Abstract

The utility model discloses a kind of exfoliated tumor cells sampling drainage bag, comprise drainage bag main body, the liquid outlet of drainage bag main body is provided with clip, and the bottom of described drainage bag main body inner wall is provided with the groove and projection that match; When groove and projection are provided separately, drainage bag inner chamber is an overall chamber; When groove and projection are equipped with, drainage bag inner chamber is divided into the cavity of resorption of epicoele and enrich tumor exfoliative cyte, the volume of cavity of resorption is 5 ~ 10ml.This utility model is by arranging groove equipped mutually and boss at drainage bag inner chamber, drainage bag can be divided into upper and lower two cavitys before sampling, and exfoliated tumor cells can be made to be gathered in cavity of resorption, sample time can be ensured, improve tumor cell recall rate, effectively prevent failing to pinpoint a disease in diagnosis of tumprigenicity ascites pleural fluid, provide Reliable guarantee for patient treats in advance.

Description

Exfoliated tumor cells sampling drainage bag

Technical field

This utility model relates to technical field of medical instruments, particularly a kind of drainage bag for splendid attire ascites pleural fluid.

Background technology

Thoracic cavity and seroperitoneum are frequently-occurring disease and the commonly encountered diseases of clinical respiratory system and digestive system, the common cause of disease has a lot, such as cardiovascular diseases, hepatopathy, peritoneopathy, nephropathy, malnutrition disease, the transfer of malignant tumor peritoneum, ovarian tumor, connective tissue disease etc., disease forms hydrothorax and too much namely becomes ascites pleural fluid.Ascites pleural fluid inspection for by checking that the character of ascites pleural fluid determines the reason that ascites pleural fluid is formed and the cause of disease, plays directiveness effect to the treatment of clinical disease clinically.

Malignant tumor or cancerous lesion that pernicious ascites pleural fluid refers to owing to occurring in whole body or splanchnocoel cause thoracic cavity, abdominal cavity lamina visceralis pleuroperitoneum generation diffuse lesion and cause the phenomenon of cavity fluids abnormal increase, in the ascites pleural fluid extracted, therefore find cancerous cell to be carry out the cause of disease to patient to determine and the prerequisite taking effectively treatment in time clinically.Generally nearly several thousand milliliters of ascites pleural fluid, and adopt drainage tube outwards to extract clinically often, the ascites pleural fluid of extraction is contained in drainage bag; In ascites pleural fluid checking process, need the ascites pleural fluid censorship of taking out 5 ~ 10ml in drainage bag.But, because drainage bag volume is larger, when sampling, when opening the clip below drainage bag, having a large amount of ascites pleural fluid and flowing rapidly into collecting tank, the not only bad control of ascites pleural fluid amount, and it is due at initial stage of cancer, cancer cell number is less, and the effective tumor cell probability therefore flowing rapidly into collecting tank is less, may occur in testing process failing to pinpoint a disease in diagnosis phenomenon, so that incur loss through delay conditions of patients.

Summary of the invention

This utility model technical issues that need to address are to provide a kind of drainage bag be applied in clinical medicine, can carry out sedimentation to the tumor cell in ascites pleural fluid, can take out the appropriate ascites pleural fluid of enriched tumor cell, to improve the recall rate of tumor cell.

For solving the problems of the technologies described above, technical solution adopted in the utility model is as follows.

Exfoliated tumor cells sampling drainage bag, comprise drainage bag main body, the liquid outlet of drainage bag main body is provided with clip, and the bottom of described drainage bag main body inner wall is provided with the groove and projection that match; When groove and projection are provided separately, drainage bag inner chamber is an overall chamber; When groove and projection are equipped with, drainage bag inner chamber is divided into the cavity of resorption of epicoele and enrich tumor exfoliative cyte, the volume of cavity of resorption is 5 ~ 10ml.

Above-mentioned exfoliated tumor cells sampling drainage bag, the inwall of described drainage bag cavity of resorption is wrapped up in epithelial cell specific antibody film.

Owing to have employed above technical scheme, acquired by this utility model, technological progress is as follows.

This utility model is by arranging groove equipped mutually and boss at drainage bag inner chamber, drainage bag can be divided into upper and lower two cavitys before sampling, and exfoliated tumor cells can be made to be gathered in cavity of resorption, sample time can be ensured, improve tumor cell recall rate, effectively prevent failing to pinpoint a disease in diagnosis of tumprigenicity ascites pleural fluid, provide Reliable guarantee for patient treats in advance.

Detailed description of the invention

In order to make technical problem to be solved in the utility model, technical scheme and beneficial effect clearly understand, below in conjunction with drawings and Examples, this utility model is described in detail.It should be noted that specific embodiment described herein only in order to explain this utility model, and be not used in restriction this utility model.

Exfoliated tumor cells sampling drainage bag, its structure as depicted in figs. 1 and 2, comprises drainage bag main body 1, and the liquid outlet of drainage bag main body 1 is provided with clip 3, for opening and turn off the drainage tube below drainage bag, plays release and stores ascites pleural fluid.

The bottom of drainage bag main body 1 inwall is provided with the groove 2 and projection 4 that match, as shown in Figure 2; When groove and projection are provided separately, the as a whole chamber of drainage bag inner chamber, as shown in Figure 1; When groove and projection are equipped with, drainage bag inner chamber is divided into the cavity of resorption 12 of epicoele 11 and enrich tumor exfoliative cyte, as shown in Figure 3, the volume of cavity of resorption is 5 ~ 10ml.The inwall of this utility model drainage bag cavity of resorption is wrapped up in epithelial cell specific antibody film.

When this utility model normally uses, for splendid attire ascites pleural fluid; When needs sampling detects, leave standstill after rocking drainage bag, tumor being departed from the epithelial cell specific antibody film of cell precipitation bottom drainage bag, then by the groove in drainage bag and projection matched together, now just taking off cellifugal 5 ~ 10ml ascites pleural fluid for being enriched tumor in cavity of resorption; Open clip again, can have enough time that the ascites pleural fluid containing most exfoliated tumor cells is put into exfoliated tumor cells collecting tank, substantially increase the recall rate of exfoliated tumor cells, avoid the generation that tumprigenicity ascites pleural fluid fails to pinpoint a disease in diagnosis phenomenon.

The foregoing is only preferred embodiment of the present utility model; be not limited to this utility model; all do within principle of the present utility model and spirit any amendment, equivalent to replace and improvement etc., be all just included within protection domain of the present utility model.
