Binding-fixation is the most commonly used method for acupuncture research in rats

but its resulted stronger stress response may affect the experimental outcomes. Hence

we developed a practical fixing device using the abandoned meshy cage covers

bolts

hooks

and loop fasteners. It includes two straps

two ropes

a small jacket with a self-locking Velcro strap and a meshy cage cover with a piece of fixed Velcro which may be placed on a rectangular storage box. Rats can be fixed in a recumbent position or a prone position. Outcomes showed that it is not only convenient and cheaper but also has a higher successful rate of fixation and a longer fixation time for completing an experiment.
