| 摘要 |
The present invention relates to a CPR practice apparatus which comprises a pressure part, a support part, and a closed bellows pipe with a built-in spring which can be combined between the pressure part and the support part, so as to remarkably minimize the size of a conventional CPR practice device and to improve storage capacity and transportability. Also, the CPR practice apparatus can adjust the pressure according to adults or children using an intake/exhaust hole formed in connection with the internal space of the bellows pipe and an intake/exhaust device at the support part. In addition, the CPR practice apparatus has protrusions arranged on the inner wall of the pressure part and on the outer wall of the support part, wherein the protrusions can be mutually engaged. Thus, when the CPR practice apparatus is not in use, the volume of the bellows pipe can be minimized and fixated by combining the pressure part and the support part so as to allow a user to usefully store or carry the apparatus. |
