I often get asked: what is the difference between Hospital Grade pumps and "drug store" pumps?
While there is no set rules about what constitutes a Hospital Grade pump, basically Hospital-grade breast pumps are powerful, multi-user medical devices with strong, durable motors, primarily used in clinical settings or rented for medical necessity, while personal-grade pumps are smaller, more portable single-user devices for everyday convenience.
Hospital Grade (multiple user) pumps are used when the baby cannot establish nor maintain the milk supply.
Personal (single user) pumps are used when baby has established and can maintain the milk supply, you just want to pump once-in-awhile or go back to work.
Hospital-Grade Pumps are built for multiple users with a closed system to prevent contamination. Maximum suction is about 300mmHg, a number Einar Egnell established as strong enough to draw out the milk, but not so strong as to rupture the ni**le skin (ouch!) The rhythm is also different: smoother, more consistent and with a positive pressure phase at the end of the stroke. In the Egnell SMB you can see the action of the piston. In the Medela Symphony, there are two smaller pistons, one for each side, inside the machine, doing the same thing.
This helps to initiate and maintain the milk supply effectively when the baby cannot, like in the case of prematurity, birth defects, or full-term babies having issues latching on etc.
The motor durability is exceptional. Heavy duty for frequent, long-term continuous use over thousands of hours. None are more longer lasting than the SMB. I have pumps I know are 50+ years old, and still work fine. With the Symphony, I have had motors burn out, but after a few years.
They are considered "portable" (without the stand) as they have handles, but generally you place them in one spot to pump.
Hospital Grade pumps work for most (not all) moms.
Personal pumps are designed for single-user only; sharing can risk contamination unless the pump has a fully closed system. While some will max out to the 300mmHg suction strength, they are doing it with a smaller motor and different rhythm. None have pistons, so the rhythm is more a suck/release like the old hand pumps.
The motor and all other moving parts are not durable, but are designed for less frequent occasional use.
Personal pumps are a lot smaller and much more portable though, better for the on-the-go pumping, or transporting to and from work, but only if the baby maintains the supply otherwise.
Personal Grade pumps don't work for everyone and are VERY subjective.
Hope that helps!
