Description
Technical field
The present invention relates to medicine technology fields, and in particular to a kind of urine preserves liquid, preparation method and its pelletizer.
Background technology
Urine is the excreta being of great significance, the variation reflection urinary systems of urinary fractions and its hetero-organization organ
The accuracy of lesion, testing result is directly related to the Clinics and Practices of disease.Urine cytology inspection is for finding to secrete
A kind of pathological examination method of urinary system malignant tumour.
Urine is a kind of unstable substance, will occur certain chemical changes once discharge, store 6h, 12h and for 24 hours after
Inspection result and sample when rigid discharge it is different, main reasons is that the corruption of urine sample, tangible or nothing occurs for when urine corruption
The variation of shape, pH value may increase or reduce, color burn, smell is rancid, turbidity increases, bilirubin is reduced or disappears, ketone
Body is reduced or is disappeared, glucose in urine is reduced or disappears, urobilinogen is reduced or disappear, bacterium increases, mould increases, cast reduces or disappears
It loses, red blood cell dissolves and deformation, occult blood enhancing, albumen can increase or decrease, nitrite false positive, ammonia increase, vitamin subtracts
It less or disappears, this series of variation all damages urine cellular morphology.Urine currently on the market preserves liquid, in fixation
Urine cell keeps eucaryotic cell structure stability bad, and the retention time is not grown, and more than three days cells are perishable at room temperature, and
It all uses 40% methanol addition formaldehyde as fixed preservative, easily causes the agglomerating caking of cell, also easily caking is heavy for protein mucus
It forms sediment, is unfavorable for the dispersion and observation of cell.
When urine detection, after first acquiring freshly voided urine, urine is added and preserves liquid, tumour and non-tumor cell is made to keep
Initial cell form when acquisition, and so that cell is uniformly coated on glass slide by film-making and thin-layer cell smear is made, it dyes
Eucaryotic cell structure is clearly easily debated under the microscope afterwards.
Invention content
The purpose of the present invention is to provide a kind of urines to preserve liquid, preparation method and its pelletizer, existing to solve
Urine preserves liquid and there is the problems such as fixed urine cell, keep urine eucaryotic cell structure stability poor.
To achieve the above object, the technical scheme is that：
A kind of urine preserves liquid, including following components is by mass percentage：Sodium citrate 2%~4%, sodium chloride
0.08%~0.12%, potassium chloride 0.03%~0.05%, calcium chloride 0.02%~0.03%, formaldehyde 20%~30%, ethyl alcohol
30%~40%, glacial acetic acid 1%~2%, surplus are distilled water；It is the key component for fixing urine cell with formaldehyde and ethyl alcohol,
It can quickly macrocyclic fixed preservation urine cell, urine cellular morphology remain intact, meet urine test to effective cell
The requirement of quality and quantity, while formaldehyde can kill the microbial impurities in urine, have bacteriostasis, it can be ensured that urine sample
Product do not go mouldy during preserving, and do not influence film-making observation as a result, ethyl alcohol has fixed dehydrating agent and disinfectant effect, and substantially
Human body will not be damaged, the methanol that urine preservation liquid contains on the market is solved at present and testing staff's actual bodily harm is asked
Topic, sodium chloride, potassium chloride and calcium chloride are used as buffer solution, keep urine Premeabilisation of cells pressure stabilization, will not expand, pyknosis etc.
Metamorphosis, prevents urine cell rupture, and sodium citrate is added as stabilizer, prevents the epithelial cell to fall off in urine and in vain
Cell degradation is agglomerated, and urine sample detection is influenced, and glacial acetic acid is used for adjusting the pH value that urine preserves liquid, ensures that the biology of urine is living
Property；
Further, it includes that following components is by mass percentage that the urine, which preserves liquid,：Sodium citrate 2.4%, chlorine
Change sodium 0.10%, potassium chloride 0.04%, calcium chloride 0.02%, formaldehyde 26%, ethyl alcohol 36%, glacial acetic acid 1.5%, distilled water
33.94%；
Further, the pH value that the urine preserves liquid is 6.5~7.4；
Further, the mass concentration of the ethyl alcohol is 95%~100%, the mass concentration of the formaldehyde is 35%~
45%；
A kind of urine preserves the preparation method of liquid, includes the following steps：
A. sodium chloride, potassium chloride and calcium chloride are weighed by formula ratio, is put into mixer and is uniformly mixed；
B. the distilled water of formula ratio, stirring and dissolving are added into mixture obtained by step A；
C. the formaldehyde and ethyl alcohol of formula ratio are added into step B acquired solutions, is stirred to obtain mixed liquor；
D. the sodium citrate of formula ratio, stirring and dissolving mixing are added in the mixed liquor obtained by step C；
E. the glacial acetic acid stirring and dissolving of formula ratio is added into step D acquired solutions, adjusts pH value.
It is a kind of to preserve the pelletizer that liquid prepares urine test sample, including flat-ended tube, pipe lid and coverslip using urine,
The coverslip is lain in a horizontal plane in flat-ended tube, and the pipe lid is connected with the upper, open end of flat-ended tube by screw thread, is conveniently taken
Put urine sample；
Further, the material of the flat-ended tube is transparent glass or plastics, facilitates color, the turbidity of observation urine sample
Material Deng, the pipe lid is plastics；
Further, the volume of the flat-ended tube is 50ml, a diameter of 30mm, a diameter of 28mm of the coverslip, lid
Slide can be conveniently placed in flat-ended tube；
Further, it is equipped with scale on the outside of the tube wall of the flat-ended tube, conveniently measures the volume of urine sample.
The thin-layer cell smear that urine sample is made using above-mentioned pelletizer, is included the following steps：
A. the pipe lid is opened, urine is packed into flat-ended tube and preserves liquid and the mixed urine sample of freshly voided urine, lid
The good pipe lid；
B. the flat-ended tube is put into centrifuge, is centrifuged 5 minutes under the acceleration of gravity of 2000G；
C. the coverslip in the flat-ended tube is taken out, progress urine cytology test experience in flat ware is put into.
The invention has the advantages that：
1, urine of the present invention preserves the enough quickly macrocyclic fixed preservation urine cells of liquid energy, and urine cellular morphology has been kept
It is good, meet requirement of the urine test to effective cell quality and quantity, while formaldehyde can kill the microbial impurities in urine,
With bacteriostasis, it can be ensured that urine sample does not go mouldy during preserving, and does not influence film-making observation as a result, ethyl alcohol has fixation
Dehydrating agent and disinfectant effect, and human body will not be damaged substantially, it solves at present urine on the market and preserves what liquid contained
The problem of methanol is to testing staff's actual bodily harm, sodium chloride, potassium chloride and calcium chloride keep urine Premeabilisation of cells as buffer solution
The stability of pressure will not expand, the metamorphosis such as pyknosis, prevent urine cell rupture, and sodium citrate is added as stablizing
Agent prevents the epithelial cell to fall off in urine and leucocyte from degrading and agglomerates, and influences urine sample detection, and glacial acetic acid is used for adjusting urine
Liquid preserves the pH value of liquid, ensures the bioactivity of urine.
2, raw material used in urine preservation liquid of the present invention is simple and easy to get, of low cost, convenient for promoting the use of, preparation method
Simply, three-waste free pollution generates, and does not generate the medical waste for needing specially treated in use.
