Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, in particular to a post-operative binding and fixation device for burn parts. Background Art

[0002] In burn and plastic surgery, patients' limbs need to be bandaged after surgery, and the bandaged area needs to be tightly fixed to prevent the bandage from loosening and bacteria from entering the wound, affecting the patient's postoperative wound healing. However, current plastic surgery hospitals do not have specific devices to fix patients' limbs after surgery. They simply use medical tape to tightly fix the bandaged gauze. This method of tightly binding patients' limbs with tape has many disadvantages. On the one hand, the patient's muscles are easily tensed or relaxed when using the limb, causing the tape to loosen, affecting the overall binding and fixation effect; on the other hand, it does not protect the affected area after surgery, and it is easy to accidentally touch the wound after surgery, causing secondary damage, and the practical effect is not good.

[0003] After searching, the patent with Chinese publication number CN215229222U discloses a postoperative binding and fixation device for burn parts, which is roughly described as including two groups of semicircular clamps that are docked together. The inner side of the clamp is fixedly connected to the protective plate, and the inner side of the protective plate is provided with an airbag. The two ends of the clamp are respectively fixedly connected to the first connecting block and the second connecting block. A screw is movably passed through the adjacent first connecting blocks. The outer end of the second connecting block is provided with a slot, and a rotating block is provided in the slot, and the rotating block is rotatably installed in the slot through a rotating shaft. The rotating blocks in the two relatively arranged groups of second connecting blocks are respectively fixedly connected to a threaded barrel and a fixed barrel. The threaded barrel is movably inserted into the fixed barrel, and a handle is provided on the outer side of the connecting end of the fixed barrel and the threaded barrel.

[0004] The above-mentioned existing technical solution can achieve the fixing effect by forming a complete annular structure through the docking and fixing of two sets of mating semicircular clamps, and at the same time protecting the patient's burn area through the protective plate and the airbag. However, when the two sets of clamps are docked and fixed, the air pressure in the airbag is too high and the patient may feel discomfort in the wound due to long-term use. At this time, the airbag can only be deflated by loosening the tightness between the two sets of clamps, which is inconvenient to adjust. Utility Model Content

[0005] The technical problem to be solved by the utility model is to overcome the deficiencies of the prior art and provide a postoperative binding and fixation device for burn parts, which can facilitate patients to adjust the air pressure in the airbag by themselves.

[0006] In order to solve the above technical problems, the technical solution adopted by the utility model is: to provide a postoperative binding and fixation device for burn parts, including a clamp assembly, wherein the clamp assembly has two, and the two clamp assemblies are assembled together symmetrically.

The connecting piece is arranged at the first end of the clamp, and the connecting piece is used to connect to the second end of the other clamp. The air pressure regulating device is connected to the airbag for regulating the air pressure in the airbag.

[0007] Furthermore, the connecting member includes a first connecting block, a second connecting block, a threaded rod and a nut, the first connecting block and the second connecting block are respectively connected to the first end of the clamp and the second end of the other clamp, the second connecting block is provided with a through hole, the threaded rod is fixedly connected to the first connecting block, and the nut is threadedly connected to the outside of the threaded rod; when the two clamp assemblies are assembled together in a centrally symmetrical manner, the second connecting block will be sleeved on the outside of the other threaded rod through the through hole, and be located between the other first connecting block and the nut.

[0008] Furthermore, a plurality of anti-slip stripes are provided on the outer peripheral side wall of the nut.

The device is suitable for patients of different body shapes. The device can be used together with a protective plate to protect the affected part bandaged after surgery, so as to prevent the patient from touching the wound in daily life. The affected part bandaged after surgery is tightly bound and fixed by arranging an air bag on the inner wall of the clamp for expansion.

DETAILED DESCRIPTION

[0021] The following is further described in detail through specific implementation methods:

[0022] See Figure 1 、 Figure 2 as well as Figure 3The present invention provides a postoperative fixation device for burn injuries, comprising a clamp assembly 1. The clamp assembly 1 comprises two clamp assemblies 1, which are centrally symmetrically assembled together. The clamp assembly 1 includes a clamp 11, a protective plate 12, an airbag 13, a connector 14, and an air pressure regulating device 15. The clamp 11, protective plate 12, and airbag 13 are all arc-shaped structures, with the protective plate 12 positioned between the clamp 11 and the airbag 13. The connector 14 is positioned at the first end of the clamp 11 and is configured to connect to the second end of the other clamp 11. The air pressure regulating device 15 is connected to the airbag 13 to regulate the air pressure within the airbag 13. During use, the two clamps 11 are detachably connected and positioned on the outside of the patient's limb. The distance between them is adjusted using the connector 14, and the clamp assemblies are then fixed so that they engage the patient's limb for installation. The clamp assembly 1 is suitable for use on patients of different body shapes, and in conjunction with the protective plate 12, it can protect the affected area after postoperative bandage. An air bag 13 is provided on the inner wall of the clamp 11 to expand and bind the affected part of the patient after surgery. Since the air bag 13 has a certain elasticity, it can bind the affected part while avoiding excessive squeezing of the affected part. When the air pressure in the air bag is at a high pressure for a long time and causes discomfort to the patient, the patient can adjust the air pressure in the air bag 13 through the air pressure regulating device 15, which is more applicable and more convenient.

[0023] To connect and lock the two clamps 11, the connector 14 includes a first connecting block 141, a second connecting block 142, a threaded rod 143, and a nut 144. The first connecting block 141 and the second connecting block 142 are connected to the first end of the clamp 11 and the second end of the other clamp 11, respectively. The second connecting block 142 has a through hole, the threaded rod 143 is fixedly connected to the first connecting block 141, and the nut 144 is threadedly connected to the outside of the threaded rod 143. When the two clamp assemblies 1 are assembled together in a centrally symmetrical manner, the second connecting block 142 is inserted through the through hole and is positioned outside the other threaded rod 143, between the other first connecting block 141 and the nut 144. In this embodiment, the connector 14 is provided in two sets, one at each end of the two clamps 11. During use, the nut 144 can be moved along the length of the threaded rod 143 by rotating it. At this time, since the second connecting block 142 is located between the first connecting block 141 and the nut 144, when the nut 144 moves, it will squeeze the second connecting block 142 toward the first connecting block 141 until the second connecting block 142 abuts the first connecting block 141. Since the two first connecting blocks 141 and the two second connecting blocks 142 are tangentially opposite to each other, the two clamps 11 can be assembled relative to each other. When the connectors 14 at both ends of the clamp 11 are connected, the two clamp assemblies 1 are symmetrically assembled and can be tightened to the affected area. To facilitate patient adjustment, a number of anti-slip stripes 1441 are provided on the outer side wall of the nut 144. By providing the anti-slip stripes 1441, the friction between the patient's hand and the nut 144 is increased when the patient rotates the nut 144, preventing the patient's hand from slipping when rotating the nut 144. When the two clamp assemblies 1 are aligned, the airbag 13 abuts the affected area. To increase the comfort of the affected area, a sponge layer (not shown) is provided on the outer wall of the airbag 13. The sponge layer can prevent the airbag 13 from directly contacting the affected area, making it relatively softer. At the same time, the clamp 11 and the protective plate 12 are both made of hollow plastic material. The hollow plastic structure design can make the overall structure lighter and more comfortable for patients to wear.

[0024] When a patient wears the device for a long time, the excessively high air pressure in the airbag 13 constantly abuts the affected area, which may cause discomfort in the affected area. In this case, the patient can adjust the air pressure in the airbag 13 through the air pressure regulating device 15, thereby reducing the air pressure in the airbag 13 and making the affected area more comfortable. To facilitate patient adjustment, in this embodiment, the air pressure regulating device 15 includes a piston cylinder 151, a piston 152, and a piston rod 153. The vent end of the piston cylinder 151 is connected to the airbag 13, and the piston 152 is sealingly and slidably connected to the piston cylinder 151. One end of the piston rod 153 is connected to the piston 152, and the other end of the piston rod 153 extends through the piston cylinder 151 away from the vent end and is threadedly connected to the piston cylinder 151. To facilitate communication between piston cylinder 151 and airbag 13, threaded rod 143 is designed as a hollow structure that runs through from top to bottom. Piston cylinder 151 is fixed to the end of threaded rod 143 away from first connecting block 141. The vent end of piston cylinder 151 is connected to the interior of threaded rod 143. The end of threaded rod 143 away from piston cylinder 151 is connected to airbag 13 via hose 2. Through this design, threaded rod 143 can be used to adjust the spacing between first connecting block 141 and second connecting block 142, and can also serve as a connecting tube to connect piston cylinder 151 to airbag 13, making the overall structure simpler and saving production costs. By threading piston rod 153 to piston cylinder 151, piston rod 153 is prevented from moving on its own, ensuring the stability of the air pressure in airbag 13. When adjustment is needed, it can be made by rotating piston rod 153. Specifically, a cylinder cap 1511 is provided at the end of piston cylinder 151 away from its vent end. Piston rod 153 passes through cylinder cap 1511 and is threadedly connected to it. To achieve a threaded connection between piston rod 153 and cylinder cover 1511, a threaded hole 15111 is provided on cylinder cover 1511, and the outer surface of piston rod 153 is provided with external threads that match threaded hole 15111. To facilitate the patient's rotation of piston rod 153, a knob 1531 is provided at the end of piston rod 153 away from piston 152. The patient can rotate piston rod 153 by rotating knob 1531, which is more labor-saving. Because piston 152 abuts the inner wall of piston cylinder 151, when piston rod 153 rotates, piston 152 generates a certain amount of friction with the inner wall of piston cylinder 151, which increases the difficulty of the patient rotating piston rod 153. Therefore, in this embodiment, piston rod 153 and piston 152 are designed to be rotatably connected. When the patient rotates the piston rod 153 , the end of the piston rod 153 close to the piston 152 will rotate at the same time, which reduces the difficulty of the patient rotating the piston rod 153 . At the same time, when the piston rod 153 moves, it will also push the piston 152 to move.The air pressure regulating device 15 allows the patient to easily adjust the air pressure within the airbag 13. When the air pressure in the airbag 13 is too high, squeezing the affected area too much, the patient simply rotates the knob 1531 to move the piston rod 153 away from the piston cylinder 151, and the piston 152 also moves with the piston rod 153, which is now in the deflated state. If the air pressure in the airbag 13 is too low, resulting in insufficient tightening, the patient simply rotates the knob 1531 to move the piston rod 153 toward the piston cylinder 151, and the piston 152 also moves with the piston rod 153, which is now in the inflated state. This design facilitates patient adjustment and enhances practicality.

It should be noted that those skilled in the art can make various modifications and improvements without departing from the structure of the present invention, and these modifications should also be considered within the scope of protection of the present invention. These modifications and improvements will not affect the effectiveness of the implementation of the present invention and the practicality of the present invention.
