Description
Technical field
Field of medical device is the utility model is related to, is a kind of device being used for from biological specimen collection cell, is specifically
A kind of cell collection device.
Background technology
One of forward position of current early diagnosis of cancer and monitoring development is how to be entered using blood, urine or other body fluid
Row cancer diagnosis and examination.The maximum advantage of the technology is：Noninvasive detects, and early stage efficient diagnosis cancer can occur in cancer
Disease and can Reusability in a short time, so as to realize immediately monitoring.In addition, it avoids patient from receiving unnecessary live body inspection
Look into, testing cost is also relatively cheap, is advantageous to extensive use clinically.With the development of science and technology, this is detected in recent years
The degree of accuracy and sensitivity of technology have greatly improved.But how extremely micro cancer cell from a large amount of body fluid it is easy,
Quickly separating is current research person endeavours the problem of to be solved.
In the past cell was collected using the method for traditional centrifugation.The cell that need to be collected is put into test tube, it is conventional from
The heart, but find some shortcomings through long-term clinical practice：Concentrated reflection is after test tube centrifugation, the when of falling supernatant, once not
Totally, need to take back and forth.Such result causes the cell being fully enriched with after centrifugation, in taking repeatedly
Cheng Zhong, and be mutually mixed with remaining liquid (because supernatant is by manual operation, it is impossible to fall very clean), and make through centrifugation
The cell of concentration is watered down once again.Supernatant is removed every time, can all lose cell, the cell quantity for causing to finally give subtracts significantly
It is few, sample validity and positive clinical rate are reduced, and greatly increase the working strength of experimenter.Moreover, this method without
Method separates different types of cell.
In view of this, a kind of appearance of cell harvestor easy to operate, reducing labor intensity is with regard to necessary.
In order to analyze cell, it is often necessary to separate and collect cell from biological specimen.For example, in order to diagnose
And/or treatment some diseases, it may be necessary to so do.For example, the analysis of the cell extracted from urine specimen can be used for diagnosing
Carcinoma of urinary bladder, or the cell separated from excrement can be used for the cancer of diagnosis intestines and stomach.
Conventional is that cell is collected from fluid sample using centrifugal force, and the power that wherein high speed centrifugation power is applied causes sample
Larger, thicker particle is settled out in this.Typically, larger particle includes the cell material being included in sample, and it is
Separated with the fluid composition of sample.Once cell material has obtained, then can using microscope or other analysis methods come pair
It is analyzed.
During centrifugal treating, biological specimen and the cell material being included in are subjected to significant forces.These power can be led
Cause the damage of cell material, such as cell rupture.This can influence obtained result, and/or cause when the extracted material of analysis
It is difficult to complete diagnosis during material.
Further, since the needs to special equipment, it is often necessary to which biological specimen is sent to remote laboratory so as to reality
Apply centrifugation and analysis.Cell material in biological specimen is degraded with the time, is obtained between sample and analysis sample
Any delay can cause analyzed material to become to damage.This can influence obtained result, and/or make it difficult to make diagnosis.
Therefore, for using needing sample being sent to remote laboratory to carry out the necessity of the special equipment of point analysis of variance
It is undesirable, because delay is imported into the process, therefore increases the risk that extracted cell degenerates.
Therefore, accurately diagnosed to optimize the quality of extracted cell material and can make, it is necessary to which a kind of minimize
The method that cell is collected from fluid sample of damage is caused to cell.
Pleural effusion is common clinical, and the common cause of disease has a lot, such as cardiovascular disease, hepatopathy, peritoneopathy, kidney
Disease, dystrophia disease, the transfer of malignant tumour peritonaeum, ovarian neoplasm, connective tissue disease etc., disease form pleural effusion and are excessively
As Pleural effusions.Pleural effusions inspection be used clinically for by check the property of Pleural effusions determine Pleural effusions formation the reason for and
The cause of disease, the treatment to clinical disease play directiveness.
Pernicious Pleural effusions refer to because the malignant tumour or cancerous lesion that occur in whole body or splanchnocoel cause thoracic cavity, abdominal cavity
Lamina visceralis pleuroperitoneum occurs diffusivity lesion and causes the phenomenon of cavity fluids abnormal increase, therefore clinically in the chest and abdomen of extraction
Cancer cell is found in water to be to patient's progress cause of disease determination and takes the premise effectively treated in time.Generally Pleural effusions are big
Thousands of milliliters are there are about, and clinically often outwards extract 5~10ml Pleural effusions censorship at random with drainage tube；However, due to
In initial stage of cancer, cancer cell number is less, therefore occurs and fail to pinpoint a disease in diagnosis phenomenon, so that delay conditions of patients.

The cell mass by centrifuging the oval column type being molded is poured out, carries out corresponding subsequent experimental processing.
It is described above simply to illustrate that the principle of the utility model.Further, since this utility model operating technology
Dexterity easily causes the utility model to produce many changes, and any one skilled in the art is new in this practicality
In the technical scope that type discloses, the change or replacement that can readily occur in should all be covered within the scope of protection of the utility model.
The content not being described in detail in this specification belongs to prior art known to professional and technical personnel in the field.
