Description

Technical Field

[0001] The present invention relates to the technical field of surgical nursing, and in particular to a restraint device for surgical nursing that is easy to use. Background Art

[0002] During the postoperative rehabilitation stage, patients who undergo clinical surgical specialist surgeries often need to use professional limb restraint devices to ensure treatment safety and promote functional recovery. Taking orthopedic, neurosurgery or vascular surgery involving lower limbs as an example, patients may experience unconscious agitation due to residual anesthesia effects, pain stimulation or confusion, or need to maintain a specific body position due to treatment needs. At this time, the scientific application of restraint devices can effectively prevent complications such as incision dehiscence, drainage tube detachment or implant displacement caused by involuntary movement, reduce abnormal joint activity, and reduce postoperative pain, creating favorable conditions for drug analgesia.

[0003] Traditional restraint devices usually use an annular fixing device to be put on the patient's limbs, or directly use straps to fix the patient's limbs. This overly tight fixation may compress blood vessels and nerves, causing distal limb ischemia, and the patient's limbs may subconsciously rotate and cause injury. At the same time, when using it, if the patient's legs are supported, both sides of the legs need to be padded to prevent the patient's legs from flipping to the sides. This requires carrying extra towels or sponges and other fillers, which is very inconvenient. Therefore, a restraint device for surgical care that is easy to use is proposed. Summary of the invention

[0004] The present invention aims at the deficiencies in the prior art and provides the following technical solutions: A surgical nursing restraint device that is easy to use, comprising a pair of main body and connecting pieces, and further comprising: A support assembly installed inside the main board body to limit the positions of both sides of the legs; The binding components are arranged on both sides of the main board body and are used to bind and fix the legs to the main board body; A release assembly, which is disposed inside the main body and is used to unlock the locking parts of the support assembly and the restraint assembly; Wherein, the support assembly includes a support airbag fixedly connected to the inside of the main board body, one end of the support airbag located inside the main board body is fixedly connected to an adjustment airbag, and a pair of adjustment airbags are fixedly connected to a compression plate on one side close to each other; The binding assembly comprises two sets of sliding seats slidably connected to the main board body and a pair of limiting rods fixedly connected to the main board body, and a binding belt is installed between the pair of sliding seats.

[0005] Preferably, the connecting piece is distributed in the middle of a pair of main board bodies and is hinged to the pair of main board bodies, the supporting airbag penetrates the top of the main board body, and the side of the supporting airbag facing the middle is arc-shaped, and after compression, the adjusting airbag transports air into the interior of the supporting airbag to expand the supporting airbag, and a plurality of holes are arranged in the middle of the adjusting airbag.

[0006] Preferably, the extrusion plate is slidably connected inside the main body, support rods are provided on the sides of the extrusion plates close to each other, and the ends of the support rods are fixedly connected to the first elastic member, and the ends of a pair of support rods supporting the airbag in the middle are respectively fixedly connected to hand rods.

[0007] Preferably, the sliding seat is slidably connected to the limiting rod, one end of the restraining belt is rotatably connected to the sliding seat, and the other end is provided with a Velcro, which surrounds the middle part of the sliding seat through the Velcro; The restraining assembly comprises a movable baffle slidably connected inside the main board body, a rectangular fixed block corresponding to the sliding seat is slidably connected to the middle of the movable baffle, and a second elastic member is fixedly connected to the side of the movable baffle.

[0008] Preferably, the movable baffle is distributed between a pair of limiting rods, a friction layer is provided on the side of the limiting rod facing the movable baffle, an opening is provided at one end of the sliding seat facing the movable baffle, and the rectangular fixed block is slidably connected inside the sliding seat.

[0009] Preferably, the second elastic member is located on a side of the movable baffle close to the limit rod and is fixedly connected to the main body. A plurality of push rods are provided on the side of the movable baffle toward the middle, which can contact the extrusion plate through the hole in the middle of the airbag when adjusting the airbag compression.

[0010] Preferably, when the first elastic member pushes the extrusion plate to move to both sides, the extrusion plate will squeeze the adjustment airbag to shrink, so that the air inside the adjustment airbag is transported into the support airbag to expand the support airbag. While the adjustment airbag shrinks, it will squeeze the movable baffle to move, so that the movable baffle pushes the rectangular fixed block to squeeze and contact the friction layer of the limit rod.

[0011] Preferably, the release assembly includes a pressing rod slidably connected to the main board body, a pair of arched blocks are arranged on the pressing rod, a pair of third elastic members are arranged on the side of the arched block facing the connecting member, and inclined locking blocks are arranged on both sides of the arched block.

[0012] Preferably, one end of the pressing rod penetrates one end of the main board body away from the connecting piece, the pressing rod and the bow-shaped clamping block are distributed in the middle of a pair of extrusion plates, the bow-shaped clamping block is slidably connected to the main board body, one end of the third elastic member is fixedly connected to the main board body, and the two groups of inclined locking blocks are respectively fixed on one side of a pair of extrusion plates facing the middle.

[0013] Preferably, when the hand pull rod drives the extrusion plate to move toward the middle, the inclined locking block will interfere with the bow-shaped clamping block and move the bow-shaped clamping block by squeezing the bow-shaped clamping block through the inclined surface. After the bow-shaped clamping block moves to be misaligned with the inclined locking block, it is pushed by the third elastic member to reset and engage with the inclined locking block.

[0014] Beneficial effects of the present invention: The present invention facilitates supporting the patient's legs by arranging the coordination of structures such as the main body and the support assembly. By adjusting the contraction of the airbag, air is supplied to the support airbag to expand the support airbag. After the support airbag expands, it supports both sides of the patient's legs, ensuring comfort while preventing the patient from twisting his legs, thereby ensuring that the patient's legs cannot rotate and will be blocked by the support airbag when rotating. The present invention facilitates stable fixation of the patient's legs by arranging the cooperation of the restraining assembly and the supporting assembly, and pushes the extrusion plate to move toward both sides through the first elastic member, so that the extrusion plate squeezes the adjustment airbag, and the air inside the adjustment airbag is transported to the inside of the supporting airbag, so that the supporting airbag expands to support and limit both sides of the patient's legs. Compared with the traditional restraint belt, after restraining the patient, in order to prevent the patient's limbs from rotating, additional cloth or other objects are used to fill and support both sides of the patient's legs. The expansion of the airbag is faster and more convenient. Only the pressing rod needs to be pressed to release the limit of the extrusion plate to expand the supporting airbag. It is convenient to use and does not need to carry extra fillers. The present invention facilitates the control of locking and releasing of the support assembly and the restraint assembly by setting up the cooperation of structures such as the release assembly and the extrusion plate. When in use, the lock of the arc-shaped clamping block on the inclined locking block can be released by simply pressing the pressing rod, so that the extrusion plate can squeeze the adjustment airbag to contract and expand the support airbag, and at the same time squeeze the movable baffle and the rectangular fixing block to fix the sliding seat. The entire fixing operation only requires adjusting the restraining belt and pressing the pressing rod to release the compressed elastic member to achieve the expansion of the support airbag and the fixation of the sliding seat, which is very convenient and fast.

DETAILED DESCRIPTION

[0017] In order to make the purpose, technical solution and advantages of the present invention more clear, the present invention is further described in detail below. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0018] like Figures 1 to 7 As shown, the present invention provides a surgical nursing restraint device that is easy to use, including a pair of main body 1 and a connecting member 2, and also includes: A support assembly 3, which is installed inside the main board body 1 and is used to limit the two sides of the leg; The binding components 4 are arranged on both sides of the main board body 1 and are used to bind and fix the legs to the main board body 1; A release assembly 5, which is arranged inside the main body 1 and is used to unlock the locking parts of the support assembly 3 and the restraint assembly 4; The support assembly 3 includes a support airbag 301 fixedly connected to the inside of the main board body 1, one end of the support airbag 301 located inside the main board body 1 is fixedly connected to an adjustment airbag 302, and a pair of adjustment airbags 302 are fixedly connected to a pressing plate 303 on one side close to each other; The restraint assembly 4 includes two sets of sliding seats 401 slidably connected to the main board body 1 and a pair of limiting rods 406 fixedly connected to the main board body 1 . A restraint belt 402 is installed between the pair of sliding seats 401 .

[0019] The above scheme is adopted: the arch-shaped clamping block 502 is driven to move by pressing the pressing rod 501 at the end of the main body 1, so that the arch-shaped clamping block 502 releases the clamping connection with the inclined locking block 504, and the first elastic member 304 pushes the extrusion plate 303 to move toward both sides, so that the extrusion plate 303 squeezes the adjustment airbag 302, and the air inside the adjustment airbag 302 is transported to the inside of the support airbag 301, so that the support airbag 301 expands to support and limit both sides of the patient's legs. When the extrusion plate 303 squeezes the adjustment airbag 302 to contract, the movable baffle plate 403 is squeezed to move to both sides through the push rod, so that the movable baffle plate 403 squeezes the rectangular fixed block 404 and contacts the limit rod 406, and then the sliding seat 401 is fixed by the rectangular fixed block 404.

[0020] like Figures 2 to 5 As shown, the connecting member 2 is distributed in the middle of a pair of main board bodies 1 and is hinged with the pair of main board bodies 1, the supporting airbag 301 penetrates the top of the main board body 1, and the side of the supporting airbag 301 facing the middle is arc-shaped, and after the adjusting airbag 302 is compressed again, the air is transported into the supporting airbag 301 to expand the supporting airbag 301, and a plurality of holes are arranged in the middle of the adjusting airbag 302; the extrusion plate 303 is slidably connected to the inside of the main board body 1, and support rods are arranged on the sides of the extrusion plates 303 close to each other, and the ends of the support rods are fixedly connected to the first elastic member 304, and at the same time, the ends of a pair of support rods located in the middle of the supporting airbag 301 are respectively fixedly connected to hand pull rods 305.

[0021] The above scheme is adopted: by setting up a support component 3, the support airbag 301 is expanded to support both sides of the patient's legs, so as to ensure comfort while preventing the patient from twisting his legs. The setting of the adjustment airbag 302 and the extrusion plate 303 is used to control the expansion and contraction of the support airbag 301. The adjustment airbag 302 is pulled to unfold by the extrusion plate 303, and the adjustment airbag 302 will suck out the air inside the support airbag 301, so that the support airbag 301 will shrink, which is convenient for storage, and at the same time prevents the support airbag 301 from always remaining expanded and being damaged by external influences. On the contrary, the adjustment airbag 302 shrinks and supplies air to the support airbag 301 to expand the support airbag 301. The extrusion plate 303 and the first elastic member 304 are arranged to facilitate the overall contraction of the adjustment airbag 302.

[0022] like Figures 3 to 7 As shown, the sliding seat 401 is slidably connected to the limiting rod 406, one end of the restraining belt 402 is rotatably connected to the sliding seat 401, and the other end is provided with a Velcro, which surrounds the middle part of the sliding seat 401 through the Velcro; The restraining assembly 4 includes a movable baffle 403 slidably connected inside the main body 1 , a rectangular fixing block 404 corresponding to the sliding seat 401 is slidably connected to the middle of the movable baffle 403 , and a second elastic member 405 is fixedly connected to the side of the movable baffle 403 .

[0023] The above scheme is adopted: by setting the restraint assembly 4 to fix the patient's legs, by setting the sliding seat 401 to adjust the position of the restraint belt 402 at will, so as to be suitable for different patients, and the movable baffle 403, the rectangular fixing block 404 and the limit rod 406 are set to fix the sliding seat 401; By providing a Velcro at one end of the restraint belt 402, the tightness of the restraint belt 402 can be adjusted by pushing the restraint belt 402, and the restraint belt 402 can be conveniently fixed.

[0024] like Figures 3 to 7 As shown, the movable baffle 403 is distributed in the middle of a pair of limit rods 406, a friction layer is provided on the side of the limit rod 406 facing the movable baffle 403, an opening is provided at one end of the sliding seat 401 facing the movable baffle 403, and a rectangular fixed block 404 is slidably connected inside the sliding seat 401; the second elastic member 405 is located on the side of the movable baffle 403 close to the limit rod 406 and is fixedly connected to the main board body 1, and a plurality of push rods are provided on the side of the movable baffle 403 facing the middle, and the push rods can contact the extrusion plate 303 from the hole in the middle of the adjustment airbag 302 when the adjustment airbag 302 is compressed.

[0025] The above solution is adopted: the friction layer arranged on the side of the limiting rod 406 abuts against the rectangular fixing block 404, so as to fix the rectangular fixing block 404, and at the same time, the opening opened on the side of the sliding seat 401 allows the rectangular fixing block 404 to slide inside the sliding seat 401, and then after the rectangular fixing block 404 is fixed, the sliding seat 401 can be fixed synchronously; The movable baffle 403 is provided to adjust the lateral position of the rectangular fixed block 404 to fix the sliding seat 401. The second elastic member 405 provided on the movable baffle 403 prevents the movable baffle 403 from squeezing the rectangular fixed block 404 and causing it to collide with the limiting rod 406 in a normal state. The top rod provided on the movable baffle 403 causes the movable baffle 403 to be squeezed by the squeezing plate 303, thereby pushing the rectangular fixed block 404 and causing it to collide with the limiting rod 406, so that the support airbag 301 expands to support the patient's legs while fixing the sliding seat 401.

[0026] like Figures 3 to 6 As shown, when the first elastic member 304 pushes the extrusion plate 303 to move to both sides, the extrusion plate 303 will squeeze the adjustment airbag 302 to contract, so that the air inside the adjustment airbag 302 is transported into the support airbag 301, causing the support airbag 301 to expand. While the adjustment airbag 302 contracts, it will squeeze the movable baffle 403 to move, causing the movable baffle 403 to push the rectangular fixed block 404 to squeeze and contact the friction layer of the limit rod 406.

[0027] The above scheme is adopted: when the first elastic member 304 pushes the extrusion plate 303 to move to both sides, the extrusion plate 303 will first squeeze the adjustment airbag 302 to contract, so that the air inside the adjustment airbag 302 is transported into the support airbag 301, so that the support airbag 301 expands, supports and fixes the patient's legs, and while the adjustment airbag 302 contracts, the extrusion plate 303 will contact the top rod of the movable baffle 403 to squeeze the movable baffle 403 to move to both sides, so that the movable baffle 403 pushes the rectangular fixed block 404 to squeeze and contact the friction layer of the limit rod 406.

[0028] like Figure 3 , Figure 4 and Figure 7 As shown, the release component 5 includes a pressing rod 501 that is slidably connected to the main board body 1, a pair of arched blocks 502 are arranged on the pressing rod 501, a pair of third elastic members 503 are arranged on the side of the arched block 502 facing the connecting member 2, and inclined locking blocks 504 are arranged on both sides of the arched block 502; one end of the pressing rod 501 penetrates the end of the main board body 1 away from the connecting member 2, the pressing rod 501 and the arched block 502 are distributed in the middle of a pair of extrusion plates 303, the arched block 502 is slidably connected to the main board body 1, one end of the third elastic member 503 is fixedly connected to the main board body 1, and two groups of inclined locking blocks 504 are respectively fixed on one side of a pair of extrusion plates 303 facing the middle.

[0029] The above scheme is adopted: by setting the release component 5, it is convenient to control the locking and releasing of the support component 3 and the restraint component 4, and the inclined locking block 504 set on the extrusion plate 303 is engaged with the arched clamping block 502, so as to lock the extrusion plate 303, thereby keeping the adjustment airbag 302 in an expanded state, while the support airbag 301 is in a contracted state, and the rectangular fixing block 404 inside the sliding seat 401 does not conflict with the limit rod 406, so that the sliding seat 401 can slide freely; One end of the pressing rod 501 is arranged to penetrate the side surface of the main body 1 , so that the pressing rod 501 can be directly pushed to drive the pressing rod 501 to move, thereby releasing the lock on the pressing plate 303 .

[0030] like Figures 2 to 4 As shown, when the hand pull rod 305 drives the extrusion plate 303 to move toward the middle, the inclined locking block 504 will interfere with the bow-shaped block 502 and move the bow-shaped block 502 by squeezing the bow-shaped block 502 through the inclined surface. After the bow-shaped block 502 moves to be misaligned with the inclined locking block 504, it is pushed by the third elastic member 503 to reset and engage with the inclined locking block 504.

[0031] The above scheme is adopted: by setting the release component 5, it is convenient to control the locking and releasing of the support component 3 and the restraint component 4, and the inclined locking block 504 set on the extrusion plate 303 is engaged with the arched clamping block 502, so as to lock the extrusion plate 303, thereby keeping the adjustment airbag 302 in an expanded state, while the support airbag 301 is in a contracted state, and the rectangular fixing block 404 inside the sliding seat 401 does not conflict with the limit rod 406, so that the sliding seat 401 can slide freely; One end of the pressing rod 501 is arranged to penetrate the side surface of the main body 1 , so that the pressing rod 501 can be directly pushed to drive the pressing rod 501 to move, thereby releasing the lock on the pressing plate 303 .

[0032] The working principle and use process of the present invention are as follows: when in use, after unfolding the main body 1, place the patient's leg joint on the main body 1 with the connecting piece 2 as the center, and then connect one end of the Velcro of the restraint belt 402 to the sliding seat 401 around, restrain the patient's leg on the inner side of the restraint belt 402, and then move the sliding seat 401 to a suitable position according to the actual situation, and then tighten the restraint belt 402; After the restraint belt 402 is tightened, the pressing rod 501 at the end of the main body 1 can be pressed to make the pressing rod 501 drive the arcuate clamping block 502 to move, so that the arcuate clamping block 502 releases the clamping connection with the inclined locking block 504, and then releases the locking of the extrusion plate 303. At this time, the first elastic member 304 in the compressed state will rebound to push the extrusion plate 303 to move toward both sides, so that the extrusion plate 303 squeezes the adjustment airbag 302, and the air inside the adjustment airbag 302 is transported to the inside of the support airbag 301, so that the support airbag 301 expands to support and limit both sides of the patient's legs. When the extrusion plate 303 squeezes the adjustment airbag 302 to contract, the movable baffle plate 403 is squeezed to move toward both sides through the push rod, so that the movable baffle plate 403 squeezes the rectangular fixed block 404 and contacts the limiting rod 406, and then the sliding seat 401 is fixed by the rectangular fixed block 404. In actual use, it is only necessary to adjust the sliding seat 401, then tighten the restraining belt 402, and finally press the pressing rod 501 to conveniently fix the patient's legs. Compared with traditional restraint methods, it is faster and more stable.

[0033] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit them.
