Replace Inaprovaline with decompression needles, also known as "needle-Ds", that's it, don't change anything else other than its name and its spirit.
Benefits (How this will benefit the server and game as a whole):
It's a very commonly used military medical tool that serves a /similar/ purpose to inaprovaline, I just think it would be a cool addition for when there's time to play with the code. A needle D is used when someone's lung cavity has been punctured and is letting in air; because your lung cavity needs to be a vacuum, you use a needle D to drain someone's lung cavity of air (often used for gun shot wounds).
Details (Description of how you think this would work, the benefits, etc):

Implementation (Optional, if you have an idea how to implement it):
Just change the spirit and the name of the item, easy stuff.
