Combined type has the marrow filter of multi-filtering function
Technical field
Marrow filter the utility model relates to the field of medical instrument technology more particularly to combined type with multi-filtering function
Device.
Background technique
Hematopoietic stem cell transplantation is the current effective ways for curing malignant hematologic disease, and transplanting mode includes that peripheral blood hematopoietic is dry
Cell transplantation, bone-marrow transplantation and mixed transplantation;Bone-marrow transplantation and mixed transplantation need to acquire donor bone marrow's candidate stem cell.Generally
Using under caudal anaesthesia after donor ilium or anterior superior spine carry out bone marrow collection art, using empty needle acquire marrow blood, collection capacity
For 10-15ml/kg (receptor's weight), after acquisition due in the marrow blood of acquisition in addition to marrow hemopoietic stem cells, leucocyte, red thin
Outside the blood cell compositions such as born of the same parents, blood platelet, there are also fat, marrow clast etc., it is transfused to the filtering for needing to carry out marrow blood before receptor
Fatty, marrow clast is removed as far as possible in order to avoid causing receptor's fat and foreign matter embolism.
According to above-mentioned, the method for current routine clinical use has to be filtered or syringe needle by the strainer of 200-300um
Filtration method (No. 16 and No. 9 syringe needles respectively filter once), which wants although can reach certain filtering
It asks, but there are the following problems:, because filter efficiency is limited, it is residual to have significant quantities of fat cell after 1, strainer filtering and syringe needle filtering
It stays;2, Full-open environment be easy to cause marrow hemopoietic stem cells to pollute;3, syringe needle filter pressure is excessive will cause candidate stem cell
It destroys, the breaking-out of receptor's haemolysis or even threat to life is easily caused after infusion, in view of disadvantages described above, it is really necessary to design combined type
Marrow filter with multi-filtering function.
