[0028] Various implementations of the present invention are described below with reference to the accompanying drawings. These implementations are merely exemplary and are not intended to limit the present invention.

[0029] An embodiment of the present invention provides a portable blood pressure monitor with a self-checking function. Figure 1 FIG. 1 is a schematic diagram of a portable blood pressure monitor 1 according to an embodiment of the present invention.

[0030] In at least one embodiment of the present application, Figure 1 As shown, the portable blood pressure monitor 1 comprises a cuff 11, a storage portion 12, and a main body 13. The storage portion 12 is used to store the cuff 11. The inflation volume of the cuff 11 is limited by the space within the storage portion 12. The main body 13 includes an inspection unit (not shown), which is connected to the cuff 11 via an air tube 14. This inspection unit controls the inflation or deflation of the cuff 11 stored in the storage portion 12, thereby enabling self-inspection of the portable blood pressure monitor 1.

[0031] It is well known in the art that when performing self-inspection on a blood pressure monitor, an external component with an air-holding function is required. According to the above embodiment, the space in the storage portion 12 that holds the cuff 11 is used to limit the amount of air in the cuff 11. The cuff 11, with its limited inflation volume, acts as an air-holding component for self-inspection (calibration) of the blood pressure monitor, thereby enabling self-inspection (calibration) of the blood pressure monitor. This allows for timely tracking of the blood pressure monitor's measurement accuracy, providing a more accurate basis for the user's self-diagnosis and treatment. In addition, after the blood pressure measurement, the cuff is stored in the storage portion, solving the problem of having nowhere to store the cuff after the blood pressure measurement, thereby improving the user experience.

[0032] In the embodiment of the present application, a cuff is taken as an example as the air containing component, but the present application is not limited thereto. The air containing component may also be an air tank or other components with air containing function.

[0033] Figure 2 FIG. 1 is another schematic diagram of the portable blood pressure monitor 1 according to an embodiment of the present invention.

[0034] In the embodiments of this application, Figure 2As shown, the component with air storage function is realized as an air tank 112, which is connected to the inspection part (not shown) in the main body 13 through the air tube 14. The air volume of the air tank 112 is, for example, 10cc (cubic centimeters) to 500cc. Similarly, the air tank 112 can also be accommodated in the storage part of the portable blood pressure monitor 1 (in Figure 2 (not shown) in the figure, the portable blood pressure monitor 1 is self-inspected by the inspection unit while the air tank 112 is stored.

[0035] In at least one embodiment of the present application, Figure 1 As shown, L represents the length of the storage portion 12, H represents the height of the highest point of the storage portion 12, a represents the thickness of the cuff 11 after stacking, and W represents the length of the storage portion 12 in the thickness direction of the cuff 11 after stacking. Then, the length W of the storage portion 12 in the thickness direction of the cuff 11 after stacking is calculated by the following formula (1):

[0036] W=V / (L×H)+a (1)

[0037] Here, V represents the maximum air volume of the cuff 11 when confined by the storage portion 12. For example, the ideal maximum inflation value of the cuff 11 is 100cc. It is worth noting that the maximum inflation volume V of the cuff 11 when confined by the storage portion 12 is different from the maximum inflation volume V' of the cuff 11. V' is the maximum inflation volume of the portable blood pressure monitor 1 when performing the blood pressure measurement function. Generally speaking, V ≤ V'.

[0038] Thus, the amount of air in the cuff 11 during the self-check function can be limited by the space size of the storage portion 12, so that the cuff 11 with the limited amount of air inflated can function as an air storage member for self-checking (calibrating) the blood pressure monitor.

[0039] In the embodiment of the present application, the main body 13 may further include a blood pressure measuring unit (not shown), that is, to realize the blood pressure measurement function of an ordinary sphygmomanometer.

[0040] In order to separate the blood pressure measurement function and the spot check function of the blood pressure meter of the present application, in one embodiment, for example, Figure 1 As shown, a switch button 131 may be provided on the main body 13 , and the switch button 131 is connected to the spot inspection part and the blood pressure measurement part, and is used to switch the sphygmomanometer 1 between spot inspection and blood pressure measurement.

[0041] For example, in the power-on standby state, the blood pressure monitor 1 is directly in the blood pressure measurement function. Click the switch button 131 once, and the blood pressure monitor 1 is in the self-inspection function. Click the switch button 131 again, and the blood pressure monitor switches back to the blood pressure measurement function. The embodiments of the present application are not limited to this. For example, the self-inspection function of the blood pressure monitor 1 can be triggered by long pressing or double-clicking the switch button 131, and then switching back to the blood pressure measurement function by single clicking or the like.

[0042] Similarly, in order to separate the blood pressure measurement function and the inspection function of the sphygmomanometer, in another embodiment, for example, a inspection button (not shown) can be directly provided on the main body 13, and the inspection button is connected to the above-mentioned inspection part to start the self-inspection function of the inspection part.

[0043] For example, in the power-on standby state, the blood pressure monitor 1 is directly in the blood pressure measurement function. Clicking the inspection button once activates the self-inspection function of the blood pressure monitor 1, and clicking the inspection button again activates the blood pressure measurement function of the blood pressure monitor 1. The embodiments of the present application are not limited to this. For example, the self-inspection function of the blood pressure monitor 1 can be triggered by long pressing or double-clicking the inspection button, and then the blood pressure measurement function can be started by single-clicking or other methods.

[0044] Through the above two implementation methods, the blood pressure measurement function and self-checking function of the blood pressure monitor are clear at a glance, and the different functions of the blood pressure monitor can be implemented clearly and explicitly.

[0045] In at least one embodiment of the present application, in order to make the user more clear about the inspection status and / or results, in one embodiment, Figure 1 As shown, an indicator light 132 may be provided on the main body 13 , and the indicator light 132 is connected to the inspection part. The indicator light 132 is used to indicate the status and / or results of the inspection of the portable blood pressure monitor 1 .

[0046] For example, during the inspection process, the indicator light 132 is indicated by a yellow flash. After the inspection is completed and the portable blood pressure monitor 1 is indicated as qualified, the indicator light 132 is indicated by a green flash. After the inspection is completed and the portable blood pressure monitor 1 is indicated as unqualified, the indicator light 132 is indicated by a red flash. Of course, the indicator light 132 can also be used to indicate the status and / or results of the blood pressure measurement of the portable blood pressure monitor 1. In addition, the number of indicator lights 132 is not limited to Figure 1 As shown in FIG1 , for example, the number of indicator lights 132 can also be set according to the number of indicators to be actually detected, that is, one inspection indicator corresponds to one indicator light (as described in the inspection method below).

[0047] In another embodiment, Figure 1As shown, a display unit 133 is provided on the main body 13 . The display unit 133 is connected to the inspection unit and is used to display the status and / or results of the inspection of the portable blood pressure monitor 1 .

[0048] For example, the display unit 133 can use numbers, letters, or text to indicate the inspection process and results. For example, the number 1 indicates that the inspection is in progress, the number 2 indicates that the inspection result is qualified, and the number 3 indicates that the inspection result is unqualified. Of course, the display unit 133 can also be used to display the status and / or results of the blood pressure measurement of the portable blood pressure monitor 1.

[0049] By using the above two embodiments, or by having both the indicator light 132 and the display unit 133, the user can clearly see the inspection status and / or results, achieving the purpose of effective early warning, thereby improving the user experience. In addition, different warning sounds can be used to indicate the inspection and / or blood pressure measurement status and / or results of the portable blood pressure monitor 1, thereby meeting the needs of different user groups.

[0050] Figure 3 and Figure 4 This is another schematic diagram of the portable blood pressure monitor according to an embodiment of the present application, showing that the storage portion is located at different positions of the main body.

[0051] In the embodiments of this application, Figure 1 As shown, the storage portion 12 can be located at the rear of the main body 13, or as shown in FIG. Figure 3 As shown, the storage portion 12 may also be located at the bottom of the main body 13, or as shown in FIG. Figure 4 As shown, the storage portion 12 may also be located on the side of the main body 13 .

[0052] Thus, the storage portion 12 can be set at a suitable position according to needs and functions.

[0053] In an embodiment of the present application, the above-mentioned inspection unit includes a control unit, and an air pump and an exhaust valve connected to the control unit. The cuff 11 is connected to the air pump of the inspection unit through an air tube 14. In addition, the above-mentioned inspection unit may also include two sensors (for example, air pressure sensors), which are connected to the above-mentioned control unit. The control unit determines whether the accuracy of the two sensors meets the requirements based on the signals fed back by the two sensors.

[0054] Therefore, the inspection department can evaluate the pressurizing capacity of the air pump, the air tightness of the entire air system, and the controllability of the exhaust valve, and can interactively verify the accuracy of the sensor.

[0055] The above only describes the structure related to the blood pressure monitor of the embodiment of the present application. The present application is not limited to this. For example, the main body 13 of the portable blood pressure monitor 1 of the embodiment of the present application may also include a storage unit, etc. The storage unit can be used to store previous blood pressure measurement values ​​and standard values ​​(described in the inspection method below).

[0056] The following describes the self-inspection method of the portable blood pressure monitor 1 in detail through the self-inspection process of the blood pressure monitor.

[0057] Figure 5 1 is a schematic diagram of a self-checking method for a portable blood pressure monitor 1 according to an embodiment of the present invention. In the process of the method, the cuff 11 is used as an air receiving component for example.

[0058] like Figure 5 As shown, the self-inspection method of the portable blood pressure monitor 1 includes:

[0059] 501, fold the cuff 11 and place it in the storage portion 12, then click the check button (or click the switch button 131 to switch the blood pressure monitor 1 to the self-check function);

[0060] In this step, the indicator light 132 (eg, LED light) starts to flash yellow.

[0061] 502, the control unit of the inspection unit issues a command to close the exhaust valve;

[0062] 503, the control unit issues an instruction to the air pump to increase the pressure, and records the pressurization time T1 of the air pump from 0 to 280 mmHg, for example;

[0063] In this step, the air pressure sensor can detect the real-time pressure value, and the display unit 133 can display the real-time pressure value according to the feedback from the air pressure sensor.

[0064] 504, the control unit determines whether the pressurization time T1 is less than or equal to the standard pressurization time T0 stored in the storage unit (T1 ≤ T0?); if the judgment result is no, the process proceeds to inspection conclusion ①; if the judgment result is yes, the process proceeds to 505;

[0065] In this step, the pressurization time of 0-280mmHg can be used to evaluate whether the air pump's pressurization capacity meets the requirements. Inspection conclusion ① indicates that the pressurization test result is unqualified. At this time, the indicator light 132 lights up red, and the inspection process ends. If the judgment result is qualified, the indicator light 132 can light up green (for example, the green light is on for 2 seconds). After lighting up green for 2 seconds, the indicator light 132 turns yellow and flashes, indicating that the next indicator is to be inspected. In addition, if the judgment result is no, the green light can also be turned off, and the indicator light will continue to flash yellow until all indicators are tested, and then the light color will change.

[0066] 505, the control unit issues a command to lock the air pump for a predetermined period of time (i.e., in a holding state);

[0067] In this step, for example, the air pump is kept in a hold state for 10 seconds. When the control unit issues this instruction, the indicator light 132 flashes yellow.

[0068] 506 , the control unit records the pressure value P1 of the air pump at the beginning of the predetermined time and the pressure value P1′ of the air pump after the predetermined time has passed, and calculates the pressure difference ΔP1 (ΔP1=P1−P1′) after the predetermined time has passed.

[0069] In this step, if the inspection unit includes two air pressure sensors, one is a main sensor and the other is a secondary sensor, the above method may further include 506', in which the control unit further records the pressure value P of the main sensor after the predetermined time has passed. 主 And the pressure value P of the auxiliary sensor 副 , and calculate the difference ΔP between the pressure value of the main sensor and the pressure value of the auxiliary sensor 器 (ΔP 器 =P 主 -P 副 ).

[0070] 507, the control unit determines whether the time pressure difference ΔP1 is less than or equal to the standard time pressure difference ΔP stored in the storage unit. 漏标准 (ΔP1≤ΔP 漏标准 ? ); If the judgment result is no, then proceed to inspection conclusion ②; if the judgment result is yes, then proceed to 508;

[0071] In this step, the degree of air leakage is calculated based on the air pressure change displayed on the display unit 133 for 10 seconds, and it is determined whether the requirements are met. That is, it is evaluated whether the airtightness of the air system meets the requirements.

[0072] In addition, when the inspection unit includes two air pressure sensors, the control unit can also determine the difference ΔP in this step. 器 Is it less than or equal to the standard device pressure difference ΔP stored in the storage unit? 器标准 (ΔP 器 ≤ΔP 器标准 ? ), that is, the control unit determines whether the time pressure difference ΔP1 is less than or equal to the standard time pressure difference ΔP stored in the storage unit. 漏标准 (ΔP1≤ΔP 漏标准 ? ), and the difference ΔP 器 Is it less than or equal to the standard device pressure difference ΔP stored in the storage unit? 器标准 (ΔP 器 ≤ΔP 器标准? ). After determining that ΔP1>ΔP 漏标准 and / or ΔP 器 >ΔP 器标准 , then we can enter the inspection conclusion ②, if it is judged that ΔP1≤ΔP 漏标准 And ΔP 器 ≤ΔP 器标准 , then enter 508.

[0073] Inspection conclusion ② indicates that the leakage and / or instrument difference test results are unqualified. At this time, the indicator light 132 lights up red, ending the inspection process; if the judgment result is qualified, the indicator light 132 can light up green (for example, the green light is on for 2 seconds). After lighting up the green light for 2 seconds, the indicator light 132 turns to flashing yellow, indicating that the next indicator should be inspected. In addition, if the judgment result is qualified, the green light may not be on, and the indicator light may continue to flash yellow until all indicators are tested, and then the color of the light will be changed.

[0074] 508, the control unit issues a command to lock the air pump, and at the same time, the exhaust valve starts exhausting air at a slow speed, so that the pressure value drops from 280 mmHg to 100 mmHg, for example;

[0075] 509, the control unit calculates the slow exhaust time T2 when the pressure value drops from 280 mmHg to 100 mmHg;

[0076] 510, the control unit determines whether the slow exhaust time T2 is less than the slow exhaust time upper limit T stored in the storage unit. 上 and is greater than the lower limit T of the slow exhaust time stored in the storage unit 下 (T 下 <T2<T 上 ? ); If the judgment result is no, then go to inspection conclusion ③; if the judgment result is yes, then go to 511;

[0077] In this step, the exhaust valve's controllability during slow exhaust is evaluated by measuring the time it takes to slowly exhaust the air from 280 mmHg to 100 mmHg.

[0078] Inspection conclusion ③ indicates that the test result of the slow exhaust control is unqualified. At this time, the indicator light 132 lights up red, and the inspection process ends. If the judgment result is qualified, the indicator light 132 may light up green (for example, the green light is on for 2 seconds). After lighting up the green light for 2 seconds, the indicator light 132 turns to yellow flashing, indicating that the next indicator should be inspected. In addition, if the judgment result is qualified, the green light may not be on, and the indicator light may continue to flash yellow until all indicators are tested, and then the color of the light will be changed.

[0079] 511, the control unit issues a command to fully open the exhaust valve to enter a rapid exhaust state, so that the pressure value drops from 100 mmHg to 0 mmHg, for example;

[0080] 512, the control unit calculates the rapid exhaust time T3 when the pressure value drops from 100 mmHg to 0 mmHg;

[0081] 513, determine whether the rapid exhaust time T3 is less than or equal to the standard rapid exhaust time T stored in the storage unit. 急排标准 (T3≤T 急排标准 ? ); if the judgment result is no, then enter the inspection conclusion ④; if the judgment result is yes, then enter the inspection conclusion ⑤;

[0082] In this step, the control capability of the exhaust valve during rapid exhaust is evaluated by the time it takes to rapidly exhaust from 100 mmHg to 0 mmHg.

[0083] Inspection conclusion ④ indicates that the test result of rapid exhaust control is unqualified, at this time the indicator light 132 lights up red, and the inspection process ends; inspection conclusion ⑤ indicates that the inspection is completed and the test indicators are qualified, at this time the indicator light 132 lights up green.

[0084] The portable blood pressure monitor with self-checking function of the embodiment of the present application limits the inflation volume of the cuff 11 by the space of the storage portion 12 for storing the cuff 11. The cuff 11 with limited inflation volume acts as an air-receiving component for self-checking (calibrating) the blood pressure monitor, thereby achieving self-checking (calibrating) the blood pressure monitor. This allows timely tracking of the blood pressure monitor's measurement accuracy, providing a more accurate basis for the user's self-diagnosis and treatment.
