Patent number: 12076448Abstract: A hemostatic device for promoting the clotting of blood includes a gauze substrate, a clay material disposed on the gauze substrate, and also a polyol such as glycerol or the like disposed on the gauze substrate to bind the clay material. When the device is used to treat a bleeding wound, at least a portion of the clay material comes into contact with blood emanating from the wound to cause the clotting. A bandage that can be applied to a bleeding wound to promote the clotting of blood includes a flexible substrate and a gauze substrate mounted thereon. The gauze substrate includes a clay material and a polyol. A hemostatic sponge also includes a gauze substrate and a dispersion of hemostatic material and a polyol on a first surface of the substrate.Type: GrantFiled: August 19, 2021Date of Patent: September 3, 2024Assignee: TELEFLEX LIFE SCIENCES II LLCInventors: Raymond J. Huey, Denny Lo, Daniel J. Burns, Giacomo Basadonna, Francis X. Hursey

Patent number: 11294404Abstract: An air/oxygen blender, optionally with an associated oxygen analyzer, is provided with an exhaust valve in fluid communication with one or more of a proportioning valve and a gas outlet which periodically opens to vent gas therefrom. The exhaust valve is preferably an electrically actuated valve, most preferably a solenoid valve, controlled by a control unit which periodically opens the exhaust valve. In another embodiment, an oxygen analyzer is provided with an exhaust valve in fluid communication with an oxygen sensing chamber. Preferably, the control unit controls the frequency of exhaust valve opening and the time period of exhaust valve opening. A method of prevention of contamination of a lower pressure source air or source oxygen connected to an air/oxygen blender is accomplished by periodically venting of gas from the exhaust valve.Type: GrantFiled: September 25, 2020Date of Patent: April 5, 2022Assignee: Bio-Med Devices, Inc.Inventors: Raymond J. Huey, Jack N. Sandgren, Shamili Krishnamurthy, Ronald C. Baktis
