Retaining needle with multiway channel

The utility model relates to a retained needle with multiway channels, which belongs to the technical field of medical equipment. In the medical care work, a large quantity of liquid sometimes needs to be transfused rapidly and the intravenous injection of medicine is required discontinuously. Because a retained needle for arteries and veins is only provided with one transfusion pipe, a needle pipe can be inserted and pulled out repeatedly to easily cause contamination and haemorrhage and the operating efficiency is low. The utility model is characterized in that a side branch pipe 1 is connected and communicated with the retained needle for arteries and veins 2, and is also connected and communicated with a three-way pipe 3; a positioning sheet 4 is arranged on the retained needle for arteries and veins 2; a switch 5 is arranged on the three-way pipe 3; both end openings of the three-way pipe 3 are sheathed with silica gel sleeve covers 6. The utility model has the advantages that the structural design is reasonable and practical, the three-way pipe is arranged on the retained needle for arteries and veins so that the medicine administration is convenient, the blood transfusion and the transfusion are convenient, the medicine can be administered optionally, the use is simple and convenient, the medical staff's work efficiency can be improved, and the contamination and the haemorrhage in the treating process can be prevented.
