Description

Technical Field

[0001] The invention relates to the field of first aid equipment, and in particular to an emergency treatment device for poisonous snake bites. Background Art

[0002] People are prone to snake bites in or around bushes when outings, camping or mountain climbing. When bitten by a non-venomous snake, there will only be a slight sting without systemic reaction, and 70% alcohol can be used for disinfection, but a bite by a venomous snake can cause severe poisoning and requires emergency treatment.

[0003] First aid for snake bites is to immediately tie up the proximal limbs of the bite site with a bandage on the spot, tighten it to prevent venous blood and lymphatic reflux, then rinse the wound, cut a little in the dermis for deeper wounds (but if the coagulation function is lost, it cannot be cut to drain the poison), then suction to promote the discharge of some venom, and then inject anti-venom serum, etc. In the prior art, multiple tools are used to complete the above first aid treatment, such as tools for rinsing the wound, tools for cutting the wound, and tools for sucking out the venom. These tools are relatively scattered and take up space. When using them, it is easy to be in a hurry and inconvenient to carry them out. Summary of the invention
