Embodiment Construction

[0025] Below in conjunction with embodiment, the present invention is further described, but does not constitute any restriction to the present invention, anyone makes the limited number of amendments in the scope of claims of the present invention, still within the scope of claims of the present invention.

[0026] refer to Figure 1-Figure 4 , a squeeze roller for a roller-type high-pressure injector of the present invention includes a wheel disc 1 . Wherein, the wheel disc 1 is connected with the motor in the high-pressure injector to realize the rotation of the wheel disc 1 . A central hole is provided on the wheel disc 1 for installing the rotating shaft of the motor. A keyway 15 communicating with the central hole 14 is provided on the wheel disc 1 at the outer edge of the central hole 14 . That is, the wheel disc 1 is connected to the rotating shaft through a flat key, so as to improve the reliability of the connection between the two. Two mounting holes are provided...

Abstract

The invention discloses an extrusion roller for a roller type high-pressure injector, relates to an injection mechanism of the high-pressure injector, and solves the technical problems that the working efficiency is influenced and a larger risk exists in an injection mode of an electric injector. The extrusion roller comprises a wheel disc; a plurality of extrusion wheels are installed on the wheel disc, and a pre-pressing assembly is arranged between every two adjacent extrusion wheels. The extrusion roller is practical, convenient, safe, reliable and high in stability, the injection effect is effectively improved, and the risk that the injection pipeline falls off can be effectively reduced.

Description

technical field [0001] The present invention relates to a high-pressure injector injection mechanism, and more particularly, it relates to a squeeze roller for a roller-type high-pressure injector. Background technique [0002] As an auxiliary equipment in the radiology diagnosis and treatment system, the high-pressure injector is gradually used clinically with the development of technologies such as X-rays, fast film changers, image intensifiers, and artificial contrast agents. The basic function of the high-pressure injector is to quickly and accurately inject a sufficient amount of high-concentration X-ray contrast agent into the examination site, so as to perform diagnostic imaging and treatment on the lesion. At present, in order to realize rapid injection, the injection is mainly performed by connecting an electric injector at one end of the injection pipeline. Specifically, when injecting, first install the piston rod and the injection barrel on the electric injector...
