A method for a thawing device configured to thaw/heat a blood product comprised in a container, the method comprising the steps of performing a massaging motion, by a first actuator, on one or more areas of an outer surface of the container, obtaining measurements, from a reflectance sensor coupled to an antenna, the measurements at least being indicative of phase of received radio frequency, RF, waves having a second frequency and being reflected off the container, determining a third frequency, wherein the third frequency is determined by a predetermined relation dependent on the second frequency and the obtained measurements, controlling a transmitter, communicatively coupled to the antenna, to emit RF waves, using the obtained measurements, wherein the emitted RF waves are emitted at a third frequency and are directed by the antenna to propagate towards the container, wherein the third frequency is in the range of 10 to 900 MHz.

b) configured to detect the position of the object (14) inserted between the electrodes. The welding apparatus further comprises a processor configured to process the input from at least one of the detector (16; 26), the distance sensor (17; 23) and the conductance sensor (24) to provide an output that indicates if there is a blood bag tube inserted between electrodes, or if it is a foreign object.
Welding apparatus (10; 30) having a safety feature comprising: two electrodes (11, 12; 21, 22), whereof at least one of said two electrodes is movably arranged in relation to the other electrode. The electrodes are in non-contact with each other and define a gap (13) in which an object (14) provided with an electrically non-conductive surface to be sealed may be inserted. The welding apparatus comprises an actuator (15; 25) configured to move at least one electrode when activated to squeeze the object, a detector (16; 26) configured to determine a clamping force when the inserted object (14) is squeezed between the electrodes, a distance sensor (17; 23) configured to measure the distance between the electrodes. There is also a conductance sensor (24) configured to measure the conductivity of an object located between the electrodes (11, 12; 21,22) when the object (14) is squeezed, and optionally a position sensor (19b) configured to detect the position of the object (14) inserted between the electrodes. The welding apparatus further comprises a processor configured to process the input from at least one of the detector (16; 26), the distance sensor (17; 23) and the conductance sensor (24) to provide an output that indicates if there is a blood bag tube inserted between electrodes, or if it is a foreign object.
A cartridge holds a perishable dielectric load, e.g. blood plasma, during heating n a heating chamber by means of an electromagnetic field from an emitting element. A conducting container of the cartridge is arranged between the emitting element and the perishable dielectric load. The conducting container holds dielectric matter and is arranged in contact with a load container for the perishable dielectric load, so that energy from the electromagnetic field is bridged into the perishable dielectric load. A first surface of the cartridge faces the emitting element and contains a recess for receiving any fluid having leaked out from the conducting container and/or the load container. A transmitter module for generating the electromagnetic energy repeatedly measures an impedance of the perishable dielectric load and the conducting container. If, due to any fluid being located in the recess, the impedance deviates substantially from a previous measurement, an alarm signal is generated.

A blood mixer comprises a support structure supporting the components of the mixer(10), a tubing fastening and guiding arrangement, configured to secure a blood collecting tubing in the mixer(10), a tray (18) adapted to house a blood collecting bag (16) having a blood tube (14) attached thereto, and configured to measure the weight of the collected blood in the blood collecting bag (16) and a pump (20) configured to draw blood from the donor (12) to a blood collecting bag (16)through said tubing(14). The pump (20) is configured to exert a kneading action on the blood supply tubing (14) by means of at least two kneading elements arranged to alternatingly displace the contents of the tube in the direction towards the bag(16). There is also provided a cooling arrangement (19) configured to cool the blood in the blood collecting bag(16).
This disclosure relates to a cordless, hand held and electrically powered apparatus, comprising a welding unit (12), a power unit (4) for powering the welding unit, wherein the power unit is connectable directly to and disconnectable from the welding unit via an interface. The power unit is provided with a push button (16) that is configured to energize the welding unit when pressed down, thus initiating operation thereof. The advantage is that the apparatus can be made more compact, and thereby ease of handling is improved. Preferably, the welding unit and the power unit each comprise circuitry (17a, 17b) configured to exchange information when mounted together via the interface. The information is usable for a determination whether the power unit is a correct one or not.

This invention is about a method and a device for equalizing warming processes in dielectric loads using electric/electromagnetic fields at frequencies below 900 MHz. Characteristic for the invention is that the load is surrounded by a field equalizing material and that the load and the electric/electromagnetic field is moved relative to each other.
