Description

Technical Field

[0001] This invention belongs to the field of blood pressure monitor technology, specifically a blood pressure monitor connector assembly. Background Technology

[0002] A blood pressure monitor works by measuring the pressure of a cuff applied to block blood flow, then using a pressure sensor to detect fluctuations in blood flow as it is restored, thereby calculating systolic and diastolic blood pressure. Modern electronic blood pressure monitors mostly use the oscillometric method, while traditional mercury sphygmomanometers are based on the Korotkoff sound method. The core principle of both revolves around the correlation between changes in arterial blood flow and pressure.

[0003] Most existing blood pressure monitors consist of a monitor body, a measuring cuff, and a tubing connecting the monitor body and the cuff. When measuring blood pressure, the cuff is strapped to the user's arm. The monitor's built-in pump then pressurizes the cuff via the tubing, completely blocking arterial blood flow. The cuff then slowly deflates. When blood flow resumes, the vibration or sound change in the blood vessel wall is detected by a sensor and converted into a pressure reading. Currently, the tubing connecting the monitor body and cuff is constantly exposed when not in use. This exposure makes the tubing susceptible to aging due to long-term exposure to moisture and air, and it is also prone to accidental damage. Therefore, the tubing in existing blood pressure monitors has poor protection, resulting in a relatively limited lifespan. Summary of the Invention

[0004] In view of the shortcomings of the prior art, the technical problem to be solved by the embodiments of the present invention is to provide a blood pressure monitor connector assembly.

[0005] To solve the above-mentioned technical problems, the present invention provides the following technical solution:

[0006] A blood pressure monitor connector assembly includes a blood pressure monitor body, a measuring cuff, a flexible air tube, a winding reel, a pushing assembly, a driving assembly, and an air supply assembly.

[0007] One end of the flexible tubing extends into the interior of the blood pressure monitor body and is connected to the winding reel, while the other end extends into the exterior of the blood pressure monitor body and is connected to the measuring cuff.

[0008] The air supply assembly is installed inside the blood pressure monitor body and is used to supply air into the flexible air tube.

[0009] The winding wheel is disposed inside the body of the blood pressure monitor, and the drive assembly is mounted on the inner wall of the body of the blood pressure monitor for driving the winding wheel to rotate, thereby winding up the flexible tubing.

[0010] The pushing component is disposed on the side wall of the blood pressure monitor body. After the winding wheel has finished winding the flexible air tube, the pushing component is used to push the flexible air tube away from the outside of the winding wheel.

[0011] As a further improvement of the present invention: a support shaft is fixedly provided at one end of the winding reel.

[0012] The drive assembly includes a drive gear, a first support plate, a drive motor, and a transmission gear.

[0013] The first support plate is fixedly installed on the inner side wall of the blood pressure monitor body. The end of the support shaft away from the winding wheel passes through the first support plate and rotates with the first support plate. The drive motor is fixedly installed on the side wall of the first support plate. The drive gear is fixedly disposed at the output end of the drive motor. The transmission gear is fixedly disposed outside the support shaft and meshes with the drive gear.

[0014] As a further improvement of the present invention: the take-up reel has a first chamber inside, and the support shaft has a second chamber communicating with the first chamber.

[0015] The end of the flexible air tube furthest from the measuring cuff is connected to the circumferential side wall of the take-up reel and communicates with the first chamber.

[0016] The air supply assembly includes an air pump and a rigid air pipe.

[0017] The air pump is fixedly installed on the inner wall of the blood pressure monitor body. One end of the rigid air tube is connected to the air outlet of the air pump, and the other end is connected to the support shaft through a rotary joint. The rigid air tube is connected to the second chamber.

[0018] As a further improvement of the present invention: a pressure block is provided on the side wall of the measuring cuff.

[0019] The material pushing assembly includes a pressing push rod, a support, a push block, and an annular pushing plate.

[0020] The annular push plate is movably sleeved on the circumferential side wall of the winding wheel. One end of the pressure push rod extends to the outside of the blood pressure monitor body, and the other end extends to the inside of the blood pressure monitor body and is fixedly connected to the support. The push block is fixedly set at the bottom of the support. The push block is located on the side of the winding wheel, and the end of the push block facing the annular push plate is provided with an inclined surface.

[0021] As a further improvement of the present invention: the support is connected to the inner side wall of the blood pressure monitor body by a first elastic element, which is used to provide elastic tension to the support.

[0022] As a further improvement of the present invention: an elastic reset component is also provided on one side of the winding reel.

[0023] When the first elastic element pulls the support so that the pressing push rod and the push block move away from the winding wheel, the elastic reset assembly drives the annular push plate to move in the opposite direction along the axial direction of the winding wheel, thereby resetting the annular push plate.

[0024] As a further improvement of the present invention: the elastic reset assembly includes a second support plate, a guide rod, a second elastic element, and a limiting end block.

[0025] One end of the second support plate is fixedly connected to the outer wall of the support shaft, and the other end extends to the side of the annular push plate. One end of the guide rod is fixedly connected to the annular push plate, and the other end passes through the second support plate and is fixedly connected to the limiting end block.

[0026] The guide rod is movably engaged with the second support plate. One end of the second elastic element is connected to the second support plate, and the other end is connected to the limiting end block, which is used to provide elastic support for the limiting end block.

[0027] As a further improvement of the present invention: the first elastic element and the second elastic element are springs or metal sheets.

[0028] As a further improvement of the present invention: a connector is provided on the side wall of the measuring cuff.

[0029] As a further improvement of the present invention: the connector is a Velcro or a snap fastener.

[0030] Compared with the prior art, the beneficial effects of the present invention are:

[0031] In this embodiment of the invention, when using the blood pressure monitor, the operator wraps the measuring cuff around the user's arm. Then, the inflation component supplies air into the flexible tubing. The air enters the air bladder inside the measuring cuff through the flexible tubing, causing the bladder to inflate and thus block the blood vessels in the user's arm to measure blood pressure. After the blood pressure measurement is completed, the drive component rotates the winding wheel. As the winding wheel rotates, it winds up the flexible tubing, drawing it into the main body of the blood pressure monitor and wrapping it around the outside of the winding wheel. This achieves the storage and protection of the flexible tubing, preventing prolonged exposure and reducing the probability of accidental damage, thereby extending its service life. Once the flexible tubing is wrapped around the winding wheel, the... The delivery component pushes the flexible tubing, removing it from the outside of the reel. When the blood pressure monitor needs to be used later, the operator simply pulls the measuring cuff, which moves the flexible tubing outwards from the monitor body. Since the flexible tubing is no longer wound around the reel, its movement is not restricted. The operator only needs to apply a small amount of force to pull the tubing out, effectively preventing breakage due to excessive tension. Compared to existing technologies, this method provides protective storage for the flexible tubing, preventing prolonged exposure and accidental damage, and extending its lifespan.

Detailed Implementation

[0041] The technical solution of the present invention will be further described in detail below with reference to specific embodiments.

[0042] Embodiments of the present invention are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

Therefore, they should not be construed as limitations on this invention.

[0044] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "setting" should be interpreted broadly. For example, they can refer to a fixed connection or setting, a detachable connection or setting, or an integral connection or setting. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0045] Please see Figure 1 , Figure 2 as well as Figure 3 This embodiment provides a blood pressure monitor connector assembly, including a blood pressure monitor body 10, a measuring cuff 20, a flexible air tube 30, a winding wheel 40, a pushing component 50, a driving component 60, and an air supply component 70. One end of the flexible air tube 30 extends into the blood pressure monitor body 10 and is connected to the winding wheel 40, while the other end extends into the outside of the blood pressure monitor body 10 and is connected to the measuring cuff 20. The air supply component 70 is installed inside the blood pressure monitor body 10 and is used to supply air into the flexible air tube 30. The winding wheel 40 is disposed inside the blood pressure monitor body 10. The driving component 60 is installed on the inner wall of the blood pressure monitor body 10 and is used to drive the winding wheel 40 to rotate in order to wind up the flexible air tube 30. The pushing component 50 is disposed on the side wall of the blood pressure monitor body 10. After the winding wheel 40 has finished winding up the flexible air tube 30, the pushing component 50 is used to push the flexible air tube 30 away from the outside of the winding wheel 40.

[0046] When using the blood pressure monitor, the operator wraps the measuring cuff 20 around the user's arm. The inflation component 70 then supplies air into the flexible tubing 30. The air enters the air bladder inside the measuring cuff 20 through the flexible tubing 30, causing the bladder to inflate and block the blood vessels in the user's arm to measure blood pressure. After the blood pressure measurement is complete, the drive component 60 rotates the winding wheel 40. As the winding wheel 40 rotates, it winds up the flexible tubing 30, drawing it inside the blood pressure monitor body 10 and wrapping it around the winding wheel 40. This provides protection and prevents the flexible tubing 30 from prolonged exposure, reducing the probability of accidental damage and extending its lifespan. The service life of the flexible air tube 30: After the flexible air tube 30 is wound around the outside of the take-up reel 40, the push component 50 pushes the flexible air tube 30, causing the flexible air tube 30 to be removed from the outside of the take-up reel 40. In this way, when the blood pressure monitor needs to be used later, the operator only needs to pull the measuring cuff 20. The measuring cuff 20 drives the flexible air tube 30 to move and extend outward from the blood pressure monitor body 10. At this time, since the flexible air tube 30 is no longer wound around the outside of the take-up reel 40, the movement of the flexible air tube 30 outward from the blood pressure monitor body 10 is not restricted by the take-up reel 40. The operator only needs to exert a small pulling force to pull the flexible air tube 30 outward from the inside of the blood pressure monitor body 10, thereby effectively avoiding the flexible air tube 30 being subjected to a large pulling force and thus breaking and being damaged.

[0047] Please see Figure 6In one embodiment, a support shaft 401 is fixedly provided at one end of the take-up reel 40. The drive assembly 60 includes a drive gear 601, a first support plate 602, a drive motor 603, and a transmission gear 604. The first support plate 602 is fixedly installed on the inner side wall of the blood pressure monitor body 10. The end of the support shaft 401 away from the take-up reel 40 passes through the first support plate 602 and rotates with the first support plate 602. The drive motor 603 is fixedly installed on the side wall of the first support plate 602. The drive gear 601 is fixedly provided at the output end of the drive motor 603. The transmission gear 604 is fixedly provided outside the support shaft 401 and meshes with the drive gear 401.

[0048] After the user completes the blood pressure measurement, the staff starts the drive motor 603. The drive motor 603 drives the drive gear 601 to rotate. Through the meshing of the drive gear 601 and the transmission gear 604, the support shaft 401 rotates relative to the first support plate 602. The support shaft 401 drives the winding wheel 40 to rotate. When the winding wheel 40 rotates, it winds up the flexible air tube 30. When the flexible air tube 30 is wound up, it moves into the body of the blood pressure monitor 10 and is wound around the circumferential side wall of the winding wheel 40, thereby realizing the storage and protection of the flexible air tube 30.

[0049] Please see Figure 5 as well as Figure 7 In one embodiment, the take-up reel 40 has a first chamber (not shown in the figure), the support shaft 401 has a second chamber communicating with the first chamber, one end of the flexible air tube 30 away from the measuring cuff 20 is connected to the circumferential side wall of the take-up reel 40 and communicates with the first chamber, the air supply assembly 70 includes an air pump 701 and a rigid air tube 702, the air pump 701 is fixedly installed on the inner wall of the blood pressure monitor body 10, one end of the rigid air tube 702 is connected to the air outlet of the air pump 701, and the other end is connected to the support shaft 401 through a rotary joint, and the rigid air tube 702 communicates with the second chamber.

[0050] After the staff wraps the measuring cuff 20 around the user's arm, they start the air pump 701. The air pump 701 fills the rigid air tube 702 with air. The air enters the second chamber through the rigid air tube 702, and then enters the first chamber from the second chamber. After entering the first chamber, the air enters the air bladder built into the measuring cuff 20 through the flexible air tube 30, thereby causing the air bladder to inflate and block the blood vessels in the user's arm to measure blood pressure. After the measurement is completed, the drive motor 603 drives the drive gear 601 to rotate. Through the meshing of the drive gear 601 and the transmission gear 604, the support shaft 401 and the winding wheel 40 rotate. The winding wheel 40 winds up the flexible air tube 30 to achieve storage and protection of the flexible air tube 30. When the support shaft 401 rotates, it rotates relative to the rigid air tube 702 with the help of the rotary joint.

[0051] Please see Figure 1 , Figure 4 , Figure 6 as well as Figure 7 In one embodiment, a pressure block 201 is provided on the side wall of the measuring cuff 20. The pushing assembly 50 includes a pressure push rod 501, a support 502, a push block 504, and an annular push plate 505. The annular push plate 505 is movably sleeved on the circumferential side wall of the take-up wheel 40. One end of the pressure push rod 501 extends to the outside of the blood pressure monitor body 10, and the other end extends to the inside of the blood pressure monitor body 10 and is fixedly connected to the support 502. The push block 504 is fixedly disposed at the bottom of the support 502. The push block 504 is located on the side of the take-up wheel 40, and one end of the push block 504 facing the annular push plate 505 is provided with an inclined surface.

[0052] Initially, the annular push plate 505 is located at one end outside the winding wheel 40. When the drive motor 603 drives the drive gear 601 to rotate, thereby driving the winding wheel 40 to rotate, the flexible air tube 303 is wound around the circumferential side wall of the winding wheel 40 and located on one side of the annular push plate 505. During the winding process, the flexible air tube 30 pulls the measuring cuff 20 closer to the blood pressure monitor body 10. When the measuring cuff 20 acts on the outer wall of the blood pressure monitor body 10, the pressure block 201 acts on the end of the pressure push rod 501 located outside the blood pressure monitor body 10, thereby pushing the pressure push rod 501 to move into the blood pressure monitor body 10. When the pressure push rod 501 moves, it drives the support 502 and the push block 504 to move. When the push block 504 moves, the inclined surface at one end acts on the annular push plate. Plate 505, and then applies a pushing force to the annular push plate 505. When the annular push plate 505 is pushed, it moves along the axial direction of the take-up wheel 40, thereby pushing the flexible air tube 30 wound around the outside of the take-up wheel 40 away from the other end of the take-up wheel 40. At this time, the flexible air tube 30 is in a loose state inside the blood pressure monitor body 10. Thus, when the blood pressure monitor is used in the future and the flexible air tube 30 is pulled to move the flexible air tube 30 to the outside of the blood pressure monitor body 10, the end of the flexible air tube 30 inside the blood pressure monitor body 10 is in a state of no force. The flexible air tube 30 can be easily pulled out from inside the blood pressure monitor body 10, thereby avoiding the flexible air tube 30 being damaged due to excessive tension caused by being wound around the circumferential side wall of the take-up wheel 40.

[0053] Please see Figure 4 In one embodiment, the support 502 is further connected to the inner sidewall of the blood pressure monitor body 10 by a first elastic element 503, which provides elastic tension to the support 502.

[0054] When the pressure block 201 pushes the pressure push rod 501, thereby causing the support 502 and the push block 504 to move, the first elastic element 503 is stretched by force. When the blood pressure monitor is used and the measuring cuff 20 is pulled, the pressure block 201 on the side wall of the measuring cuff 20 moves away from the blood pressure monitor body 10. At this time, the first elastic element 503 pulls the support 502, causing the support 502 and the push block 504 to move away from the winding wheel 40. When the support 502 moves away from the winding wheel 40, it drives the pressure push rod 501 to move outward from the blood pressure monitor body 10, thereby realizing the reset of the push block 504 and the pressure push rod 501.

[0055] Please see Figure 6In one embodiment, an elastic reset component 80 is also provided on one side of the take-up reel 40. When the first elastic element 503 pulls the support 502 so that the pressing push rod 501 and the push block 504 move away from the take-up reel 40, the elastic reset component 80 is used to drive the annular push plate 505 to move in the opposite direction along the axial direction of the take-up reel 40, thereby realizing the reset of the annular push plate 505. After the annular push plate 505 is reset, the take-up reel 40 can smoothly rewind the flexible air tube 30 again when it rotates subsequently.

[0056] Please see Figure 6 In one embodiment, the elastic reset assembly 80 includes a second support plate 801, a guide rod 802, a second elastic element 803, and a limiting end block 804. One end of the second support plate 801 is fixedly connected to the outer wall of the support shaft 401, and the other end extends to the side of the annular push plate 505. One end of the guide rod 802 is fixedly connected to the annular push plate 505, and the other end passes through the second support plate 801 and is fixedly connected to the limiting end block 804. The guide rod 802 is movably engaged with the second support plate 801. One end of the second elastic element 803 is connected to the second support plate 801, and the other end is connected to the limiting end block 804, for providing elastic support to the limiting end block 804.

[0057] When the inclined surface at one end of the push block 504 acts on the annular push plate 505, causing the annular push plate 505 to move axially along the winding wheel 40, the annular push plate 505 drives the guide rod 802 to move relative to the second support plate 801. The guide rod 802 drives the limiting end block 804 to move synchronously, and the second elastic element 803 is compressed by force. When the first elastic element 503 pulls the support 502, causing the push rod 501 and the push block 504 to move away from the winding wheel 40, the second elastic element 803 pushes the limiting end block 804. The limiting end block 804 drives the guide rod 802 to move in the opposite direction relative to the second support plate 801. The guide rod 802 drives the annular push plate 505 to move in the opposite direction along the winding wheel 40, thereby resetting the annular push plate 505.

[0058] In one embodiment, the first elastic element 503 and the second elastic element 803 can be springs or metal sheets, and there is no limitation here.

[0059] Please see Figure 3 In one embodiment, a connector 202 is provided on the side wall of the measuring cuff 20.

[0060] After the measuring cuff 20 is wrapped around the user's arm, it can be connected and limited using the connector 202, thus securing the measuring cuff 20. After the flexible air tube 30 is wound around the circumferential side wall of the take-up reel 40, the measuring cuff 20 is positioned close to the blood pressure monitor body 10. At this point, the operator can wrap the measuring cuff 20 around the outside of the blood pressure monitor body 10, and then again use the connector 202 for connection and limitation, so that the measuring cuff 20 wraps around the blood pressure monitor body 10, thereby protecting the blood pressure monitor body 10 and preventing accidental damage to the display screen and corresponding buttons on the blood pressure monitor body 10.

[0061] In one embodiment, the connector 202 can be a Velcro strap or a snap fastener; there is no limitation on this.

[0062] The working principle of this invention is as follows:

[0063] During blood pressure measurement, the flexible tubing 30 is extended outside the blood pressure monitor body 10. The operator wraps the measuring cuff 20 around the user's arm and secures it with the connector 202. Then, the air pump 701 is activated, supplying air into the rigid tubing 702. The air passes sequentially through the second chamber, the first chamber, and the flexible tubing 303 into the air bladder inside the measuring cuff 20, causing the bladder to inflate and block the blood vessels in the user's arm. After the blood pressure measurement is complete, the operator removes the measuring cuff 20 from the user's arm and activates the drive motor 603. The drive motor 603 drives the drive gear 601 to rotate, and the meshing of the drive gear 601 and the transmission gear 604 drives the support shaft 401 to rotate. The support shaft 401 then drives the winding wheel 40 to rotate, thereby winding up the flexible tubing 30. As the flexible tubing 30 is wound up, it enters the blood pressure monitor body 10 and wraps around the circumferential side wall of the winding wheel 40, thus achieving the winding of the flexible tubing 30. With proper protection, when the flexible tubing 30 brings the measuring cuff 20 to the blood pressure monitor body 10, the pressure block 201 on the side wall of the measuring cuff 20 acts on the pressure push rod 501, causing the pressure push rod 501 to move inward into the blood pressure monitor body 10. The pressure push rod 501 drives the support 502 and the push block 504 to approach the winding wheel 40. The inclined surface at one end of the push block 504 acts on the annular push plate 505, causing the annular push plate 505 to move axially along the winding wheel 40, thereby pushing the circumference of the winding wheel 40... The flexible air tube 30 on the side wall is pushed away from the end of the winding wheel 40, thereby releasing the winding state of the flexible air tube 30. In this way, when blood pressure needs to be measured again, the staff can pull the measuring cuff 20, which will move the flexible air tube 30 to the outside of the blood pressure monitor body 10. At this time, since the flexible air tube 30 is in a loose and stress-free state inside the blood pressure monitor body 10, it can effectively avoid the flexible air tube 30 being subjected to large tensile forces and thus breakage and damage, thereby achieving protection of the flexible air tube 30.

[0064] In this embodiment of the invention, when using the blood pressure monitor, the operator wraps the measuring cuff 20 around the user's arm. Then, the inflation assembly 70 supplies air into the flexible tubing 30. The air enters the air bladder inside the measuring cuff 20 through the flexible tubing 30, causing the bladder to inflate and thus block the blood vessels in the user's arm to measure blood pressure. After the blood pressure measurement is completed, the drive assembly 60 drives the winding wheel 40 to rotate. As the winding wheel 40 rotates, it winds up the flexible tubing 30, drawing it inside the blood pressure monitor body 10 and wrapping it around the winding wheel 40. This achieves the storage and protection of the flexible tubing 30, preventing it from being exposed for extended periods, reducing the probability of accidental damage, and extending its service life. After the flexible tubing 30 is wrapped around the winding wheel 40, the push assembly... The component 50 pushes the flexible tubing 30, removing it from the outside of the reel 40. When the blood pressure monitor needs to be used later, the operator only needs to pull the measuring cuff 20, which moves the flexible tubing 30 outwards from the monitor body 10. Since the flexible tubing 30 is no longer wound around the reel 40, its movement is not restricted by the reel 40. The operator only needs to exert a small pulling force to pull the flexible tubing 30 out of the monitor body 10, effectively preventing it from being subjected to excessive tension and breaking. Compared to existing technologies, this method achieves the storage and protection of the flexible tubing 30, preventing it from being exposed for extended periods, avoiding accidental damage, and extending its service life.

[0065] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the present invention, and no reference numerals in the claims should be construed as limiting the scope of the claims.

[0066] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity, and those skilled in the art should consider the specification as a whole.
