Description
Technical field
It the utility model is related to medical electric apparatus monitoring technical field, in particular to a kind of can carry out remote monitoring
Medical isolating power system.
Background technology
As electromedical equipment is in the extensive use of hospital, it has been found that patient and doctor got deeply stuck in electronic instrument and
Among the encirclement of equipment, before leakage current is also far longer than to the potential threat that patient is formed, especially patient in operation or
Under narcosis, various electrodes, sensor are inserted directly into patient body, directly flow through patient's if any extremely faint electric current of letting out
Heart, may result in patient get an electric shock it is dead, medically referred to as microdot is hit.At present, China most of hospital's distribution systems connect
Ground form uses TN systems.It is mostly metallic short circuit that the system earth, which hinders,.Because hindering electric current larger, make the overcurrent such as breaker
Shielding apparatus acts, and causes to have a power failure.Obvious TN systems can not meet practicality of some important places to uninterrupted power supply in hospital
It is required that.Therefore the class place of hospital 2：Such as Emergency Room, all operating rooms of center Surgery；All CU wards（Including ICU,
CCU, NICU, PICU, SICU etc.）；Cardiac catheter involvement room and energy pipe Screening room etc., IT insulating power supplies should be used to power.
The present medical isolating power sold on the market（IT）System, being generally used for the standard configuration of every operating room is
Totally 5, isolating transformer, insulating monitor, current transformer, D.C. regulated power supply, alarm indication instrument, formed a set of independent
Monitoring system.But a complete monitoring system can not be formed for the IT system of medical space so that in daily dimension
, it is necessary to which staff checks each operating room one by one in shield, inconvenience is brought.Secondly 5 devices of every operating room standard configuration,
It is very expensive in price.
The content of the invention
The purpose of this utility model is that providing one kind is easy to staff's regular maintenance and real-time query, cost-effective
Medical isolating power system.
The utility model is achieved through the following technical solutions：A kind of medical isolating power system that can carry out remote monitoring
System, including be the whole isolating transformer that power supply is provided and the nurse station of monitoring patient's condition；The isolating transformer is gone here and there successively
Insulating monitor, external alarm are associated with, the external alarm is also associated with alarm indication instrument, the monitoring patient's condition
Nurse station is connected with control room, and test console is connected with insulating monitor；Isolating transformer also by current transformer successively
Some insulation testers in parallel；The nurse station of the monitoring patient's condition includes in parallel with insulation fault tester some bear
Carry circuit, the load circuit is additionally provided with switch and positioning transformer, the positioning transformer on the load circuit with absolutely
Edge detector connects.
Medical isolating power（IT）In system, I represents that mains side does not have working earthing, or by high resistance grounding;T tables
Show that load side electrical equipment carries out ground protection.IT system is when power supply distance is not very long, the reliability height of power supply, security
It is good.It is generally used for not allowing the place having a power failure, or requires the place strictly continuously to power, the operating room of hospital, first aid
The class place of room and ICU rooms etc. two must use IT system.With IT mode electric power systems, i.e. mains neutral point is earth-free, once
Equipment leakage, single-phase earth leakage current very little will not destroy the balance of supply voltage, so being than mains neutral point ground connection
Unite safe and reliable.Medical isolating power, it is exactly briefly isolating transformer and insulating monitor and alarm terminal（Also include
Transformer and alarm terminal power supply）Three are put together.Power supply the principle is very simple, is exactly plainly TN using isolating transformer
Power supply becomes earth-free IT power supplies, and an actually isolating transformer can be achieved with the function of application, but in view of system
Long-time stability, it can just put insulating monitor and carry out the overall dielectric level of online real-time detection.
It is well known that when electrical equipment is directly leaked electricity to human heart and is more than 10uA, the microshock to patient can be caused.
And the action response value of the earth leakage protection such as RCD, ELCB typically used in common architectural switch is mA（Such as 30mA）Level,
The needs of medical field far can not be met.Therefore, it is now important to the operating room in medical field, ICU, CCU etc. in the world
Place generally use is local " neutral conductor ungrounded supply system "（That is IT system or as " medical isolating power system "）.Pass through
3KVA-10KVA isolating transformer is powered to these places, can prevent the leakage current in other current supply circuits by connecing first
Ground wire is scurried on operating room, ICU, CCU medical electronic equipment and the safety of patient is constituted a threat to.Its purpose is exactly to ensure
A safe and reliable power supply is provided to the medical electrical equipment in the place, to ensure the safety of patient.The heart is touched in electric conductor
When dirty (for example, opening the operation of heart or embedding pacemaker), what is flowed through between the conductor of common safety ground is trickle
Electric current can cause microshock and dead potentially possible.And isolating transformer is just as a door, by the non-of Medical Treatment Area
The electric wiring of protection zone and protection zone is separated, and all energized conductors are isolated with ground in protection zone, prevent circuit
Dangerous currents cause microshock on insulating barrier.Insulating monitor must be used cooperatively with isolating transformer, for continuous monitoring every
From the resistance and electric current between the energized conductor and ground of Circuit Fault on Secondary Transformer, for example, flowed out in surgical procedure external blood and
Metal operating table may make patient form a path with ground, expected dangerous currents thus be present, once medical electric
The electric conductor of sub- equipment also forms path (as leak electricity) over the ground, it will cause macroshock (not all electric current all flows through heart) or
Microshock (all electric currents all flow through heart).General power supply grid is using greatly as reference potential, and electric current in phase line can be with
By any uninsulated passage, loop is formed over the ground, and this is the basic reason of electric shock.It is to use isolating transformer to isolate power supply
Power supply, for power supply after isolating transformer, the ground in former power network has no longer been reference potential.Any output of isolating transformer
Line all can not form loop with ground, can only form loop between two output lines, this provides for improved the reliability of power supply.
The operation principle of the technical program is, by an external alarm indication and tester, to be above common alarm indication
Instrument, play a part of a host computer.It can obtain the internal unit parameter of EDS and RCM systems by voluntarily setting（Alarm
Address, test address etc.）, it is exactly to apply installing in multiple IT and EDS system for user, staff is directly in distribution
On-line monitoring situation is inquired about in room, and maximum can realize the integral monitoring to 30 monitoring systems.
Preferably to realize the utility model, further, the power supply circuit is powered for three phase mains.
Preferably to realize the utility model, further, the isolating transformer is SG three-phase transformers.
Preferably to realize the utility model, further, the power supply circuit is powered for single phase poaer supply.
