Description
One. technical field
The invention belongs to high-concentration ozone water production and applied technical field, particularly can reach medical sterilization and disinfection application requiring, produce the method for high-concentrated ozone sterilizing agent.And the specific equipment of realizing aforesaid method.
Two. background technology
Along with the development of society, industrial injury and traffic accident increase severely, and debridement becomes increasingly complex.Use traditional instruments and method, the debridement process wastes time and energy, and is destructive big to wound; Thimerosal, physiological saline and other medical disposable materials that the consumption of debridement process need is a large amount of; The used thimerosal of debridement is generally the tincture of iodine, Iodophor, and hydrogen peroxide etc. are big to the wound pungency, a lot of patient's pain unbearably, the deterioration that pain can aggravate one's illness.Traditional irrigation and disinfection way has simple and easy washing bottle flushing, the flushing of ball extruding type, sterilization dressing bowl to pour flushing into, takes the photograph son folder cotton balls scouring etc.These methods are because the washing fluid flow velocity is low, wash not thoroughly, to complicated wound or than gash the place that does not flush is arranged, the debridement thoroughness often can not get guaranteeing, be easy to leave dead space or debridement blind area, this also is the major cause of the easy secondary debridement of wound postoperative infection.More than these all cause and use inconvenience and final effect not good.
The sterilization effect of ozone and ozone water gains public acceptance already, and it has the incomparable advantage of other sterilizing agent: be decomposed into oxygen after the sterilization rapidly, non-secondary pollution helps environmental protection; When being applied to the sterilization cleaning of wound, its degradation production oxygen also helps to remedy the anoxic of wound tissue, can accelerate the speed of tissue oneself growth and healing; Ozone and ozone water are less to the pungency of tissue, can reduce patient's misery.
But because ozone self, the also very difficult ozone concn that stably obtains of the technology of development reaches the above ozone water of 4mg/L at present.This be because: the solubleness of (1) ozone gas itself is not high; (2) ozone easily decomposes under usual condition, and the transformation period in water has only 15～30 minutes, therefore must be existing with existing system, can not store; (3) dissolving of ozone is followed Henry's law (that is: at a certain temperature, when gas dissolving reaches balance, gas in liquid solubleness and gas phase in this gas be divided into direct ratio), still the concentration of ozone in gaseous product is too little but though the ozone amount that methods such as high-voltage corona method in the past, ultraviolet method produce is low, be unfavorable for very much the dissolving of ozone, utilize the high-concentration ozone water device structure complexity, with high costs of this method; Though and the concentration of ozone gas that developed electrolytic process ozone generating apparatus generation faster in recent years can reach 18～20%, but gas yield is smaller again, and bad with the hybrid technique solution of water so far, the technology that generates stable high-concentration ozone water is still immature.
It is ozone gas source that Chinese patent ZL02138905 proposes employing low-voltage electrolysis pure water ozone generating-device a kind of, in conjunction with the adjusting control that absorbs the micro-minute-pressure ozone gas that generates continuously, control quantitative water temperature by the compression refrigeration device, make it under pressure, to circulate, flow through high negative pressure ejector continuous absorption, mix ozone, produce the method for middle and high concentration ozonated water within a certain period of time.But the subject matter of its existence has:
1. adopt an electrolysis type ozone generator separately, though the ozone concn of its generation is higher, its ozone output was only had an appointment 600～800mg/ hour at present, wanted to make a large amount of ozone solutions can only prolong the cycling time of gauge water in the water.
2. only can be by the concentration of the ozone water estimating cycling time to generate, in case condition changing such as the system fault or extraneous water, temperature and cause consistency of ozone water to reduce make troubles for the occasion that requires high-concentration ozone water to use.
3. its micro-minute-pressure control enclosure directly is communicated with ambient atmosphere, will perhaps directly replenish not enough from outside air by the inspiratory capacity of air regulating device confined jet device when electrolysis ozone generating unit gas production rate is not enough.The inspiratory capacity of confined jet device must increase cycling time, and replenish air can cause ozone in mixed gas density loss and influence the solute effect of ozone, and the nitrogen that sucks from outside air can produce deleterious oxynitride with ozone generation chemical reaction.
4. pre-cyclic water tank is an independent structure of having only upper and lower each two interface, mixes back undissolvable ozone of residue and oxygen with water fully by the ozonolysis equipment emptying, causes the waste of ozone and oxygen.
5. adopt the method that drops into ice cube to give circulating water cooling inconvenient under the situation of practical application; And adopt compressor refrigeration one is that noise is big, the 2nd, and temperature control is inconvenient, control accuracy is low, and the 3rd, can only lower the temperature and can not heat up.
Also have in addition by feedwater and ozone gas and exert pressure with the method for raising ozone solution degree, but its equipment manufacturing cost increases greatly, the processing of remaining abundant residues ozone gas has also increased cost.Other method that can not generate the above high-concentration ozone water of 4mg/L is not introduced one by one at this.
Therefore, overcome the ozone technology bottleneck of present development, stable, convenient, obtain ozone with high concentration water at low cost and become an important problem.This problem will effectively promote in the application to the higher industry of the concentration requirement of ozone water such as medical treatment, electronics after solving.

Five. embodiment
Below the embodiment of processing method of the present invention and wound disinfection sterilization cleaning equipment is carried out the drawings in detail explanation, the professional and technical personnel can be clearer to characteristics of the present invention and advantage.
The detailed operation flow process of processing method of the present invention is as shown in Figure 1:
A. many electrolysis type ozone generators (19) in parallel are opened, and produce ozone gas, enter high-voltage corona formula ozonizer (24) after making this gas drying dehumidifying again, further improve the output and the concentration of ozone;
B. at first open total water intaking valve (5), disinfectant stock solution is attracted by recycle pump (6), sucks ozone gas during through high-pressure spray negative pressure absorption unit (7), passes through static mixer (8) again, enters disinfectant box (9), becomes ozonization agent work in-process;
C. after ozonization agent work in-process are full of disinfectant box (9), liquid level sensor (11) sends electrical signal, Controlling System is opened sterilizing agent recycle valve (15) when closing total water intaking valve (5), then the inlet of recycle pump (6) switches to the main cabin (32) of disinfectant box (9), in this cabin, attract the work in-process sterilizing agent, pass through high-pressure spray negative pressure absorption unit (7) once more and suck ozone gas, pass through static mixer (8) once more, enter the secondary cabin (33) of disinfectant box, overflow weir (34) and (35) from top, major and minor cabin spill into main cabin (32) again;
D. the work in-process sterilizing agent constantly circulates according to the described path of step c, and the ozone concn that detects absorption until ozone concentration sensor (14) reaches set(ting)value (4～20mg/L);
E. after the liquid level sensor (11) in the disinfectant box (9) detects sterilizing agent suction sky, repeat a～d step again.
In the full cycle process, temperature sensor (12) on the disinfectant box (9) detects the sterilizing agent temperature, freezes or heats by being close to semiconductor cooler (13) on disinfectant box (9) outer wall, realizes sterilizing agent is carried out the temperature two-ways regulation.Semiconductor cooler (13) refrigeration cool-down is to improve the ozone solution degree and to reduce cycling time if the sterilizing agent temperature is too high; Semiconductor cooler (13) heats if the sterilizing agent temperature is too low, avoids supercooled water to be sprayed onto and causes discomfort on the human body.
Fig. 2 and shown in Figure 3 be detailed structure and the sectional view thereof of a kind of embodiment of disinfectant box (9).As can be seen, disinfectant stock solution and work in-process always enter from the bottom interface of secondary cabin (33) among the figure, overflow into main cabin (32) again after filling with secondary cabin (33), are attracted away by recycle pump (6) or squirt pump (17) from main cabin (32) again.The separation structure advantage in this major and minor cabin is: " short circuit " phenomenon takes place in one side when having avoided the lower passage of the two to pass in and out liquid at the same time; In flooding process, carried out gas-water separation on the one hand, made us uncomfortable ozone smell thereby contain in the sterilizing agent of avoiding ejecting in the ozone gas minimizing irrigation and disinfection environment; At last, be repeated to absorb after making gas (comprise and do not have the by product of dissolved ozone and electrolysis type ozone generator oxygen) after the gas-water separation to produce ozone once more by high-voltage corona formula ozonizer (24).
The top exit in the main cabin (32) of disinfectant box (9) is connected with ozone and decomposes catalyst converter (10), will enter the external world after decomposing by undissolvable ozone gas after the gas-water separation, in order to avoid the deozonize smell that causes of environment to external world.The ozone concentration sensor (14) that install the back, main cabin (32) of disinfectant box (9) can send level to the Controlling System of equipment, can stop circulation when reaching the ozone concn of systemic presupposition, begin to spray sterilization.The top exit in the secondary cabin (33) of disinfectant box (9) is connecting the air-permeable envelope that blocks water (22), it with pass through removal moisture drying device (23) again after the anode ozone outlet of electrolysis water tank (20) is in parallel, enter high-voltage corona formula ozonizer (24) then and improve ozone concn, receive again on the suction port of high-pressure spray negative pressure absorption unit (7), can from the secondary cabin of disinfectant box (33), cover the shortage during greater than the gas production rate of electrolysis type ozone generator (19) when the inspiratory capacity of high-pressure spray negative pressure absorption unit (7) like this.
In the electrolysis type ozone generator that has developed and the hybrid technique of water, because the non-return effect of ejector and anodic gas outlet intermediary check valve is undesirable, and the situation of negative pressure often appears in anode brine electrolysis case in jet attraction process, the water that often causes the external world not meet the electrolysis requirement enters the situation (electrolysis type ozone generator require its electrolysis raw material electrical conductivity of water must below 5 μ s/cm) of electrolysis water tank, the end, fall in this ozone amount and ozone concn that just causes electrolysis type ozone generator to produce, dissolved ozone density loss in the water can shorten electrolysis type ozone generator work-ing life even damage producer when serious.In technology of the present invention, increased the air-permeable envelope that blocks water (21) at the anode export of electrolysis water tank (20).This film can make ozone gas flow out smoothly, but the water that can stop the external world not meet the electrolysis requirement enters electrolysis water tank (20), can also prevent electrolysis water tank (20) thus the electrolysis raw water be sucked away the unnecessary consumption of the brine electrolysis that causes and damage high-voltage corona formula ozonizer (24) with ozone gas.This air-permeable envelope that blocks water (20) and (21) all must be selected the corrosion that can tolerate ozone for use and to the nontoxic medical grade material of human body, include but are not limited to PTFE hydrophobic micropore filtering membrane.
Can easyly stably obtain the ozonization agent that concentration can reach 4～20mg/L through above method and apparatus, again through regulating the injection of the multifunction spray gun that multiple spray regime such as spraying, fluid column stream, spray and flow and pressure also can regulate, can act directly on tissue or other surface that is sterilized object is washed and sterilization and disinfection.
By above-mentioned explanation, can understand the processing method of generation sterilizing agent of medical high concentrition ozone of the present invention and the mode of operation and the advantage of wound disinfection sterilization cleaning equipment fully.Certainly, structure disclosed herein just in order to describe the present invention for embodiment.Form, structure or layout, connecting mode to some component can be done some changes, but still do not deviate from spirit of the present invention, also should be within protection scope of the present invention.Scope of the present invention is limited by the accompanying claims.
Equipment by this processing method manufacturing has health simple to operate, easy to use, safe, sterilization effect high efficient and reliable, storage and custody facility in actual use, and the raw material of consumption obtains convenient and cheap advantage.During high-pressure high-flow wound is carried out pressure washing and massage, remove the clot and other dirt that attach at wound sore face, can as the manual wiping wound of things such as absorbent cotton, not cause patient's wound pain; The sterilization that can carry out disinfection apace during the low pressure low flow is saved the operating time and reduced the consumption of wound scavenging solution, and is fast convenient; In flow be used for the flushing and the sterilization of common wound under the relatively clean situation of wound surface, speed is faster, save time.Because of the misery of sterilizing, flushing has caused, shorten the time of treatment of wounds when so just having significantly reduced patient's treatment of wounds, alleviated medical personnel's labour intensity, reduced the cost of medical department's treatment of wounds.
The present invention is directed to different wound site and in various degree wound can both totally thoroughly get express developed, reduce hemorrhage, pain and infection, can control the flow and the pressure of sterilizing agent, time saving and energy saving, handled easily, alleviate the patient suffering and reduce medical personnel's workload, easy to use and be beneficial to environmental protection, be the medical disinfecting purging method and the equipment of a new generation.
