Abstract
Description
Technical Field
[0001] This invention relates to the field of postoperative recovery technology for pets, and more particularly to an elastic compression device for postoperative care of pet dogs. Background Technology
[0002] Postoperative elastic compression devices for dogs are auxiliary instruments specifically designed for postoperative recovery. Made of highly elastic and breathable material, they promote wound healing through gentle elastic compression while preventing secondary injury from licking or scratching. The design conforms to the curves of a dog's limbs and features an adjustable tension structure to ensure effective fixation while avoiding excessive pressure that could impair blood circulation. Some products are equipped with a bite shield to further reduce the risk of oral contact with the wound. In clinical applications, this device can be used in conjunction with external fixation braces or splints to provide stable support in fracture repair, joint surgery, and other procedures. Compared to traditional bandages, its advantages include superior breathability, durability, and the ability to be repeatedly washed and reused, significantly reducing the risk of postoperative infection and making it an important auxiliary tool in the field of veterinary medicine.
[0003] In actual use, after surgery, pet dogs often experience edema at the surgical site due to tissue damage, inflammation, or poor local blood circulation. Additionally, there may be exudate due to incomplete wound healing, and bacteria may remain at the surgical site. Traditional nursing methods are difficult to effectively control edema and exudate. Furthermore, the residual bacteria after compression and wrapping can easily increase the risk of infection. Therefore, an elastic compression device for postoperative care of pet dogs is proposed. Summary of the Invention
[0004] The purpose of this invention is to address the shortcomings of existing technologies, such as swelling at the surgical site after pet dog surgery due to tissue damage, inflammatory response, or poor local blood circulation, as well as the presence of exudate due to incomplete wound healing and residual bacteria at the surgical site. Traditional nursing methods are difficult to effectively control edema and exudate, and the risk of infection is increased due to residual bacteria after compression and wrapping. Therefore, this invention proposes an elastic compression device for pet dogs after surgery.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: A postoperative elastic compression device for pet dogs includes a compression shell. A control mechanism is located on the upper part of the compression shell, which drives an inner rod and an outer rod to rotate. A threaded rod is fixedly connected to the bottom of the inner rod, and a compression rod is threadedly connected to the threaded rod. A compression plate is fixedly connected to the bottom of the compression rod, and the compression plate is slidably connected to a compression cavity. The compression cavity is located inside the compression shell. A pressure sensor is installed inside the compression plate. A transmission belt is driven to the outer rod, and a transmission wheel is driven to the transmission belt. A fourth gear is fixedly connected to the transmission wheel, and the fourth gear meshes with a fifth gear. A sixth gear is fixedly connected to the fifth gear. A gear meshing connection is provided with a transmission rack, and a compression plate is fixedly connected to the bottom of the transmission rack. The compression plate is slidably connected to the compression housing. A compression housing is fixedly connected inside the compression chamber, and a compression rod is slidably connected inside the compression housing. During use, the activation control mechanism drives the inner rod and outer rod to rotate synchronously. The rotation of the inner rod causes the compression plate to move downward, thereby compressing the surgical site. During the compression process, the outer rod drives the compression plate to press down, causing the disinfectant placed inside to seep out and disinfect the area near the surgical site. The compression plate is made of silicone and has a snap-fit design, so it can be replaced directly after each compression. The compression housing and compression chamber are filled with disinfectant, which can be squeezed out by the compression plate.
[0006] The above technical solution further includes: The drive wheel is rotatably connected to the extrusion housing, and the extrusion housing is fixedly connected inside the compression shell.
[0007] The extrusion shell is fixedly connected to a limiting groove, and a transmission rack is slidably connected inside the limiting groove.
[0008] The control mechanism includes a control housing fixedly connected to the top of the outer shell, a second motor is provided inside the control housing, and a control component is provided at the output end of the second motor.
[0009] The control component includes a first gear located at the output end of a second motor, a third gear meshing with the first gear, an outer rod fixedly connected to the lower part of the third gear, and the outer rod being rotatably connected to the control housing.
[0010] The first gear is meshed with a second gear, and the second gear is fixedly connected to an inner rod. The inner rod and the outer rod are rotatably connected.
[0011] The bottom of the compression housing is fixedly connected to a disinfection pad ring, and the top of the compression housing is equipped with a display. The disinfection pad ring is fixedly connected to the outer ring of the compression housing, and the upper part of the disinfection pad ring and the compression housing are provided with several permeation holes. The disinfectant can be discharged through the permeation holes under the pressure of the extrusion plate. The display can reflect the pressure data collected by the pressure sensor in real time.
[0012] The compression shell is fixedly connected to both sides of the fixed belt shell. A first motor is provided on one side of the fixed belt shell. A rotating shaft is provided at the output end of the first motor. The rotating shaft is rotatably connected to the fixed belt shell. A fixed belt is provided around the outside of the rotating shaft.
[0013] One end of the fixing strap is fixedly connected with Velcro, and the upper part of the fixing strap has ventilation holes.
[0014] The present invention has the following beneficial effects: 1. In this invention, after the device is fixed by the fixing strap, the control mechanism can be activated to drive the inner rod and the outer rod to rotate synchronously. The rotation of the inner rod can drive the compression plate to move downward, thereby gradually compressing the surgical site. Moreover, the pressure sensor installed inside the compression plate can monitor the compression force in real time and reflect it on the display, which makes it easy for personnel to adjust the compression force. During the downward pressing of the compression plate, the outer rod can drive the squeezing plate to move downward simultaneously, so that the disinfectant inside the compression shell can seep out from the disinfection pad ring, automatically disinfecting the surgical compression area, effectively killing residual bacteria after surgery, and also providing a stable and effective compression effect to avoid tissue edema.
[0015] 2. In this invention, before use, the first motor can be started to drive the rotating shaft to rotate, thereby causing the fixation strap to extend. Doctors can flexibly select the extension length of the fixation strap according to the surgical site, effectively ensuring the adaptability of the surgical position. Moreover, after the compression is completed, the fixation strap can be automatically retracted by controlling the first motor to reverse, which improves the effectiveness of the device.

A threaded rod 28 is fixedly connected to the bottom of the inner rod 18, and a compression rod 29 is threadedly connected to the threaded rod 28. A compression plate 9 is fixedly connected to the bottom of the compression rod 29, and the compression plate 9 is slidably connected to a compression cavity 11. The compression cavity 11 is located inside the compression shell 1. A pressure sensor 30 is installed inside the compression plate 9. A transmission belt 14 is driven to the outer rod 20, and a transmission wheel 21 is driven to the transmission belt 14. A fourth gear 22 is fixedly connected to the transmission wheel 21, and a fifth gear 23 is meshed with the fourth gear 22. A sixth gear 24 is fixedly connected to the fifth gear 23. A transmission rack 25 is meshed with the compression chamber 11. A compression plate 13 is fixedly connected to the bottom of the transmission rack 25. The compression plate 13 is slidably connected to the compression shell 1. A compression shell 27 is fixedly connected inside the compression chamber 11. A compression rod 29 is slidably connected inside the compression shell 27. During use, the start control mechanism drives the inner rod 18 and the outer rod 20 to rotate synchronously. The rotation of the inner rod 18 drives the compression plate 9 to move downward to compress the surgical position. During the compression process, the outer rod 20 drives the compression plate 13 to press down, causing the disinfectant placed inside to seep out and disinfect the area near the surgical position. The compression plate 9 is made of silicone and is snap-fit. It can be replaced directly after each compression. The compression shell 1 and the compression chamber 11 are filled with disinfectant. The compression plate 13 can compress the disinfectant to seep out.
[0020] The transmission wheel 21 is rotatably connected to the extrusion housing 12, which is fixedly connected inside the extrusion housing 1. A limit groove 26 is fixedly connected inside the extrusion housing 12, and a transmission rack 25 is slidably connected inside the limit groove 26. The control mechanism includes a control housing 4 fixedly connected to the top of the extrusion housing 1. A second motor 15 is installed inside the control housing 4, and a control component is installed at the output end of the second motor 15. The control component includes a first gear 16 installed at the output end of the second motor 15, which meshes with a third gear 19. An outer... Rod 20 is rotatably connected to the outer rod 20 and the control housing 4. The first gear 16 is meshed with the second gear 17. The second gear 17 is fixedly connected to the inner rod 18. The inner rod 18 is rotatably connected to the outer rod 20. The bottom of the pressure housing 1 is fixedly connected to the disinfection pad ring 8. The top of the pressure housing 1 is provided with the display 5. The disinfection pad ring 8 is fixedly connected to the outer ring of the pressure housing 1. Moreover, the disinfection pad ring 8 and the upper part of the pressure housing 1 are provided with several permeation holes. The disinfectant can be discharged through the permeation holes under the pressure of the extrusion plate 13. The display 5 can reflect the pressure data collected by the pressure sensor 30 in real time.
[0021] In this embodiment, after the device is fixed by the fixing strap 31, starting the second motor 15 can drive the first gear 16 to rotate. The rotation of the first gear 16 drives the meshing second gear 17 and third gear 19 to rotate synchronously. The rotation of the second gear 17 can drive the fixedly connected inner rod 18 to rotate, and the rotation of the third gear 19 can drive the fixedly connected outer rod 20 to rotate, thereby realizing the synchronous rotation of the inner rod 18 and the outer rod 20. The rotation of the inner rod 18 can drive the fixedly connected threaded rod 28 to rotate, and the rotation of the threaded rod 28 can drive the threadedly connected pressure rod 29 to move, thereby driving the pressure plate 9 to move downward, thereby gradually compressing the surgical site. Moreover, the pressure sensor 30 set inside the pressure plate 9 can monitor the pressure force in real time and reflect it on the display 5, which makes it convenient for personnel to adjust the pressure force.
[0022] During the downward pressing of the compression plate 9, the outer rod 20 can synchronously drive the transmission belt 14 to rotate. The rotation of the transmission belt 14 drives the transmission wheel 21 connected to the transmission to rotate. The rotation of the transmission wheel 21 drives the fixedly connected fourth gear 22 to rotate. The rotation of the fourth gear 22 drives the meshing fifth gear 23 to rotate. The rotation of the fifth gear 23 drives the fixedly connected sixth gear 24 to rotate. The rotation of the sixth gear 24 drives the meshing transmission rack 25 to move. During the movement of the transmission rack 25, the slidingly connected limiting groove 26 can ensure its stability during movement. The movement of the transmission rack 25 can drive the fixedly connected compression plate 13 to move downward, thereby squeezing the disinfectant inside the compression shell 1 and causing it to seep out from the disinfection pad ring 8, automatically disinfecting the surgical compression area, effectively killing residual bacteria after surgery, and also providing a stable and effective compression effect to avoid tissue edema.

A rotating shaft 7 is provided at the output end of the first motor 2. The rotating shaft 7 is rotatably connected to the fixed belt housing 3. A fixed belt 31 is arranged around the outside of the rotating shaft 7. A Velcro 10 is fixedly connected to one end of the fixed belt 31. A ventilation hole 6 is opened on the upper part of the fixed belt 31.
[0024] In this embodiment, before use, the first motor 2 can be started to drive the rotating shaft 7 to rotate, thereby causing the fixing strap 31 to extend. The doctor can flexibly select the extension length of the fixing strap 31 according to the surgical site, effectively ensuring the adaptability of the surgical position. After extension, the fixing straps 31 on both sides can be fixed by Velcro 10. Moreover, during the compression process, the ventilation hole 6 opened on the upper part of the fixing strap 31 can effectively ensure ventilation and avoid discomfort to the pet dog caused by excessive compression time. After compression is completed, the fixing strap 31 can be automatically retracted by controlling the first motor 2 to reverse, which improves the use effect of the device.
