An intra-venous (I.V.) catheter used for the subcutaneous administration of liquids or drugs includes an introducer-needle ( 2 ) guiding a cannula or catheter made of flexible material. The catheter ( 6 ) has, in addition to the ejection-hole ( 16 ) at the distal end, several additional holes ( 8 ), placed all over the lateral surface of the catheter. This enables to obtain a homogeneous and continuous diffusion of the infused liquid on a larger area of the patient's subcutis, avoiding formation of pomphus.
