Abstract

The utility model provides a photoelectric sphygmomanometer used for measuring blood pressure of the human body. A power switch of the sphygmomanometer is opened, a pressurizing inflation ball is used for inflating and pressurizing a cuff bag tied on one arm of the human body through a pressurizing air pipe, air pressure in the cuff bag is used for inflating and pressurizing a metal bellows through a communication air pipe, the metal bellows is arranged in a lower cover and fixed on a metal support, and when affected by air pressure, the bellows telescopes and shifts, so that an ejector rod pushes a lever and a pull rod to drive a large gear and a small gear to rotate; rotation of the small gear will drive a coaxial laser tube to rotate so that two laser column points emitted by the laser tube and illuminated on a blood pressure dividing ruler can move vertically on the blood pressure dividing ruler along with the condition of blood pressure, different angles of the two laser column points are suitable for the different pressure sections, and therefore the blood pressure of the human body can be measured. According to the photoelectric sphygmomanometer, by opening a heart rate measuring switch, a heart rate sensor in the cuff bag can measure the heart rate of the human body and display the heart rate on a digital heart rate displayer.

Description

Photoelectricity sphygomanometer

Technical field:

This utility model is in medical device technology product scope: a kind of instrument that is used for measuring human blood-pressure situation.It is to promote luminous laser tube transmission with air pressure, and the laser pin deck that use moves up and down is carried out Measure blood pressure and is equipped with the medical product of a kind of electromechanical integration of electronics heart rate measurement and demonstration.

Background technology:

Measuring in the product of human blood-pressure situation: one is normally used mercurial sphygmomanometer for many years.Its method is: be banded in sleeve bag on human body arm by giving, give the inflation of sleeve bag by pressurization inflatable ball by pressure-vent pipe, the air pressure in sleeve bag promotes hydrargyrum in mercury boxes along being with graduated hollow glass tube to rise or decline by connectivity trachea again.The hydrargyrum that the situation that on human body arm, arteriotony is beated like this will promote in glass tubing moves up and down, and the situation that hydrargyrum moves also shows on the glass tubing that is provided with rule.Thereby will demonstrating the high pressure of human blood-pressure and the blood pressure situation of low pressure, suitable increase air pressure or aerofluxus blood pressure lowering measure the blood pressure of human body.This method is simple, stable, effective, but hydrargyrum also bring pollution with regard to a large amount of uses or the discarded meeting of hydrargyrum to ecological environment, is unfavorable for environmental conservation.

Also having one is gauge outfit formula sphygomanometer: it is to promote metal bellows with air pressure, promotes gear by corrugated tube, then drives pointer to rotate Measure blood pressure by gear by gear graduation.Because pointer is that blood pressure data is indicated in rotation, in the time measuring and in traditional mercurial sphygmomanometer, the mode that move up and down of mercury column in glass tubing do not meet, and visual effect difference, is inconvenient to observe.The degree of accuracy of this sphygomanometer is low in addition, and error ratio is larger, and general conduct portably uses the reference use with blood pressure situation.

Another is electric sphygmomanometer: its method is to the sleeve bag inflation being banded on human body arm by electric gas-filled method, air pressure situation in sleeve bag is delivered to the signal of telecommunication in microprocessor and is processed by the pressure transducer being arranged in sleeve bag, then the blood pressure data of processing by electronic display screen displays out.This electric gas-filled also bleed is progressively heart rate thereby measure the number of times that high pressure, low pressure and one point of kind of heart of human blood-pressure beat.The advantage of this method is that several sub-display of blood pressure are directly perceived, but numeral fluctuation is larger, and accuracy rate is lower, is generally used as the reference use of human blood-pressure situation.

Summary of the invention:

In mercurial sphygmomanometer, be all also to change and carry out Measure blood pressure with regard to the height of mercury column with hydrargyrum, hydrargyrum namely use or the discarded meeting of hydrargyrum bring pollution to ecological environment.There is the use of polluting hydrargyrum in order to replace, the technical scheme the utility model proposes is: carry out displacement with the telescopic corrugated tube of elasticity that has that air pressure promotes to make with metal, the lever and the gear that promote to have amplification by the displacement of corrugated tube again rotate, make the gear shaft rotating drive coaxial laser tube also to rotate, make laser post that laser tube launches or laser spots vertical with the plane of blood pressure rule on along with the fluctuation of blood pressure moves up and down, moving up and down of laser pin deck is similar to moving up and down of mercury column, and be greater than the amount of movement of mercury column, thereby the blood pressure situation of measuring human body on blood pressure rule is come.Opening heart rate detection switch can make heart rate sensor detect the heart rate of human body and show to come on heart rate character display.

This utility model solves the technical scheme that its technical problem adopts:

In an openable rectangular box, on box, cover the blood pressure rule that is provided with two different mercury column of mark and pressure, after box lower cover, be provided with a metal rack, on support, fix the metal bellows of opening other end sealing with a fine-tuning nut, the sleeve bag that of wavy metal tube opening is banded on human body arm by UNICOM's trachea with while measuring human blood-pressure is connected; One of corrugated tube sealing is connected with a lever that can rotate with axle by a push rod, and upper and lower the covering of lever arm is provided with returning pull-spring, makes energy return after corrugated tube and lever displacement.The head of lever is above connected with the off normal point on a gear wheel by a pull bar, lever can make gear wheel rotate by pull bar and drive the pinion rotation that is engaged in gear wheel, and the rotation of pinion can be sent the laser pin deck of two different angles laser tube on can driving and being arranged on coaxially rotates.The rotation of laser tube can make to be irradiated to two laser pin deck on blood pressure rule along with the situation of human blood-pressure moves up and down, thereby the blood pressure situation of measuring human body is come.

Because the displacement of corrugated tube is amplified by lever, gear, laser post or the mobile range of laser spots on blood pressure rule that laser tube is penetrated are very large, in order not make blood pressure rule lengthen, can launch so be provided with two on laser tube the laser pin deck that different angles adapt to different pressures section, also on blood pressure rule, be also provided with the blood pressure rule of two different pressures sections, want with the displacement that adapts to two laser pin deck simultaneously.

In order to proofread the accurate location of laser pin deck on blood pressure rule, in the time that pressure is zero, laser tube can be in low head status, at this moment laser pin deck can be irradiated less than on rule, therefore below box, is provided with a reflecting mirror and laser pin deck is reflexed to rule gets on for the check and correction of pressure zero.The check and correction of pressure spot is to complete by the fixing metal rack of corrugated tube and the fine-tuning nut of fixing corrugated tube.

For laser tube is not shaken, on laser tube, be provided with balancing weight, the size of balancing weight and the fixed position on laser tube can be adjusted.

In sleeve bag, be provided with heart rate detection sensor in addition, in sphygomanometer box, be provided with heart rate detection switch and heart rate character display.In the time measuring human blood-pressure, opening heart rate detection switch can out and on heart rate character display show heart rate detection.Laser tube in sphygomanometer is luminous, heart rate detection, and parts such as heart rate numeral demonstrations grade are powered by and off switch by set of cells.
