  • Patent number: 11166843
    Abstract: A valved trocar cannula for insertion into an eye includes a trocar cannula having a distal end configured to be positioned within the eye and a proximal end configured to be positioned outside the eye. An elastomeric membrane or seal is attached to the trocar cannula at the proximal end thereof and restricts a free flow of fluid from within the trocar cannula to outside the proximal end of the trocar cannula. The elastomeric membrane includes at least one slit extending therethrough and is arranged to permit the passage of a surgical instrument through the membrane and into the trocar cannula. The slit may through the elastomeric membrane at an oblique angle along a least a portion of the slit. Pressure applied across a first surface or a second surface of the elastomeric membrane in a vicinity of the slit tends to keep the slit in a closed position.

  • Patent number: 9603621
    Abstract: Disclosed are a low-resistance general sealing apparatus for a trocar and a trocar. A sealing ring (3) is compressed between an upper guiding mechanism (1) and a lower guiding mechanism (2). A smooth transition between the upper guiding mechanism (1) and the lower guiding mechanism (2) minimizes the contact area between the sealing ring (3) and a surgical instrument, which not only provides a guiding function when different forms of surgical instrument are inserted or removed, but also maximally transforms a “soft-hard” friction area between the sealing ring (3) and the surgical instrument into a “hard-hard” friction area between the plastics of upper and lower guiding mechanisms and an outer metal sheath of the surgical instrument, thereby greatly reducing the motion resistance, and meanwhile, having an excellent sealing effect. The sealing apparatus and the trocar are also applicable to instruments with diameters between 5 mm and 12 mm.

  • Patent number: 8585393
    Abstract: An edible product is made from a castable mass such as chocolate in a casting device that includes a container for receiving the castable mass and a metering unit. The metering unit has a nozzle block having nozzles facing away from the container and a valve block facing the container. The volume of a metering chamber between the nozzle block and the valve block can be changed by moving the nozzle block relative to the valve block. The casting method comprises steps of a) filling the mass container with the castable mass; b) drawing the mass into the metering chamber by enlarging the metering chamber volume by a first relative motion between the nozzle block and the valve block, and c) discharging the mass from the metering chamber by reducing the metering chamber volume by a second relative motion between the nozzle block and valve block.

  • Patent number: 8568130
    Abstract: The invention relates to a casting machine (1) for casting a flowable mass (M), in particular a flowable mass with suspended solid particles. Said casting machine comprises a mass container (2) for receiving the flowable mass and at least one valve (32, 42; 50; 60; 70; 80; 90; 100; 110; 120) that is fluidically connected to the inner area of the mass container. When the pressure changes in the direction of the valve along the valve passage, said valve is in the open state and in the absence of a pressure change in the direction of the valve passage, said valve is in the closed state. The casting machine also comprises pressure generating means (3, 4, 5, 6, 32, 42) for generating a change in the pressure in the direction of the valve passage.

  • Patent number: 8388337
    Abstract: The invention relates to a casting machine for producing a product intended for human consumption from a castable material, in particular a fat material such as chocolate, for example, having a heatable material container for receiving the castable material; at least one nozzle which is in fluid connection with the material container interior, and a pressure source for generating an overpressure in the material container interior. According to the invention, the nozzle has a nozzle orifice or a nozzle constriction, the open cross section or flow cross section of which is flexible. A process according to the invention for producing a product intended for human consumption from a castable material has the following steps: providing a heated castable material in a material container; generating an overpressure in the material container interior; forcing the material through a nozzle in fluid connection with the material container with simultaneous changing of the flow and/or open cross section of the nozzle.

  • Patent number: 8365967
    Abstract: A valve formed from a frustoconical piece of foldable material, having folds extending from a closable end towards the other end that connects to a container of liquid, each fold having an inner crease extending into the interior region of the nozzle. The valve has a biasing mechanism that may include a spiral spring encircling a nozzle to bias the inner creases inward to cause them to abut each other at the closable end so that the valve is maintained in a closed position. When liquid is forced into the interior region under sufficient pressure it causes the nozzle to move from the closed position to an open position so liquid flows from the interior region out the closable end of the nozzle, and when the pressure on the liquid is removed, the biasing mechanism causes the nozzle to move back to the closed position.

  • Patent number: 8322378
    Abstract: A check valve for one-way flow of a fluid comprises a valve body defining at least two pairs of axially-extending sidewalls, each pair of sidewalls having a pair of resilient lips defining slit opening at the outlet end of the valve. In one embodiment of the invention, the valve body defines three pairs of sidewalls and corresponding lips which are arranged one another so as to provide the check valve with an “I-beam” cross-sectional shape. The I-beam check valve has a compact cross-section, making it suitable for mounting either inside or outside a pipe. The I-beam shape provides support along the valve axis so that the valve does not require any supplemental support structure. In another embodiment, the valve body may define two pairs of sidewalls having a “T-shaped” transverse cross section.

  • Patent number: 8286656
    Abstract: A hollow tubular element is inserted in the descending aorta. The caudad end contains a pressure sensitive passive or preferably, hydraulically or electrically activated, unidirectional valve. A flexible diaphragm situated in a rigid shell affixed over an opening in the element wall divides the shell interior into first and second variable volume chambers. The first chamber opens to the artery. A continuously operating electrical pump is connected to the second chamber through a closed hydraulic system including a multi-valve chamber. The valves regulate fluid flow to the second chamber in accordance with electrical signals from the heart. Fluid flow is directed to the second chamber during cardiac diastole and away from the second chamber during cardiac systole, causing the device to function in a counterpulsation mode. The work of the heart is decreased and coronary blood flow is increased to promote the formation of new coronary collateral channels and the perfusion of the heart itself.

  • Patent number: 7766044
    Abstract: A two-way damper is provided including a retaining member and a baffle. The baffle comprises a flexible member with a first portion secured and held in a fixed position by the retaining member and a second portion normally oriented in a first position, but free to move relative to said first position. The baffle also comprises a third portion, arranged between the first and second portions, being flexible and resilient and allowing the second portion to move to a second position relative to the first position upon the application of a pressure differential across the baffle above a threshold pressure and causing the second portion to return to the first position upon the application of a pressure differential across the baffle below the threshold pressure.

  • Publication number: 20100018597
    Abstract: The present invention is a pressure relief valve structure with pressure relief seam, which is composed of the pipe, and the elastic plug with the edge tightly attached on the pipe wall of the pipe, and the elastic plug is penetrated with slim seam. When the fluid is flowing to the elastic plug through the pipe, and the impact pressure from the fluid is larger than the slim seam of the elastic plug could resist, the intersection along the slim seam would be deformed as a hole to make the fluid flowing through the elastic plug and achieve the purpose of pressure relief.
