Description

Technical Field

[0001] This invention relates to the field of urinary catheter bag manufacturing technology, specifically to a sealing test device for producing urinary catheter bags. Background Technology

[0002] In medicine, a urinary catheter is inserted into the bladder through the urethra to drain urine. There are two types of urinary catheterization: indwelling catheterization and intermittent catheterization. During the production and processing of urinary drainage bags, airtightness testing is required to ensure the production quality of the urinary drainage bags. A sealing test device is needed.

[0003] Currently available catheter drainage bag sealing testing devices do not provide adequate clamping for the catheter bags, making them prone to shifting during airtightness testing, which affects the accuracy of the test. Furthermore, the clamping dimensions of the catheter bags are not easily adjustable, causing inconvenience in use. Additionally, the pressure control during sealing pressure testing is not effective enough.

[0004] For example, the sealing detection device for easy positioning in the processing of urinary drainage bags disclosed in Chinese Invention Patent Publication No. CN113176053A includes a base, a detection mechanism and a positioning mechanism. The base has storage cabinets on both sides inside, and a placement frame is provided at the upper end of the base near the edge. A drive motor is installed at the center of the base, and a connecting shaft is connected to the upper end of the drive motor.

[0005] The aforementioned device is complex to operate during the clamping and fixing of the catheter bag. The lack of softening treatment at the contact point with the outer surface of the catheter bag may lead to damage, affecting production efficiency. Furthermore, during sealing tests, the results of pressure changes cannot be visually displayed, resulting in suboptimal testing effectiveness. Additionally, the positioning mechanism connected to the air inlet cannot guarantee a complete seal at the interface with the catheter bag when the device is connected to it. Therefore, any air leakage during subsequent sealing tests will lead to sealing test results that do not reflect the actual product quality.

[0006] To address this issue, we propose a sealing test device for the production of urinary catheter bags. Summary of the Invention

Multiple fans 6 are installed on both sides of the lower part of the outer surface of the workbench 1. A fixing frame 601 is fixedly connected to the lower part of the outer surface of the workbench 1. A dustproof mesh plate 602 is snapped onto the inner wall of frame 601; the testing mechanism includes a lamp holder 401 fixedly connected to the bottom surface of top plate 101, a lighting lamp 402 fixedly connected to the bottom surface of lamp holder 401, a sealing door 403 installed on the front of test chamber 4, a sealing strip 404 fixedly connected at the contact position between sealing door 403 and test chamber 4, and an observation window 405 fixedly installed in the middle of the front of sealing door 403; the observation window 405 is made of high-strength explosion-proof glass, the sealing strip 404 is made of double-layer silicone material, and the test chamber 4 is made of transparent acrylic sheet material.The moving unit includes a drive motor 408 fixedly mounted on the bottom surface of the partition 102. The output end of the drive motor 408 is connected to a transmission shaft 409. A gear 410 is fixedly connected to the upper part of the outer surface of the transmission shaft 409. A fixed plate 406 is fixedly connected to the bottom surface of the test chamber 4. Slide rails 414 are fixedly connected to both sides of the upper surface of the fixed plate 406. A moving block 415 is slidably connected to the outer surface of the slide rails 414. A connecting column 416 is fixedly mounted on the upper surface of the moving block 415. A vertical plate 417 is fixedly mounted at the middle position of the upper surface of the connecting column 416. A connecting disc 418 is fixedly connected to the upper part of one end surface of the vertical plate 417. A concave block 411 is fixedly mounted on the upper surface of the fixed plate 406. A rack 412 is slidably connected to the inner wall of the concave block 411, meshing with the gear 410. A connecting block 413 is fixedly connected to one end surface of the rack 412, and the connecting block 413 is fixedly connected to one end surface of the connecting column 416.

[0036] In this embodiment, the power supply of the drive motor 408 is turned on, and the output end of the drive motor 408 drives the transmission shaft 409 to rotate, thereby driving the gear 410 to rotate. Through meshing, the gear 410 drives the rack 412 to move when it rotates. By driving the rack 412 to move, the connecting block 413 and the connecting column 416 are moved. The connecting column 416 then drives the moving block 415 to slide on the outer surface of the slide rail 414. The connecting columns 416 moving towards each other on both sides drive the snap-fit ​​member 419 to move.

[0037] Example 2, based on Example 1: The adaptable docking unit includes a snap-fit ​​member 419 disposed on one end surface of the connecting disc 418. The snap-fit ​​member 419 is provided with a plurality of sliding blocks 422. The sliding blocks 422 are fixedly connected to the snap-fit ​​member 419. A first sliding rod 423 is fixedly connected to the outer surface of each sliding block 422. A protrusion 424 is welded to the outer surface of each first sliding rod 423. The first sliding rod 423 is slidably connected to a docking block 425 through the protrusion 424. A connecting column 426 is fixedly connected to one side of the docking block 425, and a docking block 427 is fixedly connected to the other end of the connecting column 426. An air inlet 434 is passed through the middle of one end surface of the sliding block 422. The air inlet 434 passes through the connecting disc 418 and the upright plate 417. An air guide pipe 420 is fixedly connected to the inner wall of the air inlet 434. A pump 421 is fixedly connected to one end of the air guide pipe 420. A vent hole 428 is provided on the connecting column 426, and a sleeve 429 is fitted on the outer surface of the connecting column 426.

A connecting spring 433 is fixedly connected between the second sliding rod 431 and the first sliding rod 423. By setting the sleeve 429 to connect the vent hole 428, the air pressure leakage during the inflation of the urinary catheter bag can be avoided. Excess air pressure can enter the interior of the annular airbag 430, causing the annular airbag 430 to inflate. Thanks to the annular structure design of the annular airbag 430, the contact area with the inflation of the urinary catheter bag can be sealed and filled, effectively preventing air leakage during the inflation of the urinary catheter bag.

[0038] In this embodiment, one end of the sliding block 422 is adapted to mate with the placed urinary catheter bag, and the inflation port 434 inflates the inside of the urinary catheter bag. The pump 421 is operated to pump air into the urinary catheter bag through the air duct 420. During the inflation process, excess air pressure enters the annular air bladder 430, causing the annular air bladder 430 to expand and seal the contact position between the urinary catheter bag and one end of the sliding block 422, thus preventing air leakage of the urinary catheter bag during the sealing test.

[0039] In practical applications, there are single-port, single-channel catheter bags. Therefore, the single-sided inflation port 434 in this application completes the docking, and the annular airbag 430 achieves the abutment and fixation, without the need for external fixing parts or manual control.

[0040] Example 3, based on Examples 1 and 2: The pressure regulating mechanism includes a mounting base 5 fixedly installed on one side of the inner bottom surface of the workbench 1. An oil-free air compressor 501 is fixedly installed on the upper surface of the mounting base 5. The output end of the oil-free air compressor 501 is fixedly connected to a connecting pipe 502. One end of the connecting pipe 502 is fixedly connected to a first pressure regulating valve 504.

A connecting pipe 517 is fixedly connected to the output end of the air filter 516. Pressure sensor 518 is fixedly connected to the outer surface of connecting pipe 517.

A pressure sensor 520 is fixedly connected to the top surface. A pressure regulating mechanism is set up, consisting of two pressure regulating valves, two one-way valves, and an air filter 516. Both pressure regulating valves are high-precision digital pressure regulating valves with a pressure regulating accuracy of ±0.01MPa. The air filter 516 can effectively remove impurities and moisture from the air, ensuring that the air entering the test chamber 4 is pure and dry, thus avoiding contamination of the catheter bag. Pressure sensors 514 and 518 are connected to the outer surfaces of the sixth connecting pipe 513 and the seventh connecting pipe 517, respectively, which can monitor the air pressure value of each section in real time and facilitate adjustment.

[0041] In this embodiment, the oil-free air compressor 501 is operated, and the output end of the oil-free air compressor 501 outputs air pressure. The air pressure enters the connecting pipe 502. The first pressure regulating valve 504 or the second pressure regulating valve 508 is selected to avoid the inability to use the air if one of the pressure regulating valves fails. The regulated air pressure enters the one-way valve and then enters the sixth connecting pipe 513. The first pressure sensor 514 detects the air pressure in the sixth connecting pipe 513 in real time. The air pressure enters the air filter 516 to filter and remove impurities and moisture from the air. The air pressure passing through the air filter 516 enters the seventh connecting pipe 517. The second pressure sensor 518 monitors the air pressure in the seventh connecting pipe 517 in real time. The seventh connecting pipe 517 inputs the air pressure into the test chamber 4 to perform a pressure test on the urinary catheter bag. The pressure is monitored in real time by multiple third pressure sensors 520 installed on the upper and lower sides of the test chamber 4.
