Abstract
This is a kind of disinfecting indicator using high-pressure steam that is made of phenylformic acid and succinyl oxide uniform mixture, is encapsulated in transparent glass tube internal indicator fusing time and is thermophile bacteria under 121 ℃ of temperature, whole death times, i.e. all fusings at 12～19 minutes.
Indicator can be by phenylformic acid 20～45 grams, succinyl oxide 0.5-2 gram, and porphyrize all mixes, by being encapsulated in the colourless transparent glass pipe behind every 0.7-1.5 gram compressing tablet.
Description
Disinfecting indicator using high-pressure steam is that a kind of indicator of monitoring autoclaving effect belongs to material or object sterilizing unit technical field.
Autoclaving is strong owing to its penetration power, and sterilising effect is reliable, thereby obtains to use widely at aspects such as health care, food, pharmaceutical industries.Monitoring to its sterilising effect has a kind of gram inditron of wearing, reagent is in 121 ℃ of temperature in the pipe, through fusing in 5～8 minutes, judge sterilising effect with this, still, this fusing time is lower than American Pharmacopeia to the thermophile bacteria heat hardiness specified time, be that the brood cell kills the time, be no more than 19 minutes, also be lower than China its hot death time of thermophile bacteria is decided to be 15～20 minutes regulation, be unfavorable for the monitoring of sterilising effect.
The invention provides a kind of new indicator that is encapsulated in the transparent inditron, fusing time, under 121 ℃ of temperature, all the death times are for demarcating with thermophile bacteria.This inditron monitoring effect is accurate, and is reliable, easy, the easy row of working method, is beneficial to judgement.
Indicator provided by the utility model, its technical spirit shows, reflection sterilising temp and the chemical reagent compressing tablet of time are encapsulated in the transparent Glass tubing, the chemical reagent sheet of compressing tablet is made up of phenylformic acid and succinyl oxide, if chemical reagent fusing time in the inditron was controlled at 121 ℃ in 12～19 minutes, the component of chemical reagent sheet can be controlled to be, phenylformic acid 20～45 grams, succinyl oxide 0.5～2 gram, porphyrize all mixes, form 4～8 millimeters of unilateral diameters by every heavy 0.7～1.5 gram pressing.
This inditron is placed in the monitored Sterilizers, as long as temperature reaches 121 ℃, tablet can melt when the time length reaches 12～19 minutes in the pipe, and it can reflect the temperature of sterilization, can reflect the time of sterilization again, is a kind of indicating unit of synthetic determination.
Accompanying drawing is a most preferred embodiment sterilization inditron synoptic diagram of the present invention.Below in conjunction with accompanying drawing, further narrate its structure.
Chemical reagent sheet (1) is encapsulated in the transparent glass tube (2), and the described transparent glass tube of present embodiment is to adopt 10 millimeters of diameters, 1 millimeter of wall thickness, long 60 millimeters soda glass tubule.Analoids (1) is by phenylformic acid 36 grams, and succinyl oxide 1 gram porphyrize mixing forms 6 millimeters of unilateral diameters, 6 kilograms of analoids hardness by every heavy 0.11 gram pressing.
This indicator is in HCS, and is when temperature is 121 ℃ of fully fusings through 19 minutes, identical with the temperature and time that Thermophilic Bacteria is killed. This indicator tube can be widely used in food, health care, and inspect sterilizing effect was used when pharmaceuticals industry utilized autoclaving.
Claims (2)
1, a kind of disinfecting indicator using high-pressure steam is characterized in that indicator is by phenylformic acid 20～45 grams in the transparent tube in order to be encapsulated in, and succinyl oxide 0.5～2 restrains, and the equal mixed pressure of porphyrize is closed and formed, every heavy 0.7～1.5 gram.
2, inditron according to claim 1 is characterized in that compressing tablet by phenylformic acid 36 grams, and the equal mixed pressure of succinyl oxide 1 gram porphyrize becomes, every heavy 0.11 gram.
