A drug delivery pump includes a dosing chamber (16) for delivering a substance (18) therefrom, pushing apparatus, and a thermal energy source (14) arranged to cause a sufficient change in temperature in a portion of the pushing apparatus so that the pushing apparatus imparts a pushing force against the substance to cause the substance to be delivered from the dosing chamber. A controller (90) controls delivery of the substance from the dosing chamber. A thermal insulator (24) thermally insulates the substance in the dosing chamber from the thermal energy source.

The present invention relates to a heating device for one or more components of an extracorporeal circuit of a blood treatment device, in particular of a dialyzer, an adsorber or a filter, wherein the heating device has at least one reception region for the named component and at least one heating element for heating the component located in the receiver, wherein the heating device has a plurality of layers, with at least one layer being a flexible layer or elastically deformable layer.

There is disclosed a fluid warming system (300) for warming intravenous fluid, comprising: a heater unit (304), including a heating element (314) and at least one temperature sensor; a heat exchanger unit (302), removably attachable to the heater unit (304), which includes an inlet (306) and an outlet (308) through which the fluid can pass, and a controller (316), programmed: to receive at least one temperature measurement (T.sub.CI, T.sub.CO) from said at least one temperature sensor in the heater unit (304); to compute a fluid flow rate (q), corresponding to the rate of flow of fluid from the inlet (306) to the outlet (308) of the heat exchanger unit (302), in dependence on the amount of electrical power (P.sub.H) supplied to the heating element and said at least one temperature measurement (T.sub.CI, T.sub.CO); and to control the electrical power (P.sub.H) supplied to the heating element in dependence on the computed fluid flow rate (q).

A cassette for a heated fluid ablation system, comprises a fluid supply lumen receiving an ablation fluid from an external fluid source and a fluid chamber containing a therapeutic agent in combination with an impeller pumping the ablation fluid out of the cassette via to a fluid delivery lumen when the cassette is in a first configuration and pumping the therapeutic agent out of the cassette via the fluid delivery lumen when the cassette is in a second configuration.

An automatic injection device has an insertion needle configured to be inserted into a patient and a drug container which contains a pharmaceutical product and includes a plunger. The automatic injection device also has a fluid path which fluidly connects the drug container to the insertion needle, and a drive system configured to cause linear movement of the plunger to force the pharmaceutical product into the fluid path. The drive system has a movable element. The movable element has a shape memory alloy and is configured to change shape to move the plunger.

A medical drip bag heater includes a flexible sheet of material configured to wrap around a drip bag, heating wires, velcro strips, and a thermostat control. The sheet of material includes a body portion with two side edges and a bottom flap with a bottom edge. The heating wires are embedded into the sheet of material and configured to electrically connect to a power source through a thermostat control. The velcro strips are fixedly attached to the two side edges and the bottom edge. The thermostat control controls the temperature of the heater and displays the temperature.

A dispensing assembly has a dispensing chamber housing, a temperature control device, a thermal sensor, and an interface. The dispensing chamber housing has an inner surface, an outer surface, and a wall thickness. The inner surface partially defines a dispensing chamber for receiving a quantity of a substance. The temperature control device at least partially surrounds the dispensing chamber housing. The temperature control device alters a temperature of a substance in the dispensing chamber. The temperature control device and the thermal sensor are located on a substrate. The substrate is wrapped around an exterior surface of the dispensing chamber housing. The interface is connected to the temperature control device and the thermal sensor. An interface connector is connected to the interface. The distance between the temperature control device and the thermal sensor is approximately equal to the wall thickness of the dispensing chamber housing.
