Merit Medical’s PIB-pressure infusor bag has a dual-pressure safety valve that switches between normal and over-pressure mode with a click of a button. Pressurisation and deflation can be achieved with one hand. The blunt hook will not puncture the fluid bag and is secure in the event of pressure loss. The rigid hanger design slips easily over IV poles. Available in 500mL, 1000mL, and 3000mL sizes. (Not MRI compatible.)
