INJECTION DEVICE WITH CASE FOR NEEDLE, INTENDED FOR REDUCTION OF SKIN SENSITIVITY Russian patent published in 2016 - IPC A61M5/42 A61M5/32 A61M5/24 

FIELD: medicine.

SUBSTANCE: injection device contains needle case. Said needle case has distal end, capable of connecting with possibility of disconnection with source of injected flowing medium and proximal end for contact with patient. Needle case contains hollow needle, through which injected flowing medium can be delivered to patient, with needle having proximal end for introduction into patient's body tissue, as well as chamber, which has open proximal end. Chamber surrounds, at least, part of needle ad extends proximally beyond proximal needle end to open proximal end. Open proximal end of chamber is made with possibility of deforming and movement with respect to needle from position, in which chamber extends proximally beyond proximal needle end, into position, in which proximal needle end extends proximally through open proximal end of chamber. Open proximal end is made with possibility to create resilient compaction with respect to patient's body tissue to the extent, that allows the chamber, when using, at least partly to be filled with injectable fluid.

EFFECT: inventions make it possible to reduce pain and discomfort, caused by injection.
