Detailed Implementation

[0032] The present invention will be further described below with reference to specific embodiments. The accompanying drawings are for illustrative purposes only, representing schematic diagrams rather than actual physical objects, and should not be construed as limiting the scope of this patent. To better illustrate the embodiments of the present invention, some components in the drawings may be omitted, enlarged, or reduced, and do not represent the actual dimensions of the product. It is understandable to those skilled in the art that some well-known structures and their descriptions may be omitted in the drawings.

[0033] like Figures 1-10 As shown, the female urinary incontinence catheterization device mentioned in this utility model can be used for patients with lower limb and spinal fractures and patients with urinary incontinence, reducing pain caused by movement when using a bedpan. It includes a urine collector 1, a urine reservoir 2, and a negative pressure suction device 3. The urine reservoir 2 is connected to the urine collector 1 via a suction tube 5. A negative pressure tube 4 is provided between the negative pressure suction device 3 and the urine reservoir 2. The urine collector 1 consists of an absorbent pad 11, a perforated plate 12, a guide plate 13, and a silicone sleeve 14. The urine reservoir 2 is transparent and has a graduated design, allowing medical personnel to observe urine volume and color at any time. Additional markings can be added if necessary to quickly identify changes in urine color. The negative pressure suction device 3 uses negative pressure control for drainage, effectively reducing urine reflux and leakage. The absorbent pad 11, perforated plate 12, and guide plate 13 are stacked sequentially and housed within a silicone sleeve 14. The perforated plate 12 and guide plate 13 are tightly fitted together, forming a urine collection chamber between them. The urine collection chamber communicates with several sieve holes 127 and is equipped with a suction connector 121 that passes through the silicone sleeve 14 and communicates with the suction tube 5. The absorbent pad 11 is made of a highly absorbent material to provide a comfortable contact surface, effectively absorbing urine and reducing skin irritation. The perforated plate 12 effectively drains urine through the sieve holes 127 while maintaining air circulation, reducing odor and bacterial growth. The guide plate 13 ensures that urine flows smoothly into the urine reservoir and reduces urine retention during the drainage process. The silicone sleeve 14, as the outer covering material of the entire device, must ensure softness to adapt to the body curves of different patients while ensuring a tight seal.

[0034] Specifically, the porous plate 12 is arranged in an arc plate shape, which can better fit the physiological structure of women and improve comfort. The outer arc plate surface is provided with a vertical plate 123 and a special-shaped convex rib 128, and the special-shaped convex rib 128 is provided with a gap 124 away from the vertical plate 123. The vertical plate 123 is provided with a suction hole 122 in communication with a suction connector 121, and the suction connector 121 is arranged on the opposite side of the vertical plate 123 and the special-shaped convex rib 128. The flow guide plate 13 is arranged in an arc plate shape, which is the same as the porous plate 12. The inner arc plate surface of the flow guide plate 13 facing the porous plate 12 is provided with a flow guide fence 134 surrounding the special-shaped convex rib 128 and tightly matching the outer contour of the special-shaped convex rib 128. The inner edge of the flow guide fence 134 of the flow guide plate 13 and the outer edge of the special-shaped convex rib 128 of the porous plate 12 form a sealing clamping structure, and a urine collection chamber is formed between the flow guide plate 13 and the porous plate 12. This sealing structure can effectively prevent urine leakage and ensure smooth flow of urine into the urine collection chamber. The top edge 135 of the flow guide fence 134 is clamped at the gap 124, and one end of the flow guide plate 13 is provided with a flow guide connector 131 connected to the suction hole 122. In this way, the combination of the special-shaped convex rib and the flow guide fence can effectively guide the urine to the urine collection chamber and reduce the retention. The sealing clamping structure helps to prevent urine leakage and improve the safety of use.

[0035] Further, the special-shaped convex rib 128 has a central channel 125 extending along the length direction of the porous plate 12 and a plurality of channels 126 symmetrically arranged on both sides of the central channel 125. The design of the central channel 125 allows the urine to be effectively drained along the length direction of the porous plate 12, and the design of the plurality of channels 126 helps to evenly distribute the urine flow and avoid blockage or retention caused by uneven flow. The plurality of channels 126 are arranged to correspond to a plurality of sieve holes 127 respectively, which can ensure that the urine can flow through multiple paths when flowing into the urine collector, thereby effectively increasing the flow of urine and reducing the flow resistance, thereby improving the drainage efficiency of the whole system. The central channel 125 is aligned with the suction hole 122 to ensure that the urine can flow quickly and smoothly to the urine collector. In this way, the design of the central channel and the plurality of channels can significantly improve the drainage efficiency of the urine and reduce the risk of blockage. Through reasonable channel layout, urine reflux can be effectively prevented, and the risk of urinary tract infection can be reduced. Through the symmetrically arranged plurality of channels, more stable urine flow can be achieved, and discomfort caused by excessive or slow flow rate can be avoided.

[0036] Further, the plurality of holes 127 are arranged in two symmetrical rows, which can ensure the uniformity of urine flow, avoid blockage or discomfort caused by uneven flow; the symmetrical design also helps to ensure the stability of the urine during collection, reducing the flow caused by bubbles or pressure changes; and the hole diameter is gradually reduced towards the back of the plate 123, which helps to control the flow rate of urine. In this way, the smoothness and stability of urine flow will make the patient feel more comfortable during use. In addition, the porous plate 12 is provided with a hole 127 at the distal end away from the plate 123 and on the axis of the central channel 125. The resistance to urine flow can be reduced.

[0037] Further, the guide plate 13 is provided with a guide groove 133 protruding outward from its arc plate surface and extending along its length. The guide groove is designed to protrude outward, which can more effectively guide the urine flow to the guide hole and avoid the retention of urine on the guide plate. This design can reduce the flow resistance and improve the flow efficiency of the urine. The groove extending along the length direction helps to disperse the urine flow, so that the urine can be uniformly distributed on the entire length of the guide plate, reducing the risk of local accumulation. The guide groove 133 is provided with a guide hole 132 communicating with the guide connector 131, so that the urine can flow smoothly into the urine collector, ensuring that the urine can be quickly and smoothly removed, reducing the risk of backflow and overflow. In this way, through reasonable flow path design, the risk of guide hole blockage can be effectively reduced, and the flow of urine can be kept smooth.

[0038] Further, the silicone sleeve 14 is designed in a boat shape, which can better fit the physiological structure of women, provide a comfortable wearing experience, and effectively accommodate the internal components (such as the urine absorption pad 11, the porous plate 12 and the guide plate 13). The inner side of the silicone sleeve 14 is provided with an opening 146, so that the urine absorption pad 11, the porous plate 12 and the guide plate 13 can enter the silicone sleeve 14 through the opening 146, which simplifies the assembly process of the device and facilitates the cleaning and replacement of the internal components. The inner cavity is provided with a stop edge 141 for stopping the plate 123, which ensures the stability of the internal components. The stop edge 141 is provided with a through hole 142 for the suction connector 121 to pass through, which maintains the compactness of the device. The inner bottom is provided with a plurality of rows of ribs 144 for supporting the guide plate 13 and arranged at intervals along the length direction. The ribs 144 are provided with a bayonet 145 for clamping the guide groove 133, which not only provides support for the guide plate 13, but also clamps the guide groove 133 through the bayonet 145, enhancing the stability of the structure and preventing displacement of the components during use. A step 143 is provided around the inner cavity side wall for resting the urine absorption pad 11, which provides additional support and ensures stability during use, reducing the inconvenience caused by movement or displacement.
