The application of disposable connecting tube in bone marrow puncture

Bone marrow puncture is one of the common operations in hematology department, in which a puncture needle is inserted into the bone marrow cavity to extract a small amount of bone marrow for testing. In bone marrow aspiration, a 20mL syringe is often used to aspirate bone marrow, but the 20mL syringe is often not closely connected with the original disposable bone marrow puncture needle connector, which often causes difficulties in marrow aspiration or the leakage of puncture fluid in the process of aspiration and contaminates the bed sheet.
