The pressure apparatus is composed of shell with the first and second chambers, a pressure chamber storing the compressed gas, an adjustor between the pressure chamber and the second chamber, and a pressure indicator showing the pressure of the second chamber. The said compressed gas is exported to the adjustor and by adjusting the adjustor, the pressure within the second chamber reaches the set point and presses on the bag to inject the drug into the body. So, the apparatus is used for injection the drug by the pressure on the intravenous bag.
