详细介绍

Electric Von Frey电子机械疼痛阈触觉阈测量仪Von Frey test(Von Frey Hairs, Von Frey纤维丝 纤毛机械刺激针,电子测痛仪,Von Frey Hairs,触觉测量套件)(使用Von Frey Hairs测试触觉阈值和疼痛阈值,设计科学,配置齐全,操作简单,更多详情敬请来电咨询)

 

电子触觉阈疼痛阈测量仪机械痛阈测量仪Von Frey系统,简单易用。用来替代传统的Von Frey Hairs纤毛机械刺激针Von Frey Hairs.不仅可以Von Frey test测试机械痛阈或触觉阈测量,还可以测试疼痛阈值。这个系统是10年前第一个进入市场的产品,它使研究者可以自动记录机械痛阈和触觉阈测量。操作简单,精确,设备紧凑。

 

The original Electronic von Frey is used to assess mechanical allodynia with rigid tips (threshold) and the “Supertips™” (flexible von Frey hairs) are used for sensory test on all test subjects.

 

Our system is the first system introduced to the market over 10 years ago which finally allows researchers the ability to test and automatically record pain threshold values in a clean, accurate easy to use compact system.

 

Testing is simple, choose one of the supplied tips place on probe tip; apply pressure probe to test subject, upon reaction the unit will display and store your reading in grams, an easy, quick test system for all pain studies.

电子Von Frey测痛仪特点:

 

Ø 适用MRI探针

Ø 单体内可插入三个探针

Ø LCD 显示屏 (Floating or last max. & minimum) 

Ø 硬枪头能达 800 Gr. 

Ø “Supertips™” 15 到 65 Gr. 

Ø 适用1K探针

Ø 电子微处理器 0.1 Gr 插入式探针

Ø 防潮

Ø 隔温 

Ø 可选的模拟输出线

Ø 吸头可根据情况定制

Ø 具有测量、存储和显示功能,免除了手算的繁琐。

Ø 可以预设和选择最大限额,能精确到1g当到预设的限额时,警示灯会通知使用人员

Ø 实验简便:选择合适的原件放在探针上,插进实验对象,根据实验对象的反应,仪器就能快速的显示出结果并储存。

Ø 作为核心原件的内置传感器固定在元件上,并和电子系统相连,以便记录数据。所有的电子测痛仪已在出厂前校准完毕,不再需要购买任何的校准设备。

 

  Von Frey电子测痛仪的主要规格配置:

 

1、本仪器提供的探针有90g、800 g和1000g三种规格。探针的类型视实验对象而定。

2、2390系列支持研究人员在单体内插入三个探针。支持多个用户用一个单体做多个研究。

3、硬头电子测痛仪用来评估机械痛(阈值),“Supertips™”(软头)用来检测所有的感官阈测试。测试丝设计独特——每个软头的末端直径为0.8mm 可以有效的消除误读的情况发生。(误读的原因是由测试丝的薄厚不均造成的)。
