The blood extraction machine has an extraction port and valve. The port defines a chamber into which open two passages and an opening which can be selectively closed by a needle and which is connectable with one of the passages. The extraction port (4) and the valve (5) can be spatially fixed and a movable part of the valve (15) can selective cover the closure in at least one position of the valve and allow access in another position. The movable part of the valve, which covers or releases the closure, can be a grip (26,54) for the valve. |
