Spring Loaded Injector
Description
What's the difference between $20 and $1000? A $3 spring and about 50c worth of plastic - if you live under the US medical system at least. I've designed a spring-loaded injector. You can load the syringe in, cock it, then twist to release causing the syringe to automatically prick you. Then all you have to do is manually push the plunger. The assembly consists of 3 components: * Spring Compressor * Syringe Spacer * Spring [McMaster-Carr 9434K97] My design is specifically for 100ml (10 units of 10ml) syringes typically used for insulin, with a ø7mm x 80mm barrel for subcutaneous use only [NOT FOR INTRAVENOUS USE!]. I have provided STLs and STEP files - feel free to modify the STEP files for your syringe size. If you ask me politely, I may be willing to modify this design for your syringe size too. Many people have to take injections: insulin, hormone replacement, GLP1s, birth control etc. The name brand prescriptions with the nice spring-loaded cartridges often cost upwards of $1000 if you are uninsured or underinsured. However, often cases you can be prescribed a multi-dose vile of the medicine and a package of syringes for $10-100ish. But if you're like me and not good with needles, it can be incredibly difficult to inject yourself. Plus this has the added benefit of being reusable and thus generating less plastic waste than disposable cartridges. I have two spacers, one has a single thread, the other is triple threaded for a multi-start. Note - I have not tested the multi-start. NOTE: This is not intended for commercial purposes whatsoever. If you sell this you are an A-hole. This is not an FDA or otherwise approved product. Use at your own risk. I am not responsible for what you do with this. This is only compatible with subcutaneous use, not for intravenous use (you'll just stab your vein dummy). Feel free to message me with any suggestions
