Description
Technical field
The utility model belongs to sterilising effect Authentication devices field, specifically, relates to the biological indication of a kind of Sterilizers sterilising effect demo plant.
Background technology
The hydrogen peroxide low-temperature plasma Sterilizers is current the most advanced a kind of temperature sterilization technology in the world, with other sterilising method, compare, has sterilizing rapid, nontoxic, simple operation and other advantages, high level mainly for medicine equipment is sterilizing, and particularly the accurate medicine equipment of some official jargon classes is sterilizing.
Rules according to hygiene department, quick, correct evaluation need to regularly be made to sterilising effect to the sterilizing device in institute by hospital, thereby judge whether the sterilization ability of sterilizing device can meet the service requirements of hospital, guarantee that it is qualified dropping into the sterilizing of medicine equipment of performing the operation.In this case, the sterilising effect demo plant that just needs a kind of abundant simulating hospital surgical instruments sterilization process.
More existing hydrogen peroxide low-temperature plasma Sterilizers sterilising effect demo plant inventions thoroughly do not solve at also have a lot of problems and the leak aspect operability and authentic simulation two, done.Such as, existing a kind of hydrogen peroxide low-temperature plasma Sterilizers sterilising effect demo plant, the problem solved is to provide a kind of hydrogen peroxide low-temperature plasma Sterilizers sterilising effect demo plant, after adopting gaseous hydrogen peroxide or peroxide plasma body sterilizing equipment sterilizing, its sterilising effect is carried out to the Fast simulation test.The technical scheme of this utility model patent is: this device forms cylindrical or rectangular test cabinet by attached cavity and with the seal cap of cavity, between described cavity and seal cap, linked by screw thread and sealing-ring, the upper holder block and the lower lock block that match at test indoor location outline and test cabinet inner chamber, in the middle of upper lower lock block, reserve and highly be the slit of 1-3mm, test cabinet one end sealing the other end link internal diameter is that slender conduit or the two ends of 1mm all have described conduit.In upper lower lock block, place the chemical knowledge card, the colour-change by the chemical knowledge card judges the sterilising effect of Sterilizers or in tube chamber, places the biological bacteria sheet, by the bacterium sheet, is judged the sterilising effect of Sterilizers by the cultivation results after sterilizing.
This Sterilizers sterilising effect demo plant has three important factors, and one is the lumen device with briquetting, and one is chemistry indication card, and one is biological indication card.Lumen device and chemistry are indicated the cooperation of card and by the cooperation of official jargon device and biological indication card, are realized the checking of whole sterilising effect.
This wherein have this invention of some technology essential factors do not solve or illustrate clear, the sterilization process of simulated medical instrument fully, thus can accurately not make an appraisal to the sterilising effect of Sterilizers, be mainly reflected in:
The firstth, the structure design of lumen device, the design of test cabinet sectional area, need to do according to the intraluminal sectional area of actual medicine equipment, in actual applications, the internal diameter of the two pulmonary branches tracheal endoscope tubular stingers of a lot of children's is generally all in the 2mm left and right, as the portable fiber mirror FI-7BS type of PENTAX self illumination device, super very thin
The tubular stinger endoscope.Be not difficult to find out the practical application of not considering hospital due to the design of sectional area, so it is sterilizing qualified to be just that the sterilising effect demo plant is indicated after Sterilizers is sterilizing, can not illustrate and can carry out sterilizing to the endoscope of the portable fiber mirror FI-7BS type of similar PENTAX self illumination device, and reach sterilizing requirement, in the practical application of hospital, do not possess using value.So from then on see, this invention is not a kind of reliable sterilising effect demo plant.
The secondth, variable color speed and the variable color condition of chemical indicator do not have accurate and detailed description, and go out checking is arranged or the variable color of chemical indicator is described and the sterilizing assurance level of SAL 10-6 between by which type of relation of equivalence, even if chemical indicator variable color can not illustrate that this sterilizing device can reach the sterilizing assurance level of SAL 10-6.So from then on see, this demo plant is not a kind of reliable sterilising effect demo plant.
In addition, biology indication card in this demo plant needs independent taking-up after each sterilizing end, put in nutrient solution and cultivate again, this manipulation require allows biological indication card before cultivating, contact the environment of sterilized, probably cause infection, false positive occurs, disturb sterilizing result.Even if so only the device of this demo plant is after sterilizing, biological indication card cultivation results is positive, and can not illustrate that the sterilising effect of Sterilizers is defective.
Summary of the invention
The technical problems to be solved in the utility model is to overcome above-mentioned defect, and the biological indication of the Sterilizers sterilising effect demo plant of the problems that exist on a kind of simple in structure, reliability of solving the sterilising effect demo plant and actual application value is provided.
For addressing the above problem, the technical scheme that the utility model adopts is:
The biological indication of a kind of Sterilizers sterilising effect demo plant, comprise protective shell, in protective shell, be provided with support, on support, be provided with culturing room, the front end of culturing room is provided with culturing room's upper cover, it is characterized in that: in described culturing room, cover and run through and tubule is installed, culturing room runs through away from an end of culturing room's upper cover and tubule is installed; In described culturing room, be provided with the nutrient solution container, culturing room is provided with biological indicator sheet away from an end of culturing room's upper cover.
Described tubule is that internal diameter is the plastic hose of 1mm.
Between described culturing room upper cover and tubule, be connected by the silica gel adapter sleeve.
