產(chǎn)品詳情

Von Frey纖毛機(jī)械刺激針遵循Semmes-Weinstein(賽姆斯-韋恩斯坦)測(cè)試?yán)碚撨M(jìn)行設(shè)計(jì),可進(jìn)行精細(xì)的觸覺檢查,可以測(cè)定從輕觸覺到深壓的感覺。


Von Frey纖毛機(jī)械刺激針也可叫做Touch-Test單絲測(cè)試盒、Semmes-Weinstein觸覺測(cè)量尼龍絲,能測(cè)試和評(píng)估感覺水平,Touch-Test™單絲的力量值在5%的標(biāo)準(zhǔn)偏差范圍內(nèi),測(cè)試感覺水平。




利用Touch-Test™單絲感覺測(cè)試套裝來(lái)測(cè)試感覺水平,可以準(zhǔn)確報(bào)告正在減少或恢復(fù)的感覺;
測(cè)試根據(jù)預(yù)先設(shè)定力的5%的標(biāo)準(zhǔn)偏差進(jìn)行;

當(dāng)達(dá)到峰值力閾值時(shí),測(cè)試筆的單絲呈彎曲形狀;
的手柄設(shè)計(jì),Touch-Test™單絲可以打開和回收90°角,方便測(cè)試和收納;
手指凹痕設(shè)計(jì),具有牢固和舒適的手感;
單絲測(cè)試筆手柄上標(biāo)有相應(yīng)的壓力水平的顏色和編碼;
測(cè)試結(jié)果可以記錄在單獨(dú)出售的手部或腳部篩查表格上;
有5件套手部套件裝,6件套足部套件裝和20件套裝可供選擇;

20種單絲規(guī)格和所表達(dá)的力度值:

1.65(0.008g)、2.36(0.02g)、2.44(0.04g)、2.83(0.07g)、3.22(0.16g)、3.61(0.4g)、3.84(0.6g)、4.08(1.0g)、4.17(1.4g)、4.31(2.0g)、4.56(4.0g)、4.74(6.0g)、4.93(8.0g)、5.07(10.0g)、5.18(15.0g)、5.46(26.0g)、5.88(60.0g)、6.10(100.0g)、6.45(180.0g)、6.65(g)。

不同顏色代碼代表不同的壓力級(jí)別:

1.65-2.83對(duì)應(yīng)正常 Normal
3.22-3.61對(duì)應(yīng)輕觸覺減退 Diminished Light Touch
3.84-4.31對(duì)應(yīng)保護(hù)性感覺減退 Diminished Protective Sensation
4.56-6.45對(duì)應(yīng)保護(hù)性感覺喪失Diminished Protective Sensation
6.65用于深層感覺檢測(cè)Deep Pressure Sensation Only
 
有手部感覺測(cè)試型、足部感覺測(cè)試型和全規(guī)格測(cè)試型可供選擇:
手部套件包含:2.83, 3.61, 4.31, 4.56 ,6.65 五種測(cè)試單絲,型號(hào):NC12772
足部套件包含:2.83, 3.61, 4.31, 4.56, 5.07, 6.65六種測(cè)試單絲,型號(hào):NC12773
全規(guī)格套件包含:所有二十種單絲測(cè)試---推薦配置,型號(hào)NC12775-99





Touch Test


The Semmes-Weinstein monofilaments provide an approximate logarithmic scale of actual force, and a linear scale of perceived intensity. They have a long history of effective use in clinical settings, and can be used to diagnose pathologies of hyper- or hypo-aesthesia. Subsets within the set of 20 probes distinguish pathologies on different parts of the body (foot, hand, lip, cheek,etc.).

Semmes-Weinstein Von Frey Aesthesiometer for touch assessment


Features


Set of 20 monofilaments based on the Semmes-Weinstein monofilament set

Features retractable filaments to protect the filament

Allows the researcher to carry a few in a pocket

The Semmes-Weinstein monofilaments provide an approximate logarithmic scale of actual force, and a linear scale of perceived intensity. They have a long history of effective use in clinical settings, and can be used to diagnose pathologies of hyper- or hypo-aesthesia. Subsets within the set of 20 probes distinguish pathologies on different parts of the body (foot, hand, lip, cheek,etc.).


Operating Principle When the tip of a fiber of given length and diameter is pressed against the skin at right angles, the force of application increases as long as the researcher continues to advance the probe, until the fiber bends. After the fiber bends, continued advance creates more bend, but not more force of application. This makes it possible for the researcher using a hand-held probe to apply a reproducible force, within a wide tolerance, to the skin surface.


Pre-Clinical Use Rodents exhibit a paw withdrawal reflex when the paw is unexpectedly touched. The Touch Test? Sensory Evaluator can be used on the Plantar surfaces of the foot of a rat or mouse. The animal indicates sensation by pulling back its paw. Individual filaments available.
