Abstract
Description
Technical Field
[0001] This utility model relates to the field of blood pressure monitors, and in particular to an integrated upper arm blood pressure monitor. Background Technology
[0002] Currently, most arm-type electronic blood pressure monitors on the market consist mainly of the monitor body and a cuff with a tubing. The vast majority of electronic blood pressure monitors on the market use the oscillometric method for blood pressure measurement. Oscillometric electronic blood pressure monitors (hereinafter referred to as blood pressure monitors) work by measuring the pressure changes in the cuff wrapped around the arm from high to low. As the pressure changes, the artery in the arm transitions from being blocked to being open, causing a series of small pressure pulses to be superimposed on the cuff pressure. The pressure sensor senses these signals, calculates the systolic and diastolic blood pressure, and heart rate, and then sends the test results out for display and stores in the memory unit. Existing electronic blood pressure monitors consist of two parts: a cuff and a main unit. Because the cuff and main unit are separate, the cuff's tubing interface must be inserted into the main unit's interface during use. Repeated insertion and removal of this interface can lead to air leakage after a period of use, affecting measurement accuracy. Furthermore, the separate cuff and main unit design makes them inconvenient to store and carry. Additionally, they lack the design to collect angular acceleration data related to patient position, making it impossible to accurately sense changes in patient position in real time. This means they fail to consider the impact of positional changes on blood pressure values and cannot effectively combine patient positional change data with real-time blood pressure values, easily leading to missed diagnoses and unexpected situations, thus compromising reliability and accuracy.
[0003] Therefore, a new technology needs to be developed to solve the above problems. Utility Model Content

[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] An integrated upper arm blood pressure monitor includes an arm cuff for wrapping around the upper arm of a person whose blood pressure is being measured and a housing mounted on the arm cuff.

[0010] The MCU processor is connected to a power supply, buttons, a voice player, and an LCD display. The power supply is located inside the housing, while the buttons and the LCD display are located on the surface of the housing.

[0037] An integrated upper arm blood pressure monitor includes an arm cuff 10 for wrapping around the upper arm of a person whose blood pressure is to be measured and a housing 20 mounted on the arm cuff 10. The housing 20 contains a PCB board 30, an MCU processor 40, an air pump 50, a pressure sensor 60, a vent valve 70, and a gyroscope 80. The MCU processor 40 is connected to the PCB board 30. An air passage is provided within the housing 20. The air pump 50 and the vent valve 70 are respectively connected to the air inlet of the air passage, and the air outlet of the air passage is connected to an air bladder inside the arm cuff 10. The pressure sensor 60 is used to detect pressure changes in the air passage.
[0038] The air pump 50 is connected to the arm cuff 10 and the MCU processor 40. The MCU processor 40 controls the air pump 50 to inflate the air bladder in the arm cuff 10. The deflation valve 70 is connected to the arm cuff 10 and the MCU processor 40. The MCU processor 40 controls the deflation valve 70 to deflate the air bladder in the arm cuff 10. The pressure sensor 60 is connected to the arm cuff 10 and the MCU processor 40. The gyroscope 80 is connected to the arm cuff 10 and the MCU processor 40. The gyroscope 80 is used to provide an error message when the patient moves their limbs during blood pressure measurement, indicating that the patient needs to readjust and the measurement should be performed. Here, the gyroscope 80 can collect angular acceleration data related to the patient's position in real time to accurately sense changes in the patient's position. This data, combined with the processor, enables real-time blood pressure monitoring, taking into account the impact of positional changes on blood pressure values. By effectively combining the patient's positional change data with the real-time blood pressure values through data analysis and processing by the MCU processor 40, the occurrence of missed diagnoses and unexpected situations is reduced, making the measurement more reliable and accurate.
[0039] The MCU processor 40 is connected to a power supply 90, buttons 101, a voice player 102, and an LCD display 103. The power supply 90 is located inside the housing 20. The buttons 101 and the LCD display 103 are both located on the surface of the housing 20. The voice player 102 is located on the housing 20 and protrudes from its surface. Preferably, in this embodiment, the MCU processor 40 is connected to the power supply 90 via a power circuit, the buttons 101 via a button circuit, the LCD display 103 via an LCD circuit, and the voice player 102 via a voice circuit. Thus, the data measured by the blood pressure monitor can be displayed on the LCD display 103 or broadcast via the voice player 102. Furthermore, when the gyroscope 80 issues an error message due to limb movement during blood pressure measurement, it provides a voice prompt via the voice player 102 and a screen display prompt via the LCD display 103, allowing the user to understand the situation promptly.
[0040] The housing 20 includes a first housing 21 and a second housing 22. The first housing 21 is connected to the arm strap 10, and the second housing 22 is assembled on the front side of the first housing 21. The first housing 21 and the second housing 22 form an installation cavity. The PCB board 30, MCU processor 40, air pump 50, pressure sensor 60, vent valve 70, gyroscope 80, power supply 90, and voice player 102 are all disposed in the installation cavity. The button 101 and LCD display screen 103 are disposed on the front side wall of the second housing 22, and the button 101 is located on the upper side of the LCD display screen 103.
[0041] The front side of the first housing 21 is provided with a plurality of first connecting protrusions 23, and the rear inner side wall of the second housing 22 is provided with a plurality of second connecting protrusions 24. The first connecting protrusions 23 are connected together with the corresponding second connecting protrusions 24.
[0042] The rear inner sidewall of the second housing 22 has a protruding mounting shell 25 for mounting the battery 104. The mounting shell 25 has a receiving cavity 26 with a rear opening. The power supply 90 includes the battery 104, which is mounted in the receiving cavity 26. In this embodiment, the battery 104 is a lithium battery. The PCB board 30 is located above the mounting shell 25, and the battery 104 is connected to the PCB board 30. A charging interface 105 is provided at the upper end of the second housing 22, and the charging interface 105 is electrically connected to the PCB board 30. The charging interface 105 is a Type-C interface. Thus, the battery 104 can be charged or powered through the Type-C interface.
[0043] Furthermore, in this embodiment, the first housing 21 has a forward-recessed arc-shaped connecting surface on the side facing the arm cuff 10. This arc-shaped connecting surface ensures a tighter connection between the first housing 21 and the arm cuff 10, and prevents the housing 20 from affecting the bending and wrapping of the arm cuff 10 when it bends. Preferably, the housing 20 can be configured to extend in an arc shape along the bending direction of the arm cuff 10, making the blood pressure monitor more aesthetically pleasing.
[0044] In summary, this design primarily involves assembling a housing onto the arm cuff, with a PCB board, MCU processor, air pump, pressure sensor, vent valve, and gyroscope housed within the housing. The MCU processor is connected to a power supply, buttons, a voice player, and an LCD display. The power supply is located inside the housing, while the buttons and LCD display are on the surface. The voice player is mounted on the housing and protrudes from its surface. This integrated design eliminates the need for repeated insertion and removal of the air tube, preventing air leakage and ensuring reliable and accurate measurements. It is also easy to store and carry. Furthermore, the gyroscope is used to alert the user to any limb movement during blood pressure measurement, indicating when further blood pressure readings are needed. The patient is readjusted and the blood pressure is measured again, which makes the measurement data more accurate and stable. Furthermore, the gyroscope is configured to collect angular acceleration data related to the patient's position in real time, accurately sensing changes in the patient's position. This data, combined with the processor, enables real-time blood pressure monitoring, taking into account the impact of positional changes on blood pressure values. The patient's positional change data is effectively combined with the real-time blood pressure value through data analysis and processing by the MCU processor, reducing missed diagnoses and unexpected situations, making the measurement more reliable and accurate. Additionally, when the gyroscope issues an error message if the patient moves their limbs during blood pressure measurement, it can provide voice prompts via a voice player and display a screen message on the LCD screen, allowing the user to understand the situation promptly.

Therefore, any minor modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model shall still fall within the scope of the technical solution of the present utility model.
