Abstract:
This invention is an improved acupuncture device comprising of several cartridges (including a control circuit, a power supply unit, and a power switch in each cartridge) and leads among cartridges. Each cartridge has a conductive clip, which can lock a picking onto the cartridge. Open the power switch to power on the control circuit, and the current will flow to the picking through the clip. Stamp the picking onto an acupoint to excite it with the low frequency current generated by the control circuit. In this way, the device can result in the same effect as needle therapy. Furthermore, due to the flexibility of the leads, the device can be applied on multi acupoints.

Description:
FIELD OF THE INVENTION 
   This invention provides an improved acupuncture device, in particular refers to an acupuncture device simple in structure, portable, and easy to use. 
   BACKGROUND OF THE INVENTION 
   Legacy acupuncture devices generate treatment and health care effect through puncture acupoints with needles. However, they have the following shortcomings or disadvantages:
     1. hard to apply due to the profound expertise;   2. limited to specific environments due to the sanitization process of acupuncture devices;   3. not suitable for timid persons or children due to the potential fear felling resulted from needles.   

   Consequently, some electronic acupuncture devices fulfilling the treatment or health care through exciting acupoints with low frequency current. The principle of this therapy is to excite the nerve fibers in man body with the low frequency electric current to agitate the “nerve induced current”, which has the same waveform as that of the electric current. The structure of a typical acupuncture device mentioned above comprises of a power supply unit and one or more lead extending from the power supply unit to connect to a needle or picking at the other end of each lead. Place the needle or picking on an acupoint, and the device can generate the same therapeutic effect as needle therapy. Though such an acupuncture device is simple in operation, it still has the following shortcomings:
     1. The lead extending from the device may entangle with each other, which may not only result in inconvenience in operation but also failure;   2. Not portable due to its large size;   3. Expensive due to its complicity in structure;   4. May result in failure and hard maintenance work due to the complicity of its circuit.

   DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS 
   The additional purposes and structure of this invention will be further elucidated as follows. Some parts or the arrangement of parts of this invention in different embodiments may be slightly different. However, the embodiments selected in this document will be detailed and illustrated to make the technologies used in this invention more clear. 
   Please see the improved acupuncture device in  FIG. 1 , wherein the device mainly comprises of two cartridges ( 10  and  20  ), electric leads ( 30 ) between cartridge  10  and  20 , and adhesive picking  40  and  50  at the bottom of cartridge  10  and  20 . 
   Please see FIG.  2  and  FIG. 4 , wherein the cartridge  10  is composed of a top cover ( 11 ) and a bottom cover ( 12 ), and the two covers can be locked together with a screw ( 13 ). 
   There is a bulgy structure ( 121 ) at the position of the electric lead ( 30 ) on bottom cover  12 . At each side of the bulgy structure  121  there is a pole ( 122  and  123 ), respectively, which is slightly higher than bulgy structure  121  there is a “∩” shape unit ( 15 ) on pole  122  and  123 , respectively, and each “∩” shape unit ( 15 ) has a sleeve ( 151  and  152 ), which can be fit over pole  122  and  123 . There is a free space between “∩” shape unit ( 15 ) and bulgy structure  221  for the lead  30  to pass through and be clamped there. 
   There is a control circuit ( 14 ) in cartridge  10 , connecting electric lead  30 . On top cover  11 , there are two buttons ( 111  and  112 ) passing through hole  1111  and  1121  and fixed on bulgy pole  113  and  114 , which are fused and compressed together to fix pole  1111  and  1121  and form a free space in hole  115  and  116 . Button  111  and button  112  face against switch  141  and  142  on the control circuit  14 . Press button  111  and  112  to make bulgy pole  1112  and  1122  at the bottom contact with switch  141  and  142  to control these switches. 
   There is a conductive clip between top cover  12  and picking  40 . The conductive clip can be any form, but the buckle structure (bulgy button  41  and concave button  16  ) in the figure is the simplest and easy to implement. In this case, the bulgy button  41  is pressed on picking  40 , and the concave button  16  is fit over the bulgy pole  124  on bottom cover  12  with sleeve ear  161 , The bulgy pole is fused and compressed to fix sleeve ear  161 , which in turn fix concave button  16  on the bottom of bottom cover. The clip unit composed of bulgy button  41  and concave button  16  can press picking  40  with cartridge  10  together. 
   Please see FIG.  3  and  FIG. 5 , wherein the cartridge  20  is composed of a top cover ( 21 ) and a bottom cover ( 22 ), and the two covers can be locked together with a screw ( 23 ). 
   Similar to the bottom cover  12  of cartridge  10 , there is a bulgy structure ( 221 ) at the position of the electric lead ( 30 ) on bottom cover  22 . At each side of the bulgy structure  221  there is a pole ( 222  and  223 ), respectively, which is slightly higher than bulgy structure  221 , there is a “∩” shape unit ( 25 ) on pole  222  and  223 , respectively, and each “∩” shape unit ( 25 ) has a sleeve ( 251  and  252 ), which can be fit over pole  222  and  223 . There is a free space between “∩” shape unit ( 25 ) and bulgy structure  221  for the lead  30  to pass through and be clamped there. 
   There is a battery cell ( 211 ) and an outer cover ( 212 ) on top cover  21 . The outer cover  212  has an “L” shape pin  2121 . Push pin  2121  into the hole ( 211 ) against battery cell  211 ) clamp it into the narrower hole  2112 , and then the outer cover can be fixed, the battery ( 60 ) can be locked in battery cell  21  as well. There are two conductive plates ( 213  and  214 ) in battery cell  211 , contacting with the positive and negative pole of the battery, respectively. Conductive plate  213  and  214  extend into the bottom cover  22  and connect with electric lead  30 . 
   Similar to the bottom cover  12  of cartridge  10 , there is a conductive clip between top cover  22  and picking  50 . The conductive clip can be any form, but the buckle structure (bulgy button  51  and concave button  26 ) in the figure is the simplest and easy to implement. In this case, the bulgy button  51  is pressed on picking  50 , and the concave button  26  is fit over the bulgy pole  224  on bottom cover  22  with sleeve ear  261 . The bulgy pole is fused and compressed to fix sleeve ear  261 , which in turn fix concave button  26  on the bottom of bottom cover  22 . The clip unit composed of bulgy button  11  and concave button  26  can press picking  50  with cartridge  20  together. 
   Please see  FIG. 1  again. When picking  40  and  50  are clamped together with  10  and  20 , respectively, they can be place at two acupoints on man body. The distance between cartridge  10  and  20  depends on the length of the lead  30  (as shown in the figure). Stamp picking  40  and  50  at two acupoints on man body and add power to them by switching on button  111  and  112 , the device can generate the same therapeutic effect as needle therapy with low frequency current controlled by the control circuit.
