Precautions: Use of Medical Electrical System
Electrical devices which constitute KOWA system
This instrument constitutes medical Electric system by connecting with the following products.
- Personal computer
It is used in order to acquire the electronic images taken by KOWA . An application software KOWA VK-2 for
instance should be installed on the PC.
LCD monitor or other peripheral equipments are connected to PC.
When you install personal computer in patient environment, please use the below-mentioned “Multi-tap with Isolation Transformer”.
Precautions for System installation
●
All components of this medical electrical system may be installed within a limited patient environment when all
components are installed in accordance with the installation instructions using “Multi-tap with Isolation Transformer”, one
of the system components. And do not use “Multi-tap with Isolation Transformer” in this system for supplying the power
to any components other than this system.
●
Prerequisite for installing other components (a PC, printer, video capture printer, video monitor, or other devices) which
do not comply with IEC 60601-1 along with this system is that the electric power to the components is supplied from
“Multi-tap with Isolation Transformer”. The electric power to these components supplied from an electric source other
than Multi-tap with Isolation Transformer (e.g., directly from wall outlets) may cause increased enclosure leakage current
or potential difference between protective grounds, resulting in the injury to the patient or operator. Please use the
“Multi-tap with Isolation Transformer” for supplying the power to the components other than this instrument.
●
Any medical electrical equipment that is connected to this system to compose a medical system must comply with IEC
60601-1.
●
Any non-medical electrical equipment that is connected to this system to compose a medical system must comply with
safety standards of IEC or ISO provisions applicable to such a non-medical electrical equipment.
●
Do not use any additional multi-tap receptacle or extension power cable other than those specified to this system by
KOWA.
●
Power supply to this system or “Multi-tap with Isolation Transformer” must be provided individually. (Do not route the
power supply through other multi-tap receptacle to the system or “Multi-tap with Isolation Transformer”.)
●
The power cable for an electrical device that compose a medical system must have durability that meets IEC 60245/IEC
60227 or higher standards.
●
Assure that the power supply is turned off when connecting an electrical device to the system.
●
Do not turn on the power supply until all devices are completely connected.
●
Do not place or install the devices and the system components on the unstable or inclined table.
Precautions for “Multi-tap with Isolation Transformer”
●
“Multi-tap with Isolation Transformer” should use the one equipped with the rated output more than power consumption
of equipment to connect.
●
Do not place “Multi-tap with Isolation Transformer” directly on the floor. Water droplets during room cleaning may enter
the multi-tap resulting in the component failure.
●
The power supply cable to “Multi-tap with Isolation Transformer” must be connected to a power receptacle with a
protective ground terminal.
●
When using a "Multi-tap with Isolation Transformer" receptacle with a protective ground terminal, read the instruction for
use attached to it to familiarize yourself with the correct use before use.
Daily Maintenance and Cleaning
1. System components
●
Wipe the soiled outer surface with soft cloth from which water was firmly squeezed off. Do not wipe the exterior
of the system components with chemicals or solvents such as thinner or benzene. Because LCD monitor screen
covers easily get scratched, lightly wipe with soft cloth such as gauze.
●
Refer to the instruction for use provided with each device for details of device maintenance and cleaning.
2. Power cables, connecting cables, and connectors
●
Visually verify that all cables have no flaw or damage.
●
Visually verify that earth leads of all components and protective ground terminals are securely connected.
●
Disconnect the power cables from the power outlet when you do not use the system for a long period of time.
3. Others
●
When you change the components of this system, and connection after installing the system, you must build secure
system according to notes currently written here.
●
When you add a PC to the system for a archiving purpose, captured images are stored in the hard disk drive of
the PC. Back up the data stored in the hard disk drive regularly since hard disk drives may have a mechanical or
electrical failure.
