通过体外血肿模型及自制的血肿抽吸装置进行血肿抽吸，测定27℃下孵育4、2、12、16,20、24h的血块抽吸所需的最大负压值，探讨了负压随时间变化的规律。结果表明，时间可影响血肿抽吸时的负压（P＜0．01），4h抽吸血肿时负压最大，与其它时间比较有极显著差异（P＜O．01）；8h抽吸血肿时负压降低，与12h至24h抽吸负压比较有极显著差异（p＜0．01）；12h至24b期间任意两时间相比较抽吸负压无显著差异（P＞0．05）。在12h至24h期间抽吸负压较低，容易成功。
Hematoma aspiration was performed by in vitro hematoma model and self-made hematoma aspiration device, and the maximum negative pressure required for blood clotting at 4, 2, 12, 16, 20 and 24 hours at 27 ℃ was measured. The law of change. The results showed that time could affect the negative pressure during hematoma aspiration (P <0.01), the maximum negative pressure at 4h after hematoma aspiration (P <0.01), the 8h aspiration hematoma (P <0.01). There was no significant difference in aspiration negative pressure between any two time points from 12h to 24b (P> 0.05). During the 12h to 24h suction negative pressure is low, easy to succeed.
