Description

sensory rehabilitation detector

technical field

The invention relates to a sensory rehabilitation detection tool, especially a sensory rehabilitation detection instrument with point positioning function, which is used to evaluate and train patients who have lost consciousness due to stroke or brain injury.

Background technique

In the medical field, sensory rehabilitation testing plays an extremely important role in the study of central nervous system reconstruction and its plasticity. Sensory rehabilitation therapy is to use the plasticity at the central level to correct and rebuild the sensory disturbance or deviation caused by peripheral nerve damage through re-education of object recognition and cognition. Therefore, the purpose of sensory rehabilitation testing is to improve the recognition of objects, to evaluate and train patients who have lost consciousness due to stroke or brain injury, and to improve and improve the recognition of objects for these patients. Usually, according to the patient's condition, the means of sensory rehabilitation detection clinically used for patients will also be different. For example, the number of moving objects and the number of recognition can be used to evaluate the patient's recognition of objects within a certain period of time. Among them, the traditional sensory rehabilitation detection method is to manually stimulate the patient's palm with the help of a blunt probe, but this method can only provide a very rough indication, and its accuracy is very dependent on the experience and skills of therapists. Therefore, the results provided by this traditional method are not precise enough, and it is difficult to perform repeated evaluation, so it is difficult to accurately record and judge the patient's recovery.

According to the statistics of the World Health Organization (WHO), the number of stroke patients continued to increase from 38 million in 1990 to 61 million in 2002. There were 2.7 million stroke patients living in Asia in 2002, and 1.6 million of them were Chinese. As the number of stroke patients has greatly increased, the demand for health care and sensory rehabilitation testing tools for this population will also increase significantly.

For this reason, what kind of sensory rehabilitation testing tool to use is an urgent research topic for people in the medical field.

Detailed ways

The sensory rehabilitation detector of the present invention will be described in detail below according to preferred embodiments of the present invention.

Fig. 1 is a three-dimensional schematic diagram of a sensory rehabilitation detector 100 according to the present invention; Fig. 2 is a perspective schematic diagram of another angle of the sensory rehabilitation detector 100 according to the present invention; Figs. 3A-3E are sensory rehabilitation detectors according to the present invention Front view, left view, right view, top view and bottom view of the instrument.

As shown in the figure, the sensory rehabilitation detector 100 is designed in a shape similar to a mouse, so that the patient's hand can be placed on it, and has a shell, which can be translucent or transparent, or opaque The housing can be coated with a coating, for example, the housing material can be ABS material with a white coating on it. The housing includes an upper housing 101 and a lower housing 102. The upper housing 101 is ergonomically designed as a curved surface that matches the hand, and the front end of the upper housing 101 is provided with a recess 105 for placing fingers. And a silicon platform 103 is provided at the rear of the upper housing 101 to reduce the pressure from the wrist to the forearm generated by the positioning pins when using the sensory rehabilitation tester 100 . The lower case 102 can be fixed to the upper case 101 by various known fasteners. A printed circuit board module 20 that can be inserted into the housing is provided on one side of the housing. This plug-in design facilitates detection of the printed circuit board module 20 and is easy to replace. Of course, the printed circuit board module 20 can also be designed as a fixed type, which can be fixed on the inner surface of the lower case 102 .

It can also be seen from the drawings that a plurality of manually operable and adjustable control buttons 30 are provided on the other side of the housing, such as switch on/off power button, mode control button and the like. In addition, a predetermined pattern, that is, a standard test pattern, is provided on the upper casing 101 , and the pattern may be composed of fifty-three circular through holes 104 of the same size and arranged in a "m" shape. However, the shape and arrangement of the through holes 104 on the upper housing 101 of the sensory rehabilitation tester 100 are not limited to this embodiment, and they can also be designed as standard test patterns in other shapes and arrangements. Adopting the design of the standard test pattern on the upper housing 101 can make the sensory rehabilitation tester 100 different from the traditional way of manually stimulating the patient's palm with only a blunt probe, which can not only provide accurate results, but also Repeated evaluations are performed through predetermined modes of operation. Wherein, at least one probe 503 can protrude from the through hole 104 . Since the shape of the upper shell of the sensory rehabilitation detector of the present invention is designed according to ergonomics, the height of each positioning pin 503 can be set by a microcontroller system, so that each positioning pin 503 can be stretched out. The lengths of the curved surfaces of the upper case 101 are the same, and are all about 3-4 mm. Additionally, positioning pin 503 may be controlled to have at least one predetermined mode of operation.

The control method of the positioning pin 503 will be described below with an example. According to design requirements, the movement of the positioning pin 503 can be set to have different predetermined operation modes. For example, in this embodiment, the oval-shaped button in the control buttons 30 is designed as a mode control button, which can control a plurality of predetermined operating modes. For example, two predetermined operation modes are controlled, one of which can control the positioning needle 503 away from the central positioning needle to move up and down randomly or with a predetermined rule. In this mode, the central positioning needle can be used as a reference point, requiring the patient to determine whether the positions of the positioning pins 503 moving up and down touching their palms are the same or different; while another mode may control the positioning pins 503 near the central positioning pin to randomly or in another way. Predetermined regular movement up and down, in this mode, can also use the central positioning pin as a reference point, requiring the patient to determine whether the positions of the positioning pins 503 touching their palms moving up and down are the same or different. As can be seen from the two modes listed above, when the positioning pins 503 are arranged in a "meter"-shaped pattern, the positioning pins set in the second mode move up and down to stimulate the palm and the center positioning pins as a reference The distance is closer, so the second mode is more difficult to judge than the first mode. Of course, in the present invention, there is no restriction on the types of operation modes of the positioning needle 503 in principle, and designers can design three, four or more operation modes according to design requirements, and even adopt A random pattern is used to control the up and down movement of the positioning pin 503; and other positioning pins in typical positions or a specific position can be used as a reference, so as to perform appropriate use according to the individual condition of the patient.

According to the introduction of the above structure, it can be seen that the sensory rehabilitation detector 100 of the present invention is very convenient for the treatment personnel to operate and the patient to hold, and this structure is light and easy to carry, so it is very convenient to use and operate. In addition to being able to perform such a test in a hospital, patients can also perform the test themselves at home. In addition, since the patient can be tested in a predetermined mode of operation and the test results can be accurately recorded, repeated evaluation of the patient's recovery can be performed to obtain a more accurate judgment.
