Definitions

  • the pump subsystem 10 may be any commercially available infusion system, such as the INFUSAID Model 400, which employs a side port.
  • the pump may be constant flow device or any flow metering or other pumping system, such as a programmable valve system, as illustrated in U.S. Patent 4,838,887.
  • a pump 10' a refill septum 14 and a drug reservoir, schematically illustrated as element 16.
  • element 16 a drug reservoir
  • a sideport 18 having a septum 20 and an outlet catheter.
  • tip patency at the outlet 50 can be evaluated without a drug being infused into the system.
  • tip patency can be assessed utilizing the tip access port 34. It will be appreciated that utilizing those same techniques the catheter 26 exiting the pump sideport 18 can be evaluated for patency utilizing the sideport itself. This system thus permits a determination of patency at the tip. Such is important because that is a source of blockage in many applications.
  • a drug which resides in the catheter 26 exiting the side port 18 can be removed without infusing drug into the patient. This can be done utilizing both the side port 18 and the tip access port 34.
  • the drug By attaching a drain line to the sideport and an infusion line to the tip access port, the drug can be removed from the catheter without bodily fluids entering the catheter. That is, a flushing fluid is introduced via the lumen 44. Since a drain line is attached to the side port, a pressure differential exists in the two lumens with the lower pressure in the catheter 26. A fluid communication loop is thus established without bodily fluid entering the catheter tip 50.
  • Another important advantage is that blockage at the catheter tip 50 can be flushed via the tip access port 34 without drug infusion into the patient. This is done by direct flushing utilizing the lumen 44 which, as illustrated in Figs. 1 and 2, merges with the lumen 27 carrying the drug approximal to the tip 50.
  • insulin can be removed from the catheter lumen 27 attached to the sideport, as well as the side port lumen proximal to the catheter by utilizing the tip access port 34 and the sideport 18. In this application drainage would be at the sideport 18 and infusion would be at the tip access port 34.
  • insulin removal is required prior to the alkaline flush during a magnet procedure. This procedure is one that employs a magnet placed over a pump having valves that open and close such as an Infusaid M1000 (see also U.S. Patent 4,838,887). The magnet holds both inlet and outlet valves open.
  • An alkaline flush solution is loaded into the pump 10' and extracted via the sideport 18 through septum 20. The alkaline solution dissolves any precipitation within the pump flow path. Again, this insulin removal technique prevents hypoglycemia.
