A drug delivery assembly comprising a sensor system in combination with an indicator arranged to rotate, the amount of rotation being indicative of the size of an expelled dose amount. The sensor system comprises a sensor assembly adapted to measure a rotational position and/or a rotational movement of the indicator, the sensor assembly comprising a sensor element adapted to be operated at a non-constant sampling frequency. A processor is configured to determine on the basis of measured values from the sensor element rotational position(s) and/or amount of rotational movement of the indicator, as well as rotational speed of the indicator. To optimize energy consumption the processor is configured to dynamically control the sampling frequency in response to the determined rotational speed.

A method of inserting a lubricant free stopper into a lubricant free syringe barrel or lubricant free cartridge tube is disclosed. The method includes (1) inserting a stopper with a sealing rib into a placement region, (2) lowering the body of the insertion tube into a syringe barrel or cartridge tube to a position located past the barrel flange or top of the cartridge tube, (3) maneuvering the stopper to a distal opening of the insertion tube using an insertion pin, (4) retracting the insertion tube while the stopper remains in a fixed position within the syringe barrel or cartridge tube, and (5) fully retracting the insertion pin and the insertion tube from the syringe barrel or cartridge tube. The method is lubricant free or substantially lubricant free. The insertion tube may be electropolished and/or extrude honed.

Self-righting articles, such as self-righting capsules for administration to a subject, are generally provided. In some embodiments, the self-righting article may be configured such that the article may orient itself relative to a surface (e.g., a surface of a tissue of a subject). The self-righting articles described herein may comprise one or more tissue engaging surfaces configured to engage (e.g., interface with, inject into, anchor) with a surface (e.g., a surface of a tissue of a subject). In some embodiments, the self-righting article may have a particular shape and/or distribution of density (or mass) which, for example, enables the self-righting behavior of the article. In some embodiments, the self-righting article may comprise a tissue interfacing component and/or a pharmaceutical agent (e.g., for delivery of the active pharmaceutical agent to a location internal of the subject). In some cases, upon contact of the tissue with the tissue engaging surface of the article, the self-righting article may be configured to release one or more tissue interfacing components. In some cases, the tissue interfacing component is associated with a self-actuating component. For example, the self-righting article may comprise a self-actuating component configured, upon exposure to a fluid, to release the tissue interfacing component from the self-righting article. In some cases, the tissue interfacing component may comprise and/or be associated with the pharmaceutical agent (e.g., for delivery to a location internal to a subject).

Modules for housing electronic and electromechanical medical equipment including a system to measure and record administration of one or more IV medications or fluids for IV administration.

A precision syringe includes a syringe barrel and plunger that has a base, an internal portion, and an external portion. The internal portion of the plunger extends longitudinally into the syringe barrel. The internal portion has a first end coupled to the base and a second end that is configured to push fluid out of and/or suction fluid into the syringe barrel. The external portion extends longitudinally along an outer surface of the syringe barrel. The external portion has a first end coupled to the base and a second end that is configured to receive an applied force that causes the plunger to move relative to the syringe barrel so that the second end of the internal portion is actuated through a portion of the syringe barrel (e.g., to dispense fluid from or suction fluid into the syringe barrel).

A tube clamp closes a flexible tube by applying a pinching force to walls of the flexible tube. The clamp includes a housing connected to a circular flange, the circular flange including a tubular wall surrounding a central bore and including at least one slot in the tubular wall sized to accept the flexible tube. A pinching element is positioned inside the central bore and is rotatable about a central axis of the circular flange. The pinching element includes a pinching projection that has a cross-sectional shape bound by a partial circle, and the partial circle has a radius substantially same as an inner radius of the tubular wall.
