Problems solved by technology

[0014] However, the liquid syringe may not be properly mounted on the liquid injection device, for example, when the liquid syringe mounted on the liquid injection device is dropped during the injection operation
The operator needs to properly check that the liquid syringe is properly mounted on the liquid injection device to prevent it from falling, which is difficult to achieve in practice

Embodiment Construction

[0033]

[0034] Such as Figure 1-3 As shown, the liquid injection system 1000 according to the present invention has a liquid injection device 100, a liquid injector 200, an MRI device 300 as an imaging diagnostic device, and a cartridge adapter 400. When a fluoroscopic image of a patient (not shown) is captured by the MRI apparatus 300, the liquid injection apparatus 100 injects a liquid such as a contrast medium or saline from the liquid syringe 20 into the patient.

[0035] Such as image 3 As shown, the MRI apparatus 300 includes an imaging unit 301 as an image capturing mechanism and a control unit 302 connected to each other through a wired communication network (not shown). The imaging unit 301 captures tomography images of the patient, and the control unit 302 controls the operation of the imaging unit 301.

[0036] Such as figure 1 As shown in, the liquid syringe 200 includes a barrel member 210 and a piston member 220 slidably inserted into the barrel member 210. The ...

Abstract

Attachment detection means (131) is disposed on a chemical liquid injection device (110) at a position to which and from which a chemical liquid syringe (200) is attached and detached. This enables attachment and detachment of the chemical liquid syringe (200) to and from the chemical liquid injection device (110) to be detected, the detection result to be outputted and notified to a worker, and a piston drive mechanism (116) to be operated and controlled according to the detection result. Thus, the chemical liquid injection device (110) capable of detecting attachment and detachment of the chemical liquid syringe (200) is provided.

Description

Technical field [0001] The present invention relates to a liquid injection system for injecting liquid into a patient by relatively moving a cylinder part and a piston part of a liquid syringe, the liquid syringe being mounted on a liquid injection device, and, in particular, to a liquid syringe in which A liquid injection system that is mounted to a liquid syringe through a cartridge adapter. Background technique [0002] Currently available imaging diagnostic devices for capturing fluoroscopic images of patients include CT (computed tomography) scanners, MRI (magnetic resonance imaging) devices, PET (positron emission tomography) devices, Ultrasound diagnostic device, angiography device and MRA (MR angiography) device. [0003] When such an imaging diagnostic device is used to capture a fluoroscopic image of a patient, it is occasionally necessary to inject a liquid such as a contrast medium or saline into the patient's body. Liquid injectors that automatically inject liquids i...
