Inline pressure sensor and electrical connector

In general, multiple embodiments of a catheter/fistula needle to bloodline connection assurance device, which secures and strengthens a connection between an extension tube end of a catheter or fistula needle and a bloodline, are provided. In one embodiment, the assurance device includes a clamshell having two halves that open rotatably about at least one hinge. The assurance device includes a male luer portion that pressure seals to the male luer portion of the bloodline connector. The bloodline male luer portion of the device extends to a female luer portion, which is lined with a compressible material that conforms around any industrial catheter/fistula needle connector when the assurance device is closed about the mated connectors. Once the assurance device is closed, this prevents axial movement of the bloodline connector relative to the assurance device.

Catheter/fistula needle to bloodline connection assurance device

Peritoneal dialysis connectors, connector sets, connector systems and methods are disclosed. In an embodiment, a connector includes, a body, a spike located at a first end of the body, a sealing ring sized to seal inside a female connector and located adjacent to the spike end, threads located adjacent to the sealing ring, and at least one barbed ring located adjacent to the threads at a second end of the body. The at least one barbed ring is configured to seal the second end of the body to a tube.

Peritoneal dialysis patient connection system

In general, multiple embodiments of a catheter/fistula needle to bloodline connection assurance device, which secures and strengthens a connection between an extension tube end of a catheter or fistula needle and a bloodline are provided. A first embodiment of the assurance device is configured to be compatible with any industrial catheter/fistula needle female luer connector and is specifically configured for use with a bloodline connector having locking clips which are biased slightly outwardly from the bloodline connector. The first embodiment of the assurance device is cylindrical and includes clamshell halves that open rotatably about at least one hinge. The first embodiment of the assurance device includes an upper, threaded portion and a lower housing portion. The interior wall of the upper portion defines a plurality of barbs configured to engage with distal or moveable ends of the locking clips. Each locking clip is biased slightly outwardly to enable the distal or moveable end of the locking clip to fit between two respective barbs. The barbs are spaced as close together as possible to prevent any axial movement of the bloodline connector when the assurance device is engaged about the mated connectors.

A catheter connection adapter is provided which allows for a user-friendly and mistake-proof connection of a multiple lumen catheter from a dialysis patient to a source of dialysis fluid. The connection adapter contains at least two ports, e.g., one for inflow and one for outflow, and may have a tapered gap between the ports so that an interference fit is made when the ports are inserted into the catheter. In addition, the ports may have a unique key and lock configuration with the catheter such that a fit can only be made when the catheter lumens and the ports are in proper alignment, and the ports may be unconnected to one another so as to provide separate fluid paths for inflow or outflow. The connection adapters are advantageous in that they will allow a multiple lumen catheter to be manually connected to other dialysis equipment following implantation in a patient.
