An adapter for an evacuator for increasing a suction power of the evacuator includes a suction assembly adapted to be coupled with the evacuator. The suction assembly has a housing, an impeller arranged inside the housing and configured to provide a suction, and an inlet conduit to facilitate a flow of fluid to the impeller. The suction assembly also includes an outlet conduit arranged inside the housing and adapted to be coupled to the evacuator. The outlet conduit is in fluid communication with the impeller and facilitates a flow of the fluid from the suction assembly to the evacuator.

A blood processing apparatus may include a heat exchanger and a gas exchanger. At least one of the heat exchanger and the gas exchanger may be configured to impart a radial component to blow flow through the heat exchanger and/or gas exchanger. The heat exchanger may be configured to cause blood flow to follow a spiral flow path.

A breath-powered, dry powder inhaler, a cartridge, and a pulmonary drug delivery system are provided.

The invention relates to an interchangeable insert (1) for an ophthalmological medical device (99) for aspiration of fluid, such as for discharging fluid as part of suction flushing during an ophthalmo-surgical intervention, such as a cataract operation. According to the invention, this occurs by means of a fluid region (10) for receiving the fluid to be suctioned and a negative pressure region (20), to which a negative pressure can be applied. The fluid region (10) and the negative pressure region (20) are hermetically separated from each other by an at least partially flexible membrane (13).

A nasal cannula includes a distribution conduit running along a virtual distribution path. The distribution path defines a longitudinal direction and has two branch openings. A respective supply conduit branches off from each branch opening. The distribution conduit also has two coupling openings arranged spaced apart from the branch openings. The nasal cannula has a plug via which one of the two coupling openings can be sealed as a closure opening. Another of the two coupling openings is designed as a supply opening. The plug has a flow-directing configuration with an exposed flow-directing surface. In a reference state in which the plug is closing the closure opening, the flow-directing surface is arranged in the distribution conduit in the longitudinal extension region of at least one branch opening and positioned relative to the distribution path to deflect treatment gas flowing in the distribution conduit from the supply opening along the distribution path towards at least one of the branch openings.

A respiration sensor fluid delivery device is provided. The device includes first and second nasal exhalation flow passages that extend through the device, wherein the first and second nasal exhalation flow passages can be aligned in parallel to one another with respect to a nasal respiratory flow direction. A housing of the respiration sensor fluid delivery device fluidly couples with one of a nasal cannula assembly and a respiratory mask assembly. The device provides for respiration monitoring of a subject via a sensor and fluid delivery, such as oxygen, to the subject. Methods of using a respiration sensor fluid delivery device and fluid delivery devices are also provided.

A blood processing apparatus may include a heat exchanger and a gas exchanger. At least one of the heat exchanger and the gas exchanger may be configured to impart a radial component to blow flow through the heat exchanger and/or gas exchanger. The heat exchanger may be configured to cause blood flow to follow a spiral flow path.

In some examples, an aspiration system a catheter and a fluid flow sensor. The fluid flow sensor includes a fluid inlet, a fluid outlet, and a flow oscillator. The fluid inlet is configured to receive fluid from the catheter. The flow oscillator configured to oscillate flow of the fluid through the fluid flow sensor to generate flow-induced vibrations. The fluid outlet is configured to discharge the fluid.

Systems and methods for delivering a gas, such as nitric oxide, are provided. In some embodiments, systems and methods are provided for delivering a gas, such as nitric oxide, in the form of nanobubbles and/or a dissolved gas using a liquid medium.

A liquid dispenser (1) for medical uses wherein a first membrane body (10) is shaped symmetrically with respect to a first frontal median plane (M) and to a second sagittal median plane (N) intersected in a central axis (A) and is delimited at the top by a dome (12); a second body (20) being carried by the first body (10) inside the dome (12) in a position concentric to the axis (A); the second body (20) having a hollow lower portion (22) concentric with the axis (A) and an upper portion (28) provided with a central duct (280) and with at least one first lateral duct (282) (284) (282′) (284′) (282″) (284″) ending in the dome (12), respectively, with a central nozzle (2800) (2800′) (2800″) and at least one first lateral nozzle (2820) (2840) (2820) (2840′) (2820″) (2840″).
