The present invention relates to a filtering syringe, and more particularly, to an apparatus obtained by improving a syringe provided with a filter means for filtering foreign substances such as glass fragments of an ampoule, so as to prevent an injection needle or an injection flow passage from being contaminated with the foreign substances while allowing a liquid medicine to be smoothly sucked with a smaller force. The filtering syringe is configured such that the injection needle or the injection flow passage is isolated from the suction flow passage which is upstream of the filter means and in which the foreign substances may remain together with the liquid medicine, thereby allowing the liquid medicine to be sucked with a force less than that required for a conventional syringe and thus maximizing user's convenience and marketability of the syringe.

A device is provided for delivering a predetermined volume of at least one substance within a body cavity of a subject. The device contains a) a capsule for containing the predetermined volume of substances; b) a delivery end, having at least one orifice of diameter D, for placement in proximity to the body cavity; c) a valve mechanically connectable to the capsule, having at least two configurations: (i) an active configuration in which the valve enables delivery of the substances; and (ii) an inactive configuration, in which the valve prevents delivery of the substances from the capsule to the body cavity; and d) a fluid tight chamber configured to contain predetermined volume V.sub.gas of pressurized gas at a predetermined pressure, P.sub.gas. The capsule further contains at least one mixing mechanism that mixes the substances and the pressurized gas after the valve is reconfigured to the active configuration.

A device and method for converting a consumable into an aerosol with high heat without burning the consumable by packaging the consumable containing an internal susceptor inside an encasement with an induction heating element wrapped around the consumable-containing package to heat the susceptor using a magnetic field generated by the induction heating element. Combustion of the consumable-containing package is minimized by limiting air inside the consumable-containing package by coating a plurality of holes in the encasement material that melts at high temperatures. The coating may also include a flavoring.

Systems and methods for the intravascular treatment of clot material within a blood vessel of a human patient are disclosed herein. A method in accordance with embodiments of the present technology can include, for example, positioning a distal portion of a catheter proximate to the clot material within the blood vessel. The method can further include coupling a pressure source to the catheter via a tubing subsystem including a valve or other fluid control device and, while the valve is closed, activating the pressure source to charge a vacuum. The valve can then be opened to apply the vacuum to the catheter to thereby aspirate at least a portion of the clot material from the blood vessel and into the catheter.

A microwave heating method and unit for heating an aerosol-forming sample due to microwave absorption by a material of the sample and in particular for thereby releasing by or from said sample upon heating said sample at least one aerosol, in particular in a or as a inhalation, vaporizer and/or smoking product or device, in particular for medical and/or pulmonary drug delivery applications. The microwave heating unit includes (i) a sample holding and exposing unit configured to receive and hold a sample in a holding and exposing space and to expose the sample to a microwave radiation field within said holding and exposing space, (ii) a microwave radiation generating and/or releasing unit configured to release the microwave radiation field to said holding and exposing space, and (iii) an impedance matching unit configured to achieve impedance matching between the holding and exposing space and the microwave radiation field.

There is provided an attachment device for maintaining positive fluid pressure, the attachment device comprising a body having a fluid outlet port and at least two positive pressure fluid inlet ports; wherein each of the at least two positive pressure fluid inlet ports is connectable to a respective fluid source; wherein each of the at least two positive pressure fluid inlet ports is in fluid communication with the fluid outlet port; wherein each of the at least two positive pressure fluid inlet ports comprises an attachment device mechanism for selectively starting and stopping a flow of fluid from the respective fluid source to the fluid outlet port, and wherein the attachment device mechanism comprises a valve moveable between an open valve position and a closed valve position. An attachment device, connector, and method of using an apparatus suitable for a ventilator is also disclosed.

An apparatus for delivery of a flow of gases to a user, such as a respiratory therapy apparatus, is provided. The apparatus may have first and second inlets for receiving supplementary gases flows, a blower to generate the gases flow to the user, and a controller. A valve and a sensor may be provided in the second inlet. The controller may be configured to detect the disconnection of a gases source from the second inlet, and to respond by operating the valve and/or triggering an alarm. The controller may be configured to determine whether a gases flow is being provided at one or both of the inlets, and to accordingly control an operational mode of the apparatus.

A closed loop filtration system includes first and second trocars providing sealed access to a body cavity, a power supply, first and second ionizer units electrically coupled to the power supply, and a filter cartridge. The filter cartridge includes an inlet in communication with the first trocar, an outlet in communication with the second trocar, a first electrode disposed downstream of the inlet of the filter cartridge, and a second electrode disposed downstream of the first electrode. The first electrode is electrically coupled to the first ionizer unit to ionize airborne particulate matter flowing therethrough. The second electrode is electrically coupled to the second ionizer unit and configured to attract the airborne particulate matter that is ionized by the first electrode.

The present disclosure is directed to a plurality of air quality devices configured to be held in a user's mouth and configured to increase at least one of humidity and temperature and constitution of air inhaled. There are passive and active systems that allow for improved physical and lung performance.

A method is provided that includes intranasally dispensing nasal wash fluid into a nasal cavity of a subject. Thereafter, a specimen sample is collected by performing an anterior nares nasal swab. The specimen sample is tested for the presence of a virus using a lateral flow immunoassay test strip. Other embodiments are also described.
