20150202425 | STOPCOCK FLOW PATH SWITCHING DEVICE - This stopcock flow path switching device includes: a three-way stopcock having a flow path switching cock and provided to, by switching of the flow path switching cock, allow flow path switching between a state in which a contrast agent introducing flow path is formed by coupling a flow path on the patient side to a flow path on the injector head side and a state in which a blood pressure measuring flow path is formed by coupling the flow path on the patient side to a flow path on the blood pressure transducer side; and a clamp mechanism for closing the flow path of the three-way stopcock communicating with the injector head side, in the state in which the blood pressure measuring flow path is formed. | 07-23-2015 |
20140288423 | PRIMING METHOD - The priming method includes the steps of: in a state where a contrast agent bag containing a contrast agent is coupled to a second tube moving a second piston in a second syringe backward to introduce the contrast agent to the second syringe, and with a first tube kept open, moving the second piston in the second syringe forward to discharge air in the second syringe to the outside and to fill the first tube with contrast agent. | 09-25-2014 |
20140249412 | NJECTOR HEAD WITH ROTATION MECHANISM - An injector head with rotation mechanism allows selection between a state in which a syringe assumes a priming orientation with a through hole of the syringe positioned upper than the injector head body, and a state in which the syringe assumes a contrast agent injectable orientation with the through hole of the syringe positioned lower than the injector head body. | 09-04-2014 |
20130340608 | JOINT MECHANISM - In the joint mechanism, when connecting a plunger to a piston, after engaging members of a plunger-side engaging region in a retracted state pass through a first engaging wall region of a piston-side engaging region, the engaging members of the plunger-side engaging region come into a projected state in a second engaging wall region and the projected state of the engaging members is fastened by a fast block, and thereby, the plunger-side engaging region engages with the piston-side engaging region. | 12-26-2013 |
20130184576 | VALVE-EQUIPPED HAND SWITCH AND CHEMICAL LIQUID INTRODUCTION SYSTEM - In a valve-equipped hand switch and a chemical liquid introduction system, a contrast medium in a syringe is delivered to a patient line through a first port, a main passage around a spacer portion, and a second port. Furthermore, a pressure (about 300 psi) of the contrast medium delivered by a chemical liquid introduction device is transmitted as a reaction force through a third plunger from a handle portion of an operation piston held by an operator. As such, the operator can directly feel the pressure of the introduced contrast medium, which gives a sense of ease to the operator during operation. | 07-18-2013 |
20100069748 | SYRINGE-LIKE HAND SWITCH - At the insertion movement of plunger member in cylinder member, a photosensor is in the position of sensing the movement of slit area. As a result, when the plunger member is pressed inward by an operator, light transmission zones and light shielding zones alternately provided in the slit area are sensed by the photosensor. Accordingly, there can be provided a syringe-like hand switch such that in the chemical introduction control of injector head for injection of chemicals, such as a contrast medium, in patients, both parameters for injection speed and injection quantity can be controlled by the senses at use of conventional syringes. | 03-18-2010 |
