Technical Field
[0001] This invention relates to the field of postoperative protection technology, and in particular to a postoperative wound infection prevention and protection device. Background Technology
[0002] Pacemaker implantation is a procedure in which a pacemaker is implanted in the heart. A specific frequency of pulsed current is delivered through leads and electrodes to stimulate the heart, replacing the heart's natural pacemaker and driving its beat. It is a safe and effective treatment for irreversible cardiac pacing and conduction dysfunction, particularly for severe chronic arrhythmias. After pacemaker implantation, the surgical wound needs to be protected to prevent infection. Current protective measures simply involve bandaging the wound with gauze. This simple bandaging does not provide adequate protection. When the patient showers or cleans themselves, the gauze easily becomes wet, and the wound comes into contact with water. Water contact can lead to infection and prolong the healing process.
[0003] Therefore, there is a need to design a postoperative wound protection device for cardiac pacemakers that can isolate the postoperative wound from the outside world to prevent infection. Summary of the Invention

[0038] The technical solutions in the embodiments of the present invention will be clearly and completely described below. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0039] Example 1: A postoperative wound infection prevention and protection device, such as Figures 1-6 As shown, the device includes a first protective shell 1, a second protective shell 2, a first mounting block 3, a second mounting block 4, a pressure ring 5, a slider 501, a fixing block 6, a first spring 7, and a fastening mechanism. The second protective shell 2 is connected to the rear side of the first protective shell 1. The first mounting block 3 is fixedly connected to the front of the upper part and the front of the left and right sides of the first protective shell 1. The second mounting block 4 is connected to the rear left side of the first protective shell 1. The pressure ring 5 is slidably connected to the inner front side of the first protective shell 1. A rubber pad is provided on the front side of the pressure ring 5. The middle of the left and right sides inside the first protective shell 1 is connected to the fixing block 6. The slider 501 is slidably connected to the fixing block 6. The first spring 7 is connected between the upper and lower parts of the slider 501 and the rear side of the fixing block 6. The slider 501 is connected to the inner side of the pressure ring 5. A fastening mechanism is provided on the outer side of the first protective shell 1. The fastening mechanism is used to fix the device to the patient.
[0040] like Figures 1-2 and Figures 5-6As shown, the fastening mechanism includes a first fastening strap 8, a second fastening strap 9, a third fastening strap 10, and a buckle 11. The first fastening strap 8 is fixedly installed on the upper first mounting block 3, the second fastening strap 9 is installed on the right first mounting block 3, and the third fastening strap 10 is installed on the left first mounting block 3. The first fastening strap 8, the second fastening strap 9, and the third fastening strap 10 are connected by the buckle 11. The first fastening strap 8, the second fastening strap 9, and the third fastening strap 10 are all made of elastic material.
[0041] This device can be used when postoperative wound protection is needed after pacemaker implantation. The patient places the front of the pressure ring 5 over the wound, ensuring it is in contact with the skin. The rubber pad on the front of the pressure ring 5 prevents skin abrasions. Then, the first binding strap 8 is wrapped around the patient's left shoulder to the back. The second binding strap 9 and the third binding strap 10 are wrapped around the patient's left and right armpits to the back, respectively. Finally, the first binding strap 8, second binding strap 9, and third binding strap 10 are fastened together using the buckle 11, thus securing the device to the patient. All three binding straps are made of elastic material, making the device suitable for patients of different body types. During the fastening process of the first binding strap 8, second binding strap 9, and third binding strap 10… The first protective shell 1 moves forward under the tension of the first binding strap 8, the second binding strap 9, and the third binding strap 10. The first spring 7 is compressed. The forward movement of the first protective shell 1 applies forward pressure to the pressure ring 5, thereby allowing the pressure ring 5 to make close contact with the skin. The first protective shell 1, the second protective shell 2, and the pressure ring 5 form a closed environment, which can protect the postoperative wound, isolate the wound from the outside world, prevent the patient from accidentally touching the wound, and prevent the wound from coming into contact with water, thus affecting wound healing. When people need to remove this device, they can release the buckle 11, then separate the second binding strap 9 and the first binding strap 8 from the third binding strap 10, and then remove the device. The first spring 7 returns to its original position, causing the first protective shell 1 to move backward to reset.
[0042] Example 2: Based on Example 1, such as Figures 7-10As shown, it also includes a cover ring 12, a connecting frame 13, a fixing ring 14, a first limiting post 15, a second spring 16, and a handle 17. A fixing ring 14 is fixedly connected to the middle of the rear side of the second protective shell 2. Holes 1401 are opened on the lower right and lower sides of the fixing ring 14. The connecting frame 13 is rotatably connected inside the second protective shell 2. Four cover rings 12 are circumferentially connected to the outer side of the connecting frame 13. Four ventilation holes 1201 are opened on the second protective shell 2. The cover rings 12... The ventilation hole 1201 can be covered. The middle rear part of the connecting frame 13 passes through the middle rear part of the second protective shell 2. A handle 17 is connected to the middle rear part of the connecting frame 13. A first limiting post 15 is snapped onto the handle 17. The first limiting post 15 can pass through the handle 17 and be inserted into the hole 1401 of the fixing ring 14. The middle front part of the connecting frame 13 passes through the middle front part of the second protective shell 2. A second spring 16 is connected between the middle front part of the connecting frame 13 and the middle front part of the second protective shell 2.
[0043] The wound needs regular ventilation to prevent it from remaining closed for extended periods and prolonging healing time. Initially, the cover ring 12 covers the ventilation hole 1201 on the second protective shell 2. When ventilation is needed, the first limiting post 15 is removed, and then the handle 17 is rotated 45 degrees clockwise. This clockwise rotation of the handle 17 causes the connecting frame 13 to rotate, which in turn causes the cover ring 12 to rotate clockwise. The second spring 16 deforms, and the first limiting post 15 is then inserted through the handle 17 into the hole 1401 on the lower right side of the fixing ring 14, thus fixing the handle 17. This, in turn, fixes the connecting frame 13 and the cover ring 12, and the cover ring 12 no longer obstructs the second protective shell 2. The ventilation holes 1201 on the second protective shell 2 can achieve ventilation, preventing the wound from being in a closed environment for a long time, which would prolong the wound healing time. When it is time to take a shower, the first limiting post 15 can be removed, and the second spring 16 will return to its original shape, causing the connecting frame 13 and the cover ring 12 to rotate counterclockwise and reset, thereby causing the handle 17 to reset. Finally, the first limiting post 15 is inserted through the handle 17 into the hole 1401 on the lower side of the fixing ring 14, thereby fixing the connecting frame 13 and the cover ring 12. The cover ring 12 then covers the ventilation holes 1201 on the second protective shell 2, which can isolate the postoperative wound from the outside world and prevent the wound from coming into contact with water during showering, thus preventing wound infection.
[0044] like Figures 11-13As shown, it also includes a sponge pad 18, a fixing plate 19, a connecting bracket 1901, a fixing frame 20, and a fifth spring 2001. The fixing frame 20 is connected inside the first protective shell 1. The connecting bracket 1901 is slidably connected to the middle of the fixing frame 20. The fixing plate 19 is fixedly connected to the front side of the connecting bracket 1901. Multiple fifth springs 2001 are connected between the fixing frame 20 and the fixing plate 19. The fifth springs 2001 are all wrapped around the connecting bracket 1901. The sponge pad 18 is sleeved on the front side of the fixing plate 19. The sponge pad 18 can be removed. The sponge pad 8 is located inside the pressure ring 5.
[0045] After a pacemaker is implanted, it needs to be pressed and secured, and pressure applied to the wound to stop bleeding. When the first protective shell 1 moves forward, it moves the fixation frame 20 forward, which in turn moves the fixation plate 19, connecting bracket 1901, and sponge pad 18 forward. The sponge pad 18 moves forward and comes into contact with the wound. The first protective shell 1 continues to move forward, moving the fixation frame 20 forward. The fifth spring 2001 is compressed, making the sponge pad 18 in close contact with the wound. The sponge pad 18 exerts a certain pressure on the wound, thereby achieving the function of compression and hemostasis. It can also compress and secure the pacemaker controller under the wound, preventing the subcutaneously implanted pacemaker controller from moving. When the device is removed after use, the first protective shell 1 moves backward, moving the fixation frame 20 backward. This causes the fifth spring 2001 to reset, moving the fixation plate 19, connecting bracket 1901, and sponge pad 18 backward.
[0046] like Figures 14-17 As shown, it also includes a first support rod 21, a second support rod 22, a fixed rod 23, a second limiting post 24, a limiting block 25, a third spring 26, and a fourth spring 27. The first support rod 21 is rotatably connected to the second mounting block 4. The second support rod 22 is rotatably connected to the left side of the first support rod 21. The fixed rod 23 is rotatably connected to the left side of the second support rod 22. The second limiting post 24 is slidably engaged with the rear side of the second mounting block 4. The limiting block 25 is slidably connected to the rear left side of the second support rod 22. The limiting block 25 limits the fixed rod 23. Multiple third springs 26 are connected between the limiting block 25 and the second support rod 22. The fourth spring 27 is connected between the right side of the fixed rod 23 and the front and rear parts of the left side of the second support rod 22.
[0047] After a pacemaker is implanted, the arm needs to be immobilized to prevent it from moving around and aggravating the wound. Initially, the fourth spring 27 is in a deformed state, while the third spring 26 is in a non-deformed state. The elastic coefficient of the fourth spring 27 is greater than that of the third spring 26. When using this device, the left side of the fixing rod 23 can be used to fix the left arm to prevent it from moving around and aggravating the wound. After using this device, it can be removed. Pulling the limiting block 25 to the right compresses the third spring 26, and the limiting block 25 moves downward, no longer limiting the fixing rod 23. The fourth spring 27 returns to its deformed state, causing the fixing rod 23 to rotate backward and reset. Since the elastic coefficient of the fourth spring 27 is greater than that of the third spring 26, the fixing rod 23 can abut against the limiting block 25. Then, the second support rod 22 is rotated backward, causing the components on the fixing rod 23 and the second support rod 22 to rotate backward. Finally, the second limiting post 24 is slid upward and removed, the first support rod 21 is rotated backward by 90 degrees, and the second limiting post 24 is inserted back into the second mounting block. 4. The second limiting post 24 can limit and fix the first support rod 21, preventing it from rotating freely. The first support rod 21 rotating backward causes the fixing rod 23, the second support rod 22, and the components on the second support rod 22 to rotate backward, thus achieving the storage of the device and preventing it from being too long and occupying storage space. When needed, the second limiting post 24 is removed, the first support rod 21 is rotated forward 90 degrees, and then the second limiting post 24 is inserted back into the second mounting block 4. The forward rotation causes the fixed rod 23, the second support rod 22, and the components on the second support rod 22 to rotate forward. Then, the second support rod 22 rotates forward, causing the fixed rod 23 and the components on the second support rod 22 to rotate forward. Finally, the fixed rod 23 rotates forward, and the fourth spring 27 deforms. When the fixed rod 23 rotates forward and no longer presses against the limiting block 25, the third spring 26 returns to its original deformation, causing the limiting block 25 to move to the left and limit the fixed rod 23 again, which facilitates the subsequent use of this device.
[0048] like Figures 18-19 As shown, it also includes a placement box 28, a pressure plate 29, a telescopic hose 30, an input pipe 31, and a cover 32. The placement box 28 is connected to the rear side of the inside of the first protective shell 1. The placement box 28 is used to store medicine. The pressure plate 29 is slidably connected inside the placement box 28. The rear side of the middle of the connecting bracket 1901 contacts the front side of the pressure plate 29. The telescopic hose 30 is fixedly connected to the upper rear side of the placement box 28. The telescopic hose 30 communicates with the placement box 28. The front side of the telescopic hose 30 communicates with the fixed plate 19. The input pipe 31 is connected to the upper right rear of the placement box 28. The upper part of the input pipe 31 passes through the upper right rear of the first protective shell 1. The upper end of the input pipe 31 is snapped with a cover 32, which can prevent dust from entering.
[0049] The patient's wound needs to be treated regularly. When medication is needed, the lid 32 is opened, and an appropriate amount of medication is poured into the inlet tube 31. The medication flows into the placement box 28 through the inlet tube 31. The lid 32 is then closed. As the first protective shell 1 continues to move forward, it moves the placement box 28 and the pressure plate 29 forward. The pressure plate 29 moves forward and contacts the connecting bracket 1901, causing the telescopic hose 30 to retract. The first protective shell 1 continues to move forward, moving the placement box 28 and the pressure plate 29 forward. The connecting bracket 1901 squeezes the pressure plate 29, causing it to slide backward within the placement box 28 and squeeze the medication inside. This allows the medication to flow through the telescopic hose 30 to the front of the fixing plate 19 and finally into the sponge pad 18. Since the sponge pad 18 is in contact with the wound, medication can be applied to the wound, preventing infection. When the first protective shell 1 moves backward, it moves the placement box 28 and the pressure plate 29 back to their original positions, and the telescopic hose 30 extends back to its original position.
