In such a manner, the hospital staff is able to control drip rate of the infusion device  1001  of the infusion set  1000  through operation of the control unit F. 
     As shown in  FIG. 3 , the adjustment device C is a cam set  6 ′, the base is a secure member  60 ′, and the movable member is a rotating cam  61 ′ rotatable relative to the secure member  60 ′. The rotating cam  61 ′ includes an axis  610 ′ and a cam body  611 ′. The axis  610 ′ is disposed on a side of the upper infusion tube  2 . The cam body  611 ′ is eccentrically mounted with the axis  610 ′. The cam body  611 ′ presses the wall of the upper infusion tube  2  through rotation of the cam body  611 ′ relative to the secure member  60 ′, so as to vary section of the upper infusion tube  2 . 
     As shown in  FIG. 4 , the adjustment device C is a cam set  6 ″, and the major difference between the cam set  6 ″ shown in  FIG. 4  and the cam set  6 ′ shown in  FIG. 3  is that the base of the cam set  6 ″ is a secure cam  62  instead of secure member. 
     As shown in  FIG. 5 , the adjustment device C is a cylinder set  6 ′″, the base is a holding member  60 ″, and the movable member is a cylinder device  61 ″.

The cylinder head  611 ″ presses the wall of the upper infusion tube  2  through the cylinder head  611 ″ stretching out from the cylinder housing  610 ″, so as to vary section of the upper infusion tube  2 . 
     Please refer to  FIG. 1 ,  FIG. 6  and  FIG. 7 .  FIG. 6  is a diagram illustrating part of the infusion device  1001  in a non-interrupting state according to the first embodiment of the present disclosure.  FIG. 7  is a diagram illustrating part of the infusion device  1001  in an interrupting state according to the first embodiment of the present disclosure. As shown in  FIG. 1 ,  FIG. 6  and  FIG. 7 , the infusion set  1000  further includes a first detecting module  7 . The first detecting module  7  is disposed aside the syringe body  1  and includes a first light emitting unit  70  and a first light receiving unit  71 . The first light emitting unit  70  is disposed on a side of the syringe body  1 , and the first light emitting unit  70  emits a light  73  to the syringe body  1  in a first light path L 1  through a first dripping path D 1  along which the injection  2000  drips from the infusion member  3000  to the inner chamber  10  of the syringe body  1 . The first light receiving unit  71  is disposed on another side of the syringe body  1 . In the present disclosure, the first detecting module  7  can be an infrared sensor module, but the present disclosure is not limited thereto. 
     As shown in  FIG. 6 , when a drip  9  of the injection  2000  on the first dripping path D 1  does not interrupt the light  73  in the first light path L 1 , the light  73  is not refracted by the drip  9 , and the light  73  passes in the first light path L 1 , such that the first light receiving unit  71  receives the light  73  emitted from the first light emitting unit  70  and generates a first light strength signal accordingly. As shown in  FIG. 7 , when the drip  9  of the injection  2000  on the first dripping path D 1  interrupts the light  73  in the first light path L 1 , the light  73  is refracted away from the first light path L 1  by the drip  9 , such that the first light receiving unit  71  does not receive the light  73  emitted from the first light emitting unit  70  and generates a second light strength signal accordingly. 
     Furthermore, the first detecting module  7  is coupled to the control unit F, such that the control unit F processes the first light strength signal and/or the second light strength signal for rendering counts of the drip  9 . For example, the control unit F renders one count of the drip  9  according to the first light strength signal or the second light strength signal received. Alternatively, the control unit F renders one count of the drip  9  as well according to a combination of the first light strength signal and the second light strength signal. In other words, the first light strength signal, the second light strength signal or a combination thereof is rendered one count of the drip  9  of the injection  2000  on the first dripping path D 1 . 
     As shown in  FIG. 6  and  FIG. 7 , the syringe body  1  includes a main portion  11  and an auxiliary portion  12  connected to the main portion  11 . The inner chamber  10  is formed in the main portion  11 , and the first detecting module  7  is disposed aside the main portion  11 . The auxiliary portion  12  has a liquid storage space  13  formed therein. The liquid storage space  13  is communicated with the inner chamber  10 , such that the injection  2000  in the inner chamber  10  is dripped into the liquid storage space  13 . 
     It is noticed that the infusion set  1000  with the first detecting module  7  disposed aside the main portion  11  of the syringe body  1  is illustrated as an embodiment herein, but the present disclosure is not limited thereto. For example, in a second embodiment, the infusion set  1000  includes a second detecting module  8  disposed aside the auxiliary portion  12 . The second detecting module  8  includes a second light emitting unit  80  and a second light receiving unit  81 . The second light emitting unit  80  is disposed on a side of the auxiliary portion  12 . The second light emitting unit  80  emits a light  83  to the auxiliary portion  12  in a second light path L 2  through a second dripping path D 2  along which the injection drips from the inner chamber  10  of the main portion  11  to the liquid storage space  13  of the auxiliary portion  12 . The second light receiving unit  81  is disposed on another side of the auxiliary portion  12 . 
     As shown in  FIG. 6 , when a drip  9 ′ of the injection  2000  on the second dripping path D 2  does not interrupt the light  83  in the second light path L 2 , the light  83  is not refracted by the drip  9 ′, and the light  83  passes in the second light path L 2 , such that the second light receiving unit  81  receives the light  83  emitted from the second light emitting unit  80  and generates a third light strength signal accordingly. As shown in  FIG. 7 , when the drip  9 ′ of the injection  2000  on the second dripping path D 2  interrupts the light  83  in the second light path L 2 , the light  83  is refracted away from the second light path L 2  by the drip  9 ′, such that the second light receiving unit  81  does not receive the light  83  emitted from the second light emitting unit  80  and generates a fourth light strength signal accordingly. 
     Similarly, the second detecting module  8  is coupled to the control unit F, such that the control unit F processes the third light strength signal and/or the fourth light strength signal for rendering counts of the drip  9 ′. For example, the control unit F renders one count of the drip  9 ′ according to the third light strength signal or the fourth light strength signal received. Alternatively, the control unit F renders one count of the drip  9 ′ as well according to a combination of the third light strength signal and the fourth light strength signal. In other words, the third light strength signal, the fourth light strength signal or a combination thereof is rendered one count of the drip  9 ′ of the injection  2000  on the second dripping path D 2 . 
     In summary, drip rate of the infusion set  1000  can be controlled by the adjustment device C in a manner of rotation of the rotating button  61 , rotation of the rotating cam  61 ′ or stretching of the cylinder head  611 ″. Further, the infusion set  1000  includes detecting modules, such as the first detecting module  7  for detecting the counts of the drip  9  into the main portion  11  of the syringe body  1  and/or the counts of the drip  9 ′ into the auxiliary portion  12  of the syringe body  1 , and the control unit F coupled to the activating module E and the first detecting module  7  and/or the second detecting module  8 . In such a manner, the control unit F of the system  9000  is able to control the activating module E to activate the activating module E to drive the adjustment device C in a manner of rotation of the rotating button  61 , rotation of the rotating cam  61 ′ or stretching of the cylinder head  611 ″ based on the counts of the drip  9  into the main portion  11  of the syringe body  1  and/or the counts of the drip  9 ′ into the auxiliary portion  12  of the syringe body  1 .

FIG.  9  is a diagram illustrating part of the infusion device  1001 ′ in an interrupting state according to the third embodiment of the present disclosure. The major difference between the infusion device  1001 ′ and the infusion device  1001  is that a first detecting module  7 ′ further includes a first auxiliary light receiving unit  72 , and the first auxiliary light receiving unit  72  is disposed aside the first light receiving unit  71 . 
     Please refer to  FIG. 10  as well.  FIG. 10  is a diagram illustrating a first processing signal set A generated by the first detecting module  7 ′ and a second processing signal set B generated by the first auxiliary light receiving unit  72  according to the third embodiment of the present disclosure. As shown in  FIG. 8  and  FIG. 10 , when a drip  9  of the injection  2000  on a first dripping path D 1  does not interrupt a light  73  in a first light path L 1 , the light  73  is not refracted by the drip  9 , and the light  73  passes in the first light path L 1 , such that the first light receiving unit  71  receives the light  73  emitted from the first light emitting unit  70  and generates a first light strength signal a 1 , accordingly. In the meanwhile, the first auxiliary light receiving unit  72  does not receive the light  73  and generates a second auxiliary light strength signal b 2 , accordingly. 
     As shown in  FIG. 9  and  FIG. 10 , when the drip  9  of the injection  2000  on the first dripping path D 1  interrupts the light  73  in the first light path L 1 , the light  73  is refracted away from the first light path L 1  by the drip  9 , such that the first light receiving unit  71  does not receive the light  73  emitted from the first light emitting unit  70  and generates a second light strength signal a 2 , accordingly. In the meanwhile, the first auxiliary light receiving unit  72  receives the light  73  refracted by the drip  9  and generates a first auxiliary light strength signal b 1 , accordingly. 
     Furthermore, the first detecting module  7 ′ is coupled to the control unit F, such that the control unit F processes the first processing signal set A and the second processing signal set B for rendering counts of the drip  9 . For example, a coincidence of the second light strength signal a 2  of the first processing signal set A and the first auxiliary light strength signal b 1  of the second processing signal set B is rendered one count of the drip  9  of the injection  2000  on the first dripping path D 1 .

The major difference between the infusion device  1001 ′ and the infusion device  1001  is that a second detecting module  8 ′ further includes a second auxiliary light receiving unit  82 , and the second auxiliary light receiving unit  82  is disposed aside the second light receiving unit  81 . 
     As shown in  FIG. 12 , when a drip  9 ′ of the injection  2000  on a second dripping path D 2  does not interrupt a light  83  in a second light path L 2 , the light  83  is not refracted by the drip  9 ′, and the light  83  passes in the second light path L 2 , such that the second light receiving unit  81  receives the light  83  emitted from the second light emitting unit  80  and generates a third light strength signal, accordingly. In the meanwhile, the second auxiliary light receiving unit  82  does not receive the light  83  and generates a fourth auxiliary light strength signal, accordingly. 
     As shown in  FIG. 13 , when the drip  9 ′ of the injection  2000  on the second dripping path D 2  interrupts the light  83  in the second light path L 2 , the light  83  is refracted away from the second light path L 2  by the drip  9 ′, such that the second light receiving unit  81  does not receive the light  83  emitted from the second light emitting unit  80  and generates a fourth light strength signal, accordingly. In the meanwhile, the second auxiliary light receiving unit  82  receives the light  83  refracted by the drip  9 ′ and generates a third auxiliary light strength signal, accordingly. 
     Furthermore, the second detecting module  8 ′ is coupled to the control unit F, such that the control unit F processes a third processing signal set including the third light strength signal and the fourth light strength signal and a second processing signal set for rendering counts of the drip  9 ′. For example, a coincidence of the fourth light strength signal of the third processing signal set and the second auxiliary light strength signal of the fourth processing signal set is rendered one count of the drip  9 ′ of the injection  2000  on the second dripping path D 2 . 
     Furthermore, referring to  FIG. 14 ,  FIG. 14  is a second plot of angle versus count per period of time DW 2  according to the fourth embodiment of the present disclosure. As mentioned above, the present disclosure utilizes the adjustment device C to control drip rate of the infusion  2000 , and the present disclosure further utilizes the second detecting module  8 ′ to monitor the counts of the drip  9 ′ of the injection  2000  on the second dripping path D 2 . As a result, it is able to construct the plot which is as shown in  FIG. 14  and illustrates the angle by which the movement member Cl rotates versus the counts of the drip  9 ′ of the injection  2000  on the second dripping path D 2 , so as to provide the staff in hospital with further information when controlling the drip rate of the infusion device  1001 ″ of the infusion set  1000  through operation of the control unit F. 
     Compared to the prior art, the infusion set of the system for detecting and controlling drip rate of the infusion device of the disclosure includes the activating unit which is coupled to the movable member of the adjustment device and drives the movable member to move relative to the base, so as to deform the wall of the at least one of the upper infusion tube, the lower infusion tube and the air tube in cooperation with the base. In such a manner, the drip rate of the injection is able to be automatically adjusted by the activating module. 
     Those skilled in the art will readily observe that numerous modifications and alterations of the device and method may be made while retaining the teachings of the invention. Accordingly, the above disclosure should be construed as limited only by the metes and bounds of the appended claims.
