Description

Technical Field

[0001] The present application belongs to the technical field of medical devices, and specifically relates to a blood pressure monitor cuff and a blood pressure monitor. Background Art

[0002] The cuff is an important component of the sphygmomanometer. It is usually put on the arm of the subject when measuring blood pressure. When working, the cuff tightly wraps the subject's arm under the action of the air bag in the cuff, and then fills the inside with a certain amount of gas and continues to pressurize it through a manual or mechanical pump. When the pressure in the air bag reaches the subject's systolic pressure, the blood no longer flows in the blood vessels, and then the pressure in the air bag is slowly reduced. When the pressure is reduced to the subject's diastolic pressure, the blood begins to flow again from the artery. The recovery of this blood flow can be detected by a stethoscope or electronic sensor, thereby determining the subject's systolic and diastolic pressures.

[0003] Currently, when wearing the cuff, one end of the cuff needs to be placed tightly against the arm of the subject, and then the other end of the cuff is wrapped around the arm of the subject, and the two ends of the cuff are bonded together by Velcro. However, since this method is difficult to operate with one hand, other personnel are required to assist the subject, which increases the difficulty for the subject to use it alone.

[0004] In order to reduce the difficulty for the subject to use the cuff alone, some cuffs have added a reeling device, which uses the reeling rope of the reeling device to apply tension to the end of the cuff, so that the cuff can tightly wrap the subject's arm. Although this eliminates the step of the subject wrapping the cuff around his or her arm, which reduces the difficulty of wearing the cuff to a certain extent, the cuff is relatively soft and is in a collapsed state before being worn on the subject's arm. As a result, when the subject wears the cuff, it is necessary to first open the cuff and then extend the arm into the cuff, which also has the defect of being difficult for the subject to wear the cuff alone. At the same time, when the cuff is rolled up, the friction between the contact parts of the cuff is large, which affects the smoothness of rolling up the cuff and causes the reeling rope to break easily due to the large tension, thereby affecting the service life of the cuff. Summary of the invention

[0005] The present application provides a cuff for a blood pressure monitor, so as to reduce the difficulty of a subject wearing the cuff, improve the smoothness of rolling up the cuff, and increase the service life of the cuff.

[0006] The technical solution adopted in this application is:

[0007] A blood pressure monitor cuff, comprising:

[0008] A cuff body, wherein the cuff body has a length direction and a width direction perpendicular to the length direction, the length direction extends along the winding direction of the cuff body, the cuff body has a first end and a second end opposite to the first end in its own length direction, the first end has an opening, the width of the first end is greater than the width of the second end, so that the second end can extend into the interior of the cuff body through the opening, the cuff body comprises an air bag, a bracket and a cover body arranged outside the air bag and the bracket, the bracket is arranged in a cylindrical or winding shape, the cover body comprises an inner peripheral layer in contact with a measured part and an outer peripheral layer opposite to the inner peripheral layer, the air bag is located between the inner peripheral layer and the bracket, the bracket has a head end and a tail end opposite to the head end, the head end is fixedly connected to the first end, and the tail end is fixedly connected to the second end;

[0009] The reeling mechanism is arranged on the cuff body and is used to drive the second end to move in the reeling direction of the cuff body so that the length of the second end extending into the cuff body changes.

[0010] By adopting the above-mentioned technical scheme, when the subject wears the cuff in the present application, the cuff is first put on the subject's arm, and then the reeling mechanism is operated, and then the reeling mechanism drives the second end to make the second end move toward the inside of the cuff body through the opening, and then the length of the second end extending into the cuff body changes, thereby changing the diameter of the cuff body, and finally making the cuff body tightly wrap around the subject's arm to complete the wearing of the cuff body on the subject's arm.

[0011] Since the cuff body has a cylindrical or coiled bracket, and the head end and the tail end of the bracket are respectively fixedly connected to the first end and the second end, the bracket can support the cuff body to keep the cuff body in a cylindrical shape, so as to facilitate the subject to wear the cuff on the arm alone, thereby reducing the difficulty for the subject to wear the cuff alone, and further improving the subject's user experience.

[0012] In addition, since the air bag is located between the inner circumferential layer and the bracket, when the cuff body is rolled up, the inner circumferential layer at the second end contacts the bracket at the first end to reduce the friction between the cuff bodies when the cuff body is rolled up, thereby reducing the resistance when the cuff body is rolled up, so as to improve the smoothness when the cuff body is rolled up, and can also reduce the tension on the rolling mechanism, so as to avoid the phenomenon that the rolling mechanism is easily damaged, so as to achieve the effect of extending the service life of the cuff, thereby improving the durability of the cuff.

[0013] Furthermore, when the cuff tightly wraps around the arm of the subject, the bracket is deformed, and when the cuff is removed from the arm of the subject, the elastic force of the bracket can be first used to gradually increase the diameter of the cuff body, so that a partial area of ​​the cuff body is gradually separated from the arm of the subject, thereby forming an accommodating space between the cuff body and the arm of the subject, so as to prevent the subject from extending his other hand into the accommodating space to apply a pulling force to the cuff body, thereby achieving the effect of facilitating the removal of the cuff from the arm of the subject.

[0014] Optionally, the winding mechanism includes a winding structure and a winding rope, the winding structure including a base arranged in the middle part of the length direction of the cuff body, a winding disk arranged inside the base, a rotary cover arranged on the outside of the base, and a stopper arranged on the top of the base and located inside the rotary cover, the winding rope has a connecting section connected to the second end and a winding section passing through the base and connected to the winding disk, the rotary cover can move along the axial direction of the base so that the rotary cover has a linkage position and a disconnection position, in the linkage position, the rotary cover and the winding disk are linked to each other so that the winding disk can rotate along the first direction with the rotary cover, and the winding rope is wound around the winding disk, the stopper and the rotary cover stopper cooperate with each other in the second direction to limit the rotation of the rotary cover in the second direction, the second direction and the first direction are opposite to each other, in the disconnection position, the rotary cover releases the linkage cooperation with the winding disk, and the stopper releases the stop cooperation with the rotary cover.

[0015] By adopting the above technical solution, after the cuff is worn on the arm of the subject, the subject needs to first press the rotary cap, thereby moving the rotary cap from the disconnected position to the linked position, and then twisting the rotary cap along the first direction to make the rotary cap drive the winding disk to rotate, so that the winding disk applies tension to the winding rope, and the winding rope is wound around the winding disk, and at the same time the winding rope applies tension to the second end, so that the second end extends into the interior of the cuff body through the opening under the action of the winding rope, and the bracket is deformed, and finally the cuff body tightly wraps the arm of the subject.

[0016] Because when the rotary cover is in the linkage position, the stopper cooperates with the rotary cover to stop in the second direction, thereby limiting the rotation of the rotary cover along the second direction, so as to achieve locking of the rotation of the rotary cover along the second direction, so as to avoid the second end moving toward the outside of the cuff body under the action of the arm of the subject and the bracket, thereby increasing the stability of the cuff body after it is tightly wrapped around the arm of the subject.

[0017] When the cuff is removed from the arm of the subject, the rotary cover is first pulled, and then the rotary cover moves from the linkage position to the disconnection position. At this time, the rotary cover releases the linkage cooperation with the reel, and the stopper releases the stop cooperation with the rotary cover. Then the bracket restores its deformation to gradually increase the diameter of the cuff body, and the cuff body gradually separates from the arm of the subject. Then, a pulling force is applied to the cuff body in a direction away from the arm of the subject to continue to increase the diameter of the cuff body. Finally, the cuff body is separated from the arm of the subject.

[0018] Furthermore, because the rotary cap releases the linkage with the take-up reel in the disconnected position, the rotary cap cannot rotate along with the take-up reel when the cuff body recovers its deformation in the direction of increasing its diameter, thereby reducing the force required for the cuff body to recover its deformation in the direction of increasing its diameter, thereby reducing the difficulty for the subject to remove the cuff body from the arm, thereby further improving the user experience of the subject.

[0019] Optionally, the anti-rotation member includes a ring body that is snap-fitted with the base and an elastic arm arranged on the outer periphery of the ring body, the elastic arm having a fixed end connected to the ring body and a swinging end opposite to the fixed end, the swinging end can swing elastically around the fixed end, and a stop tooth is provided on the outer side of the swinging end, and a locking tooth is provided on the inside of the rotary cover, and when the rotary cover is in the linkage position, the stop tooth can move relative to the locking tooth in the first direction and stop and cooperate with the locking tooth in the second direction.

[0020] By adopting the above technical scheme, when the cuff body is rolled up so that the cuff body tightly wraps the arm of the subject, the rotary cover is first pressed, and then the rotary cover moves from the disconnected position to the linked position, and then the rotary cover is twisted along the first direction, and the rotary cover drives the locking tooth to move. At this time, the swinging end of the elastic arm swings around the fixed end under the action of the locking tooth, so that the stop tooth and the locking tooth form a avoidance, thereby ensuring that the rotary cover can rotate along the first direction, and finally the second end gradually extends into the interior of the cuff body through the opening, and when the locking tooth and the stop tooth rotate relative to each other, the swinging end elastically swings around the fixed end, so that the stop tooth and the locking tooth continue to collide and make a clicking sound, so as to remind the subject that the stopper has worked at this time, thereby avoiding the phenomenon that the subject finds that the stopper is not working after the cuff body is tightly wrapped around the subject's arm, that is, avoiding the phenomenon that the subject needs to twist the rotary cover again, thereby further improving the subject's wearing efficiency of the cuff.

[0021] Optionally, the top of the base has a through hole, the hole wall of the through hole is provided with a clamping portion, and the bottom of the ring body is provided with a matching portion that is clamped and matched with the clamping portion.

[0022] By adopting the above technical solution, when assembling the stopper, the mating portion and the snap-on portion are first aligned, and then pressure is applied to the stopper in the direction of the base so that the mating portion and the snap-on portion are snap-fitted together to complete the assembly of the stopper. In this process, it is only necessary to press the stopper, thereby reducing the difficulty of assembling the stopper and ensuring the connection stability between the stopper and the base. Moreover, compared with setting the stopper and the base as an integrated structure, the production difficulty of the base is reduced, the yield rate of the base is improved, and the production cost of the base is greatly reduced.

[0023] Optionally, a hole wall of the through hole is provided with an avoidance groove, the clamping portion is provided on the groove wall of the avoidance groove, and at least a part of the matching portion is located in the avoidance groove.

[0024] By adopting the above technical scheme, since the clamping part is arranged on the groove wall of the avoidance groove, and at least a part of the matching part is located in the avoidance groove, after the matching part and the clamping part are clamped together, the groove wall of the avoidance groove can cooperate with the stopper of the matching part to avoid the phenomenon that the anti-rotation part may rotate relative to the base, thereby ensuring the limiting effect of the anti-rotation part on the rotation of the rotary cover in the second direction, so as to ensure the stability of the cuff after tightly wrapping the arm of the subject, and further ensure the accuracy of blood pressure measurement; and it can also simplify the structural design of the clamping part and the matching part, so as to further reduce the production difficulty of the anti-rotation part and the base, improve the production efficiency of the anti-rotation part and the base, and reduce the production cost.

[0025] Optionally, the rotary cover is clamped with an active disk that can extend into the interior of the ring body, the side of the active disk is provided with active teeth, the top of the base is provided with a through hole, the top of the winding disk is provided with a driven tooth that extends into the through hole, and when the rotary cover is in the linkage position, the active tooth engages with the driven tooth.

[0026] By adopting the above technical solution, when the cuff body is rolled up, the rotary cover is first pressed to move the rotary cover from the disconnected position to the linked position, at which time the active gear and the driven gear are meshed together, and then the rotary cover is twisted along the first direction, the rotary cover drives the active disk to rotate, so that the active disk drives the winding disk to rotate under the action of the active gear and the driven gear, and the winding disk winds up the winding rope, so that the winding rope applies tension to the second end, and the second end gradually enters the interior of the cuff body through the opening to achieve the winding of the cuff body.

[0027] Since the active disk is clamped on the screw cap, the production difficulty of the screw cap is reduced, the yield rate of the screw cap is improved, and the production cost of the screw cap is reduced.

[0028] Optionally, the active disk has a center hole, the hole wall of the center hole is provided with a convex rib, the top of the winding disk is provided with a limiting arm extending into the center hole, the outer side of the limiting arm is provided with a limiting protrusion, when the rotary cover is in the linkage position, the limiting protrusion is located above the convex rib, and when the rotary cover is in the disconnection position, the limiting protrusion is located below the convex rib.

[0029] By adopting the above technical solution, since the active disk has a center hole, a limiting arm extending into the center hole is provided on the top of the winding disk, and then the cooperation between the limiting arm and the center hole can realize the mutual positioning of the active disk and the winding disk, so as to ensure that when the rotary cover is in the linkage position, the active teeth can engage with the driven teeth, thereby ensuring the winding efficiency of the cuff body.

[0030] Furthermore, since the hole wall of the center hole is provided with a convex rib and a limiting protrusion is provided on the outer side of the limit arm, when the rotary cover is in the linkage position, the limiting protrusion is located above the convex rib, and when the rotary cover is in the disconnected position, the limiting protrusion is located below the convex rib. As a result, when the rotary cover moves from the disconnected position to the linkage position, the limiting arm can collide with the convex rib to make a sound to alert the user that the rotary cover has moved to the linkage position. Similarly, when the rotary cover moves from the linkage position to the disconnected position, the limiting arm will also collide with the convex rib to make a sound to alert the user that the rotary cover has moved to the disconnected position, so as to avoid the phenomenon that the rotary cover is separated from the base due to excessive operation of the rotary cover by the user, thereby further improving the user experience of the testee.

[0031] Optionally, at least two limiting arms are provided along the circumference of the center hole, guide surfaces are provided on both the top and bottom sides of the rib, and matching surfaces that can cooperate with the guide surfaces are provided on both the top and bottom sides of the limiting protrusion.

[0032] By adopting the above technical scheme, since at least two limiting arms are arranged along the circumference of the center hole, the positioning effect of the limiting arm and the convex rib on the active disk and the winding disk is increased; and, guide surfaces are arranged on both sides of the top and bottom wall of the convex rib, and matching surfaces that can cooperate with the guide surfaces are arranged on both sides of the top and bottom of the limiting protrusion, thereby reducing the force required to pull or press the rotary cover, so as to achieve the effect of facilitating the operation of the rotary cover by the person being measured, thereby further improving the user experience of the person being measured; at the same time, the existence of the guide surface and the matching surface avoids the phenomenon that the clamping force between the limiting protrusion and the convex rib is too large to affect the stability of the connection between the active disk and the rotary cover, thereby ensuring the stability of the connection between the active disk and the rotary cover.

[0033] Optionally, the rotary cover is provided with a clamping portion capable of extending into the interior of the ring body, and the outer periphery of the active disk is provided with a fixing portion that is clamped and matched with the clamping portion.

[0035] Optionally, the thickness of the anti-rotation member, the thickness of the locking tooth, the height of the driving tooth, and the height of the driven tooth are all smaller than the distance between the linkage position and the disconnection position.

[0036] By adopting the above technical solution, since the thickness of the stopper, the thickness of the locking tooth, the height of the driving tooth and the height of the driven tooth are all smaller than the distance between the linkage position and the disconnection position, after the rotary cover moves from the linkage position to the disconnection position, the stopper can be separated from the locking tooth, and the driving tooth can be separated from the driven tooth, so as to ensure that when the rotary cover is in the disconnection position, the winding reel can rotate in the second direction to facilitate the subject to remove the cuff from the arm.

[0037] Optionally, the base includes a seat body and a shell that is clamped inside the seat body, and the seat body and the shell together form a receiving cavity for receiving the winding reel.

[0038] By adopting the above technical solution, when assembling the winding reel, the winding reel is first placed inside the shell, and then the base is installed so that the shell and the seat body are snap-fitted together, thereby achieving the shell being able to block the winding reel while reducing the difficulty of assembling the winding reel, thereby improving the assembly efficiency of the winding reel, and then improving the production efficiency of the winding mechanism.

[0039] Optionally, the shell is provided with a threading hole for the winding rope to pass through, the outside of the shell is provided with a guide rib corresponding to the threading hole, and the seat body is provided with a limiting notch for accommodating the guide rib.

[0041] Optionally, a decorative ring is sleeved on the outside of the seat body, the guide ribs extend to the outside of the seat body, and the decorative ring is located at the bottom of the guide ribs, so that the guide ribs can apply an extrusion force on the decorative ring away from the direction of the screw cap.

[0047] Optionally, the winding drum is provided with at least two rows of fixing holes, and the winding rope is passed through one row of the fixing holes and then folded back and passed through another row of the fixing holes.

[0048] By adopting the above technical solution, since the winding drum is provided with at least two rows of fixing holes, the winding rope is passed through one row of fixing holes and then folded back and passed through the other row of fixing holes, thereby increasing the connection stability between the winding rope and the winding drum, avoiding the possibility of the winding rope being detached from the winding drum, thereby ensuring the service life of the cuff.

Moreover, the specific features, structures, materials or characteristics described may be combined in an appropriate manner in any one or more embodiments or examples.

[0081] Reference Figures 1 to 15 , discloses a cuff for a blood pressure monitor, comprising a cuff body 1 and a winding mechanism 2, wherein the cuff body 1 has a length direction and a width direction perpendicular to the length direction, the length direction extends along the winding direction of the cuff body 1, the cuff body 1 has a first end and a second end opposite to the first end in its own length direction, the first end has an opening 14, the width of the first end is greater than the width of the second end, so that the second end can extend into the interior of the cuff body 1 through the opening 14.

[0082] The cuff body 1 includes an air bag 11, a bracket 12, and a cover body 13 arranged outside the air bag 11 and the bracket 12. The bracket 12 is arranged in a cylindrical or coiled shape. The cover body 13 includes an inner peripheral layer 131 in contact with the measured part and an outer peripheral layer 132 opposite to the inner peripheral layer 131. The air bag 11 is located between the inner peripheral layer 131 and the bracket 12. The bracket 12 has a head end and a tail end opposite to the head end. The head end is fixedly connected to the first end, and the tail end is fixedly connected to the second end.

[0083] The reeling mechanism 2 is disposed on the cuff body 1 and is used to drive the second end to move in the reeling direction of the cuff body 1 so that the length of the second end extending into the cuff body 1 changes.

[0084] It can be understood that the air bag 11 mentioned in the present application can be an airbag in the prior art, or other structures that can be filled with a certain amount of gas by manual or mechanical pumps. The bracket 12 is made of a material that is elastic and has a certain hardness, such as PP material, etc., and the above-mentioned "the bracket 12 is arranged in a cylindrical or coiled shape" does not simply mean that the bracket 12 is in a cylindrical or coiled shape. It can be that the bracket 12 is in a cylindrical or coiled shape under the constraint of the winding mechanism 2, and it can also be that the shape of the bracket 12 itself is cylindrical or coiled.

[0085] When the subject wears the cuff in the present application, the cuff is first put on the subject's arm, and then the reeling mechanism 2 is operated, and then the reeling mechanism 2 drives the second end so that the second end moves toward the inside of the cuff body 1 through the opening 14, and then the length of the second end extending into the cuff body 1 changes, thereby changing the diameter of the cuff body 1, and finally making the cuff body 1 tightly wrap around the subject's arm to complete the wearing of the cuff body 1 on the subject's arm.

[0086] Since the cuff body 1 has a cylindrical or coiled bracket 12, and the head end and the tail end of the bracket 12 are respectively fixedly connected to the first end and the second end, the bracket 12 can support the cuff body 1 to keep the cuff body 1 in a cylindrical shape, so as to facilitate the subject to wear the cuff on the arm alone, thereby reducing the difficulty of the subject to wear the cuff alone, and further improving the subject's user experience.

[0087] In addition, since the air bag 11 is located between the inner circumferential layer 131 and the bracket 12, on the one hand, when the cuff body 1 is rolled up, the inner circumferential layer 131 at the second end contacts the bracket 12 at the first end, so as to reduce the friction between the second end and the cuff body 1 when the cuff body 1 is rolled up, thereby reducing the resistance when the cuff body 1 is rolled up, so as to improve the smoothness when the cuff body 1 is rolled up, and it can also reduce the tension on the rolling mechanism 2, so as to avoid the phenomenon that the rolling mechanism 2 is easily damaged, so as to achieve the effect of extending the service life of the cuff, thereby improving the durability of the cuff; on the other hand, compared with the solution in which the air bag 11 is located between the bracket 12 and the outer circumferential layer 132, the air bag 11 directly applies pressure to the arm of the subject through the inner circumferential layer 131, thereby avoiding the phenomenon that the measurement accuracy is affected by the relatively large hardness of the bracket 12, thereby improving the measurement accuracy of the blood pressure monitor equipped with the cuff in the present application.

[0088] Furthermore, when the cuff tightly wraps around the arm of the subject, the bracket 12 is deformed, and when the cuff is removed from the arm of the subject, the elastic force of the bracket 12 can be first used to gradually increase the diameter of the cuff body 1, so that a partial area of ​​the cuff body 1 is gradually separated from the arm of the subject, thereby forming an accommodating space between the cuff body 1 and the arm of the subject, so as to prevent the subject from extending his other hand into the accommodating space to apply a pulling force to the cuff body 1, so as to facilitate the removal of the cuff from the arm of the subject.

[0089] In a preferred embodiment, a low-resistance layer is provided on the inner side of the outer layer 132, so that the two sides of the second end extending into the cuff body 1 through the opening 14 contact the bracket 12 and the low-resistance layer respectively, so as to further reduce the resistance when the cuff body 1 is rolled up, thereby further reducing the force required when rolling up the cuff body 1 and further extending the service life of the rolling mechanism 2.

[0090] It should be noted that the low-resistance layer may be formed by a low-resistance material coated on the inner side of the outer peripheral layer 132 , or may be formed by a low-resistance fabric pasted on the inner side of the outer peripheral layer 132 .

[0091] The present application does not specifically limit the formation method of the width of the first end being greater than the width of the second end. Preferably, refer to Figure 1 and Figure 2 , the width of the cuff body 1 is gradually reduced from the first end to the second end, that is, the planar shape of the cuff body 1 after unfolding is an isosceles trapezoid, so as to improve the appearance quality of the cuff body 1 and reduce the difficulty of producing the cuff body 1. In other embodiments, the cuff body 1 may include a first section and a second section, the width of the first section is greater than the width of the second section, and the end of the first section away from the second section forms the first end, and the end of the second section away from the first section forms the second end, so that the width of the first end is greater than the width of the second end.

[0092] The present application does not specifically limit the formation method of the opening 14. Preferably, the first end of the inner peripheral layer 131 is fixedly connected to the head end of the bracket 12 and has no direct connection with the first end of the outer peripheral layer 132, so that the opening 14 is formed between the first end of the outer peripheral layer 132 and the head end of the bracket 12. In other embodiments, the opening 14 can also be formed by a strip-shaped notch provided at the first end of the outer peripheral layer 132.

[0093] In a preferred embodiment, the shape of the bracket 12 is adapted to the shape of the cover 13, that is, the shape of the cuff body 1 is determined by the cover 13, and the shape of the bracket 13 is set to be adapted to the cover 13 so that the bracket 12 can fully support the cover 13, so that the shape of the cuff is more regular, which further reduces the difficulty of the subject wearing the cuff on the one hand, and improves the appearance quality of the cuff on the other hand. Of course, in other embodiments, the width of the bracket 12 can also be set to be equal to the width of the second end to reduce the production cost of the bracket 12.

[0094] In a preferred embodiment, an open retaining frame is provided at the first end of the outer layer 132, and the open retaining frame is protruded in a direction away from the inner layer 131, so that the first end of the outer layer 132 remains separated from the bracket 12, so as to further reduce the resistance when the second end moves toward the inside of the cuff body 1, so as to further increase the smoothness when the cuff is rolled up.

[0095] The present application does not specifically limit the structure of the open holder. Preferably, the open holder is a rod-shaped structure, and both ends of the open holder are bent toward the side where the inner peripheral layer 131 is located, so that the first end of the outer peripheral layer 132 is kept separated from the bracket 12 under the action of the open holder. In other embodiments, the open holder can also be a C-shaped sheet structure or other structures that can support the first end of the outer peripheral layer 132.

[0096] In a preferred embodiment, one end of the air bag 11 is located at the first end, and the second end can extend into the cuff body 1 by a length L1, the length of the air bag 11 is L2, and the length of the cuff body 1 is L, wherein L, L1 and L2 satisfy: L2=L-L1.

[0097] It should be noted that one end of the air bag 11 is located at the first end, which means that one end of the air bag 11 is flush with the first end of the cuff body 1 or is in contact with the inner side of the cover 13 located at the first end, and the length L1 that the second end can extend into the cuff body 1 refers to the maximum length that the second end can extend into the cuff body 1, that is, in this state, the second end cannot continue to extend into the interior of the cuff body 1.

[0098] Since the length of the air bag 11 is equal to the length of the cuff body 1 minus the maximum length that the second end can extend into the cuff body 1, the phenomenon of the air bag 11 being rolled up into the cuff body 1 through the opening 14 is avoided, thereby avoiding affecting the blood pressure measurement and signal collection of the subject, thereby ensuring the accuracy of blood pressure measurement.

[0099] In a preferred embodiment, referring to Figure 1 and Figure 1 The air bag 11 has an air nozzle 111, and the bracket 12 and the outer layer 132 are provided with a positioning hole 121 through which the air nozzle 111 extends. The peripheral side of the air nozzle 111 contacts the hole wall of the positioning hole 121 to position the air bag 11, and then the air bag 11 can be positioned by utilizing the cooperation between the air nozzle 111 and the positioning hole 121 to increase the stability of the air bag 11; at the same time, compared with the hot pressing of the edge of the air bag 11 and the cover body 13 in the prior art, the hot pressing step is omitted, the production difficulty and production cost of the cuff are reduced, and the production efficiency of the cuff is greatly improved.

[0100] Further, see Figure 1 and Figure 2The reeling mechanism 2 is located in the middle of the length direction of the cuff body 1 to ensure that the second end can be inserted into the cuff body 1 to increase the application range of the cuff body 1, and at the same time reduce the length of the reeling rope 22 in the reeling mechanism 2 to avoid the phenomenon that the reeling rope 22 is easily broken due to stress concentration, thereby achieving the effect of extending the service life of the cuff; and the air nozzle 111 is located at the side or end of the reeling mechanism 2, on the one hand, avoiding the phenomenon that the existence of the air nozzle 111 affects the length of the second end that can be inserted into the cuff body 1, and on the other hand, the air nozzle 111 and the reeling mechanism 2 are concentrated in the middle of the cuff body 1, so that the cuff is more regular and the appearance quality of the cuff is improved.

[0101] The present application does not specifically limit the structure of the winding mechanism 2. Preferably, refer to Figures 1 to 15 The winding mechanism 2 includes a winding structure 21 and a winding rope 22. The winding structure 21 includes a base 211 disposed in the middle of the length direction of the cuff body 1, a winding disk 212 disposed inside the base 211, a rotary cover 213 sleeved outside the base 211, and a rotation stopper 214 disposed on the top of the base 211 and located inside the rotary cover 213. The winding rope 22 has a connecting section connected to the second end and a winding section passing through the base 211 and connected to the winding disk 212. The rotary cover 213 can move along the axial direction of the base 211 so that the rotary cover 21 3 has a linkage position and a disconnection position; when in the linkage position, the rotary cover 213 is linked with the winding disk 212 so that the winding disk 212 can rotate along the first direction following the rotary cover 213, and the winding rope 22 is wound around the winding disk 212, and the stopper 214 is stopped in the second direction with the rotary cover 213 to limit the rotation of the rotary cover 213 in the second direction, and the second direction is opposite to the first direction; when in the disconnection position, the rotary cover 213 is released from the linkage with the winding disk 212, and the stopper 214 is released from the stopper with the rotary cover 213.

[0102] Specifically, refer to Figure 2 The base 211 is fixedly connected to the bracket 12 and extends out of the outer peripheral layer 132 to increase the stability of the winding mechanism 2 .

[0103] After the cuff is worn on the arm of the subject, the subject needs to first press the rotary cover 213, thereby moving the rotary cover 213 from the disconnected position to the linked position, and then twisting the rotary cover 213 along the first direction to make the rotary cover 213 drive the winding disk 212 to rotate, so that the winding disk 212 applies a pulling force to the winding rope 22, and the winding rope 22 is wound around the winding disk 212. At the same time, the winding rope 22 applies a pulling force to the second end, so that the second end extends into the interior of the cuff body 1 through the opening 14 under the action of the winding rope 22, and the bracket 12 is deformed, and finally the cuff body 1 tightly wraps the arm of the subject.

[0104] When the rotary cover 213 is in the linkage position, the stopper 214 cooperates with the rotary cover 213 to stop in the second direction, thereby limiting the rotation of the rotary cover 213 along the second direction, so as to achieve locking of the rotation of the rotary cover 213 along the second direction, so as to avoid the second end moving toward the outside of the cuff body 1 under the action of the subject's arm and the bracket 12, thereby increasing the stability of the cuff body 1 after it is tightly wrapped around the subject's arm.

[0105] When removing the cuff from the subject's arm, first pull the rotary cover 213, and then move the rotary cover 213 from the linkage position to the disconnection position. At this time, the rotary cover 213 releases the linkage cooperation with the winding disk 212, and the stopper 214 releases the stop cooperation with the rotary cover 213, and then the bracket 12 gradually recovers its deformation to gradually increase the diameter of the cuff body 1, and the cuff body 1 gradually separates from the subject's arm, and then apply a pulling force to the cuff body 1 away from the subject's arm to continue to increase the diameter of the cuff body 1, and finally separate the cuff body 1 from the subject's arm.

[0106] Furthermore, because the rotary cover 213 is released from the linkage with the winding disk 212 in the disconnected position, the rotary cover 213 cannot rotate along with the winding disk 212 when the cuff body 1 recovers its deformation in the direction of increasing its diameter, thereby reducing the force required for the cuff body 1 to recover its deformation in the direction of increasing its diameter, thereby reducing the difficulty for the subject to remove the cuff body 1 from the arm, thereby further improving the user experience of the subject.

[0107] In a preferred embodiment, the length L of the cuff body 1 satisfies: 37 cm ≤ L ≤ 40 cm; the length L3 of the reel cord 22 satisfies: 44 cm ≤ L3 ≤ 50 cm.

[0108] The present application does not specifically limit the structure of the anti-rotation member 214. Preferably, refer to Figure 6 , Figure 7 and Figure 8 The stop member 214 includes a ring body 237 snap-fitted with the base 211 and an elastic arm 238 arranged on the outer periphery of the ring body 237. The elastic arm 238 has a fixed end connected to the ring body 237 and a swing end opposite to the fixed end. The swing end can swing elastically around the fixed end, and a stop tooth 240 is arranged on the outer side of the swing end. A locking tooth 229 is arranged inside the rotary cover 213. When the rotary cover 213 is in the linkage position, the stop tooth 240 can move relative to the locking tooth 229 in the first direction and stop and cooperate with the locking tooth 229 in the second direction.

[0109] It can be understood that a plurality of locking teeth 229 are continuously arranged along the circumference of the rotary cover 213 , and the teeth of the locking teeth 229 face the center of the rotary cover 213 so as to be able to stop and cooperate with the stopping teeth 240 in the second direction.

[0110] When the cuff body 1 is rolled up so that the cuff body 1 tightly wraps around the arm of the subject, the rotary cover 213 is first pressed, and then the rotary cover 213 moves from the disconnected position to the linked position, and then the rotary cover 213 is twisted in the first direction, and the rotary cover 213 drives the locking tooth 229 to move. At this time, the swing end of the elastic arm 238 swings around the fixed end under the action of the locking tooth 229, so that the stop tooth 240 and the locking tooth 229 form a avoidance, thereby ensuring that the rotary cover 213 can rotate in the first direction, and finally the second end gradually extends into the opening 14. Inside the cuff body 1, and when the locking tooth 229 and the stop tooth 240 rotate relative to each other, the swinging end elastically swings around the fixed end, so that the stop tooth 240 and the locking tooth 229 continuously collide and make a clicking sound, so as to remind the subject that the stop member 214 has worked at this time, thereby avoiding the phenomenon that the subject finds that the stop member 214 is not working after the subject has tightly wrapped the cuff body 1 around the subject's arm, that is, avoiding the phenomenon that the subject needs to twist the rotary cover 213 again, thereby further improving the subject's wearing efficiency of the cuff.

[0111] Further, refer to Figure 8 , Fig.13 and Fig.15 The top of the base 211 has a through hole 219 , the hole wall of the through hole 219 is provided with a clamping portion 220 , and the bottom of the ring body 237 is provided with a matching portion 239 that is clamped and matched with the clamping portion 220 .

[0112] When assembling the stop member 214, first align the mating portion 239 with the snap-on portion 220, and then apply pressure to the stop member 214 in the direction of the base 211 to make the mating portion 239 and the snap-on portion 220 snap-fit ​​together to complete the assembly of the stop member 214. During this process, it is only necessary to press the stop member 214, thereby reducing the difficulty of assembling the stop member 214 and ensuring the connection stability between the stop member 214 and the base 211; and, compared with setting the stop member 214 and the base 211 as an integrated structure, the production difficulty of the base 211 is reduced, the yield rate of the base 211 is improved, and the production cost of the base 211 is greatly reduced.

[0113] Further, refer to Figure 8 , Fig.13 and Fig.15The hole wall of the through hole 219 is provided with an avoidance groove 221, the clamping part 220 is arranged on the groove wall of the avoidance groove 221, and at least a part of the matching part 239 is located in the avoidance groove 221, so that after the matching part 239 and the clamping part 220 are clamped together, the groove wall of the avoidance groove 221 can cooperate with the matching part 239 stopper to avoid the phenomenon that the anti-rotation member 214 may rotate relative to the base 211, thereby ensuring the anti-rotation effect of the anti-rotation member 214 on the rotary cover 213 in the second direction, so as to ensure the stability of the cuff after tightly wrapping the arm of the subject, and thus ensure the accuracy of blood pressure measurement; and it can also simplify the structural design of the clamping part 220 and the matching part 239, so as to further reduce the production difficulty of the anti-rotation member 214 and the base 211, improve the production efficiency of the anti-rotation member 214 and the base 211 and reduce the production cost.

[0114] The present application does not specifically limit the structures of the clamping portion 220 and the matching portion 239. Preferably, refer to Fig.13 and Fig.15 The clamping portion 220 is a block structure provided on the wall of the avoidance groove 221, and the matching portion 239 is an L-shaped structure provided on the bottom of the ring body 237, so that the L-shaped structure and the block structure are clamped and matched to realize the fixed connection of the anti-rotation member 214 to the base 211. In other embodiments, the clamping portion 220 and the matching portion 239 can also be other structures that can be clamped and matched with each other.

[0115] In other embodiments, the stop member 214 can also be a toothed structure arranged at the top edge of the base 211, and the base 211 is provided with an elastic member for driving the toothed structure to move along the central axis direction of the base 211, that is, the teeth of the toothed structure are facing in the direction away from the bottom of the base 211, and the teeth of the locking teeth 229 are facing the base 211, so that when the rotary cover 213 rotates along the first direction, the toothed structure applies pressure to the elastic member under the action of the locking teeth 229, the elastic member is deformed, and the toothed structure moves in the direction away from the rotary cover 213 to form a avoidance with the locking teeth 229. When the rotary cover 213 stops rotating in the first direction, the toothed structure is reset under the action of the elastic member and cooperates with the locking teeth 229 to stop in the second direction, thereby preventing the rotary cover 213 from rotating in the second direction.

[0116] The present application does not specifically limit the linkage mode between the rotary cover 213 and the winding disk 212. Preferably, refer to Figure 5 , Fig. 9 , Fig.10 and Fig.11The rotary cover 213 is clamped with an active disk 230 that can extend into the interior of the ring body 237, a driving tooth 323 is provided on the side of the active disk 230, a through hole 219 is provided on the top of the base 211, and a driven tooth 225 that extends into the through hole 219 is provided on the top of the winding disk 212. When the rotary cover 213 is in the linkage position, the driving tooth 323 meshes with the driven tooth 225.

[0117] When the cuff body 1 is to be rolled up, the rotary cover 213 is first pressed to move the rotary cover 213 from the disconnected position to the linked position, at which time the active tooth 323 is meshed with the driven tooth 225, and then the rotary cover 213 is twisted along the first direction, the rotary cover 213 drives the active disk 230 to rotate, so that the active disk 230 drives the winding disk 212 to rotate under the action of the active tooth 323 and the driven tooth 225, and the winding disk 212 winds up the winding rope 22, so that the winding rope 22 applies a pulling force to the second end, and the second end gradually enters the interior of the cuff body 1 through the opening 14 to achieve the winding of the cuff body 1.

[0118] Since the active disk 230 is clamped on the rotary cover 213 , the production difficulty of the rotary cover 213 is reduced, the yield rate of the rotary cover 213 is improved, and the production cost of the rotary cover 213 is reduced.

[0119] In addition, since the active tooth 323 is arranged on the side of the active disk 230, when the rotary cover 213 is in the linkage position, the driven tooth 225 is located on the peripheral side of the active disk 230, so that the winding disk 212 can position the active disk 230 to increase the stability of the active disk 230, thereby ensuring the winding efficiency of the cuff body 1.

[0120] Of course, in other embodiments, the driving teeth 232 may also be disposed at the bottom of the driving disk 230 .

[0121] Further, see Fig.10 and Fig.11 The active disk 230 has a center hole 233, and the hole wall of the center hole 233 is provided with a convex rib 234. The top of the winding disk 212 is provided with a limiting arm 226 extending into the center hole 233, and the outer side of the limiting arm 226 is provided with a limiting protrusion 227. When the rotary cover 213 is in the linkage position, the limiting protrusion 227 is located above the convex rib 234. When the rotary cover 213 is in the disconnection position, the limiting protrusion 227 is located below the convex rib 234.

[0122] Since the active disk 230 has a center hole 233, a limiting arm 226 extending into the center hole 233 is provided on the top of the winding disk 212, so that the cooperation between the limiting arm 226 and the center hole 233 can realize the mutual positioning of the active disk 230 and the winding disk 212, so as to ensure that when the rotary cover 213 is in the linkage position, the active tooth 323 can mesh with the driven tooth 225, thereby ensuring the winding efficiency of the cuff body 1.

[0123] In addition, since the hole wall of the center hole 233 is provided with a rib 234 and the outer side of the limit arm 226 is provided with a limit protrusion 227, when the rotary cover 213 is in the linkage position, the limit protrusion 227 is located above the rib 234, and when the rotary cover 213 is in the disconnection position, the limit protrusion 227 is located below the rib 234, so that when the rotary cover 213 moves from the disconnection position to the linkage position, the limit arm 226 can collide with the rib 234 to make a sound to warn the user that the rotary cover 213 has moved to the linkage position. Similarly, when the rotary cover 213 moves from the linkage position to the disconnection position, the limit arm 226 will also collide with the rib 234 to make a sound to warn the user that the rotary cover 213 has moved to the disconnection position, so as to avoid the phenomenon that the rotary cover 213 is separated from the base 211 due to the user's excessive operation on the rotary cover 213, thereby further improving the user experience of the subject.

[0124] In addition, when the rotary cover 213 is in the linkage position, the limit protrusion 227 is located above the rib 234, and when the rotary cover 213 is in the disconnection position, the limit protrusion 227 is located below the rib 234. Then, the cooperation between the limit protrusion 227 and the rib 234 can be utilized to limit the rotary cover 213 in the linkage position or the disconnection position, so as to increase the stability of the rotary cover 213 in the linkage position or the disconnection position, so as to achieve the effect of facilitating the subject to operate the cuff, thereby further improving the user experience of the subject.

[0125] Further, refer to Fig.11 At least two limiting arms 226 are arranged along the circumference of the center hole 233, guide surfaces are arranged on both the top and bottom sides of the rib 234, and matching surfaces that can cooperate with the guide surfaces are arranged on both the top and bottom sides of the limiting protrusion 227.

[0126] Since at least two limiting arms 226 are arranged along the circumference of the center hole 233, the positioning effect of the limiting arms 226 and the convex rib 234 on the active disk 230 and the winding disk 212 is increased; and guide surfaces are arranged on both sides of the top and bottom walls of the convex rib 234, and matching surfaces that can cooperate with the guide surfaces are arranged on both sides of the top and bottom of the limiting protrusion 227, thereby reducing the force required for pulling or pressing the rotary cover 213, so as to achieve the effect of facilitating the operation of the rotary cover 213 by the subject, thereby further improving the user experience of the subject; at the same time, the existence of the guide surface and the matching surface avoids the phenomenon that the clamping force between the limiting protrusion 227 and the convex rib 234 is too large, which affects the connection stability of the active disk 230 and the rotary cover 213, thereby ensuring the connection stability of the active disk 230 and the rotary cover 213.

[0127] Preferably, two limiting arms 226 are arranged relatively to each other, and the two limiting arms 226 are arranged at an interval, so that a deformation space for the limiting arms 226 to deform is formed between the two limiting arms 226, so as to ensure the movement of the rotary cover 213 between the linkage position and the disconnection position.

[0128] Further, refer to Figure 7 and Fig.10 The rotary cover 213 is provided with a snap-fitting portion 231 that can extend into the interior of the ring body 237, and the outer periphery of the active disk 230 is provided with a fixing portion 235 that snaps with the snap-fitting portion 231. Then, on the one hand, the snap-fitting between the active disk 230 and the rotary cover 213 is realized, and on the other hand, the active disk 230 is fixed on the outside so that the snap-fitting portion 231 and the fixing portion 235 are avoided with the limiting arm 226, thereby making the structure of the winding mechanism 2 more compact, reducing the size of the winding mechanism 2, and achieving the effect of facilitating the storage of the cuff; in addition, it is also convenient for the assembler to observe whether the active disk 230 is installed in place to ensure the production quality of the cuff.

[0129] The present application does not specifically limit the structures of the engaging portion 231 and the fixing portion 235. Figure 7 and Fig.10 The engaging portion 231 is an L-shaped structure provided on the rotary cover 213, a concave groove is provided on the outer periphery of the active disk 230, and the fixing portion 235 is a block structure provided on the wall of the concave groove. The L-shaped structure can be engaged with the block structure, and after the L-shaped structure and the block structure are engaged together, the L-shaped structure can be hidden in the concave groove to further reduce the size of the winding mechanism 2. At the same time, the wall of the concave groove can also cooperate with the L-shaped structure stopper to avoid the phenomenon of relative rotation between the active disk 230 and the rotary cover 213, thereby ensuring the winding efficiency of the cuff body 1. In other implementation examples, the engaging portion 231 and the fixing portion 235 can also be other structures that can be engaged with each other.

[0130] Furthermore, the thickness of the stop member 214, the thickness of the locking tooth 229, the height of the driving tooth 323 and the height of the driven tooth 225 are all smaller than the distance between the linkage position and the disconnection position, so that after the rotary cover 213 moves from the linkage position to the disconnection position, the stop member 214 can be separated from the locking tooth 229, and the driving tooth 323 can be separated from the driven tooth 225, to ensure that when the rotary cover 213 is in the disconnection position, the winding reel 212 can rotate in the second direction to facilitate the subject to remove the cuff from the arm.

[0131] In other embodiments, the rotary cover 213 is provided with a first linkage shaft, and the winding disk 212 is provided with a second linkage shaft. The first linkage shaft and the second linkage shaft are arranged opposite to each other and both are provided with groove structures that can be snap-fitted with each other. That is to say, when the rotary cover 213 is in the linkage position, the first linkage shaft and the second linkage shaft are coaxial and snap-fitted, so that the rotary cover 213 can drive the winding disk 212 to rotate, and when the rotary cover 213 is in the disconnected position, the first linkage shaft and the second linkage shaft are separated to release the linkage between the two.

[0132] The present application does not specifically limit the structure of the base 211. Preferably, refer to Figure 5 , Fig.13 , Fig.14 and Fig.15 The base 211 includes a base body 215 and a shell 216 clamped inside the base body 215 . The base body 215 and the shell 216 together form a receiving cavity for receiving the winding reel 212 .

[0133] When assembling the winding drum 212, the winding drum 212 is first placed inside the shell 216, and then the base 211 is installed so that the shell 216 and the seat body 215 are snap-fitted together, thereby achieving the shell 216 being able to block the winding drum 212 while reducing the difficulty of assembling the winding drum 212, thereby improving the assembly efficiency of the winding drum 212, and further improving the production efficiency of the winding mechanism 2.

[0134] It can be understood that the above-mentioned through hole 219 is disposed on the top of the housing 216 .

[0135] The present application does not specifically limit the snap-fitting method of the housing 216 and the base 215. Preferably, the housing 216 is provided with a block structure on the outside, and the base 215 is provided with a groove structure for accommodating the block structure on the inside, so as to realize the snap-fitting of the housing 216 and the base 215 by snap-fitting the block structure and the groove structure. In other implementation examples, the housing 216 can also be snap-fitted with the base 215 by other snap-fitting structures.

[0136] Further, see Figure 5 , Fig.13 , Fig.14 and Fig.15 The shell 216 is provided with a threading hole for the winding rope 22 to pass through, and the outer part of the shell 216 is provided with a guide rib 222 corresponding to the threading hole, and the seat body 215 is provided with a limiting notch 217 for accommodating the guide rib 222.

[0137] When assembling the winding drum 212, first pass the winding rope 22 through the guide rib 222 and the threading hole, then connect the winding rope 22 to the winding drum 212, and then place the winding drum 212 in the shell 216, and then align the guide rib 222 with the limiting notch 217, and then apply a force to the base 211 in the direction of the shell 216, so that the shell 216 is clamped in the inside of the base 211, and the guide rib 222 is located in the limiting notch 217, so that the cooperation between the guide rib 222 and the limiting notch 217 limits the relative rotation of the shell 216 and the base 211, so as to ensure the limiting effect of the stopper 214 on limiting the rotation of the rotary cover 213 in the second direction; at the same time, the setting of the guide rib 222 can also realize the guidance of the winding rope 22, so as to reduce the friction of the winding rope 22, thereby extending the service life of the winding rope 22, and then achieving the effect of extending the service life of the cuff.

[0138] Further, refer to Figure 4 and Figure 5 A decorative ring 23 is sleeved on the outside of the seat body 215 , and the guide ribs 222 extend to the outside of the seat body 215 . The decorative ring 23 is located at the bottom of the guide ribs 222 , so that the guide ribs 222 can apply an extrusion force on the decorative ring 23 away from the direction of the rotating cover 213 .

[0139] Since the outer sleeve of the seat body 215 is provided with a decorative ring 23, the decorative ring 23 can cover the gap between the seat body 215 and the outer peripheral layer 132 and the connection trace between the seat body 215 and the bracket 12, so as to improve the product quality of the cuff and further improve the user experience of the subject; at the same time, the guide rib 222 extends to the outside of the seat body 215, and the decorative ring 23 is located at the bottom of the guide rib 222, so that the guide rib 222 can apply an extrusion force to the decorative ring 23 away from the direction of the screw cover 213, so as to utilize the extrusion force of the guide rib 222 to fix the decorative ring 23, thereby reducing the difficulty of fixing the decorative ring 23 and avoiding the need to design a separate fixing structure for the decorative ring 23, so as to simplify the structural design of the winding mechanism 2.

[0140] Further, refer to Fig.14 and Fig.15 One of the seat body 215 and the shell body 216 is provided with a positioning groove 218, and the other of the two is provided with a positioning rib 223 extending into the positioning groove 218.

[0141] When assembling the shell 216, first align the positioning rib 223 with the positioning groove 218, and then apply pressure to the base 211 in the direction close to the shell 216, so that the positioning rib 223 extends into the positioning groove 218, so as to utilize the plug-in fit between the positioning rib 223 and the positioning groove 218 to achieve the limitation of the relative rotation of the shell 216 and the base 211, thereby further increasing the limiting effect of the stop member 214 on the rotation of the rotary cover 213 along the second direction.

[0142] Specifically, a positioning groove 218 is disposed inside the seat body 215 , and a positioning rib 223 is disposed on the outer periphery of the shell 216 .

[0143] In other embodiments, the base 211 may also be an integrated structure, and the bottom of the base 211 is open so that the winding reel 212 can be installed from the bottom of the base 211 to the inside of the base 211 .

[0144] In a preferred embodiment, referring to Figure 1 and Figure 2 An even number of first connection holes are arranged at intervals on the second end, and the winding rope 22 is passed through the multiple first connection holes. Two second connection holes are arranged in the middle part of the cuff body 1 in the length direction, and the two ends of the winding rope 22 extend out of the outside of the cuff body 1 through the two second connection holes and are connected to the winding drum 212.

[0145] Specifically, the second connection hole is provided in the outer peripheral layer 132 , so that the reeling rope 22 located between the bracket 12 and the outer peripheral layer 132 extends to the outside of the cuff body 1 through the second connection hole provided on the outer peripheral layer 132 .

[0146] Since an even number of first connecting holes are arranged at intervals at the second end, the winding rope 22 is passed through the plurality of first connecting holes, and the two ends of the winding rope 22 extend out of the cuff body 1 through the two second connecting holes respectively and are connected to the winding drum 212, thereby dividing the winding rope 22 into three sections, the two sections at the ends are used to apply tension to the second end, and the end in the middle is used to connect to the first connecting hole, so that the second end can be balanced in force to avoid the phenomenon that the second end of the winding rope 22 is deflected when the second end is pulled, further increasing the smoothness of the movement of the second end to reduce the difficulty of the subject in winding up the cuff body 1, thereby further improving the user experience of the subject.

[0147] In addition, since there are an even number of first connecting holes, after the winding rope 22 is passed through multiple first connecting holes, the parts of the winding rope 22 extending toward the winding mechanism 2 are all located on the same side of the second end, so as to further ensure the force balance of the second end.

[0148] Preferably, two first connecting holes are provided at intervals to ensure balanced force on the second end while reducing the number of holes on the cuff body 1 .

[0149] In a preferred embodiment, referring to Fig.12 The winding drum 212 is provided with at least two rows of fixing holes 228. The winding rope 22 is passed through one row of fixing holes 228 and then folded back and passed through the other row of fixing holes 228, thereby increasing the connection stability between the winding rope 22 and the winding drum 212, avoiding the phenomenon that the winding rope 22 may be separated from the winding drum 212, so as to ensure the service life of the cuff.

[0150] It is understandable that two rows of fixing holes 228 are provided at both ends of the winding drum 212 corresponding to the winding rope 22 to ensure the connection stability between the winding ropes 22 and the winding ropes 22.

[0151] Preferably, the fixing holes 228 are arranged in two rows to ensure the stability of the connection between the winding rope 22 and the winding drum 212 while reducing the difficulty of installing the winding rope 22 .

[0152] In a preferred embodiment, referring to Figure 7 and Fig.15 The interior of the rotary cover 213 is provided with a limiting rib 236 extending along its circumference, and the exterior of the base 211 is provided with a blocking rib 224 extending along its circumference, so that the limiting rib 236 and the blocking rib 224 can cooperate with each other to limit the rotary cover 213, so as to avoid the rotary cover 213 from separating from the base 211 due to transitional movement, thereby increasing the connection stability between the rotary cover 213 and the base 211; when the rotary cover 213 is in the disconnected position, the limiting rib 236 and the blocking rib 224 cooperate with each other to remind the subject that the rotary cover 213 has moved to the disconnected position, so that the subject can proceed to the next step of operation, thereby further improving the user experience of the subject.

[0153] Specifically, the blocking rib 224 is disposed on the side of the shell 216 and located on the top of the shell 216 .

[0154] The present application does not make any specific limitation on the extension method of the limiting rib 236 and the blocking rib 224. They can be strip structures that extend continuously along the circumferential direction; they can also be strip structures in which one of them extends intermittently along the circumferential direction, and the other of them is a strip structure that extends continuously along the circumferential direction.

When the cuff body 1 is wound up, the knob is turned so that the knob drives the gear to rotate, and the gear drives the winding belt to rotate under the action of the meshing teeth, so that the winding belt pulls the second end, so that the second end moves toward the inside of the cuff body 1 through the opening 14, so as to realize the winding of the cuff body 1.

[0156] The present application also discloses a sphygmomanometer, which includes a sphygmomanometer body, a pipeline and a cuff as described above, wherein the pipeline is used to connect the sphygmomanometer body and the cuff.
