    摘要： The present invention concerns a medical pump comprising: a. A hard housing comprising a top (24) and bottom (1) hard shells, within which a rigid wall (3) and a movable membrane (2) create three distinct chambers; wherein i. said movable membrane tightly separates said second (29) and third (22) chambers ii. said first and third chambers have a watertight interface iii. said second chamber (29) is designed to contain a fluid iv. said first chamber (23) comprises a first venting mean (20) which is arranged to provide a fluidic communication between said first chamber (23) and the external environment; v. said third chamber (22) comprises a second venting mean which is arranged to provide a fluidic communication between said third chamber (22) and the external environment b. A pumping element (4) located in the first chamber (23) c. A least one pressure sensor which measure the pressure gradient between the first chamber (23) and the second chamber (29) d. A fluid pathway which permits: i. a first fluid connection (27) between said second chamber (29) and said pumping element ii. a second fluid connection (28) between said pumping element and a patient line (30).

    摘要： A device for inserting at least one hollow needle for the injection or withdrawal of a solution into/from a tissue, said device comprising a casing (1), a plunger (2) movably mounted inside the casing, and propulsion means (3 and 4) suitable for driving the plunger towards the distal end (1a) of the device by applying a force F1(t). The propulsion means and/or the plunger comprise retaining means (3a) for joining the propulsion means and the plunger while the latter is moving, said retaining means releasing the plunger from the propulsion means when a force F2(t) is exerted in the opposite direction to F1(t). Pressure means hold the needle in the tissue and allow a controlled withdrawal of the plunger at least while the solution is being injected.
