Description
Technical field
The utility model relates to a kind of fault locator, particularly relates to a kind of multi-functional electrocardio quasi-instrument line fault locator that leads.
Background technology
Instrument application clinically such as electrocardiograph, ECG monitor, electroence phalograph in recent years are very extensive, and each hospital is with regard to this kind equipment hundreds of platform at most, tens at least.Because these instruments in use all need to directly act on by the line that leads on it corresponding site of human body, to extract feeble signals such as electrocardio, brain electricity, then this signal is amplified, analyzes, demonstrate cardiogram, electroencephalogram at last and print the result.State in the use in these instrument processes, the line that leads will inevitably contact with human body, thereby giving emergency treatment to a patient act hurriedly in a messy situation in or under the situation such as patient generation itself is restless, the line that leads will constantly produce stretches, draws, drags phenomenon, thereby the failure rate of the line that causes leading is very high.Line breaks down and will cause the serious interference of electrocardio, brain electricity in case lead, and the result makes the output waveform distortion, even does not have waveform output, will have a strong impact on clinical diagnosis, rescue and treatment like this.
When the line that leads breaks down, repair very trouble, this is because the line that leads is a shielded multiconductor cable of being drawn by the plug that links to each other with main frame, is divided into many single cores then and shields branch and lead behind the line, again joint detection electrode and forming separately.Because the interface on the plug is of all kinds, for example pin type, needle stand formula etc., and the line that leads that has does not contact with multitester probe at all, such once personal multimeter measurement search the trouble spot especially the difficulty, and the line that tens leads need be measured one by one, so not only time-consuming but also effort, thereby work efficiency is relatively low, and measurement result is very inaccurate.
Summary of the invention
In order to address the above problem, the purpose of this utility model is to provide a kind of simple and efficient to handle and multi-functional accurately electrocardio quasi-instrument of measurement result line fault locator that leads.
In order to achieve the above object, the multi-functional electrocardio quasi-instrument that provides of the utility model line fault locator that leads comprises housing and the input part that is connected with each other by lead, lead selection portion, control part, power supply unit and display part; Wherein input part is installed on the end face of housing, and it is made up of a plurality of different types of Interface Terminals and a plurality of different types of connection terminal; The lead selection portion is made up of one group of selector switch that is installed on the housing end face, is used to select the line that leads to be measured; Control part is installed in the inside of housing, and it can detect the selected line that leads automatically, and sends testing result to display part; Power supply unit is arranged on the inside of housing, and it can convert low-voltage DC to offer other each one after using the voltage stabilizing of 200V AC rectification always; Display part is made up of normal display part, broken string display alarm portion and shorted to earth display alarm portion, its can demonstrate respectively according to the signal that control part transmits lead line normally, broken string and three kinds of information of shorted to earth.
Broken string alarm device and the short circuit alarm device that can sound also are installed on the described housing.
Under the line normal condition of leading, display part is lighted the normal display lamp that is arranged on the housing end face.
Under the line broken string situation of leading, display part is lighted the broken string display lamp that is arranged on the housing end face, sends the broken string alerting tone by the broken string alarm device simultaneously.
Under the line shorted to earth situation of leading, display part is lighted the shorted to earth display lamp that is arranged on the housing end face, sends the shorted to earth alerting tone by the shorted to earth alarm device simultaneously.
Described housing is formed with ventilation window on the side, but also exhaust fan is installed.
Every of leading that the line fault locator can detect needs of the multi-functional electrocardio quasi-instrument that the utility model provides lead whether line is normal, broken string or shorted to earth situation detect immediately, and the trouble spot analyzes accurately, so work efficiency is higher relatively.In addition, owing to which is provided with a plurality of different types of Interface Terminals and a plurality of different types of connection terminal, so applicable scope is wide, and safe and reliable.
