Therefore, the distance between the first detection part and the second detection part is reduced, and the first detection part and the second detection part clamp the arm, so that the blood pressure can be accurately measured.

[0012] When the measurement is completed, the air bag is deflated, the air bag is contracted, the first horizontal part of the first clamping arm moves downward, thereby rotating the first horizontal part counterclockwise downward relative to the shaft, and the first detection part rotates counterclockwise upward relative to the shaft; the second horizontal part of the second clamping arm moves upward, thereby rotating the second horizontal part clockwise upward relative to the shaft, and the second detection part rotates clockwise downward relative to the shaft. Therefore, the distance between the first detection part and the second detection part is increased, and the user can move the arm out.

[0013] In an alternative embodiment, both ends of the air bag are provided with connecting structures, which are respectively fixedly connected with the first horizontal part and the second horizontal part.

[0014] Beneficial effects: by arranging the connecting structures at both ends of the air bag, the air bag is connected with the first clamping arm and the second clamping arm, and the connecting structures are respectively fixedly connected with the first horizontal part and the second horizontal part, so that the first clamping arm and the second clamping arm are not easily separated from the air bag when the air bag is inflated and expanded.

[0015] When measuring blood pressure, the arm can be placed at the second detection part, and then the air bag is inflated, the air bag expands after inflation, the connecting structure at the upper end of the air bag moves with the expansion of the air bag, driving the first horizontal part of the first clamping arm to move upward, thereby rotating the first horizontal part clockwise upward relative to the shaft, the second inclined part is arranged so that the plane of the first detection part is higher than the horizontal plane of the shaft, so that the first detection part rotates counterclockwise downward relative to the shaft; the connecting structure at the lower end of the air bag moves with the expansion of the air bag, driving the second horizontal part of the second clamping arm to move downward, thereby rotating the second horizontal part counterclockwise downward relative to the shaft, the fourth inclined part is arranged so that the plane of the second detection part is higher than the horizontal plane of the shaft, so that the second detection part rotates counterclockwise upward relative to the shaft.

[0025] In an alternative embodiment, the first detection part and / or the second detection part is horizontally arranged.

[0026] Beneficial effects: By arranging the first detection part and / or the second detection part horizontally, when the user needs to measure blood pressure, the user only needs to place the arm on the second detection part.

[0043]

[0044] ​​The cuff is an important part of the sphygmomanometer, and is particularly important for blood pressure testing. In use, the traditional sphygmomanometer cuff needs to be sleeved at the brachial artery of the upper arm. The user cannot complete the wearing of the sphygmomanometer cuff by himself alone. When the user uses it, it is likely that the blood pressure cannot be measured or accurate blood pressure data cannot be measured due to the fact that the cuff is not tied in place.

[0045] The embodiments of the present application are described below in conjunction with Figures 1 to 6

[0046] According to the embodiments of the present application, in one aspect, a cuff structure of a sphygmomanometer is provided, comprising a gas bag 1, a first clamping arm 2 and a second clamping arm 3.

[0047] The gas bag 1 has an air inlet 101; the first end of the first clamping arm 2 is connected to the first end of the gas bag 1, and the second end of the first clamping arm 2 is a first detection part 201 adapted to contact the arm 6; the second clamping arm 3 has a second detection part 301 arranged opposite to the first detection part 201, the second detection part 301 is adapted to contact the arm 6, and the first clamping arm 2 and the second clamping arm 3 can rotate relative to each other; when the gas bag 1 is inflated, the distance between the first detection part 201 and the second detection part 301 decreases, and when the gas bag 1 is deflated, the distance between the first detection part 201 and the second detection part 301 increases.

[0048] In this embodiment, when blood pressure needs to be measured, the arm 6 can be placed at the second detection part 301, and then the gas bag 1 is inflated. After the gas bag 1 is inflated, it expands, driving the first clamping arm 2 and the second clamping arm 3 to rotate relative to each other, the distance between the first detection part 201 and the second detection part 301 decreases, and the first detection part 201 and the second detection part 301 clamp the arm 6, so that the blood pressure can be accurately measured. When the measurement is completed, the gas bag 1 is deflated, the first clamping arm 2 and the second clamping arm 3 rotate relative to each other, the distance between the first detection part 201 and the second detection part 301 increases, and the user can remove the arm 6. The cuff structure can be inflated or deflated by the user with one hand, so that the cuff structure can clamp the arm 6 by himself alone, thereby accurately measuring the blood pressure.

[0049] It should be noted that the first detection part 201 and the second detection part 301 can be provided with a plurality of sensors for measuring blood pressure.

[0050] In one embodiment, the second clamping arm 3 is hinged to the first clamping arm 2.

[0051] ​In this embodiment, the first clamping arm 2 and the second clamping arm 3 are hinged, so that the relative rotation between the first clamping arm 2 and the second clamping arm 3 can be achieved, and the structure is more simple and compact. When the blood pressure needs to be measured, the arm 6 can be placed at the second detection part 301, and then the air bag 1 is inflated. After the air bag 1 is inflated, the air bag 1 is expanded, and the first clamping arm 2 and the second clamping arm 3 are relatively rotated, the distance between the first detection part 201 and the second detection part 301 is reduced, and the first detection part 201 and the second detection part 301 clamp the arm 6, so that the blood pressure can be accurately measured. When the measurement is completed, the air bag 1 is deflated, the first clamping arm 2 and the second clamping arm 3 are relatively rotated, the distance between the first detection part 201 and the second detection part 301 is increased, and the user can move the arm 6. The sleeve clamp structure, the user can inflate or deflate the air bag 1 with one hand, so that the sleeve clamp structure can clamp the arm 6 by itself, so that the blood pressure can be accurately measured.

[0052] Specifically, in one embodiment, a fixed support can be provided, and the second clamping arm 3 is fixedly arranged on the fixed support, that is, the position of the second clamping arm 3 is fixed, and the first clamping arm 2 is hinged with the second clamping arm 3 to achieve the relative rotation between the first clamping arm 2 and the second clamping arm 3. When the blood pressure needs to be measured, the arm 6 can be placed at the second detection part 301, and then the air bag 1 is inflated. After the air bag 1 is inflated, the air bag 1 is expanded, and the first clamping arm 2 is relatively rotated relative to the second clamping arm 3, the distance between the first detection part 201 and the second detection part 301 is reduced, and the first detection part 201 and the second detection part 301 clamp the arm 6, so that the blood pressure can be accurately measured. When the measurement is completed, the air bag 1 is deflated, the first clamping arm 2 is relatively rotated relative to the second clamping arm 3, the distance between the first detection part 201 and the second detection part 301 is increased, and the user can move the arm 6.

[0053] In an embodiment not shown in the figure, a fixed support can be provided, and the first clamping arm 2 is hinged with the fixed support, and the second clamping arm 3 is fixedly arranged on the fixed support. Since the second clamping arm 3 is fixed, the first clamping arm 2 is hinged with the fixed support, so that the first clamping arm 2 can be rotated relative to the second clamping arm 3. When the blood pressure needs to be measured, the arm 6 can be placed at the second detection part 301, and then the air bag 1 is inflated. After the air bag 1 is inflated, the air bag 1 is expanded, and the first clamping arm 2 is relatively rotated relative to the second clamping arm 3, the distance between the first detection part 201 and the second detection part 301 is reduced, and the first detection part 201 and the second detection part 301 clamp the arm 6, so that the blood pressure can be accurately measured. When the measurement is completed, the air bag 1 is deflated, the first clamping arm 2 is relatively rotated relative to the second clamping arm 3, the distance between the first detection part 201 and the second detection part 301 is increased, and the user can move the arm 6.

[0054] In one embodiment, the first end of the second clamping arm 3 is connected with the second end of the air bag 1.

[0055] In this embodiment, the first end of the first clamping arm 2 is connected with the first end of the air bag 1, the first end of the second clamping arm 3 is connected with the second end of the air bag 1, and the first clamping arm 2 is hinged with the second clamping arm 3, which is simple and compact in structure. When blood pressure needs to be measured, the arm 6 can be placed at the second detection part 301, and then the air bag 1 is inflated. After the air bag 1 is inflated, it expands, driving the first clamping arm 2 and the second clamping arm 3 to rotate relatively, the distance between the first detection part 201 and the second detection part 301 is reduced, and the first detection part 201 and the second detection part 301 clamp the arm 6, so that the blood pressure can be accurately measured. When the measurement is completed, the air bag 1 is deflated, the first clamping arm 2 and the second clamping arm 3 rotate relatively, the distance between the first detection part 201 and the second detection part 301 is increased, and the user can move the arm 6. The sleeve clamp structure, the user can inflate or deflate the air bag 1 with one hand, so that the sleeve clamp structure can clamp the arm 6 by himself, so that the blood pressure can be accurately measured.

[0056] In an embodiment not shown in the figure, the first end of the second clamping arm 3 is not connected with the air bag 1, but a fixed support is arranged, the second end of the air bag 1 is fixed on the fixed support, and the second clamping arm 3 is also fixed on the fixed support. The first clamping arm 2 is hinged with the second clamping arm 3, or the first clamping arm 2 is hinged with the fixed support. When blood pressure needs to be measured, the arm 6 can be placed at the second detection part 301, and then the air bag 1 is inflated. After the air bag 1 is inflated, it expands, driving the first clamping arm 2 to rotate relative to the second clamping arm 3, the distance between the first detection part 201 and the second detection part 301 is reduced, and the first detection part 201 and the second detection part 301 clamp the arm 6, so that the blood pressure can be accurately measured. When the measurement is completed, the air bag 1 is deflated, the first clamping arm 2 rotates relative to the second clamping arm 3, the distance between the first detection part 201 and the second detection part 301 is increased, and the user can move the arm 6.

[0057] In an embodiment, the second clamping arm 3 is symmetrically arranged with the first clamping arm 2. As shown in Figure 2 the first clamping arm 2 includes a first horizontal part 202, a first inclined part 203 and a second inclined part 204. The first horizontal part 202 is connected with the first end of the air bag 1; one end of the first inclined part 203 is connected with the first horizontal part 202, and the other end is provided with a first hinge part 205. The first inclined part 203 is inclined downward and inclined away from the air bag 1; one end of the second inclined part 204 is connected with the first hinge part 205, and the other end is connected with the first detection part 201. The second inclined part 204 is inclined upward and inclined away from the air bag 1.

[0058] As shown in Figure 3As shown, the second clamping arm 3 includes a second horizontal portion 302, a third inclined portion 303, and a fourth inclined portion 304. The second horizontal portion 302 is connected to the second end of the airbag 1; one end of the third inclined portion 303 is connected to the second horizontal portion 302, and the other end is provided with a second hinge portion 305. The first inclined portion 203 is inclined upward and tilted away from the airbag 1. The second hinge portion 305 is hinged to the first hinge portion 205 through a rotating shaft 4. One end of the fourth inclined portion 304 is connected to the second hinge portion 305, and the other end is connected to the second detection portion 301. The fourth inclined portion 304 is inclined downward and tilted away from the airbag 1.

[0059] In this embodiment, such as Figure 6 As shown, when blood pressure needs to be measured, the arm 6 can be placed at the second detection unit 301. Then, the airbag 1 is inflated. The inflated airbag 1 expands, causing the first horizontal part 202 of the first clamping arm 2 to move upwards, thus rotating the first horizontal part 202 clockwise upwards relative to the rotating shaft 4. The second inclined part 204 ensures that the plane of the first detection unit 201 is higher than the horizontal plane of the rotating shaft 4, so the first detection unit 201 rotates clockwise downwards relative to the rotating shaft 4. After the airbag 1 inflates, it causes the second horizontal part 302 of the second clamping arm 3 to move downwards, thus rotating the second horizontal part 302 counterclockwise downwards relative to the rotating shaft 4. The fourth inclined part 304 ensures that the plane of the second detection unit 301 is higher than the plane of the rotating shaft 4, so the second detection unit 301 rotates counterclockwise upwards relative to the rotating shaft 4. Therefore, the distance between the first detection unit 201 and the second detection unit 301 is reduced, and the first detection unit 201 and the second detection unit 301 clamp the arm 6, allowing for accurate blood pressure measurement.

[0060] Upon completion of the measurement, the airbag 1 deflates and contracts, causing the first horizontal section 202 of the first clamping arm 2 to move downwards. This causes the first horizontal section 202 to rotate counterclockwise downwards relative to the rotating shaft 4, and the first detection section 201 to rotate counterclockwise upwards relative to the rotating shaft 4. Simultaneously, the second horizontal section 302 of the second clamping arm 3 moves upwards, causing the second horizontal section 302 to rotate clockwise upwards relative to the rotating shaft 4, and the second detection section 301 to rotate clockwise downwards relative to the rotating shaft 4. Therefore, the distance between the first detection section 201 and the second detection section 301 increases, allowing the user to remove the arm 6.

[0061] In one embodiment, the airbag 1 has a connecting structure 102 at both ends, and the connecting structure 102 is fixedly connected to the first horizontal part 202 and the second horizontal part 302 respectively.

[0062] In this embodiment, the connection of the air bag 1 and the first clamping arm 2 and the second clamping arm 3 is facilitated by the connection structure 102 arranged at both ends of the air bag 1, which is fixedly connected with the first horizontal part 202 and the second horizontal part 302 respectively. When the air bag 1 inflates, the first clamping arm 2 and the second clamping arm 3 are not easily separated from the air bag 1. When blood pressure needs to be measured, the arm 6 can be placed at the second detection part 301, and then the air bag 1 is inflated. After the air bag 1 inflates, the connection structure 102 at the upper end of the air bag 1 moves with the inflation of the air bag 1, driving the first horizontal part 202 of the first clamping arm 2 to move upward, so that the first horizontal part 202 rotates clockwise upward relative to the pivot 4. The arrangement of the second inclined part 204 makes the plane where the first detection part 201 is located higher than the horizontal plane where the pivot 4 is located, so the first detection part 201 rotates counterclockwise downward relative to the pivot 4. The connection structure 102 at the lower end of the air bag 1 moves with the inflation of the air bag 1, driving the second horizontal part 302 of the second clamping arm 3 to move downward, so that the second horizontal part 302 rotates counterclockwise downward relative to the pivot 4. The arrangement of the fourth inclined part 304 makes the plane where the second detection part 301 is located higher than the plane where the pivot 4 is located, so the second detection part 301 rotates clockwise upward relative to the pivot 4. Therefore, the distance between the first detection part 201 and the second detection part 301 is reduced, and the first detection part 201 and the second detection part 301 clamp the arm 6, so that the blood pressure can be accurately measured.

[0063] When the measurement is completed, the air bag 1 deflates, and the air bag 1 contracts. The connection structure 102 at the upper end of the air bag 1 drives the first horizontal part 202 of the first clamping arm 2 to move downward, so that the first horizontal part 202 rotates counterclockwise downward relative to the pivot 4, and the first detection part 201 rotates counterclockwise upward relative to the pivot 4. The connection structure 102 at the lower end of the air bag 1 drives the second horizontal part 302 of the second clamping arm 3 to move upward, so that the second horizontal part 302 rotates clockwise upward relative to the pivot 4, and the second detection part 301 rotates clockwise downward relative to the pivot 4. Therefore, the distance between the first detection part 201 and the second detection part 301 is increased, and the user can move the arm 6 out.

[0064] In an alternative embodiment, the connection structure 102 is not arranged at both ends of the air bag 1, and the first horizontal part 202 and the second horizontal part 302 are glued to the end of the air bag 1.

[0065] In an embodiment, the connection structure 102 is connected with the first horizontal part 202 and the second horizontal part 302 by interference fit.

[0066] In this embodiment, the connecting structure 102 is connected with the first horizontal part 202 and the second horizontal part 302 in interference fit, which facilitates the connection of the air bag 1 with the first clamping arm 2 and the second clamping arm 3, and the air bag 1 is stably connected with the first clamping arm 2 and the second clamping arm 3 and is not easy to be separated, so as to ensure that the air bag 1 can drive the first clamping arm 2 and the second clamping arm 3 to move when the air bag 1 is inflated and deflated.

[0067] In one embodiment, the connecting structure 102 comprises a fixing groove 1021, and the first horizontal part 202 and the second horizontal part 302 are fixed in the fixing groove 1021 respectively.

[0068] In this embodiment, when being installed, the first horizontal part 202 is inserted into the fixing groove 1021 at the upper end of the air bag 1, and the second horizontal part 302 is inserted into the fixing groove 1021 at the lower end of the air bag 1, and the fixing groove 1021 is connected with the first horizontal part 202 and the second horizontal part 302 in interference fit, so as to ensure the stable connection of the air bag 1 with the first clamping arm 2 and the second clamping arm 3.

[0069] When the air bag 1 is inflated, the first clamping arm 2 and the second clamping arm 3 are not easy to be separated from the air bag 1. When the blood pressure needs to be measured, the arm 6 can be placed at the second detection part 301, and then the air bag 1 is inflated. After the air bag 1 is inflated, the fixing groove 1021 at the upper end of the air bag 1 moves with the inflation of the air bag 1, drives the first horizontal part 202 of the first clamping arm 2 to move upward, so that the first horizontal part 202 rotates clockwise upward relative to the rotating shaft 4, and the setting of the second inclined part 204 makes the plane where the first detection part 201 is located higher than the horizontal plane where the rotating shaft 4 is located, so that the first detection part 201 rotates counterclockwise downward relative to the rotating shaft 4; the fixing groove 1021 at the lower end of the air bag 1 moves with the inflation of the air bag 1, drives the second horizontal part 302 of the second clamping arm 3 to move downward, so that the second horizontal part 302 rotates counterclockwise downward relative to the rotating shaft 4, and the setting of the fourth inclined part 304 makes the plane where the second detection part 301 is located higher than the plane where the rotating shaft 4 is located, so that the second detection part 301 rotates clockwise upward relative to the rotating shaft 4. Therefore, the distance between the first detection part 201 and the second detection part 301 is reduced, and the first detection part 201 and the second detection part 301 clamp the arm 6, so as to accurately measure the blood pressure.

[0070] When the measurement is completed, the air bag 1 is deflated, the air bag 1 is contracted, the fixed groove 1021 at the upper end of the air bag 1 drives the first horizontal part 202 of the first clamping arm 2 to move downward, so that the first horizontal part 202 rotates counterclockwise downward relative to the rotating shaft 4, and the first detection part 201 rotates counterclockwise upward relative to the rotating shaft 4; the fixed groove 1021 at the lower end of the air bag 1 drives the second horizontal part 302 of the second clamping arm 3 to move upward, so that the second horizontal part 302 rotates clockwise upward relative to the rotating shaft 4, and the second detection part 301 rotates clockwise downward relative to the rotating shaft 4. Therefore, the distance between the first detection part 201 and the second detection part 301 is increased, and the user can move the arm 6 out.

[0071] In an embodiment not shown in the figure, the connecting structure 102 can be a connecting buckle, which is clamped with the first horizontal part 202 of the first clamping arm 2 and the second horizontal part 302 of the second clamping arm 3.

[0072] In another embodiment not shown in the figure, the connecting structure 102 can be a plurality of protruding columns, the protruding columns at the top end of the air bag 1, i.e. the first end, extend upward, the first horizontal part 202 of the first clamping arm 2 is provided with connecting holes suitable for the insertion of the protruding columns, and the protruding columns are inserted into the connecting holes and are in interference fit with the connecting holes. The protruding columns at the bottom end of the air bag 1, i.e. the second end, extend downward, the second horizontal part 302 of the second clamping arm 3 is provided with connecting holes suitable for the insertion of the protruding columns, and the protruding columns are inserted into the connecting holes and are in interference fit with the connecting holes.

[0073] Specifically, in an embodiment, as shown in Figure 4 and Figure 5 the connecting structure 102 includes two L-shaped plate members arranged opposite to each other and spaced apart, each L-shaped plate member includes a vertical plate connected with the air bag 1 and a horizontal plate connected with the top end of the vertical plate, the horizontal plates of the two L-shaped plate members at the same end of the air bag 1 are close to each other and have a certain gap, and the fixed groove 1021 is formed between the two L-shaped plate members.

[0074] In this embodiment, since the horizontal plates of the two L-shaped plate members at the same end of the air bag 1 are close to each other and have a certain gap, the L-shaped plate members have a certain elasticity, which facilitates the insertion of the first horizontal part 202 of the first clamping arm 2 and the second horizontal part 302 of the second clamping arm 3 into the fixed groove 1021, and can firmly fix the first horizontal part 202 and the second horizontal part 302.

[0075] In an embodiment, the vertical plate is integrally formed with the air bag 1.

[0076] In this embodiment, since the vertical plate is integrally formed with the air bag 1, the structure is simple and stable and reliable.

[0077] In an alternative embodiment, the vertical plate and the air bag 1 are connected together by adhesion.

[0078] In one embodiment, the air bag 1 is a blow molding piece, and the connecting structure 102 is integrally formed with the air bag 1.

[0079] In one embodiment not shown in the figure, the connecting structure 102 at the top end of the air bag 1, i.e. the first end, can be a reverse U-shaped structure, which forms a fixed slot 1021 with the top end of the air bag 1, and the first horizontal part 202 of the first clamping arm 2 is inserted into the fixed slot 1021. The connecting structure 102 at the bottom end of the air bag 1, i.e. the second end, can be a U-shaped structure, which forms a fixed slot 1021 with the bottom end of the air bag 1, and the second horizontal part 302 of the second clamping arm 3 is inserted into the fixed slot 1021.

[0080] In one embodiment, the first detection part 201 and / or the second detection part 301 is / are horizontally arranged.

[0081] In this embodiment, by horizontally arranging the first detection part 201 and / or the second detection part 301, when the user needs to measure the blood pressure, the user only needs to place the arm 6 on the second detection part 301. When the air bag 1 is inflated and expands, the first clamping arm 2 and the second clamping arm 3 are driven to rotate relatively, the distance between the first detection part 201 and the second detection part 301 is reduced, and the first detection part 201 and the second detection part 301 clamp the arm 6, so that the blood pressure can be accurately measured. When the measurement is completed, the air bag 1 is deflated, the first clamping arm 2 and the second clamping arm 3 rotate relatively, the distance between the first detection part 201 and the second detection part 301 is increased, and the user can remove the arm 6.

[0082] Specifically, in one embodiment, as shown in Figure 1 the first detection part 201 and the second detection part 301 are both horizontally arranged. In one embodiment not shown in the figure, the second detection part 301 can be horizontally arranged, and the first detection part 201 can have a certain arc. In another embodiment not shown in the figure, the second detection part 301 can have a certain arc, and the first detection part 201 can be horizontally arranged.

[0083] In one embodiment, the air inlet 101 is arranged at the middle part of the air bag 1.

[0084] In this embodiment, the air inlet 101 is arranged at the middle of the air bag 1, so that the air bag 1 can uniformly expand to both ends when inflated. In particular, when the first end of the first clamping arm 2 is connected to the first end of the air bag 1, the first end of the second clamping arm 3 is connected to the second end of the air bag 1, and the first clamping arm 2 is hinged to the second clamping arm 3, the first clamping arm 2 and the second clamping arm 3 rotate simultaneously when the air bag 1 is inflated, the distance between the first detection part 201 and the second detection part 301 is reduced, the first detection part 201 and the second detection part 301 clamp the arm 6, and the blood pressure can be accurately measured. When the measurement is completed, the air bag 1 is deflated, the first clamping arm 2 and the second clamping arm 3 rotate simultaneously, the distance between the first detection part 201 and the second detection part 301 is increased, and the user can move the arm 6.

[0085] In an embodiment not shown in the drawings, when the first end of the second clamping arm 3 is not connected to the air bag 1, but a fixed support is arranged, the second end of the air bag 1 is fixed to the fixed support, the second clamping arm 3 is also fixed to the fixed support, and the first clamping arm 2 is hinged to the second clamping arm 3 or the first clamping arm 2 is hinged to the fixed support, the air inlet 101 can be arranged at the bottom of the air bag 1.

[0086] In an embodiment, the air bag 1 is provided with multiple layers of arc-shaped pleats.

[0087] In this embodiment, the arrangement of the arc-shaped pleats can increase the service life of the air bag 1 and achieve directional expansion of the air bag 1 after inflation.

[0088] According to the embodiment of the present application, in another aspect, a sphygmomanometer is also provided, which comprises the sleeve clamp structure of the sphygmomanometer.

[0090] When the blood pressure needs to be measured, the arm 6 can be placed at the second detection part 301, and then the host is operated to inflate the air bag 1 by the air pump. After the air bag 1 is inflated, it expands to drive the first clamping arm 2 and the second clamping arm 3 to rotate relatively, the distance between the first detection part 201 and the second detection part 301 is reduced, the first detection part 201 and the second detection part 301 clamp the arm 6, and the blood pressure can be accurately measured. When the measurement is completed, the air bag 1 is deflated, the first clamping arm 2 and the second clamping arm 3 rotate relatively, the distance between the first detection part 201 and the second detection part 301 is increased, and the user can move the arm 6. The sleeve clamp structure can be inflated or deflated by the user with one hand, so that the sleeve clamp structure can clamp the arm 6 by itself, thereby accurately measuring the blood pressure.

[0091] While embodiments of the application have been described in connection with the preferred embodiments of the various figures, those of ordinary skill in the art will appreciate that various modifications and changes can be made without departing from the spirit and scope of the application, and that such modifications and changes fall within the scope of the appended claims.
