Arrangements for capturing aerosol during dental procedures include an extraoral suction device and a blower arrangement to induce an airflow zone to push aerosol to the suction device. Blower arrangements can include plenums in the form of a tube, or a face mask, or attached to safety glasses. Extraoral suction devices can be wearable in the form of appliances to be fitted onto either the patient or the dental professional. Improved extraoral suction devices can include a screen secured to a nozzle of the device.

An electronic mask with negative pressure includes a mask body, the mask body is provided with a negative pressure cavity, the negative pressure cavity covers mouth and nose, and at least one fan for forming negative pressure in the negative pressure cavity is provided, the power plug of the fan is connected to a control circuit, a first filter device is set to cover the fan; when the fan starts, the air is filtered and evacuated to outside. During the exhaust process, the water vapor in the negative pressure cavity is also discharged, which can effectively reduce the humidity in the negative pressure cavity to ease dyspnea of patients with respiratory diseases and will not increase the burden of breathing. The negative pressure design makes the air exhaled by the human body must be filtered before being discharged without leaking through the gaps of the mask. If the patient wears the mask, it can effectively prevent the spread of viruses or bacteria.

The present disclosure relates to a vehicle-type mobile infectious disease clinic, and more particularly, to a mobile infectious disease clinic, which is a vehicle-type mobile infectious disease clinic, that allows a test subject to be tested by a healthcare provider using an infectious disease test kit while exposure of the body parts is minimized and the healthcare provider and the test subject are isolated in the vehicle-type mobile infectious disease clinic, that performs sterilization of an infectious disease using an ultraviolet C (UV-C) lamp to reduce the time taken for disinfecting the clinic, and that allows the light radiation intensity of the UV-C lamp to be adaptively adjusted according to the body temperature of the test subject.

A collapsible air isolation apparatus is disclosed. The apparatus may include a collapsible frame including a base and a set of rigid panel elements at least partially enclosing a volume of space, where the set of rigid panel elements is foldably hinged to at least one of the base or another of the rigid panel elements, and where at least one panel of the set of rigid panel elements comprises an open space for mounting a motor for moving air. The apparatus may include the motor for moving air configured to create a negative pressure within the volume of space of the collapsible frame.

A negative pressure room with a safety management system according to an embodiment of the present disclosure includes an interior space being under negative pressure and is provided in a movable form, so that the negative pressure room can be constructed promptly and economically in the event of a spreading infection, thereby enabling rapid and efficient quarantine treatment and observation of patients with confirmed and suspected infections, the negative pressure room is isolated from a general ward, thereby preventing the possibility of further infection to other patients or medical staff, and real-time monitoring whether negative pressure is appropriately generated in the interior space, air quality in the interior space, and the state of an isolated patient is enabled.

The present disclosure provides an isolation unit to protect uninfected persons from a patient infected with a respiratory disease during a use case. The isolation unit generally includes a frame and cover configured to form an enclosed space surrounding the head, neck and shoulders of the patient, the enclosed space containing air and a fan/filter system in fluid communication with the enclosed space and which includes a vacuum to create a negative pressure within the enclosed space to withdraw air in the enclosed space to the fan/filter system and a filter to remove any contaminants in the air.

A device and method for preventing the spread of a communicable disease during a close proximity services session is provided. The method includes assembling a device to a face cradle of a massage table prior to the close proximity services session, wherein the device captures one or more respiratory droplets excreted by a client during the close proximity services session. The device includes a closed sidewall, an open sidewall, a top portion mechanically connected to the closed and to the open sidewall, wherein the top portion includes a securing means for securing the top portion to the face cradle and a bottom portion mechanically connected to the closed sidewall.

A pathogen containment system for use during healthcare procedures is disclosed, comprising a flexible tubing dimensioned to extend around a user's mouth, the flexible tubing including a first end and a second end. A connector includes a central portion including a first side fittingly engaged with the first end of the flexible tubing and a second side fittingly engaged with the second end of the flexible tubing. An attachment port is positioned perpendicular to the central portion, the attachment port is in fluid communication via a vacuum tubing to a vacuum suction unit. A plurality of intake ports are provided on the flexible tubing to permit air to be drawn therethrough via the vacuum suction unit. The air intake ports capture a contaminant emitted from the user's mouth or the user's nose.

A chamber for placement over a patient while allowing medical personnel to perform a medical procedure on the patient releasing virus, bacteria, or other contaminants, including a frame forming, supporting, and operatively integrated within a transparent body including a supported arch, an unsupported arch, and a top shield extending between the supported arch and the unsupported arch, wherein the body includes at least one access hole, and wherein the chamber surrounds the patient's head and the unsupported arch deforms around the patient's body in order to capture and exhaust any virus, bacteria, or other contaminants released by the patient during the medical procedure through negative pressure. A method of using the chamber of to perform a medical procedure on a patient. Methods of preventing exposure to waste anesthetic gas released from a patient after surgery, and preventing exposure to ultrafine particles and volatile organic compounds during 3D printer use.
