Abstract
The utility model discloses a kind of drainage tube of enrich tumor exfoliative cyte, comprise drainage tube main body, one end that described drainage tube main body is positioned at splanchnocoel is provided with flatbed bending part, and the step place that described flatbed bending part is relative with seroperitoneum flow direction is provided with the groove for depositing exfoliated tumor cells.The position that this utility model is positioned at body at drainage tube is set to bending shape structure, and groove is set at the step place of corresponding seroperitoneum flow direction, add tumor cell and stop enriching machine meeting, can ensure tumor cell by time can be adsorbed in pipe by sedimentation, improve tumor cell recall rate, effectively avoid failing to pinpoint a disease in diagnosis of tumprigenicity ascites pleural fluid, provide Reliable guarantee for patient treats in advance.
Description
Technical field
This utility model relates to technical field of medical instruments, particularly a kind of drainage tube for drain 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 the ascites pleural fluid censorship of 5 ~ 10ml is outwards extracted clinically often at random with drainage tube; But due at initial stage of cancer, cancer cell number is less, therefore there will be and fails 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 one and are applied in clinical medicine, outwards extract the drainage tube of ascites pleural fluid, can carry out sedimentation, to improve the recall rate of tumor cell to the tumor cell in ascites pleural fluid from splanchnocoel.
For solving the problems of the technologies described above, technical solution adopted in the utility model is as follows.
The drainage tube of enrich tumor exfoliative cyte, comprise drainage tube main body, one end that described drainage tube main body is positioned at splanchnocoel is provided with flatbed bending part, and the step place that described flatbed bending part is relative with seroperitoneum flow direction is provided with the groove for depositing exfoliated tumor cells.
The drainage tube of above-mentioned enrich tumor exfoliative cyte, the step that described flatbed bending part is relative with seroperitoneum flow direction is provided with for adherent tumor exfoliative cyte and covers the adsorption layer of groove.
The drainage tube of above-mentioned enrich tumor exfoliative cyte, the inwall of described drainage tube main body 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.
The position that this utility model is positioned at body at drainage tube is set to bending shape structure, and groove is set at the step place of corresponding seroperitoneum flow direction, add tumor cell and stop enriching machine meeting, can ensure tumor cell by time can be adsorbed in pipe by sedimentation, improve tumor cell recall rate, effectively avoid failing to pinpoint a disease in diagnosis of tumprigenicity ascites pleural fluid, provide Reliable guarantee for patient treats in advance.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Wherein: 1. drainage tube main body, 2. flatbed bending part, 3. groove.
In figure, the direction of arrow is seroperitoneum flow direction.
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.
The drainage tube of enrich tumor exfoliative cyte, its structure as shown in Figure 1, comprises drainage tube main body 1, and one end that drainage tube main body 1 is positioned at splanchnocoel is provided with flatbed bending part 2, flatbed bending part can arrange multilamellar, arranges three layers of flatbed bending part 2 in the present embodiment altogether.
The step place that flatbed bending part 2 is relative with seroperitoneum flow direction is provided with groove 3, and for depositing exfoliated tumor cells, groove can be set up in parallel multiple, and in the present embodiment, every layer of step place all arranges two grooves 3.
The step that flatbed bending part 2 is relative with seroperitoneum flow direction is provided with adsorption layer 3, and adsorption layer 3 is for adherent tumor exfoliative cyte.Adsorption layer in this utility model is be body fluid and curing agent mixture layer before the PDMS of 3:1 containing volume ratio.
The inwall of drainage tube main body 1 is wrapped up in epithelial cell specific antibody film.
When this utility model makes, be first positioned at one end platform for making type bending part of splanchnocoel in drainage tube main body; Secondly, the step place relative with seroperitoneum flow direction at flatbed bending part arranges groove; Then, body fluid and curing agent mixture before to smear volume ratio on the step that flatbed bending part is relative with seroperitoneum flow direction be the PDMS of 3:1, then drainage tube is put into 65 degrees Celsius of oven for solidifying three hours, form adsorption layer; Finally, then be that the epithelial cell specific antibody of 800-1500ug/ml pours in drainage tube by concentration, and give 4 degrees Celsius of environment and preserve and can form epithelial cell specific antibody film on drainage tube inwall.
When this utility model uses, directly the drainage tube one end with bending part is inserted in splanchnocoel, in the time period that drainage tube is built-in in splanchnocoel, in the process that exfoliated tumor cells flow at hydrothorax, be deposited to groove interior and be adsorbed on adsorption layer.After drainage tube takes out, when detecting tumor cell to Pathology Deparment, by the groove of elution drainage tube bending part, the hydrops containing more exfoliated tumor cells can be collected, 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.
