37450 - 動(dòng)態(tài)足底觸覺儀
動(dòng)態(tài)足底觸覺儀是用以自動(dòng)評(píng)估嚙齒類動(dòng)物跖面的“觸覺感應(yīng)”性能。它與電子觸覺測(cè)量(Electronic Von Frey )和足底觸覺測(cè)量(Plantar Von Frey )類似多種方式,不同之處在于它能記錄持續(xù)時(shí)間和爪縮回時(shí)的作用力。
可移動(dòng)的觸覺刺激裝置放于實(shí)驗(yàn)動(dòng)物足底實力增強,可根據(jù)實(shí)驗(yàn)人員需要設(shè)定力的大小和力增大的速度等體系流動性。
觸覺測(cè)量套件( Von Frey )以每次增加直徑0.05mm的細(xì)絲增加施力,直到受試動(dòng)物的爪抽搐帶來全新智能。
動(dòng)態(tài)足底觸覺計(jì)的新模式為:
一臺(tái)可移動(dòng)的觸覺刺激裝置實現了超越,配備刺激絲和可調(diào)整角度的鏡子;
實(shí)為一微電子處理單位去完善,提供數(shù)字顯示橋梁作用、內(nèi)部數(shù)據(jù)存儲(chǔ)、可用閃存導(dǎo)出數(shù)據(jù)求索、可外接打印機(jī)讓人糾結;
寬敞的實(shí)驗(yàn)操作平臺(tái);
模塊化的動(dòng)物籠穩定發展,可自由組合3-12個(gè)隔間基石之一。
