The sealing gasket can deform in the annular groove so that the circular base plate can be in contact with the sealing gasket in the sealed cavity consistently, complete sealing between the outside and the inside of the protective shell body is ensured, outside moisture or dust is completely prevented from entering the therapeutic instrument through the on-off key, the control function and the flexibility of switching-on and switching-off of the therapeutic instrument before and after the therapeutic instrument is used are ensured, the using efficiency of the therapeutic instrument is improved, and meanwhile the medical accident occurrence rate caused by the failure of switching-on and switching-off is reduced.
Description
Technical field
The present invention relates to a kind of therapeutic instrument, specifically refer to a kind of therapy apparatus protection housing.
Background technology
During ionic curing machine treatment, according to different focuses, select the different treatment syringe needle contact of diameter or insert in body foci, the high electric field intensity forming in the minimum air gap between utilizing contact and organizing makes gas molecule separated, produces plasma flame.When selecting strong output, moment produces the high temperature of 3000 ℃ of left and right, pathological tissues is gasified and disappear.Meanwhile, due to gasification layer below also have very thin solidification layer, can stop hemorrhagely, protection surface texture, heals rapidly wound.When selecting weak output, can make lesion tissue solidify or carbonization and necrosis reaches the object for the treatment of with this.
Current ionic therapy apparatus effect is on the market extensive, but in medical care process, outside the switch of ionic therapy apparatus is exposed to, extraneous dust or steam easily enter in the electronic circuit of therapeutic instrument inside, the most directly consequence is that switch key is directly malfunctioning when wound debridement, and therapy apparatus after operation completes cannot be stopped immediately, and interference treatment personnel's judgement, causes malpractice.
Summary of the invention
The object of the present invention is to provide a kind of ionic curing machine, avoid extraneous dust or steam to enter into therapeutic instrument inside and cause the malfunctioning of switch through on & off switch, and then reduce the fault rate of therapeutic instrument.
Object of the present invention is achieved through the following technical solutions:
A kind of therapy apparatus protection housing, comprise on & off switch and the protection housing that has through hole, in described protection housing, be provided with the seal chamber of tubular, on the inwall of seal chamber, have annular groove, sealing gasket is fixed in annular groove, and on & off switch is placed in seal chamber through through hole, is connected with the motion bar that seal chamber bottom is run through in one end in the bottom of on & off switch, on motion bar, be fixed with circular bottom plate, the excircle of circular bottom plate contacts with sealing gasket all the time; Also comprise cam bit and fixed block, fixed block is arranged in protection inner walls, cam bit is rotated and is arranged on protection housing by turning cylinder, and on turning cylinder outer wall, have coarse thread, on the side of motion bar, cingulum is installed, cingulum coordinates with coarse thread, on fixed block, rotate and be provided with contact supporting, the side of contact supporting is provided with roller, and roller contacts with cam bit, in the bottom of contact supporting, is connected with contact; Bottom at protection housing is provided with contact base, on contact base, is fixed with contact chip, and described contact chip is placed on the swing route of contact.When the present invention works, protection housing is embedded on therapeutic instrument casing, contact chip is connected with therapeutic instrument internal circuit by wire, on & off switch is pressed, circular bottom plate moves down with motion bar, the bottom of motion bar is run through seal chamber bottom and is entered into protection enclosure interior, the side of motion bar is provided with cingulum, cingulum coordinates with the coarse thread on turning cylinder, drive cam bit rotates counterclockwise, contact condition between cam bit and roller becomes released state simultaneously, contact holder is a bit swinging on fixed block under the effect of self gravitation, until contact and contact chip collision are bonded together, contact chip connects therapeutic instrument internal circuit by wire, make therapeutic instrument start normal work, when therapeutic instrument quits work, on & off switch is upwards promoted, motion bar drives cam bit to clockwise rotate, and cam bit keeps and the contacting of roller again, makes contact separated with contact chip, and then therapeutic instrument is quit work.
Wherein, the setting of cam bit and contact holder, the connected mode that traditional switch flexure strip is clashed into becomes flexible connection, by the adjusting of cam bit, can avoid the shock loss of switch flexure strip, the service life of greatly improving gauge tap; And can there is deformation in sealing gasket and then circular bottom plate is contacted with sealing gasket all the time in seal chamber in annular groove; guarantee the sealing completely between extraneous and protection enclosure interior; stop extraneous steam or dust and enter into therapeutic instrument inside by & off switch; guarantee control function and the flexibility ratio of switch after therapeutic instrument before use; the service efficiency that improves therapeutic instrument reduces the malpractice incidence rate causing because of malfunctioning switch simultaneously.
Described on & off switch bottom is provided with screwed hole, and the upper end of motion bar is threaded with on & off switch through screwed hole.In the use procedure of upper time, have unavoidably dust and enter into bright cavity by through hole, on & off switch is threaded with motion bar, on & off switch can be disassembled, convenient manually to seal chamber internal cleaning, guarantees the tidiness in seal chamber.
Also comprise torsionspring, the two ends of described torsionspring are connected with contact supporting, fixed block respectively.When on & off switch presses down, cam bit is separated with roller, contact is done and is freely swung under the effect of contact holder self gravitation, until contact with contact chip collision, now, the torsionspring between fixed block and the frame of contact is stretched, according to active force and counteracting force, torsionspring provides a pulling force contrary with its direction of motion to contact holder, avoids the excessive collision of contact and contact chip and causes impaired.
The present invention compared with prior art, has following advantage and beneficial effect:
1, the present invention, can in annular groove, there is deformation and then circular bottom plate is contacted with sealing gasket all the time in seal chamber in sealing gasket, guarantee the sealing completely between extraneous and protection enclosure interior, stop extraneous steam or dust and enter into therapeutic instrument inside by & off switch, guarantee control function and the flexibility ratio of switch after therapeutic instrument before use, the service efficiency that improves therapeutic instrument reduces the malpractice incidence rate causing because of malfunctioning switch simultaneously;
2, the present invention, in the use procedure of upper time, had unavoidably dust and enters into bright cavity by through hole, and on & off switch is threaded with motion bar, on & off switch can be disassembled, convenient manually to seal chamber internal cleaning, guaranteed the tidiness in seal chamber;
3, the present invention, contact is done and is freely swung under the effect of contact holder self gravitation, until contact with contact chip collision, now, torsionspring between fixed block and the frame of contact is stretched, according to active force and counteracting force, torsionspring provides a pulling force contrary with its direction of motion to contact holder, avoids the excessive collision of contact and contact chip and causes impaired.
