Devices and methods for delivering and filtering a gas to a wound site to enhance healing, reduce the potential for bacterial infections, lessen the need for antibiotics and to create a protective and therapeutic gas atmosphere along a treatment site. More particularly, the invention relates to a device arranged to deliver a gas to a treatment site, the device being connectable to a gas source, the device including (i) a first membrane comprising a flexible, microporous polymer body and (ii) a second membrane comprising a flexible nonporous polymer body. Outer edge portions of the second membrane are bonded to outer edge portions of the first membrane to form an interior chamber of the device, the interior chamber of the device confining introduced gas to the interior chamber such that the introduced gas flows out through the pores of the first membrane and is diffused along the treatment site.

A wound therapy device includes a wound dressing and a humidifier configured to deliver humid air to a wound site to which the wound dressing is applied. The humidifier may be a remote structure that is fluidly connected to the wound dressing applied about a patient's skin at a wound site. Alternatively, the humidified may be integrated with the wound dressing to define an integral, portable therapy device that may be worn by the patient. The wound therapy device may be a standalone wound treatment device, or may be used in conjunction with other wound treatment devices, such as, e.g., negative pressure wound therapy devices.

Devices and methods can be used to apply an adhesion promoter, for example, ozone, over the surface of the biological tissues, before and/or concurrently with the application of the cosmetics to improve the durability and/or appearance of the cosmetics on the biological tissues. The devices can include a recirculation system and/or a filter system to reduce the likelihood of the chemical being released into the atmosphere and/or to increase oxidation of the chemical generated by the device after use of the device.

A wound treatment system includes a processor coupled to sensor system(s), a power delivery system, an oxygen concentrator coupled to the power delivery system and including an oxygen outlet coupled to a restricted airflow enclosure provided by a dressing and located adjacent a wound site, and a negative pressure system that includes a negative pressure outlet coupled to the restricted airflow enclosure. The processor receives first sensor information from the sensor system(s), and uses the first sensor information to control the power provided from the power delivery system to the oxygen concentrator in order to control an oxygen flow created by the oxygen concentrator and provided through the oxygen outlet to the restricted airflow enclosure. When the processor receives second sensor information from the sensor system(s), it activates the negative pressure system to create a fluid flow from the restricted airflow enclosure and through the negative pressure outlet.

A system for the percutaneous application of a fluid to one or more surface areas of a skin. The system may include at least one of at least one compressor and at least one fan for providing compressed air. The system may also include an applicator fluidically connectable to the at least one of the at least one compressor and the at least one fan. The applicator may have at least one outlet opening through which a fluidic jet is flowable and directable onto the skin. The at least one of the at least one compressor and the at least one fan is attached to the applicator.

A device has a power source having a high voltage terminal and a low voltage terminal, an oil-free gas compressor, a first molecular sieve, multiple ionized gas generators, an outer metal pipe, an inner metal pipe, a dielectric insulating ceramic sheet, and a gas outlet pipe. The first molecular sieve is connected between the oil-free gas compressor and the ionized gas generators, and is capable of filtering out molecules in the gas except for oxygen. The outer metal pipe and the inner metal pipe are electrically connected to the low voltage terminal and the high voltage terminal respectively. The dielectric insulating ceramic sheet is mounted between the outer metal pipe and the inner metal pipe, and forms an ionizing space, which communicates with the ionizing space, with the outer metal pipe.

Heads for an aerosol container are disclosed. The head comprises a handle body having a base configured to be coupled to the aerosol container, an outlet, a flexible tube housed within the handle body. The flexible tube is configured to provide fluid communication between the container exit of the aerosol container and the outlet. And the head further comprises an elastically deformable actuator having a lever arm, and a coupling portion integrally formed with the lever arm and configured to be mounted around the flexible tube, wherein the coupling portion is further configured such that when the lever arm is deformed by a user, the coupling portion actuates on the valve body of the aerosol container. Aerosol containers having such heads and kits for treatments skin lesions are also disclosed.

The present disclosure relates to a connector device for a negative pressure wound therapy system having a connector housing, a fluid outlet connected to the connector housing, an air feeding port and an air filter and coupling means. The fluid outlet is adapted to be connected to a negative pressure source. The connector device is adapted to be engaged with a wound side connector of a wound side assembly by means of the coupling means. The wound side assembly includes a fluid removing conduit and an air supplying conduit, wherein a portion of each one of the fluid removing conduit and the air supplying conduit is connected to the wound side connector. The connector device when engaged with the wound side connector, the fluid removing conduit is fluidly connected to the fluid outlet and the air supplying conduit is fluidly connected to the air feeding port such that air ambient of the connector device can be fed to the air supplying conduit via the air feeding port and the air filter.

A therapeutic apparatus for treating damaged tissue on a limb or body of a subject includes a wearable adapted to cover and be secured to the limb or body of a subject over damaged tissue. The wearable being configured to reduce pressure on the damaged tissue and adapted to deliver one or more treatments selected from the group consisting of heat, oxygen, electrical current, and light to the damaged tissue.

Multistage vaporizers, such as for use in medical treatment systems, as well as related methods are described. In one example, a multistage vaporizer includes a first reservoir configured to hold a liquid and one or more pumping transducers positioned in the first reservoir. The multistage vaporizer also includes a second reservoir and one or more vaporizing transducers positioned in the second reservoir. The one or more pumping transducers positioned in the first reservoir are configured to generate and move droplets of a liquid in the first reservoir to the second reservoir, and the one or more vaporizing transducers positioned in the second reservoir are configured to create a vapor of the liquid in the second reservoir.
