Inducement be mainly infectious diseases, circulation system disease, cirrhosis and tumour etc., tumor type is mainly non-small cell
Lung cancer, tumor in digestive tract, adenocarcinoma of lung and malignant mesothelioma, it is necessary to carry out diagnosing and treating as early as possible.Clinically commonly use clinical pathology
Technology diagnoses Pleural effusions, and common diagnostic mode is cell smear, and diagnosis susceptibility can reach 78%.But, this
Kind diagnostic method cannot effectively identify metastatic carcinoma and primary mesothelial tumor, seriously affect the clinical therapeutic efficacy of the disease.
The effect for having data to show that using cell block slice and immunohistochemical staining is diagnosed at this stage is ideal.Cell block slice was both protected
Clear Cytological Characteristic is stayed, and is had many advantages, such as, such as: unnecessary aspiration biopsy equivalent damage operation can be reduced, cell block is cut
Operation is simple for piece immunohistochemical staining, sample is easy to save, reusable, is applied to molecular pathology detection with higher
Practicability.
But the preparation method of existing cell block is to be centrifuged Pleural effusions, precipitates sick cell and tissue fragments therein
Concentration, is wrapped with filter paper, and neutral formalin is fixed, is dehydrated, and after paraffin embedding, slice, dyeing, observation, the method is cumbersome,
Step is complicated, is unfavorable for promoting the use of.That urgently develops a kind of easy applicable cell block prepares tool.
Summary of the invention
The present invention provides a kind of disposable tool for the preparation of cell block, solves in cell block manufacturing process,
It is cumbersome, the biggish Pleural effusions of processing capacity are unable to, the problems such as each laboratory method disunity.
To realize above-mentioned technical purpose and the technique effect, the present invention solves above-mentioned ask by the following technical programs
Topic:
A kind of disposable tool for the preparation of cell block, including it is disposable syringe, threeway, unidirectional
Valve, removable filter, disposable infusion set pipe, totally 5 components form.The disposable syringe lower part passes through one
Infusion apparatus pipe connects a threeway；Other two port of threeway respectively passes through an infusion apparatus pipe and connects the identical list in a direction
To valve, wherein a check valve connects an infusion apparatus pipe, for drawing Pleural effusions to be measured, check valve liquid flow direction is flow direction note
Emitter direction；Another check valve connects a removable filter by an infusion apparatus pipe, and the flow direction of check valve is anti-injection
Device direction；The other end of filter connects an infusion apparatus pipe, for discarded Pleural effusions to be discharged；The middle part of the removable filter
One horizontal strainer is set, over-injected device direction one piece of porous polymer materials of horizontal of strainer are close to, is filtered out for collecting
Sick cell.Pleural effusions to be measured are drawn in hand syringes when use, one end of infusion apparatus pipe, and discarded chest and abdomen are discharged in the other end
Water.
In above scheme, hand syringes aspirate Pleural effusions sample to be measured repeatedly, and sick cell will be collected in porous height
In molecular material hole, discarded Pleural effusions will be flowed to by strainer in discarded Pleural effusions receiving bottle.The advantages of the method
It is that can handle the biggish sample of capacity, it is simple and convenient for operation, be easy to universal and push away and without the equipment such as power supply and centrifuge
Extensively.
In order to guarantee that certain appearance is arranged in the volume of porous polymer materials storage sick cell, the removable filter
Product；In order to guarantee that filter effect, strainer set certain diameter, strainer filter opening sets certain diameter, and strainer is apart from filter bottom
Certain distance is set, the porous polymer materials set certain distance apart from filter top, and porous polymer materials are close to
Strainer, porous polymer materials hole set certain diameter, and porous polymer materials set certain altitude, diameter.
Further, the filter settings volume 0.5ml-4ml；Strainer diameter is set as 0.5-2cm, and strainer filter opening is set
Determine 6 μm -20 μm of diameter, strainer is apart from filter bottom set distance 1mm-2mm；The excessively removable filter of porous polymer materials distance
Top set distance 1mm-2mm, porous polymer materials are close to strainer, and porous polymer materials hole sets 100 μm of diameter-
800 μm, porous polymer materials setting height 1mm-3mm, diameter 5mm-20mm.
The advantages and effects of the present invention are:
1, this method thoroughly changes the method that traditional centrifugal process prepares cell block, and sets without power supply and centrifuge etc.
It is standby, it can handle the biggish sample of capacity；
2, the sick cell that this method is collected is stored in porous high molecular material, can be directly taken out, is put into embedding
It is fixed in box, dehydration, waxdip, embedded section.Being wrapped up with filter paper for conventional method is eliminated, which effectively reduces carefully
The preparation step of mass reduces the loss of sick cell, saves complete；
3, the sick cell that this method is collected, dyeing effect is clear as cell smear, operating method and histotomy
It is equally simple.
