  • Publication number: 20240316331
    Abstract: An infusion set includes a tube and a roller clamp for regulating a flow of fluid through the tube. The roller clamp includes a housing that has side walls and a crosspiece connecting the side walls and on which the tube rests. A wheel is supported on running surfaces in or on the side walls so as to be rotatable and displaceable in the longitudinal direction of the housing. The running surfaces face the crosspiece. The lengths of the running surfaces extend in the longitudinal direction of the housing, and the widths of the running surfaces extend in the transverse direction of the housing. Movement of the wheel along the running surfaces alters a cross-section of the tube. The running surfaces each form a substantially punctiform support or contact point with the wheel, on an inner portion of the running surfaces, particularly an inner portion facing the wheel.

  • Publication number: 20230244790
    Abstract: This document describes techniques and systems for performing accelerated secure boot for embedded controllers of vehicles and other embedded systems. Security is maintained by keeping secret, on the device or vehicle, which portions of a software unit are to be used to satisfy an accelerated integrity check. A derivable, pseudo-random number generator based map of these elements may be employed, which is neither predictable nor discoverable. Further measures may be taken even if the secrets are compromised so the accelerated secure boot cannot be deceived on subsequent reboots. Boot time of an embedded system is shorter; the amount of software needing checked by the accelerated secure boot is less than a normal secure boot by factor of eight or more, which strongly accelerates the process. Emerging technologies may be easier adopted for use as embedded controllers and other computer systems that have fast start-up requirements.

  • Patent number: 10857291
    Abstract: A medical pump, in particular an infusion pump for conveying a medium, includes a seating for a hose clamp which is separate from the pump and arranged on the hose. Two clamping portions of the hose clamp which can be moved relative to each other can be transferred into a closed relative position in which they pinch off the hose arranged therebetween in such a manner that it is not possible for any medium to flow through the interior of the hose. Moreover, the clamping portions can be moved with respect to each other into an opened relative position in which the hose arranged between the clamping portions is not pinched off, so that the medium is able to flow through the interior of the hose. The pump is distinguished in that a sensor is provided thereon, in particular in the seating for the hose clamp, which sensor detects at least when the hose clamp is received in the seating—whether their clamping portions are in the closed or opened relative position.

  • Patent number: 10842987
    Abstract: A medical tube clamp for clamping a flexible medical tube comprising: a tube receiving area which is adapted to receive the medical tube, a first clamping portion including a first clamping jaw which is movable relative to a second clamping portion including a second clamping jaw, and a closure system for safely positioning the two clamping portions in more than one snap-fit position relative to each other so that, when the closure system is unlocked, the medical tube can be inserted in and removed from the tube clamp, in an open snap-fit position the inserted medical tube cannot be removed and is not clamped and in a clamping snap-fit position the medical tube is clamped between the first clamping jaw and the second clamping jaw, with the first clamping jaw being configured to be elastically movable relative to the first clamping portion via a connecting member and/or the second clamping jaw being configured to be elastically movable relative to the second clamping portion via a connecting member.

  • Patent number: 9018417
    Abstract: A process is provided for recovering aliphatic monocarboxylic acids having from 4 to 11 carbon atoms from the distillation residue obtained in the oxidation of the corresponding aldehyde by means of oxygen or oxygen-containing gas mixtures in the presence of alkali metal carboxylates or alkaline earth metal carboxylates to form the corresponding monocarboxylic acid and subsequent distillation, characterized in that the distillation residue is reacted with an aqueous acid in a tube reactor and the two-phase mixture flowing out from the tube reactor is introduced into a settling vessel in which the organic phase which separates out has a pH of 4.5 or less.
