Pharmaceutical Mixer for R&D and newborns
#1
Hey, I came across this idea that sounded cool but I never realised it was necessary in the medical world.

Basically, this small, passive mixer is used to mix and keep medicines in suspension form. The details are here: http://marblar.com/challenge/Micro-mixer/idea/1251

Really, I was curious as to how necessary this is. I mean, once you mix together IV fluids, don't they just stay mixed. Maybe this isn't a great idea for this device?

Hey Dan, your question sounds similar to another comment in the website. Here’s how the author explained it:

First, he believes the passive mixer is especially useful in the NICU department for the drugs administered nasally, since most of these medicines need to stay in suspension when instilled.

When it comes to IV fluids, there are three main advantages of the process:

a) Immediate Mixture. The mixing of drugs can take a while due to the laminar flow. Using the pharmaceutical mixer, the medicines take lesser time in being properly combined.
b) Precise Dosage. Adjusting the flow to precision quantities can assure the right dosage. Thus, reducing dosing errors which are critical to neonates.
c) Less Side Effects on Entry Site. Since the pump can be placed near the penetration site, the drug can be administered in a proper dosage and not coming from upstream. This can also prevent vein blow out since the mixer uses very low pressure.

That said, the device can actually lessen the time needed to mix IV drugs and avoid unwanted dosing issues.
