詳細介紹

Electric Von Frey電子機械疼痛閾觸覺閾測量儀Von Frey test(Von Frey Hairs, Von Frey纖維絲,纖毛機械刺激針,電子測痛儀,Von Frey Hairs,觸覺測量套件)(使用Von Frey Hairs測試觸覺閾值和疼痛閾值,設計科學,配置齊全,操作簡單,更多詳情敬請來電咨詢)

 

型號:2390(精度0.01g)、2091(精度0.1g)、2092(含Supertips軟絲)、2397(核磁兼容型號)···


電子觸覺閾疼痛閾測量儀機械痛閾測量儀Von Frey系統,簡單易用。用來替代傳統的Von Frey Hairs纖毛機械刺激針Von Frey Hairs.不僅可以Von Frey test測試機械痛閾或觸覺閾測量,還可以測試疼痛閾值。它使研究者可以自動記錄機械痛閾和觸覺閾測量。操作簡單,精確,設備緊湊。

 

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.

? 可以預設和選擇最大限額,能精確到1g,當到預設的限額時,警示燈會通知使用人員。

? 實驗簡便:選擇合適的原件放在探針上,插進實驗對象,根據實驗對象的反應,儀器就能快速的顯示出結果并儲存。

? 作為核心原件的內置傳感器固定在元件上,并和電子系統相連,以便記錄數據。所有的電子測痛儀已在出廠前校準完畢,不再需要購買任何的校準設備。


Von Frey電子測痛儀的主要規格配置:

 

1、本儀器提供的探針有90g、800 g和1000g三種規格。探針的類型視實驗對象而定。

2、2390系列支持研究人員在單體內插入三個探針。支持多個用戶用一個單體做多個研究。

3、硬頭電子測痛儀用來評估機械痛(閾值),“Supertips?”(軟頭)用來檢測所有的感官閾測試。測試絲設計獨特——每個軟頭的末端直徑為0.8mm ,可以有效的消除誤讀的情況發生。(誤讀的原因是由測試絲的薄厚不均造成的)。
