Description

Technical Field

[0001] The present invention relates to sphygmomanometer technology, and particularly to an automatic calibration device and method for a sphygmomanometer. Background Art

[0002] The blood pressure changes in patients with brain diseases such as epilepsy show significant specificity. The mechanism of blood pressure fluctuation involves multiple complex factors such as the disease attack cycle, drug intervention effect, and abnormal neuroregulation. Therefore, strict requirements are imposed on the accuracy and reliability of blood pressure measurement devices. As the core measuring instrument for calibrating the blood pressure of patients, the accuracy of the measurement data of the sphygmomanometer is directly related to the disease diagnosis efficiency, treatment plan optimization, and prognosis evaluation system construction.

[0003] There are various types of commonly used sphygmomanometers, which are widely applicable to the general population. However, for patients with brain diseases such as epilepsy or other special populations, such as strap-type sphygmomanometers and wristband-type sphygmomanometers, they cannot meet the requirements. In contrast, the arm-cylinder type sphygmomanometer can be well applicable to special populations with its more automated operation. When in use, only the arm needs to be placed inside the arm cylinder for automatic blood pressure measurement and calibration. However, for patients with brain diseases such as epilepsy, the blood pressure measurement will play a certain warning role in the onset of their diseases. Therefore, they need to regularly measure their blood pressure in daily life. However, the existing arm-cylinder type sphygmomanometers are not only large in size but also prone to collision with external objects during the process of carrying them out, resulting in inconvenient carrying.

[0024] In this embodiment, a frame groove 3 communicating with the accommodating groove 24 is provided on the sphygmomanometer body 1, and the position and size specification of the frame groove 3 are both adapted to the rotating frame 2; It should be added that the surface of the frame groove 3 away from the accommodating groove 24 is a vertical surface, and when the rotating frame 2 rotates upward to the maximum angle, the rotating frame 2 can be restricted to be in a vertical state.

[0025] In this embodiment, the buckle unit includes a right-angle locking rod 5 provided on the cover plate 25. An entry groove 51 adapted to the right-angle locking rod 5 is formed on the surface of the sphygmomanometer body 1. A moving groove 52 communicating with the entry groove 51 is formed inside the sphygmomanometer body 1. A moving plate 53 is slidably connected to the inner side surface of the moving groove 52. A right-angle rod 54 corresponding to the right-angle locking rod 5 is provided on the moving plate 53. A guiding arc surface 55 is provided on the side of the right-angle rod 54 close to the notch of the entry groove 51. A pressing spring 57 is installed between the moving plate 53 and the inner wall of the moving groove 52. A flat groove is formed on the side surface of the sphygmomanometer body 1. A pushing plate 56 is fixedly connected to the surface of the moving plate 53.

[0026] It should be added that the pressing spring 57 is installed on the side close to the opening of the right-angle locking rod 5. And, the pushing plate 56 is slidably connected to the inner side surface of the flat groove, and the surface of the pushing plate 56 is flush with the outer side surface of the sphygmomanometer body 1. Anti-slip lines are provided on the surface of the pushing plate 56.

[0027] During daily carrying, the measuring arm cylinder 21 and the bracket 22 are both in a state of being received inside the accommodating groove 24. And, the cover plate 25 is connected and fixed to the sphygmomanometer body 1 through the cooperation of the right-angle locking rod 5 and the right-angle rod 54. At this time, the operator can directly carry the sphygmomanometer body 1 out by the handle 28; When in use, the operator manually pushes the pushing plate 56. The movement of the pushing plate 56 drives the right-angle rod 54 to move and separate from the right-angle locking rod 5, so that the rotation of the cover plate 25 is no longer restricted. The operator can rotate the cover plate 25 outwards to open it; After that, the operator rotates the measuring arm cylinder 21 upwards so that it moves synchronously with the bracket 22 to the outside of the accommodating groove 24, and rotates the bracket 22 to separate it from the measuring arm cylinder 21. At this time, the operator can directly put the arm into the measuring arm cylinder 21 and place the elbow on the elbow groove 23 on the bracket 22, and then start the blood pressure test by actively pressing the control button 27; After the measurement is completed, the operator takes out the arm, rotates the bracket to contact with the measuring arm cylinder 21, and then rotates the two synchronously so that the two are received in the accommodating groove 24 again. At this time, the operator rotates the cover plate 25 to make it close to the sphygmomanometer body 1, and drives the right-angle locking rod 5 provided thereon to rotate so that it enters the entry groove 51 and presses against the guiding arc surface 55 on the right-angle rod 54, so that the right-angle rod 54 moves against the deformation force of the pressing spring 57, so that the right-angle locking rod 5 can completely enter the entry groove 51. After that, under the action of the resilience of the pressing spring 57, the right-angle rod 54 moves reversely to reset and restrict the withdrawal of the right-angle locking rod 5.

[0028] Embodiment Two: Please refer to Figure 4, this embodiment provides a technical solution on the basis of the above embodiment: a cavity is formed inside the sphygmomanometer body 1, a rotating shaft 6 is fixedly connected to the side surface of the rotating frame 2, and a return torsion spring 61 is installed between the rotating shaft 6 and the inner wall of the cavity.

[0029] It should be noted that the specification of the return torsion spring 61 is adapted to the actual weights of the measuring arm cylinder 21 and the support 22, so that after the cover plate 25 is opened, the measuring arm cylinder 21 and the support 22 can rotate to the working state under the action of the resilience of the return torsion spring 61.

[0030] Embodiment Three: Please refer to Figure 2 , this embodiment provides a technical solution on the basis of the above embodiment: the position of the support 22 corresponds to that of the measuring arm cylinder 21, and a positioning groove 4 is formed on the sphygmomanometer body 1. The shape and size specifications of the positioning groove 4 are adapted to the support 22, and the positioning groove 4 is used to limit the rotation angle of the support 22. The positioning groove 4 is a top-opening groove body.

[0031] Through the setting of the positioning groove 4, it can stably support the support 22, so that the support 22 and the elbow groove 23 provided thereon can cooperate with the measuring arm cylinder 21 to stably support the operator's arm. At the same time, through the top-opening positioning groove 4, while stably carrying the support 22, it can also limit the rotation of the support 22, so that the support 22 and the measuring arm cylinder 21 can always maintain a stable working state.

[0032] Embodiment Four: Please refer to Figure 5 , this embodiment provides a technical solution on the basis of the above embodiment: a carrying flat groove 7 is formed on the top of the sphygmomanometer body 1 away from the handle 28, a magnetic strip 71 is embedded at the bottom of the carrying flat groove 7, and a metal strip 72 is embedded inside the cover plate 25 close to the carrying flat groove 7.

[0033] It should be noted that the position and specification of the metal strip 72 are adapted to the magnetic strip 71, and when the cover plate 25 rotates to the vertical state, the surface of the cover plate 25 abuts against the bottom surface of the carrying flat groove 7.

[0034] When the cover plate 25 rotates to the vertical state, the metal strip 72 provided thereon is adsorbed together with the magnetic strip 71, so as to play a certain limiting role on the cover plate 25, so that the cover plate 25 will not easily rotate in the reverse direction, so that it can maintain a stable working state.
