[0047] In the embodiment, support piece 10 can be plate structure, etc., not limited here. To facilitate the installation of various components, the opening device can also be provided with fixing frame 70, and fixing frame 70 and support piece 10 can be made of 304, 316L or other stainless steel materials, control component 50 can be installed on fixing frame 70, support piece 10 can be located on the bottom wall of fixing frame 70, support piece 10 can be fixed on the bottom wall of fixing frame 70, or can be set as movable component, can move along at least one direction, so that different use scenarios can be met.

[0048] In the embodiment, the cutting member 20 can be made of 304, 316L or other stainless steel materials, which is not limited herein. The cutting member 20 can also be provided as a movable component, which can be moved in at least one direction, so as to meet the processing requirements of more use scenarios and improve the processing precision and quality of the opening 200a.

[0049] To facilitate replacement and installation of the flexible pressing member 40, preferably, the flexible pressing member 40 can be detachably arranged on the movable component 30. In the embodiment, the flexible pressing member 40 can be a soft rubber structure, which is clamped on the movable component 30 by the clamp 90 or is installed on the movable component 30 by adhesion or clamping and the like.

[0050] It should be noted that the control component 50 can be a manual screw rod, a pressing rod or other manual adjusting components or structures, which is not limited herein. The manual screw rod can be inserted into the lower part from the circular hole at the top end of the fixed frame 70 and is fixed together with the movable component 30 by thread connection or the like.

[0051] It can be understood that the opening device of the medical duckbill valve 200 provided by the utility model improves the compactness of the structure, realizes manual opening of the opening 200a of the duckbill valve 200, reduces the cost, guarantees the precision of the opening 200a, and improves the overall performance and safety of the duckbill valve 200.

[0052] To avoid collision and guarantee the processing precision and quality of the opening 200a, with reference to Figures 7 to 12 In an embodiment, the opening device can further include a limiting component 60, which is arranged on the support component 10 and located at one side of the cutting member 20. The height of the limiting component 60 is less than the height of the cutting member 20, so that the cutting part 21 of the cutting member 20 is cut into the flexible pressing member 40 during cutting.

[0053] In the embodiment, the limiting member 60 can be a limiting cylinder, which can be made of 304, 316L or other stainless steel materials. To meet the processing requirements of openings 200a of different types of products or different specifications of products, the limiting cylinder can be set as a movable component that can move along its axial direction, so as to realize the height adjustment of the limiting cylinder, which is used in cooperation with the cutting member 20. The height of the limiting cylinder is slightly smaller than the total height of the cutting member 20, so that the cutting part 21 is cut into the flexible pressing member 40, thereby cutting the duckbill valve 200 to form the opening 200a.

[0054] To improve the processing efficiency, mainly refer to Figures 7 to 12 In an embodiment, the opening device can further include a reset member 80 arranged between the control component 50 and the fixing frame 70, so as to reset the control component 50 when the external force is removed. In the embodiment, the control component 50 can be a manual or semi-automatic or full-automatic control device or structure such as a screw rod, and the reset member 80 can be a spring or the like, which is not limited herein.

[0055] When the duckbill valve 200 is processed to form the opening 200a, the tool with the cutting member 20 can be taken out first, the prepared duckbill valve 200 is sleeved on the cutting part 21, and the cutting part 21 is attached to the internal groove of the duckbill valve 200, and then the tool is placed on the supporting member 10. The limiting cylinder is placed beside the cutting member 20. Then the manual screw rod is pressed down by hand, and the movable component 30 and the flexible pressing member 40 are driven to move downward by the manual screw rod. Since the cutting member 20 is slightly higher than the limiting cylinder, the cutting member 20 cuts the duckbill valve 200 between the cutting member 20 and the flexible pressing member 40. Since the flexible pressing member 40 is relatively soft compared with the cutting member 20, the cutting part 21 of the cutting member 20 is cut into the flexible pressing member 40, but no damage is caused. This is because the height of the limiting cylinder is slightly lower than the height of the cutting member 20, so the depth of the cutting part 21 of the cutting member 20 cut into the flexible pressing member 40 is small. The flexible pressing member 40 can restore to the original state under the action of its own material properties. After the manual screw rod is pressed to the limiting cylinder, the manual screw rod is moved upward under the action of the reset member 80, so that the flexible pressing member 40 is lifted and restored to the original position. Finally, the opened duckbill valve 200 can be taken out from the cutting member 20 by using tweezers.

[0056] The above description is only optional embodiments of the utility model, and does not limit the patent range of the utility model, and any equivalent structural transformation made under the inventive concept of the utility model, or direct / indirect application in other related technical fields is included in the patent protection range of the utility model.
