Detailed Description

The technical solution of the present invention will be clearly and completely described below with reference to the accompanying drawings of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Example 1

One embodiment of the present invention is shown in fig. 1. In this embodiment, the neurorehabilitation evaluating apparatus includes a base plate 1 having a cross bar 2 parallel to both long sides 1a of the base plate 1, and the cross bar 2 is fixedly connected to the base plate 1 by a vertical bar 3, thereby constituting a basic structure like a parallel bar. The substrate 1 has a plurality of pressure-bearing units 4 distributed in a matrix on the plane thereof, and preferably, the pressure-bearing units 4 are distributed over the entire plane of the substrate 1, thereby forming a "lattice" of pressure-bearing units 4 thereon. The pressure bearing unit 4 is provided with a rectangular surface 4a parallel to the substrate 1 on the side away from the substrate 1, the pressure bearing unit 4 is in contact with the substrate 1 through a pressure sensor 5, in one embodiment, the lower surface of the pressure bearing unit 4 is in transmission contact with the input end of the pressure sensor 5, and the surface of the pressure sensor 5 opposite to the input end is fixed on the substrate 1, so that when a user tramples on the rectangular surface 4a, the trampled pressure can be collected by the pressure sensor 5, and the pressure when the pressure bearing unit 4 moves downwards relative to the substrate 1 is detected. As a modification, the rectangular surface 4a may be provided with a pattern for preventing slipping.

In order to ensure that the relative positions of the plurality of pressure-bearing units 4 distributed in a matrix in the plane direction of the substrate 1 are maintained unchanged, in this embodiment, the pressure-bearing units 4 are not directly fixed by, for example, positioning pins or the like, but as shown in fig. 2, more than 2 positioning through holes parallel to the wide side 1b of the substrate 1 are formed on the pressure-bearing units 4, in particular, at positions close to the rectangular surface 4a, and a force-bearing unit 6 formed by a metal wire material such as a steel wire, an organic material wire material such as a nylon rope or a rubber strip is used to penetrate through the positioning through holes, and two ends of the force-bearing unit 6 are fixed on the substrate 1, so that the relative positions of the plurality of pressure-bearing units 4 in the plane direction of the substrate 1 are maintained unchanged. In this way, the pressure-receiving unit 4 can be regarded as being placed on the substrate only by the supporting function of the pressure sensor 5, so that the measurement accuracy and the timeliness of the pressure are greatly improved, and the force-receiving unit 6 only plays a role of maintaining the position of the pressure-receiving unit 4 in the plane direction, does not apply force to the direction perpendicular to the plane, and does not affect the pressure measurement result.

The pressure receiving unit 4 has a tetragonal shape by having a rectangular surface 4a, and in one embodiment, a long side 4aa of the rectangular surface 4a is parallel to the long side 1a of the substrate, so that one pressure receiving unit 4 may correspond to one foot of the user. The size of the rectangular surface 4a is not particularly limited, but from the viewpoint of finely dividing the substrate area and improving the pressure measurement accuracy, the width of the rectangular surface 4a is preferably 1/8 to 1/15 of the width of the substrate 1 (i.e., the length of the wide side 1b of the substrate 1) and the length is preferably 1/15 to 1/25 of the length of the substrate 1 (i.e., the length of the long side 1a of the substrate 1). Preferably, the substrate may be divided into finer lattices by using square rectangular surfaces 4a, and the sides of the rectangular surfaces 4a may be 1/8 to 1/25 of the width of the substrate 1.

In order to achieve an output for the pressure, the pressure sensor 5 is electrically connected to the control device.

The operation of the neural rehabilitation evaluation device in this embodiment will be described below. A user holds the cross rod 2, feet step on the substrate 1 and walk in parallel, and therefore pressure perpendicular to the plane of the substrate is generated on the corresponding pressure bearing units 4 below the feet. After being captured by the pressure sensor 5, the pressure is transmitted to the control device through the circuit, so that the control device can acquire and obtain the foot pressure distribution situation of the user in space and time, the foot pressure distribution situation is used for representing the walking posture, the leg force exerting degree, the force exerting uniformity, the force exerting durability and the like of the user, the foot pressure distribution situation can be further compared with the data of normal people walking on the device (the data can be data built in the control device or real person data acquired on site and the like), and the foot pressure distribution situation is used for evaluating the nerve rehabilitation degree of the user. By further reducing the size of the pressure receiving unit 4 formed in a matrix, it is possible to detect the local force applied to the foot of the user. In addition, since the pressure bearing unit 4 is directly contacted with the pressure sensor 5, no interference of other limiting devices or supporting devices and the like exists, and therefore, accurate and quick response can be made to small force changes of a user.

Example 2

As shown in fig. 3, in addition to embodiment 1, in order to further stabilize the position of the pressure-bearing unit 4, the pressure-bearing unit 4 may further include an auxiliary positioning through hole 7 parallel to the long side 1a of the substrate 1, and an auxiliary force-bearing unit 8 passes through the auxiliary positioning through hole 7 and has both ends fixed to the substrate 1, so that the relative positions of the pressure-bearing units 4 in the plane direction of the substrate 1 are maintained unchanged. Similar to the embodiment 1, the auxiliary positioning through hole 7 is preferably arranged at a position close to the rectangular surface 4a, and the material of the auxiliary bearing unit 8 can be the same as or different from that of the bearing unit 6.

Example 3

Although examples 1 and 2 can respond to slight pressure changes, the pressure applied to the pressure-bearing unit 4 is significantly different from that applied to the later stage of rehabilitation, considering that the force applied by the user is different in different stages of the rehabilitation process, for example, the user needs to cooperate with the suspension system to walk in the early stage of rehabilitation, and the shoulder part of the user is lifted by the belt and the leg part of the user is relieved. In consideration of the fact that the electrical components such as the pressure sensor 5 have an operating curve and must be convertible into a pressure value within a specific pressure range according to the output electrical signal, a function of adjusting the pressure is required to improve the universality of the device. In the present embodiment, as shown in fig. 4, a plurality of blind holes 9 are formed in the pressure-bearing unit 4, the opening direction of the blind holes 9 faces the substrate 1, and an elastic member 10, such as a metal spring with a specific pressure grammage, is disposed in the blind holes 9. The elastic member 10 shares the force applied to the pressure sensor 5, so that the pressure sensor 5 having a higher sensitivity but a smaller range can be used, and when used, the actual pressure value can be obtained by simply converting the grammage of the pressure sensor 5 into the specific grammage of the pressure applied to the elastic member 10, for example, by multiplying the detected pressure of the pressure sensor 5 by the grammage of the pressure applied to the elastic member 10. As an improvement, a limiting rod 11 matched with the blind hole 9 may be further disposed on the substrate 1, the elastic component 10 is sleeved on the limiting rod 11 and inserted into the corresponding blind hole 9 together with the limiting rod 11, and the top end of the elastic component 10 is higher than the top end of the limiting rod 11. This can further improve the stability of the bearing unit 4.

Example 4

On the basis of the foregoing embodiments, the present embodiment further follows this approach. As shown in fig. 5, the rectangular surface 4a is provided with a pressure-bearing unit electrode 12 in a surface direction away from the substrate 1, and the pressure-bearing unit electrode 12 is electrically connected with a control device, so that the electric signal is measured and collected for the foot of the user. Preferably, the pressure-receiving cell electrode 12 covers 80% or more of the area of the rectangular surface 4 a.

With it supporting, be provided with horizontal pole electrode 13 on the horizontal pole 2, perhaps other photoelectric equipment that have human monitoring function to be connected with the controlgear electricity, thereby carry out the measurement and the collection of signal of telecommunication to user's hand. Therefore, in the using process of the device, the distribution of the foot pressure of the user over time and the distribution of the area can be obtained, and the information of the heart rate, the blood oxygen content, the blood pressure and the like of the user corresponding to the time point can be obtained, so that more information is provided for the nerve rehabilitation evaluation process.

The above description is only for the specific embodiments of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art can easily conceive of the changes or substitutions within the technical scope of the present invention, and all the changes or substitutions should be covered within the scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the appended claims.
