Neonatal PICC catheterization is mainly used in premature infants and critically ill children. Their vein conditions are poor and puncture is difficult. Completing the catheterization requires a high level of professional skills. Therefore, a large number of training simulations are needed in normal times to train a group of well-trained medical personnel to be responsible for the maintenance of PICC patients' catheters and prevent the occurrence of complications. This is crucial to ensure the safe use of drugs for patients, so PICC maintenance training simulation simulators are used;

[0004] However, the above scheme still has the following problems during use: during use, the simulation of the operating state is single, which leads to insufficient experience in PICC catheter maintenance, making it impossible for nurses to complete their work with high efficiency, and due to unfamiliarity with the operation, other problems such as PICC catheter dislocation are easily caused during maintenance.

[0005] Therefore, we propose a simulation simulator for PICC maintenance training to solve the above problems. Utility Model Content
