A medical device includes a first housing portion (FHP) and a second housing portion (SHP) configured to be to be movable relative to each other from a first position to operatively engage at a second position to couple at least one of a drive device and a needle-inserting device supported by one of the FHP and the SHP to a reservoir supported by the other of the FHP and the SHP. Electronic circuitry configured to detect at least one of a first magnetic interaction between a magnet and at least one of a first magnetically attractive material and a first magnet-responsive device and a second magnetic interaction between the magnet and at least one of a second magnetically attractive material and a second magnet-responsive device, and to provide a signal or a change in state in response to detecting at least one of the interactions.

A one-piece fluid line connector for connecting a fluid feed line to a fluid container includes a main body having a male luer lock fitting, and a cap coupled to the main body by a living hinge. The living hinge is configured such that the cap is moveable to an aligned position in which the cap is aligned with a central axis of the male luer lock fitting of the main body. The cap includes a through-hole configured such that, in the aligned position, the shape of the through-hole permits a correspondingly-shaped female luer lock fitting to pass therethrough and engage the male luer lock fitting.

Certain embodiments provide multi-medicament or single medicament infusion systems for preventing the cross-channeling or improper delivery of medicaments. The system may include one or more of an infusion pump, medicament cartridges, cartridge connectors, a multi-channel fluid conduit, and an infusion set. The medicament cartridges may be sized and shaped differently such that the medicament reservoirs can only be inserted into the pump under selected configurations.

Disclosed is a set of holding arrangements for a head harness in the region of a patient interface. The set comprises at least two holding arrangements which are distinguishable by identification markings and/or codings and are unambiguously assignable.

A wearable infusion pump allows a user to insert a program key into a housing of the pump to select a continuous dosage rate. Program keys are shaped to close contacts on a printed circuit board within the housing to communicate the selected dosage rate to a microprocessor. In this way, a single disposable pump, sold with one Stock keeping unit (SKU), can be used to deliver a plurality of dosage rates. The disposable pump is provided with an on-board display and a one-button on-board user operable control. In preferred embodiments, the infusion pump according to the invention may be used for continuous delivery of insulin in management of Type II diabetes.

Phyto material tablets, tablet vaporizers, methods and apparatus for forming phyto material tablets. The tablets are formed to increase vaporization efficiency. Tablets can include break regions to facilitate fracturing into multiple pieces for vaporization. The tablets can also include multiple layers of different phyto material mixtures. Compression molds are used to shape the tablets. The compression molds can be provided on a rotational assembly to facilitate rapid manufacturing of multiple tablets. The vaporizers include heating chambers that are configured to increase the surface area of the tablets exposed for vaporization. The heating chambers include compression or fracture members that compress and/or encourage fracturing of the tablets to assist vaporization.

The principles and embodiments of the present invention relate to methods and systems for safely providing NO to a recipient for inhalation therapy. There are many potential safety issues that may arise from using a reactor cartridge that converts NO.sub.2 to NO, including exhaustion of consumable reactants of the cartridge reactor. Accordingly, various embodiments of the present invention provide systems and methods of determining the remaining useful life of a NO.sub.2-to-NO reactor cartridge and/or a breakthrough of NO.sub.2, and providing an indication of the remaining useful life and/or breakthrough.

An intravenous (IV) tubing fitment is provided. The IV tubing fitment includes a unitary body. The unitary body includes a first end configured to couple to a first tubing, a substantially hemispherical surface adjacent to the first end, and a cylindrical body adjacent to the substantially hemispherical surface. The cylindrical body including a plurality of wings and is configured to receive a second tubing. The unitary body is configured to be received into a mating recess of a fluid delivery device such that the substantially hemispherical surface is uniformly mated with a substantially identical surface of the mating recess, and the cylindrical body is positioned outside of the mating recess.
