Description

TECHNICAL FIELD

[0001] The utility model relates to medical instrument technical field especially relates to a bone marrow blood cell filters collection device. BACKGROUND

[0002] Hematopoietic stem cell transplantation is the most effective method for treating various malignant hematological diseases, some solid tumors and autoimmune diseases. The source of hematopoietic stem cells mainly includes bone marrow, peripheral blood stem cells and umbilical cord blood. The bone marrow collected during bone marrow transplantation is actually a mixture of bone marrow and blood. After the bone marrow blood cells are extracted from the donor's bone marrow cavity, some impurities such as skin or bone debris, blood clots, fat particle aggregates, etc. will be mixed in them, which need to be filtered before being transfused to the recipient.

[0003] Now the syringe needle filtering method is mostly used in clinical operation, and the size of the needle aperture can allow the bone marrow blood cells to pass through. However, the impurities are easy to coagulate at the needle, causing the needle to be blocked. The tube diameter of the syringe nipple is narrow and has no anti-falling structure, which can easily cause the bone marrow blood to overflow after being connected with the needle, resulting in waste of bone marrow blood. In addition, the needle is inserted into the storage bag of blood products to connect the thin tube, and the resistance is large when the syringe is injected, which is not conducive to the operation of the operator.
