Specimen sampling device for blood tumorTechnical Field
The invention relates to the technical field of medical equipment, in particular to a specimen sampling device for blood tumor.
Background
Tumors are a genetic disorder, but are not inherited. It is a new organism formed by that the cell gene is changed under the action of carcinogenic factor, and loses the normal regulation and control of its growth, so that it can result in the abnormal proliferation of monoclonality. This neoplasm often forms localized lumps and is thus named. According to the biological characteristics of tumors and the difference of harmfulness to organisms, tumors can be divided into two major types, namely benign tumors and malignant tumors. The former has slow growth, clear boundary with surrounding tissues, no transfer and little harm to human health. The latter grows rapidly, can be transferred to other parts of the body, can also produce harmful substances, damage normal organ structures, cause organism dysfunction and threaten life. There is a fundamental distinction between neoplastic and non-neoplastic hyperplasia: the non-tumor hyperplasia is required for the living of the organism, the hyperplastic tissue can be differentiated and matured, and the structure and the function of the original normal tissue can be recovered, and the hyperplasia can not be continued to a certain extent. The normal cells are transformed into tumor cells, have abnormal shapes, metabolism and functions, lose the capacity of differentiation and maturation to different degrees, grow vigorously and have relative autonomy, and can grow continuously even if no tumorigenic factors exist later.
Traditional tumour sample sampling device, when using, can't accomplish to accomplish effectual observation control to syringe needle depth of insertion to traditional device is when using, can't accomplish the effective clearance disinfection to syringe needle puncture position, can't accomplish still that the tumour liquid of flowing out to puncture position accomplishes effectual absorption, this probably can make tumour liquid be infected with healthy human body, brings the threat to healthy personnel, for this reason we provide a blood tumour and solve above-mentioned problem with sample sampling device.
