An oral treatment protective operation device, comprising a protective cover assembly and a suspension support connected thereto. The protective cover assembly comprises a transparent protective cover; the protective cover is provided with a soft sealing sleeve in butt-joint with a patient's mouth and a connector connecting a strong suction pipe; the left side and the right side of the protective cover are provided with operation windows; the opening parts of the operation windows are provided with arc-shaped sliding plates, which are provided with circular operation holes; the operation holes are connected to soft arm sleeves; a concave part is formed on the side of the protective cover facing a doctor, and an angle-adjustable magnifying lens is arranged in the concave part; and the suspension support comprises a vertical-deflection adjusting rod, a transverse connecting rod and a connecting lock sleeve, and further comprises a stay cable or a stay bar.

An pupilometer device includes a stowable breath shield for preventing transmission of respiratory particles between patient and user.

A shield assembly for providing a barrier adjacent to a patient disposed on a patient support apparatus. The shield assembly comprises a support frame defining a closed periphery and including a resilient element extending along the closed periphery to resiliently urge the support frame toward a bias frame shape. A barrier panel is coupled to the support frame and spans the closed periphery. The shield assembly may further include a base operatively attached to the support frame to selectively place the support frame in a contour frame shape. Tension in the resilient element effected by the base holding the support frame in the contour frame shape places the barrier panel in a curved configuration to define a patient accommodation space shaped to receive the patient adjacent to the base and to the barrier panel.

A suction ring for mounting close to the mouth opening of a dental patient, comprising an extraoral tensioning element. The tensioning element is realised as a suction tensioning element and forms or spans a negative pressure space with a film element. The negative pressure space extends annularly or partially annularly, and the negative pressure space has at least one suction nozzle, in particular pointing radially inwards.

A system can include a barrier configured to form a three-dimensional (3D) structure to define an interior volume and an exterior space and to mitigate fluid movement from the interior volume and into the exterior space thereby mitigating droplet, articulate, and aerosol movement in the flow path of the fluid from the interior volume and into the exterior space. The system can include a plurality of passages extending through the barrier to provide access from the exterior space and into the interior volume to perform the procedure on the patient or perform the study on the laboratory sample arranged in the interior volume. The barrier can be configured to be formed in the 3D structure to arrange a portion of the patient or the laboratory sample in the interior volume. The barrier can be external to the patient.

Apparatus and associated methods relate to an auto-coupling body waste containment apparatus (ABWCA). In an illustrative example, the ABWCA may include a dome container that may be placed over a patient's body portion. The ABWCA includes a self-supported wall defining a cavity. One or more access apertures may, for example, be provided in the wall. A physician's hands may, for example, be inserted along intersecting axes through a second and a second access aperture of the access apertures. The hands may, for example, engage a bottom rim (e.g., a rim) to retain a first aperture of the ABWCA over a body portion of a patient during an operation such that the container is automatically coupled to the body portion by the user's hands. The ABWCA may, for example, advantageously prevent body fluid of the patient from spraying on the physician when providing medical treatment to a patient's body.

Provided is a filtering facepiece respirator. The respirator includes a mask body having an anterior side portion, a posterior side portion, a middle portion, a first side portion, a second side portion, a top side portion, a bottom side portion and outer edge portions. The respirator further includes a primary port positioned at the anterior middle portion of the mask body and a detachable primary port adapter which is positioned over and engages the primary port. The respirator may further include an oxygen port and oxygen port adapter and a luer port and luer port adapter.

A mask can comprise a covering material that is sufficiently sized to extend over a mouth and a nose on a head of a wearer. The covering material can have an outer surface and an inner surface. The covering material can define an opening therethrough. At least one transparent membrane can be coupled to the covering material and cover the opening in the covering material. The at least one transparent membrane can define a hole therethrough. An elongate conduit can define an interior passage having a central axis. The elongate conduit can be coupled to the at least one transparent membrane so that the central axis of the interior passage is aligned with the hole. The mask can further comprise at least one securing element for securing the mask to the head of the wearer.

An aerosol-shielding endoscopy mouthpiece (AeroFree mouthpiece) is disclosed. The aerosol-shielding endoscopy mouthpiece includes a bite block part through which the endoscope passes and a mouth and nose-shielding part. Besides allowing for safe passage of the endoscope and respiration of the examinee, the bite block part includes a cover which is configured to mitigate splashing of aerosol and saliva through the orifice for endoscope passage during the endoscopic procedure. The mouth and nose-shielding part contains the bodily fluids and aerosols from the examinee's mouth and nose and reduces the risk of contamination at the time of removal and disposal.

The invention discloses an improved dental aerosol evacuation system equipped with a barrier cover subsystem in a dental procedure. Due to its dome-like special shape and other particular shapes, the barrier cover of the subsystem possesses a vacuum collecting capability that also physically blocks the spread of dispersed aerosols, blood components, and/or droplets during the dental procedures. At least a throughput connecting hole is connected from the curved barrier cover to the proximal end of the suction tubing of the subsystem. The vacuum collecting subsystem of the invention evacuates all or most of the collected unhealthy risk factors out of the treatment room completely for safety of patients, staff, and practitioners.
