There is provided an aerosol generating system for heating a liquid aerosol-forming substrate. The system includes an aerosol-forming chamber, and a leakage preventer for preventing or reducing leakage of liquid aerosol condensate from the aerosol generating system. The leakage preventer may include one or more of: at least one cavity in a wall of the aerosol-forming chamber, for collecting droplets of condensed liquid aerosol-forming substrate; at least one hooked member for collecting droplets of condensed liquid aerosol-forming substrate; an impactor for disrupting airflow in the aerosol-forming chamber so as to collect liquid droplets; and a closure member for substantially sealing the aerosol-forming chamber when the aerosol generating system is not in use.

A self-contained, hyperthermic conditioning unit and selectively controllable environment for exercising. The unit comprises a base portion having a bed therein and a removable cover connected to the base portion to enclose a personal compartment within the unit. One or more heating elements provide heat to the personal compartment and one more pieces of physical exercise equipment are provided within the personal compartment.

The disclosure relates to a method and a device for obtaining a breath sample of a test person, wherein the test person inhales a droplet mist which is preferably colder than the ambient temperature. The material exhaled and/or ejected by the test person is collected as a breath sample in one or more collection vessels.

The aerosol-generating article includes a housing with a first end and a second end. The housing defining a cavity. A first volatile substrate is in a first frangible capsule, where the first frangible capsule is between the first end and a middle section of the housing. At least a portion of a pre-vapor formulation retention medium is between the first end and the middle section of the housing. The vapor-generating article is configured to be connected to an electrically-operated vapor-generating device, where the vapor-generating article is configured to allow air to be drawn through from the first end to the second end if a negative pressure is applied to the second end. The vapor-generating system includes the vapor-generating article.

The aerosol-generating article include a plurality of elements coaxially aligned and assembled within a wrapper, the article having an outlet end and a distal end upstream from the outlet end. The article includes a liquid aerosol-forming substrate, and a liquid retention medium for retaining the liquid aerosol-forming substrate. The wrapper is formed from a sheet of liquid-impervious material, the liquid retention medium being in a first element of the plurality of elements.

A device and method for treating a wound of a patient with negative pressure is provided. The device comprises a heat-assisted pump system. The pump system can be powered in part by heat derived from the patient. The pump system may be configured to be highly planar, light weight, and portable. The pump system may comprise a Stirling engine or a thermal acoustic engine.

An electronic cigarette includes a ceramic heating element having a current conducting heating member on and/or in a body of ceramic material which is impenetrable to the liquid; a liquid delivery member to deliver liquid from a liquid storage to the heating element; a battery; and an electric circuit for electrically connecting the heating element to the battery. The body of ceramic material is to contact or be in close proximity to the liquid delivery member, to vaporize the liquid when the ceramic heating element produces heat. The electronic cigarette further includes a cartomizer part, having the liquid storage and the liquid delivery member, and a battery holding part, having the battery, the ceramic heating element, and the electric circuit. In an assembled state, the cartomizer part and the battery holding part are assembled. In a disassembled state, the cartomizer part and the battery holding part are separated.

A multifunctional skin patch can be used during a treatment procedure to achieve one or more safety factors, including skin cooling, pain management, laser plume control, and/or proper application of the treatment. The multifunctional skin patch includes a transparent hydrogel layer that can be applied to a patient's skin prior to application of the treatment procedure. The treatment procedure can be conducted through the transparent hydrogel layer, and the transparent hydrogel layer (with can be pre-cooled) can cool and/or control pain within the portion of the patient's skin during and/or after the treatment procedure. In some instances, the multifunctional skin patch can also include a transparent indicator layer (covering at least a portion of the transparent hydrogel layer) with dispersed indicator particles attached thereto and/or embedded within. The indicator particles are configured to change in appearance upon application of treatment procedure through the transparent indicator layer.

A heater-cooler apparatus of an extracorporeal perfusion system comprises at least one fluid circuit (102, 104) providing a supply of a heat transfer fluid to the perfusion system, a cold storage unit (266), and a refrigeration unit (250) for charging the cold storage unit (266). The cold storage unit (266) comprises a chamber (312) containing a liquid that freezes at a temperature above that to which the heat transfer fluid is cooled by the refrigeration unit (250), and a passage through which the heat transfer fluid is conveyed, the passage extending through the chamber (312). This allows a more effective cold storage unit to be provided.

A treatment system delivers a breathing gas and frozen ice or other particles (FSP) to a bronchus of a lung of a patient in order to induce hypothermia. The breathing gas and the FSP are usually delivered through separate lumens. Clogging of an FSP lumen can be inhibited by heating and/or cooling of the lumen. The temperature of exhaled gases or a body temperature may be measured, and a controller can adjust the duration or rate at which the ice particles are delivered in order to control the patient's core temperature based on the measured temperature.
