Abstract: The present invention discloses a manual type C-shaped wire clamp operating device, includes an insulating operating rod, wherein an upper end of the insulating operating rod is provided with a threaded rod, and the threaded rod includes an upper thread and a lower thread; a wire clamp clamping device, wherein the wire clamp clamping device includes a first spring, a wire clamp seat and a floating clamping block located above the wire clamp seat, a wire clamp seat threaded hole is formed in the wire clamp seat, the wire clamp seat threaded hole is in fit connection with the lower thread of the threaded rod; a drainage wire pressing device, wherein the drainage wire pressing device includes a guide rod arranged on the wire clamp seat and a drainage wire pressing block sliding along the guide rod, and a pressing block threaded hole is formed in the drainage wire pressing block.

Abstract: Filtered, clean air can be provided via a personalized airflow to a user, to reduce inhalation of unwanted particles, bioaerosoles, and the like, while providing greater comfort than passive PPE. Various systems and methods are disclosed herein, for filtering and cleaning air via a smart, wearable device. For example, a headset in accordance with this disclosure can detect unwanted particulate matter, harmful compounds, bioaerosols, and other ambient conditions, and dynamically adjust an airflow to form an airshield that is distributed over a user's nose and mouth so as to reduce inhalation of contaminated air by as much as 70%. Various embodiments may utilize filters, disinfection modules, pressure sensors, movement sensors, ambient sensors, and contaminant sensors housed within wearable, portable devices.

Abstract: Disclosed is an air distribution control unit or a filtration/ventilation unit which is portable and/or can be mounted on or integrated in furniture e.g. as a cabinet of at the head region of a bed. The filtration/ventilation unit cleanses air from a person/patient by aspirating the person's/patient's exhalation air into the filtration/ventilation unit. To construct an at least partly isolated area around the patient, filtered air can be directed e.g. vertically out of the filtration/ventilation unit to perform an air curtain. Use of the filtration/ventilation unit reduces the risk of dissipation of air-borne diseases and health hazardous matter, and reduces the amount of air to ventilate a room with patients.
