Publication number: 20230226340Abstract: A medical female connector (10) for controlling a fluid flow is disclosed, as well as a method for its manufacturing, and medical devices including such a female connector. A tubular plunger (40) and a flexible valve member (60) are inserted into a housing (20). A distal end (42) of the plunger (40) is located at a distance proximally from the distal end (22) of the housing (20). In a flow stop configuration, the flexible valve member (60) seals a flow path (44) through the tubular plunger (40). In a flow configuration, the valve member (60) is compressed by a male connector (90) and deformed by the plunger (40) to allow a fluid flow through the plunger (40). A frusto-conical female sealing surface (24) is arranged to form a seal with the male connector (90). An entrance opening (25) of the housing (20) presents a diameter equal to or larger than the maximum diameter (d1) of the female sealing surface (24).Type: ApplicationFiled: June 23, 2021Publication date: July 20, 2023Applicant: CYTO365 ABInventor: Micael Törnblom

Patent number: 10960135Abstract: A valve and a method for administering a plurality of drug fluids to a patient are disclosed. For each drug fluid, the valve may be rotated into a selected drug position associated with the drug fluid. With the valve being in the selected drug position, a backpriming may be performed of a connector line of a drug container containing the drug fluid. Thereafter, the drug fluid may be administered with the valve being in the same selected drug position. Thereafter, the valve may be flushed, optionally while maintaining the same selected valve position.Type: GrantFiled: July 12, 2019Date of Patent: March 30, 2021Assignee: CYTO365 ABInventor: Micael Tornblom

Patent number: 10449351Abstract: A drug administration valve (100) comprises a valve housing (200) having a plurality of drug inlets (D1 to D4) for receiving drug fluids, such as cytostatic, one flushing inlet (F) for receiving a flushing fluid, and an outlet (O). A valve member (300) rotationally arranged in the housing has a passageway (320; 321) presenting a single inlet (322) and a single outlet (324). The valve member (300) presents a plurality of drug positions for guiding an associated drug fluid to the outlet (O), and one or more flushing positions for guiding a flushing fluid through the same passageway (320; 321) as the drug fluids in order to flush said passageway (320; 321) from any drug residuals. The valve member (300) is prevented from rotating from one drug position to another drug position without passing one of said flushing positions.Type: GrantFiled: September 10, 2014Date of Patent: October 22, 2019Assignee: CYTO365 ABInventor: Micael Törnblom

Patent number: 9764126Abstract: In accordance with the present inventive concept, there is provided a valve for administration of a plurality of drug fluids, such as cytostatics. The valve comprises: a housing having a plurality of circumferentially distributed primary inlets for receiving a respective one of the drug fluids and a secondary inlet for receiving a secondary fluid, such as a neutral fluid, an outlet, and a valve member arranged in the housing. The housing has a plurality of primary valve positions in each of which an associated one of the primary inlets is connected to the outlet, and a plurality of intermediary valve positions in each of which the secondary inlet is connected to the outlet. Moreover, the valve member has a outer surface sealingly engaging an inner surface of the housing, such that the primary and secondary inlets are sealingly connected to openings arranged in the outer surface of the valve member in each of the primary and intermediary valve positions, respectively.
