INTERFACE BETWEEN NOZZLE AND SLEEVE FOR DEVICE DESIGNED FOR INTRADERMAL INJECTIONS Russian patent published in 2022 - IPC A61M5/34 

FIELD: medical equipment.

SUBSTANCE: invention relates to medical equipment, namely to injection devices. The injection device includes a syringe containing a cylinder with a distal end and a proximal end, as well as an end made on the distal end of the cylinder. In this case the cylinder forms an internal channel extending from the proximal end to the distal end of the cylinder. The device also includes a Luer lock adapter containing a case with a proximal end and a distal end, a reduced diameter section created on the proximal end of the case, as well as thread provided on the outer surface of the case. At the same time, the reduced diameter section forms a hole for receiving the end of the syringe by friction fit. The device also includes a needle sleeve containing a case forming an inner cavity, a needle reception section extending distally from this body and a skirt extending inward inside the inner cavity. In this case, the outer surface of the case contains thread corresponding to the thread of the Luer lock adapter to connect the Luer lock adapter to the needle sleeve, while the needle reception section forms a channel to receive the syringe end.

EFFECT: obtaining a device for intradermal injections.
