Abstract

The present invention relates to device for quantitative and/or qualitative determination of the presence/absence of a substance in a body liquid comprising a rotatably arranged magazine containing a number of test electrodes intended to be brought into contact with a body liquid to be determined, an arm arranged to influence a test electrode to move in relation to said magazine, whereby the arm comprises contact sheet metals arranged to releasably be fixed to said test electrode and arranged to return said test electrode to the magazine after a finished testing, as well as an arm contained in said device.

Claims (7)

1. Device for quantitative and/or qualitative determination of the presence/absence of a substance in a body liquid comprising a rotatably arranged magazine containing a number of test electrodes intended to be brought into contact with a body liquid to be determined, an arm arranged to influence a test electrode to a relative movement relative to said magazine, characterized in that the arm (13) comprises contact sheet metals (14) arranged to releasably be fixed to said test electrode (4) and arranged to return said test electrode (4) to the magazine (3) after a finished testing.
2. Device according to claim 1, characterized in that the arm (13) with its contact sheet metals (14) is arranged to be brought into contact with a test electrode (4), whereby the arm (13) is arranged to grip said test electrode (4).
3. Device according to claim 2, characterized in that the arm (13) at its front end is provided with flexible gripping claws (10) placed on either side of said contact sheet metals (14) and arranged to be able to be compressed around a contact end of a test electrode (4) to grip the test electrode (4).
4. Magazine containing test electrodes placed in individual spaces for the determination of absence/presence of a substance in a body liquid, characterized in that the spaces (15) receiving the test electrodes (4) are inwardly tapering in such a way that an arm (13) with its contact sheet metals (14) introduced in such a space is brought to releasably grip and keep the test electrode (4) so that this is released from said arm (13) when being returned into said space.
5. Magazine according to claim 4, characterized in that the magazine (3) contains at least six spaces (15) for test electrodes (4).
6. Magazine according to claim 5, characterized in that the magazine (3) contains at least eight spaces (15) for test electrodes (4).
7. Arm for receiving a test electrode intended to be used in a device according to claims 1-3, characterized in that the arm (13) comprises a front end provided with a test electrode receiving unit (20) containing contact sheet metals (14)and flexible gripping claws (10) placed on each sides of said contact members at its forward end and arranged to be able to be compressed around a contact end of a test electrode to grip and retain a test electrode (4).
