Description

Technical Field

[0001] This utility model relates to the field of arm-type blood pressure monitor technology, specifically an arm-type blood pressure monitor with an adjustable tilt angle. Background Technology

[0002] In the field of blood pressure measurement, arm-type electronic blood pressure monitors are widely used due to their ease of operation and rapid measurement, but traditional devices have the following core problems.

[0003] Traditional arm-type blood pressure monitors rely on users to manually adjust the position of their arms, making it difficult to ensure that the center of the cuff bladder is precisely aligned with the brachial artery. Clinical data shows that when the angle between the arm and the axis of the measuring cylinder exceeds 10°, the measurement error of systolic blood pressure can reach ±5 mmHg, and the error of diastolic blood pressure can reach ±3 mmHg. Especially for the elderly, obese people, or those with relaxed arm muscles, due to differences in physiological bending angles, the accuracy rate of manual adjustment is only 60%-70%, leading to an increased risk of misdiagnosis. Utility Model Content

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Please see Figure 1-4 This utility model provides a new technical solution: an adjustable tilt arm blood pressure monitor, including an arm barrel electronic blood pressure monitor 1, an angle adjustment support assembly, the angle adjustment support assembly is disposed on the arm barrel electronic blood pressure monitor 1, the angle adjustment support assembly includes two rectangular mounting plates 8, both of which are fixedly connected to the rear surface of the arm barrel electronic blood pressure monitor 1.

[0031] Among them, the two rectangular mounting plates 8 are provided with forearm placement blocks 4 on their opposite sides, and transmission rods 9 are fixedly connected to both the left and right sides of the forearm placement blocks 4.

[0032] Among them, the opposing surfaces of the two transmission rods 9 rotate through the outer surface of the corresponding rectangular mounting plate 8, and the outer walls of the two transmission rods 9 are fixedly sleeved with the second gear 12.

[0033] Furthermore, the opposing surfaces of the rectangular mounting plate 8 are rotatably connected to drive shafts 13, and the opposing ends of the two drive shafts 13 are fixedly connected to the first gear 11.

[0034] Among them, the two first gears 11 are respectively meshed with the corresponding second gears 12.

[0035] Furthermore, protective covers 5 are fixedly installed on the opposite sides of the two rectangular mounting plates 8, and a servo motor 10 is installed inside the right protective cover 5.

[0036] The output end of the servo motor 10 is fixedly connected to the corresponding first gear 11.

[0037] Furthermore, the servo motor 10 is fixedly connected to the inner wall of the corresponding protective cover 5 by a mounting component.

[0038] Furthermore, two guide grooves 14 are formed on the rear surface of the forearm placement block 4, and auxiliary rods 2 are slidably connected to the inner walls of the two guide grooves 14. The palm placement block 3 is fixedly connected to the rear surface of the two auxiliary rods 2.

[0039] Furthermore, a mounting box 6 is fixedly connected to the lower surface of the forearm placement block 4, and an electric telescopic rod is fixedly installed inside the mounting box 6. The telescopic end of the electric telescopic rod slides through the rear surface of the mounting box 6.

[0040] The telescopic end of the electric telescopic pole is fixedly connected to a rectangular plate 7, which is fixedly connected to the palm placement block 3.

[0041] Furthermore, both the palm placement block 3 and the forearm placement block 4 have arc-shaped grooves on their upper surfaces, and arc-shaped pads are placed on the inner walls of both arc-shaped grooves.

[0042] Furthermore, when using this adjustable-angle arm-type blood pressure monitor, the operator first inserts their arm into the measuring cylinder inside the arm-type electronic blood pressure monitor 1, while simultaneously aligning their forearm with the arc-shaped groove of the forearm placement block 4 and their palm with the arc-shaped groove of the palm placement block 3. The elastic contact of the arc-shaped pad provides comfortable support and reduces shaking during measurement.

[0043] According to the physiological bending angle of the subject's arm, the servo motor 10 inside the right protective cover 5 is activated. The output end of the servo motor 10 drives the first gear 11 to rotate. Through gear meshing, the second gear 12 drives the transmission rod 9 to rotate, thereby adjusting the tilt angle of the forearm placement block 4 until the forearm and the axis of the measuring cylinder form a suitable angle, ensuring that the cuff airbag is aligned with the brachial artery.

[0044] If the hand position needs to be adjusted to accommodate different arm lengths, the electric telescopic rod in the mounting box 6 is activated. Its telescopic end pushes the rectangular plate 7 to move along the guide groove 14, which in turn drives the hand placement block 3 to slide in the guide groove 14 of the forearm placement block 4 through the auxiliary rod 2, so that the hand can be naturally stretched out and avoid muscle tension caused by the arm being suspended in the air.

[0045] During the angle adjustment process, the gear transmission structure ensures that the left and right forearm placement blocks 4 rotate synchronously to avoid angle deviation. The protective cover 5 protects the servo motor 10 to prevent dust or external forces from interfering with the transmission system. The sliding cooperation between the guide groove 14 and the auxiliary rod 2 ensures that the palm placement block 3 moves smoothly and avoids tilting or jamming.

[0046] Once the angle and position are adjusted, the self-locking function of the electric telescopic rod and the servo motor 10 remains in the current state, and the arm-type electronic blood pressure monitor 1 begins to inflate and measure. At this time, the stable support of the forearm placement block 4 and the palm placement block 3 reduces the influence of arm micro-movement on the blood pressure value.

[0047] Among them, when the size of the test subject's arm varies greatly, the forearm placement block 4 can be adjusted at multiple angles by the forward and reverse rotation of the servo motor 10. The stroke adjustment of the electric telescopic rod (such as 0~5cm telescopic amount) can adapt to different distances from the palm to the forearm. The replaceable design of the arc-shaped pad meets personalized comfort needs.

[0048] After the measurement is completed, the servo motor 10 reverses and resets the forearm placement block 4 to the initial horizontal state, and the electric telescopic rod retracts so that the palm placement block 3 is close to the forearm placement block 4, making it convenient for the next test subject to use quickly.

[0049] This device achieves adaptive matching for different arm shapes and angles through gear angle adjustment driven by a servo motor, fine-tuning of the position of the electric telescopic rod, and stable support of the guide sliding structure. It solves the measurement error problem caused by improper arm placement angle in traditional arm blood pressure monitors, improves the comfort and accuracy of the measurement process, and is suitable for home medical and clinical testing scenarios. It provides convenience for blood pressure measurement, especially for the elderly or people with limited mobility.

[0050] Structural Description:

[0051] Forearm placement block 4: Located between two rectangular mounting plates 8, the upper surface has an arc groove that fits the forearm of the person being tested. The left and right sides are connected to the second gear 12 through the transmission rod 9, which can rotate around the axis of the transmission rod to adjust the forearm placement angle (adjustment range 0-45°).

[0052] Transmission rod 9: Both ends pass through rectangular mounting plates 8 and are fixed to the forearm placement block 4. The outer wall is fitted with a second gear 12, which converts the rotational motion of the gear into the angle adjustment of the forearm placement block, ensuring that the left and right sides rotate synchronously (angle deviation ≤ 1°).

[0053] The second gear 12 is fixedly sleeved on the outer wall of the transmission rod 9 and meshes with the first gear 11. It receives the power of gear transmission and drives the transmission rod 9 to rotate, thereby realizing the tilt angle adjustment of the forearm placement block 4 (transmission ratio 1:1, ensuring uniform rotation).

[0054] Drive shaft 13: Rotatably connected to the outside of rectangular mounting plate 8, with the first gear 11 fixed at one end and a reserved mounting interface at the other end, transmitting the power of servo motor 10 to gear set, forming a transmission hub for angle adjustment.

[0055] First gear 11: Fixed to the outer end of transmission shaft 13, meshing with second gear 12, transmitting the rotational motion of servo motor 10 to transmission rod 9, achieving stable angle adjustment (backlash error ≤0.5mm) through gear meshing.

[0056] Protective cover 5: Fixed to the outside of the rectangular mounting plate 8, the inside of which can accommodate the servo motor 10 (right side) or be empty (left side), to prevent dust and moisture from entering the gear transmission system, and at the same time protect the servo motor from external impact.

[0057] Servo motor 10: Installed inside the right protective cover 5, with its output end fixed to the first gear 11, it drives the gear set to rotate by forward and reverse rotation (speed accuracy ±5rpm) to realize the electric angle adjustment of the forearm placement block 4, and supports stepless speed adjustment within the range of 0-45°.

[0058] Guide groove 14: It is opened on the rear surface of the forearm placement block 4, and the inner wall is slidably connected to the auxiliary rod 2, which provides a guide track for the forward and backward movement of the palm placement block 3, ensuring that there is no tilting during the movement (straightness error ≤0.3mm).

[0059] Auxiliary rod 2: The front end is embedded in the guide groove 14 and the rear end is connected to the palm placement block 3. It transmits the thrust of the electric telescopic rod, so that the palm placement block slides along the forearm axis (stroke 0-5cm) to adapt to different subjects' palm-to-forearm distances.

[0060] Hand placement block 3: It is connected to the forearm placement block 4 via the auxiliary rod 2. The arc groove on the upper surface fits the palm and can move back and forth and adjust the angle synchronously with the forearm placement block to provide support for the palm and avoid muscle tension caused by the arm being suspended in the air.

[0061] Mounting box 6: Fixed to the lower surface of the forearm placement block 4, with an electric telescopic rod installed inside and a rectangular plate 7 connected externally, providing installation space for the position fine-tuning mechanism and ensuring the stable operation of the electric telescopic rod.

[0062] Rectangular plate 7: Connects the telescopic end of the electric telescopic rod to the palm placement block 3, transmitting the linear motion of the telescopic rod to the palm placement block, ensuring that the auxiliary rods 2 on both sides move synchronously, and avoiding the palm tilting or jamming.

[0063] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
