Description
Technical Field
The utility model relates to a medical instrument, in particular to a novel transfusion device.
Background
The infusion solution or large-volume injection solution is large-dose injection solution which is infused into a human body by intravenous drip, and the dose is more than 100ml at one time. It is a branch of injection, usually packaged in glass or plastic infusion bottles or bags, and contains no bacteriostatic agent. When in use, the dropping speed is adjusted by the infusion apparatus, and the medicine is continuously and stably infused into the body. In the prior art, most of the infusion tubes and the medicine bottles of the infusion device are only one needle and one air tube, so that the infusion device is not convenient to puncture and open and close, and therefore, an improved space exists.
