Abstract
The utility model discloses a disposable infusion apparatus with a novel structure, which relates to the technical field of medical instruments and comprises a fastening groove arranged below a puncture needle. A fixing seat is arranged at the bottom of the puncture needle, an infusion hose is arranged at the bottom of the fixing seat, a flow regulator is arranged on the infusion hose, an infusion needle is arranged at the other end of the infusion hose, and a blood return prevention device is arranged above the infusion needle. According to the disposable infusion apparatus with the novel structure, the fastening groove is formed, so that when the puncture needle penetrates through the rubber plug in the bottle cap, the rubber plug can be tightly attached to the fastening groove due to the own elastic force of the rubber plug.
