Abstract
The utility model relates to a sphygmomanometer which can utilize an electromagnetic valve and an electronic control circuit to automatically measure the blood pressure on the basis of a mechanical sphygmomanometer (a mercury type, a manometer type, etc.). The utility model is characterized in that the electromagnetic valve automatically controls the slow deflation and the actions of the deflation and the deflation stop of the electromagnetic valve are controlled by a control circuit; when the control circuit judges the appearance of the high pressure (systolic pressure) signal and the low pressure (comfortable pressure) signal, the blood pressure finger type device (mercury column, pressure meter pointer, etc.) automatically stops moving. An operator reads out the corresponding pressure value with sufficient time and the electromagnetic valve emits the sound whose frequency is consistent with that of the heart rate and the utility model has the advantages of convenient use, high precision, low cost, etc.
Description
This utility model relates to sphygomanometer, especially a kind of control device that is applied to the mechanical type sphygomanometer, and the sphygomanometer of the automatic measuring blood pressure of being made up of this device of various energy.
At present typical blood pressure is in respect of following three classes: 1. mechanical type sphygomanometer.Adopt mechanical pressure indicator indication pressure values such as hydrargyrum (hydrargyrum) post, gauge hand, must unite use with stethoscope, after utilizing the interior airbag aeration of arm band to add certain pressure for the arm brachial artery, the Artificial Control venting, in deflation course, determine high pressure (systolic pressure) and low pressure (diastolic pressure) by the Ke Luotefu sound (Korotkoff ' s Sound) that artificial monitoring brachial artery produces.The problem that exists is: generally need training correctly to use, this enters average family to sphygomanometer, and particularly the gerontal patient brings inconvenience; The determining to change at pressure indicator in (mercury column or gauge hand are in motion) process of high and low pressure carries out reading, and this " dynamically " test result is difficult for accurate reading, thereby influences measuring accuracy; Arm band air bag deflation is by Artificial Control, wayward venting speed, and venting speed directly influences measuring accuracy.2. the sphygomanometer that has electronic stethoscope.This class sphygomanometer typical technology has patent CN91215913 and CN94226342 etc., and basic fundamental only changes stethoscope into electronic stethoscope, and using method and mechanical type sphygomanometer are basic identical.Electronic stethoscope is just emitted the sound of brachial dance by " buzzer " or " speaker ", still need to monitor, Artificial Control is also wanted in venting, also is to read high pressure and low pressure in the pressure change procedure, does not therefore fundamentally overcome the problem that the mechanical type sphygomanometer exists.In addition, electronic stethoscope is heard sound through after amplifying, and hears that with stethoscope sound intensity etc. has any different, and by experiment, finds that when electronic stethoscope sends first, at this moment stethoscope but be can't hear sound, brings error therefore for the judgement pressure value.3. numeral shows electric sphygmomanometer.Adopts pressure sensor converts pressure to the signal of telecommunication, handles through electronic circuit, single-chip microcomputer etc. again, and numeral shows that (liquid crystal or charactron) demonstrates high pressure, low pressure and heart rate automatically.The problem that exists is: because the conversion accuracy of pressure transducer directly influences the measuring accuracy of blood pressure, but the high pressure transducer cost height of precision is added circuit structure complexity, applying electronic display etc., so sphygomanometer cost height; Being seen this class sphygomanometer retest result differs bigger on the market in addition, and the impression of giving the medical personnel is that test is inaccurate, and it is accurate to be not so good as the mechanical type sphygomanometer.
This utility model purpose has provided a kind of control device that is used for the mechanical type sphygomanometer, and installs the sphygomanometer of forming with this.
Control device described in the utility model is made up of following three parts: 1. photoelectricity/acoustical-electrical transducer.It will be subjected to the fight conversion of signals of arteriopalmus of the upper arm behind the certain pressure is the signal of telecommunication.2. control circuit.Brachial artery signal after it will be changed is handled, and can judge the signal when high pressure and low pressure occurring automatically, send electromagnetic valve, with the action of control electromagnetic valve; It is made up of amplifying circuit, discriminator circuit, delay circuit, logic circuit and drive circuit, the signal output of photoelectricity/acoustical-electrical transducer is connected to input amplifier, amplifying circuit output divides two-way to be defeated by discriminator circuit, logic circuit connects discriminator circuit, delay circuit and drive circuit, and drive circuit connects the control coil of electromagnetic valve.3. electromagnetic valve.With three links it is inserted in the gas circuit of mechanical type sphygomanometer, under the control circuit effect, " venting " and " parking gas " of air bag in the control arm band automatically; It is made up of electric magnet, control coil, spring leaf, trachea and support, and constitutes the valve of electromagnetic valve by spring leaf and gas tube orifice, and the gas tube orifice diameter is got 0.5～1mm.
Sphygomanometer described in the utility model, form by above-mentioned control device, aerating device, arm band, mechanical compression indicator (mercury column, Pressure gauge etc.), the arm band is communicated with the mechanical compression indicator, and arm band, aerating device and electromagnetic valve are communicated with three links.
After this control device and mechanical type sphygomanometer link, the work process of sphygomanometer is as follows: can adopt artificial or the electric air pump inflation to arm band airbag aeration, venting solenoid control automatic deflation, pressure reduces gradually in deflation course, when control circuit is judged high pressure (systolic pressure), sending signal at stop electromagnetic valve (can hear the sound of closed electromagnetic valve this moment) makes air bag stop the several seconds venting, this moment blood pressure indicator (mercury column, air gauge pointer etc.) also stop motion, the operator can accurately read pressure (high pressure) value of this moment in time several seconds of this stop motion; The later brachial dance signal that sends with controller, electromagnetic valve alternately carries out " venting " and " parking gas " action with the rhythm and pace of moving things of beating, can hear the frequency sound consistent that electromagnetic valve sends with heart rate, intracapsular pressure also continues to reduce gradually, judge when low pressure (diastolic pressure) signal occurring up to controller, electromagnetic valve is closed (also stopping sounding), the indicated numerical value of blood pressure indicator (mercury column, gauge hand etc.) of stop motion this moment, be low voltage value, thereby finish the one-shot measurement process.
The sphygomanometer that this utility model is related, basically overcome the problem that above-mentioned three class sphygomanometers exist, combine simultaneously their advantage again, its characteristics are as follows: 1. the function that has automatic measuring blood pressure, as long as generally consulting the operation instruction postscript promptly can correctly use, do not need special training, so easy to use; 2. compare with mechanical type sphygomanometer and the sphygomanometer that has electronic stethoscope, owing to have enough time accurate readings (because of stop motion such as mercury column or gauge hand at this moment) when reading pressure value, needn't manually monitor and judge pressure value, and control air bag deflation etc. automatically, so the measuring accuracy height; Show that with numeral relatively, owing to there is not adopts pressure sensor, there is not the transformed error that is converted to the signal of telecommunication by pressure in electric sphygmomanometer, so measuring accuracy is also wanted height; 3. show electric sphygmomanometer relatively with numeral, cost is low below 50%, so this class sphygomanometer is easily accepted by average family.
