  • Patent number: 4632670
    Abstract: A suture tab for holding a catheter in place on a patient is described. The suture tab includes a central opening adapted to receive and hold a catheter in place. A slit extends from one edge of the suture tab to the central opening such that the catheter must pass through the slit to arrive at the central opening. A suture placed through the suture tab serves to both close the slit and hold the suture tab in place on the patient.

  • Patent number: 4601701
    Abstract: The catheter includes multiple lumens which connect to a single mixing chamber at the catheter hub. Each of the multiple lumens is connected both to the mixing chamber and to a port connected to a catheter connector. By selecting a plug of suitable length, one or more of the side ports connected to the central mixing chamber can be plugged whereby the connection from that particular side port will be prevented from going into the mixing chamber. Accordingly, it is possible to have a single catheter connection into the mixing chamber which connects to multiple lumens of the catheter without any additional plumbing requirements.
