[0036] The following is a clear and complete description of the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings in the embodiments of the present invention. In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention can also be implemented in other ways different from those described herein, and those skilled in the art can make similar generalizations without violating the connotation of the present invention, so the present invention is not limited by the specific embodiments disclosed below.
[0037] First embodiment
[0038] like Figure 1 As shown, it is a structural schematic diagram of the first embodiment of the dot matrix imprinting dynamic testing device of the utility model. The dot matrix imprinting dynamic testing device of this embodiment is provided with an elastic pad 10, a transparent plate 20 and a camera device 50. The camera device 50 is located below the transparent plate 20, and there is a certain distance between the camera device 50 and the transparent plate 20. The camera device 50 is used to capture image information on the transparent plate 20. The elastic pad 10 is movably located on the upper surface of the transparent plate 20. The elastic pad 10 is provided with a body 101 and a convex point array located on the bottom surface of the body 101. The convex point array is composed of a plurality of elastic convex points 102. A light bar 201 is provided on any one side or multiple sides of the transparent plate 20. Specifically, in this embodiment, a light bar 201 is provided on one side of the transparent plate 20. The light bar 201 is an LED lamp, a fluorescent lamp or a laser. The transparent plate 20 is a quartz glass plate, a tempered glass plate or a transparent acrylic plate. The structure or material of the light bar 201 and the transparent plate 20 is not limited thereto, and any structure that can realize the reflection of light by an object on the transparent plate 20 is included.
[0039] Please refer to Figure 2As shown, it is a schematic diagram of the structure of the elastic pad 10 of this embodiment. The elastic protrusion 102 of the elastic pad 10 of this embodiment is provided with an end structure 103. The cross section of the end structure 103 decreases in the direction away from the body 101. The elastic protrusion 102 is made of an elastic material with a certain hardness, such as rubber, silicone and other similar materials. The size, diameter and distribution density of the elastic protrusion 102 are set according to requirements, and are evenly spaced on the lower bottom surface of the body 101. In addition, the material of the body 101 of the elastic pad 10 is selected from an elastic material with a certain hardness to ensure that it will not be stretched or deformed when subjected to pressure, and at the same time, the force applied thereto can be transmitted downward. Specifically, two basic requirements must be met:
[0040] (1) When pressure is applied thereto, it will not stretch or deform in the plane, thereby ensuring that the spacing between the elastic bumps 102 in the bump array on the bottom surface thereof remains unchanged;
[0041] (2) On the basis of not deforming under force, the body 101 can also serve as a force transmission component to transmit the force applied thereto to the elastic protrusion 102, thereby ensuring that the elastic protrusion 102 is deformed, and the strength of the deformation is positively correlated with the magnitude of the force applied to the corresponding part of the body 101.
[0042] It can be understood that the material of the main body 101 is selected from an elastic material with a certain hardness. For example, the main body 101 can be made of a material similar to that used to make basketballs (the thickness of the main body 101 is thinner than that of the material used to make basketballs). Alternatively, the main body 101 can be made of a composite material similar to cloth and rubber that is softly bonded to give it a flexible and soft property.
[0043] The working method and principle of this embodiment are as follows: when testing a certain part of a patient, the elastic pad 10 is placed on the upper surface of the transparent plate 20, wherein the side provided with the elastic convex point 102 faces the transparent plate 20. Here, taking the test of the patient's foot as an example, the foot applies force to the body 101 of the elastic pad 10, and the body 101 transmits the force to the elastic convex point 102. After being pressed, the elastic convex point 102 abuts against the upper surface of the transparent plate 20. Since the lower end of the elastic convex point 102 is a structure close to a "point", a pressing point is formed on the transparent plate 20. A light strip 201 is provided on the side of the transparent plate 20. Since the light source of the light strip 201 completely passes through the inside of the transparent plate 20, the end point structure 103 of the elastic convex point 102 The portion abutting against the transparent plate 20 will reflect the light source, and since the pressure of the foot at different positions on the elastic pad 10 is different, as the local compressive stress increases, the contact area between the endpoint structure 103 of the elastic protrusion 102 and the transparent plate 20 increases, and a stress dot matrix of different sizes with the distribution of compressive stress is formed on the transparent plate 20. Many stress dot matrices form a dot matrix diagram, and a dynamic image of the stress dot matrix diagram presented by the endpoint structure 103 on the transparent plate 20 in the above process is obtained through the camera device 50 at the bottom, and then the number, distribution and size changes of the "light spots" formed by the endpoint structure 103 collected in the dynamic image are analyzed, so as to analyze the strength of different parts of the patient's foot and use it as a medical test.
[0044] The dot matrix imprinting dynamic testing device of this embodiment, equipped with corresponding equipment, can dynamically test and analyze the contact stress of any surface of the body. It is reusable, non-toxic and harmless, and does not cause damage to the human body. It can be used in hospitals and scientific research institutions, and can also be used in homes. It provides a relatively simple, safe and accurate method for human body mechanics testing such as prosthetic applications, shoe body design, and occupational disease protection. At the same time, it is not limited to testing of human feet, but can also be applied to testing, application and use of other parts of the human body, such as testing hand stress, or testing body stress to detect the presence of bedsores, etc.
[0045] Second embodiment
[0046] like Figure 3 and Figure 4As shown, it is a structural schematic diagram of the second embodiment of the utility model. In this embodiment, the dot matrix imprinting dynamic testing device is also provided with a reflector 30 and a supporting frame 40. The transparent plate 20 is located on the supporting frame 40. The reflector 30 is inclined and located inside the supporting frame 40. The camera device 50 is located on the side of the supporting frame 40 and on the side of the reflecting surface of the reflector 30. The camera device 50 is used to record the image content reflected by the reflector 30. The supporting frame 40 of this embodiment is provided with a bottom plate 401, two support rods 402 and two side plates 403. The support rods 402 and the bottom plate 401 are respectively vertically arranged between the two side plates 403. The support rods 402 are located on the upper end faces of the side plates 403, and the bottom plate 401 is located on the lower end faces of the side plates 403. Preferably, any side of the bottom plate 401 that is perpendicular to the side plates 403 is provided with a groove (not marked in the figure). The groove here is used to fix the bottom of the reflector 30 to prevent the position of the reflector 30 from shifting and affecting the test results.
[0047] The dot matrix imprinting dynamic testing device of the present embodiment has the same working principle as that of the previous embodiment, and the only difference is that a reflector 30 and a support frame 40 are added to the device of the present embodiment, and the position of the camera device 50 is also changed. It is no longer located directly below the transparent plate 20, but is located on the side of the reflective surface of the reflector 30. Specifically, the photographing direction of the camera device 50 is perpendicular to the plane where the reflector 30 is located, so as to obtain a dynamic change diagram of the contact area between the endpoint structure 103 at the bottom of the elastic pad 10 and the transparent plate 20 reflected on the reflective surface. During the use of the present embodiment, it is more convenient to observe the changing state of the pressure on different parts of the elastic pad 10. The reflector 30 reflects the changing state to the side of the support frame 40, and the staff can directly observe it with the naked eye, which is more convenient to use and operate.
[0048] In other embodiments of the present invention, Figure 5 and Figure 6 As shown, the elastic convex point 102 is also provided with a column structure 104, the upper end face of the column structure 104 is connected to the bottom face of the body 101, and the lower end face coincides with the plane of the endpoint structure 103. The column structure 104 here can be a cylinder, a hexagonal prism or a quadrangular prism, and is not limited here. Regardless of the shape, it satisfies that the cross-section of the endpoint structure 103 decreases in the direction away from the body 101, and the lower end face of the column structure 104 coincides with the uppermost plane of the endpoint structure 103. Therefore, after the elastic convex point 102 is subjected to external pressure, a dynamic image in which the abutment area is continuously increased and the abutment surface formed is gradually changed can be formed on the transparent plate 20 through the endpoint structure 103, thereby performing human body stress analysis.
[0049] Through the above technical scheme, the dot matrix imprinting dynamic testing device of the utility model can study the gait or diseased parts of human medicine by capturing the dynamic image changes left on the luminous transparent plate 20 after the human body imprints the elastic pad 10. The device can be used repeatedly and will not cause any pollution during use. In addition, the test results are more accurate.
[0050] Obviously, the described embodiments are only some embodiments of the utility model, not all embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
