Abstract: A heating device for a medical instrument is disclosed. The heating device includes a heating wire. The heating wire is of a metal alloy that has in the temperature range between 0° C. and 100° C. a temperature-sensitive electrical resistance gradient of at least 0.004 ?/(m*K).

Abstract: A blood warmer (10) has a first heating plate (12) and a second heating plate (14) as well as an exchangeable conductor (18, 20, 22, 24) for blood, which is arranged between the first heating plate (12) and the second heating plate (14). The blood warmer (10) has an inlet (66) and an outlet (68) for blood to which the conductor (18, 20, 22, 24) is fluidically connected. Due to the roughness of the surface (46) of the conductor (18, 20, 22, 24), an intermediate space (50) remains between the first heating plate (12) and/or the second heating plate (14) and the conductor (18, 20, 22, 24). A medium (52), which has a higher thermal conductivity than air, is at least partially statically arranged in the intermediate space (50). The blood warmer (10) may also have an electromechanical oscillating circuit and/or a vibration motor.

Abstract: A fluid warmer (10) for temperature control of a medical fluid (14) guided in a fluid tube (12) and a method for operation thereof have a sensor (38), which determines a leakage current (40) via a functional grounding conductor (FE). Two supply connection conductors (22a; 22b) for a resistance heating element (18) as well as the functional grounding conductor (FE) are each equipped with a switch (30a; 30b; 30c) which can be controlled by a control device (32). The switches (30a; 30b; 30c) can be put into their open switching state jointly within a defined time interval by means of a control device (32) on occurrence of a leakage current (40) that is greater than or equal to a defined maximum threshold current magnitude (ITon, IToff).

Abstract: The invention is a small container for storing and discharging liquid and/or pasty materials. The container has a cylindrical tank with a cleaning portal mounted in the top-most portion thereof, and a base further comprising a discharge hopper. The base is configured with a wedge shape and is manufactured from material capable of being deep-drawn. The base is produced in one piece with the discharge hopper. The discharge hopper is shaped jointly with the base by means of a cupping procedure and is sloped at an angle of approximately 12°. An upper area of the base is molded with a first stroke of the cupping procedure and the drainage hopper, as an eccentric drainage cup, is molded with a second stroke. The container can have a stacking support assembly mounted on an upper portion of the container, and a stacking acceptance assembly mounted on a lower portion of the container.

Abstract: A liquid heating bag 50 is proposed, in particular, a blood heating bag, with a flow volume 1 that is formed from at least two flexible plastic foils connected to each other by welding at four delimiting edges 3,4,5,6, has a flat, substantially trapezoidal basic shape that is limited by the delimiting edges 3,4,5,6, and an inlet line opening 10 and an outlet line opening 11 for a liquid to be heated that are disposed at an upper delimiting edge 3 of the delimiting edges 3,4,5,6 to be disposed at the top during liquid heating, wherein the upper delimiting edge 3 extends sufficiently obliquely with respect to its adjacent delimiting edges 4,6 that a gas reception volume 8 is formed in the region of an acute angle of the flow volume 1 subtended between the upper delimiting edge 3 and a delimiting edge 6 adjacent thereto, and a liquid flow guiding seam 13 that is formed by connecting the plastic foils in the region of the flow volume 1 and divides the upper delimiting edge 3 into a lower inlet line opening region
