Description

Technical Field

[0001] This invention relates to the field of urine bag accessory testing technology, specifically a urine bag accessory strength testing load device. Background Technology

[0002] Urine bag accessories refer to various auxiliary components used in conjunction with urine bags to achieve functions such as urine collection, storage, and discharge. As a commonly used medical care product, the strength of its accessories directly affects the safety and reliability during use. In actual use, urine bag accessories may be subjected to various external forces, such as pulling forces generated during patient movement and impact forces during transportation. If the accessories are not strong enough, it may lead to problems such as urine bag detachment or rupture, causing great inconvenience and pain to patients, and may also lead to medical accidents. Therefore, the testing of the urinary catheter in urine bag accessories is particularly important.

[0003] Currently, the strength testing of urine bag accessories mainly relies on manual testing or simple mechanical devices. Manual testing suffers from high subjectivity, inaccurate results, and low efficiency. Existing simple mechanical devices often only simulate tension in a single direction, failing to comprehensively and realistically simulate the complex loads experienced by urine bag accessories in actual use. For example, existing testing devices cannot simultaneously simulate the combined effects of multiple forces, such as vertical gravity, horizontal friction, and tensile forces at different angles. Furthermore, existing testing devices lack precision in load application and control during testing, making it difficult to meet high-precision testing requirements, especially for the cumbersome testing of the catheter within the urine bag accessory.

[0014] Compared with the prior art, the present invention has the following beneficial effects.

[0015] This invention, by setting up a tension adjustment mechanism, is used to extract the urinary catheter in the urine bag accessory that needs to be tested before testing. The catheter is then drawn out in an S-shape and passed sequentially through connecting rods No. 2, No. 3, and No. 4. Connecting rod No. 4 is connected to torsion spring No. 1 via a moving block. When the catheter passes through connecting rod No. 4, it is pressed down, squeezing torsion spring No. 1.

[0016] This invention, by setting up a first strength testing mechanism and a second strength testing mechanism, allows the two strength testing mechanisms to test the strength of the urinary catheter from different angles or using different principles. The first strength testing mechanism can test the compressive strength of the urinary catheter, while the second strength testing mechanism can test the tensile strength of the urinary catheter. This provides a more comprehensive assessment of the strength performance of the urinary catheter, reduces the errors or missed detections that may occur with a single testing mechanism, and thus improves the accuracy and reliability of the test results.

[0017] This invention, by setting up a load adjustment mechanism, allows for the adjustment of the number of load pads to be attached according to the actual strength testing needs, enabling the increase or decrease of the number of load pads for flexible use. It can detect the critical strength value of the urinary catheter and simulate various possible load conditions according to different usage scenarios and requirements, such as resistance during insertion and pulling force generated during patient movement. This allows for more accurate detection of the strength performance of the urinary catheter in actual use, ensuring that it can withstand various external forces during normal use without damage.

[0030] Reference Figure 1 - Figure 8 This invention provides three technical solutions.

[0031] Example 1: A load testing device for the strength of urine bag accessories includes a fixed platform 1 and a mounting frame 2. The mounting frame 2 is fixedly connected to the bottom surface of the fixed platform 1, and a connecting frame plate 3 is fixedly connected to the inner bottom surface of the mounting frame 2.

A tension adjustment mechanism is provided on one side of the fixed platform 1. The tension adjustment mechanism is fixedly connected to one side of the fixed platform 1 through a connecting plate 4. A first strength detection mechanism and a second strength detection mechanism are provided on the upper surface of the fixed platform 1. A load adjustment mechanism is provided on the other side of the fixed platform 1.

[0032] The tension adjustment mechanism includes a fixed column 401 fixedly connected to one end surface of a connecting plate 4. A limit plate 402 is fixedly connected to one side of the outer surface of the fixed column 401. A first connecting rod 405 is fixedly connected inside the limit plate 402. A first rotating shaft 406 is rotatably mounted on the outer surface of the first connecting rod 405. A cylindrical storage box 407 is fixedly connected to the outer surface of the first rotating shaft 406. A locking block 403 is snapped into one side of the upper surface of the fixed column 401. A locking block adjusting bolt 404 is connected to the upper surface of the locking block 403. A vertical plate 408 is fixedly mounted on the other side of the upper surface of the fixed column 401. A plug-in plate 409 is inserted into the upper part of the inner wall of the vertical plate 408. A second connecting rod is rotatably mounted on one end surface of the plug-in plate 409. 410. A first limiting circular plate 412 is fixedly installed at the middle position of the outer surface of the second connecting rod 410. A third connecting rod 413 is rotatably installed on the other side of the outer surface of the plug plate 409. A second limiting circular plate 414 is fixedly installed at the middle position of the outer surface of the third connecting rod 413. A moving groove 415 is opened in the lower part of the inner wall of the vertical plate 408. A moving block 416 is slidably connected to the inner wall of the moving groove 415.

[0033] In this embodiment, the urinary catheter is placed in a cylindrical storage box 407.

A fifth driven wheel 526 is fixedly connected to the other end of the guide roller shaft 516. The outer surfaces of the fifth driven wheel 526 and the first driven wheel 510 are both sleeved with the first belt 508. A second horizontal rod 517 is fixedly connected to the upper part of one side of the outer surface of the first vertical rod 5. A threaded shaft 518 is rotatably installed on one end of the second horizontal rod 517.

[0036] The second strength testing mechanism includes a second vertical rod 519 fixedly installed on the other side of the upper surface of the fixed platform 1. A second top plate 520 is fixedly connected to the upper surface of the second vertical rod 519. A sliding plate 521 is slidably connected to the inner wall of the second vertical rod 519. A third rotating shaft 522 is rotatably mounted on one end surface of the sliding plate 521. An upper limit roller 523 is fixedly connected to the outer surface of the third rotating shaft 522. A fourth driven wheel 524 is fixedly connected to one end surface of the upper limit roller 523. A second belt 525 is fitted on the outer surface of wheel 524. The second belt 525 is fitted with the outer surfaces of the second driven wheel 513 and the third driven wheel 515. A side plate 529 is installed on the lower part of the inner wall of the second vertical rod 519. A lower limit roller 530 is rotatably installed on one end surface of the side plate 529. A second torsion spring 528 is fixedly connected to both sides of the bottom surface of the side plate 529. A base plate 527 is fixedly connected to the bottom end of the second torsion spring 528, and the bottom surface of the base plate 527 is fixedly connected to the upper surface of the fixed platform 1.

[0037] A sleeve rod 532 is fixedly connected to one end surface of the lower limit roller 530, and a fixed cylinder 531 is fixedly connected to one side of the upper surface of the fixed platform 1. The sleeve rod 532 is slidably installed on the outer surface of the fixed cylinder 531. The fixed cylinders 531 are symmetrically distributed on both sides of the upper surface of the fixed platform 1, and the sleeve rods 532 are symmetrically distributed on both ends surface of the lower limit roller 530.

[0038] In this embodiment, after one end of the catheter passes through the middle of the rollers 504 on both sides, the catheter passes sequentially through the upper part of the outer surface of the second rotating shaft 509 and the upper part of the outer surface of the guide roller shaft 516, and exits through the lower part of the outer surface of the connecting frame plate 3. The position of the second crossbar 517 is adjusted, and the distance between the threaded rotating shaft 518 and the guide roller shaft 516 is adjusted so that this distance is less than the diameter of the catheter in its normal state, thereby compressing the catheter and testing its compressive strength. When the catheter passes through the lower part of the outer surface of the upper limit roller 523, the outer surface of the catheter simultaneously contacts the upper part of the outer surface of the lower limit roller 530. One end of the catheter that exits the upper limit roller 523 is inserted into the locking hole 612 and locked. Under the load on one side, the catheter is stretched at the upper part of the outer surface of the lower limit roller 530 and the lower part of the outer surface of the upper limit roller 523, thereby testing its compressive strength. The tensile strength is measured. During formal testing and operation, the power supply of the drive motor 505 is turned on. The output end of the drive motor 505 drives the transmission shaft 506 to rotate, which in turn drives the drive wheel 507 and the first belt 508 to rotate. The rotation of the first belt 508 drives the first driven wheel 510 and the fifth driven wheel 526 to rotate. The rotation of the first driven wheel 510 drives the second rotating shaft 509 to rotate, which in turn drives the second driven wheel 513 on the other side to rotate. The rotation of the fifth driven wheel 526 drives the guide roller shaft 516 and the third driven wheel 515 on the other side to rotate. This causes the second belt 525, which is sleeved on the outer surface of the second driven wheel 513 and the third driven wheel 515, to rotate. The rotation of the second belt 525 drives the fourth driven wheel 524 to rotate, which causes the third rotating shaft 522 and the upper limit roller 523 to rotate, thereby migrating the urinary catheter being tested and enabling continuous testing.

When the output end of the cylinder 604 pushes the telescopic column 605 to move, the telescopic column 605 can drive the pull rope 608 to move, causing the load connecting plate 609 suspended on the bottom surface of the pull rope 608 to descend, so that the load plate 621 is located below the side baffle 102. The upper protective cover 616 and the lower protective cover 617 are removed, and the bevel gear 619 is rotated. The rotation of the bevel gear 619 drives the gear disk 618 to rotate, so that the load plate 621 sleeved on the outer surface of the connecting rod 613 and the hanging rod 614 can be rotated and disassembled. The number of load plates 621 can be adjusted according to the needs of use to configure the corresponding load.
