Description
Technical field
The utility model relates to the field of medical instrument technology, especially a kind of split type anti-jamming myoelectricity figure Evoked ptential
Instrument.
Background technique
Electromyogram evoked potentuial measuring system is the special instrument for detecting human body electro physiology, will by high-precision preamplifier
The biopotential signals of human body are acquired into system, then carry out the post-processing of Bioelectrical Wave, so determine neuromuscular system and
Whether the function of central nervous system is normal.
The as low as 0.05uV of signal detected by potentiometer is extremely small electric potential signal greatly to 20mV, in order to full
Foot can detect small-signal and detect the requirement of the most strong bioelectrical signals of human body, need system sensitive enough.And sensitive meaning
Taste then means more easily then to be influenced inspection result by extraneous interference.Traditional anti-interference mode is to require detection work
Work must be carried out in the case where shielding room environmental, and purpose is exactly to reduce from extraneous interference.But for many users, and
There is no condition to establish screened room, this just needs electromyogram evoked potentuial measuring system itself to have extremely strong anti-interference ability.
Utility model content
The utility model provides a kind of split type anti-jamming myoelectricity figure evoked potentuial measuring system, by control module and main frame
Module is separated and is shielded, and promotes the anti-interference ability of electromyogram evoked potentuial measuring system.
A kind of split type anti-jamming myoelectricity figure evoked potentuial measuring system, including workbench, the workbench be equipped with display and
Preamplifier, the workbench lower section are fixed with fixed case, the control cabinet and meter being separated from each other are provided in the fixed case
Machine host to be calculated, is equipped with control circuit in the control cabinet, the preamplifier and main frame are connected with control circuit,
The display is connected with main frame.
Preferably, the control cabinet has the first shielding case, and the main frame has secondary shielding cover.
Preferably, the outside mask of the fixed case is equipped with third shielding case.
Preferably, the workbench includes pedestal, and the pedestal is equipped with vertically extending support rod, on the support rod
It is fixed with fixed plate.
Preferably, the lower section of the workbench is equipped with printer, and the printer is connected with main frame.
Preferably, the workbench is equipped with keyboard, and the keyboard is connected with main frame.
In the utility model, control circuit and main frame are separated from each other, make medical electric part and computer portion
Divide and be integrated in different cabinets respectively, reduces the signal interference of electromyogram evoked potentuial measuring system, improve electromyogram Evoked ptential
The anti-interference ability of instrument.
Detailed description of the invention
Fig. 1 is a kind of structural schematic diagram of the split type anti-jamming myoelectricity figure evoked potentuial measuring system of embodiment of the utility model；
Fig. 2 is a kind of structural schematic diagram of the secondary shielding cover of embodiment of the utility model.
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 split type anti-jamming myoelectricity figure evoked potentuial measuring system, as shown in Figure 1 comprising
Workbench 1, main body supporting structure of the workbench 1 as electromyogram evoked potentuial measuring system, top have the operation for user's operation
Station is equipped with display 3 and preamplifier 4 on operation position.Display 3 is used to show testing result, preamplifier 4
It is the basic module in electromyogram evoked potentuial measuring system as the amplification to electric potential signal.It is fixed with below the workbench
Determine case 2, stationary phase 2 has an insulation crust, has cavity in shell, be fixed in the cavities the control cabinet being separated from each other and
Main frame, control cabinet and main frame are spaced from each other a distance, so that the two is not interfered each other.In the control cabinet
Interior to be equipped with control circuit, control circuit can be the circuits such as the controller in existing electromyogram evoked potentuial measuring system, put before described
Big device 4 and main frame are connected with control circuit, and control circuit plays data calculating and processing function.The display 3
It is connected with main frame, after collecting electric potential signal, is amplified by preamplifier 4, is then transmit to control electricity
Road, control circuit obtain corresponding testing result, and result is output to main frame, main frame after calculating
Control display 3 exports corresponding testing result.
In one embodiment, as shown in Fig. 2, the control cabinet has the first shielding case, the main frame has
Secondary shielding cover 21.First shielding case and secondary shielding cover 21 may each be the shell of cabinet, or added on cabinet
Shielding case.Two shielding cases will further decrease the signal interference of electromyogram evoked potentuial measuring system inside itself, promotes electromyogram and lures
Send out the anti-interference ability of potentiometer.
Further, the outside mask of the fixed case 2 is equipped with third shielding case, which can shield external
Signal interference further enhances the anti-interference ability of electromyogram evoked potentuial measuring system.
Wherein, machine host radiates for ease of calculation, and heat release hole 22 can be opened up on secondary shielding cover 21.Above-mentioned shielding
Cover can by multipoint earthing and the earth intercommunication, thus make it is extraneous come interference be introduced directly into greatly from shielding case, can not be to system
Itself has an impact.
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
13 lower section of fixed board.The keyboard is connected with main frame, provides the channel of human-computer interaction, user-friendly.
The above content is combine specific embodiment further detailed description of the utility model, and it cannot be said that
The specific implementation of the utility model is only limited to these instructions.For the utility model person of an ordinary skill in the technical field
