Abstract:
     The cardiac function and body weight index calculating disc is one kind of medical calculating tool and consists of three discs in different diameters and superposed concentrically in the diameter decreasing order from bottom to top. The three discs can be turned around the circular center. When the calculating disc is used, the large disc A or the middle disc B is turned to align the heart rate scale and the age scale of the patient to find out corresponding cardiac function E/A values, including average value, upper limit and lower limit between disc A and disc B; and the middle disc B or the small disc C is turned to align the weight scale and the height scale of the patient to find out corresponding weight index between the disc B and the small disc C.
