Patent number: 9180247Abstract: A device for dispensing fluid to a patient and indicating a fluid flow condition. The device includes a reservoir configured to provide a source of fluid under pressure. A continuous flow path in fluid communication with the source of fluid provides a continuous and substantially constant flow rate of fluid from the source to a patient. The device further includes at least one pre-biased indicator in fluid communication with the continuous flow path. The pre-biased indicator is configured to provide a discrete visual signal that the pressure of the fluid in the continuous flow path is different from a predetermined level of pressure, thereby indicating a fluid flow condition.Type: GrantFiled: April 8, 2013Date of Patent: November 10, 2015Assignee: AVENT, INC.Inventor: Roger Dillard Massengale

Patent number: 8328771Abstract: 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 al 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. In accordance with one embodiment of the catheter, 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 tube having a plurality of exit holes in a side wall of the tube. The exit holes may combine to form a flow-restricting orifice of the catheter.Type: GrantFiled: March 29, 2011Date of Patent: December 11, 2012Inventor: Roger Dillard Massengale

Publication number: 20110190731Abstract: 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.Type: ApplicationFiled: March 29, 2011Publication date: August 4, 2011Applicant: I-FLOWInventor: Roger Dillard Massengale

Patent number: 7815604Abstract: 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.Type: GrantFiled: December 29, 2005Date of Patent: October 19, 2010Assignee: I-Flow CorporationInventors: Roger Dillard Massengale, Kenneth W.
