Infusion pump and method with twist lock

Abstract

The invention discloses an infusion pump with a rotary lock and a method thereof, comprising: a medicine box for accommodating a medicine liquid bag, a cover plate fixedly connected to the upper end of the medicine box and protruding with a locking part, a cover plate arranged above the cover plate and allowing The frame through which the locking portion passes, the front and rear half-shells that are fixedly arranged on both sides of the frame and engage with each other, and the rotating shaft that is accommodated by the front and rear half-shells and can be locked and matched with the locking portion. The present invention can effectively prevent the misoperation of non-medical staff from inadvertently loosening the medicine box components of the infusion pump during the infusion process, resulting in unregulated infusion under gravity, avoiding serious injury or death of patients, and ensuring product reliability. At the same time, manufacturing and maintenance costs can be reduced, product economy can be improved, and the lock has a simple structure, convenient assembly and self-locking.
