本发明的海底小生物诱捕与保压保温装置的使用方法，包括如下步骤：
1)在海底小生物诱捕与保压保温装置下水之前，根据海底小生物所处的水深通过截止阀12向保压筒8的B腔内的活塞18下部容腔充气0.3倍水深压力的氮气，此时保压筒8的B腔内的活塞18将处于保压筒8的B腔的顶部；并通过弧形收集口103向保压筒8内注满蒸馏水，然后用密封盖1301将密封杆104的导孔105密封；卸下橡胶瓶9，并向橡胶瓶9内注满蒸馏水，然后将其拧接回原位。在海底小生物诱捕与保压保温装置从水面下降至海底小生物诱捕作业点过程中，橡胶瓶9内的蒸馏水在外界海水压力作用下经单向阀10缓慢进入保压筒8的A腔，同时迫使保压筒8的B腔内的活塞18向下运动，直至保压筒8的A腔和保压筒8的B腔内的活塞18上部容腔的蒸馏水压力以及保压筒8的B腔内的活塞18下部容腔内的氮气压力均与外部海水对应水深压力相等为止。在海底小生物诱捕与保压保温装置完成水下作业返回水面过程中，保压筒8的B腔内的活塞18下部容腔内的氮气压力(此时保压筒8的B腔内的活塞18下部容腔相当于1个补偿器)将实时补偿保压筒8因内外压差变化而引起体积膨胀。
2)利用水下机器人的一只机械手抓取所述的海底小生物诱捕与保压保温装置的手柄15，然后将海底小生物诱捕与保压保温装置移动至海底小生物诱捕目标底质表面，并利用支撑杆21将海底小生物诱捕与保压保温装置稳定支撑在海底表面。
3)利用水下机器人的另一只机械手拉拔密封盖开启机构13的拉环1304，打开密封盖1301，卡绳机构14的一对卡绳杆1404将卡住钢丝绳1303上的绳卡1305，防止密封盖1301下落。
4)深海底小生物经收集与密封机构1的过滤孔102、导孔105进入保压筒8内，体积较大的生物将被隔离在过滤盘101外，待足够多的深海底小生物进入保压筒8内后，通过机械手按压扳机3，解除扳机3对密封杆104的限位，密封杆104在锁紧弹簧2作用下锁紧并密封保压筒上端盖5。
5)利用机械手将海底小生物诱捕与保压保温装置收回。
