FIELD: medicine.SUBSTANCE: invention relates to medical equipment and in general deals with devices which can be introduced into live body and fixed in it. Device for liquid introduction includes case, cannula, needle guide and partition. Case has case pass-through canal, upper part, bottom surface, first perimetre in upper part and second perimetre close to bottom surface, with first perimetre located in first plane, which is perpendicular to axis parallel to part of pass-through case canal, and second perimetre, located in second plane, parallel to first plane. Second perimetre is longer than first perimetre. Cannula has cannula pass-through canal and part, projecting from bottom surface. Needle guide has part, located inside cannula pass-through canal. Partition has part, located inside needle guide, and has middle part in close contact with surrounding part of device for liquid introduction. Device for liquid introduction is made with configuration for adhesion to live body skin. In the second version of device implementation partition has the greatest width and the greatest length, with the greatest width larger than the greatest length. In the third version of device implementation partition is sunk below upper case part and has bottom surface of partition and part, located inside needle guide, with location of bottom surface of partition, the most distant from upper case part, closer to upper case part than to bottom surface of case. In the fourth version of implementation device includes cannula, which has part projecting from case, cannula pass-through canal and cone-shaped part, needle guide, which has part in contact with cone-shaped cannula part; and partition, which has part, located inside needle guide. In the fifth version of device cannula has cannula pass-through canal and part, projecting from case, with such location of cannula, that any part of cannula, which is outside live body skin in implementation of device for liquid introduction is located
