Description

Technical Field

[0001] This utility model relates to the field of medical device technology, specifically a multifunctional testing device for medical device maintenance. Background Technology

[0002] Medical devices refer to instruments, equipment, appliances, in vitro diagnostic reagents and calibrators, materials, and other similar or related items that are used directly or indirectly on the human body. They have a wide range of uses, covering diagnosis, prevention, treatment, monitoring, or pain relief. For example, ultrasound diagnostic instruments commonly used in hospitals can provide doctors with images of the internal structure of the human body through ultrasound waves to assist in disease diagnosis. Pacemakers are implanted in the human body and stimulate the heart by sending electrical pulses to maintain a normal heartbeat. The safety and effectiveness of medical devices are crucial to medical quality and patient health, and their research, development, production, sales, and use are all subject to strict regulation.

[0003] Traditional medical device testing technologies have shortcomings. On the one hand, their functions are relatively limited, usually only able to test one aspect, making it difficult to meet the complex and diverse maintenance needs of medical devices. Frequent replacement of testing equipment is required when maintaining different types of devices, resulting in low efficiency. On the other hand, the testing process is cumbersome and lacks stability. When adjusting the test position, there is a lack of precise and flexible adjustment mechanisms, making operation inconvenient and difficult to accurately position. The fixing method is simple, and displacement or shaking is prone to occur during testing, affecting the accuracy of test data. To address these issues, we propose a multifunctional testing device for medical device maintenance. Utility Model Content

[0059] Working principle: The core driving component of the testing device is the drive motor 1. When the drive motor 1 starts, its output shaft drives the threaded rod 2, which is fixedly connected to it, to rotate. Since the threaded rod 2 is threadedly engaged with the threaded bushing 3 at the center of the moving bar 4, and the moving bar 4 is slidably sleeved with the guide post 10 fixed inside the test base 9 through the guide holes 22 on both sides, the rotation of the threaded rod 2 causes the moving bar 4 to move linearly along the guide post 10. This movement mechanism allows the pressure detection module 7 or speed detection module 8, mounted on the support frames 5 at both ends of the moving bar 4, to move to the appropriate testing position. The testing device also features… The fixture 12 features flexible position adjustment and fixation. An adjustment strip 13 on the back of the fixture 12 passes through and slides onto the fixing plate 11. Rotating the fixing screw 14 at the center of the back of the fixture 12 allows the fixture 12 to move along the adjustment direction, thus adjusting the test position, as the screw 14 is threaded into the internal threaded hole 18 at the center of the fixing plate 11. Once the position is determined, the fixing post 23 at the bottom of the fixture 15 inserts into the limiting hole on the adjustment strip 13, achieving the limiting fixation of the fixture 12. Simultaneously, the reset spring 16, sleeved on the reset post 24 at the bottom of the fixture 15, functions within the compression hole 20. The pressure detection module 7 serves to reset and fix the device, ensuring its stability and reliability. When pressure testing is required, the pressure detection module 7 is installed on top of the support frame 5. Multiple pressure sensors are located at the bottom of the pressure detection module 7. The piston shaft of the electric push rod 6 is fixedly connected to the top of the pressure detection module 7. After the electric push rod 6 is started, the piston shaft pushes the pressure detection module 7 downward, causing the pressure sensors at its bottom to contact the medical device under test. The pressure sensors sense the pressure on the surface of the medical device and convert the pressure signal into an electrical signal. After processing, the pressure test data is output, thereby realizing the detection of the pressure performance of the medical device. If a speed test is required for a medical device, the pressure detection module 7 can be replaced with a speed detection module 8 using a nut. The speed detection module 8 has a photoelectric speed sensor at its bottom. When the medical device is fixed on the test table 21 by the fixing frame 12, the photoelectric speed sensor emits light that shines on the medical device component whose speed needs to be tested. Rotational reflection marks and other factors on the medical device component will cause changes in the reflected light. The photoelectric speed sensor receives these changes in light and converts them into electrical signals. After processing, the speed of the rotating component of the medical device can be calculated, thus completing the speed test.

[0060] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
