DEVICES, SYSTEMS AND METHODS OF LIQUID INTRODUCTION Russian patent published in 2012 - IPC A61M39/04 A61M1/00 

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 inside external case perimetre. In addition, device is made with such configuration that injection needle, which passed through partition for introduction of medication into live body during application of device for liquid introduction either (a) goes from partition into open space, which is located inside pass-through case canal and lower on course of, at least, part of partition bottom surface, or (b) contacts with part of device for liquid introduction, which is cone-shaped inwards. In the sixth version of implementation device contains partition, sunk below upper case part, which has bottom surface of partition and part, located inside pass-through canal of needle guide, with location of bottom surface of partition, the most distant from upper case part, closer to upper case part than to bottom case part. The third version of device implementation represents variation of previous implementations. In the eighth version of device implementation bottom surface of partition is made with such configuration and partition is located in such a way that, if injection needle, which passed through partition for introduction of medication into alive body during application of device for liquid introduction goes out from bottom surface of partition into open space, open space is located inside case pass-through canal and below on the course of, at least, part of partition bottom surface. The ninth version of device implementation represents variation of previous implementations.

EFFECT: simplification of introduction of liquid such as medication into live body.
