The present disclosure provides a spray head and a device for intranasal spraying of liquid medicine, comprising: a nozzle, which has a flow channel running through the axial direction, and the distal and proximal ends of the flow channel are the flow channel outlet and inlet, respectively; a water core circumferentially arranged with a water trough configured inside the flow channel; and the outlet tube, curved in shape, comprising a parallel section and an inclined section integrally connected. The end of the inclined section extends from the flow channel inlet to the inside of the flow channel and is circumferentially sealed to the inner wall of the flow channel, so that when the fluid flows in from the parallel section, it flows out from the inclined section into the inside of the flow channel and after passing through the water trough, it ejects from flow channel outlet.

A dispensing apparatus is for use by users to take a chamber, fill the chamber with an aerosolized vaccine or other medicament, and dispose of used chambers. A display provides instructions to encourage prompt inhalation by the user from a dispensed and filled chamber. The apparatus allows very fast administration of vaccines to large numbers of people. The aerosol dispenser apparatus detects the chamber is in correct position and delivers a pre-determined dose of aerosol. Once the dose is delivered a visual and/or audible indicator informs the user that the chamber is filled and that they can take the inhalation. The single dose aerosol chamber is optimized for efficient administration of an aerosol.

A flow component particularly for haemodialysis medical lines includes a duct having a first and a second end tubular connector coaxial to each other and designed to be connected to the line, and an intermediate tubular connector of the female luer type arranged orthogonally to the duct. A hollow elastic element substantially extends along the entire intermediate tubular connector and the body is internally configured so that, in use, the flow along the duct is partly diverted towards the intermediate tubular connector and introduced with a swirling motion along the cavity of the hollow elastic element.

A spray tip for dispensing fluids that react together includes a first lumen for a first fluid, a second lumen for a second fluid, and a dispensing cap located at distal ends of the respective first and second lumens and defining a distal end of the spray tip. The dispensing cap includes a distal end wall defining a closed end of the dispensing cap, a first spray opening formed in the distal end wall that is in fluid communication with the first lumen, a second spray opening formed in the distal end wall that is in fluid communication with the second lumen, and an external dividing wall that projects distally from the distal end wall of the dispensing cap and that extends between the first and second spray opening for forming a barrier between the first and second spray openings.

A de-agglomerator comprises: a medicament chamber comprising an inlet and outlet and having a cross-section with a substantially circular inner perimeter; a conduit in pneumatic communication with said inlet; and a blower arranged to direct airflow at dry powder medication through said conduit. Another de-agglomerator comprises: a piezoelectric transducer; a pumping chamber: coupled to said transducer through a diaphragm, and having a outlet hole: in a wall opposing the transducer, in line with the transducer axis, and arranged to be in pneumatic communication with a flow channel of said inhaler through which a user can inhale; and a housing surrounding said pumping chamber, comprising a housing inlet in a wall facing the transducer; a housing outlet in a wall facing said outlet hole and in line with the outlet hole; and being spaced from the pumping chamber by an airflow channel in pneumatic communication with the housing inlet and outlet.

Systems and methods for mixing at least two gases for delivery to the airway of a subject use a gas mixing circuit having a diffusion portion. The diffusion portion may be configured to elongate the shape of the cross-section of the path through the gas mixing circuit in a particular direction and/or orientation. As a result, the gas concentration profile of the gas mixture after the gas mixing circuit is more uniform than the gas concentration profile after the merging of multiple gases.

A device for providing respiratory gases comprises a blower configured to receive a first gas from a first gas flow path and generate a flow of a first gas provided through a first gases outlet of the blower; a second gas flow path configured to receive a flow of a second gas and provide the flow of the second gas through a second gases outlet; and a mixing chamber configured to receive a flow of the first gas from the first gases outlet and a flow of the second gas from the second gases outlet. The received gases are configured to mix in the mixing chamber to form a mixed gas. The received gases are configured to travel in a mixing flow direction in the mixing chamber towards a mixed gases inlet, wherein mixed gas exits the mixing chamber via the mixed gases inlet providing flow to a mixed gas flow path.

A humidifier for delivering humidified gases to a patient includes an inlet, an outlet, a gases flow path extending from the inlet to the outlet, a permeable wall, a liquid reservoir, and a heater. The permeable wall separates the gases flow path from the liquid reservoir. The heater heats liquid stored in the liquid reservoir to form vapour, and the vapour passes through the permeable wall to the gases flow path to humidify gases in the gases flow path. Another inline humidifier for delivering humidified gases to a patient includes an inlet and an outlet and holds a tape made of hydrophilic or hygroscopic material. The tape is pre-soaked with water and can include a heating element. The heating element heats the tape and the stored water to release the stored water as vapour and thereby humidify gases passing through the inline humidifier.

A degassing module that may be used in conjunction with a sorbent regeneration cartridge is described. The degassing module may include an air inlet port, a fluid outlet port, a gas outlet port, first and second channels located in an interior chamber, a port connecting the first and second channels, and a hydrophobic membrane positioned above the second channel. The first channel may be in fluid communication with the air inlet port and the second channel may be in communication with the fluid outlet port. In some embodiments, each of the first and second channels may have a spiral configuration.
