37450 - 動態(tài)足底觸覺儀
動態(tài)足底觸覺儀是用以自動評估嚙齒類動物跖面的“觸覺感應(yīng)”。它與電子觸覺測量（Electronic Von Frey ）和足底觸覺測量（Plantar Von Frey ）類似，不同之處在于它能記錄持續(xù)時間和爪縮回時的作用力。
可移動的觸覺刺激裝置放于實驗動物足底，可根據(jù)實驗人員需要設(shè)定力的大小和力增大的速度等。
觸覺測量套件（ Von Frey ）以每次增加直徑0.05mm的細絲增加施力，直到受試動物的爪抽搐。
動態(tài)足底觸覺計的新模式為：
一臺可移動的觸覺刺激裝置，配備刺激絲和可調(diào)整角度的鏡子；
實為一微電子處理單位，提供數(shù)字顯示、內(nèi)部數(shù)據(jù)存儲、可用閃存導(dǎo)出數(shù)據(jù)、可外接打印機；
寬敞的實驗操作平臺；
模塊化的動物籠，可自由組合3-12個隔間。
