Description

Technical Field

[0001] This utility model relates to the field of blood pressure monitor technology, and in particular to blood pressure monitors. Background Technology

[0002] The ankle-brachial index (ANCI) is a test method that assesses the blood flow status of the lower limb arteries by measuring the ratio between the systolic blood pressure of the ankle artery and the systolic blood pressure of the brachial artery. It uses an electronic blood pressure monitor to measure blood pressure in the upper and lower limbs separately using the Korotkoff sound method, and calculates the blood pressure ratio between the upper and lower limbs after the measurement is completed.

[0003] A blood pressure monitor typically consists of a cuff, a connecting cable, and a controller. To use the monitor, the cuff is strapped above the ankle, and then the monitor is turned on and the measurement is awaited. When carrying the monitor after use, the connecting cable is long and difficult to store, and it is easy for the cable to fall to the ground during handling. Accidental stepping on the cable may cause the connection between the cable and the cuff and controller to break or loosen, affecting the normal use of the blood pressure monitor. Utility Model Content

[0004] The purpose of this invention is to solve the problems of the blood pressure monitor for lower limb blood pressure measurement, which is proposed because the connecting wire is too long to store and is easy to fall to the ground during handling. Accidental stepping on it may cause the connection between the connecting wire and the cuff and controller to break or loosen, affecting the normal use of the blood pressure monitor.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a blood pressure monitor, comprising a body, a connecting wire fixedly connected to one side of the body, a strap fixedly connected to the end of the connecting wire away from the body, Velcro fasteners at both ends of the strap, a display screen on one side of the body, several control buttons on the outer surface of the body near the display screen, and a convenient device for storing the connecting wire at the top of the body.

[0006] The aforementioned components achieve the following effects: When using a blood pressure monitor to measure blood pressure in the lower limbs, the person being measured lies flat on the bed, the strap is tied above the ankle joint on the lower leg, and the strap is fastened with Velcro at both ends. Press the control button on one side of the device to start the device and keep the environment quiet. The blood pressure is determined by the sound produced by the pressure change of the arterial blood vessels inside the strap through the sensor inside the strap, and the data is displayed on the screen. After the blood pressure monitor is used, the connecting cable is stored in a convenient device for easy carrying of the blood pressure monitor.

[0007] Preferably, the convenient device includes a baffle, a bent rod fixedly connected to the bottom end of the baffle, two springs provided on one side of the bent rod, slots respectively opened at the upper and lower ends of the device body, a rectangular groove opened on one side of the inner wall of one of the slots, the outer surface of the baffle sliding on the inner wall of the rectangular groove, two sliding grooves opened on one side of the device body, the outer surface of the bent rod sliding on the inner wall of the sliding groove, and the two ends of the two springs fixedly connected to one side of the bent rod and one side of the inner wall of the device body respectively.

[0008] The effect achieved by the above components is as follows: By setting up the baffle, after the blood pressure monitor is used, the connecting wire can be wound inside the two slots at the top and bottom of the device. When the connecting wire contacts the top of the baffle located inside the top slot of the device, it will push the baffle to slide outward on the inner wall of the rectangular slot, and drive the bending rod to slide on the inner wall of the slide groove, compressing the two springs. After the connecting wire enters the slot, the spring returns to its original shape, which will push the bending rod and the baffle to move, so that the baffle returns to its original position and closes the top of the inner wall of the slot, thus restricting the position of the connecting wire inside the slot. Then, the strap is put on the outer surface of the device and the two ends are glued with Velcro to store the connecting wire on the outer surface of the device. This minimizes the inconvenience caused by the connecting wire falling out when carrying and storing the device, and improves the convenience of using the blood pressure monitor.

[0009] Preferably, an auxiliary rod is fixedly connected to one end of the baffle, and the top edge of the auxiliary rod is arc-shaped.

[0010] The effect achieved by the above components is that when the connecting wire is inserted into the slot, it is easier to push the baffle to move when the connecting wire contacts the arc-shaped edge at the top of the auxiliary rod.

[0011] Preferably, a magnetic rod is fixedly connected to one side of the bottom end of the baffle, and a magnetic sheet is fixedly connected to the outer surface of the device near the rectangular groove, wherein the magnetic rod and the magnetic sheet have different magnetic properties.

[0012] The effect achieved by the above components is that when the baffle is inside the slot, one end of the magnetic rod will contact the magnetic sheet surface on the outer surface of the device and be attracted by magnetism, which further restricts the position of the baffle inside the slot and avoids the baffle from moving accidentally as much as possible.

[0013] Preferably, two round rods are fixedly connected to the inner wall of the device, and the bent rod slides on the outer surface of the round rods.

[0014] The effect achieved by the above components is that when the baffle and the bending rod move, the bending rod will slide on the outer surface of the two round rods. The round rods can further limit the angle between the bending rod and the baffle and the body, and minimize the deviation of the angle of the baffle and the bending rod.

[0015] Preferably, the two springs are located on the outer sides of the two round rods, and the inner diameter of the springs is slightly larger than the diameter of the round rods.

[0016] The effect achieved by the above components is that when the bending rod moves and causes the spring to deform, the spring will move on the outside of the round rod. The round rod can reinforce the internal shape of the spring and prevent the spring from twisting laterally as much as possible.

[0017] Preferably, a protective device is provided on the outer surface of the device body near the connecting line. The protective device includes a threaded tube, one end of which is fixedly connected to one side of the device body. A threaded cylinder is threadedly connected to the outer surface of the threaded tube, and a rubber gasket is fixedly connected to one end of the inner wall of the threaded cylinder.

[0018] The effect achieved by the above components is as follows: when the connecting wire is wound onto the outer surface of the device with the help of the convenient device, rotating the threaded cylinder can control the movement of the threaded cylinder on the outer surface of the threaded tube to adjust the position of the threaded cylinder. When the end of the connecting wire close to the device body is bent, it will contact the rubber gasket ring at one end of the inner wall of the threaded cylinder. The threaded cylinder and the threaded tube protect the outer side of the connecting wire close to the device body, and minimize the risk of large-angle deflection and breakage at the connection between the connecting wire and the device body when winding the connecting wire.

[0019] Preferably, a plurality of protrusions are fixedly connected to the outer surface of the threaded cylinder, and the protrusions are distributed circumferentially on the outer surface of the threaded cylinder.

[0020] The effect achieved by the above components is that by pressing the protrusion on the outer surface of the threaded cylinder with your hand, you can more easily push the threaded cylinder to rotate and adjust its position.

[0021] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0022] In this invention, a convenient device is provided. The connecting wire is wound around the two slots at the top and bottom of the device body, and the position of the connecting wire inside the slots is restricted by the baffle. The connecting wire can be stored on the outer surface of the device body by putting the strap on the outer surface of the device body and gluing the two ends with Velcro. This minimizes the inconvenience caused by the connecting wire falling out when carrying and storing the device body, and improves the convenience of using the blood pressure timer.

Detailed Implementation

[0030] Example 1, such as Figure 1-2 As shown, a blood pressure monitor for lower limb blood pressure measurement includes a body 1. A connecting cable 6 is fixedly connected to one side of the body 1. A strap 7 is fixedly connected to the end of the connecting cable 6 away from the body 1. Velcro is provided at both ends of the strap 7. A display screen 4 is provided on one side of the body 1. Several control buttons 5 are provided on the outer surface of the body 1 near the display screen 4. A convenient device 2 for storing the connecting cable 6 is provided at the top of the body 1. When using the blood pressure monitor to measure blood pressure in the lower limbs, the subject lies flat on the bed, and the strap 7 is tied above the ankle joint on the lower leg. The strap 7 is fastened by the Velcro at both ends. Pressing the control button 5 on one side of the body 1 starts the body 1. Keep the environment quiet. The blood pressure is determined by the sound produced by the pressure change of the arterial blood vessels in the strap 7 by the sensor inside the strap 7. The data is displayed on the display screen 4. After the blood pressure monitor is used, the connecting cable 6 is stored in the convenient device 2 for easy carrying of the blood pressure monitor.

[0031] Reference Figure 1-6As shown in this embodiment: the convenient device 2 includes a baffle 24, with a bent rod 25 fixedly connected to the bottom end of the baffle 24. Two springs 26 are provided on one side of the bent rod 25. Slots 21 are respectively provided at the upper and lower ends of the device body 1. A rectangular groove 23 is provided on one side of the inner wall of one slot 21. The outer surface of the baffle 24 slides on the inner wall of the rectangular groove 23. Two sliding grooves 22 are provided on one side of the device body 1, and the outer surface of the bent rod 25 slides on the inner wall of the sliding groove 22. The two ends of the two springs 26 are fixedly connected to one side of the bent rod 25 and one side of the inner wall of the device body 1, respectively. By setting the baffle 24, after the blood pressure monitor is used, the connecting wire 6 can be wound around the two slots 21 at the upper and lower ends of the device body 1 to connect... When the wire 6 contacts the top of the baffle 24 inside the slot 21 at the top of the device 1, it pushes the baffle 24 to slide outward on the inner wall of the rectangular slot 23 and causes the bent rod 25 to slide on the inner wall of the slide groove 22, compressing the two springs 26. After the wire 6 enters the slot 21, the springs 26 return to their original shape, which pushes the bent rod 25 and the baffle 24 to move, so that the baffle 24 returns to its original position and closes the top of the inner wall of the slot 21, thus restricting the position of the wire 6 inside the slot 21. Then, the strap 7 is put on the outer surface of the device 1 and the two ends are glued with Velcro to store the wire 6 on the outer surface of the device 1, so as to avoid the inconvenience caused by the wire 6 falling off when carrying and storing the device 1, and improve the convenience of using the blood pressure timer.

[0032] Reference Figure 2-6 As shown in this embodiment: one end of the baffle 24 is fixedly connected to an auxiliary rod 27. The top edge of the auxiliary rod 27 is arc-shaped. When the connecting wire 6 is inserted into the slot 21, it is easier to push the baffle 24 to move when the connecting wire 6 contacts the arc-shaped edge of the top of the auxiliary rod 27. A magnetic rod 28 is fixedly connected to one side of the bottom end of the baffle 24. A magnetic sheet 29 is fixedly connected to the side of the outer surface of the device 1 near the rectangular groove 23. The magnetic rod 28 and the magnetic sheet 29 have different magnetic properties. When the baffle 24 is located inside the slot 21, one end of the magnetic rod 28 will contact the surface of the magnetic sheet 29 on the outer surface of the device 1 and be attracted by magnetism. This further restricts the position of the baffle 24 inside the slot 21 and avoids the baffle 24 from moving accidentally as much as possible.

[0033] Reference Figure 2-6As shown in this embodiment: two round rods 210 are fixedly connected to the inner wall of the device 1. A bent rod 25 slides on the outer surface of the round rods 210. When the baffle 24 and the bent rod 25 move, the bent rod 25 will slide on the outer surface of the two round rods 210. The round rods 210 can further limit the angle between the bent rod 25 and the baffle 24 and the device 1, so as to avoid the angle of the baffle 24 and the bent rod 25 from deflecting as much as possible. Two springs 26 are located on the outer side of the two round rods 210 respectively. The inner diameter of the spring 26 is slightly larger than the diameter of the round rod 210. When the bent rod 25 moves and causes the spring 26 to deform, the spring 26 will move on the outer side of the round rod 210. The round rods 210 can reinforce the internal shape of the spring 26, so as to avoid the spring 26 from twisting laterally as much as possible.

[0034] Reference Figure 1-2 As shown in this embodiment: a protective device 3 is provided on the outer surface of the device body 1 near the connecting line 6. The protective device 3 includes a threaded tube 31, one end of which is fixedly connected to one side of the device body 1. A threaded cylinder 32 is threadedly connected to the outer surface of the threaded tube 31, and a rubber gasket 33 is fixedly connected to one end of the inner wall of the threaded cylinder 32. When the connecting line 6 is wound up on the outer surface of the device body 1 with the help of the convenient device 2, rotating the threaded cylinder 32 can control the movement of the threaded cylinder 32 on the outer surface of the threaded tube 31 to adjust the position of the threaded cylinder 32. The connecting line 6 is closer to the outer surface of the device body 1. When the end is bent, it will contact the rubber gasket 33 at one end of the inner wall of the threaded cylinder 32. The threaded cylinder 32 and the threaded tube 31 protect the outside of the connecting line 6 near the body 1, so as to avoid large-angle deflection and breakage at the connection between the connecting line 6 and the body 1 when winding the connecting line 6. Several protrusions 34 are fixedly connected to the outer surface of the threaded cylinder 32. The protrusions 34 are distributed in a circle on the outer surface of the threaded cylinder 32. By pressing the protrusions 34 on the outer surface of the threaded cylinder 32 with your hand, you can more easily push the threaded cylinder 32 to rotate and adjust its position.

[0035] Working principle: When measuring blood pressure in the lower limbs using a blood pressure monitor, the subject lies flat on the bed, and the strap 7 is tied above the ankle on the lower leg. The strap 7 is secured with Velcro at both ends. The device is activated by pressing the control button 5 on one side of the device body 1, and the environment is kept quiet. The sensor inside the strap 7 detects the sound produced by the pressure changes in the arterial blood vessels within the strap 7 to determine the blood pressure, which is then displayed on the screen 4. After use, the threaded cylinder 32 is rotated on one side of the device body 1 to adjust its position by moving it along the outer surface of the threaded tube 31. The connecting wire 6 is pulled and wound around the two slots 21 at the top and bottom of the device body 1. When the connecting wire 6 contacts the top of the baffle 24 located inside the top slot 21 of the device body 1, it pushes the baffle 24 into the rectangular groove 23. The wall slides outward, causing the bending rod 25 to slide and compress the two springs 26 on the inner wall of the groove 22. After the connecting wire 6 enters the slot 21, the springs 26 return to their original state, which will push the bending rod 25 and the baffle 24 to move, so that the baffle 24 returns to its original position and seals the top of the inner wall of the slot 21, thus restricting the position of the connecting wire 6 inside the slot 21. Then, the strap 7 is put on the outer surface of the device 1 and the two ends are glued together with Velcro to store the connecting wire 6 on the outer surface of the device 1. When the end of the connecting wire 6 near the device 1 is bent, it will contact the rubber gasket 33 at one end of the inner wall of the threaded cylinder 32. The threaded cylinder 32 and the threaded tube 31 protect the outside of the connecting wire 6 near the device 1, so as to avoid a large angle of deflection and breakage at the connection between the connecting wire 6 and the device 1 when winding the connecting wire 6.
