What is the intraosseous access needle?

Many factors are involved in the regulation of hematopoietic function of bone marrow: the reduction of oxygen in the blood stimulates the formation of red blood cells; Similarly, living at altitude increases red blood cells; Blood loss enhances the mitosis of cells in the bone marrow. Protein in food promotes the formation of red blood cells; Vitamin B2 must be present during the normal process of red blood cell formation.

Bone marrow cells are the general term for the various cells in the bone marrow (mainly red bone marrow). Bone marrow is the main hematopoietic organ, producing red blood cells, granulocytes, monocytes, lymphocytes and platelets, so bone marrow cells include a variety of blood cell lines at different stages of development, the composition is complex. Such as granulocytes, about 40% ~ 60%, including promyelocytic granulocytes, promyelocytic granulocytes, middle myelocytic granulocytes, late myelocytic granulocytes, rod granulocytes and lobecuclear granulocytes; Lymphoid cell lines account for about 20%.
