Bladder-neck indwelling catheter with an opening and closing device which can becontrolled in a contactless manner to empty urine from the bladder

摘要

All the functions of preart bladder-neck indwelling catheters can only be externally operated and controlled. The inventive bladder-neck indwelling catheter (1) contains a catheter tube (2) having two blocking pockets (3, 6) and delivery lines (10, 15) which lead to said blocking pockets (3, 6). The catheter also comprises a power supply unit (13), a receiving and control assembly (12), a blocking pocket valve (11) and a magnetic valve (9). The magnetic valve is electrically connected to the control unit and can be controlled remotely or by hand. In addition, said magnetic valve is arranged in a channel (20) provided for carrying away urine. A flexible insertion device (29) is located next to the bladder-neck indwelling catheter (1). The forward end of said insertion device fits inside the catheter tube (2) and is provided for inserting and withdrawing the bladder-neck indwelling catheter (1).
