Hairs 纤毛机械刺激针 Von Frey Hair Stimulation Needle Von Frey Hairs is a set of 20 Von Frey Hairs Stimulation Needle 机械痛阈或触觉 阈测量 Composition, known in English as Von Frey filaments or Semmes-Weinstein monofilaments, is mainly used for the von Frey test to evaluate the skin's mechanical pain threshold or tactile threshold measurement   , Is a very popular non-invasive experimental equipment.


可提供0.008g-300g的触觉刺激力。 Von Frey ciliary mechanical stimulation needle can provide tactile stimulation of 0.008g-300g. (The von Frey test is easy to use. It can perform quantitative mechanical pain threshold or tactile threshold measurement on a variety of animals, please call for consultation.)

 

Hairs 纤毛机械刺激针 尼龙丝的粗细及伸出长度决定提供触觉von Frey test刺激力的大小。 The thickness and extension of Von Frey Hairs ciliary mechanical stimulation needle nylon filament determines the amount of stimulation provided by the tactile von Frey test. Von Frey Hairs 纤毛机械刺激针 ,调节适当的伸出长度,垂直地刺激皮肤,可通过调节伸长、更换触觉尼龙丝调整刺激力大小,直到触觉测量尼龙丝弯曲。 During the experiment, select the appropriate thickness tactile test Von Frey Hairs ciliary mechanical stimulation needle according to the actual situation , adjust the appropriate extension length, and stimulate the skin vertically. You can adjust the stimulating force by adjusting the elongation and changing the tactile nylon filament until Tactile measurement of nylon wire bending. When rodents get a mechanical or tactile threshold for their claws, they retract and reflect. 机械痛阈或触觉 阈测量 The tactile test can be applied to the plantar mechanical pain threshold or tactile threshold measurement in rats and mice .

 

Von Frey Hairs 纤毛机械刺激针使用时 可选配凿孔工作台,其触觉测量网筛孔是利用激光切冲而成的方形孔,尺寸为5×5mm2 ,触觉测量孔间距约为1mm,这对受试动物而言是一个舒适的环境,也便于操作人员观察动物的足底触觉感应区域。 In addition: Von Frey Hairs ciliary mechanical stimulation needles can be equipped with a chiseling table when used. The tactile measurement mesh screen is a square hole cut and punched with laser. The size is 5 × 5mm2. This is a comfortable environment for the test animal, and it is convenient for the operator to observe the tactile sensing area of the animal's foot. The drilling table is coated, which is easy to clean and not easily corroded.


Human tactile test  


触觉测试笼(老鼠足底触觉痛觉测试凿孔台) Tactile test cages for rats and mice

It consists of two parts, the drilling platform and the squirrel cage. The drilling platform is evenly distributed. It is made of a laser-cut perforated plate holder.
The squirrel cage is made of fully transparent acrylic material, which is ventilated up and down, which is conducive to the observation of the experimenters, and also creates a safe and comfortable test environment for the mice.



固定器(老鼠面部、背部、腹部触觉测试实验固定笼) Pain test rat fixator (mouse face, back, abdomen tactile test test fixed cage)

Can be used for tingling experiments on the face, back, and abdomen of rats;

Can be customized according to the weight of the mouse;


技术参数: The main technical parameters:

 

Von Frey Hairs 纤毛机械刺激针 :no°20 校准偏差小于5% Ø Von Frey Hairs ciliary mechanical stimulation needle : no ° 20 , calibration deviation is less than 5%

von Frey test 刺激力:0.008 -300g Ø von Frey test stimulation: 0.008 -300g

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.).

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. 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.

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. 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.
