DETAILED DESCRIPTION OF THE INVENTION

[0027] The present invention has utility as a system and method for integrated multi-lumen tubing for intravenous infusion lines, vacuum lines, and monitoring lines for attachment to percutaneous access devices. The integration of the intravenous infusion lines, vacuum lines, and monitoring lines that connect to the PAD and other inserted instruments organizes the myriad of intravenous infusion lines, vacuum lines, and monitoring lines that connect to the PAD and other inserted instruments that tend to get tangled, interfere with patient comfort and movement, and are potentially difficult for health care workers to change and maintain.

[0028] While embodiments of the integrated multi-lumen tubing are depicted in the accompanying figures as being used with an embedded percutaneous access device (PAD), it is appreciated that it is applicable to a variety of such implant appliances including a catheter, a PICC line, an IV, a Steinman pin, and a Kirschner wire. Embodiments of the integrated muti-lumen tubing provide for the hermaticity in the vicinity of the skin-appliance (PAD) interface with fluid exudate or transudate egres sing from the vicinity of the skin-PAD interface via a vacuum or low pressure tube.

[0029] Referring now to the figures, FIG. 4 illustrates an inventive embodiment of a ribbon cable 300 with a webbing 306 that links two or more lumens or tubes for an intravenous infusion line 302 and a vacuum line 304 for attachment to percutaneous access devices. The ribbon cable 300 is generally made of a clear (transparent or translucent) anti-kink material so fluids being transported are visible, as well as to make obvious if any obstructions occur. Non-limiting examples of materials for the lumens or tubes include synthetic polymers such as polytetrafluoroethylene (PTFE), polyvinyl plastic (PVC), polyethylene, or polypropylene plastic. PVC tubing is softened with plasticizers to make it flexible. The webbing 306 is made so that the web may be teared apart to separate the lumens (302, 304) at the terminating ends to facilitate connections. The terminations 308 may be color coated or keyed to avoid improper connections.

[0030] FIG. 5 illustrates an inventive embodiment of an expanded version 320 of web linked integrated muti-lumen tubes for an intravenous infusion line 322, a vacuum line 324, and a monitoring line 326 for wound healing measurements for attachment to percutaneous access devices. A set of insulated wires 328 may be also be attached to the monitoring line 326 for transmitting impedance measurements. Measured parameters that correlate to a degree of wound hermaticity may be incorporated into the design of a percutaneous skin access device (PAD), a bone anchor, a wound dressing, or a bandage. The degree of wound hermaticity is related to impedance measurements performed on the patient's skin, via measurements of humidity in a vacuum line 324 to the PAD, or via measurements of local tissue oxygenation in the immediate vicinity of the PAD as read via monitoring line 326. The hermaticity measurement parameters may be communicated by the wire 328 to a computing or a communication device for immediate or remote monitoring.

[0031] FIG. 6 illustrates an inventive embodiment of a cable 340 with a sheath 342, which is generally clear but is shown as opaque for illustrative clarity, covering integrated muti-lumen tubes for an intravenous infusion line 344 and a vacuum line 346 for attachment to percutaneous access devices. The sheath 342, which is flexible, holds the lumens together and avoids entanglements. It is appreciated that while only two lumens are shown, more than two lumens may be enclosed in the sheath 342 in accordance with embodiments of the invention.

[0032] FIG. 7 illustrates a system 400 for suppling intravenous (IV) fluids and a vacuum via an embodiment of the integrated muti-lumen tubes to the modular external interface seal 200 of FIG. 2 for PAD appliances. An intravenous bag or bottle 402 is shown supplying an infusion pump 404. The IV fluids are supplied via an infusion line 408 to the driveline 220 of the PAD 200. A vacuum line 410 attached to the infusion line 408 with web 306 terminates in a vacuum pump 22 and the vacuum line 222 of the PAD 200.

[0033] FIG. 8 illustrates a system 440 with an integrated device 442 with a collocated infusion pump 404 and vacuum pump 22 for suppling intravenous fluids and a vacuum, respectively via an embodiment of the integrated muti-lumen tubes to the modular external interface seal of FIG. 2 for PAD appliances. An intravenous bag or bottle 402 is shown supplying an infusion pump 404. The IV fluids are supplied via an infusion line 408 to the driveline 220 of the PAD 200. A vacuum line 410 attached to the infusion line 408 with web 306 terminates in a vacuum pump 22 and the vacuum line 222 of the PAD 200.
