Detailed description of the invention
Fig. 1 is a kind of structural representation of the electromyogram evoked potentuial measuring system with double isolated power supplies of embodiment of the utility model
Figure.
Specific embodiment
The utility model is described in further detail below by specific embodiment combination attached drawing.
The utility model embodiment provides a kind of electromyogram evoked potentuial measuring system with double isolated power supplies, as shown in Figure 1, its
Including workbench 1, main body supporting structure of the workbench 1 as electromyogram evoked potentuial measuring system, top has for user's operation
Operation position is equipped with display 3 and preamplifier 4 on operation position.Display 3 is used to show testing result, preceding storing
Big device 4 is used as the amplification to electric potential signal, is the basic module in electromyogram evoked potentuial measuring system.It is fixed below the workbench
There is fixed case 2, stationary phase 2 has an insulation crust, has cavity in shell, fix control circuit and computer in the cavities
Host, control circuit can be the circuits such as the controller in existing electromyogram evoked potentuial measuring system, the preamplifier 4 and calculating
Machine host is connected with control circuit, and control circuit plays data calculating and processing function.The display 3 and main frame
It is connected, after collecting electric potential signal, is amplified by preamplifier 4, is then transmit to control circuit, control circuit warp
After crossing calculating, corresponding testing result is obtained, and result is output to main frame, it is defeated that main frame controls display 3
Corresponding testing result out.Be additionally provided with two independent power supplies in the fixed case 2, two power supplies respectively with control
Circuit is connected with main frame, to power respectively to control circuit and main frame.
In one embodiment, the power supply includes power circuit, filter circuit, the surge protection electricity being sequentially connected
Road and isolating transformer.It, can will be in power supply by filter due to the harmonic wave and electromagnetic interference in power supply signal there are many frequency point
These unnecessary interference filter out, to obtain more pure power supply.When in electric loop or communication line because
When extraneous interference generates peak current or voltage, shunting can be connected in surge protection circuit in a very short period of time, to avoid
Damage of the surge to equipment.Electromyogram evoked potentuial measuring system does not use network source alternating current directly, uses isolating transformer and carries out
Protection isolation.On the one hand from not having potential difference between security consideration, isolating transformer and the earth, people contacts any one line
It will not get an electric shock, relatively safety.Secondly, the output of isolating transformer and input terminal are complete breaking isolation designs, effectively filter
The interference that network source is come, to provide purer supply voltage for instrument.
Wherein, the power circuit is external alternating current, and electromyogram evoked potentuial measuring system comes with attaching plug, can pass through electricity
Source plug is electrically connected with city, thus using alternating current as original power.
In one embodiment, the outside mask of the fixed case 2 is equipped with shielding case, which can shield external letter
Number interference, further enhance the anti-interference ability of electromyogram evoked potentuial measuring system.Wherein, it for the ease of internal heat dissipating, can shield
Heat release hole is opened up on cover.Above-mentioned shielding case can be by multipoint earthing and the earth intercommunication, to make extraneous next interference from shielding
Cover is introduced directly into the earth, can not have an impact to system itself.
In one embodiment, as shown in Figure 1, the workbench 1 includes pedestal 11, the pedestal 11, which is equipped with, vertically to be prolonged
The multiple support rods 12 stretched, the top of support rod 12 are fixed with fixed plate 13.Display 3 is then fixed in fixed plate 13, fixed
Case 2 is then fixed on 13 lower section of fixed plate.It is additionally provided with idler wheel under pedestal 11, to be moved easily entire electromyogram evoked potentuial measuring system.
In one embodiment, the lower section of the workbench 1 is equipped with printer 5, the printer 5 and main frame phase
Even, corresponding testing result can be printed by printer 5.
In one embodiment, the workbench 1 is equipped with keyboard, the keyboard be it is plug-type, may be collapsed to solid
