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 roller extrusion device for a roller high-pressure injector of the present invention includes a driving mechanism and an extrusion roller 1 . The driving mechanism is installed in the high-pressure injector and is used to drive the extrusion roller 1 to rotate. The extrusion roller 1 is rotatably mounted on the support plate 2, and the driving end of the driving mechanism is connected with the extrusion roller 1. An extrusion plate 3 for extruding the injection pipe with the extrusion roller 1 is slidably installed on the support plate 2 below the extrusion roller 1 . That is, the injection pipeline is squeezed by the extrusion rol...

The invention discloses a roller extrusion device for a roller type high-pressure injector, relates to an injection mechanism of the high-pressure injector, and solves the technical problem that the current electric injection consumes more materials. The roller extrusion device comprises a driving mechanism and an extrusion roller; the driving mechanism is installed in the high-pressure injector, the extrusion roller is rotatably installed on the supporting plate, and the driving end of the driving mechanism is connected with the extrusion roller; an extrusion plate used for extruding the injection pipeline together with the extrusion roller is slidably mounted on the supporting plate below the extrusion roller, a positioning plate is slidably mounted on the supporting plate below the extrusion plate, and the positioning plate is elastically connected with the extrusion plate; and a lifting assembly for lifting the positioning plate and the extrusion plate is mounted on the supporting plate below the positioning plate. The roller extrusion device is convenient and fast to operate, practical and reliable, the problem that the number of consumed materials is large is solved, the injection pipeline can be effectively protected, and the reliability of the high-pressure injector is greatly improved.
Description
technical field [0001] The present invention relates to an injection mechanism of a high-pressure injector, and more particularly, it relates to a roller extrusion device 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. In order to achieve fast injection, most of the current injection mechanisms are electric injection to achieve injection. That is, the motor is installed on the injection barrel, and the driving end of the motor is connected to the push rod; the inj...
