[0002] Medical devices refer to instruments, equipment, appliances, materials or other items used on the human body alone or in combination. Medical devices include tube components, which generally refer to: tubes used to transport gases or liquids, or to have a sealing effect, such as medical vacuum tubes, etc. When these medical devices are produced and processed, they need to be tested for air tightness, and the corresponding air tightness testing devices are generally used at this time.
[0003] The existing Chinese patent application with publication number CN116973037A discloses a medical device air tightness detection device, including a detection pool, support plates are fixed on the upper parts of both ends of the detection pool, a rotating tube connected in rotation is arranged on the support plate, a rotating disk connected to the rotating tube end is fixed, a connecting rod is fixedly connected to the center of the two rotating disks, a plurality of detection tubes are fixed at equal intervals on the outer wall of the rotating disk, a connecting piece for controlling on and off is arranged between the detection tube and the rotating disk, a plurality of pressing strips are evenly distributed on the outer wall of the end of the detection tube along the center thereof, and a pressing tube connected in sliding connection is also sleeved on the outside of the detection tube; the invention realizes rapid clamping between the instrument and the detection tube by moving the pressing tube by moving the moving assembly, and the instrument is alternately sent into the detection pool by rotating the rotating disk. While detecting, the staff removes the detected instrument and installs the instrument to be detected, which improves the clamping efficiency of the instrument itself on the one hand, and shortens the time consumption of batch detection on the other hand.
[0004] However, the air tightness detection equipment has the following defects when used:
[0005] 1. When the existing air tightness testing equipment performs air tightness testing on medical devices (generally medical pipes), the multiple groups of pipes to be tested are generally moved into the water pool for air tightness testing by means of rotating conveying of driving parts (motors, etc.). At this time, while performing the air tightness testing, the upper group of pipes that have completed the testing are disassembled, which effectively improves the efficiency of the testing. However, in the actual operation of the above scheme, in order to ensure the accuracy of the air tightness testing, when testing the pipes in the water pool, it is necessary to stop the operation of the driving parts (motors, etc.), and restart the driving parts after the testing is completed to perform the subsequent testing of the pipes. At this time, stopping and restarting the driving parts multiple times is not convenient, and it is easy to cause damage to the driving parts, which affects the efficiency of the subsequent testing of the pipes;
[0006] 2. When the existing air tightness testing equipment performs air tightness testing on medical devices such as pipes, the pipes are generally moved into a water pool, and then air is blown to observe whether bubbles are generated to complete the air tightness testing operation. At this time, the above method requires multiple manual disassembly and installation during actual operation.

Afterwards, before the test, the lifting assembly 20 is started by the controller to operate, driving the testing bracket 40 and the medical tube 70 connected to the output end through the installation box 80 to move up and down, so that the medical tube 70 located at the bottom of the testing bracket 40 can be underwater in the testing box 10. When the test is carried out, the air tightness testing assembly 60 is started, and the air tightness is tested by blowing air and observing whether bubbles are generated in the water inside the testing box 10.
