(四合一)痛覺測痛系統

時間:2016-09-14來源:本站作者:玉研儀器

詳細介紹

四合一痛覺測試系統包含電子von Frey測痛儀、鼠爪壓力測量儀、鼠爪腫脹測量儀、抓力測量儀四套電子痛覺測量儀,用四種方法完成對大鼠小鼠等動物的痛覺測量,歡迎來電咨詢。


  • Electronic von Frey Anesthesiometer 電子von Frey測痛儀

  • Randall Selitto test Paw Pressure Test Meter 鼠爪壓力測量儀

  • Plethysmometer, Paw Volume Meter or Paw Edema Meter鼠爪腫脹測量儀

  • Grip Strength Meter Mice and Rats 抓力測量儀


型號:2390型+2500型+520MR型+2200型


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,設計緊湊。


電子Von Frey測痛儀的主要特點:

適用MRI探針

單體內可插入三個探針

LCD 顯示屏 (Floating or last max. & minimum) 

硬槍頭能達 800 Gr. 

“Supertips?” 15 65Gr. 

適用1K探針

電子微處理器0.1Gr插入式探針

可選的模擬輸出線

吸頭可根據情況定制

具有測量、存儲和顯示功能,免除了手算的繁瑣。

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。


鼠爪壓力測痛儀 Randall&Selitto測試,通過逐步提高作用于動物爪子上的機械壓力,逼近動物的疼痛閾限,測量并記錄動物產生逃避反應時的瞬間最大壓力,以測定動物機械鈍痛的痛覺閾限。


與熱痛不同,鼠爪壓力疼痛測痛用于機械壓痛和鈍痛的痛覺測量,常用于辨別左右爪不同的痛覺反應,多涉及脊髓神經過程,人工辨別動物縮腿反應,并用踏板控制馬達的起止。


鼠爪壓力疼痛測試儀的主要特點: 

適用于大鼠和小鼠

精確度為0.1克,最大壓力400

數字顯示功能

配置腳踏控制器

RS-232輸出


爪體積測量儀用來衡量消炎藥的有效性。使用時,講大鼠、小鼠的爪子浸入含有特殊細胞的水中由于浸泡水的壓力發生了變化。壓力的變化會被校準,并顯示在特殊的電子監視器上。這種檢測形式可以消除由于重復浸入發生導電性的改變而產生的改變,這種情況在類似的其他儀器上發現過。測試結果直接顯示在LCD上(大鼠精確到0.01毫升、小鼠精確到0.001毫升)。無論是用電池還是用9V12V的適配器,該設備表現穩定,操作安全

 

鼠爪腫脹測定儀的主要特點: 

無需潤濕液,可消除由于重復浸入發生導電性的改變而產生的體積誤差 

配備90°角的全透明亞克力操作支架,可進行清晰方便

維護方便,不需要特殊的護理液

數據準確,不需要每次使用校準,每年僅需校正一次

具有內置電源,實現停電不間斷操作

帶LCD顯示器,讀書方便

體積精確度:0.01ml(大鼠)0.001ml(小鼠)


鼠抓力測量儀可用于小鼠或大鼠系統測試的使大鼠或小鼠釋放的抓力。常用于藥物、毒物、肌肉松弛藥、衰老、神經損傷對肌力的影響。將大鼠或小鼠置于有機玻璃平臺上,在抓力吊架前面。嚙齒動物會本能地抓取任何東西,以嘗試去停止這種被動的反向運動這將會持續抓吊臺,直到牽力克服了抓力為止。動物失去其抓力后,力峰值前級放大器會自動地儲存峰值的抓力,并顯示在液晶板上。


大小鼠抓力測量儀的主要特點

拉力傳感器最大力度值≥1500g 

最大力可允許超過數值≥150g

讀數精度為0.1g

配備有專用基座、金屬套桿和傳感器Hub

配大小鼠網格和T形桿

陽極電鍍處理的面板,并配備有固定吸盤

配備36g砝碼校準模塊

數據采集器自帶電源,可供數據采集器時間≥250小時

帶Clear清零鍵,使用方便


Our newest addition to our Analgesia line can perform the Electronic von Frey, Digital Randall Selitto, Plethysmometer and Grip Strength Meter test with one electronic system.

Order any one of the test systems complete and the only additional item(s) needed are the individual modules to perform each test.

Electronics has up to three inputs allowing users to perform four very different tests with one electronic system when studies call for doing so.

All data is stored and displayed in the electronics supplied.


Part# 2650 Stand and sling sold separately





Example: 
Order any one of the 2390 Series Electronic von Frey systems; add on either or both the Digital Paw Pressure Applicator only and/or the glass stand setup only and you have a system that is complete for all three individual tests.

A wonderful addition to any laboratory facility studying analgesic compounds in research.

Stand and animal sling for Randall Selitto test sold separately.
