Problems solved by technology

[0017] In this case, the filling of the drug solution is confirmed by using the refraction increase and decrease of the scene visually recognized by the syringe parts, but there may be an erroneous judgment that the drug solution syringe that is not filled with the drug solution is judged to be filled due to carelessness.

Embodiment Construction

[0053] (Structure of embodiment)

[0054] Hereinafter, an embodiment of the present invention will be described with reference to the drawings. The medical solution injection system 1000 of this embodiment, as shown in FIGS. The syringe 200 injects a medical solution L such as a contrast medium and physiological saline into a patient (not shown) whose fluoroscopic image is captured by the MRI apparatus 300 .

[0055] The MRI apparatus 300 , as shown in FIG. 3 , has a perspective imaging unit 301 and an imaging control unit 302 as an imaging actuator, and the perspective imaging unit 301 and imaging control unit 302 are connected through a communication network 311 by wire. The fluoroscopic imaging unit 301 captures fluoroscopic images of the patient, and the imaging control unit 302 controls the operation of the fluoroscopic imaging unit 301 .

[0056] The drug solution injector 200 is composed of a syringe member 210 and a piston member 220 as shown in FIG. 1 , and the pist...

Abstract

A medical liquid injection system enabling the simultaneous confirmation of both the fact that a medical liquid syringe is being properly installed on a medial liquid injection device and the fact that the medical syringe has been filled with a medical liquid. A figure (400) providing a predetermined shape when viewed from the above through a medical liquid syringe (200) filled with a transparent medical liquid (L) is indicated in a split manner on the lower surface of the medical liquid syringe (200) and the upper surface of a medical liquid injection device (100). Then, when the medical liquid syringe (200) is properly held by the medical liquid injection device (100), the figure on the lower surface of the medical liquid syringe (200) and the figure on the upper surface of a medical liquid injection device (100) are appropriately combined. If the medical liquid syringe (200) has been filled with the transparent medical liquid in this state, the combined figure is visible from the above of the medical liquid syringe (200) as the figure of the predetermined shape. Thus, the visual perception enables the simultaneous confirmation of both the fact that the medical liquid syringe (200) is being properly held and the fact that the syringe has been filled with the medical liquid (L).

Description

technical field [0001] The invention relates to a liquid medicine injection system, which makes the syringe part and the piston part of the liquid medicine injector relatively move in the liquid medicine injection device to inject the liquid medicine to the patient, especially relates to the liquid medicine syringe installed in the syringe through a syringe adapter. The liquid medicine injection system of the liquid medicine injection device. Background technique [0002] At present, there are CT (Computed Tomography) scanners, MRI (Magnetic Resonance Imaging) devices, PET (Positron Emission Tomography) devices, SPECT (Single Photon Emission Computed Tomography) devices, ultrasonic diagnostic devices, Vascular device MRA (MRAngio) device, etc. [0003] When using the above-mentioned apparatus, it is sometimes necessary to inject a medical solution such as a contrast medium or physiological saline into a patient, and a medical solution injection device that automatically exe...
