数据记忆动物游泳测试仪的研制

Development of a Data-Memory Based Instrument to Test Swimming Conditions of Animals

目的研制一种用于检测动物负载游泳状况及过程的仪器,用于动物疲劳游泳试验。方法采用不同直径的可调换加载钢球、恒温水池、接近传感器信号转换、51系列单片微机控制和记忆信号。结果研制出一台可同时做六路平行实验的动物游泳测试仪,自动记忆动物在加载的情况下抗疲劳游泳的全过程。结论经36例小鼠实验证明,效果良好,该仪器为动物负载游泳实验提供了一种全新的测试方法。

Objective To develop an instrument for testing the swimming condition of load-carrying animals. Methods Steel balls in different diameter, which were interchangeable, were used as loads of different weights. Experimental animals were allowed to swim with different loads in a water pool at constant temperature. Proximity sensors were used for signal conversion. A 51-Series microcontroller was used to control and record the experiment signals. Results A data-memory based instrument to test swimming conditions of animals carrying different load was developed. This instrument could be used to perform six parallel tests. It could automatically record swimming conditions of load-carrying animals. 36 mice were successfully tested with this instrument, demonstrating excellent results. Conclusion A data-memory based instrument to test swimming conditions of animals has been successfully developed, which offers an novel tool in studies to test swimming conditions of load-carrying animals.
