Abstract: An intraocular injection system for injecting a substance into an eye globe of an animal or human eye, the system comprising an injection device with a piercing member for injection of the substance into the eye globe, the intraocular injection system providing an automated piercing of the eye globe by the piercing member. The system further comprises a robotic manipulator carrying the injection device, the robotic manipulator adapted and configured to move the injection device to a pre-injection position, a detection device adapted and configured to detect a position of a patch placed onto the eye globe and to control the robotic manipulator to move the injection device to the pre-injection position, the pre-injection position being based upon the detected position of the patch on the eye globe.

Abstract: A sweeping blade assembly for attachment to a vehicle for sweeping a ground surface. The sweeping blade assembly comprises: a blade support for receiving a plurality of blades, a first row of blades and a second row of blades. Each row of blade comprising a plurality of blades which are separated from each other by a gap. The first row of blades and the second row of blades are provided beside (and parallel to) each other and positioned so that a given gap in a given row corresponds to a blade in the other row. In an embodiment, the gap is dimensioned to be smaller in width than the blades whereby a given blade in one row can have a partial overlap of two different blades in the other row. Whereby, the blades can freely move vertically and/or angularly when hitting uneven surfaces, and can be rectangular in shape, and thus reversible when the carbide on one of the edges is worn out.

Abstract: A medical instrument in particular a uretero-renoscope has a proximal head part and an elongate thin shaft for introduction into a small diameter elongate hollow organ. An instrument channel and at least one further channel is disposed within the shaft. The instrument channel is arranged centrally in the shaft.

Abstract: The peristaltic pump is provided with a two-piece housing (2, 3), in which a conveying member (1) as well as a pump tubing section (6) squeezable by the conveying member is received. For fixing the pump tubing section (6) in the housing (2, 3), a tubing holder (4) is provided. Further provided is a connecting element (5) provided with duct shaped connecting sockets (14a, 14b) for connecting tubing sections (15a, 15b). For connecting the pump tubing section (6) to the tubing holder (4), the two ends of the particular pump tubing section (6) are fixed in receptacles (10a, 10b) of the tubing holder (4), which positively enclose the outside of the pump tubing section (6). The connecting element (5) is fixed to the tubing holder (4) by means of a snap-on connection. Thereby, the connecting sockets (14a, 14b) thereof are sealingly connected to the particular pump tubing section (6).

Abstract: The invention relates to a multi-channel peristaltic pump, wherein the housing is constituted by a dimensionally stable support frame (1) and a tube retainer (2) clipped thereto by means of a snap connection. A rotor (3) is provided with three rotatable delivery rolls (33a, 33b, 33c) and is mounted on the support frame (1). The tube retainer (2) is provided with a tube bed body (25) which defines on the inside a tube bed and at the end two legs (2a, 2b). Flexible tube sections (43) are received in the tube bed and can be squeezed by the delivery rolls (33a, 33b, 33c) to peristaltically deliver a medium. The two legs (2a, 2b) are resiliently elastic so that they can be radially clipped into the support frame (1). The tube bed body (25) has a substantially omega-shaped design and is provided with a continuous inlet and outlet area that ensures a peristaltic delivery of the respective medium with only few pulsations.

Abstract: The invention relates to a peristaltic pump in which a case is formed by a dimensionally stable supporting frame (1) and by a tube reception device (2) formed thereon by clipping. A rotor (3) provided with three rotatable transport rollers (33a, 33b, 33c). Said tube reception device (2) is provided with a tube bearing body (25) which forms a bed for the tubes on the internal surface and comprises two legs (2a, 2b) on the ends thereof. The tube flexible sections (43) are compresses by said transport rollers (33a, 33b, 33c) in order to ensure the peristaltic conveyance of a medium. The two legs (2a, 2b) are elastically deformable in a radial direction in order to be elastically adaptable on the supporting frame (1). The bearing body (25) is substentially omega-shaped and provided with uniform input and output areas which ensure a medium continuous low-pulsed peristaltic conveyance.

Abstract: A hose cartridge for a peristaltic pump comprises a cartridge housing provided with a lateral recess. The recess is delimited at least partially by an element having essentially the shape of a segment of a circle. A roller wheel of the peristaltic pump can engage that recess once the cartridge is attached to the peristaltic pump. The cartridge housing is provided with two support arms, and a groove extends from one of the support arm along three outer side faces of the cartridge housing to the other support arm. The ends of the support arms are provided each with a hose take-up member for retaining stoppers attached to a hose section. Such a hose cartridge is of very compact design ensures an easy handling.

Abstract: The invention provides a method and an assembly for the batch-wise preparation of a liquid product constituted by a mixture of at least one primary liquid and at least one secondary liquid. The secondary liquid and liquids, respectfully, to be meteredly added to the flowing primary liquid are displaced, before the metered addition, from a main reservoir to a buffer reservoir. Each of the secondary liquids is conveyed by means of an associated conveyor operating according to the displacement principle. The conveyors are hydraulically operated, whereby the same liquid can be used both as hydraulic operating medium and as primary liquid. A mixing element is provided for mixing the primary liquid with the secondary liquid or liquids. The primary liquid is under pressure, since it can be blended with carbon dioxide. The secondary liquid or liquids are supplied to the mixing element under a pressure that is higher than the pressure inherent to the primary liquid in the mixing element.
