A safety syringe comprising a barrel having an opening at an end thereof and a bung positioned in the barrel and creating a volume between the opening and the bung. The safety syringe also comprises a handle portion secured to the barrel and a syringe plunger slidably engaged with the handle portion and moveable within the barrel on an inward stroke to drive the bung forwards within the barrel to cause a substance within the volume to be expelled from the opening. The safety syringe further comprises a rotation mechanism configured to rotate the syringe plunger within the barrel at a point during the inward stroke when the syringe plunger is in contact with the bung, such that a rotational force is applied to the barrel and a brake connected to the handle portion and configured to provide a frictional force to resist the rotational force applied to the barrel.

The utility model relates to the field of vacuum technology discloses a kind of adjustable sub-vacuum negative pressure generating device. Including: negative pressure bottle, negative pressure bottle is the vacuum device bottle that can be extracted, top is equipped with wheel disc cover;Wheel disc cover is cylindrical, and has been placed slot in side edge, rotating stick moves in the placement slot;Bung is located in wheel disc cover top;Connecting pipe, one end passes through bung, other end is connected with air extractor;Suction pipe, one end passes through bung, other end is connected with the required vacuumization device. Rotating stick moves in the placement slot of wheel disc cover drives rotatable wheel to rotate, cooperates fixed pin to limit sliding slot moving distance, so that connecting rod drives contraction piece to slide in T-shaped groove, adjust the gas extraction amount of inner diameter control hose, realize the adjustability of negative pressure generating device.

A method and system for monitoring wine in a barrel having a bung hole is provided. The system comprises a sensor enclosure, a sensor conduit, and an original bung. The sensor conduit is operably coupled to the sensor enclosure. The original bung comprises a passage hole for inserting the sensor conduit through the original bung. The original bung also comprises a space for inserting at least a portion of the sensor enclosure. This space does not extend through the original bung. The outer diameter of the original bung is determined by the diameter of the bung hole of the barrel.
