Abstract

The invention provides an integrative physical examination instrument for electrocardiogram detection and urinalysis, which relates to a medical appliance for the electrocardiogram detection and the urinalysis and aims to multiplex two conventional instruments by hardware to realize integration. Especially, a rubber roller of a miniature thermal printer drives a movement mechanism of a supporting board of test paper by means of frictional connection, a photoelectric sensor is successively aligned with a color lump of the urinalysis project test paper, an electrocardiogram signal analog amplifier is arranged on a main circuit board, six paths of electrocardiogram signals of the electrocardiogram signal analog amplifier are directly connected to the input ends A0 to A5 of an analog signal of a main microprocessor, the other two paths of electrocardiogram signals are connected to the input ends A6 and A7 of a multiplexing signal of the main microprocessor by the gating of an analog switch (103), a red-green-blue three-color LED luminotron (10) and a light-sensitive cell (13) are arranged on a circuit board (0) of the photoelectric sensor, photoelectromotive force which is generated by the light-sensitive cell and is relevant to the color change of the color lump of the test paper also enters multiplexing passages A6 and A7 by the gating of the analog switch, and the gating of the analog switch is controlled by a photoelectric sensing signal transmitted by an infrared photoelectric switch element (17) when the supporting board of the test paper is inserted at the position of a pole terminal.

Description

technical field [0001] The invention belongs to the field of medical devices, in particular to clinical medical detection equipment for electrocardiogram and urine analysis, and aims to provide a multifunctional digital detection equipment for basic medical care. technical background [0002] In primary medical care, the synchronous 12-channel ECG detection technology with intelligent analysis software and printed graphic reports is a new type of ECG detection mode respected by modern clinical medicine. The status is expressed simultaneously from the perspective of multi-phase observation, which overcomes the drawbacks that only one level of signal amplification channel is used in conventional ECG detection, and the signals of each lead are serially processed separately, and the observation of different myocardial parts cannot be carried out in the same myocardial beat. Obvious diagnostic advantages; urine is one of the most non-invasive body fluids obtained by the human bod...
