Patent number: 10183105Abstract: An apparatus and method of determining the blood flow rate at which, in an extra-corporeal blood circuit of an extra-corporeal blood treatment apparatus, blood is pumped through the arterial blood line into the blood chamber of the dialyser and out of its blood chamber through the venous blood line is described. The method and apparatus provide for the determination of a plurality of parameters characteristic of the extra-corporeal blood treatment, with a given blood flow rate being determined in each case as a function of one of the characteristic parameters. A blood flow rate which is preset for the blood treatment is selected from the plurality of blood flow rates determined on the basis of the characteristic parameters. The blood flow rate to be preset is selected on the basis of a preset algorithm which may be implemented in software installed on a data processing unit or in hardware.Type: GrantFiled: May 10, 2013Date of Patent: January 22, 2019Assignee: Fresenius Medical Care Deutschland GmbHInventors: Pascal Kopperschmidt, Wolfgang Wehmeyer

Patent number: 10155070Abstract: Embodiments of negative pressure wound therapy apparatuses and methods for using such apparatuses are disclosed. In some embodiments, a negative pressure wound therapy apparatus includes a controller configured to determine a level of exudate in a canister (or a dressing) based at least in part on one or more characteristics of pressure signals generated by a negative pressure source and monitored by a pressure sensor. One such characteristic of the pressure signals can be amplitude, which may increase as a level of exudate in the canister (or dressing) increases. The canister (or dressing) can include a filter configured to become occluded in order to prevent overflow of the canister (or dressing). The controller can be additionally configured to detect and indicate a canister (or dressing) pre-full condition before the filter becomes occluded. More efficient and reliable operation of the negative pressure wound therapy apparatus can thereby be attained.Type: GrantFiled: August 7, 2014Date of Patent: December 18, 2018Assignee: Smith & Nephew, Inc.Inventors: Carrie Lee Childress, William Joseph Jaecklein, Felix C.

Patent number: 10111775Abstract: An applicator for applying fluid medicaments to a corneal surface of a patient, after surgery, includes a circular, ring-shaped member. The ring member creates an aperture which extends between parallel planes, with a wall surrounding the aperture as well as upper and lower openings into the aperture. The wall around the aperture is tapered, and there is a hole that extends through the wall. A hollow shaft is connected in fluid communication with the hole in the wall through which a fluid can be injected into the aperture. A bubble of the fluid can then be cradled in the aperture by the wall, and held therein by surface tension across the lower opening of the aperture. An application of the fluid bubble onto the patient's eye requires only contact between the fluid bubble and the eye, with no need for contact between the applicator and the eye.Type: GrantFiled: March 20, 2015Date of Patent: October 30, 2018Assignee: 1039578 B.C.

Patent number: 10105129Abstract: The draining device 1 is provided with a main body 11 including two side wall members 111 each having a tip end section 111B curved downward, and a connecting portion 12 connecting the side wall members 111. In a manner such that at least upper portions of adjacent side wall members 111 are spaced at a certain distance d and side surfaces 111a of the adjacent side wall members 111 face each other, by connecting the side wall members 111 of the main body 11 with the connecting portion 12, a liquid draining passage R for draining a liquid to a space between adjacent side wall members 111. For this reason, since the liquid inflow cross-sectional area S1 and the passage cross-sectional area S2 increase, it becomes possible to introduce a large amount of liquid into the gap between the side wall members and pass therethrough.Type: GrantFiled: December 5, 2014Date of Patent: October 23, 2018Assignee: KUNIMUNE CO., LTDInventors: Junsuke Akura, Kiran Pokharel

Patent number: 10099001Abstract: An extracorporeal reservoir device including a housing, a venous inlet sub-assembly, and a venous filter. The venous sub-assembly is mounted to the housing and includes a downtube and a luer port connector body. The connector body extends from the downtube and forms a passageway open to a lumen of the downtube. The connector body is arranged such that fluid flow from the passageway merges with a flow path of fluid along the primary lumen at an angle of less than 90°. Secondary blood flow through the port connector body is less likely to induce turbulent flow into venous blood flow within the downtube, and is thus less likely to break up any bubbles carried by the venous blood. For example, at port flow rates of less than 500 mL/minute, fluid flow from the port connector body does not induce turbulent flow into fluid flowing through the primary lumen.Type: GrantFiled: December 7, 2016Date of Patent: October 16, 2018Assignee: Medtronic, Inc.Inventors: Michael Gloss, Eric Boone, Neil Nye, Hanam Pham

Patent number: 10085876Abstract: A female urination device that allows a woman to urinate while standing includes a fluid collecting body and a sanitary napkin. The fluid collecting body has a concave interior surface and a convex exterior surface that are positioned in between a spout and a rim. The concave interior surface delineates a fluid collecting portion, while the rim delineates a vulval opening. The spout is in fluid communication with the vulval opening through the fluid collecting portion, wherein urine is able to freely pass through the fluid collecting body. The concave interior surface and the convex exterior surface are tapered from the rim to the spout, while the spout is tapered away from the concave interior surface and the convex exterior surface to facilitate the control of the flow of urine. The sanitary napkin is positioned around the rim and assists in adhering the fluid collecting body to the woman's body.Type: GrantFiled: October 13, 2015Date of Patent: October 2, 2018Inventor: David Arthur Jones
