[0002] In clinical work, it is very common to collect patient body fluid specimen by using a syringe. However, there are many problems in the process of transferring the body fluid from the syringe to a vacuum specimen tube. For example, in bone marrow puncture + biopsy examination, step one: after fixing the bone marrow puncture needle, connect the syringe (without needle tube) to extract bone marrow fluid;

[0003] Step two: the assistant holds the vacuum specimen tube, and the operator connects the needle tube to the syringe and injects the bone marrow fluid into the vacuum specimen tube;

[0004] Step three: the operator removes the bone marrow puncture needle and performs bone marrow biopsy with a biopsy needle.

[0005] In step two: the operator may prick the assistant; the body fluid may drip from the needle and contaminate the outside of the specimen tube and the environment. The vacuum specimen tube has negative pressure, which can actively attract a certain amount of specimen when the needle is inserted. However, when more specimen is pushed in, the body fluid may splash and contaminate the specimen tube, the operator and the environment when the needle is pulled out due to the pressure.

[0006] In step two, the sterile gloves of the operator may touch the specimen tube by mistake, causing contamination, and the gloves need to be replaced to continue step three, increasing additional expenses.
