Pre-hospital first aid can reduce the mortality and morbidity of critically ill patients, and first aid kit plays an important role in pre-hospital first aid. The first aid kit used in clinic is easy to cause the injection to be broken, and it is inconvenient to use at night. Thus, we have designed an "Owl" first aid kit and obtained a national utility model patent (ZL 2018 2 0727656.7) which includes an injection storage cover and a medicine storage box. A number of injection storage plates are arranged on the injection storage cover, which are used for clamping injections of different sizes, etc., and can effectively prevent injection drugs from being extruded, shedding and broken. There is a supporting rod on one side of the injection storage cover, which can improve the efficiency to take medicine from the first aid kit. There are several partitions in the drug storage box, which can be adjusted according to the size and type of articles placed. A number of symmetrical elastic buckles are arranged on the bottom plate for picking up medicine in bottles, which is convenient for emergency personnel to operate with one hand. There is an illuminating lamp at the edge of the injection storage cover, and a number of fluorescent strips are arranged on the inner wall of the medicine storage box. Based on the above device, it is convenient for medical personnel to pick up medicines at night, which can avoid potential errors effectively. The "Owl" first aid kit has a simple structure and low cost. It can prevent the injection from being broken and convenient to operate. At the same time, it is convenient to be used at night, so it is worthy of clinical application.
