Description

A kind of sample sampling device for blood tumor

technical field

The invention relates to the technical field of medical equipment, in particular to a sample sampling device for blood tumors.

Background technique

Cancer is a genetic disease, but not hereditary. It refers to a new organism formed by the abnormal proliferation of monoclonal cells due to the change of genes under the action of carcinogenic factors and the loss of normal regulation of their growth. The new organisms often form localized lumps, hence the name. According to the biological characteristics of tumors and their harm to the body, tumors can be divided into two categories: benign tumors and malignant tumors. The former grows slowly, has a clear boundary with the surrounding tissues, does not transfer, and is not harmful to human health. The latter grow rapidly, can be transferred to other parts of the body, and also produce harmful substances, destroy the normal organ structure, make the body dysfunctional, and threaten life. There is an essential difference between neoplastic hyperplasia and non-neoplastic hyperplasia: non-neoplastic hyperplasia is needed for the survival of the body, and the proliferated tissue can differentiate and mature, and can restore the structure and function of the original normal tissue, and this hyperplasia will not be able to reach a certain limit. Continue. Normal cells transformed into tumor cells have abnormal morphology, metabolism, and function, lose the ability to differentiate and mature to varying degrees, grow vigorously, and are relatively autonomous.

The traditional tumor sample sampling device cannot effectively observe and control the insertion depth of the needle during use, and the traditional device cannot effectively clean and sterilize the needle puncture site when it is in use. To effectively absorb the tumor fluid flowing out of the puncture site, it is very likely that the tumor fluid will be contaminated with healthy human bodies and pose a threat to healthy personnel. Therefore, we propose a blood tumor sample sampling device to solve the above problems.
