Dialysis systems comprising actuators that cooperate to perform dialysis functions and sensors that cooperate to monitor dialysis functions are disclosed. According to one aspect, such a hemodialysis system comprises a user interface model layer, a therapy layer, below the user interface model layer, and a machine layer below the therapy layer. The user interface model layer is configured to manage the state of a graphical user interface and receive inputs from a graphical user interface. The therapy layer is configured to run state machines that generate therapy commands based at least in part on the inputs from the graphical user interface. The machine layer is configured to provide commands for the actuators based on the therapy commands.

A tub is configured to contain a supply of water and is configured to be inserted into a chamber of a humidifier. The tub includes a tub base configured to contain the supply of water. The tub also includes a tub lid and a flow plate provided between the tub base and the tub lid. The flow plate includes a water level indicator configured to indicate a level of the supply of water in the tub base. In addition, the water level indicator includes a generally rectangular portion and a generally triangular portion.

Described are embodiments that include methods and devices for separating components from multi-component fluids. Embodiments may involve use of separation vessels and movement of components into and out of separation vessels through ports. Embodiments may involve the separation of plasma from whole blood. Also described are embodiments that include methods and devices for positioning portions, e.g., loops, of disposables in medical devices. Embodiments may involve use of surfaces for automatically guiding loops to position them into a predetermined position.

A method is provided for detecting leaks in a disposable medical fluid cassette that includes a base and a flexible membrane attached to the base in such a way that the base and the flexible membrane cooperate to at least partially form a fluid passageway. The method includes applying a first force to the flexible membrane, measuring a first physical property of a system that includes the medical fluid cassette a medical fluid pumping machine, removing the first force from the flexible membrane, applying a second force to the flexible membrane, measuring a second physical property of the system, and determining whether the medical fluid cassette leaks based on a comparison of the first physical property and the second physical property.

An autoinjector apparatus is disclosed which comprises a single-use cassette and an autoinjector. The cassette comprises a housing and a sleeve movably disposed in the housing. A syringe may be disposed in the sleeve and secured therein with a lock cap. The lock cap is affixed to a distal end of the sleeve and contacts the distal end of the syringe. A shield remover extends through an opening in a proximal end of the housing for removing a needle shield which covers a needle of the syringe. A cassette identification arrangement is provided on a surface of the housing to enable the autoinjector to identify the cassette. The autoinjector is provided with a detector for reading the cassette identification arrangement.

A cassette for attachment and use with an infusion pump apparatus. The cassette head having a low profile cassette head for attaching to the infusion pump apparatus and a flexible reservoir attached to the cassette head that can be filled with a fluid to be administered to a patient. The reservoir is enclosed in a flexible cover attached to the cassette. The flexibility of the cover and the reservoir inhibits the cassette head from disengaging from the infusion pump apparatus and allows the infusion pump apparatus to be primed by squeezing or pressing the cover and reservoir.

Apparatus and methods for delivering humidified breathing gas to a patient are provided. The apparatus includes a humidification system configured to deliver humidified breathing gas to a patient. The humidification system includes a vapor transfer unit and a base unit. The vapor transfer unit includes a liquid passage, a breathing gas passage, and a vapor transfer device positioned to transfer vapor to the breathing gas passage from the liquid passage. The base unit includes a base unit that releasably engages the vapor transfer unit to enable reuse of the base unit and selective disposal of the vapor transfer unit. The liquid passage is not coupled to the base unit for liquid flow therebetween when the vapor transfer unit is received by the base unit.

An activation mechanism for an aerosol dispenser is presented having a first housing structure, an actuation member movably arranged in the first housing structure, wherein the first housing structure is provided with an actuation member opening in level with the axial position of the actuation member, and an activation member slidably attached to the first housing structure, the activation member slides between a non-triggering position and a triggering position relative to the first housing structure, wherein the activation member has a radially flexible tab portion that is offset from the actuation member opening when the activation member is in the non-triggering position, restricting radial flexing of the tab portion, and wherein the tab portion aligns with the actuation member opening when the activation member is in the triggering position, thereby enabling the tab portion to flex radially inwards to cause movement of the actuation member.

The present disclosure generally relates to the field of nebulizers for aerosol generation and methods of using same for treating diseases and disorders.

An atomizer includes: a liquid storage assembly, including an inner barrel, wherein the inner barrel defines a slide cavity, the slide cavity is defined for receiving the atomization core assembly; and a mouthpiece assembly, disposed at an end of the inner barrel for pushing against the atomization core assembly, such that the atomization core assembly slides relative to the inner barrel, and an end of the atomization core assembly is exposed to an outside of the atomizer. By configuring the mouthpiece assembly to push against the atomization core assembly, the atomization core assembly slides along the slide cavity of the inner barrel, and one end of the atomization core assembly is exposed to the outside. Therefore, it may be difficult for children to disassemble the atomizer core assembly, a risk of children removing the atomization core assembly and causing hazards to themselves may be reduced effectively.
