Multi-layer hydrogel forming device

The utility model discloses a multilayer hydrogel forming device. The forming device comprises a confluence device with a plurality of branch runners, connecting ports connected to the upper ends of the branch runners respectively and gel pushing and injecting devices connected to the upper ends of the connecting ports respectively, an adjusting hole is formed in each branch runner in the radial direction, and a flow control bolt is arranged in each adjusting hole. When the device is used, the operation is simple; the preparation method comprises the following steps: firstly, pumping a hydrogel crosslinking precursor solution into a gel injector; then, the gel injector is pushed; the precursor solution is conveyed to the direction of the connecting port and the junction station with a plurality of branch flow channels; through the continuous pushing effect of the gel pushing and injecting device, one-time semi-continuous preparation of the multi-layer hydrogel is achieved, the layer structure is easy to contr
