Description
Technical Field
The invention belongs to the technical field of medical equipment, and particularly relates to an integrated hydrogen peroxide low-temperature plasma sterilization ultra-fast biological reader.
Background
The quick biological indicator is a special living microbe product, and can be used for confirming the performance of sterilization equipment, verifying sterilization procedure, monitoring sterilization effect in production process, etc. When the supply room uses the sterilizer to sterilize articles, the sterilizer is filled with the extremely-rapid biological indicator, the indicator is subjected to biological culture after sterilization, the culture time is 30 minutes, and the sterilized articles can be dispensed after the biological culture is qualified.
Before the ultra-fast biological indicator is cultured, an upper indicator cover needs to be manually pressed down to crush the ampoule bottle inside the indicator, the indicator is swung, so that a culture solution in the ampoule bottle contacts a fungus piece in the indicator, the situation that the ampoule bottle is not broken or is difficult to crush by manual pressing often occurs in actual operation, the situation that the culture solution is forgotten to be uniformly thrown after the ampoule bottle is crushed, the fungus piece cannot fully contact the culture solution is also crushed, and therefore the situation that sterilization monitoring fails is caused.
The cultivation of the extremely fast biological indicator needs an extremely fast biological reader, the extremely fast biological reader is an independent product at present, is separated from a sterilizer, and is used for carrying out turnover cultivation on the indicator after the monitoring of the extremely fast biological indicator is completed and the sterilization is needed, so that the labor cost and the probability of indicating secondary pollution in the turnover process are increased.
The hydrogen peroxide low-temperature plasma sterilizer is one sterilizer for sterilizing surgical instruments in hospital. The hydrogen peroxide low-temperature plasma sterilizer is used for sterilizing through hydrogen peroxide low-temperature plasma, and various microorganisms on medical instruments and surgical instruments are inactivated through a specific mode in the sterilization process, so that the sterilization purpose is achieved; the integrated 48-hour ordinary biological reader cannot observe the monitoring result through a display screen. The cultivation of the extremely fast biological indicator needs to be completed on an independent extremely fast reader, and the culture solution in the indicator needs to be manually crushed and evenly thrown up manually. The specific technical problems are as follows:
(1) the culture mode of a 48-hour common integrated biological reader is adopted, the detection efficiency is extremely low, the sterilization result can be checked after 48 hours after sterilization, and the sterilization result can be checked only by 30min after the sterilization by an extremely-fast reader.
(2) The method for manually crushing the ampoule bottle in the extremely fast biological indicator is adopted, the operation is time-consuming and labor-consuming, and the condition that the ampoule bottle in the extremely fast biological indicator cannot be crushed or is difficult to crush often occurs; the operation method for manually throwing and homogenizing the culture solution after the ampoule bottle is crushed has the problems of poor effect, uneven contact of the bacterial slices with the culture solution and frequent forgetting of throwing and homogenizing of clinical operators.
(3) After the sterilization of the ultra-fast biological indicator is finished, the ultra-fast biological indicator needs to be transferred to a separate ultra-fast reader device for cultivation, which wastes manpower and time and increases the probability of secondary pollution of the ultra-fast biological indicator in the transfer cultivation process.
(4) Two devices are needed to sterilize and monitor the articles, and the occupied economic cost, time cost and space cost of the sterilization and disinfection supply room are high.

The integrated hydrogen peroxide low-temperature plasma sterilization ultra-fast biological reader further comprises a front cover, and the incubator body is fixed with the front cover through a mounting panel.
Preferably, the bottom cooperation of fixing base install the shock pad, avoid fixing base more stable through the shock pad.
The extremely fast culture system is in communication connection with a display screen of the reader, so that the culture result of the extremely fast biological indicator can be directly observed on the display screen of the equipment.
When the rapid biological indicator is used, the rapid biological indicator is placed in the fixed seat, then the speed reduction motor is started, the speed reduction motor rotates to drive the compression rod to rotate and press down, the lower limit position of the compression rod is controlled by the limit switch, the cover of the rapid biological indicator is just pressed down when the compression rod rotates to the lower limit position, the ampoule bottle inside is crushed, and after the crushing action of the rapid biological indicator is completed, the speed reduction motor rotates to drive the compression rod to rotate back, and the rotation is controlled by the limit switch to return to the initial position; starting a vibration motor to start high-speed rotation work at the moment, driving the fixing seat and the ultra-fast biological indicator on the fixing seat to vibrate, achieving the effect of fully contacting the internal culture solution with the fungus pieces through high-frequency vibration of the ultra-fast biological indicator, putting the ultra-fast biological indicator into the culture seat to be cultured after crushing and vibrating, communicating the culture system with a display screen of the equipment, sharing the display screen, and observing the culture result of the ultra-fast biological indicator on the display screen of the equipment.
Compared with the prior art, the invention has the following beneficial effects:
1. the invention integrates the crushing and vibrating system and the extremely fast culture system into an incubator body, and the incubator body is fixed with the front cover of the sterilization equipment, thereby realizing the integrated extremely fast biological reader, being convenient and safe to operate, realizing crushing and vibrating the indicator on the sterilizer, simultaneously culturing the extremely fast biological indicator on the equipment, viewing the monitoring information by sharing the display screen of the equipment, greatly improving the sterilization monitoring efficiency, and avoiding the repeated transfer culture after the extremely fast biological indicator is sterilized.
2. After the sterilization of the ultra-fast biological indicator is finished, the ultra-fast biological indicator does not need to be transferred to a separate ultra-fast reader device for cultivation, the sterilization monitoring efficiency is improved, and meanwhile, the condition of secondary pollution of the ultra-fast biological indicator in the transfer cultivation process is avoided.
3. The ampoule bottle in the extremely-fast biological indicator can be automatically crushed and uniformly vibrated, the problem that the ampoule bottle cannot be pressed or is difficult to press is solved, meanwhile, the automatic vibration function after being crushed replaces manual swing, the problem that the effect of manual operation of a culture solution is poor is avoided, and the fungus pieces can be cultured under the condition of fully contacting the culture solution.
4. The invention has high monitoring efficiency, and can obtain a monitoring result after culturing for 30min, thereby greatly improving the use efficiency of the sterilization apparatus.
