DETAILED DESCRIPTION

[0037] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0038] See also Figure 1 to Figure 9 As an embodiment of the utility model, the surrounding opening and closing sphygmomanometer comprises an instrument body 1, a servo air pump (not shown in the figure) is integrated in the instrument body 1, and a mesh cover is also arranged on the outer wall of the instrument body 1, and the mesh cover is connected to the air inlet end of the servo air pump;

[0039] The instrument body 1 is also provided with an openable and closable arm-tube measuring assembly, which includes a measuring body 4 mounted on the instrument body 1, on which is formed an excellent ring portion 403, which is in an excellent arc shape; a movable ring 5 is coaxially arranged around the excellent ring portion 403, and the movable ring 5 is in a semicircular shape. When one end of the movable ring 5 rotates around and fits with one end of the excellent ring portion 403, the two form a closed arm-tube structure;

[0040] An inflatable airbag 6 is fixedly provided on the inner wall of the optimal ring part 403, and the airbag 6 is connected to the air outlet end of the servo air pump; after the movable ring 5 and the optimal ring part 403 form a closed arm tube structure, the servo air pump inflates the airbag 6; and after the air in the airbag 6 is completely discharged, one end of the movable ring 5 rotates around to be flush with the other end of the optimal ring part 403, so as to form an open half-arm tube structure.

[0041] The arm tube structure in the utility model can be opened and closed by rotating around, and cooperates with the inflation and deflation of the airbag 6 to achieve inflation after the arm tube structure is completely closed, and the arm tube structure can be opened around after the air in the airbag 6 is completely exhausted. Therefore, it has a double protection effect. If the air in the airbag 6 cannot be exhausted, the movable ring 5 can be opened by rotating around to remove the measuring limb from the equipment. If the movable ring 5 fails such as getting stuck, the airbag 6 can be deflated to loosen the measuring limb, thereby reducing the risk that the measuring limb cannot be removed from the equipment after a failure of the equipment.

[0042] As a further solution of the utility model, an arc-shaped accommodating cavity 404 is provided inside the superior ring portion 403, the accommodating cavity 404 is concentric with the superior ring portion 403, the accommodating cavity 404 is connected to one end of the superior ring portion 403, and the end of the superior ring portion 403 connected to the accommodating cavity 404 forms an inlet and outlet;

[0043] The movable ring 5 is slidably matched with the accommodating cavity 404 so that the movable ring 5 and the superior ring portion 403 are coaxially arranged.

[0044] Because the accommodating cavity 404 is concentric with the superior ring portion 403, and the movable ring 5 is slidably matched with the accommodating cavity 404, the movable ring 5 can slide coaxially with the superior ring portion 403 and be arranged around. In addition, because the superior ring portion 403 is an excellent arc shape and the movable ring 5 is a semicircular shape, no matter how the movable ring 5 rotates around, it will not be separated from the superior ring portion 403.

[0045] As a further solution of the utility model, a protrusion 501 is integrally provided at the inner center of the movable ring 5, and an elastic pad 502 is fixedly provided on the protrusion 501;

[0046] The airbag 6 is fixedly arranged on both sides of the inner side of the superior ring portion 403, and when the airbag 6 is filled with air, the airbag 6 and the elastic pad 502 form a concentric and isodiametric annular structure;

[0047] An arc-shaped notch 405 is provided at the center of the inner side of the superior ring portion 403 . The notch 405 is connected to the accommodating cavity 404 and passes through the inlet and outlet ends.

[0048] By using the protruding part 501 and the elastic pad 502, the movable ring 5 and the superior ring part 403 form a closed arm tube structure, and the airbag 6 and the elastic pad 502 can form a concentric and diametric ring structure to elastically cover and constrain the test limb. By using the notch 405, when the movable ring 5 rotates around, the protruding part 501 will not interfere with the superior ring part 403.

[0049] As a further solution of the utility model, a housing 8 is fixedly installed on the outside of the superior ring part 403, and a gear 9 is rotatably arranged inside the housing 8;

[0050] A plurality of teeth are fixedly provided on the outer wall of the movable ring 5, and the plurality of teeth are evenly distributed along the outer wall of the movable ring 5 to form an arc-shaped toothed belt 503;

[0051] The superior ring portion 403 is also provided with a through opening 406, and the gear 9 passes through the through opening 406 and meshes with the toothed belt 503;

[0052] A servo motor 10 is installed outside the housing 8 , the servo motor 10 is connected to the gear 9 via a shaft, and the servo motor 10 communicates with a servo air pump.

[0053] The servo motor 10 drives the gear 9 to rotate. During the rotation of the gear 9, the movable ring 5 is driven to rotate in a circle by cooperating with the toothed belt 503, so as to control the movable ring 5 to move coaxially with the superior ring part 403 to form an open half-arm tube structure or a closed arm tube structure.

[0056] When measurement is required, the electronic valve opens and the servo air pump works to pump air through the air channel 401 of the electronic valve box; the air in the air channel 401 enters the airbag 6 through the air nozzle 7, causing the airbag 6 to expand to be concentric and have the same diameter as the elastic pad 502, and then the electronic valve closes.

[0057] After the measurement is completed, the electronic valve is reopened, and the airbag 6 elastically contracts, so that the air in the airbag 6 enters the servo air pump through the air nozzle 7, the air channel 401, the electronic valve, and the air outlet of the servo air pump, and is finally discharged from the air inlet of the servo air pump.

[0058] As a further solution of the utility model, a control switch 11 is elastically mounted on one end of the superior ring part 403 opposite to the inlet and outlet end, and a control system host (not shown in the figure) is also integrated in the instrument body 1, and the control system host communicates with the connection port 102 provided on the instrument body 1;

[0059] The measuring body 4 is also provided with a docking port 402 for communicating with the control switch 11 , and the docking port 402 is adapted to the connecting port 102 .

[0060] When the servo motor 10 drives the movable ring 5 to close until one end of the movable ring 5 conflicts with one end of the superior ring part 403, the end of the movable ring 5 will trigger the control switch 11, and the control switch 11 will send a signal to the connection port 102 through the docking port 402. After the signal is transmitted to the control system host, the control system host will send a pumping signal to the servo air pump.

[0061] As a further solution of the present invention, an arm support 3 is further provided on the instrument body 1, and the arm support 3 is provided on one side of the arm-tube type measuring assembly.

[0062] The forearm extending through one side of the arm tube type measuring assembly is supported and lifted by the provided arm support 3.

[0063] As a further solution of the utility model, a display screen 2 is also provided on the instrument body 1, and the display screen 2 is connected to an air pressure sensor (not shown in the figure) provided in the air bag 6 for displaying various blood pressure indexes.

[0064] The display screen 2 can display the high blood pressure value, low blood pressure value, pulse, heart rate and other parameters of the measured person, which can be used as a reference for the measured person to judge the blood pressure health status.

[0065] The above embodiments are exemplary rather than restrictive, so without departing from the spirit or basic features of the present invention, the technical solutions of the present invention that can be implemented in other specific forms are all included in the present invention.
