Technical Field

[0002] Patients need various drainage tubes (such as chest drainage tubes, abdominal drainage tubes, pericardial drainage tubes, etc.) due to diseases and treatment. During use, unplanned extubation may occur due to various reasons, such as the patient accidentally pulling, improper fixation by medical staff, discomfort after tube placement, and self-extubation by the patient, or accidental extubation due to impaired consciousness. Domestic and foreign literature reports that the incidence of unplanned extubation is 0.2% to 14.6%. Once it occurs, it can aggravate the patient's pain, prolong hospitalization time, increase the economic burden, and even threaten the patient's life safety. The existing monitoring method for catheters is mainly achieved by regular observation by medical staff, which has a time lag and increases the workload of medical staff. Whether it is possible to design an alarm device to prevent the slippage of the drainage tube can play a timely reminder role, effectively reduce the probability of drainage tube slippage, and avoid the damage to the patient caused by the slippage of the drainage tube without anyone noticing.
