Abstract
The invention provides an electronic sphygmomanometer which can point out the reliability of blood pressure measurement results. The electronic sphygmomanometer consists of an inflation gasbag (3), hoses (2) and (5), a manipulator (4), a loudspeaker (6) and a digital display (1). The digital display (1) comprises a shell and a built-in circuit system, wherein the inner side of the inflation gasbag (3) is provided with two measuring terminals (7), and the distance between two poles of the measuring terminals is 2 cm. When electronic sphygmomanometer measures the blood pressure of a human body,the measuring terminals together with the inflation gasbag cling to the human body, so as to transmit a sensed skin resistance value to the input end of a resistance sensing unit of the built-in circuit system through a voltage form; the output end of the resistance sensing unit transmits data to an analog-digital conversion pin of a single chip microcomputer; the reliability of the blood pressure is judged through the data processing of the single chip microcomputer; a result is transmitted to a display unit and a voice unit; and the reliability of the current blood pressure is displayed andis pointed out through the loudspeaker (6) controlled by the voice unit.
Description
Technical field
The present invention relates to a kind of electric sphygmomanometer, specifically, relate to and a kind ofly can detect whether believable electric sphygmomanometer of blood pressure measurement.
Background technology
The use of electric sphygmomanometer is very universal, relevant patented technology is also many, be that 200620104374.9 described " numeral shows manual intervention formula electric sphygmomanometer " were exactly wherein a kind of relatively typically as the patent No., its weak point is the same credibility that can't determine measured blood pressure with other sphygomanometer, because impressions such as human blood-pressure is very easily looked, listened, pain stimulate and the influence of anxious state of mind.
Summary of the invention
The invention provides a kind of electric sphygmomanometer that can point out the blood pressure measurement credibility, overcome the deficiency of above-mentioned patent, principle is: body look, listen, impression such as pain stimulates and during anxious state of mind, blood pressure can raise, the skin resistance of this moment can reduce, changes in resistance can reflect the fluctuation situation of blood pressure indirectly, and then the credibility of definite institute measuring blood pressure, according to this principle, the present invention has carried out perfect to above-mentioned patent, design an energy when measuring human blood-pressure by the sensing skin resistance, determine whether believable sphygomanometer of this blood pressure measuring value.
For realizing above-mentioned technical purpose, the present invention by gas cell, flexible pipe and, operator, speaker and character display form, character display comprises shell and built-in circuit system.There are two calibrating terminals the inboard of wherein said gas cell, distance between calibrating terminal the two poles of the earth is 2CM, when measuring human blood-pressure, measurement terminal is close to human body together with gas cell, the skin resistance value that sensing is obtained is delivered to the input of the resistance sensing unit of built-in circuit system with the form of voltage, the analog digital conversion pin of single-chip microcomputer delivered to data by the outfan of resistance sensing unit, judge the credibility of blood pressure by the date processing of single-chip microcomputer, the result is delivered to display unit and voice unit, show that the credibility of current blood pressure and the speaker of controlling by voice unit send prompting.
The calibrating terminal of the resistance sensing unit of internal circuitry links to each other with colelctor electrode with the base stage of audion by resistance, slide rheostat VR1 links to each other with the base stage of audion T1BC548, be used for the average resistance of regulating circuit to the human body relaxed state, slide rheostat VR2 links to each other with the emitter stage of audion T1BC548, and the output signal of slide plate directly links to each other with the digital-to-analogue conversion pin of control single chip computer.
The present invention will be illustrated by specific embodiments and the drawings subsequently.
Beneficial effect:
When measuring human blood-pressure, the influence of consider to look, listen, keenly feel irriate and anxious state of mind can learn by demonstration and voice suggestion whether the current pressure value that records is credible.

The specific embodiment
The present invention improves to form on the basis of prior art numeral demonstration manual intervention formula electric sphygmomanometer, described prior art numeral shows that the design of manual intervention formula electric sphygmomanometer sees Chinese patent for details and invents 200620104374.9 description CN2930612 " numeral shows manual intervention formula electric sphygmomanometer ", below mainly introduces the present invention and the design partly of its difference.
In Fig. 2, by gas cell 3, flexible pipe 2 and 5, operator 4, speaker 6, calibrating terminal 7 and internal circuit 1 are formed, more than the surveying instructions of composition and blood pressure mainly contrasts invention 200620104374.9 description CN2930612 " numeral shows manual intervention formula electric sphygmomanometer " Fig. 1, main change is: increased speaker and be close to two measurement terminal 7 on the inwall of gas cell 3, when measuring blood pressure, measurement terminal 7 is delivered to the skin resistance value input of the resistance sensing unit of internal circuitry with the form of voltage signal, the analog digital conversion pin of single-chip microcomputer delivered to data by the outfan of resistance sensing unit, carry out date processing by the resistance value scope that pre-sets in the single-chip microcomputer, the result is delivered to display and voice unit, display display of blood pressure value shows credible or insincere simultaneously.The speaker of voice unit control sends two kinds of indications, and indication 1: the pressure value that you record is credible; Prompting 2: you are in tension, please survey after a while again.
In Fig. 3, internal circuitry has increased resistance sensing unit 10 and voice unit 8.The skin resistance value that calibrating terminal senses is delivered to resistance sensing unit 10 with the form of voltage signal, and the analog digital conversion pin of single-chip microcomputer 9 is delivered in the amplification of process resistance sensing unit, after data analysis is handled, delivers to the voice unit 8 that links to each other with it.
In Fig. 4, the resistance that calibrating terminal 14 senses is delivered to the base stage of audion T1BC548 with the form of voltage signal, base stage links to each other with slide rheostat VR1 simultaneously, to be used for the resistance of regulating circuit to the human body relaxed state, the emitter stage of audion T1BC548 links to each other with slide rheostat VR2, the slide plate of slide rheostat VR2 links to each other with the analog digital conversion pin of single-chip microcomputer, in order to carry out the processing of data.
