Pressure Infusor is a specially designed cuff and bladder device used to pressurize sterile parenteral fluids (not through the alimentary canal, but rather by injection through some other route, as subcutaneous, intramuscular, etc.) to provide for rapid infusion into patients suffering from hypovolemia(diminished volume of circulating blood in the body) and its complications. Generally, parenteral fluids come packaged in flexible bags in either a 500cc or 1000cc size.
The pressure infusor was originally designed to speed the infusion time required to deliver blood. Gravity‐fed blood can typically take up to an hour for delivery to the patient. With the use of the pressure infusor, the blood can be infused in seconds.The IV bag is inserted into the cuff of the pressure infusor; then the bladder is inflated putting pressure on the contents of the IV bag. A valve is used to control the airflow through the bladder. The pressure causes the fluid to be infused more quickly into the patient. Infusion cuffs are inflated with a hand pump similar to that of a blood pressure cuff apparatus. The cuff should be pressurized to 300 mmHg
Two major clinical applications for pressure infusors are:• Rapid infusion of blood, blood products, blood expanders, and IV solutions.• Invasive pressure monitoring proceduresApplications:• Pre-Op & Post-Op Care• Labor & Delivery• Intensive Care• Emergency/Trauma Department• Surgery• Cardiac Catheterization Laboratory
