Definitions
- the invention relates to the filling with a liquid medium of an analysis card.
- analysis card means any means for single use, or not, making it possible to carry out one or more simultaneous analyzes, from a single sample and from one or more reagents, and this in a manner impervious to the external environment, the result of the analysis or analyzes being obtained for example by optical means.
- an analysis card comprises a body in which is formed at least one reading cavity, receiving during use all or a portion of the sample with at least one reagent preexisting in said cavity , and an orifice communicating with said cavity by at least one internal channel.
- This or these cavities therefore communicate with the outside only through the aforementioned orifice, while the card is generally associated or cooperates with an external, flexible conduit, communicating in leaktight manner with this orifice. It is this external conduit which makes it possible to take, as described below, the sample from the liquid medium to be analyzed.
- liquid medium any product or liquid body, in any case liable to flow by pumping, whatever the viscosity or fluidity of this liquid; in particular, being a biological analysis, the term “liquid medium” means a medium comprising, for example, one or more microorganisms or a biological product to be analyzed.
- a sealed box with means for controlling the internal pressure, and in particular the vacuum when said box has been placed under vacuum;
- a container for example a test tube, in which the liquid medium to be sampled or taken is placed, and on the other hand next to the container, the analysis card with the free end of the external conduit, immersed in the liquid medium contained by the container;
- the air from the box is evacuated to a significant vacuum level, for example less than 100 mbar absolute, whereby the air from the analysis card is evacuated, and the evacuated air passes through the liquid medium of the container;
- the subject of the present invention is a method of filling an analysis card, non-contaminating, in that it always works under vacuum, that is to say without the possibility of evacuating the liquid medium to the outside. manipulated.
- the free end of the open external conduit is connected directly, in a leaktight manner, with an evacuation means, and this outside of the liquid medium handled;
- the present invention also provides the decisive advantage that pumping the gas contained in the analysis card requires limited work, and therefore becomes compatible with relatively simple, even rudimentary, in particular manual pumping means.
- the filling method described above can be used both manually and within an analysis automaton.
- FIG. 1 shows in perspective and schematically, an analysis card as considered by the present invention
- FIG. 2 shows schematically a filling device according to the invention
- FIG. 3 shows in perspective an embodiment of the device shown schematically in Figure 2;
- FIG. 4 represents a sectional view of the connection means and of the closure means forming part of the device shown in FIG. 3.
- An analysis card 2 processed by the filling method according to the invention, with the device shown in Figures 2 and 3, comprises: - A body 3, of plastic, molded, of generally flat and rectangular shape, in which are formed on the one hand several series of reading cavities 3a, and on the other hand internal open channels 7, as well as an orifice 4; two sheets 10 of transparent plastic material, sealed in a sealed manner respectively on the two faces of the body 3;
- an external conduit 9 flexible, in the form of a bent straw, tightly assembled with the body 3, at the time of use of the analysis card, comprising a free end 9a, and an opposite end communicating in leaktight fashion, after assembly or assembly, with the orifice 4.
- a distributor duct 5 communicates on one side with the orifice 4, and on the other side with a series of ramifications 6, on each of which the different reading cavities 3a are connected by respective internal channels 7.
- a filling device comprises:
- a frame 18 comprising a base 19 and a vertical wall comprising two sides 20a and 20b at right angles;
- Evacuation means 50 consisting of an alternative manual pump, mounted on the side 20b, actuated by a lever 44, which can be locked in rotation by a ratchet mechanism 26 controlled by an arm 25;
- a connection means 11, more particularly shown in Figure 4 comprising on one side an end piece 12 for sealing and removable coupling with the free end 9a of the external conduit 9, thanks to an O-ring 14, clamped between said end piece and a counter end piece 13, the latter communicating directly on the other side with the discharge means 50;
- the analysis card 2 to be filled is placed in the carriage 21, and the closure means 34 is left open; - The carriages 21 and 24 are moved by means of displacement means 17, so that the free end 9a of the external conduit 9 communicates in leaktight manner with the connection means 11 (confer representation of FIG. 4); - by actuating the lever 44, the gas contained in the analysis card 2 is discharged, in this case atmospheric air, and the discharge pressure is checked by means of the pressure gauge 27; this may require one or more back and forth movements in rotation of the lever 44, depending on the displacement of the discharge means 50; once the level desired vacuum achieved, the lever is fixed in position by means of the ratchet mechanism 26;
- the external conduit 9 is reopened, after immersion of this free end, while keeping the end 9a immersed, which causes the suction of the liquid medium 1 in the analysis card, until each of the reading cavities 3a is filled ;
- the analysis card is filled and is ready to undergo the required analysis process, with reading of the results through the different reading cavities 3a.
