The present invention is directed to a system and method for photoeradication of microorganisms from a target. The method includes the step of obtaining test data for a plurality of experiments each of which comprises irradiating test microorganisms with a plurality of light pulses having a wavelength that ranges from 380 nm to 500 nm. The light pulses have a plurality of pulse parameters (peak irradiance, pulse duration, and off time between adjacent light pulses) and are provided at a radiant exposure that ranges from 0.5 J/cm.sup.2 to 60 J/cm.sup.2 during each of a plurality of irradiation sessions. The test data comprises a survival rate for the test microorganisms after irradiation with the light pulses. The method also includes the step of analyzing the test data to identify the pulse parameters for the light pulses and the radiant exposure for each of the irradiation sessions that result in a desired survival rate for the test microorganisms. The method further includes the step of irradiating the microorganisms of the target with light pulses having the identified pulse parameters at the identified radiant exposure for each of the irradiation sessions so as to photoeradicate all or a portion of the microorganisms.

An endotracheal tube airway patency system and method are provided. The system includes an endotracheal tube having a tube body having a proximal end, a distal end, an inner surface, a distal opening disposed at the distal end of the tube body, a proximal opening disposed at the proximal end of the tube body, and an airflow-effacing surface disposed within the tube body. The airflow-effacing surface includes a telescoping inner sleeve configured to be removed from the endotracheal tube body. The system further includes a tool for removal of the telescoping internal sleeve from the endotracheal tube body. The tool includes an elongated body having a proximal end and a distal end; a handle located at the proximal end of the elongated body; and at least one extension member disposed at the distal end of the elongated body. The at least one extension member is configured to couple to the telescoping internal sleeve for removal of the telescoping internal sleeve from the endotracheal tube body.

A respiratory expellant containment pad including a base layer and a containment layer on a first side of the base layer. The containment layer is configured to contain respiratory expellant from a wearer of the containment pad. An adhesive layer on a second side of the base layer is opposite to the containment layer.

The present invention provides an apparatus for detection of ventilator associated pneumonia (VAP) in a patient, the apparatus comprising: an endotracheal tube; at least two non-selective electrode contacts located in proximity to each other within the endotracheal tube, the contacts lacking any structural feature or component that particularly recognizes a chemical or biological species; an electrical subsystem that is capable of generating, receiving and processing electrical signals; wiring for connecting each of the electrode contacts with the electrical subsystem; and tubing for insulating the wiring from any sputum material that is introduced into the endotracheal tube by the patient.

An anti-shadowing virus irradiation and deactivation device comprised of air chambers having multiple ultraviolet “C” light sources, with a selectable recirculation path to harness ozone gas produced, and a system to neutralize said ozone gas upon exit.

A patient airway dome including an adjustable frame having a hinge such that the hinge allows the frame to adjust between an erected position to create an airway dome and a collapsed position that allows the frame to lay flat, a dome covering located over the retractable frame, a suction port which is connected to a conventional device in order to provide negative pressure to patient airway dome, and an arm access assembly operatively connected to the dome covering, wherein the arm access assembly includes an opening in the dome covering and a closure assembly located adjacent to the opening.

A filtered face mask apparatus for CPAP applications can include a body, an inlet port, a mouth portion having a mouth exhaust port, a nose portion having a nose exhaust port, a plurality of adjustable straps, a seal, a mouth exhaust filter disposed over the mouth exhaust port, a nose exhaust filter disposed over the nose exhaust port, and an intake filter disposed over the inlet port. The inlet port may be configured for attachment to a gas supply tube that is attached to a CPAP device on the other end. The mouth exhaust filter, nose exhaust filter, and intake filter may each comprise a N95 or N99 material configured to block the passage of pathogens. A disposable filter patch and a method of operating a positive airway pressure device are also disclosed herein.

An ultraviolet-C respirator mask that filters and destroys viruses by means of a HEPA type filter and a plurality of UVC LEDs projected on the filter. The filter element is worn on the garment of the user by means of an integral apparel clip and connected to the face mask through a breathing hose. This configuration allows easy replacement of the HEPA filter element and/or the facemask for considerations of hygiene. Filter element life is increased due to location further from contaminated field. Hygiene for the user is improved due to the collecting media being further from the user's face.

A chamber for placement over a patient while allowing medical personnel to perform various medical procedures releasing virus, bacteria, or other contaminants, such as tracheal intubation, on the patient, including a frame forming and supporting two sidewalls and a curved center portion extending between the sidewalls of a transparent body, wherein the body includes at least one access hole, and wherein the chamber surrounds the patient's head and one of the sidewalls deforms around the patient's body in order to capture and exhaust any of the virus, bacteria, or other contaminants released by the patient during the medical procedure. A method of using the chamber of to perform a medical procedure on a patient releasing virus, bacteria, or other contaminants.
