Abstract
The utility model relates to the technical field of medical instruments and especially relates to a safety multifunctional injection-feeding interface. The safety multifunctional injection-feeding interface includes an interface substrate connected with an interface sleeve. An elastic rubber plug is pressed between the interface substrate and the interface sleeve. The bottom of the elastic rubber plug is provided with a bottom hole communicated with the interface substrate. A side face of the elastic rubber plug is provided with a side hole communicated with the bottom hole. A gap allowing injection to flow is left between the elastic rubber plug and the interface sleeve. The elastic rubber plug abuts against an injection feeding port in a sealing manner. The injection feeding port can be connected with an infusion set, an infusion bottle or an infusion bag directly. When feeding infusion, an injector is utilized for pushing the elastic rubber plug away from the infusion feeding port and then the infusion flows into an infusion set drip chamber, the infusion bottle or the infusion bag. Normal transfusion can be realized only by screwing the injection feeding interface on the infusion bag or the infusion bottle directly. No entry needles or piercers are needed in the transfusion process and the infusion adding process and risks caused by entry needles and piercers are reduced. Therefore, safety and reliability are improved.
