SELF-ORIENTED HIGH-PRESSURE CASING AND MECHANISM FOR HIGH PRESSURE CASING AND INJECTOR CONNECTION Russian patent published in 2019 - IPC A61M5/142 

FIELD: medicine.

SUBSTANCE: high-pressure casing comprises: a cylinder having a proximal end, a distal end and a sidewall extending substantially circumferentially between the proximal end and the distal end along the longitudinal axis, said cylinder having an inner surface forming an inner volume is configured to receive a syringe therein with a possibility of limiting radial expansion of the syringe during the injection procedure; and at least one high pressure jacket retaining element, having at least one hook extending radially outwardly relative to the outer surface of the side wall, wherein said at least one hook is chamfered in axial direction along the outer surface of the side wall from the distal end to the proximal end. At that, said at least one hook is made with possibility of engagement with locking mechanism on fluid injector to attach high-pressure casing to fluid injector with possibility of disconnection. Bevel of said at least one hook is configured to direct high-pressure housing when turned into position of self-aligning with locking mechanism and push high pressure housing in axial direction when high pressure jacket is turned.

EFFECT: invention refers to medical equipment, namely to a high-pressure casing.
