Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, in particular to a targeted treatment device for multiple myeloma. Background Art

[0002] Multiple myeloma is a malignant plasma cell disease whose tumor cells originate from plasma cells in the bone marrow. Plasma cells are cells that have developed from B lymphocytes to the final functional stage. Therefore, multiple myeloma can be classified as a B-cell lymphoma. Targeted therapy is a treatment method that targets a well-defined oncogenic site at the cellular and molecular level (this site can be a protein molecule inside the tumor cell or a gene fragment). Corresponding therapeutic drugs can be designed. When the drugs enter the body, they will specifically select the oncogenic site to combine and act, causing the specific death of tumor cells without affecting the normal tissue cells around the tumor. Therefore, molecular targeted therapy is also called a "biological missile". Targeted treatment methods mostly use injections. Currently available targeted treatment devices for multiple myeloma, syringes, do not have a certain protective structure. After use, the syringe needle is directly exposed to the outside world, posing a certain safety hazard. Therefore, a targeted treatment device for multiple myeloma is proposed to solve the above-mentioned problems. Summary of the Invention
