A device for administering a fluid product includes a first housing part with a receiver for the product, a second housing part detachably connectable to the first housing part, a piston rod held such that it can be displaced for the exertion of an emptying movement, an actuatable or releasable drive element for the piston rod, a coupling element including a coupling input element that couples the drive element to the piston rod in a coupling engagement, transmits a driving force of the drive element to the piston rod, and triggers the emptying movement, and a decoupling element displaceably connected to the second housing part and coupled to the first housing part such that it is displaced, by a movement of the housing parts in relation to each other when the housing parts are separated into a decoupling position wherein the piston rod is decoupled from the coupling input element.

A fluid pump includes a pump body with a manual operation bulb or a power supply unit provided on an upper end and an inlet and an outlet provided on both sides of a liquid passage. A suction pipe connected to the inlet of the pump body includes a bendable part between an upper suction pipe part and a lower suction pipe part which are formed in a rigid rod shape. A discharge hose shaped as a bellows tube is connected to the outlet of the pump body. A pipe sleeve has ends partially fitted into the upper suction pipe part and the lower suction pipe part. It is installed on the outer circumferential surface of the suction pipe and shaped as a cylinder or a “C” with one end cut out from the cylinder to facilitate moving its position from the bending part to the upper suction pipe part.

This disclosure relates to methods and apparatus for monitoring a remote system. In one arrangement, a plurality of measurement data units are obtained. Each measurement data unit represents a time series of measurements made by a sensor system at the remote system. A first trained machine learning model is used to identify a subset of the measurement data units that have a higher average probability of corresponding to an abnormal state of the remote system than the other measurement data units. Data representing the identified measurement data units is sent over a communications network to a central data processing system. An abnormal state of the remote system is detected by using a second trained machine learning model at the central data processing system to process the data representing the identified measurement data units.

A negative-pressure source is described. The negative-pressure includes a first housing and a second housing configured to be coupled to the first housing to form a cavity. The first housing and the second housing are rotatable on a common axis relative to each other. A membrane is disposed in the cavity and sealed to the second housing to form a first chamber and a second chamber. A motor is disposed in the first chamber, and a clockwork is coupled to the motor and configured to be driven by the motor. A threaded body is disposed in the first chamber and configured to be driven by the motor. The threaded body is configured to rotate on the common axis and to displace the membrane in response to rotation on the common axis.
