Closed, one-handed blood sampling system

A blood sample pond of one-handed operation (80), a pouring into a pipeline (74 and 82), a pipeline with a wind so the liquid to be is cut the reservoir, two opposite to the patient body with. By a wire and an to that are crossed through an closed set (180, 274, 126 and 180) is in reservoir (80) on the two finger-shaped a clamp body. The storage can be a bracket (87); the support of a one-handed operation as to the form or the column is. The reservoir and shape clamp body also be of non-transparent with the inner (322) (306) shell on the bracket and telescopic. The reservoir is located on form a cavity (102) injector shell and a piston and a piston (104); the module is a reciprocating motion to change the cavity volume of the shell. Wherein a bottom of the inlet and outlet electromagnetic intrinsic piston of form a notch (G) to by a constant smallest the volume of the cavity. Is located at the fixed on the belt pressure sensor (90) inlet a pipeline, to with the piston of a spring (110 and 114) capable of changing to the power response liquid pressure system.
