Problems solved by technology

The existing syringe mounting device for high-pressure injectors is mainly through opening a gate on the injection head and setting a groove at the gate, so that the syringe is aligned with the gate groove and the bottom end of the syringe push rod is aligned with the injection head push. The top of the rod, close the gate, so as to fix the syringe, the whole process needs to be operated by both hands at the same time, and the operation is inconvenient

Abstract

The invention discloses a direct-inserting type high-pressure injector needle cylinder mounting device and method. The device comprises needle cylinders, a front end cover allowing the needle cylinders to penetrate through, tension sleeves arranged on the needle cylinders in a sleeving mode and fixed by the front end cover, gaskets for fixing the tension sleeves to the front end cover, slot rings arranged on the needle cylinders in a sleeving mode, torsional spring pieces fixed to the slot rings, needle cylinder bases for containing the slot rings and fixing the needle cylinders and a bottom plate matched with the bottoms of the needle cylinder bases. The direct-inserting type high-pressure injector needle cylinder mounting device is simple in structure, convenient to mount, capable of achieving automatic butt joint of the needle cylinders, convenient to operate and meanwhile capable of guaranteeing that a high-pressure injector works reliably.

Description

technical field [0001] The invention relates to a device and a method for installing a syringe of a straight-insert high-pressure injector. Background technique [0002] A high-pressure injector is one of the devices often used in medical equipment. It is used to inject liquids such as contrast agents and saline into the human body to enhance the effect of medical imaging such as X-ray or electromagnetic imaging. When installing and disassembling the syringe, the operation should be simple, convenient, efficient and safe. The existing syringe mounting device for high-pressure injectors is mainly through opening a gate on the injection head and setting a groove at the gate, so that the syringe is aligned with the gate groove and the bottom end of the syringe push rod is aligned with the injection head push. The top of the rod is closed to fix the syringe. The whole process requires two hands to operate simultaneously, and the operation is inconvenient. Contents of the inve...
