Description

Technical Field

[0001] This utility model relates to the field of medical devices, and in particular to an upper limb abduction fixation bra for use after pacemaker implantation. Background Technology

[0002] Pacemaker implantation is a medical procedure used to treat heart arrhythmias, particularly bradycardia (a heart rate that beats too slowly). A pacemaker is a small electronic device that uses electrical pulses to stimulate the heart, keeping it beating at a normal rate and ensuring the heart pumps blood effectively.

[0003] Absolute bed rest is required for 24-72 hours post-pacemaker implantation. The patient should lie supine on the first day and slightly to the left on the second day. The operated limb should be immobilized for one week post-surgery. For the first 1-3 days post-surgery, the operated limb should not be moved, avoiding flexion and elevation. In the early postoperative period, the lead is not fully fixed, and excessive abduction may lead to lead displacement or dislocation. Multiple studies have shown that restricting upper limb activity for 1-2 weeks post-surgery significantly reduces the risk of lead displacement. Excessive upper limb activity may affect pocket healing and increase the risk of bleeding or infection. Clinical data shows that restricting upper limb activity helps reduce pocket-related complications. Guidelines from multiple cardiology societies recommend restricting upper limb activity post-surgery, especially abduction and elevation. For example, guidelines from the American Heart Association (AHA) and the European Society of Cardiology (ESC) recommend avoiding excessive upper limb activity for 4-6 weeks post-surgery. Studies indicate that patients who adhere to activity restrictions have fewer postoperative complications and better recovery. The recommendation of limiting upper limb abduction to no more than 30 degrees post-surgery is based on lead stability, pocket healing, clinical indications, and patient feedback, aiming to reduce the risk of complications and promote recovery. When performing limb function exercises 7 days after surgery, the principle of gradual progression should be followed (early postoperative limb function exercises are beneficial to local blood circulation and wound healing).

[0004] Therefore, for patients with poor compliance, limb immobilization cannot be completed entirely by self-restraint and requires assisted control of limb immobilization. Otherwise, it will increase the risk of complications such as lead displacement and capsule healing. To address this issue, an upper limb abduction fixation bra for pacemaker implantation is proposed. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides an upper limb abduction fixation bra for pacemaker implantation, which aims to improve the problem in the prior art where patients with poor compliance cannot fully rely on their own restraint to complete limb immobilization and need to rely on auxiliary control of limb immobilization, otherwise it will increase the risk of complications such as lead displacement and capsule healing.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: an upper limb abduction fixation bra for pacemaker implantation, comprising a bra, wherein a connecting strap a is fixedly connected to the outer wall of the bra, and an adjustment component is provided at the end of the connecting strap a away from the bra;

[0007] The adjustment assembly includes a fixing block. The bottom end of the inner wall of the fixing block is elastically connected to a winding shaft via a spiral spring. The inner wall of the top end of the winding shaft is elastically connected to a pressing rod via a return spring. A limit block is fixedly connected to the surface of the pressing rod.

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Reference Figures 1-3 An embodiment of this utility model provides an upper limb abduction fixation bra for pacemaker implantation, comprising a bra 1, with a connecting strap a2 fixedly connected to the outer wall of the bra 1. The connecting strap a2 is a nylon strap in the prior art, which is sewn to the side wall of the bra 1 by sewing. The connecting strap b6 is also sewn to the outside of the arm strap 4 by sewing. An adjustment component 3 is provided at the end of the connecting strap a2 away from the bra 1.

[0033] Reference Figures 2-3 The adjustment component 3 includes a fixing block 31, with a connecting strap a2 passing through and slidably connected to the inner wall of the fixing block 31. A guide groove is provided on the side wall of the fixing block 31, allowing the connecting strap a2 to pass through the guide groove and be wound around its surface by the rotation of the winding shaft 33. This adjusts the overall length of the connecting strap a2, allowing for adjustment of the abduction angle according to the patient's pacemaker implantation position. Excessive abduction, before the lead is fully fixed, may cause lead displacement or dislocation. The winding shaft 33 is wound around the surface of the take-up shaft 33. The bottom end of the inner wall of the fixing block 31 is elastically connected to the take-up shaft 33 via a spiral spring 32. The take-up shaft 33 is rotatably connected to the inner wall of the fixing block 31. One end of the spiral spring 32 is fixedly connected to the central axis at the bottom end of the take-up shaft 33, and the other end of the spiral spring 32 is fixedly connected to the bottom end of the inner wall of the fixing block 31. The function of the spiral spring 32 is to automatically reset the position of the connecting belt a2 after the take-up shaft 33 is rotated and unfolded, so that the connecting belt a2 can be quickly wound up.

[0034] Reference Figure 2 and Figure 3A pressing rod 35 is elastically connected to the inner wall of the top end of the take-up shaft 33 via a return spring 34. One end of the return spring 34 is fixedly connected to the inner wall of the top end of the take-up shaft 33, and the other end is fixedly connected to the bottom end of the outer wall of the pressing rod 35. The function of the return spring 34 is to automatically reset the position of the pressing rod 35 after it has been pressed and moved. The pressing rod 35 is slidably connected to the inner wall of the top end of the take-up shaft 33. A guide groove is provided at the top end of the take-up shaft 33, so that the pressing rod 35 can only slide up and down on the inner wall of the top end of the take-up shaft 33. A limiting block 36 is fixedly connected to the surface of the pressing rod 35. A limiting groove is provided at the top end of the fixing block 31. The outer wall of the limiting block 36 is in contact with the inner wall of the limiting groove at the top end of the fixing block 31. The contact between the two causes the take-up shaft 33 to rotate and drive the connecting belt a2 to be stretched and unfolded, and then fixed at multiple positions to adjust the overall length of the connecting belt a2 according to the unfolding angle of the patient. A rotating block 37 is rotatably connected to the top of the outer wall of the pressing rod 35. The rotating block 37 is configured to rotate so that when the pressing rod 35 and the limiting block 36 are lowered, the winding shaft 33 will be automatically reset by the elastic action of the spiral spring 32, thereby quickly winding up the connecting belt a2. The rotating block 37 does not rotate with the rotation of the pressing rod 35. The pressing rod 35 passes through and is slidably connected to the inner wall of the fixing block 31. The end of the fixing block 31 away from the connecting belt a2 is fixedly connected to the connecting belt b6. The outer wall of the connecting belt b6 is fixedly connected to the arm strap 4. The surfaces of the bra 1 and the arm strap 4 are provided with Velcro 5. By providing Velcro 5 on the surfaces of the bra 1 and the arm strap 4, the bra 1 can be adjusted according to the size of the patient's upper body, and the arm strap 4 can be adjusted according to the width of the patient's arm. The Velcro 5 on both the arm strap 4 and the bra 1 has a hook side and a fleece side.

[0035] Reference Figure 1 and Figure 4The bra 1 includes a breathable layer 11 with multiple sets of ventilation holes on its surface. The breathable layer 11 is made of a hollow-woven material, and through a special weaving process, many small holes are formed in the fabric, increasing airflow and improving heat dissipation. A metal fiber layer 12 is fixedly connected to the bottom of the outer wall of the breathable layer 11. The metal fiber layer 12 is made of copper fiber, which has good thermal conductivity and antibacterial properties, enabling it to quickly conduct away the heat generated by the body, improving heat dissipation. At the same time, copper fiber can inhibit bacterial growth, keeping the bra 1 clean and hygienic. An antibacterial layer 13 is fixedly connected to the bottom of the outer wall. The antibacterial layer 13 is made of nano-silver, which has antibacterial and deodorizing effects, and can also reflect heat to improve heat dissipation. A fabric layer 14 is fixedly connected to the bottom of the outer wall of the antibacterial layer 13. The fabric layer 14 is made of Modal fiber, which is a natural wood pulp fiber. It has a soft and smooth feel and good moisture absorption. At the same time, it has very good breathability, which allows air to circulate freely and helps dissipate heat. The order of the above materials from the inside to the outside is: breathable layer 11, metal fiber layer 12, antibacterial layer 13 and fabric layer 14.

[0036] Working principle: When it is necessary to adjust the abduction angle of the upper limb, first press the rotating block 37 to drive the pressing rod 35 and the limiting block 36 to descend, thereby allowing the limiting block 36 to disengage from the limiting groove of the current position of the fixed block 31. At this time, pull the connecting belt a2, which drives the winding shaft 33 to rotate. The connecting belt a2 unfolds from the surface of the winding shaft 33. At this time, the winding shaft 33 rotates and compresses the spiral spring 32. When the connecting belt a2 is stretched to a suitable length, and the upper limb is abducted to a suitable angle, the limiting block 36 contacts the limiting groove at the top of the fixed block 31 under the action of the return spring 34, fixing the position of the winding shaft 33, thereby fixing the length of the connecting belt a2 and the abduction angle of the upper limb. To reduce the abduction angle, press the rotating block 37, which drives the pressing rod 35 and the limiting block 36 to descend, causing the limiting block 36 to disengage from the limiting groove. The winding shaft 33 automatically resets under the elastic action of the spiral spring 32, quickly winding up the connecting belt a2.

[0037] When the patient wears the bra 1, the Velcro 5 on the surface of the bra 1 can be adjusted according to the size of the upper body to make it fit the body. The arm strap 4 is connected to the bra 1 through the connecting strap b6, and the Velcro 5 on the surface of the arm strap 4 can be adjusted according to the width of the patient's arm to ensure that the arm strap 4 is comfortably fixed on the arm and works in conjunction with the bra 1 to achieve fixation of upper limb abduction.

[0038] This upper limb abduction fixation bra 1, used after pacemaker implantation, consists of, from the inside out, a breathable layer 11, a metal fiber layer 12, an antibacterial layer 13, and a fabric layer 14. The innermost breathable layer 11 has ventilation holes on its surface, made of a hollow woven material. The small holes formed by a special process increase air circulation, effectively dissipating body heat and keeping the chest dry. The metal fiber layer 12, fixed to the bottom of the outer wall of the breathable layer 11, is made of copper fiber. Its excellent thermal conductivity accelerates heat conduction, and its antibacterial properties inhibit bacterial growth, keeping the bra 1 clean. The antibacterial layer 13, at the bottom of the outer wall of the metal fiber layer 12, is made of nano-silver material, which is antibacterial, deodorizing, inhibits bacterial growth and odor production, and also reflects heat to assist in heat dissipation. The outermost fabric layer 14 is made of Modal fiber. This natural wood pulp fiber has a soft and smooth feel, good moisture absorption to absorb sweat, and excellent breathability, further improving the patient's comfort and heat dissipation experience.
