Description

Technical Field

[0001] This invention relates to the field of urine bag manufacturing technology, and more specifically to a urine bag manufacturing equipment for automatic assembly of urinary catheters. Background Technology

[0002] Disposable medical urine bags are the core consumables of clinical urine drainage systems. They are mainly made of PVC film bags and catheter connectors that are heat-sealed together. Their welding seal and dimensional consistency directly determine the safety and reliability of clinical use.

[0003] Chinese patent CN218399640U discloses a urine bag making machine, including a cabinet, and sequentially mounted on the cabinet an unwinding mechanism, a labeling mechanism, a folding mechanism, a punching mechanism, a heat sealing mechanism, a material transfer mechanism, and a cutting mechanism. The urine bag film raw material roll is unwound by the unwinding mechanism, and the plastic film is labeled by the labeling mechanism. Then, the unwinding mechanism sends each urine bag film to the labeling mechanism for labeling, followed by folding by the folding mechanism, and then punching by the punching mechanism. The two ends of the film are then heat-sealed to form a complete urine bag. Finally, the material transfer mechanism transfers the film to the cutting mechanism for cutting into individual urine bags. However, this device still has the following problems during use: When assembling a urinary catheter, it is still necessary to separate the upper and lower membranes by using an external clamping device after reaching the assembly station. The separated upper membrane lacks limiting constraints and is prone to rebound and wrinkles, making it impossible to stably maintain the layer gap. When the urinary catheter is inserted, it is easy to scrape the membrane and misalign, resulting in defective products.

[0012] The terms "left," "right," "front," "back," "up," and "down" used in the following description refer to the orientation from the perspective of the front view.

[0013] In some embodiments, please refer to the accompanying drawings. Figures 1-11A urine bag production equipment for automatic assembly of urinary catheters includes a base 1, a membrane roll roller 2, an auxiliary film feeding mechanism, an automatic film separating mechanism 5, a multi-station continuous insertion and welding mechanism 6, a follow-up reset detection mechanism 7, and a finished product processing and unloading mechanism. Two film roll rollers 2 for storing PVC film are rotatably mounted on the left side of the front end of the base 1; like Figure 1 and Figure 3 As shown, the base 1 is equipped with multiple traction roller sets for controlling the movement of PVC film; The traction roller assembly adopts mature technologies in the industry; for example, the traction roller assembly in Chinese patent CN206678420U. An auxiliary film feeding mechanism for assisting the intermittent movement of PVC film is connected to the base 1; An automatic film separating mechanism 5, used to automatically separate the upper and lower PVC films for catheter assembly, is connected to the base 1. The automatic film dispensing mechanism 5 includes a dispensing component and a film pressing component; the dispensing component and the film pressing component are connected to the base 1; The multi-station continuous catheter welding mechanism 6, used for inserting a urinary catheter between upper and lower PVC films and performing heat pressing, is connected to the base 1. The multi-station continuous cannulation welding mechanism 6 includes a control box 61, an electric rotary table 62, assembly components, cannulation components, and a hot pressing component; the control box 61 is symmetrically arranged on the front and rear sides of the base 1; the electric rotary table 62 is fixedly installed on the upper end of the control box 61; multiple assembly components are installed in a circumferential array at equal intervals on the movable end of the electric rotary table 62. The pipe-through assembly is installed at the left end of the control box 61; the hot-pressing assembly is connected to the base 1; The outlet of the linear vibrator used for delivering the urinary catheter is aligned with the catheter insertion assembly; The follow-up reset type detection mechanism 7, used to perform airtightness testing on the urine bag after the catheter assembly operation is completed, is connected to the base 1. The follow-up reset type detection mechanism 7 includes an inflation assembly, a sealing assembly, and a flattening assembly; the inflation assembly is symmetrically installed on the front and rear sides of the base 1; the flattening assembly is connected to the base 1; the sealing assembly is symmetrically installed on the front and rear sides of the flattening assembly; The finished product processing and feeding mechanism, which discharges the urine bag based on the airtightness test results, is installed on the right side of the base 1; The finished product processing and unloading mechanism includes a cutting mechanism 8 and a sorting and unloading mechanism 9; both the cutting mechanism 8 and the sorting and unloading mechanism 9 are installed on the right side of the base 1. The sorting and unloading mechanism 9 includes a handling component, a qualified product linear conveyor 98 and an unqualified product linear conveyor 99; the handling component is connected to the base 1; the qualified product linear conveyor 98 and the unqualified product linear conveyor 99 are symmetrically arranged on the rear and front sides of the base 1. In this invention, multiple traction roller groups installed on the base 1 drive two sets of PVC films that are bonded together to move to the right along the base 1. During the movement, the auxiliary film feeding mechanism can compensate for the speed difference between the film roll roller 2 and the traction roller group, continuously maintain the constant tension of the PVC film during the conveying process, avoid the PVC film from being stretched, wrinkled or loosened, and ensure the accuracy of subsequent processing. During the movement, the left side of the material distribution component will separate the upper and lower bonded PVC films, causing the upper PVC film to bend upward and move into the film pressing component, while the lower PVC film will continue to move to the right along the base 1. When the PVC film moves to the right side of the dispensing assembly, the upper and lower PVC films will gradually stick together and restore their original shape. At this time, the electric rotary disk 62 controls the assembly component to rotate, ensuring that the assembly component with the catheter installed moves between the upper and lower PVC films before the upper and lower PVC films are glued and restored. Then, the hot pressing component fixes the upper and lower ends of the catheter from the upper and lower sides and heat-presses the catheter and PVC film to form a urine bag. At the same time, the catheterization assembly installs the next catheter onto the next assembly assembly, ensuring that the device can perform continuous catheter installation thermocompression operations; Subsequently, the traction roller group controls the PVC film, which has completed the hot pressing operation of the catheter, to move to the right until it moves under the flattening component; The compression sealing assembly presses the catheter from above, and then the inflatable assemblies on the front and back sides are inserted into the urine bag along the catheter. The compression sealing assembly then continues to move down to further compress the catheter. The inflation component then inflates the urine bag with gas, and continuously monitors the air pressure inside the urine bag until it reaches the preset value. If the air pressure inside the urine bag does not drop below the air tightness detection threshold within a preset time after the inflation component stops inflating, it indicates that the urine bag meets the air tightness requirements and is judged as a qualified product; otherwise, it indicates that the urine bag has an air tightness problem and is judged as a non-qualified product. After the test is completed, the inflation and sealing components are reset; the flattening component will expel the residual gas in the urine bag to the outside, avoiding the extra workload of manual degassing during subsequent packaging, and further ensuring the stability of the urine bag delivery position. Finally, the cutting mechanism 8 will cut and separate the urine bag after the catheter assembly and airtightness test are completed. Then, the conveying component will adsorb and fix the urine bag on the moving end of the qualified product linear conveyor 98 or the unqualified product linear conveyor 99 according to the airtightness test result for unloading. Then, the qualified product linear conveyor 98 or the unqualified product linear conveyor 99 will drive the urine bag to the next processing step.

In this invention, the traction roller group installed on the base 1 controls the PVC film to move along the first tension roller 31, the pusher roller 32 and the second tension roller 33. During the movement, the floating cylinder slide module 34 will intermittently pull the pusher roller 32 to move up and down back and forth to store or release the PVC film, eliminate the instantaneous speed difference between the film roll roller 2 and the traction roller group, and avoid the PVC film being stretched or loosened in an instant. The pressure cylinder slide module 42 controls the first pressure plate 43 to move down. At this time, the first pressure plate 43 will press the PVC film onto the upper end of the pressure plate 44 to prevent the PVC film from shifting, thereby ensuring the stable operation of catheter assembly or airtightness testing. The material separation assembly includes a first separation limiting plate 51 and a second separation limiting plate 52; both the first separation limiting plate 51 and the second separation limiting plate 52 are fixedly connected to the base 1; the installation position of the second separation limiting plate 52 is higher than that of the first separation limiting plate 51.

A gap with the same thickness as a single PVC sheet is provided between the upper receiving plate 53 and the second pressure plate 55. In this invention, when the upper and lower PVC films are moved to the positions of the first separation limiting plate 51 and the second separation limiting plate 52, the upper PVC film will move from below the first separation limiting plate 51 to the upper end of the second separation limiting plate 52, and move along the upper end of the second separation limiting plate 52 to the gap between the upper receiving plate 53 and the second pressure plate 55. The PVC film below will continue to move to the right along the base 1, thereby completing the automatic separation of the upper and lower PVC films; The assembly components include a rodless cylinder 63, a movable plate 64, a receiving rod 65, and a guide sleeve 66; the rodless cylinder 63 is fixedly mounted on the movable end of the electric rotary disk 62; the movable plate 64 is fixedly connected to the movable end of the rodless cylinder 63; the receiving rod 65 is fixedly connected to the movable plate 64; the guide sleeve 66 is fixedly mounted on the movable end of the electric rotary disk 62; and the receiving rod 65 is slidably connected to the inner wall of the guide sleeve 66.

The lifting cylinder slide module 617 is fixedly installed at one end of the front and rear control boxes 61 that are close to each other; the lower conforming hot pressing block 618 is fixedly connected to the moving end of the lifting cylinder slide module 617. In this invention, during the process of the upper and lower PVC films moving to the right after being separated by the first separation limiting plate 51 and the second separation limiting plate 52, the upper and lower PVC films will gradually stick together and restore their original shape. At this time, the electric rotary disk 62 controls the movement of multiple rodless cylinders 63 and guide sleeves 66 to ensure that the guide sleeve 66 with the catheter installed moves between the upper and lower PVC films before the upper and lower PVC films are bonded and restored, and at this time the catheter is located between the upper and lower PVC films. Subsequently, the front and rear lifting cylinder slide module 617 pushes the lower conforming hot pressing block 618 upward to support the lower end of the catheter; while the upper hot pressing cylinder slide module 615 controls the upper conforming hot pressing block 616 to press down, thereby pressing the upper end of the catheter. Then, the external power supply controls the upper conforming hot pressing block 616 and the lower conforming hot pressing block 618 to heat up, thereby completing the hot pressing operation between the catheter and the PVC film. Subsequently, the rodless cylinder 63 controls the moving plate 64 to drive the receiving rod 65 to move towards the center of the electric rotating disk 62, ensuring that the receiving rod 65 is pulled out of the catheter. At the same time, the linear vibrator will control the next catheter to move into the slot opened on the transition table 68; Subsequently, the material transfer dual-axis push cylinder 610 controls the material transfer clamping cylinder 611 to move down, and then the material transfer clamping cylinder 611 clamps and fixes the catheter in the slot. The material transfer dual-axis push cylinder 610 drives the catheter to move up and align with the next guide sleeve 66. Then the next rodless cylinder 63 controls the receiving rod 65 to move to the left along the guide sleeve 66 and insert into the catheter. Subsequently, the material transfer clamping cylinder 611 releases the clamping and fixing of the catheter. Then, the push cylinder 612 controls the push block 613 to move to the right. During the movement, the push block 613 will push the left end of the catheter to ensure that the catheter is completely moved onto the receiving rod 65, ensuring that the device can perform continuous catheter installation hot pressing operation.

The sealing assembly includes a positioning cylinder 74 and a positioning block 75; the positioning cylinder 74 is fixedly connected to the detection frame 71; the positioning block 75 is fixedly connected to the movable end of the positioning cylinder 74. In this invention, when the urine bag equipped with the catheter moves directly below the exhaust pressure plate 73, the traction roller group stops conveying the PVC film, and then the positioning cylinder 74 controls the positioning block 75 to move down to ensure that the positioning block 75 contacts the upper end of the catheter. Subsequently, the detection cylinder slide module 76 controls the front and rear mounting plates 77 to move in a closer direction. During the movement, the conical cannula 79 will gradually be inserted into the catheter until the outer side of the conical cannula 79 is pressed against the catheter opening. Then, the positioning cylinder 74 controls the positioning block 75 to continue to move down to ensure the sealing between the catheter and the conical cannula 79. Then, the external air pump fills the urine bag with gas through the detection tube 78 and the conical insertion tube 79. The pressure sensor will also continuously monitor the air pressure in the urine bag until the air pressure in the urine bag reaches the preset value. If the air pressure inside the urine bag does not drop below the air tightness detection threshold within a preset time after the external air pump stops inflating, it indicates that the urine bag meets the air tightness requirements and is judged as a qualified product; otherwise, it indicates that the urine bag has an air tightness problem and is judged as a non-qualified product.
