FIELD: medicine. ^ SUBSTANCE: invention relates to medical equipment and urology. Permanent catheter for draining urea from urinary bladder into urinary sphincter location nearby external urinary sphincter comprises urinary channel passing from external urinary sphincter to outer hole. Catheter comprises main body allowing installing its distal end inside urinary bladder and its proximal end nearby and distally from sphincter inside urinary path. Aforesaid body features inner passage for draining urea. Cylinder is fastened onto distal end of the main body. Aforesaid cylinder can expand inside urinary bladder to hold distal end inside urinary bladder and prevent primal motion of the main body from location of its use. Catheter comprises also filling tune with its distal end connected with the main body and length sufficient to pass from the main body, via urinary channel and outer hole, when main bode is in location of use. Filling tube and body form filling passage running from proximal end of filling end into the cylinder thought which fluid is fed to fill the cylinder. Spiral section of filling tube is located at such point along filling tube whereat spiral section stays inside urinary channel, nearby and proximally from sphincter when main body is in location of use. Spiral section interacts with urinary path contraction via outer sphincter to prevent distal motion of main body inside urinary path from location of use. In draining, permanent catheter is arranged nearby and distally from sphincter. Catheter has filling cylinder and uses spiral section inside urinary path. Section prevents distal motion of catheter due to contact with urinary path contraction. Proximal motion of catheter is prevented by contact between filled cylinder with urinary bladder. In particular case, a tool may used to insert catheter using inner channel between tool ends. Here, inner channel of aforesaid tool and catheter are made communicating. Flushing fluid is fed via tool inner channel. ^ EFFECT: ruling out surgery intervention, reduced risks of infection. ^ 10 cl, 16 dwg |
