example 1

[0030] After the specimen is collected, it is placed in a preservation solution bottle, shaken for 15 minutes, and then placed in a cell densitometer for density measurement. , as well as the specific value of the cell density and the required sample volume. Manually add samples according to the amount of samples indicated, and add them into the funnel of the centrifugal rotor. Below the funnel is the glass slide. After fixing it with a snap ring, start centrifugal production in the centrifugal film maker. After 10 minutes, the slides are made. After staining, it can be examined under a microscope. Specific steps are as follows:

[0031] 1. Take the bottle of preservation solution that has taken the sample, tighten the cap and put it on the shaker evenly. Adjust the speed to 5000 rpm and the time to 15 minutes, and the machine can automatically oscillate and stop.

[0032] 2. Mix the oscillated specimen manually before putting it into the cell density meter, put it into the...

Abstract

The invention relates to a system and a method for manufacturing flakes of liquid-based cytology. The system comprises an oscillator, a cell densitometer and a centrifugal flake-manufacturing machine, wherein the cell densitometer comprises a turbidity sampling component for measuring the turbidity of a sample, an input-output control device for receiving signals from the turbidity sampling component and performing data processing on a mainboard, an output device for outputting measurement data, a power supply, and an input device for inputting data or instructions. The system for manufacturing the flakes can ensure that the cell amount on a slide is invariable and make cells flatly spread on the slide evener and more laminar; the cells have original forms which actually reflect the problems of pathological changes and the like at the cervix or other parts of a patient and are more advantageous for a pathology doctor to diagnose; and the instrument has a simplified design structure for the convenience of operating and maintaining, and prolonging the service life. The invention also discloses the method for making the flakes by adopting the system.

Description

technical field [0001] The invention relates to a liquid-based cytology sheet-making system in the field of medical devices, in particular to a liquid-based cytology sheet-making system integrating cell density measurement and centrifugal sheet-making. Background technique [0002] Cervical cancer, as a high-incidence gynecological malignancy, ranks second in female cancer deaths. According to statistics, about 53,000 women die of cervical cancer in my country every year. The detection rate of traditional Pap smears for various precancerous lesions is only 15%, causing a large number of patients to lose the opportunity of early diagnosis and early treatment. At present, the traditional Pap smear is replaced by liquid-based cytology detection technology, that is, TCT (cervical liquid-based thin-layer cytology test) technology has replaced the traditional gynecological examination cervical smear (Pap smear) technology, and has become The highest standard for measuring the lev...
