动态足底触觉仪

  • 产品概述
  • 产品参数
  • 产品特性
  • 产品应用

    动态足底触觉仪是用以自动评估啮齿类动物跖面的“触觉感应”。它与电子触觉测量(Electronic Von Frey )和足底触觉测量(Plantar Von Frey )类似,不同之处在于它能记录持续时间和爪缩回时的作用力。 可移动的触觉刺激装置放于实验动物足底,可根据实验人员需要设定力的大小和力增大的速度等.

    开始:

    软键

    可设力范围:

    0 -50.0 g, 分辨率为0.5 g

    可设力增加率:

    1 - 50 s, 分辨率为1s

    着力丝移动范围;

    12 mm

    实验时间:

    液晶屏显示,分辨率为0.1s

    接电脑:

    DELTA 9-pin 连接线

    电源:

    规格:

    动物罩子:

    85-264 VAC  -   50-60Hz   - 20 W max

    85 x 40 x 40 cm

    3个,每个20x20x14(h) cm

    净重:

    12.50 Kg.

    毛重:

    包装规格:

    约21.50 Kg

    98x49x47cm



    特征

    优点

    仪器自动施力

    施力速度、方向等保持一致性

    操作人员只需按动开关

    相比用Von Frey测试,本实验时间短,且操作人员不会感到沉闷

    力的大小和增加量可预置

    更多参数符合实验需要

    Chronic Constriction of the Sciatic Nerve and Pain Hypersensitivity Testing in Rats

    Due to the simplicity of surgery and the robust behavioural outcome, chronic constriction of the sciatic nerve is one of the pre-eminent animal models of neuropathic pain. Within 24 hrs following surgery, pain hypersensitivity is established and can be quantitatively measured using a von Frey aesthesiometer (mechanical test) and plantar analgesia meter (thermal test).
