The problem with first aid kits nowadays is that there are so many that are inexpensive but they are not able to give sufficient assistance in cases of emergency. With that being said, it's important that the kit you purchase is complete. But if you do buy a first aid kit that only comes with band aids, tape and some gauze, it is best that you add in some items to make it complete.
Prior to getting your first aid kit, you have to know first what makes a good one. A good primeros auxilios kit usually comes with a diverse and complete supply of first aid items that are necessary for emergencies. Examples of such include sanitizing products, splints, medicine, a first aid guide, bandages and tape and lotions like sunscreen and lip ointment. You can purchase a complete first aid kit online but you can also opt to put together yourself. The disadvantage though of doing things on your own is that the cost will be higher compared to purchasing a pre-assembled kit.
Nonetheless, if you wish to pursue buying and assembling your own kit, make sure that you strategically store it away and built it according to potential emergencies that may present themselves in the immediate area where the survival kit will be kept away.
For wounds or injury, the first priority in the kit are sanitizing such as alcohol pads and antibiotic ointment. It's important that wounds are cleaned first with effective sterilization equipment before they are covered with a bandage. This is to avoid infection, which is a silent attacker in injuries. Infection can worsen the severity of the injury. Make sure that you have sufficient sterilization supplies with you in your first aid kit.

After the injury is cleaned properly, sterile bandages are then applied to prevent it from getting dirty. Covering it up with a bandage can also support it and protect it from further injury. Put in your first aid kit various sizes of bandages because having band aids only will not be enough for injuries. Splints, medical tape and gauze are used for injuries that need support until help can arrive. For finger injuries, a popsicle stick can work well as a finger splint. Medicines must also be added in like Ibuprofen, aspirin and antacid tablets, which are the most common items in a complete kit. Another important thing that you need to have in your first aid kit is a first aid guide, which you can purchase online.
