This disclosure describes devices, systems, and methods related to a wound closure device. An example of a wound closure device includes a plurality of base members configured to adhere to a tissue site and one or more attachment members for use in combination to create mechanical tension on the edges of a wound to facilitate closure of the wound. The plurality of base members include a first base member that includes light switchable adhesive. The light switchable adhesive is configured to transition from a first state to a second state, and the light switchable adhesive has a first peel strength in the first state that is greater than a second peel strength of the light switchable in the second state. The one or more attachment members are configured to couple to two or more base members of the plurality of base members.

The invention discloses an aromatherapy humidifier, which includes a base, a shell and a cover, which are superimposed sequentially. An atomizing container is arranged on the base. A water storage tank is arranged on the atomizing container. The atomizing container and the water storage tank are contained in the shell. The water storage tank supplies water for the atomizing container and is provided with a mist channel communicated with the atomizing container. The atomizing container is provided with an atomizing assembly for atomizing water into mist and an aromatherapy assembly for volatilizing essential oil. The cover is covered on the shell and the water storage tank, the cover is provided with a spray port communicated with the mist channel and an water inlet communicated with the water storage tank, the mist and the volatilizing essential oil float through the mist channel and the spray port to humidify air.

A device comprising a housing having a handle end and a treatment end. The treatment end is configured to provide an antimicrobial treatment and a heat treatment. The treatment end comprises an applicator having an applicator surface for providing at least the heat treatment. The device includes a heat generation unit configured to heat the applicator surface in use, a source of antimicrobial agent, and a control unit operatively connected to at least the heat generation unit for controlling the heat generation unit. The device can be a hand-held device and used to apply topical treatment to a treatment area of a subject.

Brush portions are configured for use with a handheld device. The brush portion includes at least one bristle disposed on a bristle base, the bristle having an elongate first electrode, an elongate second electrode abutting the first electrode, and an insulator disposed between the first electrode and the second electrode. The first electrode and the second electrode are electrically connectable to a first voltage source and a second voltage source of the device, respectively.

Described is a method and device for dilating a tubular anatomical structure. The device and method can be useful for extracting a blood clot in an artery of a mammal by concentrically irradiating an inner wall of the occluded artery using an ultraviolet (UV) laser beam delivered by an optical fiber. Dilation results from photophysical production and release of nitric oxide from the cells lining the arterial wall when UV laser light is projected as a ring beam onto the inner arterial wall.

The nebulizer gas scavenging system includes a condenser positioned in the expiratory pathway of the breathing circuit for extracting liquid from expiratory gases and redirecting the extracting liquid to the input of the nebulizer. The system is further configured to detect the actual consumption of inhaled medication by measuring the concentration of medication in the expiratory pathway and comparing it to the initial content of medication in the aerosol of the inspiratory pathway. A more accurate determination of the amount of inhaled medication is advantageous in certain critical situations involving application of medication by inhalation.

A ventilator system includes a gas flow chamber configured to receive ventilation gas circulating in a ventilation gas pathway of the ventilator and at least one UVC lamp. The UVC lamp is configured to radiate UVC spectrum light into the gas flow chamber to inactivate pathogens in the ventilation gas. A flow sensor is configured to measure a gas flow rate of the ventilation gas and a controller is configured to receive the gas flow rate, determine an intensity based on the gas flow rate, and control power to the UVC lamp based on the intensity.

An artificial ventilation system and relative control method, the ventilation system is suitable for application to CPAP (Continuous Positive Airway Pressure) breathing helmets to provide artificial ventilation to a patient with respiratory difficulties destined for so-called “sub-intensive” therapies. The artificial ventilation system provides a fully automated ventilation and does not require frequent checks by specialized medical personnel. The relative control method allows automatic control of the entire artificial ventilation system and implements innovative control strategies and techniques.

Systems and methods for performing online extracorporeal photopheresis of mononuclear cells are disclosed. During a mononuclear cell collection cycle, blood is removed from a source and separated into a plasma constituent, a mononuclear cell-containing layer, and red blood cells, followed by the collection of a pre-product including at least a portion of the mononuclear cell-containing layer and at least a portion of the separated red blood cells. The mononuclear cell collection cycle may be repeated, followed by the production of a single mononuclear cell product using the collected pre-product(s). The mononuclear cell product is irradiated using a fixed dose of light, such that the mononuclear cell product is produced so as to have a predetermined volume and a predetermined hematocrit, regardless of the number of pre-products used to produce the mononuclear cell product. Following irradiation, at least a portion of the irradiated mononuclear cell product is returned to the source.

A hoseless CPAP system having a hoseless CPAP mask including a housing, a sealing portion extending from a back of the housing and configured to fit over a nose and mouth of a user, a fan unit provided in the housing to force air through the sealing portion to be breathed by the user, a battery provided in the housing and configured to power the fan unit, and one or more electrical contacts provided on the housing to provide charging power to the battery; and a charging base including a receiving portion configured to hold the CPAP mask therein, and one or more electrical contacts provided in the receiving portion and configured to contact the one or more electrical contacts on the CPAP mask housing to provide charging power to the battery.
