• 1. GENERAL

  1.2 Service Manual ECG-9620

  General Information on Servicing

  Note the following information when servicing the
  instrument.

  CAUTIONSSafety

  • There is the possibility that the outside surface of the
  instrument,

  such as the operation keys, could be contaminated by
  contagious

  germs, so disinfect and clean the instrument before servicing
  it.

  When servicing the instrument, wear rubber gloves to protect

  yourself from infection.

  • There is the possibility that when the lithium battery is
  broken, a

  solvent inside the lithium battery could flow out or a toxic
  substance

  inside it could come out. If the solvent or toxic substance
  touches

  your skin or gets into your eye or mouth, immediately wash it
  with a

  lot of water and see a physician.

  Liquid ingress

  The instrument is not waterproof, so do not install the
  instrument

  where water or liquid can get into or fall on the instrument. If
  liquid

  accidentally gets into the instrument or the instrument
  accidentally

  drops into liquid, disassemble the instrument, clean it with
  clean

  water and dry it completely. After reassembling, verify that
  there is

  nothing wrong with the patient safety checks and function/

  performance checks. If there is something wrong with the

  instrument, contact your Nihon Kohden representative for
  repair.

  Environmental Safeguards

  Depending on the local laws in your community, it may be illegal
  to

  dispose of the lithium battery in the regular waste collection.
  Check

  with your local officials for proper disposal procedures.

  Disinfection and cleaning

  To disinfect the outside surface of the instrument, wipe it with
  a non-

  abrasive cloth moistened with alcohol. Do not use any other

  disinfectants or ultraviolet rays to disinfect the
  instrument.

• 1. GENERAL

  Service Manual ECG-9620 1.3

  Caution — continued

  Transport

  • Use the specified shipment container and packing material
  to

  transport the instrument. If necessary, double pack the
  instrument.

  Also, put the instrument into the shipment container after
  packing so

  that the buffer material does not get inside the instrument.

  • When transporting a board or unit of the instrument, be sure
  to put it

  in a conductive bag. Never use an aluminum bag to transport
  a

  board or unit. Also, never use a styrene foam or plastic bag
  which

  generates static electricity to wrap the board or unit of
  the

  instrument.

  Handling the instrument

  • Because the outside surface of the instrument is made of
  resin, the

  outside surface of the instrument is easily damaged. So when

  handling the instrument, remove clutter from around the
  instrument

  and be careful to not damage the instrument or get it dirty.

  • Because most of the boards in the instrument are multilayer
  boards

  with surface mount electrical devices (SMD), a special tool
  is

  required to remove and solder the electrical devices on it. To
  avoid

  damaging other electrical components, do not remove and
  solder

  SMD components yourself.

  Measuring and Test Equipment

  Maintain the accuracy of the measuring and test equipment by

  checking and calibrating it according to the check and
  calibration

  procedures.

  1.4 Service Manual ECG-9620

  Service Policy, Service Parts and Patient Safety Checks

  Service Policy Our technical service policy for this instrument
  is to replace the faulty unit, boardor part or damaged mechanical
  part with a new one. Do not perform electrical

  device or component level repair of the multilayer board or
  unit. We do not support

  component level repair outside the factory for the following
  reasons:

  • Most of the boards are multilayer boards with surface mount
  electrical

  devices, so the mounting density of the board is too high.

  • A special tool or high degree of repair skill is required to
  repair the multilayer

  boards with surface mount electrical devices.

  Only disassemble the instrument or replace a board or unit in an
  environment

  where the instrument is protected against static
  electricity.

  Refer to “Replaceable Parts List” of this manual for the service

  • Do not use a battery pack which is damaged, such as from
  falling.

  There is a gas discharge valve inside the battery and if this
  valve is

  damaged, the gas cannot be discharged, causing the battery pack
  to

  explode.

  • Do not subject the battery pack to a strong mechanical shock.
  The

  susbstance liquid inside the battery leaks and explodes.

  • If the battery pack is damaged and substance liquid inside
  the

  battery contacts the eyes or skin, wash immediately and
  thoroughly

  with water and see your physician. Never rub your eyes,
  otherwise

  you may lose your eyesight.

  • Only charge the battery pack with the ECG-9620 cardiograph. If
  any

  other battery charger is used, abnormal current flows and
  the

  substance liquid inside the battery leaks and the battery
  explodes.

  • Do not connect the battery pack to an AC outlet or lighter
  socket in a

  car. The substance liquid inside the battery leaks out and the
  battery

  pack explodes.

  • The battery has + and – polarity. Make sure that the battery
  is

  installed with the correct polarity direction. Otherwise,
  the

  substance inside the battery leaks out and the battery pack
  explodes.

  • Use only the SB-901D battery pack.

  WARNING• Do not immerse the battery pack in water or seawater.
  The battery

  heats up and rusts and the substance liquid inside the battery
  leaks.

  • Never use a battery pack which is damaged, discolored or
  has

  leakage. A damaged battery pack explodes if used.

  • Do not leave the battery pack unused for more than one year.
  Thebattery may leak.

• 1. GENERAL

  Service Manual ECG-9620 1.9

  CAUTION• Do not charge the deteriorated battery pack. Otherwise,
  the

  cardiograph cannot operate on battery power.

  • Do not expose the battery pack to direct sunlight or leave in
  a high

  temperature place. The life time of the battery pack may be

  shortened, the performance of the battery pack may be degraded
  and

  the substance liquid inside the battery may leak.

  • Do not leave the battery pack where patients can reach it.

  • Before disposing of the battery pack, check with your local
  solid

  waste officials for details in your area for recycling options
  or proper

  disposal. The battery is recyclable. At the end of its useful
  life, under

  various state and local laws, it may be illegal to dispose of
  this

  battery into the municipal waste stream.

  CAUTION

  • Enter the patient information correctly. Otherwise, the ECG
  data may

  be lost or mixed up with another patient’s ECG data.

  ECG recording judgement

  • The cardiograph provides automatic ECG analysis function.
  The

  automatic ECG analysis is performed for acquired ECG
  waveforms

  only and does not reflect all conditions of the patient. The
  results of

  the analysis may not correspond to the judgment of a
  physician.

  • Overall judgement must be performed by the physician,
  referring to

  the analysis result, clinical findings, and other examination
  results.

  After the physician’s overall judgement, the analysis results
  should

  be signed or initialed by the physician.

  • Take care when judging the ECG recording because the 25 Hz
  EMG

  filter may cause greater distortion of P-waves and QRS-waves

  depending on the waveform shape. The characteristics of the
  EMG

  filter are similar to a conventional analog filter.

  • Do not use the output signal from the output connector for
  a

  synchronization signal such as the synchronized
  cardioversion

  signal. There is a time delay between the input ECG signal
  and

  output signal.

  • When the cardiograph operates on battery power and large
  leakage

  current is input from the connected external instrument, ground
  the

  cardiograph or use an isolation transformer for the external

  instrument. Failure to follow this caution may cause electrical
  shock

  to patient and operator.

  • Use only the KD-103E cart for the cardiograph. When another
  cart is

  used, the cardiograph may fall off or the cart may tip over.

  Operation

• 1. GENERAL

  1.10 Service Manual ECG-9620

  Maintenance

  Caution — continued

  • Never use the cardiograph with its side panel downward.
  Failure to

  follow this caution may cause the cardiograph to fall over or
  cause

  battery liquid leakage.

  NOTE• When using the battery pack and the battery operation lamp
  is

  blinking in orange, measurement results may not be saved.

  CAUTION• Before maintenance (cleaning, disinfection), make sure
  that the

  cardiograph is turned off and the power cord is removed from the
  AC

  outlet and cardiograph. Otherwise, the operator may get an
  electrical

  shock and the cardiograph may malfunction.

  • Before battery replacement, make sure that the cardiograph is
  turned

  off and the power cord is removed from the AC outlet and

  cardiograph. Otherwise, the operator may get an electrical
  shock.

  • Do not disassemble or repair the cardiograph. Disassembly
  and

  repair must be performed by qualified service personnel.

Attorneys of record and parties who are ECF registered users will receive one free electronic copy of all documents filed electronically. Attorneys, parties, and pro se litigants may view civil and criminal dockets as well as electronically filed documents via the Internet using the PACER (Public Access to Court Electronic Records) portion of the system. Learn more. It is the responsibility of the filer to maintain records and information regarding charge card transactions associated with electronic filings. All of this information is provided by the filer by electronic receipt when the electronic filing is submitted and further information is provided by electronic notification when a new case is processed and opened.

Once assigned login credentials, please click here for complete instructions. The Ethics Commission’s Electronic Case Filing system (ECF) will only accept documents in a portable document format (PDF). Although there are two types of PDF documents, electronically converted PDFs and scanned PDFs, electronically converted PDFs are preferable for filing using the ECF system. Electronically converted PDFs are created from word processing documents (MS Word, WordPerfect, etc.) using Adobe Acrobat or similar software. They are text searchable and their file size is small. Scanned PDF’s are generally not searchable and have a larger file size. Registration is accomplished by completing an ECF Registration Form, a copy of which is available by clicking here.A document shall not be considered filed until the system generates an NEF. The filer shall retain a paper or digital copy of the NEF, which shall serve as the Ethics Commission’s date-stamp and proof of filing. Any pleading or other paper served by electronic means must bear a certificate of service stating that the document has been filed and that it will be served electronically to all parties of record who have registered with the ECF system. All pleadings and other papers must be served on all parties who have not registered with the ECF system in the traditional manner. Any pleading or other paper served in the traditional manner must bear a certificate of service stating the manner in which the document has been filed. All electronic transmissions of documents must be completed prior to 5:00 p.m., Eastern Standard Time, in order to be considered timely filed that day. Where a specific time of day deadline is set by the Hearing Officer, the electronic filing must be completed by that time. For example: All electronically filed documents must include a signature block and must set forth the individual’s name. The individual’s mailing address, telephone number and e-mail address must be included in the text portion of the e-mail sent to the Ethics Commission to which the document to be electronically filed is attached. For example: By submitting such a document, the filer certifies that each of the other signatories has expressly agreed to the form and substance of the document and that the filer has their actual authority to submit the document electronically. The filer shall retain any records evidencing this concurrence for future production, if necessary, until two (2) years after the expiration of the time for filing a timely appeal. A non-filing signatory or party who disputes the authenticity of an electronically filed document containing multiple signatures must file an objection to the document within seven (7) days of the date on the NEF. The filer shall retain the original for future production, if necessary, for two (2) years after the expiration of the time for filing a timely appeal. Please note that affidavits should not contain the home addresses of any individuals. At this time, the Ethics Commission will not permit the electronic filing of sealed documents. A party may electronically file a motion to file a document under seal. If the motion is granted, the assigned Hearing Officer will file an order authorizing the filing of the document under seal. The filer shall then deliver the document to the Ethics Commission for conventional filing under seal. Excerpted material must be clearly and prominently identified as such. Users who file excerpts of documents do so without prejudice to their right to timely file additional excerpts or the complete document, as may be allowed by the Hearing Officer. Responding parties may timely file additional excerpts or the complete document that they believe are directly germane. Documents significantly larger than 2 megabytes will be rejected by the ECF system. Filers should take into consideration that scanned images take up considerably more space on the system than PDF files containing electronically generated documents converted to PDF. 2. Because documents scanned in color or containing a graphic take much longer to upload, filers must configure their scanners to scan documents at 200 dpi and in black and white rather than in color. Documents appearing in color in their original form, such as color photographs, may be scanned in color and then attached to the main document and sent through the ECF system. 3. The filer is required to verify the readability of scanned documents before filing them electronically with the Ethics Commission. 4. Documents or exhibits submitted conventionally shall be served on other parties as if not subject to these procedures. When filing the document electronically, two versions of the document must be submitted: (1) a redacted version, and (2) the original un-redacted version.

НАЗНАЧЕНИЕ И ОБЛАСТЬ ПРИМЕНЕНИЯ

Электрокардиографы ECG 9620 К/М, ECG 9320К (далее по тексту -ЭКГ) предназначены для регистрации, измерения биоэлектрических потенциалов сердца по 12 общепринятым отведениям.

Область применения ЭКГ: кабинеты функциональной диагностики поликлиник, медико-санитарных частей, кардиологических центров, санаториев и других медицинских учреждений, которые решают задачи массовых осмотров населения, палаты интенсивного наблюдения, научно-исследовательские медицинские подразделения, учреждения скорой и неотложной помощи.

ОПИСАНИЕ

Электрокардиографы ECG 9620 К/М, ECG 9320К — это электрокардиографы, позволяющие оперативно снимать электрокардиограмму в различных условиях.

Принцип действия ЭКГ основан на съеме с помощью электродов электрических потенциалов сердца, их усиления и регистрации сигналов на термочувствительной бумаге по 12-ти общепринятым отведениям.

ECG 9620К/М воспринимает и записывает одновременно 6 отведений.

ECG 9320К воспринимает и записывает одновременно 3,6,12 отведений.

Электрокардиографы ECG 9620 К/М, ECG 9320К обеспечивают регистрацию данных в следующих режимах: автоматический, ручной, регистрация ритма.

В режиме автоматической регистрации автоматически выполняется анализ ЭКГ. После распечатки кривых ЭКГ автоматически печатаются результаты анализа ЭКГ. Режим автоматической регистрации может быгь двух типов. Первый — режим регистрации в реальном времени, второй — режим просмотра регистрации. В режиме просмотра регистрации вы можете проверить качество и точность анализа кривой ЭКГ, отображаемой на экране, перед тем, как запустить регистрацию. Во время автоматической регистрации, если обнаруживается аритмия, то ав

томатически может регистрироваться вывод ритма (вывод II) в течение 60 секунд (расширенная регистрация ритма при аритмии).

В режиме ручной регистрации можно вручную изменять установки регистрации (скорость протяжки бумаги, чувствительность и ВКЛ/ВЫКЛ низкочастотного фильтра EMG) в течение процесса регистрации.

В режиме регистрации ритма, перед или после автоматической или ручной регистрации кривых ЭКГ, вы можете записать 60 секунд отведения ритма (отведение II) в формате 3 трасс на двух страницах.

Электрокардиографы ECG 9620 К/М, ECG 9320К обеспечивают отображение на экране дисплея состояние программируемых параметров, режима работы, режима обследования, чувствительности, скорости записи, текущего значения ЧСС, текущего времени, состояния фильтров, калибровочного и ЭКГ-сигнгшов, введенных данных пациента.

Управление ЭКГ производится с помощью кнопок, расположенных на панели.

ЭКГ обеспечивают возможность пользователю изменять программные функции в зависимости от конкретного применения, а так же вводить с данные пациента (идентификационный номер, пол, возраст, вес, рост и т.д.).

ЭКГ снабжены сетевыми, миографическими фильтрами и фильтром дрейфа изолинии.

ЭКГ обеспечивают вывод на печать электрокардиограммы и результаты измерений.

Конструктивно ЭКГ состоит из основного блока, выносного блока с кабелем пациента и зарядного устройства.
