Mechanical Analgesia Tester for Experiment Animal

Objective To develop an electrical mechanical analgesia tester to measure pain threshold measurement in neuro-physiological research.Method Based on analysis of flaws of conventional mechanical analgesia tester,a high-accuracy force sensor was selected and hardware circuit for signal acquisition and processing was developed.Combined with software programmed in VC,pain threshold measurement and data storage and display were realized.Results An electrical mechanical analgesia tester was developed and it could measure pain threshold conveniently and quickly.Conclusion Experiments results show that the analgesia tester has high accuracy,and is good in stability and accuracy.The measure results are invulnerable to environmental factors as temperature and moistness.The newly developed analgesia tester overcomes the flaw of conventional analgesia tester and can provide technical support for researching and analyzing etiopathogenesis of neuropathic pain,also for evaluating effectiveness of pain analgesics.
