[0027] Blood pressure monitors are a common medical device widely used in clinical and home health monitoring. Their measurement accuracy is directly related to the user's health assessment and treatment decisions, and the tightness of the cuff is a key factor in ensuring measurement accuracy. Currently, the method for detecting blood pressure monitor cuff leaks is to inflate the cuff until the air pressure inside reaches the test pressure and then observe the pressure change to determine whether there is a leak. However, this inflation process is typically slow, resulting in low detection efficiency and making it difficult to meet the needs of large-scale production or rapid testing.
[0028] The following is combined with Figure 1-4The embodiments of the present application will be described in detail.
[0029] like Figure 1 and Figure 2 As shown, a blood pressure cuff leakage test tool comprises:
[0030] The test mount 1 is provided with an extrusion slot 11 for accommodating a blood pressure cuff;
[0031] The air pump assembly 2 is used to connect to the cuff interface of the blood pressure cuff and inflate the blood pressure cuff through the cuff interface until it is squeezed against the inner wall of the squeezing groove 11.
[0032] Specifically, an extrusion groove 11 is provided downwardly on the upper surface of the test mount 1. The shape of the extrusion groove 11 is designed according to the shape and specifications of the blood pressure cuff to ensure that after the blood pressure cuff is inflated, the inner wall of the extrusion groove 11 can fully contact and squeeze the blood pressure cuff. The test mount 1 is designed as a stable base structure, usually made of metal or high-strength plastic, to ensure that the test mount 1 does not shake or tilt during the test. The blood pressure cuff is placed in the extrusion groove 11, and the air pump assembly 2 is arranged on the outside of the test mount 1. The air pump assembly 2 inflates the blood pressure cuff through the cuff interface. The blood pressure cuff is limited by the space of the extrusion groove 11 and cannot be freely inflated, which causes the air pressure in the blood pressure cuff to rise rapidly, so as to quickly reach the air pressure required for the test, thereby improving the test efficiency.
[0033] In some embodiments, as Figure 1 and Figure 3 As shown, the extrusion groove 11 includes a first extrusion groove 111, which is a cylindrical groove for accommodating a folded blood pressure cuff. The folded blood pressure cuff is a cylindrical structure formed by curling the blood pressure cuff along its length direction.
[0034] In addition, the extrusion groove 11 further includes a second extrusion groove 112 , which is an annular groove for accommodating a non-foldable blood pressure cuff. The non-foldable blood pressure cuff is a blood pressure cuff with a fixed annular structure.
[0035] Specifically, the first extrusion groove 111 is designed to be cylindrical, and its diameter and depth are determined according to the size of the folding blood pressure cuff to ensure that the folding blood pressure cuff in its uninflated state can be placed in the first extrusion groove 111, and the folding blood pressure cuff in its inflated state can be squeezed by the groove wall of the first extrusion groove 111. The second extrusion groove 112 is designed to be annular, and its groove width is adapted to the thickness of the non-folding blood pressure cuff to ensure that the non-folding blood pressure cuff in its uninflated state can be placed in the second extrusion groove 112, and the non-folding blood pressure cuff in its inflated state can be squeezed by the groove wall of the first extrusion groove 111, so that the air pressure of the blood pressure cuff can quickly reach the required test pressure.
[0036] In this embodiment, the first extrusion groove 111 is used for a foldable cuff, and the second extrusion groove 112 is used for a non-foldable cuff, which increases the compatibility of the test tool with different types of blood pressure cuffs, making the test tool suitable for blood pressure cuffs of various models and types, greatly improving the versatility of the test tool.
[0037] In some embodiments, the first extrusion groove 111 is located inside the second extrusion groove 112 , and an annular column 12 is formed between the first extrusion groove 111 and the second extrusion groove 112 .
[0038] In addition, a second photoelectric sensor is installed on the wall of the extrusion groove 11 to detect whether the blood pressure cuff is installed in the extrusion groove 11.
[0039] Specifically, the sidewall of the annular column 12 is provided with a first receiving groove 15 extending therethrough. A pair of first receiving grooves 15 are provided, symmetrically arranged along the central axis of the first extrusion groove 111. Each first receiving groove 15 houses a second photoelectric sensor, which is a through-beam type and is used to detect whether a foldable blood pressure cuff is inserted into the first extrusion groove 111. The wall of the second extrusion groove 112 is provided with a second receiving groove 16. A pair of second receiving grooves 16 are provided, symmetrically arranged along the central axis of the second extrusion groove 112. Each second receiving groove 16 houses a second photoelectric sensor, which is a through-beam type and is used to detect whether a non-foldable blood pressure cuff is inserted into the second extrusion groove 112. The projection of the first receiving groove 15 onto the second receiving groove 16 coincides with the projection of the second receiving groove 16, ensuring that the signal emitted by the through-beam type photoelectric sensor installed in the second receiving groove 16 can smoothly pass through the first receiving groove 15, thereby realizing the signal transmission and reception function, thereby detecting whether a non-foldable blood pressure cuff is inserted into the second extrusion groove 112.
[0040] In this embodiment, first extrusion slot 111 is positioned within second extrusion slot 112. This nested design saves installation space for the test fixture, making the test fixture more compact and improving its portability. A photoelectric sensor is installed within extrusion slot 11 to detect whether the blood pressure cuff is properly installed. The precise detection of the photoelectric sensor reduces human interference and improves the accuracy of the test results.
[0041] In some embodiments, as Figure 1 and Figure 2 As shown, the air pump assembly 2 includes an air pump 21, a connecting joint 22 and a connecting pipe 23. The connecting joint 22 is connected between the interface of the air pump 21 and the connecting pipe 23. The connecting pipe 23 is connected to the cuff interface of the blood pressure monitor cuff.
[0042] In addition, the air pump assembly 2 further includes a pressure relief valve 24 and an air pressure sensor 25 , and both the pressure relief valve 24 and the air pressure sensor 25 are connected to the connecting joint 22 .
[0043] Specifically, the connecting joint 22 is a four-way joint, which is respectively connected to the air pump 21, the pressure relief valve 24, the connecting pipe 23 and the air pressure sensor 25, so that the air flow flows between the components. The pressure relief valve 24 can control the deflation process. After the sphygmomanometer cuff test is completed, the pressure relief valve 24 can make the air flow in the sphygmomanometer cuff flow out quickly, ensuring the efficiency of the entire test process. The air pressure sensor 25 can monitor the air pressure changes in the sphygmomanometer cuff in real time, and is used to determine whether there is air leakage in the sphygmomanometer cuff and provide accurate data support. During the process of the air pressure sensor 25 monitoring the air pressure in the cuff, the branch between the air pump 21 and the four-way joint is closed, and at the same time, the branch between the pressure relief valve 24 and the four-way joint is closed to avoid air pressure leakage in the sphygmomanometer cuff, which is conducive to the air pressure sensor 25 to accurately detect the air pressure in the sphygmomanometer cuff.
[0044] In this embodiment, a connecting joint 22 connects the air pump 21, pressure relief valve 24, connecting tube 23, and air pressure sensor 25, respectively, to control the flow of air between the various components. The air pressure sensor 25 is connected to the connecting tube 23 via the connecting joint 22, and the connecting tube 23 is connected to the blood pressure monitor cuff interface, allowing the air pressure sensor 25 to accurately monitor changes in air pressure within the cuff in real time. The pressure relief valve 24 is connected to the cuff interface via the connecting joint 22, allowing air to quickly escape from the blood pressure monitor cuff after testing is complete, ensuring the efficiency of the entire testing process.
[0045] In some embodiments, as Figure 2 、 Figure 3 and Figure 4 As shown, the test mount 1 is provided with a connecting pipe 13 and a connecting air path 14 , the connecting air path 14 is connected between the cuff interface on the blood pressure monitor cuff and the connecting pipe 13 , and the connecting pipe 13 is inserted into the pipe mouth of the connecting pipe 23 .
[0046] In addition, the test fixture is provided with a mounting groove 131 , the connecting pipe 13 is installed at the bottom of the mounting groove 131 , and a first photoelectric sensor is installed on the groove wall of the mounting groove 131 to detect whether the connecting pipe 23 is connected to the connecting pipe 13 .
[0047] Specifically, the connecting air path 14 is provided inside the test mounting seat 1 to facilitate the connection between the blood pressure cuff interface and the connecting tube 13. The connecting tube 13 is a connecting joint used to connect the pipe mouth of the connecting tube 23 and the connecting air path 14. The connecting air path 14 can be divided into two paths according to the situation, respectively used to connect the cuff interface of the foldable blood pressure cuff in the first extrusion groove 111 and the cuff interface of the non-foldable blood pressure cuff in the second extrusion groove 112. The test fixture is provided with a mounting groove 131. The connecting tube 13 is installed at the bottom of the mounting groove 131 and its bottom is connected to the connecting air path 14. A first photoelectric sensor is installed on the side wall of the mounting groove 131. The first photoelectric sensor is a reflective photoelectric sensor. The photoelectric sensor is used to accurately detect whether the connecting tube 13 is inserted into the pipe mouth of the connecting tube 23 to avoid leakage of the blood pressure cuff due to incomplete insertion of the connecting tube 13 or insertion with position deviation.
[0048] Based on the same inventive concept, the present application also discloses a blood pressure cuff leakage testing system, including the above-mentioned testing tool;
[0049] a testing module connected to the air pressure sensor 25, configured to control the air pressure sensor 25 to collect air pressure data within the blood pressure cuff at preset time intervals and calculate an air pressure leakage rate based on the air pressure data; the testing module is further configured with an alarm unit that triggers an alarm to alert an operator when the air pressure leakage rate exceeds a preset threshold;
[0050] The host computer platform is connected to the test module to display the air pressure data, air pressure leakage rate and alarm status in the blood pressure cuff in real time, and provide data storage and analysis functions.
[0051] Specifically, the test module includes a microprocessor and a storage unit. The microprocessor is responsible for processing data from the air pressure sensor 25, performing calculations, and controlling the triggering of the alarm unit. The storage unit is used to store test parameters such as preset time intervals and air pressure leakage rate thresholds, as well as historical test data. Based on the collected air pressure data, the test module can calculate the air pressure leakage rate, a key indicator for evaluating the sealing performance of the cuff. The calculation method may involve linear regression, differentiation, or other statistical methods to ensure the accuracy and reliability of the results. The alarm unit includes components such as a relay, a buzzer, and an LED indicator. When the air pressure leakage rate exceeds the preset threshold, the alarm unit emits an alarm signal such as sound and light to alert the operator. The host computer platform includes a computer. The test module transmits data to the host computer platform via a serial port and a CAN bus. The data is displayed in real time to display the air pressure data, air pressure leakage rate, and alarm status within the blood pressure monitor cuff, allowing the operator to intuitively understand the test progress and results. The computer is equipped with data analysis tools for generating trend charts and statistical reports to help the operator better understand the changing patterns of cuff performance.
[0052] In this embodiment, the blood pressure cuff leakage test system forms an efficient and accurate test system by integrating the test tooling, test modules and host computer platform, which is suitable for the scenario of large-scale blood pressure cuff leakage testing.
[0053] The blood pressure cuff leakage test process in this application is as follows:
[0054] Cuff installation: Install the blood pressure cuff into a suitable extrusion groove 11 (first extrusion groove 111 or low-temperature extrusion groove 11 ), connect the blood pressure cuff interface with the connecting air path 14 , and then insert the mouth of the connecting tube 23 outside the connecting tube 13 .
[0055] Installation detection: After the blood pressure cuff is installed in the extrusion groove 11 and the tube end of the connecting tube 23 is inserted outside the connecting tube 13, the reflected photoelectric sensor and the refractive photoelectric sensor work simultaneously to confirm whether the blood pressure cuff is installed in place and whether the tube end of the connecting tube 23 is correctly connected to the connecting tube 13.
[0056] Inflation process: After the blood pressure cuff is installed, the pressure relief valve 24 is closed, and the air pump 21 starts to quickly inflate the blood pressure cuff. The inflation will continue until the preset pressure value (300 mmHg). After reaching this pressure, the air pump 21 stops inflating.
[0057] Pressure monitoring and data recording: After the air pressure is completed, the test module controls the pressure sensor to collect the current air pressure value first. After 5 seconds, the test module will control the pressure sensor to collect the current air pressure value again. The test module automatically calculates the leakage rate of the blood pressure cuff through the two air pressure values.
[0058] Test Result Processing: If the test result fails (the leak rate exceeds the set threshold), the test module automatically uploads the test data to the host computer and sounds an alarm to alert the operator. Simultaneously, the pressure relief valve 24 opens and rapidly deflates the cuff, ensuring that the gas in the cuff is quickly discharged. If the test passes, the data is also uploaded to the host computer to confirm the accuracy of the test result, and the deflation operation is also performed.
[0059] Result upload and system management: All test data will eventually be uploaded to the host computer through the serial port interface for later viewing, archiving and analysis.
[0060] The beneficial effects presented by the technical solution of the present invention are as follows:
[0061] Significantly improve test efficiency: Compared with traditional manual testing or testing methods that rely on blood pressure linear machines, the present invention uses testing tooling to enable the blood pressure cuff to quickly reach the air pressure required for testing, which not only greatly reduces the time required, but also reduces the dependence on frequent manual operations. It is particularly suitable for large-scale rapid testing scenarios, thereby effectively saving time and labor costs.
[0062] Enhanced accuracy of test results: The test fixture of the present invention integrates advanced equipment such as a through-beam photoelectric sensor, a refractive photoelectric sensor, and a high-precision air pressure sensor 25, ensuring the effective connection between the blood pressure cuff and the air pump 21, and detecting the air pressure changes inside the blood pressure cuff in real time, thereby minimizing human errors and improving the accuracy of the test results.
[0063] Improved Compatibility: The design of this test fixture fully considers the diversity of blood pressure cuffs on the market. It is compatible not only with traditional foldable cuffs but also with integrally molded (non-foldable) cuffs, significantly enhancing the tool's versatility. This feature overcomes the cuff type limitations of traditional testing equipment and better meets the testing needs of a wide range of blood pressure monitor products.
[0064] Optimize user operation experience: Through highly automated control and simple operation procedures, the test system of the present invention greatly improves the user's operation convenience. The operator only needs to simply install the blood pressure cuff on the test tooling and start the test. The system can automatically complete the detection, data recording and uploading work. The operation is intuitive and simple, which greatly reduces the complexity of manual intervention and improves overall work efficiency.
[0065] Ensure repeatable and reliable test results: Thanks to its precise automated control system, the system completes each test under consistent conditions, ensuring highly repeatable test results. Strict inflation and deflation control procedures effectively eliminate the impact of environmental factors and operator differences on test results, ensuring data stability and reliability.
[0066] Supports automatic data recording and remote management: This system supports data transmission via serial ports and CAN buses, enabling real-time upload of test data to a host computer system for subsequent data review, archiving, and analysis. Furthermore, the system supports multi-device cascade management, enabling efficient integration of multiple test devices to meet the needs of large-scale testing tasks, making the testing process more systematic and standardized.
[0067] Reduced labor and resource costs: Automated testing, recording, and data upload systems significantly reduce the need for manual operations and ease the workload for operators. Testers only need to perform simple equipment operations, and the system automatically completes the entire testing process, effectively avoiding human interference, saving labor costs, and reducing resource waste.
[0068] Strong adaptability: The automated testing tooling of this invention fully meets the needs of rapid and accurate leak detection for large numbers of blood pressure cuffs on production lines, making it particularly suitable for large-scale production and after-sales repair of blood pressure monitors. Its efficiency and accuracy ensure that every product undergoes standardized, error-free testing during mass production, thus guaranteeing stable and reliable product quality.
