Title: Device for correcting position of heart when measuring blood pressure

Description:
TECHNOSPHERE 
     The invention relates to the technical field of blood pressure measurement, and more specifically, it relates to a device for correcting the position of the heart when measuring blood pressure. 
     BACKGROUND TECHNOLOGY 
     Blood pressure refers to the lateral pressure that acts on the blood vessel wall per unit area when blood flows in a blood vessel. It is called arterial blood pressure, capillary pressure and venous blood pressure in different blood vessels. The blood pressure is usually referred to as the arterial blood pressure of the systemic circulation. 
     Hypertension is characterized by an increase in systemic arterial blood pressure (systolic and/or diastolic blood pressure) (systolic blood pressure ≥140 mm Hg, diastolic blood pressure ≥90 mm Hg), which may be accompanied by the functions of organs such as heart, brain, kidney Or clinical syndrome of organic damage. Hypertension is the most common chronic disease and the most important risk factor for cardiovascular and cerebrovascular diseases. Normal people&#39;s blood pressure fluctuates within a certain range with changes in the internal and external environment. In the overall population, blood pressure levels gradually increased with age, and systolic blood pressure was more obvious, but diastolic blood pressure showed a downward trend after 50 years of age, and pulse pressure also increased. 
     Blood pressure measurement is one of the must-do items for patients with hypertension. However, there are the following problems in the process of measuring blood pressure in patients with hypertension: When patients measure blood pressure, patients will sit in chairs prepared by the hospital The arm is placed on the diagnosis and treatment table. The height of the diagnosis table and chair is fixed, and the height will not be adjusted due to the difference in patient height. Patients of different heights use the same height table and chair; in this way, the patient is measuring blood pressure At this time, it is inevitable that the brachial artery of the patient&#39;s upper arm and the patient&#39;s heart are on the same level. If the arm for measuring blood pressure is too high or too low, the blood pressure measurement value will be inaccurate, which will make the patient&#39;s blood pressure measurement result inaccurate, which is not conducive to the patient&#39;s subsequent treatment, especially to the doctor&#39;s control of the patient&#39;s medication. Because the blood pressure measured by the individual patient is inaccurate, it cannot provide the patient with a reliable basis for medication, which greatly affects the control of blood pressure in patients with hypertension, resulting in cardiovascular and cerebrovascular accidents, leading to patient disability and even death. Therefore, a device for correcting the position of the heart when measuring blood pressure is proposed to solve the above problem.

     From the comparative analysis of the test results in the above table, it can be seen that Example 3 is the best example. By adopting the above technical solution, the process steps for preparing protective coatings are simple and easy to implement. The prepared protective coatings have moderate viscosity, are not easy to delaminate, are easy to spray, and have no bubbles Produced and fully combined with various components, the overall performance is good, so that the protective coating can form a better coating film after spraying, it is not easy to produce cracks, and the film formation effect is better. The prepared protective layer has good corrosion resistance, wear resistance, Anti-skid, anti-aging performance, good adhesion, not easy to fall off, can effectively increase the anti-corrosion, wear-resistant, anti-skid, anti-aging performance of the base  1 , so that the device has a longer service life, especially important is to prevent medical personnel The patient slipped when using the device with the patient. 
     Working principle: In the device for checking the position of the heart when measuring blood pressure, the first support unit  2  is used as a seat for medical staff to diagnose patients; the second support unit  3  is used as an examination table when measuring blood pressure; and the third support unit  4  It is used as a seat for patients to measure blood pressure; this device sets the first support unit  2 , the second support unit  3  and the third support unit  4  all on the upper part of the base  1 , adopts an integrated design, so that the whole device structure is relatively stable, It can effectively prevent the first support unit  2 , the second support unit  3  and the third support unit  4  from falling down, and can avoid the accidents of medical staff and patients falling when measuring blood pressure, especially for those over 75 years old For hypertensive patients, accidental falls directly threaten their life safety. In addition, the third support unit  4  is driven by a motor  15  to adjust the height of the third support plate  13 , so when the patient sits on the upper part of the third support plate  13 , The position of the patient can be adjusted by controlling the motor  15  and the patient&#39;s right arm is placed on the upper part of the second support plate  9  at the same time. By adjusting the position of the patient, the elbow of the patient&#39;s right arm and the heart of the patient can be On the same level, the patient&#39;s heart position when blood pressure is measured is now corrected, so that the patient&#39;s blood pressure measurement result is more accurate and the error is smaller, which is conducive to the patient&#39;s subsequent treatment, especially for the doctor to control the patient&#39;s medication.

     The fourth step, the medical staff sits on the upper part of the first support plate  7  and al lows the patient to take off the clothes of the right arm, preferably to expose the skin, and then the patient places the front end of the right arm on the upper part of the second support plate  9 , The medical staff controls the operation of the motor  15  by operating the control switch  10 , and uses the motor  15  to drive the screw  17  to run, so that the cylindrical support block  19  moves up and down along the screw  17  under the restriction of the two guide rods  18 , which can be easily adjusted The height of the third support plate  13  makes the elbow of the right arm of the patient and the heart of the patient on the same level. At this time, the position of the heart of the patient when measuring the blood pressure is completed. Blood pressure is measured.
