Abstract
A photocatalytic positive-pressure medical protecting clothing for generating a positive-pressure protective air layer around human body is composed of a protective glass, a protective clothing, and a photocatalytic air-cleaning unit with power supply and photocatalytic net filter for disinfecting function.
Description
Technical field the present invention relates to a kind of medical protective garment, and the application of photocatalyst technology in medical protective garment.
Background technology is in the contaminated occasion of air, infectious disease ward as hospital, the place of spraying insecticide etc., for avoiding harmful substances in air invasion and attack human body, medical matters or workmen need dress protective garment, protective clothes such as mouth mask, it is dustproof that common protective garment mainly acts on, for bacterium, the iris action of microorganisms such as virus is little, because its protective action mainly is to be attracted on the fiber on protective garment surface by harmful substance, but the time one is long, the harmful substance that is adsorbed on the surface still can progressively be penetrated into protective garment inside, so, occasion medical matters or the workmen serious in air pollution also need dress multilyer armor, to prolong the time of harmful substance from the protective garment infiltration.For preventing that harmful substance is penetrated into protective garment inside; in the prior art; it is to utilize electric blower to charge into (filtered) gas toward protective garment inside that a solution is arranged; make the air pressure of protective garment inside be slightly larger than external pressure; impel the protective garment internal gas outwards to overflow like this, and outside (filtered) gas can't enter protective garment inside, thereby play protective effect human body; this protective garment is because air pressure inside is bigger than the outside, so be called the malleation protective garment.Though existing medical malleation protective garment is having tangible advantage aspect the obstruct pernicious gas, but imperfection also aspect practicality, mainly have the following disadvantages: 1, the sight line of existing medical malleation protective garment is finished by transparent face mask, and transparent face mask and protective garment sealing are with the isolating exterior air, when the gas that breathe to produce when the oral cavity and the body temperature of human body made the protective garment internal temperature form the temperature difference with external air temperature, the transparent face mask of general material making will haze and can't normally use.2, the electric blower of existing medical malleation protective garment generally adopts filtration of material air such as active carbon, filtration silk floss, because of this class material mainly is by the harmful substance in the suction type filtered air, and itself do not have sterilization, sterilizing function, can be so use certain hour because of adsorbing the saturated filtration that loses.For above-mentioned reasons, existing medical malleation protective garment is not widely used as yet.
Catalyst also claims catalyst, and photochemical catalyst also claims photocatalyst, and the alleged photocatalyst of prior art is meant with titanium dioxide the general name of the photosemiconductor material with photo-catalysis function that is representative.This material is under the irradiation of light; can produce free electron and hole; thereby has a very strong photooxidation restoring function; various organic compounds of oxidable decomposition and part inorganic matter; can destroy the cell membrane of bacterium and solidify the protein of virus; has very strong air-cleaning function; because photocatalyst only provides reacting environment; and itself do not participate in chemical reaction; so its action effect is lasting; photocatalyst has been widely used in air cleaning in recent years; medicine equipment; household electrical appliance; occasions such as environmental protection; the application of existing photocatalyst technology aspect medical protective garment; be that photocatalyst material is sprayed on the surface that protective garment or mouth mask etc. can be subjected to illumination; this method can make the outer surface of protective garment or mouth mask possess sterilization; sterilizing function, but for the air that passes through from the space or the side of protective garment or mouth mask just not effect.
Summary of the invention the objective of the invention is to design a kind of air conservation layer that can form a malleation around human body; do not influence the normal sight line requirement of user again, make air cleaning unit have the medical malleation protective garment that sterilization, sterilizing function can use again for a long time simultaneously.
The present invention is combined by protective glasses, protective garment, photocatalyst air purifying device.Protective glasses and existing medical protection mirror structure are basic identical, and protective glasses is connected by picture frame with protective garment.The difference of protective garment and existing malleation protective garment is to remove transparent face mask, at the eye position of head a hole that is connected with the protective glasses picture frame is arranged.Photocatalyst air purifying device and existing electric blower difference are that the air filtration mode is improved, and adopt photocatalyst filtering net, replace existing absorbent-type filtering material.
Working mechanism of the present invention is: put on protective glasses during use earlier, put on protective garment again, perforate on the protective garment head is enclosed within on the picture frame of protective glasses and is attached thereto, the air outlet of photocatalyst air purifying device is connected with the air inlet of protective garment, turn on the power switch the mini fan work that makes air cleaning unit inside, the air that purifies through photocatalyst filtering net is charged in the protective garment, because protective garment is connected by picture frame with protective glasses, the minute surface expression of protective glasses is in the protective garment outside, the protective cover of protective glasses forms a space that isolates relatively in the inner around eyes of protective garment, therefore, can not have influence on the transparency of protective glasses minute surface when human body respiration or speech at the inner gas that contains moisture content (intercepting) that produces of protective garment because of being subjected to protective cover, because (the medical protection mirror) is so protection is covered with air-vent in the inner just isolation relatively of protective garment, the effect of air-vent distributes (human body) heat in the protective cover, in order to avoid generation fog, and (human body) heat in the protective garment charges into the air-flow that produces when purifying air by (air cleaning unit) and takes away.Owing to ultraviolet lamp is housed in the photocatalyst air purifying device, (sterilization, sterilization) function and need not replacing is reduced in the photooxidation that makes photocatalyst filtering net can keep continuing.
The present invention compares with existing medical malleation protective garment, so do not influence sight line owing to adopt protective glasses to replace transparent face mask to use for a long time, because of adopting photocatalyst filtering net, air cleaning unit promptly have the function of sterilizing to avoid changing the trouble that filtering material brings again, simultaneously also reduced use cost, the medical malleation protective garment of this photocatalyst only need charge or change battery just can be used for a long time.
Specific embodiment protective glasses is the geometry that picture frame is designed to similar Sui Yuan on existing medical protection mirror basis, and it is to be convenient to be connected with protective garment that the periphery of picture frame is provided with its effect of groove.Protective garment adopts waterproof fabrics to make, open a hole that is connected with the protective glasses picture frame at the eye position of head, elastic cord is equipped with in the border in hole, its effect is that protective garment (hole) is cooperated closely with protective glasses (groove of picture frame), also worked simultaneously the effect easily of shirking, at air inlet of the back of protective garment intermediate open position (its size cooperates with the air outlet of air cleaning unit), connect a flexible duct in the inside of air inlet, the another side air outlet in air channel is located at protective garment head (top of protective glasses) position, adorns an one-way exhaust valve again below protective garment.The available following method of photocatalyst air purifying device is implemented: the plastic casing of doing a rectangle, lower opening is as air inlet, begin upwards to install dustproof filter screen, photocatalyst filtering net, ultraviolet lamp, photocatalyst filtering net, mini fan, air outlet successively in enclosure interior from air inlet, battery case, circuit board, switch are installed in the side of housing.During use, the perforate of protective garment head is enclosed within the groove of protective glasses picture frame and connects, the photocatalyst air purifying device is worn with protective garment, available belt is fixed on the back (also can make a pocket at the protective garment back and be placed on the inside) of waist, its air outlet is connected with the air inlet of protective garment, open the air cleaning unit power switch, mini fan starts and will charge in the protective garment through purifying air of photocatalyst filtering net sterilization, sterilization, when the air in the protective garment surpasses setting pressure, ooze out from one-way exhaust valve, take away the waste gas that human body respiration produces simultaneously.As with the transparent material moulding of the housing of air cleaning unit, make built-in photocatalyst filtering net can receive light from outside, also can save ultraviolet lamp.This medical malleation protective garment with photocatalyst air purifying function can be widely used in the occasion of air severe contaminations such as medical treatment, chemical industry.
