Description

Technical Field

[0001] This invention relates to the field of limb protection technology, specifically to a limb protection device for pediatric surgical clinical use. Background Technology

[0002] Pediatric surgery is an emerging clinical discipline that primarily studies pediatric diseases requiring surgical treatment. It is generally divided into specialized departments such as neonatal surgery, general pediatric surgery, pediatric cardiothoracic surgery, pediatric urology, pediatric neurosurgery, and pediatric otolaryngology. Because some children may resist examinations, be afraid of doctors, or struggle or move around due to discomfort, limb protection devices are needed to restrain and position the child during the diagnostic process in pediatric surgery to facilitate the doctor's examination.

[0003] Existing pediatric surgical limb protection devices typically use clamps to fix children's limbs. However, due to the different body sizes of children, the position of the clamps needs to be adjusted when fixing children. The adjustment of the clamp position of existing limb protection devices is relatively troublesome. In addition, when fixing children with clamps, one hand is needed to restrain the child's limb, move the child's limb to the clamp position, and the other hand is needed to fix the child's limb, which is quite inconvenient to use. Summary of the Invention

[0004] To overcome the aforementioned technical problems, the present invention aims to provide a limb protection device for pediatric surgical clinical use. A limiting airbag is fixedly connected to the device via a connecting seat, allowing two splints to be placed around the child's limb. The limiting airbag can then be inflated to surround the child's limb. After the child lies on the bed, the base can be fixed to the bed using a magnet. Adjusting the position of the protection module is relatively simple, and fixing it is also relatively easy. It does not require controlling the child's limb and is therefore convenient to use.

[0005] The objective of this invention can be achieved through the following technical solutions:

[0006] A pediatric surgical limb protection device includes a bed frame. Several protection modules are arranged on the top surface of the bed frame. Each protection module includes a connecting base. A connecting plate is fixedly connected to the bottom surface of the connecting base. A base is provided on the bottom surface of the connecting plate. A magnet block is fixedly connected to the bottom surface of the base, contacting the top surface of the bed frame. Fixing seats are fixedly connected to both sides of the top surface of the connecting base. Clamping plates are rotatably connected to the inner side of each fixing seat. A limiting airbag is fixedly connected to the top side of the connecting base and is connected to the two clamping plates. The interior of the limiting airbag communicates with the interior of the connecting base. The device allows the two clamping plates to be enclosed around the child's limb. The limiting airbag can then be inflated to limit the limb's position. The airbag surrounds the child's limbs, thus securing the protective module to the child's limbs. The child can then lie on the bed, where the protective module is attached to the bed by magnets, thus securing the child's limbs. The protective module can be moved directly on the bed, making adjustment relatively simple. Alternatively, the splint can be placed around the child's limbs first, and then secured by the limiting airbag. The fixation is simple and does not require controlling the child's limbs, making it convenient to use. The limiting airbag allows for soft contact with the child's limbs, minimizing discomfort. Furthermore, the limiting airbag can secure the limbs of children of different body types.

[0007] Furthermore, the clamp is fixedly connected to a frame on one side of its bottom. Two connecting grooves are formed on the top surface of the connecting seat on one side of the frame. A plug block is slidably connected to the inner side of the connecting groove and to the inner side of the adjacent frame. A piston groove is formed on one side of the connecting seat corresponding to the two connecting grooves. The center of the inner side of the piston groove communicates with the interior of the connecting seat. A stop rod is fixedly connected to the bottom surface of the plug block and slidably connected to the inner side of the connecting groove, with the bottom end of the stop rod extending into the piston groove. Piston blocks that contact the bottom ends of adjacent stop rods are slidably connected to the inner sides of both ends of the piston groove. When the limiting airbag is inflated, the gas in the connecting seat can enter the piston groove through the middle position of the piston groove. At this time, the gas can compress the piston block. After the clamp is closed, the piston block can insert the plug block into the frame through the stop rod, thereby further fixing the clamp and improving the stability of fixing the child's limbs.

[0008] Furthermore, the bottom end of the insert block is fixedly connected to a reset spring. When the limiting airbag deflates, the gas in the piston groove no longer squeezes the piston block. Under the action of the reset spring, the insert block can slide into the connecting groove and separate from the insert frame. At this time, the clamp can rotate arbitrarily, and then the child's limb can be removed from the protection module. Releasing the child's limb is relatively simple and convenient to use.

[0009] Furthermore, both of the two insert frames have arc-shaped blocks fixedly connected to their bottom opposite surfaces. When the clamping plates are open, if the connecting seat and the limiting airbag are inflated, the insert block can rest against the arc-shaped block. After the limiting airbag is fully opened, the insert block can first rest against the arc-shaped block, and then be inserted into the insert frame after the two clamping plates are closed. This ensures that the insert block and the insert frame can be smoothly connected.

[0010] Furthermore, the base has a fixed top surface with a limiting frame that contacts the side of the connecting plate, and the inner side of the limiting frame contacts the inner side of the connecting seat. The connecting plate has a fixed connecting seat on the side of the opening of the limiting frame. The inner side of the connecting seat has four equidistant annular connecting slots. The connecting slot at the top of the connecting seat communicates with the interior of the connecting seat, and the connecting slot on one side of the connecting seat communicates with the interior of the connecting plate. A connecting block is rotatably connected inside the connecting seat. An adjusting block is rotatably connected to the connecting block and fixedly connected to the connecting block. The connecting block can be rotated through the adjusting block, allowing air to be inflated into the limiting airbag. The connecting block can also be rotated to separate the connecting block from the connecting slots, thereby isolating the limiting airbag from the outside. The connecting slots at the bottom and on the other side are connected to the outside. The connecting block can be used to connect the top and the connecting slot on the other side, thereby deflating the limiting airbag.

[0011] Furthermore, an inflatable bladder is fixedly connected to the bottom surface of the connecting plate, and the interior of the inflatable bladder is connected to the interior of the connecting plate. The bottom surface of the inflatable bladder at its center is fixedly connected to the inner bottom surface of the base. A second return spring, which is fixedly connected to the bottom surface of the connecting plate, is fixedly connected to the inner bottom surface of the inflatable bladder. After the top is connected to the connecting groove on one side through the connecting block, the connecting plate can be connected to the interior of the connecting seat, thereby connecting the limiting airbag and the inflatable bladder. At this time, under the action of the second return spring, the inflatable bladder can be opened, thereby drawing the gas in the limiting airbag into the connecting seat. The gas in the connecting seat can pass through the connecting block into the connecting plate, thereby entering the inflatable bladder, thereby deflating the limiting airbag. The inflatable bladder can also be squeezed to squeeze the gas in the inflatable bladder into the limiting airbag, thus inflating the limiting airbag. The connecting block can also isolate the inflatable bladder from the outside world. Inflating the limiting airbag is relatively simple, does not require setting up an inflation source, and is easy to use.

[0012] Furthermore, a soft pad is fixedly connected to the top surface of the bed, and support blocks are provided on both sides of the top surface of the bed corresponding to the protection module. Children can lie on the soft pad, and the support blocks can support the children's limbs to avoid excessive discomfort caused by excessive limb suspension.

[0013] Furthermore, the connecting base has connecting frames fixedly connected to the top of both sides, and the top surface of the soft pad is provided with a limiting strap. One end of the limiting strap is slidably inserted into the side of the adjacent connecting frame, so that two protective modules can be set on both sides of the child's body. Then the limiting strap is inserted into the connecting frame, so that the protective modules can be fixed to the child's torso through the limiting strap.

[0014] The beneficial effects of this invention are:

[0015] 1. By connecting the limiting airbag to the connecting seat, the protection module can be directly removed from the bed frame. Then, the two splints are placed around the child's limbs, and the limiting airbag can be inflated to surround the child's limbs, thus fixing the protection module to the child's limbs. The child can then lie on the bed frame, and the base is fixed to the bed frame by the magnet, thereby fixing the child's limbs. The protection module can be moved directly on the bed frame, and adjusting the position of the protection module is relatively simple. The splints can be placed around the child's limbs first, and then fixed by the limiting airbag. The fixation is simple and does not require controlling the child's limbs, making it convenient to use.

[0016] 2. A piston block is slidably connected to the piston groove. When the limiting airbag is inflated, the gas can enter the piston groove from the middle position, thereby squeezing the piston block. After the clamp is closed, the piston block can push the insert block into the insert frame through the abutment rod, thereby limiting the position of the clamp and improving the stability of fixing the child's limb.

[0017] 3. A connecting block is rotatably connected inside the connecting seat. The connecting plate and the connecting seat can be connected through the connecting block, thereby connecting the inflatable airbag and the limiting airbag. The inflatable airbag can be squeezed to contract, sending the gas inside the inflatable airbag into the limiting airbag, thus inflating the limiting airbag and fixing it to the child's limb. Then, the connecting block can be rotated to isolate both the inflatable airbag and the limiting airbag from the outside, thereby connecting the connecting plate to the base and maintaining the inflated limiting airbag. Inflating the limiting airbag is relatively simple, does not require an inflation source, and is easy to use. Attached Figure Description

Detailed Implementation

[0028] The technical solutions of the present invention will be clearly and completely described below with reference to the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0029] Please see Figure 1-8As shown, a pediatric surgical limb protection device includes a bed 100. Several protection modules 200 are arranged on the top surface of the bed 100. Each protection module 200 includes a connecting seat 210. A connecting plate 230 is fixedly connected to the bottom surface of the connecting seat 210. A base 220 is arranged on the bottom surface of the connecting plate 230. A magnet 222, which contacts the top surface of the bed 100, is fixedly connected to the bottom surface of the base 220. Fixing seats 212 are fixedly connected to both sides of the top surface of the connecting seat 210. Clamping plates 240 are rotatably connected to the inner side of the fixing seats 212. A limiting airbag 211, which is fixedly connected to both clamping plates 240, is fixedly connected to the top side of the connecting seat 210. The interior of the limiting airbag 211 communicates with the interior of the connecting seat 210, allowing the two clamping plates 240 to be wrapped around the child's limb. Then, the limiting airbag 211 can be used to... 1. Inflate the airbag 211 so that it surrounds the child's limbs, thereby fixing the protection module 200 to the child's limbs. Then, the child can lie on the bed 100 and be attached to the bed 100 by the magnet 222, thus fixing the protection module 200 to the bed 100 and fixing the child's limbs. The protection module 200 can be moved directly on the bed 100, and adjusting the position of the protection module 200 is relatively simple. The splint 240 can be surrounded on the child's limbs first, and then fixed by the limiting airbag 211. The fixation is relatively simple and does not require controlling the child's limbs, making it convenient to use. The limiting airbag 211 can make soft contact with the child's limbs, which is conducive to preventing discomfort for the child. At the same time, the limiting airbag 211 can fix the limbs of children of different body types.

[0030] A frame 241 is fixedly connected to one bottom side of the clamping plate 240. Two connecting grooves are formed on the top surface of the connecting seat 210 on one side of the frame 241. A block 215, which is slidably connected to the inner side of the adjacent frame 241, is slidably connected to the inner side of the connecting groove. A piston groove is formed on one side of the connecting seat 210 corresponding to the two connecting grooves. The center of the inner side of the piston groove communicates with the interior of the connecting seat 210. A stop rod 213, which is slidably connected to the inner side of the connecting groove, is fixedly connected to the bottom surface of the block 215, and the bottom end of the stop rod 213 extends into the piston groove. Inside, piston blocks 216 that slidably connect to the bottom of adjacent abutment rods 213 are slidably connected to the inner sides of both ends of the piston groove. When the limiting airbag 211 is inflated, the gas in the connecting seat 210 can enter the piston groove through the middle position of the piston groove. At this time, the gas can compress the piston blocks 216. After the clamping plate 240 is closed, the piston blocks 216 can insert the insert block 215 into the insert frame 241 through the abutment rod 213, thereby further fixing the clamping plate 240 and improving the stability of fixing the child's limbs.

[0031] The bottom end of the insert 215 is fixedly connected to the return spring 214. When the limiting airbag 211 deflates, the gas in the piston groove no longer squeezes the piston block 216. Under the action of the return spring 214, the insert 215 can slide into the connecting groove and disengage from the insert frame 241. At this time, the clamp 240 can rotate freely, and then the child's limb can be removed from the protection module 200. Releasing the child's limb is relatively simple and easy to use.

[0032] Both insert frames 241 have arc-shaped blocks 242 fixedly connected to their bottom opposite sides. When the clamping plate 240 is open, if the connecting seat 210 and the limiting airbag 211 are inflated, the insert block 215 can be pressed against the arc-shaped block 242. After the limiting airbag 211 is fully opened, the insert block 215 can first press against the arc-shaped block 242. After the two clamping plates 240 are closed, it can be inserted into the insert frame 241. This ensures that the insert block 215 and the insert frame 241 can be smoothly connected.

[0033] A limiting frame 221 is fixedly connected to the top surface of the base 220, which contacts the side of the connecting plate 230. The inner side of the limiting frame 221 contacts the inner side of the connecting seat 210. A connecting seat 250 is fixedly connected to the side of the connecting plate 230 located on the side of the opening of the limiting frame 221. Four connecting slots 253 are equidistantly arranged in a ring on the inner side of the connecting seat 250. The connecting slot 253 located at the top of the connecting seat 250 communicates with the interior of the connecting seat 210, and the connecting slot 253 located on one side of the connecting seat 250 communicates with the interior of the connecting plate 230. A connecting block is rotatably connected inside the connecting seat 250. 251, The inner side of the connecting seat 250 is rotatably connected to an adjusting block 252 which is fixedly connected to the connecting block 251. The connecting block 251 can be rotated through the adjusting block 252, and the limiting airbag 211 can be inflated through the connecting block 251. The connecting block 251 can also be rotated to separate the connecting block 251 from the connecting groove 253, thereby isolating the limiting airbag 211 from the outside. The connecting groove 253 located at the bottom and on the other side are connected to the outside. The top can be connected to the connecting groove 253 on the other side through the connecting block 251, thereby deflating the limiting airbag 211.

[0034] An inflatable bladder 231 is fixedly connected to the bottom surface of the connecting plate 230, and the interior of the inflatable bladder 231 communicates with the interior of the connecting plate 230. The bottom surface of the inflatable bladder 231 at its center is fixedly connected to the inner bottom surface of the base 220. A return spring 233, which is fixedly connected to the bottom surface of the inflatable bladder 231 and is also fixedly connected to the bottom surface of the connecting plate 230, is fixedly connected to the bottom surface of the connecting plate 230. After the top is connected to the connecting groove 253 on one side through the connecting block 251, the connecting plate 230 can communicate with the interior of the connecting seat 210, thereby connecting the limiting airbag 211 with the inflatable bladder 231. At this time, under the action of the return spring 233, it is possible to... Inflating the airbag 231 allows the gas inside the limiting airbag 211 to be drawn into the connecting seat 210. The gas inside the connecting seat 210 can pass through the connecting block 251 into the connecting plate 230, and then into the airbag 231, thereby deflating the limiting airbag 211. The airbag 231 can also be squeezed to compress the gas inside into the limiting airbag 211, thus inflating the limiting airbag 211. The connecting block 251 can also isolate the airbag 231 from the outside environment. Inflating the limiting airbag 211 is relatively simple, does not require an inflation source, and is easy to use.

[0035] A soft pad 110 is fixedly connected to the top surface of the bed frame 100. Support blocks 120 are provided on both sides of the top surface of the bed frame 100 corresponding to the protection module 200. Children can lie on the soft pad 110, and the support blocks 120 can support the child's limbs to avoid excessive discomfort caused by the child's limbs being suspended in the air.

[0036] Connecting brackets 260 are fixedly connected to the top of both sides of the connecting base 210. A limiting strap 300 is provided on the top surface of the soft pad 110. One end of the limiting strap 300 is slidably inserted into the side of the adjacent connecting bracket 260. Two protective modules 200 can be set on both sides of the child's body. Then the limiting strap 300 is threaded into the connecting bracket 260, so that the protective modules 200 are fixed to the child's torso through the limiting strap 300.

[0037] Working principle: In use, rotating the adjusting block 252 connects the connecting seat 210 and the connecting plate 230 through the connecting block 251, thereby connecting the inflatable bladder 231 and the limiting airbag 211. At this time, under the action of the second return spring 233, the inflatable bladder 231 can be opened, drawing the gas from the limiting airbag 211 into the connecting seat 210. The gas in the connecting seat 210 can pass through the connecting block 251 into the connecting plate 230, and then into the inflatable bladder 231. At this time, the two clamping plates 240 can open and rotate freely, allowing the portion of the limiting airbag 211 located on the connecting seat 210 to be placed on the child's limb. Then, the inflatable bladder 231 is compressed, inflating the gas from the inflatable bladder 231 into the limiting airbag 211. The limiting airbag 211 is inflated, which allows the splint 240 to rotate and surround the child's limb, thus enveloping the child's limb. Alternatively, the two splints 240 can be directly surrounded by the child's limb. Then, the limiting airbag 211 is inflated by the inflation bag 231, so that the limiting airbag 211 surrounds the child's limb. When the inflation bag 231 inflates the limiting airbag 211, the gas in the connecting seat 210 can enter the piston groove through the middle position of the piston groove. At this time, the gas can compress the piston block 216. After the splint 240 is closed, the piston block 216 can insert the insert block 215 into the insert frame 241 through the push rod 213, thereby further fixing the splint 240.

[0038] After the limiting airbag 211 surrounds the child's limbs, the adjusting block 252 can be rotated to drive the connecting block 251 to rotate, so that the connecting groove 253 is misaligned with the connecting block 251, thereby isolating both the inflatable airbag 231 and the limiting airbag 211 from the outside world, allowing the connecting plate 230 and the connecting seat 210 to be inserted into the limiting frame 221. Then, the child can lie on the soft pad 110 of the bed 100, and the protective module 200 can be placed on the bed 100, so that the magnet block 222 is attracted to the bed 100, thereby fixing the protective module 200 on the bed 100. The position of the protective module 200 can be moved directly on the bed 100 to adapt to different children's body shapes and postures during examinations. Two protective modules 200 can be set on both sides of the child's body, and then the limiting strap 300 is threaded through the connecting frame 260, so that the protective module 200 is fixed to the child's torso through the limiting strap 300.

[0039] After the inspection is completed, the connecting block 251 can be rotated to connect the limiting airbag 211 with the outside world, while keeping the inflatable airbag 231 isolated from the outside world. At this time, the limiting airbag 211 can release air to the outside world through the connecting seat 210 and the connecting block 251, causing the limiting airbag 211 to deflate and no longer support and limit the clamping plate 240. This also prevents the gas in the piston groove from compressing the piston block 216. Then, under the action of the return spring 214, the insert block 215 can slide into the connecting groove and disengage from the insert frame 241. At this point, the clamp 240 can rotate freely, and the child's limb can be removed from the protective module 200. Then, the connecting block 251 can be rotated to allow the airbag 231 to connect with the outside through the connecting block 251. Under the action of the reset spring 233, the airbag 231 draws in outside air, causing the airbag 231 to expand and inflate. Then, the connecting block 251 can be rotated to connect the airbag 231 with the limiting airbag 211, so that the child's limb can be fixed again.
