Detailed introduction

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) Electric Von Frey Electromechanical threshold pain threshold tactile threshold measurement instrument Threshold and pain threshold, scientific design, complete configuration, simple operation, please call for more details)

 

Model: 2390 (accuracy 0.01g), 2091 (accuracy 0.1g), 2092 (including Supertips), 2397 (nuclear magnetic compatible model) ...


触觉阈 疼痛阈 测量仪 机械痛阈测量仪 Von Frey 系统,简单易用。 Electronic tactile threshold pain threshold measuring instrument Mechanical pain threshold measuring instrument Von Frey system, easy to use. Von Frey To replace the traditional Von Frey   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。 Hairs ciliary mechanical stimulation needles ( Von Frey Hairs ) . Not only can Von Frey test measure mechanical pain threshold or tactile threshold measurement, but also pain threshold. It enables researchers to automatically record mechanical pain threshold and tactile threshold measurements. Simple and accurate operation and compact equipment.

 

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.

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 You can preset and select the maximum limit, which can be accurate to 1g . When the preset limit is reached, the warning light will notify the user .

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 Simple experiment: Select the appropriate original on the probe and insert it into the test object. According to the reaction of the test object, the instrument can quickly display the result and store it.

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。 Ø The built-in sensor as the core original is fixed on the component and connected to the electronic system in order to record data. All electronic painmeters have been calibrated before leaving the factory, no need to purchase any calibration equipment.


The main specifications of Von Frey electronic pain meter:

 

本仪器提供的探针有90g、800 g和1000g三种规格。 1. The probes provided by this instrument have three specifications: 90g, 800g and 1000g. The type of probe depends on the subject.

2390 系列支持研究人员在单体内插入三个探针。 2. The 2390 series allows researchers to insert three probes into the cell. Support multiple users to do multiple research with a single unit.

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。 3. Hard head electronic pain meter is used to evaluate mechanical pain (threshold), and "Supertips ™" ( soft head ) is used to detect all sensory threshold tests. —— 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。 The design of the test wire is unique -the diameter of the end of each soft head is 0.8mm , which can effectively eliminate misreading. (The reason for the misreading is caused by the uneven thickness of the test wire).
