A compression device for artificial valve replacing device comprises clamp unit blocks (1). The number of the clamp unit blocks (1) is at least two. The clamp unit blocks (1) are connected with each other in sequence and enclose a crimping channel (2). The compression device further comprises a guide structure (3) for leading all the clamp unit blocks (1) to fold towards the center of the crimping channel (2). When the artificial valve replacing device is placed in the crimping channel (2), the inner wall of the crimping channel (2) props against the peripheral wall of the artificial valve replacing device. When the clamp unit blocks (1) are folded towards the center of the crimping channel (2) under the action of outside force, the inner wall of the crimping channel (2) simultaneously applies the force directing to the central direction of the crimping channel (2) onto the peripheral wall of the artificial valve replacing device. The device has the beneficial effects that the manufacturing cost is low, the cleaning is convenient due to simple structure, and the requirements for operation sanitation during use can be completely satisfied, therefore, the production and maintenance costs are reduced, and the expense shifted to consumers is reduced. |
