Abstract
An automatic test device of corrosion resistance and sterilization resistance of dental equipment consists of a sterilization chamber, a loading rack, which is used to place or suspend to-be-tested equipment, is inside the sterilization chamber, and the sterilization chamber is connected with a steam generator through a steam inlet. The steam generator fetches water from a purified water tank or a purified water processing system, and sends steam to the sterilization chamber, a temperature sensor enters the sterilization chamber through a connector of the sterilization chamber and monitoring temperatures of front, rear, top and bottom points and any free point of the sterilization chamber in real time, a temperature controller is used to display the temperatures and a timer is used to control the work of the steam generator. The sterilization temperature is maintained for a preset sterilization time, then high pressure steam which is inside the sterilization chamber is discharged, the next sterilization cycle is started automatically after natural cooling , and the procedure continues until a preset number of sterilization cycles are completed. The device is capable of holding or hanging the to-be-tested equipment using a minimum load contact area, is capable of finishing the detection of corrosion resistance and sterilization resistance of dental equipment automatically, and is capable of monitoring temperatures in the sterilization chamber and in the vicinity of the EUT in real time, and is capable of freely selecting an interval for naturally cooling the EUT.
Description
Technical field
The automatic test device that the present invention relates to gear division equipment decay resistance and anti-sterilization ability test use is a kind of programme controlled high pressure steam sterilization process acceleration test apparatus.
Background technology
Decay resistance refers to should be without obvious evidence of corrosion according to gear division equipment surface after steam method test in YY 0149 standard, anti-sterilization ability refers to should be without apparent damage according to gear division functions of the equipments after pressuresteam sterilization in YY 1045 and YY 0836 standard, and performance should be without obvious reduction.These two tests are aging tests that the reusable gear division equipment of simulation (such as dentistry air motor, electro-motor, high-speed air turbine mobile phone, straight handpiece and contra-angle handpiece etc.) tolerates repeatedly pressuresteam sterilization in normal service life.
Method of pressure steam sterilization is the conventional sterilizing methods of stainless steel gear division equipment, conventionally more than adopting the lower 134 ℃ of sterilizing 3min of 0.22MPa pressure, also 121 ℃ or the 126 ℃ times that sterilizing is longer of employing that have, according to State Food and Drug Administration's industry standard that issue is implemented successively since 2008, reusable gear division equipment should be able to tolerate the pressuresteam sterilization test of 10 times～250 times under rated condition.
There is no at present the ageing oven of gear division device-specific, there is following shortcoming in usual pressure steam sterilizer or universal ageing oven: volume is large, and temperature, pressure uniformity and stability are wayward; Load frame and gear division equipment contact area are large, and decay resistance test exists blind area; Aging program is generally continuous constant temperature normal pressure program, or needs operating personnel to get involved start-up routine repeatedly, and the test period is long.
Summary of the invention
The object of the invention is to solve the problem that there is no at present the ageing oven of gear division device-specific, a kind of gear division equipment that is applicable to is provided, the particularly special-purpose ageing oven of motor and mobile phone, be gear division equipment corrosion resistance and anti-sterilizing automatic test device, this device can, according to different sterilising temp-time-program(me)s and forevacuum requirement, automatically complete 10～250 sterilization cycle within the shortest time.
Gear division equipment corrosion resistance provided by the invention and anti-sterilizing automatic test device, comprise airtight sterilization chamber, in sterilization chamber, be provided with for suspending or put the load frame of tested equipment in midair, sterilization chamber sidewall is provided with steam inlet, steam inlet connects steam generator, steam generator connects purified water water tank or purified water disposal system by purified water connecting interface, sterilization chamber top is provided with temperature sensor interface, this interface in-0.1MPa～+ 0.35MPa pressure limit without leaking, temperature sensor enters in sterilization chamber by this interface, and be arranged in the tested equipment placed in sterilization chamber before, after, on, lower 4 and a free point, temperature sensor is connected to temperature detect switch (TDS), temperature detect switch (TDS) and steam generator are connected to PCL controller.
Load frame provided by the invention can adopt puts and suspends two kinds of modes in midair and place tested equipment, to tested equipment (EUT) is placed in sterilization chamber.The tested equipment of described load frame suspention comprises dentistry air motor, electro-motor, high-speed air turbine mobile phone, straight handpiece and contra-angle handpiece, and the tested equipment that load frame is put comprises dentistry rotation apparatus and operating theater instruments.
Operating personnel can be on guidance panel preset sterilising temp, sterilization time, interval time and sterilising cycle number.Steam generator is from purified water water tank or the water intaking of purified water disposal system, produce steam and send into sterilization chamber by steam inlet, before the interior tested equipment of temperature sensor Real-Time Monitoring sterilization chamber, after, on, near the temperature of the free point (being generally EUT) that lower 4 and operating personnel arrange, after all monitoring point temperature all reaches setting value, temperature detect switch (TDS) enters discontinuous operation keeping warm mode by PCL controller control steam generator, sterilising temp in sterilization chamber continues after preset sterilization time, discharge the high pressure steam in sterilization chamber, naturally be cooled to after preset interval time, automatically start next sterilising cycle, until complete preset sterilising cycle number.
advantage of the present invention and good effect:
The present invention can complete the test (10～250 sterilising cycles) of corrosion resistance and anti-sterilizing by unmanned automatically to gear division equipment, can freely select interval time naturally cooling for EUT, near temperature in can Real-Time Monitoring sterilization chamber and EUT, can put or suspend in midair EUT to reduce EUT and load frame contact area.
