Micro-injection pin header and use method thereof

The invention discloses a micro-injection pin header and a using method thereof, and relates to the technical field of medical instruments. The flexible connector can better adapt to the human body curve, and injection pain relieving is achieved; meanwhile, the flexible connector can be fixed on the skin under the action of the sticking sheet, so that the injection pin header can be effectively prevented from integrally shifting; the connector is used for being connected with an external infusion pipeline or an external micro infusion pump, analgesic medicine is input into the hose through the connector, reaches the cavity from the hose and finally reaches the needle head, the analgesic medicine can directly act on tissues and skin around a wound, and the better analgesic effect is achieved. Meanwhile, compared with conventional intravenous injection pain relieving, intramuscular injection pain relieving and oral medicine pain relieving, the pain relieving effect is faster; under the action of the adjusting p
