User interface improvements for medical devices

A medication delivery apparatus for use with a medication container includes a housing, a fluid conduit at least partially extending within the housing and configured to deliver medication within the medication container to a patient, a medication port extending from the housing and configured to be coupled to a fluid outlet of the medication container, the medication port being fluidically coupled to the fluid conduit, and at least one sensor disposed within the housing to generate information characterizing administration of the medication for processing by a remote data collection system. The housing can have a size and shape that enables it to be supported by a first hand of a user while the user administers the medication from the medication container via the medication port using a second hand of the user. Related apparatus, systems, and techniques are also described.

Medication injection site and data collection system

An ultrasonic transducer for use in a fluid medium is proposed. The ultrasonic transducer includes at least one transducer core which has at least one acoustic/electric transducer element, in particular a piezoelectric transducer element. The ultrasonic transducer furthermore includes at least one housing, at least one housing opening being at least partially sealed against the fluid medium with the aid of a sealing film which is connected to the transducer core. The sealing film has at least one expansion deformation which is configured to permit a relative movement between the transducer core and the housing.

Ultrasonic transducer for use in a fluid medium

A medication and identification information transfer system is provided that includes a primary medication container, a secondary medication container, a secondary container label and a medication information transfer apparatus. The medication information transfer apparatus, when coupled to the primary medication container, can transfer information indicative of the contents of the primary medication container to a medication delivery device such as an intelligent injection site. The medication information transfer apparatus has a shape and size enabling it to be connected to an adapter for removal of medication from the primary medication container which enables transfer of the medication to a secondary container while simultaneously transferring information about the medication in the primary medication container to the injection site. In some implementations, the medication injection site can be placed on a fluid delivery line for infusion into a patient. Related apparatus, systems, methods and kits are also disclosed.

Medication and Identification Information Transfer Apparatus

A fluid flow meter estimates the velocity of water or another fluid flowing through pipe by comparing measurements of the water velocity to one or more pre-determined templates. The fluid flow meter may collect measurement signals from one or more flow sensors, estimate the fluid velocity or flow rate by comparing the measurement signals to the template, and either store the comparison results in local memory, transmit the results to a remote memory or server, or both. In some embodiments, the fluid flow meter transmits the results to a server via a wireless interface. The transducers and processing system can be powered by a battery, a power line, or, for manifolds installed outdoors, a solar cell. Example transducers and processing systems may also have a passive wake-up feature for power reduction; that is, they may only draw power when water or another fluid flows through the pipe.

Methods and apparatus for fluid flow measurement

A device for determining and/or monitoring volume and/or mass flow rate of a medium that flows in a direction of flow through a pipeline/measuring tube of inner diameter. The device comprises at least two ultrasonic transducers that emit and/or receive ultrasonic measuring signals along defined sonic paths and a control/evaluation device which determines the volume flow rate and/or the mass flow rate of the medium to be measured inside said pipeline/measuring tube based on the ultrasonic measuring signals according to the travel-time difference principle. In order to provide a multichannel ultrasonic flowmeter, at least one reflector element is placed in the interior of the pipeline/measuring tube. The reflector element has a defined distance from the inner surface of the pipeline/measuring tube and is placed within the sonic path of the ultrasound measuring signals running through the pipeline/measuring tube.

Zumindest ein Ultraschallsensor (1up, 2up, 3up; 8) ist in einem ersten Bereich der Rohrleitung (5) bzw. des Messrohres (5) angeordnet; zumindest zwei Ultraschallsensoren (1dn, 2dn, 3dn) sind in einem zweiten Bereich der Rohrleitung (5) bzw. des Messrohres (5) derart angeordnet, so dass die Ultraschall-Messsignale die Rohrleitung (5) oder das Messrohr (5) in bzw. entgegengesetzt zur Stromungsrichtung (S) des Mediums (4) auf Schallpfaden (SP) mit unterschiedlicher Lange (L) durchlaufen.
