Abstract
A palm-type electrocardiogram instrument for preventing heart disease generation is composed of a casing, an internal electrocardiac signal processor consisting of differential amplifier, filter, A/D converter and microprocessor, two plate electrodes, display screen, power supply and operating buttons.
Description
Technical field
The present invention relates to a kind of medical monitoring device, be specifically related to a kind of portable mini-electrocardiograph.
Background technology
General electrocardiograph need just can obtain human ecg signal by lead line and human body limb or pareordia contact skin with battery lead plate, yet the operation of this electrocardiograph is very complicated, and needs the professional to carry out electrocardiographic recording.
Can grasp self heart body situation at any time for ease of people, it is for people to use that medical apparatus and instruments producer produces portable electrocardiograph.Disclose a kind of portable electrocardiograph as Chinese patent 200410104863, this portable electrocardiograph is the outer surface that the 1st electrode is arranged at apparatus main body, and the 2nd electrode is drawn to the apparatus main body outside from apparatus main body by connection cord, by the potential difference that produces between two electrodes of measuring contact surface (mainly being between patient's the hands and chest), can the instrumentation ecg wave form.Thus, the myoelectric potential that is produced by the muscle beyond the cardiac muscle can not become noise and on the ecg wave form that is added to, thus high accuracy instrumentation ecg wave form stably comparatively.Yet the weak point of this portable electrocardiograph is to use connection cord, and this gives to use and carry and brings some inconvenience; And, since the human body surface of electrode contact be need exposed, this also make the patient can not be easily the ecg wave form of instrumentation oneself quickly, especially colder at weather, wear clothes more in.
Chinese patent 200410059061 also discloses a kind of portable electrocardiograph, and it all is arranged on two electrodes on the housing, has exempted the trouble of using connection cord; And counter electrode and human body electrodes in contact formation face improve, and made things convenient for people's use to a certain extent.Yet it in use still needs hands to contact and can test with two electrodes respectively with exposed trunk position (as chest and abdominal part), and this also makes troubles to use undoubtedly.
Summary of the invention
The objective of the invention is at the problems referred to above, provide a kind of need both hands to hold and get final product the high accuracy mini-electrocardiograph of instrumentation ecg wave form stably.
For achieving the above object, technical scheme of the present invention is as follows: mini-electrocardiograph, one housing is arranged, device electrocardiosignal treatment circuit and power supply in the housing, battery lead plate, display screen and operation push-button are set on the housing, and the electrocardiosignal treatment circuit comprises amplifier, wave filter, analog-digital converter and microprocessor; Described battery lead plate is two, is arranged at the left and right sides of housing respectively; And described amplifier is a difference amplifier, housing right electrodes plate is connected with the input negative pole of difference amplifier, housing left electrodes plate is connected with the input positive pole of difference amplifier, and two resistance that are no less than 2.5M Ω of series connection between the input positive and negative electrode of difference amplifier, the ground wire of difference amplifier is connected between two resistance.
Above-mentioned housing is provided with a three-plug connector for the line or the transducer that the leads connection of leading, and the input positive pole of difference amplifier, input negative pole and ground wire go between respectively and be connected in this three-plug connector.
Above-mentioned electrocardiosignal treatment circuit comprises a bin, and this bin is connected with microprocessor.
Above-mentioned housing is provided with an interface for outside storage medium connection, and this interface is connected with the outfan of microprocessor.
Above-mentioned microprocessor is one to include the microprocessor of the automatic analysis software of ecg wave form.
The present invention is by adopting said structure, the operator only needs to hold the present invention with the right hand makes right hand palm skin contact with housing right electrodes plate, with housing left electrodes plate and left hand palm skin (also can contact with left lower extremity or pareordia skin), the present invention just can obtain electrocardiosignal from human body simultaneously.The present invention makes the general personage who was not subjected to the medical speciality training under the situation that needs hardly to learn, and can both carry out electrocardiographic recorder whenever and wherever possible, and then the effectively generation of prevention of cardiac.
