[0020] As a common medical device, sphygmomanometers are widely used in clinical and home health monitoring. The measurement accuracy is directly related to the assessment of the user's health status and treatment decisions, and the airtightness of the cuff is one of the key factors to ensure the measurement accuracy. Currently, the common method for detecting air leakage in a sphygmomanometer cuff is to inflate the cuff until the air pressure inside the cuff reaches the test air pressure, and to judge whether there is an air leakage phenomenon by observing the change in air pressure. However, this inflation process is usually relatively slow, resulting in low detection efficiency and difficult to meet the requirements of large-scale production or rapid detection.

[0021] The following combines the attached Figures 1-4 to detail the embodiments of the present application.

[0022] As Figure 1 and Figure 2 shown, a leak test tooling for a sphygmomanometer cuff includes: Test mounting base 1, provided with a squeezing groove 11 for accommodating a sphygmomanometer cuff; Air pump assembly 2, used to connect with the cuff interface of the sphygmomanometer cuff and inflate the sphygmomanometer cuff through the cuff interface until it is squeezed against the inner wall of the squeezing groove 11.

[0023] Specifically, a squeezing groove 11 is opened downward on the upper surface of the test mounting base 1. The shape of the squeezing groove 11 is designed according to the shape and specifications of the sphygmomanometer cuff to ensure that after the sphygmomanometer cuff is inflated, the inner wall of the squeezing groove 11 can make full contact and squeeze with the sphygmomanometer cuff. The test mounting base 1 is designed as a stable base structure, usually made of metal or high-strength plastic, to ensure that the test mounting base 1 does not shake or tilt during the test. The sphygmomanometer cuff is placed in the squeezing groove 11, and the air pump assembly 2 is arranged outside the test mounting base 1. The air pump assembly 2 inflates the sphygmomanometer cuff through the cuff interface. The sphygmomanometer cuff is restricted by the space of the squeezing groove 11 and cannot inflate and expand freely, resulting in a rapid increase in the air pressure inside the sphygmomanometer cuff to quickly reach the air pressure required for testing, thereby improving the test efficiency.

[0024] In some embodiments, as Figure 1 and Figure 3 shown, the squeezing groove 11 includes a first squeezing groove 111, and the first squeezing groove 111 is a cylindrical groove for accommodating a folded sphygmomanometer cuff, and the folded sphygmomanometer cuff is a cylindrical structure formed by curling the sphygmomanometer cuff along its length direction.

[0025] In addition, the squeezing groove 11 further includes a second squeezing groove 112, and the second squeezing groove 112 is an annular groove for accommodating a non-foldable sphygmomanometer cuff, and the non-foldable sphygmomanometer cuff is a sphygmomanometer cuff with a fixed annular structure.

[0026] Specifically, the first squeezing groove 111 is designed as a cylinder, and its diameter and depth need to be determined according to the size of the folded sphygmomanometer cuff to ensure that the folded sphygmomanometer cuff in the non-inflated state can be placed in the first squeezing groove 111, and the folded sphygmomanometer cuff in the inflated state can be squeezed by the groove wall of the first squeezing groove 111. The second squeezing groove 112 is designed as an annular shape, and its groove width is adapted to the thickness of the non-foldable sphygmomanometer cuff to ensure that the non-foldable sphygmomanometer cuff in the non-inflated state can be placed in the second squeezing groove 112, and the non-foldable sphygmomanometer cuff in the inflated state can be squeezed by the groove wall of the first squeezing groove 111, so that the air pressure of the sphygmomanometer cuff can quickly reach the required test air pressure.

[0027] In this embodiment, the first extrusion groove 111 is for the foldable cuff, and the second extrusion groove 112 is for the non-foldable cuff, which increases the compatibility of the test tooling with different types of sphygmomanometer cuffs, enabling the test tooling to be applicable to various models and types of sphygmomanometer cuffs, and greatly improving the versatility of the test tooling.

[0028] In some embodiments, the first extrusion groove 111 is located within the second extrusion groove 112, and an annular column 12 is formed between the first extrusion groove 111 and the second extrusion groove 112.

[0029] In addition, a second photoelectric sensor is installed on the groove wall of the extrusion groove 11 to detect whether the sphygmomanometer cuff is installed in the extrusion groove 11.

[0030] Specifically, a through first placement groove 15 is provided on the side wall of the annular column 12. There are a pair of first placement grooves 15, which are symmetrically arranged along the center axis of the first extrusion groove 111. Each first placement groove 15 is provided with a second photoelectric sensor, and this second photoelectric sensor is a transmissive photoelectric sensor for detecting whether the folded sphygmomanometer cuff is placed in the first extrusion groove 111. Second placement grooves 16 are provided on the groove wall of the second extrusion groove 112. There are a pair of second placement grooves 16, which are symmetrically arranged along the center axis of the second extrusion groove 112. Each second placement groove 16 is provided with a second photoelectric sensor, and this second photoelectric sensor is a transmissive photoelectric sensor for detecting whether the non-foldable sphygmomanometer cuff is placed in the second extrusion groove 112. The projection of the first placement groove 15 onto the second placement groove 16 coincides with the second placement groove 16, ensuring that the signal emitted by the transmissive photoelectric sensor installed in the second placement groove 16 can pass through the first placement groove 15 smoothly, thereby realizing the signal transceiver function to detect whether the non-foldable sphygmomanometer cuff is placed in the second extrusion groove 112.

[0031] In this embodiment, the first extrusion groove 111 is arranged within the second extrusion groove 112. This nested design can save the installation space of the test tooling, make the structure of the test tooling more compact, and improve the portability of the test tooling. A photoelectric sensor is installed in the extrusion groove 11 to detect whether the sphygmomanometer cuff is installed in the extrusion groove 11. Through the precise detection of the photoelectric sensor, the interference of human factors is reduced, and the accuracy of the detection result is improved.

[0032] In some embodiments, as Figure 1 and Figure 2 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, and the connecting pipe 23 communicates with the cuff interface of the sphygmomanometer cuff.

[0033] In addition, the air pump assembly 2 further includes a pressure relief valve 24 and a pressure sensor 25, and both the pressure relief valve 24 and the pressure sensor 25 are communicated with the connection joint 22.

[0034] Specifically, the connection joint 22 is a four-way joint, and the four-way joint is respectively connected to the air pump 21, the pressure relief valve 24, the connecting pipe 23 and the pressure sensor 25 to allow air flow to flow between the components. The pressure relief valve 24 can control the air release process. After the blood pressure cuff test is completed, the pressure relief valve 24 can cause the air flow in the blood pressure cuff to flow out quickly, ensuring the efficiency of the entire test process. The pressure sensor 25 can monitor the air pressure change in the blood pressure cuff in real time, be used to judge whether there is an air leakage phenomenon in the blood pressure cuff, and provide accurate data support. During the process of monitoring the air pressure in the cuff by the pressure sensor 25, 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 blood pressure cuff, which is beneficial to the pressure sensor 25 to accurately detect the air pressure in the blood pressure cuff.

[0035] In this embodiment, the connection joint 22 is respectively connected to the air pump 21, the pressure relief valve 24, the connecting pipe 23 and the pressure sensor 25 to control the air flow to flow between the components. The pressure sensor 25 is communicated with the connecting pipe 23 through the connection joint 22, and the connecting pipe 23 is connected to the cuff interface of the blood pressure monitor, so that the pressure sensor 25 can monitor the air pressure change in the cuff in real time and accurately. The pressure relief valve 24 is communicated with the cuff interface through the connection joint 22, so that the internal air flow can flow out quickly after the blood pressure cuff test is completed, ensuring the efficiency of the entire test process.

[0036] In some embodiments, as Figure 2 、 Figure 3 and Figure 4 shown, a connecting pipe 13 and a connecting air path 14 are provided on the test mounting base 1, and the connecting air path 14 is communicated between the cuff interface on the blood pressure cuff and the connecting pipe 13, and the connecting pipe 13 is inserted into the pipe orifice of the connecting pipe 23.

[0037] In addition, an installation groove 131 is provided on the test tooling, the connecting pipe 13 is installed at the bottom of the installation groove 131, and a first photoelectric sensor is installed on the groove wall of the installation groove 131 to detect whether the connecting pipe 23 is connected to the connecting pipe 13.

[0038] Specifically, the communication air path 14 is opened inside the test mounting base 1 to facilitate the connection between the sphygmomanometer cuff interface and the communication pipe 13. The communication pipe 13 is a connecting joint for connecting the pipe orifice of the connecting pipe 23 and the communication air path 14. The communication air path 14 can be divided into two paths according to the situation, which are respectively used to connect the cuff interface of the foldable sphygmomanometer cuff in the first extrusion groove 111 and the cuff interface of the non-foldable sphygmomanometer cuff in the second extrusion groove 112. An installation groove 131 is provided on the test tooling. The communication pipe 13 is installed at the bottom of the installation groove 131 and its bottom is communicated with the communication air path 14. A first photoelectric sensor is installed on the side wall of the installation groove 131. The first photoelectric sensor is a reflective photoelectric sensor, which is used to accurately detect whether the communication pipe 13 is inserted into the pipe orifice of the connecting pipe 23, so as to avoid air leakage of the sphygmomanometer cuff caused by incomplete insertion or positional deviation of the communication pipe 13.

[0039] Based on the same inventive concept, the present application also discloses a sphygmomanometer cuff air leakage test system, including the above-mentioned test tooling; A test module, connected to the pressure sensor 25, is used to control the pressure sensor 25 to collect the air pressure data in the sphygmomanometer cuff at a preset time interval, and calculate the air pressure leakage rate based on the air pressure data. The test module is also configured with an alarm unit, which triggers an alarm to remind the operator when the air pressure leakage rate exceeds a preset threshold; An upper computer platform, connected to the test module, is used to display the air pressure data, air pressure leakage rate and alarm status in the sphygmomanometer cuff in real time, and provide data storage and analysis functions.

[0040] Specifically, the test module includes a microprocessor and a storage unit. The microprocessor is responsible for processing the data from the pressure sensor 25, performing calculation tasks, and controlling the trigger 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, which is a key indicator for evaluating the sealing performance of the cuff. The calculation method may involve linear regression, difference 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 alarm signals such as sound and light to remind the operator to pay attention. The upper computer platform includes a computer. The test module transmits data to the upper computer platform through a serial port and a CAN bus to display the air pressure data, air pressure leakage rate and alarm status in the sphygmomanometer cuff in real time, enabling the operator to intuitively understand the test progress and results. The computer is equipped with data analysis tools for generating trend charts, statistical reports, etc., to help the operator better understand the change law of the cuff performance.

[0041] In this embodiment, the blood pressure cuff air leakage test system forms an efficient and accurate test system by integrating a test tooling, a test module, and a host computer platform, which is applicable to the scenario of mass testing of blood pressure cuff air leakage.

[0042] The blood pressure cuff air leakage test process in this application is as follows: Cuff installation: Install the blood pressure cuff into the appropriate extrusion groove 11 (the first extrusion groove 111 or the low-temperature extrusion groove 11), connect the blood pressure cuff interface to the communication air path 14, and then insert the nozzle of the connecting tube 23 outside the communication tube 13.

[0043] Installation in-place detection: After the blood pressure cuff is installed in the extrusion groove 11 and the nozzle of the connecting tube 23 is inserted outside the communication tube 13, the transmissive photoelectric sensor and the refractive photoelectric sensor work simultaneously to confirm whether the blood pressure cuff is installed in place and whether the nozzle of the connecting tube 23 is correctly connected to the communication tube 13.

[0044] 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 air pressure value (300 mmHg) is reached. After reaching this air pressure, the air pump 21 stops inflating.

[0045] Pressure monitoring and data recording: After the air pressure is completed, the test module controls the pressure sensor to first collect the current air pressure value. Five seconds later, the test module will again control the pressure sensor to collect the current air pressure value. The test module automatically calculates the leakage rate of the blood pressure cuff through the two air pressure values.

[0046] Test result processing: If the test result is unqualified (the leakage rate exceeds the set threshold), the test module will automatically upload the test data to the host computer and emit an alarm sound to remind the operator. At the same time, the pressure relief valve 24 will open to quickly deflate, ensuring that the gas in the cuff is quickly discharged. If the test is qualified, the data will also be uploaded to the host computer to confirm the accuracy of the test result, and the deflation operation will also be performed.

[0047] Result uploading and system management: All test data will ultimately be uploaded to the host computer through the serial port interface for easy later viewing, archiving, and analysis.

[0048] The beneficial effects presented by the technical solution of the present invention are as follows: Significantly improve the test efficiency: Compared with the traditional manual detection or the detection method relying on the blood pressure linear machine, the present invention enables the blood pressure cuff to quickly reach the required air pressure for testing through the test tooling, not only greatly reducing the required time but also reducing the dependence on frequent manual operations. It is especially suitable for large-scale rapid detection scenarios, thus effectively saving time and labor costs.

[0049] Enhance the accuracy of test results: The test tooling in the present invention integrates advanced devices such as opposed photoelectric sensors, refractive photoelectric sensors, and high-precision barometric pressure sensors 25, ensuring the effective connection between the sphygmomanometer cuff and the air pump 21, and real-time detecting the air pressure change inside the sphygmomanometer cuff, minimizing human error and improving the precision of test results.

[0050] Improve compatibility: The design of the test tooling in the present invention fully considers the diversity of sphygmomanometer cuffs on the market. It is not only compatible with traditional foldable cuffs but also applicable to one-piece molded (non-foldable) cuffs, significantly enhancing the versatility of the tooling. This feature breaks the limitation of traditional detection equipment in terms of cuff types and better meets the detection requirements of diverse sphygmomanometer products.

[0051] Optimize the user operation experience: Through highly automated control and a simple operation process, the test system in the present invention greatly improves the operation convenience for users. The operator only needs to simply install the sphygmomanometer cuff onto the test tooling and start the test, and the system can automatically complete the detection, data recording, and uploading tasks. The operation is intuitive and simple, greatly reducing the complexity of manual intervention and improving the overall work efficiency.

[0052] Ensure the repeatability and reliability of test results: Thanks to the precise automated control system, the system of the present invention can complete each test under consistent conditions, thus ensuring a high degree of repeatability of test results. The strict air charging and discharging control process effectively eliminates the influence of environmental factors and operator differences on test results, guaranteeing the stability and reliability of data.

[0053] Support automatic data recording and remote management: The present invention supports data transmission through the serial port and CAN bus, and can upload test data to the host computer system in real time for subsequent data viewing, archiving, and analysis. At the same time, the system supports multi-device cascaded management, can efficiently integrate multiple test devices, adapt to the needs of large-scale detection tasks, and make the detection process more systematic and standardized.

[0054] Reduce labor and resource costs: The automated detection, recording, and data uploading system significantly reduces the need for manual operations and alleviates the work burden of operators. The test personnel only need to perform simple equipment operations, and the system can automatically complete the entire detection process, effectively avoiding the interference of human factors, saving labor costs, and reducing resource waste.

[0055] Strong adaptability: The automated test tooling of the present invention can fully meet the requirements of quickly and accurately detecting air leakage of a large number of sphygmomanometer cuffs in the production line, and is particularly suitable for large-scale production and after-sales maintenance scenarios of sphygmomanometers. Its high efficiency and accuracy ensure that each product can be tested in a standardized and error-free manner during mass production, thus guaranteeing the stable and reliable quality of the products.
