Description
Technical field
The invention belongs to technical field of plasma, particularly relate to the protection machine of a kind of plasma laryngoscope sterilizing unit
Structure.
Background technology
The application of plasma technique is more and more extensive, such as ozone synthesis, environmental conservation, manufacture of materials manufacture, biology
The fields such as sterilizing, the generating means of the most multiple plasma arises at the historic moment, such as spool formula DBD plasma producing apparatus, edge
Surface plasma generating meanss etc., at present, applying at hospital's otorhinolaryngologic laryngoscope sterilizing unit is i.e. according to spool formula medium
The principle of barrier discharge forms, i.e. plasma laryngoscope sterilizing unit, the high-voltage section of existing plasma laryngoscope sterilizing unit
Point it is the copper sheet structure that is wrapped in outside quartz medium pipe, during actually used, there will be the phenomenon of upper end sparking, because of
This can only solve the problem of upper end sparking high-pressure section as far as possible away from the mouth of pipe of quartz medium with this, but through substantial amounts of
Experiment finds, upper end does not such as have high-field electrode, then this region will not produce plasma, and this not only badly influences the effect of sterilization
Really, and this electric discharge can damage power supply and even damage Pharyngoscope.
Summary of the invention
It is an object of the invention to provide the protection mechanism of a kind of plasma laryngoscope sterilizing unit, mechanism it can be avoided that
The generation of mouth end spark phenomenon, and reach the mouth of pipe uniform plasma of generation, it is ensured that bactericidal effect.
The present invention is the improvement of existing plasma laryngoscope sterilizing unit upper end, and concrete technical scheme is as follows:
The invention mainly comprises ground electrode, high-field electrode and medium tube, wherein ground electrode is metal tube with holes, ground
Being socketed the medium tube being made up of isolation material outside electrode, described medium tube is made up of three parts being connected as a single entity, i.e. first
Being divided into narrow tube, the top of narrow tube is cased with large diameter pipe, narrow tube and large diameter pipe outside apical position
Top is linked together by an annular otic placode, and it is empty that described narrow tube top and otic placode, large diameter pipe form an annular
Between, described high-field electrode is socketed in outside the large diameter pipe of above-mentioned medium tube, and above-mentioned annular space is stretched on the top of high-field electrode
In.
As one of them preferred version of the present invention, the material of described medium tube is quartzy or ceramic.
As another preferred version of the present invention, described high-voltage motor is metal tube or sheet metal.
High-field electrode is wrapped up by the present invention by the mouth of pipe of medium tube laterally, avoids mouthful end spark phenomenon with this
Occur, enable the mouth of pipe to produce uniform plasma, thus ensure sterilization processing effect at the mouth of pipe of sterilizing unit upper end；Work
Time, it would be desirable to the endoscope of sterilizing is inserted from above in ground electrode, and high-field electrode is connected to high voltage power supply, by ground electrode even
Receiving ground, plasma produces between medium tube and ground electrode, thus plays the sterilizing effect to endoscope exterior surface.
The present invention compared with prior art has the advantage that
1, it can be avoided that the generation of mouth end spark phenomenon, reaches the mouth of pipe and produces uniform plasma, it is ensured that bactericidal effect；
2, simple structure, easy to make, with low cost；
3, applied range, service life is long.
Accompanying drawing explanation
Fig. 1 is the generalized section (main apparent direction) of the present invention.
Fig. 2 is the bactericidal effect figure of prior art.
Fig. 3 is the bactericidal effect figure of the present invention.
Detailed description of the invention
Next the most in conjunction with the accompanying drawings and embodiments the present invention is elaborated
As it is shown in figure 1, ground electrode 1 is white steel pipe with holes, outside ground electrode, it is socketed the medium tube being made up of quartz, described
Medium tube is made up of three parts being connected as a single entity, i.e. Part I is narrow tube 2-1, and the top of narrow tube is near position, top
The top being cased with large diameter pipe 2-2, narrow tube and large diameter pipe outside putting is linked together by an annular otic placode 2-3,
Described narrow tube top forms an annular space with otic placode, large diameter pipe, and high-field electrode 3 is copper pipe, and it is socketed in above-mentioned
Outside the large diameter pipe of medium tube, the top of high-field electrode is stretched in above-mentioned annular space.
Application example
Prior art and the present invention are carried out respectively sterilization experiment, observes bactericidal effect after dielectric structure changes, wherein two
Individual experiment all keeps discharge voltage 8kV, and discharge frequency is 7kHz, changes discharge time 10s, 20s, 30s, 40s, 50s, 60s, sees
Examine bactericidal effect.
Fig. 2 is the bactericidal effect figure of prior art, and Fig. 3 is the bactericidal effect figure of the present invention, by contrast, Fig. 3's
Bactericidal effect significantly improves compared with Fig. 2 bactericidal effect, i.e. the present invention compared with prior art substantially increases the sterilization of device
Effect.
