1. A method for filling, with a liquid medium, an analysis card comprising a body in which at least one reading cavity is formed, an orifice communicating with said cavity via at least one internal channel, an external conduit having one end in communication with said orifice and a free end, and a means for closing and opening the external conduit, wherein gas contained in the card is evacuated via said external conduit and the liquid medium is introduced into the evacuated card by immersion of the free end of said external conduit in the liquid medium, said method comprising, in succession: to evacuate the gas contained in the analysis card, connecting the free end of the open external conduit in a leaktight manner directly to an evacuation means, outside the liquid medium; closing the external conduit in order to maintain negative pressure in the analysis card; immersing the free end of the closed external conduit in the liquid medium; and opening the external conduit, after immersion of said free end, in order to aspirate the liquid medium into the analysis card. 2. The method of claim 1, wherein the means for closing and opening the external conduit is a pinching means. 3. The method of claim 1, wherein the means for closing and opening the external conduit is a screw. 4. The method of claim 1, wherein the means for closing and opening the external conduit is a valve. 5. The method of claim 1, wherein the liquid medium is contained in a receptacle, said method comprising, in succession: connecting said free end of said open external conduit to the evacuation means outside the receptacle, immersing said free end of said closed external conduit in the liquid medium in said receptacle, and opening the external conduit, while maintaining said free end immersed in said receptacle. 6. The method of claim 1, wherein the external conduit is a flexible conduit, wherein closing the conduit is obtained by pinching said conduit, and opening the conduit is obtained by releasing said pinching. 7. The method of claim 1, wherein the evacuation means is a pump. 8. The method of claim 1, wherein the evacuation means is a manual pump. 9. The method of claim 1, wherein the evacuation means is a reciprocating pump. 10. The method of claim 1, wherein the evacuation means is a reciprocating manual pump.
