For its particle diameter of the coronavirus as the SARS virus is 70-200nm, spherical in shape or oval, has pleomorphism, with aerosol (droplet nuclel) state propagation, aerosol is the academic title of suspended particulates, it comprises moisture content, pollutant, reaches microorganism etc., therefore than the big hundred times of virus itself.The following aerosol particle thing of 3 μ m is " a morbific guided missile ".Virus is propagated with mode such as contact through the spittle, and at room temperature can survive 24 hours at least in the common plastics surface, can survive in patient's kenosis 4 days, and the article of crossing by contact patients also can infect.So use acetone; 10% formaldehyde and paraformaldehyde solution; 10% liquor natrii hypochloritis; It is essential that the mixed solution of 75% ethanol and 2% phenol etc. is done the water-bath sterilization.In addition, the gas path pipe mouth should be established the isolation filter membrane, and gas can pass through during operate as normal, and during cleaning and sterilizing, cleaning, disinfectant solution can not immerse respirator, but microorganisms such as essential obstruct virus.
Present embodiment shown in Figure 1 is installed in the respirator each several part in the seal box 1 and realizes, respirator has: by air pump 2, air accumulator 3, oxygen regulating valve 4 and drive circuit 15 thereof, vent valve 5 and drive circuit 8 thereof, control circuit 7, display 9, power-supply system 10, on and off switch mouth 11, data signal interfaces 19 and supply socket 6.Oxygen enters oxygen regulating valve 4 in the box by oxygen intake 12, the air pump 2 that air feeds in the box by air intake 13, air that pumps into and oxygen converge to air accumulator 3, and its blended gaseous mixture is delivered to outside the box through mixed gas outlet 14, connecting pipe, face shield, nose cup.Two horizontal respirator occasions are provided with vent valve 5, discharge the gaseous mixture air feed when being used for the patient and exhaling, in order to patient's expiration.The electric control part branch comprises: CPU and control circuit 7, regulate oxygen regulating valve 4 and vent valve 5 by drive circuit 8,15 respectively by control circuit 7, and make an amount of oxygen input and venting in time.Display 9 shows necessary respirator running parameter, display can be located in the seal box and/or be located at outside the seal box, for example in the OPS outside the isolation room, like this, display signal line is connected to interface 19, links by interface 19 on the display in the outer observation control place of isolation room for reading and observing.All the electricity consumption of machine is controlled, is provided by power-supply system 10 and switch mouth 11.
In this example, control and the parameter detecting of control circuit adopt the noncontact mode to carry out, be that transmitting medium carries out for example with infrared ray or rf wave, at this moment the respirator planted agent is provided with infrared ray or radio-wave reception device, this does not illustrate in Fig. 1, this control is sophisticated prior art, and it constitutes no longer here describes.Adopt the noncontact mode to control machine and detection machine parameter, make the node number that must pass seal box 1 minimize as far as possible, the sealing that helps box 1 improves.
Conventional respirator does not have the oxygen input element, and respirator of the present invention adds the oxygen input element, increases the oxygen intake that passes through seal box, is to consider serious symptom respiratory disease patient respiratory difficulty.
Under the situation of respirator by remote manipulation adjusting and signal exchange, various signals are by the transmission of receipts/sender unit, at this moment, pass through the inlet that the inside and outside passage of seal box has only air and oxygen, mixed gas outlet and supply socket, switch also can be the distance type switch,, this has ripe scheme in prior art, like this, just do not have on and off switch to pass through seal box, promptly cancel switch mouth 11.Under the situation of wired transmission, the power supply, the electrical signal line interface that are located on the seal box can be used the waterproof plug socket, and the two separates setting on seal box be for fear of interference, and this waterproof plug socket has now belonged to technology commonly used.At this moment, having display to be located at occasion outside the respirator, signal is drawn by interface 19 by holding wire, and shows signal is guided on the display in remote control place and shown.
Describe several gases now and go into the structure of (going out) mouth 12,13,14, it reaches and intercepts virus, dirt, liquid, but gas is low flow resistance.Fig. 2 is the structural representation of this sealing member.This is the seal configuration that is connecting pipe inside and outside a kind of box.Place to respirator key of the present invention is to accompany a filter membrane 16 by two clamp rings, 17,18 centres, and other parts and due sealing ring setting are conventional design.Described clamp ring 17,18 and film 16 can be independently members, and as shown in Figure 2, this member can unload from sealing member, abandons after the cleaning, and the chance of cross infection is further descended.Described filter membrane 16 be a kind of possess gas is low flow resistance, waterproof, three filtration fabrics that performance is a feature of filtering virus, having countless diameters is nano level micropore, the microporous membrane made from polyflon for example, its average micropore diameter is 140nm, percent opening is up to 82%, on this basis again after ultra-thin entity thin film is handled, its micropore can be between the 2-5nm scope, therefore the above aerosol of hundreds of nanometer is can not be permeable, and the gaseous matter about 0.2nm is then penetrating still good.Can compound again cotton textiles on PTFE (politef) microporous membrane or the layer of one of pure polyester fabric, to reach other requirement such as antibiotic, antistatic.Because this structure of composite membrane has made full use of the microcellular structure characteristic of PTFE excellence, utilize the textile or pure layer of washing to be convenient to do other functional treatment again, reach antistatic,, antibiotic, anti-oil refuses water, characteristic such as fire-retardant, so the filter membrane that constitutes can reach above-mentioned three performances.
The PTFE film is the asymmetry microporous membrane, the positive and negative pore size of film is variant, therefore the cross section of film is a network-like structure, labyrinths such as netted connection, hole edge cover, duct bending are arranged on the three dimensional structure, form a passage by a plurality of micropores, a micropore also may link with a plurality of passages, every square centimeter contains 1,400,000,000 micropores, gaseous matter about each micropore diameter group 0.2nm is big, but much smaller than fluid molecule, for virus, because this micropore, experimental results show that its energy filtering is up to 99% this kind particulate matter less than the diameter of the aerosol particle thing that comprises virus.This kind PTFE film possesses fabulous breathability, water preventing ability, filter every viral thus.
The PTFE film is very thin, thickness is (20～35) μ m, add that the filter membrane 16 that uses should possess such as antistatic in respirator, antibiotic, functions such as enough mechanical strengths and durability need to adopt at PTFE and slim cotton textiles or pure polyester fabric compound, utilization reaches these functional requirements to the finishing functions of these fabrics, further reach excellent adsorption, protective height and efficient definite fungi-proofing, filter dirt effect.Wherein pure polyester fabric can adopt special-shaped fine count fiber.
The way that solves the antistatic problem is that embedding is woven with the machine conductive fiber in fabric, and conductive fiber is spaced apart 0.5-1.5cm, can reach the initial electrostatic surface density less than 1.5 μ c/m
2, wash 50 times after still less than 2.5 μ c/m
