A personal respiratory isolation system (PRIS) provides a personal, negative pressure environment for a patient or user that reduces contamination and spread of pathogens exhaled by the patient into the environment. The PRIS includes an enclosure to receive the patient's head (such as a hood and a drape) and a negative pressure source which draws ambient air into the interior of the enclosure and draws air within the enclosure's interior (including the exhalations of the patient, including any contaminants and/or pathogens) out of the enclosure via a fluid port into a container for biohazard processing or disposal. The PRIS may allow positive air pressure therapeutic treatments to be delivered to the patient within the negative pressure environment, and the PRIS may maintain a constant pressure within the interior of the enclosure. The PRIS may include a transparent, hinged face shield for ease of patient observation and/or access.

A screen cover device and an air-cleaning device configured to be used together with such a screen cover device, wherein said screen cover device is configured for holding at least one disposable screen cover which when in use, is configured for covering at least a substantial part of an air outflow area of a screen of the air-cleaning device, wherein said screen cover device is provided as an attachment to the air-cleaning device and comprises: at least one disposable screen cover; and a first unit which is configured for keeping the at least one disposable screen cover when not in use and which is configured to be mounted to the air-cleaning device.

Embodiments described herein provide systems and methods for protecting doctors and others from pathogenic microorganisms aerosolized during surgical and other procedures on patients. The systems and methods generally operate by forming a partially-enclosed chamber around the patient's face during the procedure. A facial adapter and facial shield isolate a portion of the patient's face from the surrounding environment. The partially-enclosed chamber is connected to a vacuum source that brings the pathogenic particles through a filter, which further decreases the number of pathogenic particles expelled into the environment.

The present invention relates to an endoscopic treatment instrument, and more particularly, to an endoscopic treatment instrument including a detachable end-effector and a contamination prevention cover. The endoscopic treatment instrument includes an end-effector for performing treatment in the endoscopic surgery or an endoscope treatment, a connection section being detachably coupled to an end of the end-effector, and a contamination prevention cover being coupled to the connection section or the end-effector and surrounding a portion of an outer peripheral surface of the connection section so as to prevent contamination of the connection section. According to an embodiment of the present invention, since only the end-effector is separable for replacement and the cover is formed to protect a control unit, it is possible to prevent cross infection between patients caused by the contamination of the end-effector and the control unit.

An airborne pathogen extraction system that provides for continuous airborne pathogen particle extraction from a specifically targeted area in a room or a specifically targeted area proximate to a user. The pathogenic particles are filtered and/or disinfected before the air is returned proximate to the originating location, or are directed an area away from the user(s). The airborne pathogen extraction systems and methods lower the chances of contagion or infection from airborne pathogens, such as viruses.

Disclosed are medical devices for surgical procedures, especially procedures that involve the manipulation of surgical instrument end effectors close to the skin surface at an incision site. In accordance with some embodiments, an instrument access device is configured to couple to a wound retractor at a distal end of the device and to receive a multiple instrument entry guide in a port at the proximal end of the instrument access device, with an envelope between the distal and proximal ends defining a sealed cavity for maintaining insufflation pressure. Various embodiments provide means for rotating an assistant port in the envelope about a port that receives the instrument entry guide without twisting the envelope. Also disclosed are various envelope shapes. Also disclosed is an instrument entry guide that aligns surgical instrument shafts.

A tissue cutting device that is especially suited for neurosurgical applications is disclosed and described, as well as alternative systems for tissue preservation and transport. The cutting device includes an outer cannula in which a reciprocating inner cannula is disposed. A tissue collector is also provided and is in fluid communication with the lumen of the inner cannula. A temperature control sleeve may be disposed around the tissue collector to control the temperature of the tissue samples. A preservation system may be supplied that is configured to deliver fluids to tissue samples in the tissue collector. A fluid supply sleeve may be disposed about the outer cannula and is selectively positionable along the length of the outer cannula.

A collection device (1) for minimising dispersal of pathogens into the environment during insufflating of the peritoneal cavity (12) of a subject (3), and which are entrained in insufflating gases and other gases escaping through an incision (8) in the abdominal wall (9) of the subject (3), through which a trocar is entered into the peritoneal cavity (12) comprises a patch (5) supported on a support framework (30). The patch (5) terminates in an outer peripheral portion (20) with a pressure sensitive adhesive (21) coated thereon for sealably securing the outer peripheral portion (20) to the abdominal wall (9). A central access opening (24) formed in the patch (5) tightly and sealably engages the trocar (10). With the trocar (10) extending through the access opening (24) of the patch (5) and with the patch (5) bonded by the pressure sensitive adhesive (21) to the abdominal wall (9) of the subject, the patch (5) defines with the trocar (10) and the abdominal wall (9) of the subject an annular collection chamber (17) for collecting insufflating and other gases leaking through the opening (8) in the subject. An outlet port (25) extending from the patch (5) and communicating with the collection chamber (17) is connected through a filter (29) to a vacuum system (27) for drawing gases from the collection chamber (17) where they are filtered in the filter (29) for removing pathogens therefrom, and clean filtered gases are dispersed into the atmosphere from the vacuum system (27). Other access devices and apparatus for collecting and filtering insufflating gases and other gases leaking through an incision formed in the body of a subject or through other body orifices are also disclosed.
