  • Publication number: 20040168944
    Abstract: A pain management kit for the administration of medication and a related method of use is disclosed. The pain management kit includes the primary medical supplies for performing a continuous nerve block procedure, preferably in a single, sterile container. Specifically, the kit may contain medical supplies to create a sterile field, perform a local anesthetic procedure and to perform a continuous nerve block procedure. Preferably, the contents of the kit are arranged in the general order of their use.

  • Publication number: 20040116896
    Abstract: A pain management system for the infusion of drug to a wound site includes a pump connected to medical tubing which is connected to an improved infusion catheter for providing uniform delivery of fluid throughout an anatomical region. The infusion catheter is inserted into the body of a patient at a pierce site, spaced from an incision site, and extended to the wound site. The pump causes the drug to flow through the medical tubing, through the infusion catheter and to the wound site. One method by which the infusion catheter is advanced to the wound site includes a guide needle that is placed within an introducer tubing. The needle is pierced through the patient's skin, after which the guide needle is withdrawn and discarded, leaving the introducer tubing in place partially under the patient's skin. The infusion catheter is then threaded through the introducer tubing and advanced to the wound site.

  • Patent number: 6626885
    Abstract: A pain management system for the infusion of drug to a wound site includes a guide needle placed within an introducer tubing. The needle and tubing are pierced through the patient's skin, after which the guide needle is withdrawn The infusion catheter is threaded through the introducer tubing and advanced to the wound site. The introducer tubing is withdrawn and preferably peeled off of the infusion catheter. In accordance with one embodiment, the catheter comprises an elongated tube with a plurality of exit holes along an infusion section of the catheter, and an elongated flexible porous member residing within the tube and forming an annular space between the tube and the member. In accordance with other embodiments, the catheter includes a plurality of exit holes, which combine to form a flow-restricting orifice of the catheter.

  • Publication number: 20030040722
    Abstract: A device and method for the infusion of medicinal fluid at a controlled flow rate to a wound site or the blood stream of a patient is disclosed. A pump delivers fluid under pressure from a fluid source through a continuous and substantially constant flow path and through a supplemental bolus dose flow path. A large volume bolus dose reservoir accumulates a large quantity of fluid from the bolus dose flow path and holds the fluid under pressure. A flow regulator controls the fill rate of the large volume bolus reservoir. The large volume supplemental bolus dose is released from the bolus reservoir upon patient activation of a valve. The release rate of the bolus dose is controlled by the decompression of an elastomeric sphere or spring chamber, by the pressure gradient at the valve and/or by optional flow control tubing.
