A medical instrument includes a case formed with a receiving space, a motor mounted in the case as a driving source which is driven by a battery, a power transmission element for converting a rotational motion of the motor to a linear motion, a pressure element connected to the power transmission element for inhaling and discharging ambient air so as to generate a suction force or discharging force of a predetermined pressure, a suction/discharge element integrally coupled with the pressure element and having an inlet for allowing an air to be inspired into the pressure element and an outlet for allowing the inspired air to be discharged from the pressure element to the outside, a power switch mounted an external surface of the case for controlling operations of the motor. Moreover, either of device or an injection device is detachably mounted to the main body of the medical instrument in communication with the inlet or the outlet of the suction/discharge element. <IMAGE> <IMAGE> |
