FIELD: physics.
SUBSTANCE: enveloped interfacing module (20) has a hollow needle (23) and a bushing (22) in which a first section of the needle (23) is rigidly built into a first section (22a) of the bushing. The needle (23) has a free end which is partially surrounded with an intermediate gap by a second section (22b) of the bushing, and which can bend in the radial direction, wherein radial displacement of the needle (23) is limited by the second section (22b) of the bushing (22) to the elastic deformation range of the needle. Also, the vertex of the free end of the needle (23) is blunt. The enveloped interfacing module (20) also has a tubular connector (24) which is linked through the fluid medium with the inner space of the needle (23).
EFFECT: low risk of damaging the needle.
