Syringe, and Device for Rapidly Loading and Releasing the Same
First Claim
1. A device for rapidly loading and releasing a syringe, wherein:
- a limiting flange and a clamping flange are disposed on an outer side wall of a connection end of a syringe, the clamping flange is close to a rear end of the connection end of the syringe, and an outer circle of the limiting flange is of an oval shape;
the device includes an injection head, and an outer collar, a middle plate, an inner collar are disposed sequentially inside the injection head;
the outer collar includes an upper part of the outer collar and a lower part of the outer collar 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, and elastic structures are disposed between the upper part of the inner collar and the injection head and between the lower part of the inner collar and the injection head;
during loading, the syringe is inserted into the injection head, the clamping flange passes through the outer collar and the middle plate and then pushes the inner collar away, the upper part of the inner collar moves upwards, and the lower part of the inner collar moves downwards;
after the clamping flange passes through the inner collar, under the action of the elastic structures, the upper part of the inner collar and the lower part of the inner collar are restored, a side of the clamping flange abuts on a side of the inner collar, and a side of the limiting flange abuts on the middle plate, so that the syringe is positioned along an axial direction;
in this case, the upper part of the outer collar and the lower part of the outer collar are fixed, an inner circle of the outer collar formed by the upper part of the outer collar and the lower part of the outer collar is of an oval shape matching the outer circle of the limiting flange, and the limiting flange is fit into the oval inner circle of the outer collar; and
during releasing, the syringe is rotated, the limiting flange pushes to enable the upper part of the outer collar and the lower part of the outer collar to respectively move upwards and downwards, the upper part of the outer collar and the lower part of the outer collar respectively drive, by means of connection pieces, the upper part of the inner collar and the lower part of the inner collar to move upwards and downwards;
the inner collar is opened, the clamping flange is moved outwards to be disengaged from the inner collar, to release the syringe;
at the same time, the limiting flange is disengaged from the outer collar, and under the action of the elastic structures, the inner collar and the outer collar are restored.

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.
