| 摘要 |
Device for puncturing a membrane of a human or animal body so as to introduce a liquid formulation thereinto, provided with a patch (10) made of a polymeric material, comprising a base surface (12) having a distal side and a proximal side, and a plurality of projections (11), each projection projecting from the distal side of the base surface to end in a tip (13) arranged for puncturing the membrane. Each projection (11) comprises a cavity (14) and a shell (111) enveloping the cavity at the distal side. The cavity is open towards the proximal side of the base surface. The shells (111) have substantially constant thicknesses. The projections (11) comprise fluid channels (150) emanating from the cavities (14), running through the shells to end at orifices (15) provided in the shells, offset from the tips (13), the fluid channels being oriented obliquely relative to the proximal-distal axis (16, 160). A method for manufacturing the patch is also disclosed. |
