Abstract

[0002] In the field of medical device production, DL locking joints and catheters are commonly used in clinical medical devices after assembly. After assembly, DL locking joints and catheters are mainly used as part of the hemodialysis pipeline for kidney patients to undergo hemodialysis, and become the connecting part between the patient's blood vessels and the dialysis machine. Therefore, whether the two are assembled in place is related to the patient's life safety. At present, whether the DL locking joint and catheter are assembled in place is mainly observed and tested manually. The operator puts the assembled DL locking joint and catheter part above a strong light source, and then observes with the human eye whether the catheter is assembled to the installation stop surface of the DL locking joint, and selects and distinguishes qualified products from unqualified products. This manual detection method is not only inefficient, but also after working for a long time, the human eye will produce severe fatigue under the stimulation of the strong light source, which not only affects the accuracy of product detection, but also affects the eye health of the inspector. Therefore, it is of great significance to invent a simple, practical, high detection accuracy, and high detection efficiency DL locking joint and catheter assembly after visual detection mechanism.
