Description

Technical Field

[0001] The utility model belongs to the technical field of medical infusion tubes, and more specifically relates to a double-tube infusion tube. Background Art

[0002] Currently, most infusion tubes are single tubes that can only be connected to one infusion bag at a time, but most patients generally have two infusion bags, that is, medical staff need to replace the infusion bag during the infusion. When there are many people receiving infusion in the infusion room, the operation of replacing the infusion bag will greatly increase the workload of the medical staff in the infusion room, and when the needle on the infusion tube is pulled out and exposed to the air, and then inserted into a new infusion bag, it will cause contamination of the medicine in the new infusion bag. Utility Model Content

[0003] In view of the deficiencies in the prior art, the utility model provides a double-tube infusion tube, which can connect two infusion bags at the same time, greatly reducing the workload of medical staff in replacing infusion bags, while avoiding liquid medicine contamination caused by repeated insertion and removal of the needle on the infusion tube.

[0004] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a double-tube infusion tube, comprising a main tube and two auxiliary tubes connected to the main tube, and the two auxiliary tubes are connected to the main tube, a connecting piece is arranged between the two auxiliary tubes, and the connecting piece is integrated with the two auxiliary tubes, a dividing block is arranged on the two auxiliary tubes, the two auxiliary tubes and the connecting piece pass through the cavity on the dividing block, a dividing blade is arranged in the cavity, and a blocking mechanism is arranged on the two auxiliary tubes, through which only one auxiliary tube can be connected to the main tube.

[0005] Furthermore, the blocking mechanism includes a fixed block, the two auxiliary pipes pass through the fixed block, the two ends of the fixed block are respectively hinged with a blocking block and a supporting block corresponding to the blocking block, the auxiliary pipe is located between the blocking block and the supporting block, and a fixing mechanism is provided on the fixed block.

[0006] Furthermore, the fixing mechanism includes a rotating shaft, which passes through the support block and the connecting plate, and is rotatably connected to the support. Both ends of the rotating shaft extend out of the fixing block, wherein a fan-shaped fixing plate is provided on one end close to the blocking block, and a knob is provided on the other end.

[0007] Furthermore, grooves are provided on both sides of the midline of the connecting piece.

[0008] Furthermore, a pressure strip with a triangular cross section is provided on the blocking block.

[0009] Compared with the prior art, the beneficial effects of the utility model are as follows: the two auxiliary tubes are separated to a certain distance by the dividing block, and the two auxiliary tubes are respectively connected to two infusion bags, and the main tube is connected to the patient. The rotating knob drives the fan-shaped fixed plate to rotate, and first one of the blocking blocks connects the corresponding auxiliary tube, so that the medicine liquid in the auxiliary tube flows to the main tube to realize infusion; when the infusion bag connected to the auxiliary tube that is first connected has finished infusion, the knob is rotated to connect the other auxiliary tube to realize continued infusion. By connecting the two infusion bags at the same time and connecting them in sequence through the blocking mechanism, the workload of medical staff in replacing infusion bags is greatly reduced, and at the same time, the contamination of the medicine liquid caused by repeated insertion and removal of the needle on the infusion tube is avoided.
