Tumor screening system, collection vial for liquid based cytology, brush for liquid based cytology of cervix carcinoma and supporting solution for cytological diagnosis

Abstract

Disclosed are a tumor screening system, which operates separation of cells from a vial containing a solution mixed with the cells and collection of the cells on a slide using an automatic unit, a collection vial for liquid based cytology serving to simultaneously store a solution containing cells and pour the solution from out of tumor screening system, a brush for liquid based cytology of cervix carcinoma, which collects cells from a woman's uterus, and a supporting solution for cytodiagnosis, which preserves the collected cells.

Description

technical field [0001] [01] The present invention relates to a tumor screening system, a collection bottle for liquid-based cytology detection, a brush for liquid-based cytology detection of cervical cancer, and an auxiliary tool for cytological diagnosis solution. This tumor screening system uses an automated unit to separate cells from a vial containing a solution mixed with the cells and collects the cells on a glass slide, and a collection bottle for liquid-based cytology testing is used to simultaneously store the solution containing the cells and Pour the solution out of the tumor screening system. A brush for liquid-based cytology testing of cervical cancer helps collect cells from a woman's uterus. Auxiliary solutions for cytological diagnosis include a buffer, which stores the collected cells under the condition of maintaining the collected cells within a specified pH range; alcohol, which is used to suppress protein denaturation of cells to maintain the pathologica...

AI Technical Summary

Problems solved by technology

[0020] [20] The "device for collecting cervical cells" disclosed in reference 2 has the advantage that the length of the device is adjustable, but its disadvantage is that the cell collection only relies on the collection brush prepared in the first collection unit, Therefore, the cell collection efficiency cannot be guaranteed

However, since the amount of alcohol used to fix the cells is 45-55 parts by weight, preferably 50 parts by weight, the cell preservation solution disclosed in US Pat. No. 5,256,571 is still flammable

Furthermore, cell preservation solutions have low red blood cell removal rates and can only preserve cells for a relatively short period of time (approximately 3 months), making DNA extraction from cells difficult
