Abstract
The invention belongs to medical apparatus and instruments design and fabrication technology field.
The present invention is used for the automatic control of autoclave sterilizer.The major technique feature is two: one is directly temp autocontrolled, principle of automatic control in the steriliser to be had nothing to do with steam pressure.Directly do not control steam pressure, temperature control is accurate, and the temperature control scope is at will adjusted according to the sterilization needs.Another is automatic control during to perseverance, promptly just begins the time automatic control of calculating when temperature reaches desired numerical value in the steriliser.Scope is arbitrarily adjusted when controlling as required.
The self-con-tained unit using method: earlier two push switch are clicked simultaneously, and then open K switch, order can not be put upside down.
Description
The invention belongs to medical apparatus and instruments design and fabrication technology field.
High pressure steam sterilization is a kind of traditional good sterilizing methods, and still, high pressure steam sterilization equipment changes not quite for many years, and the portable high-pressure steam sterilizing pan that has through commonly used belongs to small-sized; Vertical high-pressure steam sterilizing pan belongs to medium-sized; Horizontal high-pressure steam sterilization pot belongs to large-scale.During sterilization, all to can not reach full automatic control basically by Artificial Control.Please referring to relevant chapters and sections of sterilizing in institution of higher learning's microorganism class teaching material.Hold as the model show, Shen Ping, 1980, institution of higher education tries out teaching material books such as " microbiology experiments ".
The objective of the invention is to design and produce a kind of full self-acting controlled high pressure steam sterilizer.
Through test of many times, I have manufactured experimently a self-acting controlled high pressure steam sterilizer.Through on probation, functional.This self-acting controlled high pressure steam sterilizer is made up of a self-con-tained unit and an electric heating autoclave sterilizer (pot) two parts.Self-con-tained unit is mainly by thermoindicating controller, and its temperature-sensing element adopts critesistor; The time relay and a plurality of A.C. contactors etc. are formed automatic control circuit, its profile and principle, and circuit please be seen Figure of description 1 and accompanying drawing 2.Autoclave sterilizer and traditional difference are that a temperature-sensing probe sleeve pipe has been installed on the steriliser lid.About telescopic structure, size, installation is please referring to Figure of description 3 and accompanying drawing 4.Steriliser connects please referring to accompanying drawing 4 with self-con-tained unit.
Two parameters of this self-acting controlled high pressure steam sterilizer to sterilizing: constant temperature, whole automatic controls when permanent.In other words: to desired temperature and the whole automatic controls of homothermic time under this temperature of sterilizing.For example before the sterilization,, just do not need the people to keep an eye on behind the power-on switch then as long as desired Temperature numerical and the time numerical value that keeps under this temperature are imported this machine.After arriving desired constant temperature time, this machine is turned off power supply automatically.For example 121 ℃ and 30 minutes two numerical value are imported this machine, after turning on the power switch, when the temperature in the steriliser reaches 121 ℃, automatically the heating element heater power supply breaks, when being reduced to 121 ℃ under the temperature, automatic again energized makes the temperature that remains at 121 ℃ in the steriliser.When the steriliser temperature reached 121 ℃, the time relay was started working, pick up counting, and when temperature constant arrives 30 minutes 121 ℃ time, equipment disconnected automatically power down source shutdown.As required, can at will change the temperature and time numerical value of being imported.
The characteristics of this self-acting controlled high pressure steam sterilizer:
1. direct temp autocontrolled in the autoclave sterilizer, principle of automatic control and steam pressure have nothing to do.In other words: not by realizing temp autocontrolled indirectly to the steam pressure automatic control.Therefore not only temperature control is accurate, and the temp autocontrolled numerical value of careless as required adjustment.
2. the time numerical value of this machine of input is just to begin to calculate when temperature just has been raised to desired temperature value in the steriliser before the sterilization, and length heat time heating time when reaching this temperature is irrelevant.
3. can know the actual temperature value in the steriliser the instrument from this machine side plate at any time.
4. can be adapted to large, medium and small various autoclave sterilizer.
5. temp-controlling and time-controlling is accurate.At will adjust as required.
Realization the present invention be easier to, and general electrical engineering technician just can assemble a playscript with stage directions self-con-tained unit according to the circuit drawing.
Description of drawings:
1. temperature-sensing probe sleeve pipes in the accompanying drawing 2;
2. temperature-sensing probe;
3. autoclave sterilizer;
4. thermoindicating controller.
J: the thermorelay of thermoindicating controller.
Self-con-tained unit using method: earlier two push switch are clicked simultaneously, and then open K switch.Order can not be put upside down.
Claims (1)
- The technology of the present invention feature is the automatic control to autoclave sterilizer.Direct temp autocontrolled in the steriliser, principle of automatic control and steam pressure are irrelevant, the constant temperature time automatic control that begins to calculate when temperature in the steriliser is reached the numerical value of a certain requirement, the scope of asking for protection: 1. installation temperature-sensing probe sleeve pipe on the steriliser lid; 2. the effect of K switch in the automatic control circuit.Claim: the independent claims of method and the product that directly uses this method to make.
