[0028] In addition, it should also be noted that in the description of the utility model, unless otherwise explicitly specified and limited, the terms "mounting", "connection" and "connection" should be understood broadly, for example, it can be fixedly connected, or it can be detachably connected, or integrally connected; it can be mechanically connected, or it can be electrically connected; it can be directly connected, or it can be indirectly connected through an intermediate medium; it can be the communication between two elements. For those skilled in the art, the specific meaning of the above terms in the utility model can be understood according to the specific circumstances.

[0029] As Figures 1 to 4 shown, the embodiment proposes a urinary stoma bag opening device, which comprises a base 1, a support arm 2 fixed on the right side of the base 1, a fixed table 3 connected to the support arm 2, the fixed table 3 is located on the left side of the support arm 2, and the base 1 and the fixed table 3 have a certain distance through the support arm 2, which is used for punching the stoma bag bottom disc; a vertical through hole 31 is formed in the fixed table 3, and a movable cavity 32 is also formed in the side wall of the fixed table 3 and communicates with the through hole 31; the device further comprises a guide rod 5 and a pressing assembly above the guide rod 5, the guide rod 5 moves vertically in the through hole 31 and the movable cavity 32 through the pressing assembly, a limiting ring 6 is fixed on the outer wall of the guide rod 5, and the limiting ring 6 is located in the movable cavity to prevent the guide rod 5 from falling out; the device further comprises a cutting cylinder 8, which is detachably connected above the guide rod 5, a pressing ring 9 is arranged above the cutting cylinder 8, and not less than two groups of push rods 10 are connected below the pressing ring 9, the push rods 10 freely penetrate the cutting cylinder and are connected with a push ring 11.

[0030] In the punching process, first, the part to be punched of the stoma bag bottom disc is placed on the base 1. According to the required punching size, the corresponding cutting cylinder 8 is selected and installed below the guide rod 5. Then, the guide rod 5 is pressed by the pressing assembly, and the guide rod 5 in turn drives the cutting cylinder 8 below it to perform cutting and punching operation on the stoma bag bottom disc. After the punching is completed, the cutting cylinder 8 is further driven to move downward by pressing the pressing ring 9, so that the part cut in the cutting cylinder 8 is ejected. Compared with the traditional cutting cylinder design, in which the cut part remains in the cutting cylinder 8 and is difficult to take out and is easy to be injured by the sawtooth at the bottom of the cutting cylinder 8 during the taking-out process, the design realizes the automatic ejection of the cut part through the cooperation of the pressing ring 9 and the push ring 11, effectively avoiding the difficulty of manual taking-out and the potential risk of hand injury.

[0031] In some embodiments, the pressing assembly comprises two ear plates 12 fixed on the left side above the fixed table 3, a pressure rod 7 is hinged between the two ear plates 12, and the bottom of the pressure rod 7 has a protruding part 71 for pressing the guide rod 5. In this design, the principle of lever is ingeniously used to realize more labor-saving punching operation. Taking the hinge point of the pressure rod 7 as the fulcrum, the other end of the pressure rod 7 is pressed, and the protruding part 71 applies downward pressure to the guide rod 5, so that the cutting cylinder 8 completely cuts through the stoma bag bottom disc. Not only simplifies the operation process, but also significantly reduces the required force. Through the lever effect, small input force can be converted into large output force, and people with small strength can also easily punch, making the punching process more relaxed and efficient.

[0032] As Figure 3As shown, in some embodiments, the pressing rod 7 comprises a first rod body 72 hinged between the two ear plates 12, a placement slot 73 is formed in the first rod body 72, a second rod body 74 is hinged at the end of the first rod body 72, and a handle 4 is fixedly connected to the end of the second rod body 74. When not in use, the second rod body 74 is folded and placed in the placement slot 73. This design can effectively reduce the occupied space of the pressing rod 7, and also improve the portability and storage efficiency of the device. In addition, the folding structure also enhances the adaptability of the device, making it more flexible and convenient to use in different environments and conditions.

[0033] In some embodiments, a first spring 13 is further sleeved on the outer wall of the guide rod 5, and the first spring 13 is connected below the limiting ring 6. In the original design, the guide rod 5 is in a downward state due to gravity, and the user needs to manually lift the guide rod 5 before punching to place the ostomy bag bottom disc below the cutting cylinder 8. This process is relatively cumbersome and inefficient. To solve this problem, the first spring 13 is connected below the limiting ring 6 in the design. This allows the cutting cylinder 8 below the guide rod 5 to remain in a suspended state, maintaining a certain distance from the base 1. In this way, the user can place the ostomy bag bottom disc directly on the base 1 without manual intervention, simplifying the operation steps and improving work efficiency and convenience.

[0034] Further, a second spring 14 is sleeved on the outer wall of the push rod 10, and the second spring 14 is located between the top surface of the cutting cylinder 8 and the pressing ring 9. The second spring 14 allows the push ring 11 to be located in the upper half area of the cutting cylinder 8. When needed, pressing the pressing ring 9 moves the push ring 11 to the lower half area of the cutting cylinder 8, thereby pushing out the cut ostomy bag bottom disc.

[0035] In some embodiments, the pressing rod 7 is fixedly connected with a pressing disc 15 at the bottom, and the bottom of the pressing disc 15 is connected with a magnetic piece 16 that is magnetically connected with the bottom surface of the cutting cylinder 8, to realize quick disassembly and replacement of the cutting cylinder 8. This design allows the user to select and install different sizes of cutting cylinders 8 according to different needs of the ostomy bag bottom disc, to perform accurate cutting. Further, a circular groove 17 is formed on the top surface of the cutting cylinder 8, and the circular groove 17 is located in the pressing ring 9. The pressing disc 15 can be correspondingly embedded into the circular groove 17. This design can ensure that the cutting cylinder 8 and the guide rod 5 are on the same axis, and the user can easily align and fix the bottom disc with the cutting cylinder 8, which is convenient for subsequent punching process and alignment with the ostomy bag bottom disc, avoiding inaccurate conditions such as skew.

[0036] Optionally, the bottom of the cutting cylinder has an annular cutter or a plurality of groups of annularly arranged sawteeth.

[0037] In some embodiments, a buffer pad 18 is fixedly connected above the base 1, and the buffer pad 18 is located in the area below the cutting cylinder 8. The buffer pad 18 is made of rubber material to avoid wear and tear when the cutting cylinder 8 cuts the ostomy bag bottom disc and contacts the base 1.

[0038] Although the specific embodiments of the utility model have been described in connection with the accompanying drawings, it is not a limitation on the scope of protection of the utility model, various modifications or deformations made by those skilled in the art on the basis of the technical scheme of the utility model without creative labor are still within the protection scope of the utility model.
