The invention discloses a body cavity blocking device with compact structure, which comprises a guide wire, a catheter and a blocking object that can be compressed along the axial direction, wherein the blocking object is formed by more than two pieces of flat diaphragms, the surfaces of which are coated with hydrophilic coatings, so that the diaphragms are cohered with each other and take on a flat shape; at least one tube cavity which can pass through the guide wire is arranged along the axial direction of the diaphragms; the far ends of the diaphragms are fixed with the guide wire for drawing the near end of the guide wire; and after the unfolded blocking object is compressed along the axial direction, a plug-shaped blocking object is formed along the radial direction. The body cavity blocking device has small structure and simple operation, can more fully block compared with a blocking device formed by a single diaphragm, and can effectively prevent a barrier from escaping from the gap of the blocking dev
