We are to pure oxygen generating assembly disclosed in existing patent CN102330107B and CN103173781A, the pure oxygen generating assembly of the application carries out Experiments of Electricity respectively, measure its input voltage U, in addition, we also added matched group, the pure oxygen generating assembly of matched group is, on the basis of pure oxygen generation group disclosed in patent CN103173781A, its porous gas end plate of part is replaced with atresia end plate, and result of the test is as shown in the table.
Result of the test shows, disclosed in the input voltage of the application's pure oxygen generating assembly and existing patent CN102330107B and CN103173781A, the pure oxygen generating assembly of pure oxygen generating assembly and matched group has compared obvious reduction, namely the contact resistance of the application's pure oxygen generating assembly is little, current collection is effective, therefore its Electrochemical corrosion rate is slow, thus assembly is effectively extended service life.
Gas end plate is atresia end plate, and its rigidity reinforced does not find to arch upward under the winding of insulating tape; Secondly, area due to metallic gasket is less than the area of gas end plate, cathode gas diffusion layer, under the constraint of the insulating tape of outside compact winding, the contact pressure between gas end plate and metallic gasket, between metallic gasket and cathode gas diffusion layer can be increased, metallic gasket is made to be easy to fit tightly with gas end plate and cathode gas diffusion layer, based on above 2 reasons, contact resistance can be greatly reduced, thus greatly reduce the voltage of assembly input, and then greatly slow down the electrochemical corrosion of assembly, improve the life-span of assembly; Metallic gasket circumference and gas end plate, form air duct between cathode gas diffusion layer, the oxygen in air enters cathode gas diffusion layer by air duct and participates in reaction.Adopt the micro-oxygen therapeutic apparatus comprising above-mentioned pure oxygen generating assembly, its service life can reach expection, avoids use hidden danger;
Similar with gas end plate, in anode-side, if perforate is too much on oxygen end plate, under the constraint of the insulating tape of outside compact winding, oxygen end plate also can arch up slightly, current collection weak effect between oxygen end plate and anode gas diffusion layer, this reaction is very high at pure oxygen generating assembly input voltage, the electrochemical corrosion of pure oxygen generating assembly can be accelerated like this, thus reduce pure oxygen generating assembly service time, but due to oxygen end plate must have oxygen through hole, the oxygen of generation just can be made to export via the oxygen through hole of gas collection base, through repetition test, find when the number of oxygen through hole is 1-3, can ensure that the phenomenon slightly arched upward does not occur oxygen end plate, thus greatly reduce contact resistance, in addition, when oxygen through hole number is 1, effect is best.
As shown in figure 11, on and off switch is connected with master board, for controlling the On/Off of micro-oxygen therapeutic apparatus; Replacement of oxygen button is connected with master board, for controlling the flow of replacement of oxygen; Time swap button is connected with master board, for controlling the replacement of oxygen time; Oxygen therapy dose button is connected with master board, for controlling oxygen therapy dosage; Program executive button is connected with master board, is used for the treatment of the startup/termination of program; Buzzer is connected with master board, for sending alarm signal; Temperature sensor is connected with master board, for the collection of temperature signal; Humidity sensor is connected with master board, for the collection of moisture signal; Pressure transducer is connected with plug-in unit panel, for gathering the pressure signal of oxygen stream in micro-oxygen plug-in unit.In actual use, environmental factors or Manipulative Factors can cause the too high or instrument of the input voltage of the pure oxygen generating assembly of micro-oxygen therapeutic apparatus to use:
At low temperatures, the electrochemical reaction rates of the pure oxygen generating assembly of micro-oxygen therapeutic apparatus is slack-off, and pure oxygen generating assembly input voltage raises, and oxygen-producing amount reduces; In low humidity situation, the hydrone that the cathode reaction of pure oxygen generating assembly produces can be diffused in air, the hydrone quantity being delivered to anode by PEM is reduced, therefore, oxygen-producing amount also can reduce, meanwhile, because the hydrone being delivered to anode by PEM is reduced, the resistance of PEM can be caused to increase, thus pure oxygen generating assembly input voltage also can be made to raise.The rising of pure oxygen generating assembly input voltage can accelerate the electrochemical corrosion of pure oxygen generating assembly, reduces its life-span; Therefore, when the temperature sensor in master board and humidity sensor measurement to ambient temperature and humidity lower than setting value time, master board sends alarm signal, the buzzer call in master board, Temperature numerical and humidity flicker on display screen; When the temperature sensor in master board and humidity sensor measurement return to more than setting value to ambient temperature and humidity, master board stops sending alarm signal, buzzer in master board stops piping, and on display screen, Temperature numerical and humidity stop flicker.。
In actual use, such as, when adopting partial aeration treatment body surface wound, along with the growth of wound evacuation of pus or wound granulation, the outlet side of the disposable extension tube be connected with oxygen connection may be stopped up, thus cause oxygen pressure in disposable extension tube to raise, when the setting value of force value overpressure sensor, master board sends alarm signal, buzzer call in master board, on display screen, " working properly " character disappears, there is pressure blockage alarm, pure oxygen generating assembly stops producing oxygen, on display screen, flow number is shown as zero, when in disposable extension tube, oxygen pressure returns to below the setting value of pressure transducer, master board stops sending alarm signal, buzzer in master board stops piping, display screen pressure is blocked alarm and is disappeared, there is " working properly " character, pure oxygen generating assembly recovers to produce oxygen automatically, on display screen, flow number is shown as setting value.
In addition, micro-oxygen plug-in unit is when inserting main frame, if card i/f and HPI do not contact or loose contact, master board sends alarm signal, buzzer call in master board, on display screen, " working properly " character disappears, and occurs connection error alarm, when card i/f is connected normally with HPI, master board stops sending alarm signal, buzzer in master board stops piping, and on display screen, connection error alarm disappears, and occurs " working properly " character.
The application, by the setting of temperature sensor, humidity sensor, pressure transducer, buzzer and display, achieves the real-time monitoring to pure oxygen generating assembly, ensure that the normal use of micro-oxygen therapeutic apparatus.
