摘要： Embodiments of the present disclosure provide a device, an apparatus, and a method for controlling infusion. The device may include a multi-port container assembly and a liquid flow controller. The multi-port container assembly includes a multi-port container having a plurality of inlets and an outlet, a detector configured to detect amount of liquid in the multi-port container, a first communication subassembly, and a first controller. The first controller may send a first signal to the liquid flow controller via the first communication subassembly in response to the detector detecting that the amount of liquid is lower than a first predetermined threshold. The liquid flow controller may turn off a first infusion tube currently used and turn on a next first infusion tube in response to receiving the first signal.

摘要： A warming unit (21) coupled or configured to be coupled to a heated portion (19) of a fluid circuit (6, 7, 10, 11, 13, 14, 15; 107) of a medical device (1, 100). The warming unit (21) comprises a leakage current reduction circuit (35) configured to perform the following procedure: connecting a heat transfer element (22) of the warming unit (21) to a ground connection (33) through a resistance element (34), which keeps a normal condition patient leakage current below a first limit value, and disconnecting the heat transfer element (22) from the ground connection (33) if a current indicating that the patient is connected to the mains voltage is sensed through the resistance element (34), in order to keep a fault condition patient leakage current below a second limit value.

摘要： A fluid warming device has a heat exchange body having an input port and an output port and conducts fluid from the input port to the output port. The fluid warming device has a heater assembly configured to transfer heat to the heat exchange body. The fluid warming device may also have a temperature sensor for measuring a temperature of the heater assembly, and a power sensor for measuring a power to the heater assembly. The fluid warming device also has a controller connected to the temperature sensor and the power sensor. The controller calculates a fluid flow rate and a total volume of fluid delivered through the heat exchange body based on the temperature and the power.

摘要： A syringe propellable by propellant that boils at a predetermined temperature, the syringe including a barrel having an outlet at a front end, and a stopper axially moveable in the barrel. The stopper separates a first chamber and a second chamber, the first chamber being axially forwards of the stopper and being configured for containing a medicament, and the second chamber being axially rearwards of the stopper and being configured to receive propellant for acting on the stopper to move the stopper axially forwardly in the barrel to expel medicament through the outlet upon actuation of the syringe. The syringe further includes a third chamber for containing propellant. Upon actuation of the syringe, liquid propellant is released from the third chamber and boils outside of the third chamber at or above the predetermined temperature to provide an increasing vapor pressure in the second chamber that causes the stopper to move axially forwardly and begin to expel medicament through the outlet. At least one trigger for triggering an action is provided, the trigger activated in response to the pressure in the second chamber satisfying a predetermined condition.

摘要： A system and method for inductive heating applications includes positioning one or more inductive heating elements in a location, delivering electromagnetic radiation, by a radiation source, to heat at least a portion of the one or more inductive heating elements, and detecting, by a detector, the heat generated by the one or more inductive heating elements. The system and method also include controlling, by a processing unit, a condition based on the detected heat.

摘要： Apparatus, system and method for heating fluid from a plurality of fluid sources. A heating chamber top portion includes a plurality of fluid inlet tubes configured to pass fluid from the plurality of fluid sources. A heating chamber may be coupled to the heating chamber top portion, the heating chamber collectively receives at least some of the fluid from the plurality of fluid sources. At least one heating element configured within the heating chamber heats the received fluid from the plurality of fluid sources. An agitator mixes the received fluid from the plurality of fluid sources in the heating chamber, wherein the agitator is configured to mix the received fluid from the plurality of fluid sources by rotationally turning within the heating chamber.

摘要： A new type of syringe for delivering composite material for direct application of the material in the mouth of a patient. The new type of syringe includes a threaded screw for driving a piston through the syringe in order to extrude the material from the end of the syringe. The extrusion force is thus generated in the syringe, thereby allowing for a simpler, less costly motorised driving system using a torque driving movement. The syringe also includes a localised heating arrangement at the extrusion end.

摘要： A weighing system for medical applications may include a basin that has a base and a sloped sidewall that collectively form a bounded cavity with open top surface that receives and holds the material to be weighed. The basin may be free floating above the weighing device within a restricted range of travel. In some examples, the weighing system includes a thermal treatment device to adjust the temperature of the material in the basin. The rate at which heat is delivered to the basin may vary depending on the weight of the contents in the basin.
