Problems solved by technology
[0003] At present, the general tools used for bone marrow fluid collection are generally based on bone puncture needles. However, the existing bone puncture needles have poor protection, are inconvenient to install and disassemble, and are inconvenient to carry. It will be very difficult for the personnel to use it, which increases the labor intensity of the medical staff and is inconvenient to use. Therefore, we propose a hematology bone marrow puncture needle to solve the above problems
