Description

Technical Field

[0001] The present invention relates to the field of cardiac pacemaker post-operative protection, in particular to a cardiac pacemaker post-implantation displacement prevention device. Background Art

[0002] Currently, after permanent pacemaker implantation surgery, the patient is required to lie flat, cover the incision with a sterile dressing and apply pressure with a sandbag or commercially available salt bag for 4-6 hours, and require the patient to stay in bed for 3-7 days. The limb on the operated side must be absolutely immobilized. After 24 hours, the patient can lie on the left side at 30 degrees, and can move slightly after 3 days. However, the upper limb on the operated side must be restricted in activity within 7 days to prevent capsular bleeding or blood accumulation and electrode dislocation.

[0003] Since the sandbags or salt bags currently used for compression hemostasis are only placed flat on the incision and pressed with the help of family members, even if the initial pressure site is correct, the pressure bag may still shift if not paid attention to during the pressure process, and the family members cannot discover the subtle displacement in time. Once the pressure bag shifts, blood accumulation is likely to form a sac. Secondly, the compression time is too long, and it is difficult for family members to maintain a certain pressure continuously. The uneven pressure force is not conducive to the patient's postoperative recovery. Summary of the invention

DETAILED DESCRIPTION

[0025] The technical solution of the present invention is further described in detail below in conjunction with the accompanying drawings, but the protection scope of the present invention is not limited to the following.

[0026] Embodiment 1

[0027] like Figures 1 to 6As shown, a post-implantation displacement prevention device for cardiac pacemaker comprises a compression vest 1, on which an adjustable compression mechanism is arranged, the adjustable compression mechanism comprises an adhesive cloth 2, an air pressure bag 3 and a zipper tape 4, the adhesive cloth 2 is adhered to the compression vest 1, two zipper tapes 4 are fixed on the adhesive cloth 2 at intervals in the horizontal direction, a zipper 6 is arranged on the zipper tape 4, the air pressure bag 3 is located between the two zipper tapes 4, the four corners of the air pressure bag 3 are connected to zipper buckles 5, and the zipper buckles 5 are slidably adapted on the nearest zipper 6; a heavy object compression body is arranged in the air pressure bag 3, and the heavy object compression body is pressed tightly at the patient's pacemaker implantation position through a strap assembly A pressure cavity 7 is formed between the inner wall and the outer wall of the pressure bag 3, and a micro barometer 8 is arranged on the pressure bag 3. The detection end of the micro barometer 8 is inserted into the pressure cavity 7. The compression vest 1 is worn on the patient, and the patient's pacemaker implantation position is compressed by the heavy compression body. The displacement or falling off of the heavy compression body is prevented by wearing it, and the heavy compression body is pressed tightly to the pacemaker implantation position by the strap assembly. On the one hand, the heavy compression body is further limited to prevent displacement, and on the other hand, the compression force of the heavy compression body on the pacemaker implantation position remains unchanged, which is conducive to the rapid recovery of the patient; due to the different body shapes of different patients , so that the implantation position of the pacemaker has a large difference. In order to make the heavy object compression body accurately compress the implantation position of the pacemaker for different patients, the position of the air pressure bag 3 can be adjusted according to the implantation position of the pacemaker. By adjusting the adhesion position of the adhesive cloth 2, the position of the air pressure bag 3 is adjusted in the horizontal position. By sliding the zipper buckle 5 on the zipper 6, the position of the air pressure bag 3 in the longitudinal direction can be adjusted. The position of the air pressure bag 3 can be adjusted in two directions, so that the air pressure bag 3 can accurately compress the implantation position of the pacemaker, with a better compression effect; preferably, an inflation valve mouth is provided on the air pressure bag 3, through The inflation valve mouth inflates air into the air pressure chamber 7 to expand the air pressure bag 3, and the heavy object pressure body acts on the air pressure bag 3 to compress the implanted position of the pacemaker. On the one hand, the inflated air bag 3 is used for buffering, which can reduce the damage caused by the pressure of the heavy object pressure body. Secondly, the pressure force of the heavy object pressure body will squeeze the air pressure bag 3 to cause deformation, so that the pressure in the air pressure chamber 7 changes. The pressure condition in the air pressure chamber 7 is detected by the micro air compressor 8 to adjust the pressure of the heavy object pressure body, so that the pressure applied by the heavy object pressure body can be accurately controlled, and the pressure can be adjusted by changing the weight of the heavy object pressure body. In specific implementation, the heavy object pressure body adopts a sand bag or a salt bag.

[0028] Embodiment 2

[0029] Based on the first embodiment, Figure 1As shown, the compression vest 1 is fixed with two magic plush belts 22 at the top and bottom, and the adhesive cloth 2 is provided with a magic hook-shaped surface, which is magic-adhered to the magic plush belt 22. The two magic plush belts 22 are spaced apart from each other and have a wide adaptability, so that the implantation position of the pacemaker is located between the two magic plush belts 22. The adhesive cloth 2 is connected to the compression vest 1 by means of Velcro, and its lateral position can be adjusted according to the implantation position of the pacemaker.

[0030] Embodiment 3

[0031] Based on the second embodiment, Figure 1 and Figure 2 As shown, the strap assembly includes a transverse strap 23, one end of which is fixedly connected to one side of the compression vest 1, and a first mesh buckle 24 is fixed to the other side of the compression vest 1. The end of the transverse strap 23 away from the compression vest 1 is wound around the first mesh buckle 24. By setting the first mesh buckle 24, the tightening length of the transverse strap 23 can be controlled, so that the heavy object compression body is pressed tightly at the implantation position of the pacemaker. Similarly, the strap assembly also includes a longitudinal strap 25, one end of which is fixedly connected to the compression vest 1. 1 is provided with a second mesh buckle 26, one end of the longitudinal strap 25 away from the compression vest 1 is wound around the second mesh buckle 26, the transverse strap 23 and the longitudinal strap 25 are staggered to squeeze the air pressure bag 3, and the longitudinal strap 25 is connected with the second mesh buckle 26 to facilitate disassembly and control the tightening degree of the longitudinal strap 25, so that the longitudinal strap 25 is well squeezed on the heavy object compression body, and the heavy object compression body is limited from two directions through the cooperation of the transverse strap 23 and the longitudinal strap 25, further ensuring that the heavy object compression body will not be displaced or fall off.

[0032] Furthermore, a first annular belt 27 is fixed on the air pressure bag 3, the transverse strap 23 passes through the first annular belt 27 and is connected to the first mesh buckle 24, a second annular belt 28 is fixed on the transverse strap 23, the longitudinal strap 25 passes through the second annular belt 28 and is connected to the second mesh buckle 26, the transverse strap 23 is connected to the air pressure bag 3 through the first annular belt 27, and the transverse strap 23 is connected to the longitudinal strap 25 through the second annular belt 28, thereby strengthening the connection strength between the strap assembly and the heavy object pressure body, preventing the strap assembly from falling off the heavy object pressure body, and ensuring the stability of the compression.

[0033] Embodiment 3

[0034] Based on the second embodiment, Figure 1 , Figure 4 and Figure 5As shown, a limiting plate 9 is fixed to the side of the zipper buckle 5 away from the air pressure bag 3, and a locking mechanism is arranged on the limiting plate 9, which includes a disc 10, a locking needle 11 and a locking cylinder 12. A locking needle 11 is fixed to one end of the disc 10, and a through hole 13 is opened on the limiting plate 9. The locking needle 11 passes through the zipper tape 4 and the through hole 13 in sequence and is plugged into the locking cylinder 12. Since the zipper 6 and the zipper buckle 5 cannot complete self-locking, the heavy object pressing body can easily drive the zipper buckle 5 to slide on the zipper 6 under the gravity of the heavy object pressing body, and the effect of limiting the heavy object pressing body by the strap assembly alone is not good, which can only ensure that the heavy object pressing body does not fall off, but the heavy object pressing body will still deviate. To this end, a locking mechanism is provided to lock the zipper buckle 5, thereby locking the position of the heavy object pressure body, and then cooperating with the strap assembly to press the heavy object pressure body tightly at the implantation position of the pacemaker; the specific method of using the locking mechanism is as follows: after the longitudinal position adjustment of the air pressure bag 3 is completed, the locking needle 11 is passed upward from the bottom of the zipper tape 4, and the locking needle 11 is passed through the through hole 13 of the limiting plate 9, and then the locking cylinder 12 is sleeved on the locking needle 11, so that the locking cylinder 12 and the disc 10 are respectively in contact with the two sides of the zipper tape 4, thereby connecting the zipper tape 4 and the zipper buckle 5 together, so that it will not slide on the zipper 6, and cooperating with the action of the strap assembly to ensure that the heavy object pressure body will not be offset.

[0035] Embodiment 4

[0036] Based on the third embodiment, Figure 4 and Figure 5As shown, two arc-shaped limit blocks 14 are symmetrically fixed on the side wall of the lock needle 11, and a lock cavity 15 is arranged in the lock cylinder 12. A circular hole 16 is provided at one end of the lock cylinder 12, and the lock needle 11 is slidably adapted to the circular hole 16. Two groups of avoidance grooves 17 are provided on the inner wall of the circular hole 16. The circular hole 16 and the avoidance groove 17 are both connected to the lock cavity 15. The two groups of avoidance grooves 17 correspond to the two arc-shaped limit blocks 14 one by one. The arc-shaped limit blocks 14 slide into the lock cavity 15 through the avoidance grooves 17. The lock needle 11 is rotated to make the arc-shaped limit blocks 14 and the avoidance grooves 17 interlaced, so as to link the lock needle 11 to the lock cylinder 12. The avoidance groove 17 extends to the lock cavity 15, and the inner wall of the lock cavity 15 is provided with an arc groove 18 and a vertical slide groove 19. The arc groove 18 and the lock cylinder 12 are coaxially arranged, the avoidance groove 17 and the vertical slide groove 19 are respectively connected to the two ends of the arc groove 18, the vertical slide groove 19 extends toward the circular hole 16, and the length of the vertical slide groove 19 is less than the length of the avoidance groove 17. An abutment plate 20 is slidably arranged in the lock cavity 15, and a spring 21 is connected to the end of the abutment plate 20 away from the circular hole 16, and the spring 21 is connected to the lock cylinder 12. When the arc-shaped limit block 14 is adapted in the vertical slide groove 19, the spring 21 is in a compressed state. The lock cavity 15 is in a stepped shape, including a small diameter hole and a large diameter hole. The two ends of the small diameter hole are respectively connected to the circular hole 16 and the large diameter hole. The diameter of the small diameter hole is equal to the diameter of the circular hole 16. The abutment plate 20 is arranged in the large diameter hole, and the arc limit of the lock needle 11 The block 14 is inserted into the lock cylinder 12 corresponding to the avoidance groove 17 until the arc-shaped limit block 14 moves to the bottom position of the avoidance groove 17 and cannot move. In this process, the lock needle 11 will squeeze the abutment plate 20, so that the abutment plate 20 compresses the spring 21 to adapt to the movement, and then, the lock needle 11 is rotated to make the arc-shaped limit block 14 deflected into the vertical slide groove 19 through the arc groove 18, and then, the lock cylinder 12 is released, and the lock cylinder 12 moves under the reaction force of the spring 21, so that the arc-shaped limit block 14 abuts against one end of the vertical slide groove 19 away from the arc groove 18. Since the vertical slide groove 19 does not pass through the circular hole 16, the lock needle 11 cannot slide out of the lock cylinder 12, and then the lock cylinder 12 is connected with the lock needle 11 to realize the zipper buckle. 5 is fixed to ensure that the heavy object pressing body will not deviate; when the sliding freedom of the zipper buckle 5 needs to be unlocked, the lock cylinder 12 and the lock pin 11 are moved closer to each other, so that the arc-shaped limit block 14 is moved to one end of the vertical slide groove 19 close to the arc groove 18 until the lock pin 11 cannot be moved. At this time, the arc-shaped limit block 14 moves from the vertical Hu Chao 19 to the arc groove 18, and then the lock pin 11 or the lock cylinder 12 is reversed to rotate the arc-shaped limit block 14 to the avoidance groove 17, and finally the lock pin 11 is pulled out, and the arc-shaped limit block 14 can slide from the lock cylinder 12 through the avoidance groove 17 to complete the separation of the lock cylinder 12 and the lock pin 11. The operation is simple and convenient to use, the volume is small, and no pressure is caused to the patient.
