[0001] The invention belongs to the technical field of blood pressure meters, in particular to a handheld blood pressure meter. Background Art

[0002] With the development of economy and social progress, people's health awareness is constantly improving, self-care awareness is enhanced, and people's requirements for living environment, personal health care, medical treatment, etc. are getting higher and higher. The handheld blood pressure meter is a mechanical blood pressure meter that uses indirect measurement method. It is easy to use and fast, and is increasingly widely used.

[0003] A patent with publication number CN105147271B discloses a shockproof handheld blood pressure meter. The patent sets a shockproof mechanism to effectively reduce the ability of the structure to transmit vibration, protect the core components, and increase its impact resistance. The shockproof mechanism of the technical solution adopts the basic principle of damping shock absorption, that is, when a solid vibrates, the energy of the solid vibration is dissipated as much as possible in the damping layer, which is called damping shock absorption. Damping refers to an effect of hindering the relative movement of an object and converting the kinetic energy into heat energy or other energy that can be dissipated; reducing the resonance amplitude of the blood pressure meter structure, thereby avoiding structural damage caused by the dynamic stress reaching the limit;

[0004] There are still some problems in the actual application of the above scheme. When the user is testing the blood pressure, the arm of the tester is usually tied with a cuff. At the same time, the air tube on the cuff is installed and connected to the blood pressure meter. Then the air bag is pressed cyclically to cooperate with the air tube to inflate the cuff, so that the cuff is squeezed against the arm of the tester, and then gradually deflated. At the same time, the sound of blood flow or pressure changes in the blood vessels are monitored or observed to determine the blood pressure value. However, during the use of this blood pressure meter, the cuff and the blood pressure meter need to be assembled, and then the cuff is used to tie the person's arm to use it to test the blood pressure. If the cuff is lost, the blood pressure meter will not be able to perform blood pressure testing.

DETAILED DESCRIPTION

[0030] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods. Embodiment 1

[0031] like Figures 1 to 7 As shown, a handheld blood pressure meter according to an embodiment of the present invention comprises a blood pressure meter body 1, a through opening 2 is provided on one side of the blood pressure meter body 1, and the through opening 2 is used to place an arm for testing blood pressure, an air cavity 23 is provided on the inner wall of the through opening 2, a rubber sealing layer 14 is provided on the inner wall of the air cavity 23, a mounting block 6 is installed on one side of the blood pressure meter body 1, a rotating column 7 is rotatably connected to the inner cavity of the mounting block 6, and an air pumping assembly is fixedly connected to one end of the rotating column 7;

[0032] The inflation assembly includes a U-shaped fixed block 8 fixedly connected to one end of the rotating column 7, the inner cavity of the U-shaped fixed block 8 is symmetrically rotatably connected to the first rotating rod 9 and the second rotating rod 13, and the lower end surface of the first rotating rod 9 is fixedly connected to a folding air pump 10, one end of the folding air pump 10 is fixedly connected to the second rotating rod 13, an air inlet 11 is opened at one end of the folding air pump 10, and a one-way valve is arranged in the inner cavity of the air inlet 11.

[0033] Specifically, in the prior art, when a person is testing blood pressure, a cuff is usually used to tie the person's arm, and the air tube on the cuff is connected to the blood pressure meter. Then, the air bag is pressed cyclically to cooperate with the air tube to inflate the cuff, so that the cuff is pressed against the person's arm, and then the air is gradually deflated. At the same time, the blood pressure value is determined by monitoring or observing the sound of blood flow or pressure changes in the blood vessels. However, during the use of this blood pressure meter, the cuff and the blood pressure meter need to be assembled, and then the cuff needs to be tied to the person's arm before the blood pressure can be used for testing. If the cuff is lost, the blood pressure meter will not be able to perform blood pressure testing.

[0034] When the user of the present invention performs blood pressure testing, the user holds the first rotating rod 9 and the second rotating rod 13 to lift the U-shaped fixing block 8, and the U-shaped fixing block 8 drives the rotating column 7 to lift the sphygmomanometer body 1, and then the user passes the arm through the opening 2 and places it in the inner cavity of the sphygmomanometer body 1, and at the same time adjusts the position of the sphygmomanometer body 1 outside the arm. After adjusting the arm position, the user holds the first rotating rod 9 and the second rotating rod 13, and the first rotating rod 9 and the second rotating rod 13 cyclically press the folding air pump 10. When the folding air pump 10 is pressed, the air in the inner cavity of the folding air pump 10 will be squeezed and discharged into the air cavity 23. When the folding air pump 10 pushes the first rotating rod 9 and the second rotating rod 13 to reset, the folding air pump 10 will draw in air through the air inlet 11, and the same steps are repeated multiple times to inject air into the inner cavity of the air cavity 23. , and then the air squeezes the rubber sealing layer 14 to expand, so that the rubber sealing layer 14 can expand and squeeze the arm in the inner cavity of the passage 2, and then squeeze the blood vessels of the arm to block the flow of blood, and then detect the blood pressure of the user's arm, thereby solving the problem that when the user performs blood pressure detection on the existing handheld blood pressure meter, the arm of the test person is usually tied with a cuff, and the air tube on the cuff is installed and connected with the blood pressure meter, and then the air bag is pressed cyclically to cooperate with the air tube to inflate the cuff, so that the cuff squeezes the arm of the test person, and then gradually deflates, and at the same time monitors or observes the sound of blood flow or pressure changes in the blood vessels to determine the blood pressure value. However, during the use of this blood pressure meter, since the cuff and the blood pressure meter need to be assembled, and then the person's arm needs to be tied with the cuff to detect the blood pressure, if the cuff is lost, the blood pressure meter will not be able to perform blood pressure detection.

[0035] like Figure 1 , Figure 4 and Figure 7As shown, a snap-fit ​​fixing assembly 12 is provided at one end of the first rotating rod 9 and the second rotating rod 13, and the snap-fit ​​fixing assembly 12 includes a first connecting block 121 fixedly connected to one end of the first rotating rod 9, and a second connecting block 122 fixedly connected to one end of the second rotating rod 13. Two insertion holes 123 are provided at the lower end of the first connecting block 121, and two plug posts 124 are installed at the upper end of the second connecting block 122, and the two plug posts 124 are provided with card beads 125 on the outside.

[0036] like Figure 1 , Figure 4 and Figure 6 As shown, two rotation grooves 27 are formed on the inner wall of the U-shaped fixing block 8 , and the inner cavities of the two rotation grooves 27 are both rotatably connected with rotation shafts 28 , and one end of one rotation shaft 28 is fixedly connected to the first rotation rod 9 , and one end of the other rotation shaft 28 is fixedly connected to the second rotation rod 13 .

[0037] Specifically, when testing the user, the first rotating rod 9 and the second rotating rod 13 are separated by shifting, so that the first rotating rod 13 drives the plug 124 to move synchronously, and the plug 124 drives the card bead 125 to slide out of the inner cavity of the hole 123, and then the user presses the first rotating rod 9 and the second rotating rod 13 cyclically, and the first rotating rod 9 and the second rotating rod 13 squeeze the folding air pump 10 between them during the pressing process, so that the folding air pump 10 squeezes the air in the inner cavity and injects air into the air cavity 23, and after the air enters the air cavity 23, it squeezes the rubber sealing layer 14 to expand, and then the rubber sealing layer 14 is used to squeeze the user's arm, thereby improving the convenience of using the blood pressure monitor.

[0038] like Figure 1 , Figure 4 and Figure 6 As shown, the rotating shaft 28 is located outside the inner cavity of the rotating groove 27 and is fixedly connected to a fixed disk 29 . A torsion spring 30 is fixedly connected to one end of the fixed disk 29 . One end of the torsion spring 30 is fixedly connected to the inner wall of the rotating groove 27 .

[0039] like Figure 1 , Figure 4 and Figure 7 As shown, one end of the folding air pump 10 is fixedly connected to an air guide tube 22, one end of the air guide tube 22 is fixedly connected to the bottom of the inner cavity of the U-shaped fixing block 8, an air guide hole 24 is opened on the inner wall of the air cavity 23, and the air guide hole 24 is connected to the inner cavity of the rotating column 7.

[0040] Specifically, after the first rotating rod 9 and the second rotating rod 13 are moved to separate, the torsion spring 30 is used to reset the twisted fixed disk 29, and the fixed disk 29 drives the rotating shaft 28 to rotate. At the same time, the rotating shaft 28 drives the first rotating rod 9 and the second rotating rod 13 to expand and flip. Then, the folding air pump 10 is squeezed by cyclically pressing the first rotating rod 9 and the second rotating rod 13, so that the folding air pump 10 squeezes the air into the air guide tube 22. At the same time, the air enters the rotating column 7 and is discharged into the air cavity 23, thereby improving the convenience of using the blood pressure meter.

[0041] like Figures 3 to 5 As shown, a first receiving groove 20 is opened inside one side of the main body 1 of the sphygmomanometer, and a winding rack 19 is rotatably connected to the inner cavity of the first receiving groove 20. A sling 5 is fixedly connected to the outside of the winding rack 19. A plug 21 is fixedly connected to one end of the winding rack 19, and the plug 21 is connected to the air guide hole 24 by plugging.

[0042] like Figure 3 , Figure 4 and Figure 5 As shown, the winding frame 19 is fixedly connected to the rotating column 7, a ratchet 18 is fixedly connected to the outside of the rotating column 7, two grooves 15 are symmetrically provided on the inner wall of one side of the sphygmomanometer body 1, and springs 16 are fixedly connected to the bottom of the inner cavity of the two grooves 15, an insert block 17 is fixedly connected to one end of the spring 16, and the insert block 17 is plugged into the ratchet 18.

[0043] like Figure 1 and Figure 4 As shown, an LED display screen 3 is installed on the upper end surface of the blood pressure meter body 1, two fixing blocks 4 are installed on both sides of the upper end surface of the blood pressure meter body 1, and the two ends of the sling 5 are slidably connected to the inner cavities of the two fixing blocks 4.

[0044] Specifically, when using the sphygmomanometer body 1 to detect blood pressure, the user places the arm through the opening 2 in the inner cavity of the sphygmomanometer body 1, and adjusts the position of the sphygmomanometer body 1 outside the arm. After adjusting the arm position, a small amount of air is injected into the air cavity 23 to expand the rubber sealing layer 14 to fix the user's arm. After fixing the user's arm, the sling 5 is carried obliquely on the user's shoulder, and then the user holds the first rotating rod 9 and the second rotating rod 13 to rotate, and the first rotating rod 9 and the second rotating rod 13 drive the U-shaped fixing block 8 to rotate, and the U-shaped fixing block 8 drives the rotating column 7 to rotate, and the rotating column 7 will drive the ratchet 18 to rotate during the rotation process, and the ratchet 18 drives the winding frame 19 to rotate, so that the winding frame 19 drives the sling 5 to wind up, and then the sling 5 is used to lift the sphygmomanometer body 1 to move upward, so that the sphygmomanometer body 1 belt The user's arm is moved upward and the user's arm is kept at the same horizontal line with the heart to reduce the influence of gravity on the blood pressure measurement value, and then air is continuously injected into the inner cavity of the air cavity 23 to squeeze the rubber sealing layer 14 to expand, so that the rubber sealing layer 14 can expand and squeeze the arm in the inner cavity of the opening 2, and then squeeze the blood vessels of the arm to block the blood flow, and then the blood pressure of the user's arm is detected, and the LED display screen 3 is used to display the detected results, thereby solving the problem that when using the existing handheld blood pressure meter, the person usually needs to sit next to the table and place the arm on the table so that the arm and the person's heart are kept at the same horizontal line, and then air is injected into the cuff to bind the person's arm, and then the air is gradually deflated, while monitoring or observing the blood flow sound or pressure changes in the blood vessels to determine the blood pressure value, which is not only cumbersome to operate, but also greatly limits the use environment of the blood pressure meter. Embodiment 2

[0045] like Figure 1 and Figure 4 As shown, a second receiving groove 25 is provided inside one side of the main body 1 of the sphygmomanometer. A torsion spring winding mechanism 26 is rotatably connected to the inner cavity of the second receiving groove 25 , and the outer portion of the torsion spring winding mechanism 26 is fixedly connected to one end of the sling 5 .

[0046] Specifically, after the blood pressure test of the person is completed, the torsion spring winding mechanism 26 is rotated and reset, and then the torsion spring winding mechanism 26 drives the sling 5 to be wound, thereby improving the convenience of using the blood pressure meter.

[0047] like Figure 1 to Figure 2 As shown, an air leakage hole 31 is opened at one end of the sphygmomanometer body 1, an air leakage valve 32 is arranged in the inner cavity of the air leakage hole 31, and the air leakage hole 31 is communicated with the air cavity 23.

[0048] Specifically, when the blood pressure is tested, the air vent 31 is opened by twisting the air vent valve 32, and the air in the air cavity 23 is slowly discharged through the air vent 31, so that the LED display screen 3 is used to display the blood flow sound or pressure change in the blood vessel to determine the blood pressure value.

[0049] Working principle: when the user performs blood pressure detection, the user holds the first rotating rod 9 and the second rotating rod 13 to pick up the U-shaped fixing block 8, and the U-shaped fixing block 8 drives the rotating column 7 to pick up the sphygmomanometer body 1, and then the user passes the arm through the through-port 2 and places it in the inner cavity of the sphygmomanometer body 1, and at the same time adjusts the position of the sphygmomanometer body 1 outside the arm. After adjusting the position of the arm, the user holds the first rotating rod 9 and the second rotating rod 13, and the first rotating rod 9 and the second rotating rod 13 cyclically press the folding air pump 10. When the folding air pump 10 is pressed, the air in the inner cavity of the folding air pump 10 is squeezed and discharged into the air cavity 23. When the folding air pump 10 pushes the first rotating rod 9 and the second rotating rod 13 to reset, the folding air pump 10 draws in air through the air inlet 11. The same steps are repeated for multiple times to inject air into the inner cavity of the air cavity 23, so that the air squeezes the rubber sealing layer 14 to expand, so that the rubber sealing layer 14 can expand and squeeze the arm in the inner cavity of the through-port 2, and then squeeze the blood vessels of the arm to block the flow of blood.

[0050] When the blood pressure is tested, the air leakage hole 31 is opened by twisting the air leakage valve 32, and the air in the air cavity 23 is slowly discharged through the air leakage hole 31, so that the blood flow sound or pressure change in the blood vessel is displayed by the LED display screen 3 to determine the blood pressure value;

[0051] When the sphygmomanometer body 1 is used for blood pressure detection, the user places the arm through the opening 2 into the inner cavity of the sphygmomanometer body 1, and adjusts the position of the sphygmomanometer body 1 outside the arm. After adjusting the position of the arm, a small amount of air is injected into the air cavity 23 to expand the rubber sealing layer 14 to fix the user's arm. After the user's arm is fixed, the sling 5 is carried obliquely on the user's shoulder, and then the user holds the first rotating rod 9 and the second rotating rod 13 to rotate, and the first rotating rod 9 and the second rotating rod 13 drive the U-shaped fixing block 8 to rotate, and the U-shaped fixing block 8 drives the rotating column 7 to rotate, and the rotating column 7 drives the ratchet 18 to rotate during the rotation process. The ratchet 18 drives the winding frame 19 to rotate, and the winding frame 19 drives the sling 5 to wind up, and then the sling 5 is used to lift the sphygmomanometer body 1 and move it upward, so that the sphygmomanometer body 1 drives the user's arm to move upward, and the user's arm and heart are kept at the same horizontal line to reduce the influence of gravity on the blood pressure measurement value, and then air is continuously injected into the inner cavity of the air cavity 23 again to squeeze the rubber sealing layer 14 to expand, so that the rubber sealing layer 14 can expand and squeeze the arm in the inner cavity of the opening 2, and then squeeze the blood vessels of the arm to block the blood flow, and then the blood pressure of the user's arm is tested, and the LED display screen 3 is used to display the test results.
