The three-way signal processing unit comprises a first channel signal processing unit, a second channel signal processing unit and a third channel signal processing unit. One unit of the three-way signal processing unit is a multipath matrix spatial overlap signal processing unit, while the other two units of the three-way signal processing unit are both bipolar input signal processing units. All the channel signal processing units are led into the A / D converter through the sampling maintenance unit and then are led into the computer unit through the A / D converter for being processed. The input electrode of the multipath matrix spatial overlap signal processing unit is an array type electrode.

Description
Technical field
This utility model relates to the electrocardiographic recorder system, especially triple channel demultiplexing matrix formula space stack cardiac electricity detecting system.
Background technology
Routine electrocardiogram recording technique in the past be mainly used in record " millivolt level " and electrocardiosignal can write down 12 electrocardiosignaies of leading according to the difference of normal electrode rest, employing be the real time record technology.The method that employing time stacking method record " microvolt level " signal is also arranged is promptly got the electrocardiosignal in different time cycle, judges that through software the signal in the effective cycle superposes, and its shortcoming is to lose useful signal, or makes signal distortion.But can record " microvolt level " signal that can not write down after all over, such as: can write down VLP, sinus node potential etc., but can not write down his' bundle potential, because of it is a high-frequency signal, possibly offset part signal during stack.And imagination adopts the synergetic method in space to remedy the deficiency of time stacking method in the past; Though but the space superimposing technique in past is to the stack with the one-period electrocardiosignal; But because the distribution of electrodes that adopts is too wide in body surface, distribution; The electrocardiosignal waveform is different between each electrode, so the electrocardiosignal that superposes out still has distortion, this distortion is because same cardiac electrical cycle and different distribution of electrodes position causes; And the distortion of the signal in when stack time produces owing to different cardiac electrical cycle, though both differences all have signal distortion.
Summary of the invention
In order to solve the shortcoming of prior art; This utility model technology provides a kind of triple channel demultiplexing matrix formula space stack cardiac electricity detecting system, can solve because of the signal distortion that the different distribution of electrodes of same cardiac electrical cycle position is different, the same distribution of electrodes of different cardiac electrical cycle produces.
This utility model solves the technical scheme that relevant issues adopted: triple channel demultiplexing matrix formula space stack cardiac electricity detecting system; Its difference is: comprise triple channel signal processing unit, sample holding unit, A/D converter, computer unit, said triple channel signal processing unit comprises first passage signal processing unit, second channel signal processing unit, third channel signal processing unit; A unit in the said triple channel signal processing unit is a demultiplexing matrix space superposed signal processing unit, and other 2 unit are bipolar input signal processing unit; Each channel signal processing unit gets into A/D converter through sample holding unit; Sending into computer unit by A/D converter again handles; The input electrode of said demultiplexing matrix space superposed signal processing unit is an array-type electrode, is parallel with the series circuit of multirouting photoelectric isolating circuit, high-pass filtering circuit, gain control circuit formation between the circuit link of array-type electrode and the sample holding unit.
By above scheme, said bipolar input signal processing unit comprises placed in-line successively bipolar signal input equipment, photoelectric isolating circuit, high-pass filtering circuit, gain control circuit.
By above scheme, said array-type electrode comprises the circuit board matrix, and the end face of circuit board matrix is densely covered with many and is the metal probe that array is arranged.
By above scheme, said circuit board matrix has a plurality of plated through-holes that are used to install metal probe, and the arrangement pitches of plated through-hole is 1-3mm, and the circuit board matrix thickness is 1.5-2 mm.
By above scheme, the outer bore dia of said plated through-hole is 1.2-1.8 mm, and diameter of bore is 0.2-0.35 mm.
By above scheme, said circuit board matrix is a double-layer circuit board.
The contrast prior art; The beneficial effect of this utility model is: this utility model can be the multichannel electrocardiosignal when one tunnel processing; That is: the input electrode of demultiplexing matrix space superposed signal processing unit is an array-type electrode; Because the signal input point accumulates in (being in the array electrode scope) in the certain little subrange; With respect to the record that carries out of a certain reference point, to the stack of the spacing wave in this array electrode scope, the noise of each road amplifier is different but each the road electrocardiosignal waveform in this array electrode scope is identical; Thereby can be superimposed as one road microvolt level electrocardiosignal by multiple signals relative through array electrode and reference point, cooperate several roads body surface " millivolt level " electrocardiosignal to form multiple tracks electrocardiosignal detection system again.The maximum difference of this system and common system is to have in the multi channel signals passage can real time record " microvolt level " electrocardiosignal, so just can realize the purpose of body surface measurement " microvolt level " electrocardiosignal, is convenient to carry out the research of electrocardiosignal details.
