The invention provides systems and methods for reducing injury to patients by dislodgement of implanted or attached medical tubing. The inventive systems and methods provide medical tubing with a releasable magnetic connection. When a stretching force is applied to the medical tubing that would cause the implanted or attached portion to be pulled or separated from the patient, the medical tubing instead separates at the point of the releasable magnetic connection, preventing the force from reaching the portion of the tubing implanted in or attached to the patient, thereby reducing the risk of injury to the patient. The releasable magnetic connection allows the tubing to be easily reconnected once the stretching force on the tubing has been terminated.

Disclosed is an atomizer drug delivery nozzle, and an intelligently self-adjustable atomizer drug delivery apparatus and a method for using same, characterized in that: a nozzle body (2) is provided with an exhalation detection valve (3) unidirectionally opening toward the outside of a nozzle and an inhalation detection valve (4) unidirectionally opening toward the inside of the nozzle, wherein bodies (3.2, 4.2) of the two valves (3, 4) are respectively provided with a first magnet (3.3) and a second magnet (4.3); a tube wall of the part of the nozzle body (2) that is close to the first magnet (3.3) is provided with a first sensor (3.1), and a tube wall of the part of the nozzle body (2) that is close to the second magnet (4.3) is provided with a second sensor (4.1); the first sensor (3.1) and the second sensor (4.1) are respectively connected to an atomizer control system; and the atomizer control system comprises an intelligent module for detecting a valve state during exhalation and inhalation, and controls a working state of the atomizer according to a received valve opening state detection signal sent by the first sensor (3.1) and the second sensor (4.1).
