Problems solved by technology

This will cause air to be drawn from the connected hoses while the hoses collapse and stick to each other
This in turn can impair the ready-to-use and availability of the entire device in the future, because the hose is sometimes permanently deformed
In addition, in the above-mentioned devices, there is no possibility of feeding moist hot steam for steam sterilization into the already assembled system

Embodiment Construction

[0029] The device comprises a filter device 2 which forms an inlet chamber 4 and an outlet chamber 5 by means of filter elements 3 arranged therein. The device 1 further comprises a receiving container 6, which is used to receive blood components composed of cells, separated in the filter device 2, including erythrocytes; and a receiving container 7, which is used for filtering Leukocyte-containing plasma separated in device 2. The inlet chamber 4 of the filter device 2 is connected on the outlet side to the receiving container 6 for the blood component consisting of cells by means of a line 8 formed as a plastic hose and consisting of line sections 8 a and 8 b. The outlet chamber 5 of the filter device 2 is connected on the outlet side by means of a line 9 formed by a plastic hose to the receiving container 7 for blood plasma by way of a line.

[0030] The device 1 further comprises a blood source, generally indicated at 10 , comprising a blood receiving container 11 and a p...

Abstract

The invention relates to a device (1) for separating blood individually and / or in groups of components thereof, in the form of a sterisable system comprising a filter arrangement (2), which forms an inlet chamber (4) and an outlet chamber (5) by means of a filter element (3) which is arranged therein, a receptacle (6) for cellular blood components and a receptacle (7) for blood plasma.The inlet chamber (4) of the filter arrangement (2) can be connected to the blood source (10) via a line on the inlet side and is connected, on the outlet side, to the receptacle (6) for cellular components of the blood. The outlet chamber (5) is connected to the receptacle (7) for blood plasma via a line on the outlet side.; The aim of the invention is use thermal sterilisation, in particular vapour sterilisation, in order to sterilise said device.Said aim is achieved by virtue of the fact that a line (17, 20) is connected to the inlet-sided line (14) of the inlet chamber (4) or to the inlet chamber (4) and to the outlet-sided line (20) of the outlet chamber (5) or to the outlet chamber (5), in order to join towards the environment via a hydrophobic or hydrophilic filter, in particular hydrophobic or hydrophilic bacteria filter (18, 21).

Description

technical field [0001] The invention relates to a device for separating blood into individual blood components and / or grouped blood components in the form of a sterilizable system, comprising: a filter device, which is arranged by means of The filter element forms an inlet chamber and an outlet chamber; a receiving container for blood components composed of cells; The outlet chamber is connected on the outlet side by a line to the receiving container for the blood component composed of cells, and the outlet chamber is connected on the outlet side by a line to the receiving container for the blood plasma. [0002] The invention further relates to a method for steam sterilization of a device in the form of a sterilizable system for separating blood into individual blood components and / or into grouped blood components, which device comprises a filter device , a receiving container for blood components composed of cells and a receiving container for plasma, the filter device form...
