CONNECTION STRUCTURE FOR THE SYRINGE NEEDLE BASE AND SYRINGE BODY IN A SAFE SYRINGE Russian patent published in 2018 - IPC A61M5/32 

FIELD: medicine.

SUBSTANCE: invention relates to medical technique, namely to a connecting structure for the base of a syringe needle and a syringe body in a secure syringe. Connecting structure comprises: a front end of the syringe body, on which a connecting tube is provided, which is smaller than the outer diameter of the syringe body; the base of the syringe needle in the form of a column; front end of the syringe needle base used to connect to the syringe needle; elastic connecting elements of the connecting structure located at the rear end of the base of the syringe needle; first connecting parts located on the inner side of the connecting tube; outer sides of the connecting elements on which the second connecting parts are provided; and the inner sides of the connecting elements on which the expansion part is provided. Base of the syringe needle is covered by a connecting tube. In this case, the first connecting portions are projections that protrude beyond the inner side of the connecting tube, and second connecting parts are recesses which are formed on the outside of the connecting elements and correspond to the protrusions. In this case, the extension part rests against the inner sides of the connecting elements, so that the outer sides of the connecting elements expand, in contact with the inner side of the connecting tube. In this case, under the widening effect of the expansion part, the first connecting parts enter into the clamping connection with the second connecting parts.

EFFECT: claimed invention ensures preservation of high stability and simplification of the structure.
