     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT 
       [0031]    Embodiments of the present invention will now be described in detail with reference to the accompanying drawings. The invention may, however, be embodied in many different forms and should not be construed as being limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art. In the drawings, the shapes and dimensions of elements may be exaggerated for clarity, and the same reference numerals will be used throughout to designate the same or like components. 
         [0032]    The invention provides a strap sticker for body adhesion. The composition of the strap sticker is designed optimally for a force bearing extension level of the strap sticker to be identified by naked eyes directly, such that the strap sticker may be utilized without assistance of medical personnel, and thereby, the vision of home use is further achieved. 
         [0033]    Refer to  FIGS. 1 ,  2 ,  3 A and  3 B, which are schematic views showing the strap sticker for body adhesion according to the invention. As shown in the figures, the strap sticker  1  of the invention includes an elastic body  11 , a glue film  12  and a comparative object  13 . The elastic body  11  is provided with a force showing pattern  114  formed by a through hole of the elastic body  11  or pigment marked on the elastic body  11 . The force showing pattern  114  may be of circle, ellipse, polygon or other combined shape, or other pattern shapes with special visual effect. 
         [0034]    The glue film  12  is a surface laid on the elastic body  11  opposed to the force showing pattern  114  for providing viscosity to be glued on skin of user. The comparative object  13  shown in  FIG. 2  is marked with comparative patterns  131 ,  131 ′,  131 ″, which are used to provide shape comparison of the force showing pattern  114  after the elastic body  11  bears force for force bearing extension level of the elastic body  11  to be determined. The comparative object  13  may be a release paper covering above the glue film  12 . Even more, the comparative object  13  may also be, for example, outer packing box, packing paper, user manual, medicine sheet or any paper marked with pattern. The release paper may provide protection of glue film for the unused elastic body  11 . As shown in  FIG. 2 , which shows a comparative object marked with comparative patterns. In  FIG. 2 , the multiple comparative patterns  131 ,  131 ′,  131 ″ marked on the comparative object  13  correspond to shapes of the observation well  131  as the elastic body  13  is at L 1 , L 2 , L 3  extension levels, respectively. Wherein, symbols L 1 , L 2 , L 3  represents that the elastic body  13  has extension levels with 130%, 150%, 170% extension rates, respectively. 
         [0035]    Further, refer to  FIGS. 4A ,  4 B and  5 , which are schematic views showing one implementation according to the invention. As shown in  FIG. 4A , the strap sticker of the invention includes an elastic body  11  and a glue film  12 . The elastic body  11  may be a multi-layer structure with different elastic coefficients. In the implementation, the elastic body  11  has an outer layer  111  and an inner layer  112 , and an observation well  113  penetrating through the outer layer  111  and the inner layer  112 . Preferably, the inner layer  112  is mixed with a pigment different from color on the outer layer  111 , and the elastic coefficient of the inner layer  112  is larger than that of the outer layer  111  such that a material with color different from the outer layer  111  is exposed in the observation well  113  to construct a force showing pattern in the observation well  113  as the inner layer  112  is extended due to force bearing of the strap sticker  1 . It should be noted that the more the material of the inner layer  112  exposed in the observation well  113  is, the larger the force bearing at the two ends of the strap sticker  1  is, that is, the extension level of the strap sticker is larger. As such, the force bearing extension level of the strap sticker  1  is identifiable with the exposure status of the inner layer material in the observation well  113 . The area indicated by symbol Z shown in  FIG. 4B  is the material of the inner layer  112  exposed in the observation well  113 . 
         [0036]    The elastic body  11  may be made of natural fiber material, synthetic fiber material or the arbitrary combination thereof. Preferably, the elastic body  11  may be made of PU (Polyurethane), PE (Polyethylene), PP (Polypropylene), PVC (polyvinyl chloride), EVA (Ethylene Vinyl Acetate copolymer), EAV (Ethylene Vinyl Acetate copolymer), PVA (poly vinyl alcohol), Nylon (Polyamide), TPU (Thermoplastic Polyurethane), PET (Poly(ethylene terephthalate)) or the arbitrary combination thereof. The elastic body  11  includes further a antibacterial material for bacterial removal or bacterial growth prevention; the antibacterial material includes, but not limited to, nanometer silver grain, quaternary salt, chitosan or the combination thereof. 
         [0037]    The opening shape of the observation well  113  may be circle, ellipse, polygon, irregular shape or other shape with special visual effect. As the strap sticker  1  bears force to extend, the opening of the observation well  113  will change corresponding to the force bearing level of the strap sticker  1 . Thus, the force bearing extension level of the strap sticker  1  may be determined with the opening shape of the observation well  113 . 
         [0038]    The elastic body  11  shown in  FIG. 4A  is a three-layer structure, but the invention is not limited thereto, and the layer number of the elastic body  11  may also be changed properly according to the requirement of rehabilitation treatment. Refer to  FIG. 5 , which is a schematic view showing the usage status of the strap sticker attached to body after being extended to a certain level due to force bearing. The wall of the observation well  113  as shown in  FIG. 5  is an inner layer material exposed to outside with circular extension to construct a force showing pattern. 
         [0039]    The glue film  12  is laid on the surface of the outer layer  111  of the elastic body  11  for adhesion to skin of user. The glue film  12  has to be a material that does not induce inappropriate situation such as allergic reaction to human skin, including, but not limited to, silicone, acrylic adhesive or the combination thereof. The glue film  12  may be laid over a local surface area of the elastic body  11  in wave form (as shown in  FIG. 10 ) or concentric form such that buckling is generated on skin as the glue film  12  is attached to the skin, and thereby, blood circulation is improved, metabolism is improved, muscle soft tissue is supported or stretched effectively to achieve the function with respect to protection of muscle soft tissue. 
         [0040]    Refer to  FIGS. 6A ,  6 B,  7 A,  7 B, which are schematic views showing an implementation of the strap sticker according to the invention.  FIGS. 6A and 6B  show the status as the strap sticker does not bear force to extend.  FIGS. 7A and 7B  show the status as the strap sticker bears force to extend and exposes the extension level identification tag. As shown in the figures mentioned above, the strap sticker  1  of the implementation is provided with an extension level identification tag  15 , which is extended from the inner layer  112  and may be exposed to the observation well  1  by the extended and deformed inner layer  112  as the strap sticker  1  bears force. The more the portion of the extension level identification tag  15  exposed to the observation well  1  is, the larger the force bearing extension level of the strap sticker  1  is. Preferably, the portion or the surface of the extension level identification tag  15  exposed to the observation well  113  may be marked with text or pattern for identifying the current force bearing extension level of the strap sticker  1 . 
         [0041]    In  FIG. 6A , the well diameter of the observation well  113  in the inner layer  112  is larger than that in the outer layer  111  such that an indent space  1131  is formed inside the observation  113 . As the elastic body  11  does not bear force for extension, the extension level identification tag  1111  may be indented in the indent space  1131  to reduce the level with respect to exposure to the observation well  113 , and expand scenic difference in the observation well  113  before and after the strap sticker  1  bears force to extend, such that the current force bearing extension level of the strap sticker  1  may be identified more effectively. 
         [0042]    Also, refer to  FIGS. 8A ,  8 B,  9 A and  9 B, which are schematic views showing another implementation of the strap sticker according to the invention. In the implementation, the strap sticker  1  is provided with a force showing bar  14  for responding to the extension level of the elastic body  11 . As shown in  FIGS. 8A ,  8 B, the strap sticker  1  in the implementation is provided with a force showing bar  14  extended on opposed walls on two sides to separate the opening of the observation well  113  into multiple areas. The force showing bar  14  has a structurally weak point with respect to the reaction to the extension level of the elastic body  11 . The structurally weak point indicates the part with smaller thickness in the force showing bar  14  (as shown in  FIG. 8A ), or the part with smaller cross sectional area (as shown in  FIG. 9A ), or the part with smaller strength (not shown). As the strap sticker  1  is extended due to force bearing on two ends, forces are conducted to the force showing bar  14  simultaneously until the force showing bar  14  is broken on the structurally weak point, as shown in  FIGS. 8B ,  9 B. As such, whether the extension of the strap sticker  1  has achieved a predetermined extension level is identifiable with the observation about whether the force showing bar  14  is broken. 
         [0043]    In conclusion, there are the following features of the strap sticker for body adhesion according to the invention: 
         [0044]    1. One or more observation wells are provided in the strap sticker such that the force bearing extension status of the strap sticker is identifiable visually by the change with respect to the shape of the opening in the observation well to meet the goal of using the strap sticker for home use. 
         [0045]    2. A force showing pattern with shape changeable according to the force bearing extension of the elastic body is provided on the outer surface of the strap sticker such that the force bearing extension level of the strap sticker may be determined effectively by the force showing pattern along with the comparative pattern marked by the comparative object. 
         [0046]    3. The force showing bar or the extension level identification tag are extended in the wall of the observation well of the strap sticker such that the identification for the force bearing extension status of the strap sticker is more direct by the exposure of the force bearing bar or the extension level identification tag in the observation well.
