Description

Three-way cuff sphygmomanometer

Technical Field

The invention relates to the technical field of medical instruments, in particular to a three-way cuff sphygmomanometer.

Background

Systemic arterial blood pressure is called blood pressure for short; the blood pressure is the pressure acting on the wall of a blood vessel when blood flows in the blood vessel, and is the power for pushing the blood to flow in the blood vessel; ventricular contraction, in which blood flows from the ventricle into the artery, at which time the pressure of the blood against the artery is highest, called systolic pressure; the ventricles relax, the arterial vessels retract elastically, and blood continues to flow forward slowly, but the blood pressure drops, at which point the pressure is called the diastolic pressure.

A sphygmomanometer is an instrument for measuring blood pressure, and is also called as a sphygmomanometer; the main principle of the sphygmomanometer is a process of measuring the blood flow pressure in the period by pressurizing air to press a local artery and applying pressure to stop the pulsation of the local artery; the measurement principle of the blood pressure set can be divided into an auscultation method and an oscillography method; the auscultatory method is also called Korotkoff sound method, and is also divided into artificial Korotkoff sound method and electronic Korotkoff sound method; the artificial Korotkoff sound method is a method which is commonly seen by doctors and nurses and is used for measuring blood pressure by using a pressure gauge and a stethoscope; the electronic Korotkoff sound rule is a Korotkoff sound measuring method which replaces doctors and nurses with electronic technology; the principle is that a cuff is wound on the upper arm, and the pressure of the cuff acts on the brachial artery; adjusting the cuff air to change the pressure, and listening to the pulsating sound by using a stethoscope so as to obtain systolic pressure and diastolic pressure; the oscillography, also called the oscillation method, is a relatively advanced electronic measuring method developed in the 90 s of the 20 th century, and the principle thereof is that the inflation quantity of a cuff wound on an upper arm is automatically adjusted, the pressure is changed, blood flow has certain oscillation waves through blood vessels, the blood flow is received by a pressure sensor and is gradually deflated, the pressure and the fluctuation detected by the pressure sensor are changed along with the change of the oscillation waves, the moment with the maximum fluctuation is selected as a reference point, on the basis of the point, the fluctuation point with a certain value is searched forwards as the systolic pressure, a certain value is searched backwards to obtain the fluctuation point as the diastolic pressure, and the value is set differently by different manufacturers.

At present, different groups of people, including adults or children, are often encountered during blood pressure measurement, and the pressurizing value is also influenced during measurement due to the difference of the thicknesses of arms, so that cuffs of different sphygmomanometers need to be replaced during measurement of adults and children, cuffs of children are short and narrow, cuffs of adults are long and wide, replacement is very troublesome, and particularly, delay is avoided when sudden or rescue incidents occur.

Example 3

Referring to fig. 1, fig. 1 is a schematic structural diagram of a three-way cuff sphygmomanometer according to an embodiment of the present invention. The using method of the three-way cuff sphygmomanometer comprises the following steps:

1. the subject takes the sitting position or the supine position, rolls up the sleeves to the armpits or takes off the sleeves on one side, then puts the arms at the same level with the heart and abducts for 45 degrees.

2. The air in the cuff of the electronic sphygmomanometer is exhausted, then the cuff is flatly attached to the upper arm of the testee, and the cuff cannot be too loose or too tight so as not to influence the accuracy of the measured value.

3. When the cuff is wrapped, the middle part of the cuff is placed at the brachial artery of the elbow socket of the tested person, namely the inner side of the arm and the 2 cm position above the elbow socket, and the pulse can be sensed by pressing the brachial artery with the thumb so as to avoid reducing the sensitivity of a baroreceptor.

3. Starting the electronic sphygmomanometer to measure; when the cuff is inflated, attention should be paid to observe whether the cuff bonding port is cracked; if the bonding opening is cracked, the cuff is tightly wound again for the testee to measure; and after the electronic sphygmomanometer displays the numerical value, recording the blood pressure value displayed by the sphygmomanometer.

4. After the air in the cuff is exhausted, the cuff is taken down from the upper arm of the testee, the testee is allowed to rest for a moment, and then the blood pressure value is measured again for 1-2 times according to the method; finally, the average value of the blood pressure measured for several times is taken, and the value is the real blood pressure value of the tested person.

If the testee needs to determine whether the testee has hypertension, the blood pressure value of the same arm is measured by the same sphygmomanometer at different times (at least 3 different times) on the same day, so that the testee can determine whether the testee has hypertension.

The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, various modifications and additions can be made without departing from the principle of the present invention, and these should also be considered as the protection scope of the present invention.
