Description
Technical field
The present invention relates to a kind of cleaning devices for medical apparatus sterilizing, transmit energy using jet stream turbulent diffusion
Amount and quality, belong to medical instrument cleaning applications.
Background technique
Cleaning, disinfection and the sterilizing of medical instrument are the key that prevention and control inside-hospital infection, guarantee quality of medical care hand
One of section, it may be said that unexcellent medical apparatus sterilizing and sterilization technology, there will be no the development of modern surgery technology, just
It cannot be guaranteed that various wellability Clinics are carried out.The development of modern medical techniques, the especially hair of modern surgery technology
It opens up, the requirement to disinfecting technical is higher and higher, dependence is more and more strong, how scientifically and rationally to use disinfecting technical
To prevent and control nosocomial infection to be one key project of modern medicine.
Existing medical instrument cleaning and sterilization mostly uses greatly the disinfectants soaking disinfection such as glutaraldehyde, not enough thoroughly, disinfectant
Disinfection need to be made into various concentration according to the difference of article, not only inconvenient for use, and bactericidal effect is bad, and staff connects for a long time
Touching disinfectant can also cause serious injury to skin, nail.
Current medical instrument cleaning equipment mainly has medical automatic washing machine and ultrasonic cleaning machine for medical purpose.It is medical complete
Automatic rinser is to spray foam by high-pressure jet, in addition 90 degree of hot water sterilize and rinse extensively drying.Ultrasonic cleaning machine for medical purpose is
It is cleaned by ultrasonic activation, the place for artificial less cleaning.But the high-pressure jet spray foam in cleaning machine is using normal
The ejector of rule will also cooperate 90 degree of hot water that could complete to sterilize and rinse, and there are the places of less cleaning.
Summary of the invention
The present invention provides that one kind is high-efficient, effect is good for deficiency existing for existing medical apparatus sterilizing clean technologies
Can reach heating and cleaning action for the clean integrated device of medical instrument heating disinfection.
Of the invention is used for the clean integrated device of medical instrument heating disinfection, using following technical scheme:
The device, including nozzle, self-oscillation chamber, trunnion and diffuser；Nozzle be connected to self-oscillation chamber into
On mouth end, the spout of nozzle is in self-oscillation chamber；The input end of trunnion be connected to the outlet end of self-oscillation chamber and
In self-oscillation chamber interior, the input end of trunnion is tapered, constitutes the impingement angle of self-oscillation chamber, the import of diffuser
It exports and connects with trunnion.
The indoor impingement angle of self-oscillation chamber is 120 °.
The ratio D2/D1 of the nozzle diameter D1 of the inlet diameter D2 and nozzle of the diffuser is 2~2.5.
Ratio L1/D3 of the larynx mouth away from L1 (the distance L1 of the import of the spout of nozzle to trunnion) and chamber diameter D3 is 0.6
~0.8.
The discharge area of the diffuser and the ratio of inlet -duct area are 3~8.
The ratio of the inlet diameter D2 of the chamber diameter D3 and diffuser of the self-oscillation chamber is 5~6.5.
Above-mentioned apparatus is used to that drift to be added in the working water for entering the device to the rinse stage of medical instrument spray cleaning
Wash glazing agent.
When work, by the working water of water pump suck purge, sprayed from nozzle after working water is pressurized；Into self-excitation
Chamber is shaken, pulse cavitating jet is formed, generates high temperature and pressure, and generate a large amount of high activity OH, working water that treated is most
It is discharged afterwards by diffuser, medical instrument is cleaned.
To medical apparatus sterilizing, Hydrodynamic cavitation is produced the energy that the present invention is generated using cavitation jet bubble breaking in the process
Raw a large amount of high activity OH can be remaining on oxidizing medical instrument chemical substance, reach as high as 90 DEG C of high temperature and high pressure meeting
Make the chemical bond rupture in molecule to achieve the purpose that macromolecular chemistry organic matter of degrading.Realize heating disinfection with it is clean
Effect, it is high-efficient, effect is good.
Detailed description of the invention
Fig. 1 is structural schematic diagram of the present invention for medical instrument heating disinfection cleaning integrated device.
In figure: 1. nozzles, 2. self-oscillation chambers, 3. trunnions, 4. diffusers, 5. diffuser imports, the outlet of 6. diffusers.
Specific embodiment
It is of the invention to be used for the clean integrated device of medical instrument heating disinfection, structure as shown in Figure 1, include nozzle 1,
Self-oscillation chamber 2, trunnion 3 and diffuser 4.Nozzle 1 is connected to the input end (at inlet) of self-oscillation chamber 2, spray
Mouth is located at the inside of self-oscillation chamber 2.3 input end of trunnion is connected to the outlet end (right side in Fig. 1 of self-oscillation chamber 2
End), the import of trunnion 3 is in the self-excited oscillation cavity chamber interior, and trunnion 3 is in the front end (input end) of self-oscillation chamber interior in cone
Shape constitutes the impingement angle A of self-oscillation chamber.Diffuser 4 is connect with trunnion 3, and the interior sky of diffuser 4 is diffuser 4 and trunnion 3
Connection.The diameter (D2) for the import 5 that the diameter (D4) of the outlet 6 of diffuser is greater than.
It is many to the factor of medical apparatus sterilizing cleaning device working performance to influence cavitation jet, furthermore the cone of diffuser 6
The factors such as degree all have an impact to its working performance.Comprehensive various factors, by many experiments, the correlation of various parameters in the present invention
Relationship is as described below.
Spout (right output port of nozzle 1 in Fig. 1) diameter of nozzle 1 is D1.The diameter of diffuser import 5 (left end in Fig. 1)
For D2 (the namely internal diameter of trunnion 3).The diameter of diffuser outlet 6 is D4 (Fig. 1 right end).The spout of nozzle 1 to trunnion 3 into
The distance (larynx mouth away from) of mouthful (right end in Fig. 1) is L1.Impingement angle (the front end cone angle of trunnion 5) in self-oscillation chamber 2 is A,
The chamber diameter of self-oscillation chamber 2 is D3.The relationship of so each parameter are as follows:
1. the ratio D2/D1 of the nozzle diameter D1 of the inlet diameter D2 and nozzle of the diffuser is 2~2.5；
3. the impingement angle A in self-oscillation chamber 2 is 120 °.
4. ratio L1/D3 of the larynx mouth away from L1 and chamber diameter D3 is 0.6~0.8.
5. the ratio of 6 area of outlet of diffuser 4 and 5 area of import is 3~8.
6. the ratio of the inlet diameter D2 of the chamber diameter D3 of self-oscillation chamber 2 and diffuser 6 is 5~6.5.
Above-mentioned apparatus is used to that drift to be added in the working water for entering the device to the rinse stage of medical instrument spray cleaning
Wash glazing agent.The working water of water pump suck purge sprays after working water is pressurized from nozzle 1, into self-oscillation chamber
2, pulse cavitating jet, a large amount of high activity OH of generation are formed, working water that treated is discharged finally by diffuser 4.Benefit
For the energy generated with cavitation jet bubble breaking to medical apparatus sterilizing, high activity OH can be remaining on oxidizing medical instrument
Chemical substance, while high temperature and pressure is generated, make the chemical bond rupture in molecule, thus larger molecular organics of degrading.
