Abstract
The present invention discloses one kind of sterilizing method for inner surface of internal pipeline of medical instrument. The combined supersonic vibration and corona discharge produce water mist of 1-5 micron diameter and with ozone concentration of 15-20 ppm, and exhausted ozone treatment and axial flow heat exchange drying technology are combined, so that sterilizing, deodorizing, drying and tail gas treatment are completed simultaneously. Ozone is dissolved in water mist for homogeneous diffusion without dead angle. The said method can kill various microbes and has excellent bactericidal effect similar to that of peroxy acetic acid and fast bactericidal speed. The present invention is suitable for various types of respirator, anesthesia apparatus, blood dialyzer, etc.
Description
Technical field
The present invention relates to the sterilization method of Medical Instruments, particularly a kind of sterilization method of inner surface of inner pipeline of medical instrument.
Background technology
At present, traditional sterilization method mainly contains three kinds of approach: 1) adopt the ultraviolet photochemistry sterilization; 2) use various chemical reagent (comprising iodine tincture, ethanol, oxirane and hydrogen peroxide etc.) sterilization; 3) high pressure hyperpyrexia sterilization.These methods have been used for the sterilization of the various medical spaces of clinical medicine, Medical Instruments, medical supplies and operation process by routine, its safety and reliability are confirmed by secular practice.But in scientific research with also have many instruments clinically, according to the needs of its function, instrument internal is made up of complicated gas or fluid pipeline mostly, and instrument costliness mostly.For the sterilization of this part instrument, as using disinfection by ultraviolet light, its subject matter is that penetration power is little, and Disinfection Effect is poor, and especially the inwall to the instrument internal pipeline produces bactericidal action hardly, does not have the disinfectant effect.If adopt chemical reagent to carry out disinfection, as the formaldehyde fumigation method, the one, troublesome poeration, fumigation time is long, the 2nd, also can be with secondary pollution, human body is had certain harm, and routine is done a formaldehyde and is heavily steamed sterilization, generally needs 8 hours, and the formaldehyde residue can be difficult to clean attached to each corner of instrument, the more important thing is, because the pipeline complexity can not thoroughly be killed the antibacterial of the inwall of instrument internal pipeline.And this part instrument can not adopt high pressure hyperpyrexia sterilization again.More than three kinds of traditional sterilization methods all can not carry out effective thorough disinfection to this quasi-instrument, can influence the test result of this kind equipment for a long time or cause medical cross infection.As clinical various types of respirators and anesthetic machine commonly used, when specifically using to patient, except that outside (comprising corrugated tubing) can carry out the normal cleaning and sterilizing, inner complicated breather line all can not carry out routine disinfection, and this is the indeterminable difficult problem of traditional for many years sterilization method.
Summary of the invention
At defective or the deficiency that above-mentioned prior art exists, the object of the present invention is to provide a kind of sterilization method of inner surface of inner pipeline of medical instrument.
To achieve these goals, method of the present invention adopts O
3Be prepared into O after the atomized water microgranule is tied mutually

1) preparation of atomized water: use supersonic generator, producing diameter is the atomized water of the fine mist of 1 μ m-5 μ m;
2) O
3Preparation: utilize ozonator, obtain the ozone that concentration is 30ppm～40ppm;
3) above-mentioned atomized water and the ozone made are simultaneously combined with atomized water, obtain containing the water smoke of ozone concentration＞15ppm;
4) connect the container that 500ml metal ion water is housed of 2 polyphones at the exhaust end of the instrument pipeline that is sterilized;
5) water smoke that will contain ozone is then imported the inlet end of the internal pipeline of Medical Instruments, and makes the O that contains from the pipeline discharge
3The container of metal ion water of tail gas by polyphone, with the O in the tail gas
3Fully enter atmosphere after the dissolving;
6) after sterilization finishes, with axial flow heat exchanger heats air to 40 ℃～50 ℃, the air input instrument interior conduit after will heat then, the water smoke that retains in the elimination pipeline.
The present invention utilizes pure oxygen under the high voltage strong electric field condition, and electronics is quickened back and gas molecule collision, O in 10ns by strong electric field power
2Decompose generation antozone (O), only in tens of nanoseconds, oxygen atom combines with oxygen molecule and forms O
3Reuse ultrasonic atomizatio method becomes water the O of the high concentration of water smoke and the generation of corona method
3The O that mixes back formation＞15ppm
3Mist is then directly with O
3Mist input Medical Instruments internal pipeline system keeps O from the tail gas of instrument internal pipe outlet
3Concentration＞5ppm can reach the purpose of thorough disinfection.

(2) O
3The parallel plate type ozone generating-device is used in preparation under normal pressure, medical oxygen gas is produced corona discharge generation high concentration O through the effect of alternation high voltage electric field
3Advantage is that volume is little, simple in structure, functional, easy-maintaining.
(3) vent gas treatment is utilized O
3Very easily water-soluble characteristics feed tail gas in the water that contains metal ion of 500ml * 2, will remain O
3Soluble in water, make it reach environmental protection standard (O
3＜0.5mg/m
3) the back discharging.
(4) dry with the mode heat drying air of axial flow heat exchanger with heat convection, then dry air (40～50 ℃) is imported the interior conduit of instrument, thereby reached rapid elimination water smoke and exsiccant effect.
The O that (1) and (2) is made simultaneously
3Combine with atomized water, its proportion control is at O
3Concentration is＞15ppm, then with O
