Improvement of intra-venous (I.V.) catheters used for the subcutaneous administration of liquids or drugs comprising a introducer-needle (2) guiding a cannula or catheter made of flexible material, wherein said 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 said 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.

L'invention porte sur l'amélioration de cathéters intraveineux pour perfusions sous-cutanées de liquides et/ou de médicaments comprenant: une aiguille d'introduction (2) assurant le guidage d'une canule ou du cathéter constitués d'un matériau souple, ainsi qu'en plus du trou d'éjection frontal, plusieurs trous additionnels (8) parsemant les surfaces latérales du cathéter. On obtient ainsi une diffusion homogène et continue du liquide perfusé et sur une surface plus étendue de l'hypoderme, qui évite la formation de pomphus.
