Abstract: A device for rapidly loading and releasing a syringe. A limiting flange and clamping flange are on an outer side wall of an end, connected to the device, of the syringe. The clamping flange is close to a rear end of the syringe. The device includes an injection head. An outer collar, middle plate, and inner collar are sequentially inside the injection head. The outer collar includes an upper and lower part that are disposed up and down. The inner collar includes an upper part of the inner collar and a lower part of the inner collar that are disposed up and down. Elastic structures are between the upper part of the inner collar and injection head and between the lower part of the inner collar and injection head. The injector syringe can be loaded onto the device and taken out rapidly if the syringe is rotated.

Abstract: A syringe and device for rapidly loading and releasing the syringe. A limiting flange and clamping flange are on a connection end of the syringe. The clamping flange is proximate to a rear end of the connection end and includes at least two clamping portions. The device includes an injection head, pushing ring, guide sleeve, and at least two bayonet locks. The bayonet locks are on the injection head by first elastic structures flexible along a radial direction. One end of the pushing ring stretches into the guide sleeve. A second elastic structure is between the pushing ring and guide sleeve. The other end of the pushing ring faces sides of the bayonet locks. Bump components are disposed on sides of the bayonet locks, with bump slots corresponding thereto. Clamping slots for insertion of the clamping portions are on an end face of the pushing ring.
