Clinical Application Value Of 45mm Vascular Access Needle In Bone Marrow Transplantation
Jul 31, 2026
Professional manufacturers position the 45mm 15G Vascular Access Needle not only as an emergency infusion device but also as a key auxiliary instrument for clinical bone marrow sampling and transplantation treatment, with irreplaceable application value in the field of hematology medicine. Human large hollow bones are filled with bone marrow tissue rich in hematopoietic stem cells, which can differentiate into red blood cells, white blood cells and platelets, and support the daily renewal of hundreds of billions of blood cells in the human body. The 45mm long needle body design can accurately penetrate the thick subcutaneous fat and cortical bone of obese and large patients, smoothly reach the bone marrow cavity, and complete safe bone marrow sampling and vascular access establishment, providing reliable technical support for bone marrow transplant diagnosis and treatment.
In the bone marrow donor sampling link, the 45mm Vascular Access Needle is one of the core tools for direct iliac crest bone marrow extraction. Compared with blood component separation technology, direct bone marrow puncture and sampling has the advantages of high stem cell activity and simple operation, which is suitable for clinical precise sampling of donor hematopoietic stem cells. For large and obese donors with thick subcutaneous fat, conventional short needles cannot reach the effective bone marrow cavity, resulting in insufficient sampling volume and failed operation. The 45mm extended needle body of manufacturer-standard products perfectly adapts to this scenario, ensuring accurate puncture depth, complete sampling process, and effectively guaranteeing the activity and quantity of collected hematopoietic stem cells, laying a solid foundation for subsequent transplant treatment.
In recipient treatment and cell transfusion links, the 45mm Vascular Access Needle assists in establishing stable central vascular access. Before bone marrow transplantation, recipients need high-dose chemotherapy and radiotherapy to clear cancer cells and original bone marrow hematopoietic function, which will lead to peripheral vascular fragility and collapse. The high-stability 45mm long needle can quickly establish a durable vascular channel, realizing safe and stable transfusion of donor stem cells. After transfusion, stem cells rely on chemokine homing mechanism to migrate to the bone marrow cavity, proliferate rapidly and rebuild the patient's hematopoietic and immune system. The stable channel performance of manufacturer-produced needles ensures the continuous and effective progress of cell homing and proliferation.
In addition, the product plays an important role in monitoring and reducing transplant risks. Bone marrow transplantation may cause graft-versus-host disease (GVHD), where donor immune cells attack the recipient's original organs. The precise and low-trauma puncture performance of high-quality 45mm vascular access needles reduces secondary tissue damage and postoperative infection risks for patients. Combined with standardized clinical operation, it can effectively cooperate with immunosuppressive drug treatment and immune cell intervention, reduce the incidence of transplant complications, and improve the overall success rate and safety of bone marrow transplantation, making it a necessary supporting device for professional hematology transplant institutions.
