Description
Technical field
The utility model relates to a kind of signal connecting line, particularly relates to a kind of medical equipment signal connecting line of anti-electromagnetic interference.
Background technology
In medical equipment field, often use signal connecting line each equipment is connected, then the signal transmission between each equipment is realized, because medical equipment in use requires that control precision is high, therefore the anti-interference requirement for signal connecting line is also just very high, malpractice is caused to prevent extraneous electromagnetic interference, especially the surgical apparatus of human body is directly acted on, such as act on the bone drill of human body, on off control for bone drill is realized by a control switch (generally adopting foot switch), then by connecting line, bone drill is connected the transmission realizing control signal with control switch, if the shielded signal scarce capacity of signal connecting line, so extraneous electromagnetic signal will directly act on connection line, thus cause the control precision successful implementation of impact operation not on bone drill, even cause malpractice, Medical Devices again such as monitoring, if the shielding of holding wire is bad, so directly will have influence on check result, and then have influence on the accuracy of diagnosis.
For solving the problem, existing signal connecting line is generally provided with screen, when there is electromagnetic interference in the external world, Electromagnetic Field can produce vortex flow in screen inside after screen, after the existence of vortex flow, so screen to generate electromagnetic waves and then act on equally on core and produce vortex flow on core, core is caused to make the electric current exported increase when transmitting and controlling electric current, that is the electromagnetic interference in the external world only weakens by existing signal connecting line, can not eliminate the impact on the core in Signal transmissions.
Therefore, be necessary the signal connecting line that a kind of novel medical equipment is provided, effectively can shield extraneous electromagnetic interference to the impact of Signal transmissions, and the electromagnetic impact that screen produces due to vortex flow can be eliminated, improve the control precision of medical equipment and the accuracy of diagnostic result.
Utility model content
In view of this, the purpose of this utility model is to provide a kind of medical equipment signal connecting line of anti-electromagnetic interference, effectively can shield extraneous electromagnetic interference to the impact of Signal transmissions, and the electromagnetic impact that screen produces due to vortex flow can be eliminated, improve the control precision of medical equipment and the accuracy of diagnostic result.
The medical equipment signal connecting line of a kind of anti-electromagnetic interference that the utility model provides, at least comprises the core for signal transmission and the screen that is wrapped in outside core, and described core is by filter unit ground connection.
Further, described filter unit is near the signal output part of core.
Further, the signal input part of described core and signal output part are all by corresponding filter unit ground connection.
Further, described filter unit is electric capacity.
Further, described shielding layer grounding.
Further, the signal input part of described screen and core and the equal ground connection in two ends corresponding to signal output part.
Further, described screen is enclosed with insulating barrier.
The beneficial effects of the utility model: medical equipment signal connecting line of the present utility model, adopt mode heart yearn being arranged to filtering ground connection, interference signal outside electromagnetic interference produced is filtered to be derived, the equipment to core and its control is avoided to have an impact, greatly can strengthen the effect of anti-electromagnetic interference, avoid the impact that electromagnetic interference controls medical equipment, ensure result for the treatment of, and structure is simple, easily manufactured.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further described:
Fig. 1 is structural representation of the present utility model.
Embodiment
Fig. 1 is structural representation of the present utility model, as shown in the figure, the medical equipment signal connecting line of a kind of anti-electromagnetic interference that the utility model provides, at least comprises the core for signal transmission and the screen 2 that is included in outside core 3, and described core 3 is by filter unit ground connection, screen generally adopts conductor (metal) screen, when there is electromagnetic interference in the external world, first act on screen, due to galvanomagnetic effect, the inside of screen will produce eddy current, by generation two kinds of effects after eddy current produces: one is the thermal effect of screen, two is galvanomagnetic effects, that is eddy current can continue produce weak electromagnetic wave and then have influence on core further, core is caused to produce eddy current, thus the electric current causing core to pass through when equipment runs increases, and then affect the control of equipment and final treatment results, therefore, by structure of the present utility model, the galvanomagnetic effect that eddy current produces is by filter element filtering, the interference signal that elimination external electromagnetic signal produces is on the impact of core, greatly strengthen the effect of anti-electromagnetic interference, avoid electromagnetic interference to the interference of medical equipment control precision, improve the accuracy of diagnosis.
In the present embodiment, described filter unit, near the signal output part of core, by this structure, can ensure the noiseless of the control signal outputting to target device, and then ensures the control precision of application device and final result for the treatment of.
In the present embodiment, the signal input part of described core and signal output part are all by corresponding filter unit ground connection, described filter unit is electric capacity C, pass through said structure, the filter capacitor at core self and two ends thereof is made to form pi type filter, the vortex flow that can produce on core in input and output filtering simultaneously, thus control signal there will not be any change to make medical equipment ensure in running, the control precision of guarantee equipment and the accuracy of last diagnostic result, and then avoid the generation of malpractice; And said structure can't increase volume and the weight of signal connecting line entirety, easy to use.
In the present embodiment, described screen 2 ground connection, due to can vortex flow be produced when electromagnetic interference signal acts on screen, then include thermal effect in the effect of vortex flow, and then the temperature of screen is raised, can have an impact to the control precision of equipment equally, therefore, by by shielding layer grounding, the vortex flow major part that screen produces will be exported, thus substantially reduce the thermal effect of vortex flow.
In the present embodiment, the signal input part of described screen 2 and core 3 and the equal ground connection in two ends corresponding to signal output part, by this structure, can ensure that most of vortex flow is exported from screen, weaken the thermal effect of vortex flow, strengthen the effect of screen anti-temperature rise, and can not increase the volume of the entirety of signal connecting line and weight, easy to use.
In the present embodiment, described screen 2 is enclosed with insulating barrier 1, can effectively protect core and screen, the more important thing is the generation that effectively can prevent contingency.
What finally illustrate is, above embodiment is only in order to illustrate the technical solution of the utility model and unrestricted, although be described in detail the utility model with reference to preferred embodiment, those of ordinary skill in the art is to be understood that, can modify to the technical solution of the utility model or equivalent replacement, and not departing from aim and the scope of technical solutions of the utility model, it all should be encompassed in the middle of right of the present utility model.
