A fluid switching valve including a first elastic tube that delivers a first fluid; a second elastic tube that delivers a second fluid; a third elastic tube having one end connected to the first and second elastic tubes; and a switching member that, by displacing a protruding portion, switches between a first state in which the first elastic tube is constricted and the second fluid is delivered to the third elastic tube, a second state in which the second elastic tube is constricted and the first fluid is delivered to the third elastic tube, a third state in which the first and second elastic tubes are both constricted and introduction of fluid to the third elastic tube is cut off, and a fourth state in which neither the first nor second elastic tube is constricted and both the first and second fluids are delivered to the third elastic tube.

A method of assembling a nozzle assembly is disclosed. The method includes: providing a nozzle member having a central passage defined by at least an inner side surface and an inner distal surface; inserting a fluid atomizer into the central passage of the nozzle member; and, with a distal surface of the fluid atomizer arranged adjacent the inner distal surface of the nozzle member, flexing legs of the fluid atomizer in a radially-outward direction for engaging each leg of the legs with the inner side surface of the nozzle member. A fluid atomizer is also disclosed. A nozzle assembly is also disclosed. A method of utilizing a nozzle assembly is also disclosed.

A veterinary subject intranasal administration device includes a first support member portion including a septum interface portion sized for insertion into a nasal passage of the veterinary subject; an actuation mechanism connected to the first support member portion; and a fluid conduit having a distal end opposite a supported end, the distal end sized for insertion into the nasal passage of the veterinary subject, the fluid conduit being flexible and configured to receive fluid from a fluid source and discharge the fluid through the distal end into the nasal passage, the distal end of the fluid conduit being unsupported and movable relative to the septum interface portion.

The disclosed apparatus, systems and methods relate to various devices, systems and methods for gently restraining an unanesthetized laboratory animal, particularly for facial recognition applications. In some applications, the laboratory animal may have been previously cannulated.

The present invention provides an intra-ruminal device comprising a body substantially impervious to rumen fluid, the body comprising a barrel, at least one outlet, and at least one matrix in the barrel, a compression arrangement within the body adapted to bias the column of matrices in the barrel to the at least one outlet, and at least one variable geometry device dependent from the body to assist numen retention, wherein the at least one matrix in the barrel comprises at least one active ingredient and at least one polymer selected from the group consisting of a non-ionic polymer and a cross-linked anionic polymer. The invention also provides a method of making and using the device.

A steam room for sanitizing people's external body parts and clothes, but also their breathing airways and respiratory tract, to reduce viral load and thereby mitigate the likelihood of spreading or contracting Viral contamination. Steam room has precise temperature and relative humidity control of a heater and mist generator, in which the mist water molecules contain an accurate concentration of a Chlorine or Ethanol based disinfectant, so that the water vapor or combined air/water mixture in the room that comes in contact with the sanitized person reaches but does not surpass the globally permitted concentration of free Chlorine for swimming pools, dressing rooms and spas. The room has thermally isolated quick doors allowing rapid entry and exit, and the signaling to guide the person when to enter, stay and breath, and exit, in the most suitable timing profile for the application.

A drug delivery pump includes a dosing chamber (16) for delivering a substance (18) therefrom, pushing apparatus, and a thermal energy source (14) arranged to cause a sufficient change in temperature in a portion of the pushing apparatus so that the pushing apparatus imparts a pushing force against the substance to cause the substance to be delivered from the dosing chamber. A controller (90) controls delivery of the substance from the dosing chamber. A thermal insulator (24) thermally insulates the substance in the dosing chamber from the thermal energy source.

The invention relates to hand-held, powered injection devices, for administering fluids, including vaccines, to animals. The invention further relates to methods of use of the powered injection device for vaccinating avian animals. Powered injection devices according to the instant disclosure are ergonomically friendly, and offer rapid and consistent dosing, particularly for avian animals.

A system for conducting inhalation studies includes an inhalation exposure chamber and an aerosol delivery line connected to the inhalation exposure chamber. The aerosol delivery line is configured to produce a bi-directional and symmetrical presentation of aerosol to the inhalation exposure chamber. A laminar flow element is configured to create an ante-chamber where complete and turbulent mixing of the aerosol occurs. A radial exhaust and the laminar flow element enable laminar flow of the aerosol through the inhalation exposure chamber.

A method of emitting light from one or more light emitting elements, the method comprising: emitting a first time period of photopic light, followed by emitting a first time period of scotopic light, followed by emitting a second time period of photopic light, and followed by emitting a second time period of scotopic light; wherein a first transition from the first time period of photopic light to the first time period of scotopic light is different compared to a second transition from the second time period of photopic light to the second time period of scotopic light, and/or wherein a third transition from the first time period of scotopic light to the second time period of photopic light is different compared to a fourth transition from the second time period of scotopic light to the first time period of photopic light or a third time period of photopic light.
