Abstract
According to the disclosed scheme, the communicating vessel comprises a device body, a first inlet and outlet and a second inlet and outlet are formed in the device body, a cavity is formed in the device body, and the cavity is communicated with the first inlet and outlet; at least three sealing valve leaflets with the same structure are arranged in the cavity; liquid enters the cavity through the first inlet and outlet and then applies pressure to the sealing valve leaflets, the sealing valve leaflets are squeezed towards the central axis of the cavity to close the channel in an attached mode, and sealing between the cavity and the second inlet and outlet is achieved. In the closed state of the channel, the rod-shaped instrument stretches into the channel through the second inlet and outlet and penetrates through the channel and the first inlet and outlet, the sealing valve leaflets are attached to the rod-shaped instrument, and the channel is still closed. The device provided by the utility model is particularly suitable for sealing the inferior cavity or femoral artery and the like of a heart model surgical instrument in the simulation operation process of the preoperative surgery of the structural heart disease.
