Abstract: A system for compacting cannabis in a cannabis cone comprises i) a cone gripper that is movable between an open position and a closed position around the cannabis cone; wherein, while in the closed position, the cone gripper applies pressure onto the cannabis cone that is sufficient to hold the cannabis cone; ii) a compaction rod, having a tip, for compacting cannabis in the cannabis cone, the compaction rod being reciprocable along an axis between a retracted position, wherein the tip is out of the cannabis cone, and an extended position, wherein the tip is inserted in the cannabis cone; and iii) a protective collar that is movable within the cannabis cone, coaxially thereof, near the open top thereof, so as to define a barrier between the compaction rod and the cannabis cone when the compaction rod reciprocates in the cannabis cone.

Abstract: A cannabis joints filling system includes a cannabis joint filling apparatus for receiving and holding a paper cone along a longitudinal axis and for receiving and pre-compacting a predetermined quantity of cannabis into the paper cone; and a cannabis feeding system including i) a weighing scale, ii) a cannabis feeding apparatus adjacent the weighing scale for receiving cannabis in bulk and for controllably outputting a predetermined portion of the cannabis in bulk onto the weighing scale, and iii) a single portion cannabis distributing device, including two cups that are sequentially movable between a) a cannabis weighing position, wherein one of the two cups cooperates with the weighing scale to measure the predetermined portion of the cannabis, and b) a cannabis distributing position, where the predetermined portion of the cannabis is fed to the cannabis joint filling apparatus.

Abstract: A platen assembly positionable opposite a pumping mechanism of an infusion pump has a first platen member rotatably coupled to the pump to pivot about a first hinge axis and a second platen member rotatably coupled to the first platen member to pivot about a second hinge axis different from the first hinge axis. When the platen assembly is in a pump operating position, respective platen surfaces of the platen members follow a single surface profile, for example an arcuate surface profile in the case of a curvilinear peristaltic pump. The platen assembly may have a damage-tolerant design including a plurality of alignment counter-features arranged to mate with corresponding alignment features on the pump, wherein the platen assembly may still close after the pump is dropped or damaged only if resulting deformation of the platen assembly is within an allowable tolerance for safe pumping.

Abstract: In an infusion pump operable to deliver fluid to a patient at a programmed therapy flow rate, air-in-line sensing is improved by commanding the pumping mechanism to deliver a bolus volume of fluid at a flow rate higher than the therapy flow rate when an uninterrupted volume of air is detected that exceeds a first threshold. In many cases, the bolus will be effective to clear microbubbles from an observation zone of the air-in-line sensor to avoid an air-in-line alarm condition. If the uninterrupted volume of air continues to grow beyond a second threshold in spite of the bolus, then an alarm may be triggered. The invention reduces false alarms.

Abstract: An infusion pump has an optical cassette detection system for determining whether or not a cassette of an administration tubing set is properly loaded in the pump. Operation of the pump may be enabled or disabled based on a determination of the cassette detection system. The cassette detection system includes a light emitter and a corresponding photosensitive detector, and a window carried by the cassette that includes a fluorophore. When the cassette is properly loaded in the pump, an excitation light beam from the emitter enters the window and excites the fluorophore, causing emission light in a wavelength band distinct from that of the excitation beam to be transmitted out of the window for receipt by the detector. The detector signal is evaluated by signal evaluation electronics to determine if the signal level is above a predetermined threshold, indicating the cassette is loaded.

Abstract: An infusion pump has an optical detection system for determining whether or not a cassette of an administration tubing set is properly loaded in the pump. Operation of the pump may be enabled or disabled based on a determination of the optical detection system. The optical cassette detection system includes a light emitter and a corresponding light detector on non-coincident emission and detection axes, and at least one optical element carried by the cassette. When the cassette is properly loaded in the pump, light from the emitter is redirected by the optical element from the emission axis to the detection axis for receipt by the detector, which registers an increased signal level. The detector signal is evaluated by signal evaluation electronics to determine if the detector signal level is above a predetermined threshold, indicating presence of the cassette.

Abstract: A feeding bag system and method of preparing a feeding system is described. The system can include an adapter cap having a threaded portion for threadbly receiving the feeding bottle, a funnel-shaped portion having a tip portion configured to cooperate with an enteral feeding tube, a vent passageway disposed through the adapter cap, and a fluid passageway disposed through the funnel-shaped portion. The system can also include a bag configured to be suspended by a medical hanger. The bag may include walls defining an inner cavity, an upper opening for positioning the feeding bottle therethrough, and a sealed lower portion. The sealed lower portion can include an aperture configured to receive a portion of the adapter cap therethrough.
