardiopulmonary recirculation part. The method and device according to the invention are based on the fact that the sum of the fistula recirculation (RA) and the cardiopulmonary recirculation part (RCP), i.e. the total recirculation (R), is determined for two blood flow rates which differ from each other. The fistula recirculation and / or the cardiopulmonary recirculation part are then determined from the recirculation for the two blood flow rates. The first recirculation measurement is carried out for a high blood flow (QBH) for which a fistula recirculation can occur, while the second measurement is carried out for a low blood flow (QBL) for which a fistula recirculation does not occur. These two measuring values form the basis of the determination of the fistula recirculation and / or the cardiopulmonary recirculation part.
