[0093] In the above embodiments, it should be noted that during the puncture training process, the needle is inserted along the puncture point, puncture direction, and puncture depth determined by ultrasound. If the resistance at the needle tip suddenly disappears during the puncture, it indicates that the puncture needle has passed through the pericardial wall layer. If the heartbeat is felt at the needle tip at the same time, the needle should be withdrawn slightly to avoid scratching the heart and blood vessels, while fixing the needle body. If no fluid flows out after reaching the measured depth, the needle can be withdrawn to the subcutaneous layer, the puncture direction slightly changed, and then tried again.
