  • Tubing administration set for use in peritoneal dialysis
    Patent number: 5423768
    Abstract: Apparatus for administering dialysis, including a separable tubing coupling (32). The tubing coupling (32) consists of a hollow cylindrical element (42, 44) insertable into the lumens of the distal and proximal regions of the fluid delivery tube (16), and has a scored circumference at which the coupling can be broken-off by application of an adequate bending force. The device allows rapid and reliable disconnecting of the patient from the dialysis apparatus, without the need for scissors or a knife to be employed.
