Patent number: 11872382Abstract: The present disclosure provides improved technologies relating to medical fluid heating systems and apparatus. In certain embodiments, the present disclosure relates to systems and apparatus for heating a fluid and, more particularly, for quickly and controllably heating a flow of blood or a blood product, for example, for infusion into a patient or for hyperthermia treatment. In particular, in a first aspect, the present disclosure is directed to a system and apparatus featuring single flow path fluid heating (“single path flow”). Moreover, in a second aspect, the present disclosure is directed to a system, apparatus, and related method for efficiently utilizing the thermal energy of an infusate stored in a reservoir (“slack time heating”). Furthermore, in a third aspect, the present disclosure is directed to a fluid heating system and apparatus featuring a vacuum release valve designed to prevent the undesired orientation of deformed inflow tubing (“vacuum release valve”).Type: GrantFiled: November 29, 2017Date of Patent: January 16, 2024Assignee: Belmont Instrument, LLCInventors: John Joseph Landy, III, George G. Brusard, Tristan Dion, Yeu Wen Tseng

Patent number: 11759351Abstract: Described herein is a system for heating and/or cooling a fluid that includes a temperature forcing device having a bottom plate and a top plate hingedly coupled to the bottom plate. At least one of the bottom plate and the top plate has a recess or other area for receiving at least one flexible fluid holder (e.g., a polymer bag). The bottom plate and/or top plate also has at least one protrusion and/or recession in its interior wall(s) such that a fluid passageway in the flexible fluid holder is defined when the fluid holder is placed between the top and bottom plates, and the plates are closed together. The fluid holder then has a fluid inlet for receiving the fluid to be heated and/or cooled and a fluid outlet for delivering the fluid. The fluid, upon being heated and/or cooled by the temperature forcing device, may then be delivered to a patient or may be delivered to another system component, e.g., for additional heating/cooling.Type: GrantFiled: July 24, 2020Date of Patent: September 19, 2023Assignee: Belmont Instrument, LLCInventors: John Joseph Landy, III, Alexander Rick, Tristan Dion, Skylar Nesheim, David Dumais, Yeu Wen Tseng, Chuong Vu, Robert Charles Shea

Patent number: 11123484Abstract: In one set of embodiments a selected section of tubular stock has its ends welded together to form a pillow-like pressure sensing device with an entry tube and an exit tube each configured to facilitate insertion of the pressure sensing device into the flow path of IV infusate in an IV administration set or system. Fluid pressure in excess of a predetermined amount reconfigures the pressure sensing device from a generally oval configuration to a generally circular configuration to restrict and/or cut off fluid flow into the device while permitting fluid flow from the device to reduce the fluid pressure again reconfiguring the device back to its generally oval configuration and permitting fluid flow into and through the device.Type: GrantFiled: August 14, 2008Date of Patent: September 21, 2021Assignee: Belmont Instrument, LLCInventors: John Joseph Landy, III, Michael Gildersleeve

Patent number: 11000407Abstract: An IV pole mountable, therapeutic infusate processing device is incorporated into a hypothermia system to receive therapeutic fluid(s), such as normal saline, peritioneal dialysis solution, or other crystalloid solution, to heat such therapeutic fluid(s) a few degrees centigrade above normal body temperature and to direct the resulting heated infusate to and through a selected anatomical portion of a patients body to raise the temperature of that body portion so as to affect any cancerous or other tumors that may be located therein. The processing device is provided with touch screen controls and visual indicators to facilitate its proper use; while the system further includes temperature and pressure sensors to monitor the hyperthermia processing to insure patient safety.Type: GrantFiled: January 9, 2014Date of Patent: May 11, 2021Assignee: Belmont Instrument, LLCInventors: John Joseph Landy, III, Michael Gildersleeve, Yeu Wen Tseng

Patent number: 10507292Abstract: Presented herein is an infusate heating system with a vacuum release valve that obviates a system halt failure due to inaccurate detection of fluid level in an infusate reservoir.Type: GrantFiled: November 30, 2016Date of Patent: December 17, 2019Assignee: Belmont Instrument, LLCInventors: John J. Landy, III, George G. Brusard, Tristan Dion

Patent number: 10485936Abstract: Presented herein is a system for heating fluid, which, in certain embodiments, includes a fluid separator, a conduit, and a plurality of inductors. The system demonstrates a single flow path without compromising advantages of the existing blood warmers, such that the heat exchanger would not experience stagnant flow that may cause overheating of a local flow path.Type: GrantFiled: November 30, 2016Date of Patent: November 26, 2019Assignee: Belmont Instrument, LLCInventors: John J. Landy, III, George G. Brusard, Tristan Dion

Patent number: 10137257Abstract: Presented herein are various systems, methods, and apparatuses for heating infusate by an induction heater e.g., an electromagnetic heater, and storing thermal energy in a reservoir of thusly heated infusate. In certain embodiments, a system includes a reservoir for containing an infusate, a fluid heater, a diversion valve, a patient line, and a recirculation line.Type: GrantFiled: November 30, 2016Date of Patent: November 27, 2018Assignee: Belmont Instrument, LLCInventors: John J. Landy, III, Yeu Wen Tseng
