Abstract

The invention belongs to the technical field of medical instruments, and particularly discloses an automatic infusion device. The automatic infusion device comprises a tube body, a liquid storage cavity formed in the tube body, a liquid outlet exposed out of one end of the tube body and communicated with the liquid storage cavity, and a piston driving assembly for driving liquid in the liquid storage cavity to be fed outwards; and the piston driving assembly is in threaded connection with the tube body and moves back and forth in the length direction of the tube body. According to the automatic infusion device with the structural design, by the threaded connection of the piston driving assembly and the tube body, the piston driving assembly moves in the length direction of the tube body, and then liquid medicine in the liquid storage cavity is pushed out of the liquid outlet so as to complete injection of the liquid medicine. The automatic infusion device is compact in structure and small in volume, can automatically complete injection of the liquid medicine by movement of the piston driving assembly, and is convenient and practical.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to an automatic infusion device. Background technique [0002] In the prior art infusion devices, the driving components used to push the feeding of the liquid medicine are mostly provided separately from the medicine tube, so that the assembled infusion device has a large volume, an insufficiently compact structure, and takes up a large space. Contents of the invention [0003] The object of the present invention is to provide an automatic infusion device, which is compact in structure, small in size and relatively space-saving. [0004] To achieve the above object, the present invention adopts the following technical solutions: [0005] An automatic infusion device, comprising a tube body, a liquid storage cavity arranged in the tube body, a liquid outlet exposed at one end of the tube body and communicating with the liquid storage cavity, and driving the liquid sto...
