Description

Technical Field

[0001] The present invention relates to the technical field of orthopedic instruments, and in particular to an auxiliary device for treating lower limb injuries. Background Art

[0002] Lower limb trauma is a common condition in clinical orthopedics. It typically occurs when a patient suffers a strong external impact, falls from height, or traffic accidents. In mild cases, the lower limb surface is injured and requires disinfection or spraying, while in severe cases, the lower limb bones are damaged and require surgery. Whether it is a surface injury or bone damage, rapid treatment or treatment is urgently needed. If not handled promptly or improperly, it can easily lead to complications such as orthopedic wound infection, which not only causes pain to the patient but also prolongs recovery time and significantly reduces the patient's quality of life.

[0003] In current orthopedic clinics, lower limb trauma is typically treated manually, such as through manual disinfection or spraying. Manual procedures have many drawbacks, including uneven and incomplete disinfection and uneven application of medication, which can irritate the patient, cause pain, and worsen infection. Therefore, there is an urgent need for an auxiliary device to assist in the treatment of lower limb trauma, alleviate pain, and reduce adverse reactions.

[0004] A Chinese patent with publication number CN211486185U discloses an auxiliary device for orthopedic clinical trauma treatment, including a fixed frame and a support plate. The inner wall of the fixed frame is fixedly connected to a glass plate. A through groove is opened in the middle of the surface of the glass plate. A support rod is slidably connected to the inside of the through groove. One end of the support rod is fixedly connected to a rubber block, and the other end of the support rod is fixedly connected to a spray head. One end of the spray head is fixedly connected to a connecting pipe, and one end of the connecting pipe is movably connected to a connecting block. A liquid storage barrel is provided on the surface of the support plate, and a water valve is threadedly connected to the bottom of one side of the liquid storage barrel. Through the setting of the support rod and the through groove, when a person uses it, he can first open the fixed frame, place the limb that needs to be treated for the wound inside the fixed frame, and then rotate the fixed frame to adjust the spray head to the position of the wound. Then, pinch the rubber block with your hand and move the spray head along the path inside the through groove through the support rod to disinfect the wound, thereby achieving the effect of convenient adjustment.

[0005] With regard to the above-mentioned and existing related technologies, the inventor believes that although it is convenient to disinfect the patient's wound to a certain extent, the following defects still exist: when using the above-mentioned auxiliary device to disinfect the patient's calf, it is necessary to first place the patient's wounded lower limb inside the fixed frame, then lock the fixed frame, and then adjust the position of the spray head, and finally manually adjust the spray head to disinfect the patient's wound.

The inner wall of the vertical frame 2 is fixedly connected with two limit rods 313, and the limit rods 313 are slidably connected with the mounting plate 301. The surface of the mounting plate 301 is fixedly connected with a splint 314, and the delivery pipe 306 passes through the splint 314. The inner wall of the base 1 is engaged with a waste liquid tank 320, and the upper surface of the waste liquid tank 320 is provided with a plurality of water permeable holes 322. When the paddle 312 is pulled, the paddle 312 will drive the C-shaped tube 303 to slide along the inner wall of the card frame 302, and the sliding of the C-shaped tube 303 will drive the atomizing nozzle 311 The spray nozzle 311 is moved to adjust the position of the spray nozzle 311 so that the spray nozzle 311 is aimed at the wound of the patient, and then the pressure pump 304 is started. The liquid inlet end of the pressure pump 304 begins to suck the disinfectant or liquid medicine in the bottle body 305 and transports the disinfectant or liquid medicine to the delivery pipe 306. The disinfectant or liquid medicine will then flow into the C-tube 303 and be atomized by the spray nozzle 311 and sprayed onto the patient's calf to disinfect the patient's calf wound. The operation process is simple and convenient, which greatly saves disinfection time. When the area of ​​the calf wound is large, the electric push rod 308 is started. The extension of the output end of the electric push rod 308 will drive the box 309 to rise. The movement of the box 309 will drive the push plate 310 to move.

The water permeable hole 322 can prevent large foreign objects from entering the waste liquid tank 320, and at the same time can increase the friction on the upper surface of the waste liquid tank 320 to prevent the patient's feet from slipping.Two cylindrical blocks 315 are fixedly connected to the outer wall of the C-shaped tube 303. The connection between the delivery tube 306 and the C-shaped tube 303 is located between the two cylindrical blocks 315. The cylindrical block 315 is located in the arc hole 307. The movement of the C-shaped tube 303 will drive the cylindrical block 315 to slide. The cylindrical block 315 prevents the C-shaped tube 303 from slipping out of the clamping frame 302. The outer wall of the card frame 302 is fixedly connected to a fixed plate 316. A round rod 317 slides horizontally through the fixed plate 316. One end of the round rod 317 is fixedly connected to a friction block 318. The friction block 318 passes through the arc hole 307 and abuts the outer wall of the C-shaped tube 303. The arc surface of the round rod 317 is covered with a first spring 319. The two ends of the first spring 319 are respectively fixed to the round rod 317 and the fixed plate 316. The first spring 319 will continue to contract. The round rod 317 will use the tension of the first spring 319 to force the friction block 318 to abut the surface of the C-shaped tube 303. This can prevent the C-shaped tube 303 from shifting after adjusting the C-shaped tube 303 to a suitable position, causing the atomizing nozzle 311 to deviate. The upper surface of the waste liquid tank 320 is fixedly connected to a retaining ring 321 made of rubber. The retaining ring 321 can prevent the disinfectant or liquid medicine from flowing to the ground.

[0049] like Figure 2 and Figure 7 as well as Figure 8 As shown, the surface of the H-shaped plate 41 is fixedly connected with a bent plate 42, and the bent plate 42 is fixedly connected to the supporting plate 43. The surface of the H-shaped plate 41 is fixedly connected with a square rod 44, and the surface of the square rod 44 is slidingly covered with an inserting plate 45. The surface of the vertical frame 2 is provided with a plurality of insertion holes 46, and the size of the insertion holes 46 is adapted to the size of the inserting plate 45. When the height of the supporting plate 43 needs to be adjusted during the disinfection of patients of different sizes, the bent plate 42 is first pulled upward, and the bent plate 42 will drive the H-shaped plate 41 to slide. The sliding of the square rod 44 with the help of the H-shaped plate 41 will drive the inserting plate 45 to slide. When the baffle After contacting the top of the inner wall of the socket 46, the insert plate 45 can be pulled along the surface of the square rod 44 in a direction away from the vertical frame 2, causing the insert plate 45 to slide out of the inner wall of the socket 46. The height of the support plate 43 can then be adjusted by sliding the H-shaped plate 41 along the surface of the vertical frame 2 with the help of the bent plate 42. After adjusting to the appropriate position, the insert plate 45 is aligned with the socket 46, and then the insert plate 45 is slid in the opposite direction. After the insert plate 45 passes through the socket 46, the bent plate 42 is released to restrict the position of the support plate 43. By adjusting the support plate 43 to different heights, patients of different body shapes can be lifted more comfortably. The surface of the insert plate 45 is provided with an inclined surface and a triangular protrusion. When the triangular protrusion on the surface of the insert plate 45 contacts the vertical frame 2, it can prevent the insert plate 45 from sliding out of the inner wall of the socket 46. The surface of the bent plate 42 is fixedly connected to the diagonal brace 47, which serves to increase the strength of the bent plate 42.

[0050] like Figure 9 and Figure 10 As shown, the bar frame 51 is inclined to the horizontal plane, and the inner wall of the bar frame 51 is slidably connected to a circular plate 52, which is rotatably connected to the roller 53. The delivery tube 306 is wound around the arc surface of the roller 53. When the output end of the electric push rod 308 contracts, the delivery tube 306 no longer squeezes the roller 53, and the circular plate 52 will drive the roller 53 to slide in the opposite direction due to its own gravity. At this time, the roller 53 will squeeze the delivery tube 306, thereby tightening the delivery tube 306 to prevent the delivery tube 306 from becoming loose and hanging on the ground, causing the delivery tube 306 to be stepped on and damaged, which will affect the next use. A strip hole 54 is provided on the surface of the strip frame 51, and a transmission plate 55 is slidably connected to the inner wall of the strip hole 54, and the transmission plate 55 is slidably connected to the circular plate 52. A second spring 56 is fixedly connected to the surface of the transmission plate 55, and one end of the second spring 56 is fixedly connected to the strip frame 51. When the roller 53 slides downward, the second spring 56 will continue to stretch. The transmission plate 55 will use the tension of the second spring 56 to accelerate the sliding speed of the circular plate 52, so that the circular plate 52 can be quickly reset. At the same time, it can also increase the squeezing force of the roller 53 on the conveying pipe 306 to ensure that the conveying pipe 306 is tightened.

[0051] Working principle: When it is necessary to disinfect the patient's calf wound, first inject the configured disinfectant or liquid medicine into the bottle 305. When the patient sits down, place the patient's thigh on the upper surface of the support plate 43. At this time, the support plate 43 will support the patient's thigh, thereby reducing the pressure on the patient's calf. At this time, the support plate 43 can also be slid along the surface of the bending plate 42 to adjust the position of the support plate 43, which is convenient for using the support plate 43. At this time, the inclined rod 47 can prevent the support plate 43 from falling off the surface of the bending plate 42. Then pull the paddle 312, the paddle 312 will drive the C-tube 303 to slide along the inner wall of the card frame 302, and the sliding of the C-tube 303 will drive the atomizing nozzle 311 to move, thereby adjusting the position of the atomizing nozzle 311 so that the atomizing nozzle 311 is aimed at the patient's wound. During this process, the C-tube 303 will drive the cylindrical block 315 to slide, and the cylindrical block 315 can prevent the C-tube 303 from slipping out of the card frame 302. On this basis, the cylindrical block 315 can also prevent the connection between the delivery tube 306 and the C-tube 303 from being squeezed by the card frame 302, thereby affecting the normal flow of disinfectant or liquid medicine. The first spring 319 will continue to contract, and the round rod 317 will use the tension of the first spring 319 to make the friction block 318 press against the surface of the C-tube 303, thereby preventing the C-tube 303 from being displaced after the C-tube 303 is adjusted to a suitable position, causing the atomizing nozzle 311 to be offset. Then the pressure pump 304 is started, and the liquid inlet end of the pressure pump 304 begins to suck the disinfectant or liquid medicine in the bottle body 305 and transport the disinfectant or liquid medicine to the delivery pipe 306. The disinfectant or liquid medicine will then flow into the C-tube 303, and then be atomized by the atomizing nozzle 311 and sprayed onto the patient's calf, thereby disinfecting or applying medicine to the patient's calf wound. The operation process is simple and convenient, which greatly saves the time for disinfection or applying medicine.

[0052] When the area of ​​the calf wound is large, the electric push rod 308 is started, and the extension of the output end of the electric push rod 308 will drive the box 309 to rise. The movement of the square frame 309 will drive the push plate 310 to move. The movement of the push plate 310 will drive the mounting plate 301 to slide along the arc surface of the limiting rod 313 and the inner wall of the vertical frame 2. The sliding of the card frame 302 with the help of the mounting plate 301 will drive the C-shaped tube 303 to slide. The sliding of the C-shaped tube 303 will drive the atomizing nozzle 311 to move synchronously, thereby adjusting the spraying position of the atomizing nozzle 311, which is convenient for rapid disinfection or medication of patients with large-area wounds.

[0053] During the disinfection or medication process, the disinfectant or medicine will flow along the patient's legs to the top of the waste liquid tank 320. At this time, the baffle ring 321 can prevent the disinfectant or medicine from flowing to the ground. Moreover, since the baffle ring 321 is made of rubber, it can also prevent the baffle ring 321 from causing discomfort to the patient when the patient steps on the baffle ring 321. After that, the disinfectant or medicine will flow through the water permeable hole 322 into the waste liquid tank 320. The water permeable hole 322 can prevent larger foreign objects from entering the waste liquid tank 320. At the same time, it can also increase the friction on the upper surface of the waste liquid tank 320 to prevent the patient from slipping.

[0054] During the process of disinfecting or applying medicine to the patient, when the electric push rod 308 fails, the mounting plate 301 is manually pulled upward to disengage the mounting plate 301 from the push plate 310. Then, the mounting plate 301 can be further pulled upward to adjust the height of the atomizing nozzle 311. When the atomizing nozzle 311 needs to be moved downward, the push plate 310 is first pulled away from the vertical frame 2 to move the push plate 310 away from under the mounting plate 301. Then, the mounting plate 301 can be moved downward to adjust the position of the atomizing nozzle 311, thereby improving the reliability of the auxiliary device.

[0055] In addition, a flushing tank can be added. The liquid contained in the flushing tank is used to flush the pipeline and the atomizing nozzle 311. The flushing tank is arranged in parallel with the bottle body storing the disinfectant or liquid medicine, and is connected to the delivery pipe 306 through a branch pipe and a valve. After the disinfection work or each drug application process is completed, the flushing tank or bottle body is connected by switching the valve.

[0056] When the height of the support plate 43 needs to be adjusted during disinfection or application of medicine to patients of different sizes, the bent plate 42 is first pulled upward, and the bent plate 42 will drive the H-shaped plate 41 to slide. The square rod 44 slides with the help of the H-shaped plate 41 to drive the inserting plate 45 to slide. When the baffle contacts the top of the inner wall of the insertion hole 46, the inserting plate 45 can be pulled along the surface of the square rod 44 in the direction away from the vertical frame 2, so that the inserting plate 45 slides out from the inner wall of the insertion hole 46. Then, the H-shaped plate 41 is slid along the surface of the vertical frame 2 with the help of the bent plate 42 to adjust the height of the support plate 43. After adjusting to a suitable position, the inserting plate 45 is aligned with the insertion hole 46, and then the inserting plate 45 is slid in the opposite direction. When the inserting plate 45 passes through the insertion hole 46, the bent plate 42 is released. At this time, the inserting plate 45 is The influence of its own gravity will cause it to slide downward a distance, so the triangular protrusion on the surface of the insert plate 45 will contact the vertical frame 2, thereby preventing the insert plate 45 from sliding out of the inner wall of the socket 46, thereby improving the stability of the support plate 43. By adjusting the support plate 43 to different heights, patients of different body shapes can be lifted more comfortably. The inclined rod 47 has the effect of increasing the strength of the bending plate 42. When the output end of the electric push rod 308 is over-extended, the square frame 309 will abut against the lower surface of the H-shaped plate 41. Since the position of the H-shaped plate 41 is restricted, the H-shaped plate can prevent the square frame 309 from continuing to slide, thereby limiting the stroke of the electric push rod 308, thereby preventing the mounting plate 301 from abutting the patient's thigh, thereby improving the safety of the auxiliary device.

[0057] When the output end of the electric push rod 308 is extended, the C-shaped tube 303 will pull the conveying tube 306. At this time, the conveying tube 306 will squeeze the roller 53, so that the roller 53 drives the circular plate 52 to slide upward along the inner wall of the bar frame 51. The sliding of the circular plate 52 will squeeze the transmission plate 55, and the sliding of the transmission plate 55 will squeeze the second spring 56, so that the second spring 56 is in a compressed state. Since the two groups of rollers 53 on both sides of the vertical frame 2 are close to each other, the conveying tube 306 can be pulled upward normally. When the output end of the electric push rod 308 is retracted, the conveying tube 306 no longer squeezes the roller 53, and the circular plate 5 Under the influence of its own gravity, the roller 53 will slide in the opposite direction. At this time, the roller 53 will squeeze the delivery tube 306, thereby tightening the delivery tube 306 to prevent the delivery tube 306 from being loose and hanging on the ground, causing the delivery tube 306 to be stepped on and damaged, affecting the next use. During the process of the roller 53 tilting and sliding downward, the second spring 56 will continue to stretch. The transmission plate 55 will accelerate the sliding speed of the circular plate 52 with the help of the tension of the second spring 56, so that the circular plate 52 can be quickly reset. At the same time, it can also increase the squeezing force of the roller 53 on the delivery tube 306 to ensure that the delivery tube 306 is tightened.
