Abstract
The utility model discloses an electrocardiograph (ECG) monitor which comprises an ECG sensor, a signal amplifier, a filter circuit, an A/D converter, an optoelectronic isolation circuit, a master control circuit, a storer read only memory (ROM) and a serial data conversion module. The ECG sensor, the signal amplifier, the filter circuit, the A/D converter, the optoelectronic isolation circuit and the master control circuit are sequentially in series connection. The storer ROM and the serial data conversion module are in parallel connection with the master control circuit. Through multiple times of noise reduction and filtering processing, the ECG monitor achieves the characteristic of high impedance. The storer is connected with a remote monitor through a modem and a telephone line or through a network, and the purpose of remote control is achieved.
Description
Technical field
This utility model relates to a kind of armarium, particularly a kind of electrocardiogram monitor.
Background technology
Investigation shows, cardiovascular disease has become one of principal disease of present threat human life, and the main cause that causes this type of disease is that people's rhythm of life is accelerated, population gradually aging and life erratic behavior.The main feature of cardiovascular disease is sudden, transience and danger, if can not in time find and treat, will have serious consequences to the patient.
Electrocardiogram monitor is important means and the foundation that checks, diagnoses and prevent such disease, is an important instrument of monitoring patients heart state, and for symptoms such as myocardial infarction, arrhythmia, the use of electrocardiogram monitor is through the whole process for the treatment of, rehabilitation.Because traditional electrocardiogram monitor based on the PC platform is expensive, bulky, be not easy to move and mainly concentrate on large hospital, brought very large inconvenience for doctor and patient.
Summary of the invention
But the technical problem that this utility model solves provides the electrocardiogram monitor of a kind of high resistant resistance remote monitoring.
For achieving the above object, electrocardiogram monitor of the present utility model adopts the technological means of repeatedly electrocardiosignal being carried out denoising, filtering, and adopts modem or network means, thereby but realizes that the high resistant resistance reaches the purpose of remote monitoring.
A kind of electrocardiogram monitor that this utility model relates to, comprise EGC sensor, signal amplifier, filter circuit, A/D converter, total control circuit, memorizer ROM, serial data modular converter, described EGC sensor, signal amplifier, filter circuit, A/D converter and total control circuit are connected in series successively, described memorizer ROM and serial data modular converter are connected in parallel on the total control circuit, it is characterized in that: it also comprises photoelectric isolating circuit, between A/D converter and total control circuit, connect with series system.
A kind of electrocardiogram monitor that this utility model relates to is characterized in that: described memorizer passes through mediation demodulation device and telephone wire, or links to each other with the long distance monitoring device by network.
A kind of electrocardiogram monitor that this utility model relates to is characterized in that: described signal amplifier comprises preamplifier, band filter and main amplifier.
A kind of electrocardiogram monitor that this utility model relates to is characterized in that: described filter circuit (3) comprises 50Hz, 35Hz wave trap and low-pass filter circuit.
Electrocardiogram monitor of the present utility model has realized the purpose of high resistant resistance by technological means such as employing band filter, filter circuit and photoelectric isolating circuits, and adopts modem or network means, has realized the purpose of remote monitoring.
Description of drawings
What Fig. 1 represented is the formation schematic diagram of this utility model electrocardiogram monitor.
Wherein, 1-EGC sensor, 2-signal amplifier, 3-filter circuit, 4-A/D transducer, 5-photoelectric isolating circuit, 6-total control circuit, 7-memorizer ROM, 8-serial data modular converter.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, the technical solution of the utility model is described in further detail.
As shown in Figure 1, electrocardiogram monitor of the present utility model comprises EGC sensor 1, signal amplifier 2, filter circuit 3, A/D converter 4, photoelectric isolating circuit 5, total control circuit 6, memorizer ROM7, serial data modular converter 8.
Described signal amplifier 1 comprises preamplifier, band filter and main amplifier; Described filter circuit 3 comprises 50Hz wave trap, 35Hz wave trap and low-pass filter circuit.
Delivered in the signal amplifier 2 through conducting wire by the electrocardio road signal that EGC sensor 1 obtains, at first entering front back of the body amplifier tentatively amplifies, various interfering signals are carried out sending into band filter after to a certain degree the inhibition, interfering signal beyond the filtering electrocardio frequency range, main amplifier further is amplified to OK range with filtered signal again; Send into subsequently filter circuit 3, wave trap filtering power frequency and myoelectricity via 50Hz and 35Hz disturb, signal is sent in the low pass filter subsequently, the cut-off frequency of low pass filter is set to 80Hz to 1kHz, so that induction brings the interfering signal of upper frequency by filtering in the high-frequency noise that signal amplifier 1 is introduced and the human body, signal is sent in the A/D converter 4, be analog signal conversion digital signal, deliver to subsequently in the photoelectric isolating circuit 5, carry out further denoising and the filtering of electrocardiosignal, these signals are through total control circuit 6, be admitted among the memorizer ROM7 and store, through modem and telephone wire, perhaps arrive the long distance monitoring device by network delivery, thereby realize the purpose of remote monitoring; Signal through photoelectric isolating circuit 5 further denoisings and filtering also can enter serial data modular converter 8 by total control circuit 6, shows by printer or the computer that links to each other with serial data modular converter 8 at last.
