摘要： In a closed system for collecting and retransfusing autologous blood having a collecting vessel (4) to receive the blood and an anticoagulant fluid, as well as a retransfusion line (14, 14') containing a microfilter, through which at least a portion of the blood collected in the collecting vessel (4) is retransfused, the inlet for the anticoagulant fluid is provided, preferably between the collecting vessel (4) in which a negative pressure can be maintained and a drain (2) or the open end of a drain tube. The collecting vessel (4) is connected with a collecting and separating container (13, 13') by means of a tube line (10, 10'), to which a tube pump (11) can be applied. The retransfusion line (14, 14') for the erythrocyte concentrate deposited in the collecting and separating container (13, 13') is connected to the outlet thereof.

摘要： The present invention relates to a method and apparatus for aspiration of secreted fluids from a wound by means of a drain that is connected with a container by a tube, in which the container is a negative pressure, which decreases with the flow of secreted fluid, and regenerates from time to time to a selectable value. A closed system formed by the drain, the container and the tube connecting the two is supplemented for this purpose with a collection container and a second tube that connects the collection container with the container. The second tube has at least one section to which a tube pump can be applied. A clamp is provided in the line formed by the second tube between the container and the collection container.

摘要： A method provided for aspirating secreted fluids from a wound by means of a drain connected to a negative pressure source with variable negative pressure, the negative pressure effective at the drain being adjusted in accordance with a selectable pressure/time diagram. Also disclosed is an apparatus for carrying out the aforementioned method consisting of a negative pressure measuring device and a regulator controlling the negative pressure source, which regulator has inputs for the actual value determined by the negative pressure measuring device and for the prescribed set point value of the negative pressure.
摘要翻译： 一种用于通过连接到具有可变负压的负压源的漏极从伤口吸出分泌的流体的方法，根据可选择的压力/时间图来调节在排水管处有效的负压。 还公开了一种用于执行上述方法的装置，其包括负压测量装置和控制负压源的调节器，该调节器具有由负压测量装置确定的实际值的输入，并且对于规定的设定值 负压。
