Medical Equipment Hospital Equipment 32 channel Digital EEG Machine Mapping System
Features
1.Standard 32 leads of EEG. Method of 10/20 electrodes placement under international standard system, can change leads ways while real-time playing or replaying. Supporting sorts of lead mode, such as Al, A2, A1+A2, A1A2, BN, CZ, user-defined, and so on.
2.Using bioelectricity amplifier brainwave, consecutive record time can be up to 24 hours, integrated automatic calibration system.
3.Powerful playback function: It is adjustable for the amplitude and replaying rate. The special subdividing time line divides the waveform in one second into 5 parts and easy for the doctors to look over the waveform.
4.Multifunctional digital filter system can be set freely and provides many filtering methods.
5.EEG signal clipping function,clipping any a section of EEG wave to analyse and store, clipping multi-section waves to perform multi-parameter analyse and pick-up automatically.
6.Electronic frequency ruler, convenient to measure the basic information of any appointed EEG waves. 7.Sectional enlargine window, which can be adjusted by yourself, is provided to increase the accuracy of EEG period /amplitude /frequency measurement.
8.Mark event (openning eyes, closing eyes and flashing) EEG with different colors, and name the user-defined event. Color of background and waveform occurred by different event is adjustable. It is able to depend on the event's name to locate speedily the waveform of the corresponding time.
9.Powerful automatic analyse function, can carry through the power spectrum analyse and pathologic wave detection for appointed waveform. Sorts of graph can be displayed in the same screen, including kinds of BEAM, numerical BEAM, compressed spectrum graph, trend graph, and so on.
10.Professional isolation transformer, dual power supply isolation system and optoelectronic data transmission to ensure security. Use USB interface to transmit data which just need to be inserted. 11.Distance of digital signal transmission is up to a maximum of 30 meters. Patients and doctors can be operated in different rooms.
12.Multifunctional flashlight of USB interface, and frequency can be controled manually or automatically. 13.A flashlight stimulus scheme can be set and performed in the process of collection.
14.Perfect case management, multi-method of information query and quick statistics means, convenient case input and output function, supporting MO or CD-RW store, which is easy for data research.
15.The report of picture and character integration, can be edited in mode and changed into Word.
16.The case can be transfromed into the EDF data format, which is convenient for the data interchange, academic exchanges and further analyse.
17.System setup function, multi-function, such as display mode, system parameters, etc., can be set to meet the users' special need.
18.Mark positioning function: add the mark and note for the waveform of appointed time, and locate speedily the waveform at the mark time.
19.Optional video function: USB CCD camera is easy to install, convenient to use and exact to record. With agile playback function, it can be used to replay the waveform of any time along with the corresponding isochronous collected image.
20.SpO2 function is optional.
