A conduit for a breathing circuit includes a heater associated, at least in part, with a hydrophilic layer. The purpose of the heater is to evaporate any condensed liquid collecting in the conduit, which is first sucked up by the hydrophilic layer. The heated wick reduces the risk of collected water being passed to the patient and causing choking fits or discomfit. It is preferred that the heated wick lies freely in the conduit to settle at low points in the conduit where condensation may collect.

A breathing circuit having a semipermeable membrane, an outer cage, and optionally an inner cage. The semipermeable membrane contains a poly(tetrafluoroethylene) membrane and a graphene anti-bacterial compound. The semipermeable membrane is affixed to the outer cage; optionally between the inner cage and the outer cage. Breathing circuits and breathing systems may contain such a cartridge.

A delivery device for and a method of delivering gases to the nasal airway, in particular therapeutic gases and gases in combination with active substances, either as powders or liquids, for enhanced uptake of the active substances.

A device 10 for providing a breathing gas stream, which contains a therapeutically active substance, for the mechanical respiration and/or mechanical breathing assistance of a patient, wherein the device 10 has at least one first line 21, through which a first gas stream 31 flows during the operation of the device, and wherein the device 10 has at least one second line 22, wherein the first line 21 and the second line 22 have a common section 13, and wherein the first line 21 and the second line 22 are connected to one another by a water vapor-permeable membrane 24 in the area of the common flow section 13, the present invention provides for a second gas stream 32 to flow through the second line 22 during the operation of the device.

The present invention provides a multi-functional masking assembly having a humidity adjusting function, and having a sheet module provided on the inner side surface of the mask worn to cover the nose and the mouth of the face, wherein the sheet module is located on the cheek parts of the face, and water is supplied to the sheet module so as to supply humidity to the nose and the mouth of the face and to adjust humidity around the nose and the mouth while the mask is worn, thereby: preventing a cold, dryness due to the air during air conditioning, and inhalation of polluted air, yellow dust, fine dust, and the like caused by air pollution while increasing respiratory health; and enabling people of all ages and genders to easily use the mask. The multi-functional masking assembly with humidity control includes a mask (10) having loops (11) provided on both ends thereof and hung on the ears of an user, or female and male coupler members (12a, 12b) provided on both ends of the mask, wherein the female and male coupler members (12a, 12b) are removably coupled to each other; a sheet module (20) located on cheek portions of an inner face of the mask (10); and a water supply member (30) configured for supplying water to the sheet module (20).

A droplet delivery device and related methods for delivering precise and repeatable dosages to a subject for pulmonary use is disclosed. The droplet delivery device includes a housing, a reservoir, and ejector mechanism, and at least one differential pressure sensor. The droplet delivery device is automatically breath actuated by the user when the differential pressure sensor senses a predetermined pressure change within housing. The droplet delivery device is then actuated to generate a stream of droplets having an average ejected droplet diameter within the respirable size range, e.g, less than about 5 m, so as to target the pulmonary system of the user.

An atomizer for an inhaler includes a housing, a gasket, a liquid absorbing sheet, a wick, and an atomizing element. The housing includes a first housing and a second housing, the first housing and the second housing form a liquid reservoir therebetween for storing liquid. The gasket is sleeved on the first housing, the gasket defines a liquid conducting hole in communication with the liquid reservoir. The liquid absorbing sheet is sleeved on the first housing in contact with the gasket, the liquid absorbing, sheet is configured to absorb the liquid in the liquid reservoir via the liquid conducting hole. The wick is in contact with the liquid absorbing sheet and configured to draw the liquid from the liquid absorbing sheet. The atomizing element is fixed to the wick and configured to atomize the liquid in the wick.
