The invention relates to a patient interface comprising a plenum chamber, a seal-forming structure, and a positioning and stabilizing structure, as well as the method of operating the patient interface. The patient's interface is configured to leave a patient's mouth uncovered or if the seal-forming structure is configured to seal around a patient's nose and mouth, the patient interface is configured to allow the patient to breath from the ambient in an absence of the flow of pressurized. The positioning and stabilizing structure includes headgear, and the seal-forming structure and at least a portion of the headgear is formed from a one piece construction of textile material. In another embodiment, the seal-forming structure and/or the positioning and stabilizing structure includes an adaptive portion that adjusts based on usage conditions. In another embodiment, the positioning and stabilizing structure, the seal-forming structure and/or the plenum chamber includes and/or is formed of a textile material, and the textile material includes at least one magnetic thread constructed of magnetic material to provide a magnetic interaction between a first part of the patient interface and a second part of the patient interface. In another embodiment, a stiffener is coupled to the plenum chamber, the seal-forming structure, and/or the positioning and stabilizing structure. In another embodiment, at least one of the plenum chamber and the seal-forming structure includes a textile material; and wherein the textile material includes a surface structure that limits adhesion of debris. A UV cleaning receptacle of the patient interface is also disclosed.

Methods, systems and devices for reducing anxiety, including increasing relaxation and/or calm. In some variations these methods may include reducing anxiety, increase relaxation and/or calm by non-invasive temperature regulation of the frontal cortex prior to and/or during sleep. The subject may have an anxiety disorder, or may not have a diagnosed anxiety disorder.

An electric injection device at least comprises an outer case, a drive mechanism, a transmission mechanism, a linkage mechanism and a push mechanism. The drive mechanism, the transmission mechanism, the linkage mechanism and the push mechanism are all assembled in the outer case, and the drive mechanism is used to drive the transmission mechanism. The transmission mechanism can transmit power to rotate a push block regularly and drive a brake end of the linkage mechanism continuously. The push mechanism comprises at least a pushing shaft and a pushing element. The brake end can continuously push the pushing element, and the pushing element propels the pushing shaft to further push a syringe assembled on the outer case, so as to use electric injection instead of manual injection to complete the syringe.

A prosthetic device includes a flexible interface configured to conform to a residual limb of a user, a prosthetic socket including an outer shell more rigid than the flexible interface and positioned external to at least a portion of the flexible interface, and one or more vibrational devices placed in connection with the flexible interface to impart vibration to the residual limb.

A device is provided for the self-administration of cannabinoids. The device includes a container having an opening on a first end thereof, a cap which releasably engages said first end of said container, and an assembly, including first and second modules, which is removably placed inside of the container. The first module includes a first element equipped with first and second threading, a receptacle for said solid medium, said receptacle being equipped with at least one surface feature which slidingly engages said first threading, and a solid medium which is seated in said receptacle and which contains at least one cannabinoid. The second module is equipped with a filter and has a first threading disposed on a first terminal portion thereof. Various accessories may be releasably attached to the container or assembly. Methods of using the device are also described.

A therapeutic vaporizer inhalation bag attachment system with an integrated valve is disclosed. The attachment system includes a body having a lumen extending between the two openings of the body, a bag coupling, and a valve positioned within the lumen. A method of using the inhalation bag attachment system is also disclosed.

Provided are a brain stimulation system, method, apparatus and storage medium based on artificial intelligence. The system includes: a plurality of brain stimulation terminals and a cloud platform. The cloud platform is configured to, with artificial intelligence algorithm especially machine learning and deep learning, generate multi-dimensional psychological big data using physiological data and psychological state evaluation parameters gotten from the plurality of brain stimulation terminals and established models of algorithm for disease diagnosis. The brain stimulation terminal is configured to analyze the physiological data and psychological state evaluation parameters of a target subject, measure a mental state of the target subject, obtain brain stimulation parameters required for the target subject according to the mental state, and generate corresponding non-invasive brain stimulation for the target subject according to the brain stimulation parameters based on the multi-dimensional big data through the artificial intelligence algorithm.

Devices for delivering a controlled concentration of an agent are provided. The device includes a reservoir for the agent and a flow control portion operably connected to the reservoir. The device also includes a valve for releasing the agent from the flow control portion and a pump for flowing air to mix with the agent released by the valve and for flowing the agent and air mixture out of the device. Methods of delivering a vaporized agent to a subject are also provided. The methods include storing a liquid agent in a reservoir of a device and flowing the agent into a flow control chamber to change the agent to a gas. The methods also include mixing the agent in gas form with air and flowing the agent and air mixture out of the device to be delivered to a subject.

An electronic vapor provision system includes a vaporizer for vaporizing liquid for inhalation by a user of the electronic vapor provision system; a power supply for supplying power to the vaporizer to vaporize the liquid in response to a user activation of the device; and a control unit configured to estimate a user's expected activation duration and cause power to be supplied to the vaporizer for a period of time shorter than a user's activation duration.

Apparatus is disclosed for ventilation using an airbag, which may also be operable manually. The apparatus comprises: means providing or penetrable to form an aperture in the airbag; retractable means provided separately from the airbag, for extending in the airbag; fixing means for fixing, by an operator, an end of the retractable means to the airbag via the aperture; actuation means, for repeatedly retracting the retractable means at least partially through the aperture in the airbag to collapse the airbag, and for enabling expansion of the airbag to an expanded state; and connecting means for connecting the actuation means to the airbag and for preventing environment egress of gas from within the airbag between the aperture and the actuation means.
