7. The method for using a bone marrow biopsy sampling reminding device according to claim 4, wherein when bone marrow puncture is performed, a switch is closed, a biopsy needle (5) is inserted into a puncture needle (4) to puncture, at the moment, the needle tip of a solid needle core of the biopsy needle exceeds the front end of a hollow needle of the puncture needle, after the solid needle core of the biopsy needle enters a bone marrow cavity, the biopsy needle (5) is taken out, at the moment, bone marrow liquid is attached to the front ends of the biopsy needle (5) and the puncture needle (4), but a circuit path is not formed due to the fact that the switch is in a closed state, and an alarm device does not alarm; then connecting the syringe needle cylinder with a puncture needle (4) to suck bone marrow fluid; when a bone marrow biopsy is performed, a switch is turned on, the puncture needle (4) is connected with the biopsy needle (5) through the connecting column (8), a cavity of 2-4 cm is formed between the hollow needle of the puncture needle and the solid needle core of the biopsy needle, then the hollow needle continuously punctures and collects bone marrow tissues, and when the bone marrow tissues containing a small amount of bone marrow liquid enter the puncture needle (4) until contacting with the needle tip of the biopsy needle (5) which is not coated with an insulating coating, a circuit path is formed, so that an alarm device sends out a prompt to remind a doctor of taking enough bone marrow tissues without continuously puncturing.
8. The method for using the bone marrow biopsy sampling reminding device according to claim 7, wherein when bone marrow puncture is performed, a switch is closed, a biopsy needle (5) is sleeved into a puncture needle (4) for puncture, and the needle tip of a solid needle core of the biopsy needle exceeds the front end of a hollow needle of the puncture needle; after entering the bone marrow cavity, taking out the biopsy needle (5), wherein the front ends of the biopsy needle (5) and the puncture needle (4) are attached with bone marrow liquid, but a circuit path is not formed because the switch is in a closed state, the buzzer alarm (3) does not alarm, and the indicator lamp is not on; then connecting the syringe needle cylinder with a puncture needle (4) to suck bone marrow fluid; when bone marrow biopsy is performed, a switch is turned on, the puncture needle (4) is connected with the biopsy needle (5) through a connecting column (8), and a cavity of 2-4 cm is formed between the puncture needle hollow needle and the biopsy needle solid needle core; and then the hollow needle continuously punctures and collects bone marrow tissues, when the bone marrow tissues containing a small amount of bone marrow liquid enter the puncture needle (4) until the bone marrow tissues are contacted with the needle tip of the biopsy needle (5) which is not coated with the insulating coating, a circuit path is formed, so that the indicator light and the buzzer alarm (3) give out prompts to remind a doctor that the sufficient amount of bone marrow tissues are taken, and the continuous puncturing is not needed.
9. The method according to claim 7 or 8, wherein the height of the receiving post (8) is 3cm, so that a cavity of 3cm is formed between the hollow needle of the puncture needle and the solid needle core of the biopsy needle.
10. A bone marrow biopsy sampling prompt device according to any one of claims 1 to 6 for quantitative sampling of bone marrow biopsies.
