Description

Technical Field

[0001] The present invention relates to the technical field of medical instruments, and more particularly to a portable emergency medicine storage and injection device. Background Art

[0002] Currently, injections of some drugs generally require professional medical personnel to perform the injections. However, in the event of an emergency, the absence of medical personnel or the lack of drugs may often lead to missing the best time for treatment, causing damage to the patient's body.

[0003] For example, in special work scenarios such as fire rescue, forest patrol, and address exploration, when workers are injured and need first aid medication, they often encounter problems such as insufficient emergency rescue drugs due to the inconvenience of carrying the medicine box, and a lack of professionals to undertake drug injections, causing the injured to miss the best rescue time.

[0004] Therefore, it is an urgent problem for those skilled in the art to develop a portable emergency drug storage and injection device that is easy to carry and easy to complete drug injection. Summary of the Invention
