Abstract
The utility model relates to the technical field of biomedical treatment and provides a gram staining liquid quality control product. The gram staining liquid quality control product comprises a glass slide, wherein the surface of the glass slide is provided with a gram-positive bacterium coating and a gram-negative bacterium coating; the glass slide is a smooth glass slide or a glass slide with one frosted side and one smooth side; a gram-positive bacterium and a gram-negative bacterium are selected from one or two or more strains; the gram-positive bacterium and the gram-negative bacterium are cocci or bacilli or a mixture of the cocci and the bacilli. According to the quality control product provided by the utility model, the time is saved, the operation is simple, the working efficiency of workers is improved, the quality of staining liquid can be detected and the operation of the workers can be supervised.
Description
Technical field
The utility model belongs to bio-medical technology field, particularly a kind of Grain stain liquid quality-control product.
Background technology
Gram staining is differential staining very important in bacteriology, and 1884 Nian You Denmark doctors found.Bacterium is first dyeed through basic-dyeable fibre crystallization, and after iodine liquid coal dyes, with alcohol, decolours, under certain condition, therefore this look of some bacteriums is not divested, and what have is divested, and bacterium can be divided into two large classes: what do not decoloured is Gram-negative bacteria for gram-positive bacteria, decolouring.For observing conveniently, after decolouring, with a kind of orchil, to redye again, positive bacteria is still purple, negative bacterium is by red-dyed.
Gram's stain generally comprises: just dye, mordant dyeing, decolour, redye four steps, concrete operation method is: the making of nacterial smear sample and fixing, with ammonium oxalate crystal violet, dye 1 minute after washing; Add iodine liquid covering painting face and dye 1 minute after washing, and suck moisture with thieving paper; Add 95% alcohol number and drip, and shake and decolour gently, 30 seconds after washings, suck moisture; Rare sarranine dyeing liquor or husky xanthochromia are after 10 seconds, and tap water rinses, dry, microscopy.
Grain stain four step rule effect is fine, but operation more complicated, be difficult to standardization, be difficult to Quality Control, the every operation of staff once will be done nacterial smear sample one time, lose time, and inefficiency, dyeing liquor quality, dyeing time length, staff's operative technique skill level are had to very high requirement, but existing market is without any a ready made nacterial smear sample, while working for staff, directly brings.
Therefore, bio-medical technology field be badly in need of a kind ofly saving time, simple to operate, improve staff's work efficiency, can detect dyeing liquor quality, staff is played to the Grain stain liquid quality-control product of supervisory role.
Utility model content
In order to overcome existing Grain stain complicated operation, to be difficult to standardization, be difficult to the defect of Quality Control, the utility model provides a kind of Grain stain liquid quality-control product, and technical scheme is as follows:
A Grain stain liquid quality-control product, is characterized in that, comprises:
Microslide, surface has gram-positive bacteria and Gram-negative bacteria coating.
As above a kind of Grain stain liquid quality-control product, wherein, microslide is smooth glass sheet.
As above a kind of Grain stain liquid quality-control product, wherein, on one side slide surface has frosted, another side is smooth glass sheet.
As above a kind of Grain stain liquid quality-control product, wherein, gram-positive bacteria is a kind or 2 kinds or multiple bacterial strain.
As above a kind of Grain stain liquid quality-control product, wherein, Gram-negative bacteria is a kind or 2 kinds or multiple bacterial strain.
As above a kind of Grain stain liquid quality-control product, wherein, gram-positive bacteria is coccus.
As above a kind of Grain stain liquid quality-control product, wherein, gram-positive bacteria is bacillus.
As above a kind of Grain stain liquid quality-control product, wherein, Gram-negative bacteria is coccus or bacillus.
The invention has the beneficial effects as follows:
By the Grain stain liquid quality-control product for preparing and the new smear of making carry out just dying simultaneously, mordant dyeing, the process of decolouring, redying, whether expiredly can detect dyeing liquor.
By the Grain stain liquid quality-control product for preparing and the new smear of making carry out just dying simultaneously, mordant dyeing, the process of decolouring, redying, can operating personnel's operation steps, skill level be exercised supervision and be checked.
The present invention simple to operate, save time.
4. the present invention has improved operating personnel's work efficiency, thereby has improved economic benefit, has applicability more widely.
