Description
Technical field
This utility model relates to a kind of sterilizing installation, relates in particular to a kind of hydrogen peroxide that adopts to the carry out disinfection low-temperature sterilization equipment of sterilizing of medical apparatus and instruments, belongs to the medical apparatus sterilizing field that learns a skill.
Background technology
At medical domain, the sterilization of medical apparatus and instruments is particularly important, now tool advantage and the most universal medical apparatus sterilizing sterilization method are disinfectant with hydrogen peroxide sterilizing, for improving sterilization effect, shorten sterilization time, reducing sterilizing cost, conventionally all need to adopt the mode of heating or ionization hydrogen peroxide liquid is vaporized or plasma after, then to the medical apparatus and instruments sterilizing that carries out disinfection.Ionization principle be due to cavity and electrode network all charged, and cavity positively charged, electrode network is electronegative, electric discharge produce power between cavity and electrode network, the energy that hydrogen peroxide gas between cavity and electrode network is discharged generation hits lives into plasma, on electrode network, be evenly distributed with many apertures, make accessible the passing of hydrogen peroxide gas energy in whole space in cavity, make the hydrogen peroxide gas in whole space all by the energy of discharge generation between cavity and electrode network, be hit and live into plasma, the medical apparatus and instruments being placed in glove hurdle is carried out to sterilizing.
But because the perforate majority on current electrode network is circular hole or square hole, and pitch-row is too close, have the following disadvantages: if square hole, a kind of steriliser as disclosed in Chinese patent 200920031191.2, because the square hole of opening on electrode network has wedge angle, easily produce point discharge, cause sparking, so medical apparatus and instruments is being carried out in the process of sterilizing, is having pair medical apparatus and instruments to produce the phenomenon of burning candle; If electrode network is out circular hole, the easy generation current whirlpool in circular place, and because electric discharge position is physical location but not through hole position, physical location size between circular hole is uneven, a little less than guiding discharge has and has by force, and the electric charge at the large position of entity area can pull the electric charge at the position that area is little, and further guiding discharge is uneven, cause sparking, thereby the medical apparatus and instruments of sterilizing is caused and burns candle.
Summary of the invention
In order to solve prior art above shortcomings, a kind of electrode network of the special proposition of this utility model is driven the hydrogen peroxide low-temperature plasma steriliser of mounting hole, comprise cavity, control system, pressure probe, vacuum pump, electrode network, between electrode network and cavity, insulate and be connected, cavity positively charged, electrode network is electronegative, offers a plurality of waist through hole on electrode network, and mounting hole two ends are circular arcs.This improvement protects medical apparatus and instruments and is not burnt candle when can carry out abundant sterilizing to apparatus.
this utility model is for solving its technical problem, and the technical scheme adopting is:
a kind of electrode network is driven the hydrogen peroxide low-temperature plasma steriliser of mounting hole, comprise cavity, control system, pressure probe, vacuum pump, electrode network, cavity positively charged, electrode network is electronegative, on electrode network, offer a plurality of waist through hole, mounting hole two ends are circular arcs.
Between the two ends arc of mounting hole by straight transitions.
The two ends arc radius of mounting hole is 7.5 millimeters, and the centre-to-centre spacing of two ends arc is 15 millimeters.
On electrode network, mounting hole is uniformly distributed, and between hole, transverse center distance is 14 millimeters, and longitudinal center's distance is 44 millimeters.
Between electrode network and cavity, insulate and be connected, and the distance between electrode network and cavity is 10 to 30 millimeters.
Electrode network adopts aluminum alloy materials to make.
Electrode network material thickness is 2 millimeters.
compared with prior art, the beneficial effects of the utility model are:
a kind of electrode network in this utility model is driven the hydrogen peroxide low-temperature plasma steriliser of mounting hole, and its electrode network adopts the aluminum alloy plate materials of 2 millimeters thick to make, and its beneficial effect is that aluminium alloy electric conductivity is high, and quality is light; On electrode network, evenly offer a plurality of waist through hole, mounting hole two ends are circular arcs, excessive by straight line between the arc of two ends, its beneficial effect is: avoid producing point discharge because of wedge angle, avoid because of circular generation current whirlpool simultaneously, thereby stop charge concentration and cause spark phenomenon, avoid apparatus to produce and burn candle.
Between electrode network and cavity, insulate and be connected, and the distance between electrode network and cavity is 10 to 30 millimeters, the two ends arc radius of mounting hole is 7.5 millimeters, middle straight transitions, the centre-to-centre spacing of two ends arc is 15 millimeters, and between Kong Yukong, transverse center distance is 14 millimeters, longitudinal center's distance is 44 millimeters, its beneficial effect is: through test of many times, under this state, between electrode network and cavity, discharge effect is best, and the circulation of the hydrogen peroxide gas in the whole space of cavity effect is also best, so the ionization effect that the energy of discharge generation carries out hydrogen peroxide gas is best, thereby apparatus is reached to abundant sterilizing.
And now between Kong Yukong, laterally and longitudinally entity area is substantially equal; and the electrode network entity area after improving is larger under state compared to existing technology; this improved beneficial effect is: discharge more even; can not produce charge attraction; also be not easy electrode network panel to be deformed or breakdown because of current unevenness; thereby avoid producing spark phenomenon, better protection is not burnt candle by the apparatus of sterilizing.
