Therefore, the venous access is also the life channel of the patients, which is particularly important for the patients. On the other hand, critically ill patients will bring in more drainage tubes after surgery. The drainage tubes can ensure that the waste fluid in the patient's body is drained out of the patient's body. The unplanned detachment of the drainage tubes placed during the operation will not only delay the patient's recovery from the disease, but also increase the patient's pain and economic losses due to another surgery.
