The present disclosure is directed to improved multi-suction dental devices, assemblies, systems and methods and of using the same. The multi-suction dental devices can be configured to suction both liquids and aerosols during dental procedures. Each multi-suction dental device can comprise at least one low-volume evacuation (LVE) suction pathway and at least one high-volume evacuation (HVE) suction pathway.

Apparatus, system, and methods are provided for reducing infectious agents at a sterile site by preventing infectious agents from coming into contact with the sterile site. A barrier is produced for infectious agents that may come in proximity or otherwise communicate with the site. The apparatus is configured to create a void-free barrier in which infectious agents are reduced with minimal exposure of potentially harmful effects of the barrier to the sterile site, objects, or users of the apparatus.

A surgical drape for preventing surgical site infections during surgery includes an emitter sealed air tight to the drape. The emitter includes an inflatable receiver portion and a terminal outlet distributor fluidly continuous with the receiver portion. The receiver portion inflates on receiving a sterile gas flow from a source of sterile gas. The terminal outlet portion conditions the received sterile gas and emits it as a unidirectional coherent non-turbulent flow field of essentially sterile gas into ambient air in the operating room substantially anatomically levelly at least immediately past the incision while keeping the gas essentially sterile. An embodiment is for use in surgery on an extremity of the patient and another embodiment is for use in surgery on an anatomical part that is not an extremity.

A diffuser for use with a wound retractor and configured to deliver gases includes an interface tube for connecting to a gases supply and a diffuser interface positioned at a proximal end of the interface tube, the diffuser interface configured for delivering gases received from the gases supply through the interface tube, and the diffuser interface comprising a diffusion mechanism configured to deliver gases in a diffusion direction. A wound retractor with an integrated diffuser is also disclosed. The wound retractor includes an upper ring, a lower ring, a sleeve extending between and connecting the upper ring to the lower ring, and an integrated diffuser interface having a gases inlet and a diffusion mechanism.

A device and a method of making and using the device for preventing sedimentation of airborne particles on a surface. The device includes a pad comprising with top surface, where openings are formed in the top surface, where a plurality of nozzle is situated in the openings such that a portion of the nozzle is an outlet for directing a stream of gas in an essentially perpendicular direction away from the top surface. The device also includes a hose connected to the nozzle such that the hose supplies the nozzles in the pad with the gas and a conditioning source that brings the gas into the hose after cleaning it. The flow requirements are automatically adjusted by the system (e.g., based on characteristics of the particle load).

A medical instrument tray for supporting medical instruments and connecting to a medical vacuum hose and evacuating gases and debris from a procedure area to reduce spread of airborne bacteria, viruses, or other contaminates comprises an upper surface and a laminar air flow suction device. The upper surface supports the medical instruments. The laminar air flow suction device extends below the upper surface and comprises a first opening and a second opening. The first opening is configured to connect to the medical vacuum hose and has a first opening width. The second opening has a second opening width that is wider than the first opening width.

A microenvironment of a biological body is controlled, and more particularly, is measured, changed, and monitored with respect to temperature, pH level, moisture and other tissue parameters of a region of the body while, optionally, administering a therapeutic agent to that region.

An intraocular injection system for injecting a substance into an eye globe of an animal or human eye, the system comprising an injection device with a piercing member for injection of the substance into the eye globe, the intraocular injection system providing an automated piercing of the eye globe by the piercing member. The system further comprises a robotic manipulator carrying the injection device, the robotic manipulator adapted and configured to move the injection device to a pre-injection position, a detection device adapted and configured to detect a position of a patch placed onto the eye globe and to control the robotic manipulator to move the injection device to the pre-injection position, the pre-injection position being based upon the detected position of the patch on the eye globe.

A system, method, and air purification device. Air is taken in from an environment into the air purification system. The air is treated with vacuum ultraviolet radiation in a first reaction chamber to generate irradiated air. The irradiated air is treated with ultraviolet-C radiation in a secondary reaction chamber to generate purified air. The purified air is emitted back into the environment from the air purification system.
