Description

Technical Field

[0001] This utility model relates to the field of blood pressure monitor technology, and in particular to a blood pressure monitor synchronous calibration structure. Background Technology

[0002] A blood pressure monitor is a Class II medical device that measures arterial blood pressure. By measuring systolic and diastolic blood pressure, it assesses cardiovascular health, assists in the diagnosis of diseases such as hypertension and hypotension, and directly reflects core physiological indicators such as vascular resistance and cardiac pumping function. Some devices can also monitor pulse rate simultaneously, providing a complete picture of the basic cardiovascular condition. Calibration of the blood pressure monitor is a key means to ensure its long-term accurate operation. Essentially, it corrects system errors in the equipment through standardized procedures, ensuring that the deviation between the measured value and the actual blood pressure value conforms to medical standards.

[0003] A search revealed Chinese Patent Publication No. CN213189532U, which discloses a novel blood pressure calibration instrument, relating to the field of medical device technology. Specifically, the novel blood pressure calibration instrument includes a testing platform. The upper surface of the testing platform is provided with a limit post, a baffle, and an anti-slip pad. The interior of the testing platform is provided with a power supply, a controller, a processor, and an air pump. A control panel is fixedly connected to the front of the testing platform, and a support base is fixedly connected to the lower surface of the testing platform. This novel blood pressure calibration instrument improves detection quality and facilitates fixation through the use of limiting posts and baffles. The power supply and adapter enhance operational safety and enable self-powering, expanding its application range. The control panel facilitates operation and observation. The controller and processor make it easy to move and carry. However, this patent has significant drawbacks. When the battery is inserted, uneven force can cause tilting or hard collisions with the contacts, leading to contact deformation and preventing a complete fit. When the device vibrates or the blood pressure monitor shifts slightly during calibration, the battery can loosen in the battery compartment, causing the electrodes to lose contact or experience intermittent contact. This directly leads to power supply fluctuations, affecting the normal operation of the sensing and data processing modules and causing distorted measurement data. Utility Model Content

[0036] Specifically, the outer surface of the substrate 521 is slidably fitted with the outer surface of the guide rod 422, and the end is fixed to the adjustment cylinder 421. When the adjustment cylinder 421 is started, it can drive the substrate 521 to slide along the guide rod 422 in an oriented manner. The protrusions 523 on the inner wall of the guide groove 522 are arranged in a specific direction, which can force the battery to be placed in the corresponding positive and negative directions, thus avoiding incorrect electrode connection from the source.

[0037] Please see the appendix Figure 6 To be continued Figure 10 The rotating plate assembly 533 includes a rotating shaft 5331, with a rotating plate 5332 rotatably connected to the outer surface of the rotating shaft 5331.

A spiral spring 5337 is fixedly connected to the outer surface of the rotating shaft 5331, and a fixing sleeve 5334 is sleeved on the outer surface of the spiral spring 5337. A tape reel 5335 is fixedly connected to the end of the rotating shaft 5331, and a connecting belt 5336 is fixedly connected to the inner wall of the tape reel 5335. The outer surface of the connecting belt 5336 is movably connected to the surface of the tape reel 5335. The secondary pressing assembly 534 includes a secondary pressure rod 5341, with the end of the secondary pressure rod 5341... A telescopic component 5342 is fixedly connected to the main body. An inner spring 5343 is sleeved on the outer surface of the telescopic component 5342. A connecting rod 5344 is fixedly connected to the outer surface of the secondary pressure rod 5341. The outer surface of the rotating shaft 5331 rotates with the inner wall of the partition plate 532. The outer surfaces of the first-layer rotating plate 5332 and the second-layer rotating plate 5333 are movably connected with the inner wall of the partition plate 532 and the outer surface of the rubber sleeve 514. The outer surface of the connecting rod 5344 is fixed with the end of the connecting belt 5336. The outer surfaces of the secondary pressure rod 5341 and the connecting rod 5344 slide with the inner wall of the partition plate 532. The outer surface of the fixed sleeve 5334 is fixed with the inner wall of the partition plate 532. The ends of the telescopic component 5342 and the inner spring 5343 are fixed with the inner wall of the partition plate 532.

[0038] Specifically, the outer surface of the rotating shaft 5331 is rotatably connected to the inner wall of the partition plate 532 to ensure smooth rotation without jamming; the spiral spring 5337 fixed on its outer surface is sleeved in the fixed sleeve 5334, and the outer surface of the fixed sleeve 5334 is fixed to the inner wall of the partition plate 532, which not only restricts the displacement of the spiral spring 5337, but also provides a fixed reference for its power storage and reset. The end of the rotating shaft 5331 is fixed to the winding drum 5335. When the rotating plate rotates, it drives the winding drum 5335 to rotate synchronously. The connecting strip 5336 fixed on the inner wall of the winding drum 5335 is released accordingly, providing tensile power to the secondary pressing assembly 534 and realizing power linkage.

[0039] Working principle: The pre-treated blood pressure monitor is placed back-side up on the workpiece positioning plate 414. After the equipment is started, the calibration parameters are preset on the display 2. The adapter battery is placed into the guide groove 522 of the pad component 52 in the battery mounting mechanism 5. The protrusions 523 on the inner wall of the guide groove 522 not only distinguish the positive and negative terminals of the battery through a specific arrangement to avoid incorrect electrode connection, but also play a limiting role to prevent the battery from accidentally falling into the depth of the guide groove 522. The protrusions 524 assist in positioning the battery. Then the battery mounting mechanism 5 takes the lead in operation. The base plate 521 of its pad component 52 slides along the guide rod 422 under the drive of the adjusting cylinder 421 in the pressing component 42 of the calibration mechanism 4. The connecting block 531 drives the guide component 53 to move synchronously, so that the execution component 51 is accurately positioned. Aligning with the blood pressure monitor's battery compartment, the partition plate 431 of the lifting component 43 of the calibration mechanism 4 moves downward along the guide rod 422. The bottom mounting base 434 drives the filling block 511 of the actuator 51 to approach. The multiple battery pressure rods 512 fixed to the filling block 511 correspond to the batteries in the guide groove 522. Under the driving force of the lifting cylinder 433, the battery begins to be pressed down. During the pressing process, the battery first contacts the surface of the first rotating plate 5332 of the rotating plate assembly 533 of the guide component 53. The first rotating plate 5332 is squeezed by the battery and rotates along the rotating shaft 5331 until it fits against the inner wall of the partition plate 532. During this period, the second rotating plate 5333, which is at a 70° angle with the first rotating plate 5332, rotates synchronously. When the battery passes the axis position of the rotating shaft 5331, the surface of the second rotating plate 5333 and the battery pressure rods... The rubber sleeve 514 outside the end of the 512 extension pin 513 contacts the surface of the 512 extension pin. At the same time, the rotating shaft 5331 rotates, driving the end winding drum 5335 to rotate synchronously. The winding drum 5335 releases the connecting belt 5336. The connecting belt 5336 pulls the connecting rod 5344 of the secondary pressing assembly 534, causing the secondary pressing rod 5341 to move down along the inner wall of the partition plate 532 until the battery is completely pressed into the battery compartment of the blood pressure monitor. At this time, the secondary pressing rod 5341 presses the battery under the downward pull of the connecting belt 5336, realizing secondary pressing to prevent the battery from making a false contact. After that, the docking pressurizing component 412 of the calibration mechanism 4 vents air into the blood pressure monitor to simulate human blood pressure, and the monitoring camera 3 captures the data on the panel. After a single measurement, the air pressure unloading component 413 unloads the residual air pressure. The equipment repeats the measurement a preset number of times. The display 2 compares multiple sets of data from multiple blood pressure monitors. If an abnormality is found, the battery mounting mechanism 5 and the calibration mechanism 4 work together. The adjusting cylinder 421 fine-tunes the position of the base plate 521 to correct the docking deviation. The lifting cylinder 433 adjusts the height of the partition plate 431 to stabilize the battery power supply. The rotating plate assembly 533 uses the elastic force of the spiral spring 5337 to fine-tune the contact pressure to assist in calibration. After the calibration is qualified, the lifting cylinder 433 moves the partition plate 431 upward, and the battery pressure rod 512 moves upward and resets simultaneously. The spiral spring 5337 on the outer surface of the rotating shaft 5331 releases elastic potential energy to drive the rotating shaft 5331 to rotate in the opposite direction. The first-layer rotating plate 5332 and the second-layer rotating plate 5333 then reset to the inner wall of the partition plate 532. At the same time, the tape reel 5335 retracts the connecting tape 5336.Under the combined action of the telescopic component 5342 at its end and the inner retraction spring 5343 on its outer surface, the secondary pressure rod 5341, with the elastic restoring force of the inner retraction spring 5343 and the telescopic guidance of the telescopic component 5342, drives the connecting rod 5344 to return to its synchronous position. This achieves the synchronous return of the secondary pressure assembly 534 and the rotating plate assembly 533, allowing the operator to remove the blood pressure monitor.
