Embodiment Construction

[0022] All variants have filter cartridge 13 as a common element, or sample collection unit (see figure 1 or image 3 Integral assembly of the syringe 11) or a separate part, which is inserted into the sample collection unit by the user (see Figure 4 to Figure 7 The lancing device 12). The filter cartridge 13 comprises a filter unit 10 with a multi-layer filter and a plasma collection container 17 with a conical tip extending towards the filter unit 10 (plasma tip). After plasma extraction, the filter cartridge 13 may be split or separated along the plane ε, resulting in the plasma applicator 14 containing the plasma collection container 17 and the filter housing 8 containing the filter unit 10 .

[0023] exist Figure 1 to Figure 3 The first variant shown in has a filter cartridge 13 integrated in a syringe 11 with a Luer cone 22 formed on the filter housing 8 into which a needle can be inserted. used to collect whole blood samples. In the housing of the syringe 11, a ...

Abstract

The invention relates to a multi-component device for separating plasma from whole blood with a sample collection unit (11; 12) for receiving whole blood; a filter unit (10) with layered filtration with multiple layers a device for extracting plasma; and a pumping unit, preferably a plunger pump (20), for generating a partial vacuum within said filter unit (10). According to the invention, said filter unit (10) and a plasma collection container (17) with a conical tip extending towards said filter unit (10) are contained in a filter cartridge (13), which in plasma After extraction it may be separated, thereby exposing the conical tip (9) of the plasma collection container (17) for sample input into an analyzer.

Description

technical field [0001] The invention relates to a multi-component device for separating plasma from whole blood, with a sample collection unit for receiving whole blood; a filter unit with a layered filter of multiple layers for extracting plasma; and a pumping unit, A plunger pump is preferred for creating a partial vacuum in the filter unit. The invention further relates to a filter cartridge with a multilayer filter unit for separating plasma from whole blood. Background technique [0002] For the separation of plasma from whole blood, in addition to the centrifuges mainly used in laboratories, a large number of devices are known for obtaining very small amounts of plasma by separating plasma from whole blood by means of filtration at point-of-care (PoC). [0003] In the simplest case, plasma separation can be achieved by means of a multilayer test strip as described in DE 40 15 589 Al (BOEHRINGERMANNHEIM), where a transmission layer on an inert carrier layer is provided...
