The invention involves a folding patient transfer apparatus with a material top layer and a material bottom layer. A plurality of inserts has handhold openings that are formed in the inserts that are positioned between the material top layer and the material bottom layer utilizing a sewn plurality of insert seams. The seams form enclosed material chambers containing the inserts. The materials can be disposed of due to contamination; however the inserts can be sterilized reducing hospital waste and cost. The apparatus is configured to slide and / or lift and / or carry a patient from a non-planer surface to a second planer or non-planer surface.

A system for the sterilization of hospital waste, comprising a triturator that includes a hermetic cover, a hopper and toothed drums; an auger feeder to transport the triturated waste and comprising nozzles that blow steam into the waste; a high-temperature pressurized steam generator; an airtight sterilization chamber with microwave generators and with an inner stirrer, the sterilization chamber comprising a gate at the top, a gate on one side or in the front, and a stirring device for mixing the contents of the chamber. During the whole process the waste is completely insulated from the external environment. A central unit controls and supervises the operation of all the electric, electronic and mechanical parts of the system, which can be fit into a modular container for easy transportation.

An infectious waste treatment system uses a chlorine dioxide based liquid disinfectant generated from combining precursors comprising sodium chlorite, acid, and bleach. The waste is ground into small pieces and soaked in the liquid disinfectant. The chlorine dioxide is generated by combining dilute aqueous precursors with a flow of the liquid disinfectant into a circulation pump. A preferred set of precursors comprises an approximately 25 percent aqueous sodium chlorite solution, an approximately 12 percent to approximately 50 percent citric acid solution, and an approximately 12 percent industrial bleach (sodium hypochlorite) solution such as Clorox® bleach. A continuous gas monitoring system measures the concentration of chlorine dioxide in the liquid disinfectant and commands the chlorine dioxide generator to generate chlorine dioxide when necessary.

The invention relates to a hospital wastewater purification treatment system. The system comprises a grid, an adjusting disinfection tank, a coagulation pool, a primary precipitation pool, a hydrolysis acidification pool, an aerobic biological filter tank, a secondary precipitation pool, deep oxidation equipment, a sludge pool and a recycling water storage tank connected mutually; the grid is used for removing solid impurities; the adjusting disinfection tank is used for accumulating original wastewater discharged by various wastewater sources; the coagulation pool is used for adding and mixing a coagulant and a coagulant aid; the primary precipitation pool is used for precipitating precipitable substances of wastewater in the precipitation pool; the hydrolysis acidification pool is used for biodegradation in an anoxic state; the aerobic biological filter tank is used for converting organic molecules into inorganic molecules through biological action in an aerobic state; the secondary precipitation pool is used for precipitating newly generated water and original precipitable substances in the aerobic biological filter tank; and the deep oxidation equipment is used for oxidizing residual organic matters in the water which are different for biological treatment into inorganic molecules. The system has high purification degree; and outlet water can be used as recycled water for use.

The invention discloses a hospital air purification device which is convenient to install and can purify air in wards. The hospital air purification device comprises a filtering box body; openings areformed in the two ends of the filtering box body; a filtering plate is arranged at an opening in one end of the filtering box body; a sealing cover with a vent hole is arranged at the opening in theother end of the filtering box body; and an air draft device, an ultraviolet disinfection device, a disinfection device and an activated carbon filter element are sequentially arranged in the inner cavity of the filtering box body from the end provided with the filtering plate to the other end. The hospital air purification device comprises the filtering box body, maintenance is convenient, the service life is prolonged conveniently, aerosol-infected diseases can be prevented from being spread, and environmental pollution caused by hospital waste gas emission is avoided.

The invention discloses a hospital waste gas treatment device and method which can sterilize and disinfect waste gas exhausted by a hospital and can prevent the hospital waste gas from carrying viruses, disease treatment bacteria and fungi. The hospital waste gas treatment device comprises an air suction pipe, a U-shaped ultraviolet sterilization pipe, an exhaust fan, a first filter, a booster fan, a disinfection tank and a second filter. The hospital waste gas treatment method comprises the steps that S1, the air volume of an exhaust fan is adjusted to enable the air volume in an air suctionpipe to be 5-15 m <3> / min; S2, the wavelength of an ultraviolet lamp is controlled to be 250-270 nm through an ultraviolet lamp controller; S3, a booster fan is adjusted to enable the air pressure torange from 30 pa to 80 pa; S4, 84 disinfectant with the effective chlorine concentration of 1000 mg / L is added into the disinfection tank; and S5, a heating device is arranged at the bottom of the disinfection tank, so that the temperature in the disinfection tank is 30-45 DEG C. By adopting the hospital waste gas treatment device and method, the risk of disease infection caused by hospital wastegas can be effectively reduced; the purification effect can be effectively improved; and the hospital waste gas treatment cost is reduced.

A sharp cutting object disposal device provided with means for automatic unscrewing of venopuncture needles and the like, consisting of a tube to which a pair of motors or a gear wheel are fixed, the wheel which, actuated by a geared part that upon sliding on the gear wheel, will cause the rotation of the latter and in turn, this gear wheel will move several gears which will make two cylindrical and solid contacts turn, carrying out the disposal of the needle by means of friction plus the passing of electric current, provided with a conduit inside for exhaust of gases produced by melting the needle, without needing ventilators or any other forced air system, in addition to having another tube for separating the needle from the “screw-on” type syringe during the same needle disposal operation, the inside of the drawer having a housing recipient for the needle wastes, and another recipient incorporated inside the container for housing the plastic needleless syringes or non-sharp hospital wastes, and inside this container, there is an ozone or ultraviolet valve for sterilizing the needles.

The waste disposal system disclosed herein includes a chamber operated at high ampere and low voltage, the chamber configured to inject smoke on a stream of free radicals. In one implementation, the stream of free radicals is generated from a plasma igniter and the smoke is generated from waste products, such as hospital waste products.
