Fascinating…thanks a bunch for this amazingly detailed explanation!! Very elegant but complex design with a lot of safety features. I prescribe this medication and asked my patient to bring a used one so I could dissemble it and then found your video! The ozempic pen ( made by same company) is a 4-dose pak so needle is attached for each administration and dose is dialed every time.
It's very cool. I'm a retired technician, mechanical and electronics. I was happy to find your video. I'm taking this drug. I really enjoyed your explanation. I wonder what your background is. 😋
My professional background is in software engineering. Otherwise I'm just a nerd who's interested in how things work and endlessly curious about the world.
TLDR: The Wegovy injector pen has a complex design with multiple safety mechanisms to prevent accidental pushing, re-injection, and needle exposure, making it a safe and effective tool for administering medication. 00:00 🔍 The injector pen is disassembled to show the parts inside and how they work, including the needle, vial, and assembly process. 01:57 🔧 The injector pen is designed to stay together and has a spring to prevent accidental pushing, with a complex back end cap. 03:11 🔍 The Wegovy injector pen uses a multi-part mold with flexible tabs, arms, a syringe plunger, a long spring, and a steel pin for axial stability, all housed within a sleeve with slots and a channel, with the end cap locking in a restricted rotation. 05:06 🖊 The Wegovy injector pen works by rotating and assembling it to engage with the plunger, using tabs and arms that flex outward when the outer sleeve is in the right position. 07:37 🖊 Assemble, prime, and use a sleeve for the Wegovy injector pen, with a gray piece activating flexible arms and bosses to rotate against the skin. 09:46 🖋 The Wegovy injector pen has a design that prevents re-injection and needle exposure, with a metal strip as a safety mechanism. 11:58 🖊 The Wegovy injector pen has a mechanism to prevent jamming and the plunger from being pushed back in after activation. 14:39 🔧 The injector pen works by keeping the spring loaded, using a guide sleeve for the syringe, and engaging with bosses to prevent the plunger from coming out.
YAH. im not into reusing the pen im just wrecking my brain on how it all worked....and WOW....how would anyone think of this?!!??! LOL its amazing yet so simple!
I watched this video because I'm worried that a nurse could have damaged my 2.4mg pen. It was my first time taking Wegovy and she was only supposed to twist it 8 clicks so I'd receive a 0.25mg dose but she twisted it all the way to the end and back twice as if it was a toy:( So I took it back from her and went to my doctor. Do you know if that could have damaged the pen or is that something safe to do within the mechanisms of the pen? Thanks for your time.
I'm definitely not a medical professional so I can't really answer. If you took it to your doctor, I'd trust that they would know far better than me. But also, the pen in the video is a single use/dose pen. I've seen the use of the Ozempic pens that have a "turn to select dose" feature but haven't taken one apart.

I had access to one of the dial-a-dose Ozempic pens, but never saved one from the trash to see how it worked before it was switched to Wegovy.
