A sound guiding pipe  419  connects with the hollow part  418  for transmitting sound wave sent with the diaphragm  417  and extends outward the bottom plate  41  as shown in  FIG. 10 . The pull plates  46 ,  47  are mounted between the bottom plate  41  and the cover plate  42  and are in a state of unused state due to elastic forces of the springs  48 ,  49  and the spiral springs  61 ,  62  as shown in  FIGS. 6 and 7 . While in use, the pull plates  46 ,  47  are pulled outward and both lateral sides of the chest part of the patient can be bound by the pull plates  46 ,  47  rapidly due to the elastic forces of the springs  48 ,  49  and the spiral springs  61 ,  62  as shown in  FIG. 11 . The sucking discs can be arranged to place at press spots of the notch between the rib bones and the chest bones with the aid of observing through the peephole  233  of the third cylindrical member  23 . 
   Referring to  FIG. 11 , the fixing plate  13  is attached with a bubble lever gage  133  and a sleeve  71  at the upper side thereof and the sleeve  71  receives a high-pressure oxygen vessel  72 . The high-pressure vessel  72  has a switching push button  721  and connects with an end of an air-guiding pipe  722 . Another end of the air-guiding pipe  722  connects with the fourth intake pipe  35 . When the push button  721  is pressed down, the oxygen rushes into the fourth intake pipe  35 . The second discharge pipe  36  connects with an end of a pressing ball  37  and another end of the pressing ball  37  connects with an end of the air passage pipe  9 ′ shown in  FIG. 1 . Another end of the air passage pipe  9 ′ connects with the mouth-nose breather  8 ′ and the mouth-nose breather  8 ′ masks the mouth and nose of the patient. The sound guiding pipe  419  connects with a stethoscope  96  such that the cardiopulmonary resuscitation can be operated. 
   Referring to  FIGS. 6 ,  7 ,  8  and  11 , once the user presses down the hand press lever  11 , the actuating rod  12  can drive the second extendable air pump  26  and the third extendable air pump  27  to extend downward and expand the volumes thereof. At this time, the outside air can open the unidirectional valves  261 ,  271  to enter the second extendable air pump  26  and the third extendable air pump  27  as shown in  FIG. 6 . When the user raises the hand press lever  11 , the actuating rod  12  drives the second extendable air pump  26  and the third extendable air pump  27  to reduce the volumes thereof. Right at the time, the unidirectional valves  261 ,  271  close respectively and the air in the second extendable air pump  26  and the third extendable air pump  27  is compressed to flow toward the first intake pipe  252  and the second intake pipe  254 . The air in the second intake pipe  254  further flows into the first intake pipe  252 . Right at the moment, the air pushes through the unidirectional valve  255  to enter the first extendable air pump  25  and the first extendable air pump  25  extends to compress the compression spring  24 . Meanwhile, the push piece  121  of the actuating rod  12  drives one of the teeth on the gear  32  to move upward shown in  FIG. 8 . The air in the first extendable air pump  26  is incapable of being sent out via the first discharge pipe  253  due to being controlled by the control valve  31 . Hence, every time the hand press lever  11  is pressed down, the sucking disc  5  under the actuating rod  12  presses the pressing spot once and every time the hand press lever  11  is raised, the air can be filled into the first extendable air pump  25 . In case of the patient being pressed five times before the hand press lever  11  is raised, the gear  32  can be driven to rotate a revolution and to turn on the control valve  31  such that the first extendable air pump  25  can be compressed by way of the elastic force of the compression spring  24  and the air in the first extendable air pump  25  can enter the mixing chamber  311  to mix with the oxygen from the fourth intake pipe  35 . Further, the mixed air can be blown into the mouth of the patient via the air passage pipe  9 ′ and the mouth-nose breather  8 ′. 
   It is noted that the third cylindrical member  23  and the parts therein can be omitted and the second cylindrical member  22  can be joined to the binding device  40  directly. But, two extendable air pumps are utilized can obtain greater amount of filled air. 
   The invention can perform a procedure of pressing the pressed spot of the patient consecutive five times and admitting air automatically one time to make operation of the cardiopulmonary resuscitation more successfully and conveniently. 
   The part in mouth-nose breather, which has to contact with the mouth and nose of the patient, can be designed as a disposal part to avoid possible bacteria being infected between the patients. 
   The invention provides advantages such as the hand pressing filling the a great deal of air, a constant pressing force being obtained to press the heart, the sucking disc fixing to the pressed spot fast, breathing of the patient being capable of being checked with the bubble level gage, hart beating of the patient being capable of being checked with the stethoscope, the mixing chamber in the control valve being capable of mixing the oxygen and the air for increasing the content of oxygen in the air and the pressing ball being capable of supplementing oxygen or fresh air after heart restoring beating. 
   Furthermore, functions of the present invention such as the patient being bound conveniently, providing simple structure, being fabricated easily, supplying more air filled, supplying the patient sufficient blowing air are not provided in the preceding cited US patents. 
   While the invention has been described with referencing to a preferred embodiment thereof, it is to be understood that modifications or variations may be easily made without departing from the spirit of this invention, which is defined by the appended claims.
