Description

Technical Field

[0001] This invention relates to the field of blood pressure monitors, and more specifically, to a home-use split-type blood pressure monitor. Background Technology

[0002] Blood pressure monitors are mainly divided into auscultatory blood pressure monitors and oscillometric blood pressure monitors. The auscultatory method is further divided into manual and automatic auscultatory methods. Mercury sphygmomanometers (pressure gauges) and spring-loaded sphygmomanometers (pressure gauges) are early examples of manual auscultatory blood pressure monitors. Modern manual auscultatory blood pressure monitors include digital display sphygmomanometers, light bar sphygmomanometers, light display sphygmomanometers, and LCD sphygmomanometers. Automating the auscultatory method is technically challenging. For home use, electronic blood pressure monitors are primarily used for ease of operation.

[0045] A method for using a home-use split-type blood pressure monitor, characterized by comprising the following steps: S1: Connect the charging interface 11 to a power source using a charger, turn on the button 12 to charge the charging board 10, and charge the battery 46 through the output spring pin 9 and the input copper post 24. S2: Turn on the switch button 13, the screen 5 works, the screen 5 displays the power of the battery 46, and when the battery 46 is fully charged, remove the split-type boom assembly. S3: Place the split arm sleeve assembly on the arm at a suitable position, operate the function button 14 to activate one of the air pumps 20 and one of the solenoid valves 19, enabling the retractable part 36 to quickly inflate and stabilize the arm circumference size, and one of the sensors 29 to sense the preset pressure.

Another sensor 29 converts the sound of the brachial artery pulse into an electrical signal and sends it to the measuring circuit board 22, displaying the data on the screen 5.

[0046] After the split arm sleeve assembly is fitted onto the arm, the function button 14 is operated to quickly inflate the retractable part 36 to stabilize the arm circumference size, so that the mesh 35 fits tightly against the arm, and the split arm sleeve assembly has a certain contractile force to fix it on the arm. The pressure value is generally fixed in a range, for example, 30~40 mmHg. Within this range, a value is taken as the set value. When the pressure value reaches the set value, the measuring circuit board 22 shuts down one of the air pumps 20 and one of the solenoid valves 19. The function button 14 is then operated to activate the other air pump 20 and the other solenoid valve 19, so that the small airbag 37 can be activated to achieve blood pressure measurement.

The retraction component 36 is provided with a measuring half-window 42. By using the front guide grooves 39 and rear guide grooves 32, the extension and limiting of the rear extension cylinder 30 and the front extension cylinder 38 are achieved. After the rear extension cylinder 30 and the front extension cylinder 38 are withdrawn, the arm cylinder reaches the professional measurement dimensions. After the rear extension cylinder 30 and the front extension cylinder 38 are retracted, they can be easily stored. By setting the front measurement window 40 and the rear measurement window 33, the movement of the rear extension cylinder 30 and the front extension cylinder 38 can be facilitated, so that they will not touch the sensor 29 or the connecting air pipe 18, and the volume expansion of the retractable part 36 and the small air bag 37 during pressurization can be facilitated.

[0048] The two air tubes 18 pass through the measuring window 44, the rear measuring window 33, the front measuring window 40 and the notched annular EVA cotton 34 in sequence, and the notched annular EVA cotton 34 clamps the air tubes 18.

[0049] A method for using a home-use split-type blood pressure monitor, characterized by comprising the following steps: S1: Connect the charging interface 11 to a power source using a charger, turn on the button 12 to charge the charging board 10, and charge the battery 46 through the output spring pin 9 and the input copper post 24. S2: Turn on the switch button 13, the screen 5 works, the screen 5 displays the power of the battery 46, and when the battery 46 is fully charged, remove the split-type boom assembly. S3: Extend the rear stretching cylinder 30 and the front stretching cylinder 38 outward to move the rear stretching cylinder 30 and the front stretching cylinder 38 along the guide cylinder 25, so that the guide cylinder 25 contacts the end positions of the rear guide groove 32 and the front guide groove 39. S4: Place the split arm sleeve assembly on the arm at a suitable position, operate the function button 14 to activate one of the air pumps 20 and one of the solenoid valves 19, enabling the retractable part 36 to quickly inflate and stabilize the arm circumference size, and one of the sensors 29 to sense the preset pressure. The measuring circuit board 22 then shuts down one of the air pumps 20 and one of the solenoid valves 19 to keep the retractable part 36 in place. Operate the function button 14 to activate another air pump 20 and another solenoid valve 19, enabling the small airbag 37 to function. Another sensor 29 converts the sound of the brachial artery pulse into an electrical signal and sends it to the measuring circuit board 22, displaying the data on the screen 5.

[0050] After the split arm sleeve assembly is fitted onto the arm, the function button 14 is operated to quickly inflate the retractable part 36 to stabilize the arm circumference size, so that the mesh 35 fits tightly against the arm, and the split arm sleeve assembly has a certain contractile force to fix it on the arm. The pressure value is generally fixed in a range, for example, 30~40 mmHg. Within this range, a value is taken as the set value. When the pressure value reaches the set value, the measuring circuit board 22 shuts down one of the air pumps 20 and one of the solenoid valves 19. The function button 14 is then operated to activate the other air pump 20 and the other solenoid valve 19, so that the small airbag 37 can be activated to achieve blood pressure measurement.

[0051] This invention employs a dual-airbag arm cuff design. By operating the function button 14, the retractable component 36 is rapidly inflated, allowing the mesh 35 to fit tightly against the arm. This provides the split arm cuff assembly with a certain amount of contractile force to fix it to the arm, enabling the retractable component 36 to quickly inflate and stabilize the arm circumference. When the small airbag 37 is inflated, it allows for accurate blood pressure measurement. This invention adapts to situations where different users have different arm circumferences and solves the problem of inconsistent arm cuff sizes.

[0052] The double-sided pull-out structure of the boom of this invention enables the boom to reach professional measurement dimensions, improving measurement accuracy, while reducing the product's footprint and solving the storage problem.

[0053] This invention uses a separate integrated arm sleeve, which reduces the number of components such as the trachea, and the simpler slip-on design makes it more convenient to use, solving the problem that it is inconvenient for the elderly to wear when using it alone.

[0054] The above-disclosed embodiments are merely specific examples of the present invention. However, the present invention is not limited thereto, and any variations that can be conceived by those skilled in the art should fall within the protection scope of the present invention.
