Abstract
Description
Technical Field
[0001] This utility model relates to the field of medical assistive devices technology, specifically to a post-pacemaker implantation restraint belt. Background Technology
[0002] Pacemaker implantation is a surgical procedure in which lead wires for a cardiac pacemaker are inserted into the heart via a vein, and the pacemaker's pulse generator is then implanted subcutaneously in the chest (e.g., ...). Figure 8 As shown in the image, a pacemaker is a technology that stimulates the heart by releasing electrical pulses, enabling the heart to contract and relax according to a normal rhythm. Under normal circumstances, the heart can rely on its own conduction system to contract and relax in an orderly manner to maintain normal blood circulation. However, when there are problems with the heart's conduction system, such as sick sinus syndrome or atrioventricular block, resulting in bradycardia or abnormal heart rhythm, a pacemaker can simulate the electrical signals of a normal heart, delivering appropriate electrical pulses to stimulate the heart, restoring the heart's normal beating frequency and rhythm, ensuring the heart pumps blood normally, and maintaining the blood supply to all organs of the body.
[0003] The first 1-3 months after pacemaker implantation are a critical period for recovery, during which careful control of movement in the operated arm is essential. Figure 9 As shown, if the arm is raised high or moves significantly during this period, the pulse transmitter and wires that are not yet firmly anchored in the body may be subjected to abnormal external forces, resulting in traction, twisting, etc., increasing the risk of electrode dislocation.
[0004] Chinese patent document CN221154459U discloses a post-pacemaker implantation restraint band. The post-pacemaker restraint band includes a first restraint band, with a first hook and loop fastener fixedly connected to one end of the outer side and the other end of the inner side of the first restraint band, respectively. A second hook and loop fastener is fixedly connected to the upper end of the outer side of the first restraint band near the hook and loop fastener. A second restraint band is fixedly connected to the top of the first restraint band. A second hook and loop fastener is fixedly connected to the lower end of the outer side of the second restraint band. Hooks and loops are symmetrically fixedly connected to one end of the outer side of the first restraint band near the hook and loop fastener. A tether is symmetrically fixedly connected to the other end of the outer side of the first restraint band. A connecting band is provided at the other end of the outer side of the first restraint band. A third restraint band is provided outside the connecting band. A third hook and loop fastener is fixedly connected to one end of the outer side and the other end of the inner side of the third restraint band, respectively. The method of using the technical solution in the aforementioned patent literature is as follows: A first restraint strap, a second restraint strap, and a third restraint strap are wrapped around the patient's body, shoulders, and left arm. The first restraint strap, with its first Velcro loop and hook surface at both ends, allows for adjustment based on the patient's body type. The second restraint strap, with its second Velcro loop and hook surface, allows for adjustment of the wrapping position at different shoulder heights. The third restraint strap, with its third Velcro loop and hook surface at both ends, allows for adjustment of the wrapping position for different arm thicknesses. A connecting strap located between the first and third restraint straps restricts the range of motion of the patient's outrigger arm to prevent excessive swinging, which could lead to pain, shoulder stiffness, etc. The problem with this technical solution is that when the restraint straps are fixed to the patient's corresponding areas for extended periods after surgery, the local skin is subjected to prolonged pressure, which can easily cause discomfort, thereby reducing patient compliance with the treatment plan and affecting the overall treatment effect and patient satisfaction.
[0005] Therefore, how to design a post-pacemaker implantation restraint strap that can limit the large-scale movement of the operated arm and reduce discomfort caused by prolonged pressure on the skin is a technical problem that has not yet been solved in the existing technology.

[0010] As a preferred embodiment, the chest restraint strap and the upper arm restraint strap are fixedly connected by a first limiting strap, which can limit the distance between the upper arm restraint strap and the chest restraint strap, thereby restricting the range of motion of the patient's upper arm.
[0011] As a preferred embodiment, a hook-and-loop fastener is fixedly provided on the inner side of one end of the chest restraint strap, and a loose hook-and-loop fastener is fixedly provided on the outer side of the other end, opposite to the hook-and-loop fastener; the hook-and-loop fastener can be opened and closed and adhered to the loose hook-and-loop fastener, thereby enabling the chest restraint strap to be tightened and fixed.
[0012] As a preferred embodiment, an upper arm hook-and-loop fastener is fixedly provided on the inner side of one end of the upper arm restraint strap, and an upper arm loop fastener is fixedly provided on the outer side of the other end, opposite to the upper arm hook-and-loop fastener; the upper arm hook-and-loop fastener can be opened and closed and adhered to the upper arm loop fastener, thereby enabling the upper arm restraint strap to be tightened and fixed.
[0013] As a preferred embodiment, the abdominal restraint strap and the forearm restraint strap are fixedly connected by a second limiting strap, which can limit the distance between the forearm restraint strap and the abdominal restraint strap, thereby restricting the range of motion of the patient's forearm.
[0014] As a preferred embodiment, an abdominal hook-and-loop fastener is fixedly provided on the inner side of one end of the abdominal restraint strap, and an abdominal loop fastener is fixedly provided on the outer side of the other end, opposite to the abdominal hook-and-loop fastener; the abdominal hook-and-loop fastener can be opened and closed and adhered to the abdominal loop fastener, thereby enabling the abdominal restraint strap to be tightened and fixed.

[0034] The present application will now be described in detail with reference to the accompanying drawings and embodiments. Example
[0035] This embodiment provides a post-pacemaker implantation restraint belt, such as... Figure 1-2As shown, it includes: a chest restraint strap 11, an upper arm restraint strap 13, a connecting strap 3, an abdominal restraint strap 21, and a forearm restraint strap 23; wherein the chest restraint strap 11 is adapted to be detachably wrapped and fixed to the patient's chest; the upper arm restraint strap 13 is fixedly connected to one side of the chest restraint strap 11, and is arranged opposite to the chest restraint strap 11 on the left and right, adapted to be detachably fixed to the patient's upper arm; one end of the connecting strap 3 is fixedly connected to the bottom of the chest restraint strap 11; the top of the abdominal restraint strap 21 is fixedly connected to the other end of the connecting strap 3, and is arranged opposite to the chest restraint strap 11 on the top and bottom, adapted to be detachably wrapped and fixed to the patient's abdomen; the forearm restraint strap 23 is fixedly connected to one side of the abdominal restraint strap 21, and is arranged opposite to the abdominal restraint strap 21 on the left and right, adapted to be detachably fixed to the patient's forearm.
[0036] When using the pacemaker implantation post-operative restraint band of this embodiment, firstly, wrap and fix the chest restraint band 11 around the patient's chest, and then fix the upper arm restraint band 13 around the patient's upper arm. This completes the restraint of the patient's operated arm. During the wearing process, if the patient feels discomfort in the chest or upper arm, first wrap and fix the abdominal restraint band 21 around the patient's abdomen, and then fix the forearm restraint band 23 around the patient's forearm. After that, remove the chest restraint band 11 and the upper arm restraint band 13, which can also achieve restraint of the patient's operated arm. If the patient then feels discomfort in the abdomen and forearm, after fixing the chest restraint band 11 and the upper arm restraint band 13 in place, remove the abdominal restraint band 21 and the forearm restraint band 23, and repeat this cycle. The pacemaker implantation post-operative restraint band of this embodiment can flexibly adjust the fixation position, avoid continuous pressure on a single area, reduce discomfort caused by pressure, optimize the patient's treatment experience, and improve patient satisfaction.
[0037] It also includes a shoulder fixation structure 4, which is used to limit and fix the chest restraint strap 11 to the patient's chest.
[0038] The shoulder fixation structure 4 includes a diagonal strap 5, a fixing buckle 6, and a fixing buckle 7. One end of the diagonal strap 5 is fixedly connected to one side of the chest restraint strap 11, and the other end extends outward and can be wrapped around and fixed to the other side of the chest restraint strap 11. The fixing buckle 6 is fixedly disposed on the other end of the diagonal strap 5. Several fixing buckles 7 are fixedly disposed on the other side of the chest restraint strap 11. The fixing buckle 6 can be matched and installed with the fixing buckle 7, thereby limiting the diagonal strap 5 to the patient's shoulder. After the chest restraint strap 11 and the upper arm restraint strap 13 are fixed in the corresponding positions, the diagonal strap 5 is wrapped around the patient's shoulder and then fixed to the fixing buckle 7 of the chest restraint strap 11 using the fixing buckle 6 to prevent the restraint strap from slipping down and improve the reliability of the restraint strap fixation. In addition, there are several fixing buckles 7, which can be adjusted according to the patient's body shape to improve the adaptability and versatility of the restraint strap.
[0039] The chest restraint strap 11 and the upper arm restraint strap 13 are fixedly connected by a first limiting strap 12. The first limiting strap 12 can limit the distance between the upper arm restraint strap 13 and the chest restraint strap 11, thereby restricting the range of motion of the patient's upper arm.
[0040] like Figure 5 and Figure 6 As shown, a hook-and-loop fastener 111 is fixedly attached to the inner side of one end of the chest restraint strap 11, and a loose-fitting hook-and-loop fastener 112 is fixedly attached to the outer side of the other end, opposite to the hook-and-loop fastener 111. The hook-and-loop fastener 111 can be opened and closed and adhered to the loose-fitting hook-and-loop fastener 112, thereby tightening and fixing the chest restraint strap 11. The chest restraint strap 11 is tightened and fixed by the adhesion of the hook-and-loop fastener 111 and the loose-fitting hook-and-loop fastener 112, and the tightness of the chest restraint strap 11 can be adjusted according to the size of the patient's chest. This ensures the fixing effect of the restraint strap while avoiding excessive tightness that may cause patient discomfort. It is also easy to operate and convenient for medical staff or patients to wear and adjust.
[0041] like Figure 3 As shown, an upper arm hook-and-loop fastener 131 is fixedly provided on the inner side of one end of the upper arm restraint strap 13, and an upper arm loop fastener 132 opposite to the upper arm hook-and-loop fastener 131 is fixedly provided on the outer side of the other end; the upper arm hook-and-loop fastener 131 can be opened and closed and adhered to the upper arm loop fastener 132, thereby enabling the upper arm restraint strap 13 to be tightened and fixed.
[0042] The abdominal restraint strap 21 and the forearm restraint strap 23 are fixedly connected by a second limiting strap 22, which limits the distance between the forearm restraint strap 23 and the abdominal restraint strap 21, thereby restricting the range of motion of the patient's forearm.
[0043] like Figure 7 As shown, an abdominal hook-and-loop fastener 211 is fixedly provided on the inner side of one end of the abdominal restraint strap 21, and an abdominal loop fastener 212 opposite to the abdominal hook-and-loop fastener 211 is fixedly provided on the outer side of the other end; the abdominal hook-and-loop fastener 211 can be opened and closed and adhered to the abdominal loop fastener 212, thereby enabling the abdominal restraint strap 21 to be tightened and fixed.
[0044] like Figure 4 As shown, a forearm hook-and-loop fastener 231 is fixedly provided on the inner side of one end of the forearm restraint strap 23, and a forearm loop fastener 232 opposite to the forearm hook-and-loop fastener 231 is fixedly provided on the outer side of the other end; the forearm hook-and-loop fastener 231 can be opened and closed and adhered to the forearm loop fastener 232, thereby enabling the forearm restraint strap 23 to be tightened and fixed.
[0045] The chest restraint strap 11, the upper arm restraint strap 13, the abdominal restraint strap 21, and the forearm restraint strap 23 are all made of fabric. The fabric is soft and breathable, making it comfortable against the patient's skin and reducing friction and pressure, thus improving patient acceptance and compliance.
[0046] The post-pacemaker implantation restraint band in this embodiment is used as follows:
[0047] First, the chest restraint strap 11 is tightened and fixed to the patient's chest using the hook-and-loop fasteners 111 and 112. Then, the upper arm restraint strap 13 is tightened and fixed to the patient's upper arm using the hook-and-loop fasteners 131 and 132. This completes the restraint of the patient's surgical arm. Next, the diagonal strap 5 is wrapped around the patient's shoulder, and then, according to the patient's body shape, the fixing buckle 6 is fixed to the appropriate fixing buckle 7 to prevent the restraint strap from slipping down. During the wearing process, if the patient feels discomfort in their chest or upper arm... If appropriate, first tighten and fix the abdominal restraint strap 21 to the patient's abdomen using the hook-and-loop fasteners 211 and 212. Then tighten and fix the forearm restraint strap 23 to the patient's forearm using the hook-and-loop fasteners 231 and 232. After that, remove the chest restraint strap 11 and the upper arm restraint strap 13. If the patient feels discomfort in the abdomen and forearm afterward, fix the chest restraint strap 11 and the upper arm restraint strap 13 in place, and then remove the abdominal restraint strap 21 and the forearm restraint strap 23. Repeat this process.
[0048] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this innovative technical solution.
