Abstract
The present invention relates to a test card for detecting concentration of glutaraldehyde. Its production method includes the following steps: using sulfite, amino acid and additive to treat test paper in steps, drying and cutting to obtain strips, sticking the test strip on the base material so as to obtain the test card. When it is used, the test card can be dipped into the sample, if the test card surface is uniformly become yellow, it shows that the concentration of the glutaraldehyde is reached to standard value.
Description
Technical field: the chemical test paper that the present invention relates to glutaraldehyde content test in a kind of glutaraldehyde water solution.
Background technology: glutaraldehyde water solution is widely used in the medical equipment sterilization, wherein, 2% glutaraldehyde water solution is considered to economical and effective the most, in the sterilization process, glutaraldehyde is constantly consumed, when its concentration is lower than 2%, in the equal processing time, bactericidal effect is difficult to guarantee, the necessary corresponding prolongation processing time.So the concentration that medical institutions need often to measure the glutaraldehyde germifuge to be guaranteeing bactericidal effect, the concentration range of normal mensuration is between 1.0%-2.2%.The user of now a lot of glutaraldehyde disinfectants generally adopts the method for chemistry titration to obtain its concentration, to determine bactericidal effect.Do to obtain more accurate concentration numerical value like this, but required time is long, prior preparation relevant criterion solution, complex steps, and the titration operation person also had certain technical quality requirement.
Summary of the invention: in order to overcome above deficiency, can measure the concentration range of glutaraldehyde rapidly intuitively, guarantee the bactericidal effect of glutaraldehyde disinfectant, we have developed the glutaraldehyde concentration test card.According to relevant bibliographical information, glutaraldehyde has a critical nature: when sulfite solution existed, glutaraldehyde and amino acids reacted and displaing yellow.We are through a large amount of tests, selected sodium sulphite and glycocoll (or lysine), regulate the two ratio and concentration and add suitable catalyzer, make mother liquor, handle test paper then, treated test paper adsorbs certain amount of stabilizer again, through oven dry or air dry below 60 ℃, shear forming again is fixed on the ground that does not absorb water with viscose glue or double faced adhesive tape, can obtain the glutaraldehyde concentration test card.Accurately control and adjusting mother liquor composition and treatment conditions can make the series of tests card to the variable concentrations range-sensitive, are used to test the glutaraldehyde water solution concentration of different range, 1.0%-2.2% concentration range particularly pharmaceutically commonly used.During test, only need test card evenly adhesional wetting rapidly in the glutaraldehyde water solution that desire is surveyed, cross the change color that to observe test card in 4-8 minute, if evenly flavescence, prove that then glutaraldehyde concentration has reached the concentration scale that test card indicates in the solution, nondiscolouring or variable color not exclusively then indicated concentration do not reach the concentration scale that test card indicates.It is very convenient to operate, and the result is also more accurate, can satisfy the requirement of disinfection to the glutaraldehyde concentration precision fully, and the operator is not had any special technical requirement, can intuitively assess the sterilization conditions of used glutaraldehyde disinfectant rapidly.
Embodiment: accurately prepare sodium sulphite and glycocoll (or lysine) aqueous solution of 0.1-2.0M, placing spends the night makes it stable, and the catalyzer that adds preparation in advance mixes for 1 part, and this catalyzer is organic compound of polysaccharide.A test paper is immersed in this solution fully, make the evenly chemical constitution in the absorbent solution of test paper every shaking container in several minutes, soak after five to six hours, test paper is taken out gently, 60 ℃ of oven dry or air dries down, after treating to parch fully, test paper is put into the stabilizing agent that has prepared again and soaked into, this stabilizing agent is the inorganic nano grade silicon material.Take out drying then rapidly, cut into blockage, be fixed on viscose glue or double faced adhesive tape on the ground that does not absorb water, this ground is film or plastic sheet normally.The convenient change color of observing can be coated the frame of dark color (being generally black) at the edge of test paper in order to test, and can make with glutaraldehyde water solution concentration 2.0% like this is the glutaraldehyde concentration test card of critical value.Show that with this card actual measurement when glutaraldehyde concentration reached 2.0%, test card bedewed in back 4-8 minute by the even flavescence of white; When glutaraldehyde concentration less than 2.0%, it is yellow that the test card adhesional wetting part only occurred in 4-8 minute, and promptly flavescence is inhomogeneous; When glutaraldehyde concentration far below 2.0% the time, nondiscolouring in test card adhesional wetting 4-8 minute.
Regulate the concentration and the proportioning of sodium sulphite and glycocoll (or lysine), and change catalyst consumption,, can make series of tests card different glutaraldehyde concentration sensitivities with same PROCESS FOR TREATMENT test paper.
Claims (9)
1, uses sodium sulphite and glycocoll (or lysine) to handle test paper, make the glutaraldehyde concentration test card.
2, sodium sulphite and glycocoll (or lysine) are formulated as the aqueous solution of 0.1-2.0M in the claim 1.
3, the concentration determination that the glutaraldehyde concentration test card that makes is used for medical glutaraldehyde disinfectant.
4, the concentration range that the glutaraldehyde concentration test card is measured in the claim 3 is 1.0%-2.2%.
5, regulate the proportioning and the concentration of sodium sulphite and glycocoll (or lysine), change the test specification of glutaraldehyde concentration test card, this scope is meant 1.0%-2.2%.
6, test paper is fixed on by viscose glue or double faced adhesive tape makes the glutaraldehyde concentration test card on the ground that does not absorb water.
7, after test paper process sodium sulphite and glycocoll (or lysine) aqueous solution soaking, be lower than oven dry or air dry under 60 ℃ of temperature.
8, determine the concentration range of glutaraldehyde by observing glutaraldehyde concentration test card change in color.
9, change color is meant flavescence, not flavescence or inhomogeneous flavescence in the claim 8.
