CN200996018Y - Filter for inspecting uterine-neck cancer cell - Google Patents

Abstract

A filter used to check cervical carcinoma cell has the characteristics that highly precise filtration membrane (1) is fixed on the vinyl plastic cylinder (2).

Description

A kind of cervical cancer cell is learned the inspection strainer

One, technical field

The utility model belongs to medical instruments field, specially refers to a kind of cervical cancer cell and learns the inspection strainer.

Two, background technology

Cervical cancer is one of modal malignant tumour of women.The whole world has 500,000 New Development cervical cancer cases every year approximately, and the Asia is about 380,000, about 150,000 examples of China, and annual about 230,000 women in the whole world die from cervical cancer, and the Asia is about 190,000, China about 80,000.And cytolgical examination is a kind of important means of prevention cervical cancer.

Traditional pap staining and classification application are since over half a century, for the early diagnosis cervical cancer and reduce mortality ratio and made significant contribution, its main method is that the manual cell sample that collector is obtained of doctor is coated on the microslide, through readding the sheet diagnosis behind the pap staining.But up-to-date studies show that, the smear reality that adopts this traditional-handwork method to make has only been collected 20% cell, cell sample more than 80% then remains on the sampling thief and is discarded together, and influence correct diagnosis owing to existing a large amount of red corpuscle, white corpuscle, mucus and the necrotic tissue that comes off etc. on the smear, cause 2%～50% false negative rate.

In view of above conventional sense easily causes most test results inaccurate, wish to invent a kind of more reliable detection method.

Three, summary of the invention

The utility model makes test result more accurate, in order to achieve this end, the technical scheme that is adopted is: the utility model is made up of plastic cylinder and high precision filtering membrane two portions, in clinical use, the doctor still gathers cervical cell sample by usual method, not that it is coated on the microslide by usual method then, carry out rinsing in the bottle that cell-preservation liquid is housed but collector inserted, so just obtained most cell sample, cell sample bottle with the patient is sent to the laboratory again, adopt high precision filtering membrane of the present utility model to carry out filtering separation in the sample after disperseing, significantly reduce blood, vestiges such as the mucus and the necrotic tissue that comes off, so just obtained a ultrafine intact cellular layer, in order to doing further microscopic inspection and diagnosis.The cell concentration of obtaining is big so on the one hand, has got rid of other on the other hand as blood, mucus and the necrotic tissue etc. that comes off, and makes diagnostic result more accurate.

Four, description of drawings

Fig. 1 is the utility model structural representation.(1) is the high precision filtering membrane among the figure; (2) be ethene hydro carbons plastic cylinder.

Fig. 2 is the structural representation of plastic cylinder of the present utility model.(3) are welding groove among the figure; (4) be the circular arc chamfering structure.

Five, embodiment

With reference to Fig. 1, make plastic cylinder with the ethene hydrocarbon materials, the outside dimension of plastic cylinder is 25.0 ± 1.0mm, internal diameter size is 21.5 ± 1.0mm, height dimension is 54.5 ± 2.0mm, one annular welding groove is arranged above cylinder, adopt the circular arc chamfering structure design, can prevent effectively that the film material from stretching or puncture in the welding groove inside top.

With reference to Fig. 2, high precision filtering membrane (1) is lain in the surface of plastic cylinder (2), the high precision filtering membrane is the nucleopore membranes that adopts plastics film to make, diaphragm diameter is 25.0 ± 1.0mm, thickness is 0.19 ± 0.03mm, filtering accuracy is 7.5 ± 0.5 μ m, and filtering membrane is placed not deflection during making, adopts special mould and hot-melt welding machine that diaphragm is welded in the annular welding groove (3) then.

Claims (5)

1, a kind of cervical cancer cell is learned inspection and is used strainer, it is characterized in that high precision filtering membrane (1) is fixed on the ethene hydro carbons plastic cylinder (2).

2, according to the strainer of claim 1 defined, it is characterized in that high precision filtering membrane (1) is the nucleopore membranes that adopts plastics film to make, diaphragm diameter is 25.0 ± 1.0mm, and thickness is 0.19 ± 0.03mm, and the filtering membrane precision is 7.5 ± 0.5 μ m.

3, according to the strainer of claim 1 defined, the outside dimension that it is characterized in that plastic cylinder is 25.0 ± 1.0mm, and internal diameter size is 21.5 ± 1.0mm, and height dimension is 54.5 ± 2.0mm.
