FIELD: medicine.

SUBSTANCE: invention relates to medicine and namely to the field of intermittent catheterization and facilitating urinary retention. The complete urinary catheter consists of an outer packaging of gas impermeable material and a temporary urinary catheter containing a hydrophilic coating located inside the outer packaging. The catheter has a proximal end for insertion, a distal end for connection, and a connector at the distal end for connection. The connector forms a distal opening. The assembled catheter also includes a sleeve of liquid impermeable material configured to form at least a portion of a liquid impermeable shell. A liquid impermeable shell surrounds the insertion portion of the catheter. The liquid impermeable shell is closed by the first closure at the proximal end for insertion and the second closure at the distal end for connection. The second closure element is configured to open when the outer packaging is opened, and the first closure element is configured to open when the catheter and sleeve are removed from the outer packaging. The sleeve is attached to the handle at the proximal end. The sleeve is attached to a connector at the distal end. The handle is configured to provide gripping of the catheter at the proximal end without contact with the sleeve. The handle forms a proximal opening. The first cover includes a proximal film and a peelable weld. The peelable weld is located between the proximal foil and the proximal opening of the handle.

EFFECT: invention can be easily introduced into the urethra.
