Patent number: 11793921Abstract: The invention relates to a replaceable cartridge (1) for an ophthalmological apparatus (2), comprising at least one hard region as a housing and at least one soft region, the hard region and the soft region forming inner liquid channels of the replacement cartridge (1). The soft region embodies functional elements of the replacement cartridge (1), said functional elements comprising at least one pump device for pumping liquid into the liquid channels, a valve device for modifying a through-flow cross-section in at least one of the liquid channels, and a pressure-detecting device for determining a liquid pressure in at least one of the liquid channels. The pressure-detecting device comprises a pressure chamber which is connected to one of the liquid channels, and a flexible membrane which peripherally surrounds a coupling element.Type: GrantFiled: November 2, 2017Date of Patent: October 24, 2023Assignee: THIS AGInventors: Thomas Köppel, Marco Zünd, Martin Christoph Heiss

Patent number: 10434256Abstract: A syringe includes a hollow body, a piston and a seal. The hollow body has a surrounding hollow body surface and forms a passage therein. An axis is formed in an axial longitudinal direction of the hollow body and the passage has a rear body opening and a front body opening arranged opposite to one another in the longitudinal direction. A first needle seat is formed at the front body opening, in which a needle cannula is arranged and relative to which the needle cannula is movable along the axis. The piston is arranged in the hollow body and is movable in the passage along the axis. The seal is able to be cancelled such that a receiving chamber and a supply space of the syringe are in flow communication in a release position.Type: GrantFiled: February 10, 2015Date of Patent: October 8, 2019Assignee: SULZER MIXPAC AGInventors: Josef Ettlin, Marco Zünd

Patent number: 10335249Abstract: A syringe for multi-component materials includes a mixer housing, a mixing element, a multi-component cartridge and a mixing head, the mixing head being arranged at least partly within the mixer housing and adjacent to the multi-component cartridge. The mixing head is arranged moveable in an axial direction of the syringe between at least two positions, the at least two positions including a sealed position and a dispensing position. The axial movement of the mixing head is brought about by rotation of at least a part of the mixer housing relative to the multi-component cartridge. The mixing head is axially displaced in a direction opposite to a dispensing direction on a displacement of the mixing head from the sealed position into the dispensing position.Type: GrantFiled: June 19, 2015Date of Patent: July 2, 2019Assignee: SULZER MIXPAC AGInventors: Andreas Hiemer, Marco Zünd

Patent number: 10300506Abstract: A dispensing apparatus includes a body, two inlets for flowable masses and two outlets through which the flowable masses can be dispensed, with one inlet being connected to one outlet and the other inlet being connected to the other outlet through the body. The two inlets are spaced apart from one another by a first spacing and the two outlets are spaced apart from one another by a second spacing, and with the second spacing being larger than the first spacing. A connection ring engages the body and is pre-mounted to the body. The dispensing apparatus is configured to be non-releasably connected to a two-component cartridge via the connection ring for the supply of the flowable masses to the inlets.Type: GrantFiled: July 7, 2015Date of Patent: May 28, 2019Assignee: SULZER MIXPAC AGInventors: Andreas Hiemer, Marco Zünd

Publication number: 20180214641Abstract: A discharger for discharging a predetermined amount of fluid includes a housing defining a longitudinal axis and having a proximal end and a distal end, a discharge section having a discharge passage for the fluid extending between an inlet opening and an outlet opening of the discharge section, a carriage cooperating with the proximal end region of the housing such that the carriage is moveable relative to the housing along the longitudinal axis, and securing devices engageable with each other such that they define a locking position in which the carriage is prevented from being moved along the longitudinal axis, the securing device being disengageable to define a starting position for the carriage by simultaneously applying a first actuating force to the housing and a second actuating force to the carriage, the first actuating force being brought about by a radial compression of the housing.Type: ApplicationFiled: July 29, 2016Publication date: August 2, 2018Inventor: Marco ZÜND

Patent number: 9163764Abstract: A valve for opening and closing a liquid vessel or pouch, which includes a valve body having a central axis, top and bottom sides arranged transversely with respect to the central axis, and a passage opening that extends through the valve body coaxially from the top side to the bottom side. A closure element can be pressed into the passage opening by a spring element coaxially with respect to the central axis from the underside such that the passage opening can be closed in a liquid-tight manner. The closure element includes a first sealing lip which can be pressed into the passage opening with an interference fit P1 and, axially behind said first sealing lip, a second sealing lip, which can be pressed into the passage opening with an interference fit P2, wherein P2 is a stronger interference fit than P1.Type: GrantFiled: February 15, 2011Date of Patent: October 20, 2015Assignee: CWS-boco Supply AGInventors: Marco Zund, Felix Scheiwiller, Markus Erb
