Abstract
Description
Technical Field
[0001] This utility model relates to the field of medical devices, specifically to an electrode sheet and lead wire anti-detachment connection structure. Background Technology
[0002] Existing clip-on leads connect electrode pads using a design similar to a clip. The clamping force provided by the clips fixes the relative position of the leads to the electrode pads and their conductors. However, when the electrode pads actually come into contact with the patient, the patient's subconscious movements can cause the clips to loosen from the electrode pads and their conductors. This loosening can easily lead to the separation of the clips from the electrode pads and their conductors, resulting in inaccurate detection of the patient's vital signs and misjudgment of the patient's physical or mental state. Therefore, there is an urgent need to solve the problem of easy detachment of clip-on leads from the electrode pads and their connected conductors. Utility Model Content
[0003] The purpose of this invention is to provide an electrode sheet and lead wire anti-detachment connection structure that can solve the problems existing in the prior art.
[0004] To solve the above technical problems, the present invention adopts the following technical solution: an electrode sheet and lead wire anti-detachment connection structure, including a lead block, one end of the lead block is provided with a lead clamp, and the other end is provided with a lead wire. The lead clamp includes two handles and two clips. One end of each of the two handles extends and is connected to a clip. The two clips are pivotally hinged through a pivot block. The two clips together clamp the side of a metal button. One end of the metal button is connected to an electrode sheet, and the other end of the metal button is connected to a blind hole limiting cover. The two clips are respectively provided with a first slide rail on the side away from the metal button. One end of a control strip is slidably connected to each first slide rail. The two first slide rails are connected to two joint blocks. The two ends of the joint blocks are slidably connected to one of the first slide rails.
[0005] The metal button is coaxially connected to a through-hole limiting cover and a blind-hole limiting cover. The through-hole limiting cover and the blind-hole limiting cover are symmetrically arranged with the guide clamp as the center. Each of the through-hole limiting cover and the blind-hole limiting cover is coaxially provided with a partition ring. The two partition rings are respectively arranged on the opposite sides of the through-hole limiting cover and the blind-hole limiting cover.
[0006] The combined block includes four support rods and four clamping plates. Each first slide rail is slidably connected to two support rods. The top and bottom ends of the guide clamp are respectively provided with two clamping plates. Each pair of clamping plates is symmetrically arranged with a through hole limiting cover or a blind hole limiting cover as the center. Each clamping plate is connected to one end of two support rods at both ends. The two support rods connected to the clamping plates are respectively located at different first slide rails.
[0007] Optionally, the opposing surfaces of the two clips are each connected to an arc tooth, and both arc teeth are in contact with the outer surface of the metal button.
[0008] Optionally, two positioning blocks are provided between the through hole limiting cover and the blind hole limiting cover. Each positioning block includes a connecting tube and several spacer blocks. One end of the connecting tube passes through the through hole limiting cover and extends to the outside, while the other end of the connecting tube passes through the blind hole limiting cover and extends to the outside. Several spacer blocks are coaxially provided at both ends of the connecting tube, and each spacer block is located on the side of the through hole limiting cover or the blind hole limiting cover away from the partition ring.
[0009] Optionally, each of the two clamps is provided with a second slide rail on the side away from the other clamp, and the two second slide rails are respectively connected to the other end of a control bar.
[0010] Optionally, an adjustment block is provided on one side of the pivot block. The pivot block is connected to two control bars. The adjustment block includes two connecting rods, two threaded rods, a limiting block, and a threaded sleeve. The limiting block is connected to one side of the pivot block. The threaded sleeve is coaxially sleeved on the limiting block. The threaded sleeve is movably connected to the limiting block. The two ends of the threaded sleeve are coaxially sleeved on one end of two threaded rods. The two threaded rods synchronously contract and extend relative to the threaded sleeve. One end of a connecting rod is connected to the outer side of each threaded rod. The other end of the connecting rod is connected to the outer side of the control bar. The threaded sleeve controls the distance between the threaded rod and the threaded sleeve by rotation, thereby controlling the distance between the control bar and the axis of the pivot block.
[0011] Optionally, the outer side of the limiting block is provided with an adjustment notch, and the outer side of the threaded sleeve contacts the outside through the adjustment notch.
[0012] Optionally, the control bar is circular.
[0013] Beneficial effects: The through-hole limiting cover, blind hole limiting cover, support rod, and clamping plate of this utility model work together. By utilizing the sliding of the support rod at the first slide rail, the clamping plate assists in making circumferential contact with the partition connecting the through-hole limiting cover and the blind hole limiting cover, thereby determining the distance between the through-hole limiting cover and the blind hole limiting cover, and determining the minimum distance between the through-hole limiting cover and the blind hole limiting cover. The spacer block located on one side of the through-hole limiting cover can prevent the through-hole limiting cover from detaching from the metal button, and the spacer block located on the side of the blind hole limiting cover can prevent the blind hole limiting cover from displacing towards the electrode plate, thereby preventing the metal button from detaching from the lead clamp along the direction of the metal button axis. By rotating the threaded sleeve, the distance between the two threaded rods is controlled, and then the distance between the two control bars and the axis of the pivot block is controlled by the two connecting rods, thereby controlling the distance between the two clamping plates, and thus preventing the lead clamp from separating from the metal button due to the opening and closing of the clamping plates.

[0018] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.
[0019] like Figure 1 and Figure 3As shown, an anti-detachment connection structure between an electrode pad 16 and a lead wire 12 includes a lead block 1. One end of the lead block 1 is provided with a lead clamp 11, and the other end is provided with a lead wire 12. The lead clamp 11 includes two handles 13 and two clips 14. One end of each handle 13 extends and is connected to a clip 14. The two clips 14 are pivotally hinged via a pivot block 15. The two clips 14 together clamp the side of a metal button 17. The opposite surfaces of the two clips 14 are each connected to an arc-shaped tooth 18. Both arc-shaped teeth 18 are in contact with the outer surface of the metal button 17. One end face of the metal button 17 is connected to an electrode plate 16. The metal button 17 is a cylindrical metal component responsible for transmitting the signal sensed by the electrode plate 16 to the contacted arc tooth 18, and then to the lead wire 12. The other end face of the metal button 17 is connected to a blind hole limiting cover 31. Two clips 14 are respectively provided with a first slide rail 141 on the side away from the metal button 17. Each first slide rail 141 is slidably connected to one end of a circular control strip 51. The two first slide rails 141 are connected to two joint blocks 2. The two ends of the joint blocks 2 are slidably connected to one of the first slide rails 141.
[0020] The metal button 17 is coaxially connected to a through-hole limiting cover 3 and a blind hole limiting cover 31. The through-hole limiting cover 3 and the blind hole limiting cover 31 are symmetrically arranged with the lead clamp 11 as the center. Each of the through-hole limiting cover 3 and the blind hole limiting cover 31 is coaxially provided with a partition ring 32. The two partition rings 32 are respectively arranged on the opposite surfaces of the through-hole limiting cover 3 and the blind hole limiting cover 31. The partition rings 32 can reduce the contact area between the through-hole limiting cover 3 and the blind hole limiting cover 31 and the lead clamp 11, thereby reducing the probability of the lead clamp 11 separating from the metal button 17 due to accidental contact with the through-hole limiting cover 3 and the blind hole limiting cover 31.
[0021] The connecting block 2 includes four support rods 21 and four clamping pieces 22. Each first slide rail 141 is slidably connected to two support rods 21. The top and bottom ends of the guide clamp 11 are respectively provided with two clamping pieces 22. Each pair of clamping pieces 22 is symmetrically arranged with the through hole limiting cover 3 or the blind hole limiting cover 31 as the center. Each clamping piece 22 is connected to one end of two support rods 21 at both ends. The two support rods 21 connected to the clamping piece 22 are respectively set at different first slide rails 141.
[0022] After the position of the clamping piece 22 is determined, the clamping piece 22 can prevent the lead clamp 11 from disengaging from the metal button 17 due to the metal button 17 moving toward or away from the hub block 15.
[0023] Two positioning line blocks 4 are provided between the through hole limiting cover 3 and the blind hole limiting cover 31. The positioning line block 4 includes a connecting pipe 41 and several spacer blocks 42. One end of the connecting pipe 41 passes through the through hole limiting cover 3 and leads out to the outside. The other end of the connecting pipe 41 passes through the blind hole limiting cover 31 and leads out to the outside. Several spacer blocks 42 are coaxially provided at both ends of the connecting pipe 41. Each spacer block 42 is provided on the side of the through hole limiting cover 3 or the blind hole limiting cover 31 away from the partition ring 32.
[0024] Each of the two clamps 13 has a second slide rail 131 on the side away from the other clamp 13, and the two second slide rails 131 are respectively connected to the other end of a control bar 51.
[0025] A positioning block 5 is provided on one side of the pivot block 15. The pivot block 15 is connected to two control bars 51. The positioning block 5 includes two connecting rods 52, two threaded rods 53, a limiting block 55, and a threaded sleeve 54. The limiting block 55 is connected to one side of the pivot block 15. The threaded sleeve 54 is coaxially sleeved on the limiting block 55. The threaded sleeve 54 is movably connected to the limiting block 55. An adjustment notch 56 is provided on the outer surface of the limiting block 55. The outer surface of the threaded sleeve 54 contacts the outside through the adjustment notch 56. The two ends of the threaded sleeve 54 are coaxially sleeved on one end of two threaded rods 53. The two threaded rods 53 are synchronously relative to the threaded rods. The sleeve 54 contracts and extends. Each threaded rod 53 has a connecting rod 52 connected to one end of its outer side. The other end of the connecting rod 52 is connected to the outer side of the control bar 51. The threaded sleeve 54 controls the distance between the threaded rod 53 and the threaded sleeve 54 by rotation, thereby controlling the distance between the control bar 51 and the axis of the pivot block 15. The adjustment block 5 controls the distance between the opposite surfaces of the two clamping pieces 14 by the rotation of the threaded sleeve 54. This effectively avoids the clamping pieces 14 from separating from the metal button 17 due to accidental contact with the two clamping handles 13, and effectively reduces the potential risk of the lead clamp 11 and the metal button 17 separating.
[0026] The specific implementation method of this application is as follows: The through-hole limiting cover 3 and the blind hole limiting cover 31 are coaxially connected to the metal button 17. Two clamping pieces 14 are positioned between the through-hole limiting cover 3 and the blind hole limiting cover 31. The spacers 42 at both ends of the connecting conduit 41 are brought closer together until they contact the through-hole limiting cover 3 and the blind hole limiting cover 31 respectively, thus limiting the through-hole limiting cover 3 and the blind hole limiting cover 31. This prevents the through-hole limiting cover 3 from detaching from the metal button 17 and also prevents the blind hole limiting cover 31 from moving towards the electrode plate 16, thereby preventing the lead clamp 11 from detaching from the metal button 17 along its axis. The connection between the control strip 51 and the adjusting block 5, and the limiting block 55 connected to the pivot block 15, are movably connected to the threaded sleeve 54. Rotation of the threaded sleeve 54 in different directions causes the threaded rods 53 at both ends of the threaded sleeve 54 to move closer and further apart, thereby driving the two control strips 51 to move closer and further apart. The positioning strips 51 move closer to and further away from the axis of the pivot block 15. When the two positioning strips 51 are far from the axis of the pivot block 15, the distance between the first slide rail 141 and the second slide rail 131 connected to both ends of the positioning strips 51 will be shortened, thereby controlling the opposing surfaces of the two clamping pieces 14 to move away from each other. When the two positioning strips 51 are close to the axis of the pivot block 15, the distance between the first slide rail 141 and the second slide rail 131 connected to both ends of the positioning strips 51 will be increased, thereby making the opposing surfaces of the two clamping pieces 14 close to each other. Therefore, by using the threaded sleeve 54, the threaded rod 53 and the positioning strips 51 to achieve the contact between the lead clamp 11 and the metal button 17, it is possible to avoid the separation of the lead clamp 11 and the metal button 17 caused by the moving away of the opposing surfaces of the two clamping pieces 14 due to other factors. This avoids the connection between the electrode piece 16 and the lead wire 12 from being interrupted due to physical detachment during use, and can effectively improve the stability of the connection.
