Medical care beyond a cold or flu or a minor cut is where my doctors degree ends. Thinking about healthcare or first aid is a must during everyday life and more-so if formal healthcare is not available.
Larger cuts are a real possibility when self reliance is in full play. I found these the other day that would make a great addition to your medical preps.
Your patient will probably be more at ease as well if your not hovering over them with a needle and thread sterilizing the needle with a lighter.
There are other options as well made by 3M corp. All of these are now available over the counter or through Amazon.
These would make a great addition to your mobile medical kit as well as your home medical supplies and could be applied by most any of your team it yourself if required. Beans, Bullets and Zipties.
