Description
Technical Field
The invention relates to the technical field of detection equipment, in particular to an auxiliary device for touch detection.
Background
Tactile test tactile tests include mobility tactile and immobilization tactile. The objective of the mobile tactile test is to measure the condition of the nerve endings distribution of the rapidly adapting fiber and receptor system. The fixed tactile test is a condition that measures the nerve terminal distribution of the slow adaptive fiber and receptor system.
Typically we use a two-point discriminator for the tactile test. The two-point discriminator is a set of two octagonal films, and each side is provided with a pair of metal branches with different distances of 1-15 mm. The tactile test is generally carried out starting from metal branches with a spacing of 9 mm. If the patient can feel it, then turn to a smaller pitch metal branch; if the patient cannot feel it, the patient turns to a metal branch of greater spacing. When the fixity touch test is carried out, the pair of metal branches is placed on the far-end interphalangeal joint in the direction vertical to the long axis of the finger, and if the distance between the metal branches exceeds the thickness of the finger, the pair of metal branches is placed in the direction parallel to the long axis of the finger. When conducting the mobile touch test, the metal branch should be placed at the distal end of the interphalangeal joint in a direction perpendicular to the long axis of the finger, and then slowly pulled toward the tip of the finger (i.e. from the proximal end to the distal end).
In the fixed touch test or the movable touch test, the force of the metal branch pressing on the finger is just enough to enable the patient to have enough touch feeling, and the excessive force is not applied to cause pain or stab a skin flap or skin graft of the patient. The mobile tactile tone test helps to evaluate some hand functions and activities that require mobile tactile sensation, such as object recognition, button-fastening. The fixity touch test is helpful for evaluating activities which need static touch and accurate gripping in daily life, such as writing with a pen, taking a needle for sewing, unlocking with a key and the like.
The existing touch detection equipment has a large area, so that skin grafting at the position of a finger web (toe web) of a patient can affect other fingers (toes), and the result of sensory measurement generates errors or the precision cannot be guaranteed.
