Description

Technical Field

[0001] This invention relates to the field of medical dressing change assistance technology, specifically to an easily adjustable medical dressing change assistance device. Background Technology

[0002] With the continuous development of medical and nursing technology, open wound dressing is an important part of postoperative recovery and wound care. Its standardized operation and convenience directly affect the wound healing effect and the quality of patient recovery. In clinical nursing work, in order to improve the efficiency and safety of open wound dressing, there is a need for an easily adjustable medical dressing assistance device to provide stable and reliable operation support for open wound dressing.

[0003] However, existing dressing change assistive devices are difficult to adapt to the contours of the limb during fixation. This can easily lead to limb movement due to insecure fixation, affecting the dressing change operation. Furthermore, rigid clamping can cause local pressure and indentation on the limb, increasing the risk of epidermal damage, reducing patient comfort, and making it difficult for patients to cooperate, thus affecting the treatment effect. This is especially important for complex wounds with long operation times (such as debridement and suturing of diabetic foot), areas requiring delicate manipulation (finger), weak elderly patients, and patients with involuntary limb tremors. Summary of the Invention

[0004] The purpose of this invention is to provide an easily adjustable medical dressing change assist device. By setting an adaptive part, it solves the problem that existing dressing change assist devices are difficult to adaptively conform to the limb contour during the fixing process. This is because the limb is easily shaken due to insecure fixing, which affects the dressing change operation. Furthermore, rigid clamping can easily cause local pressure on the limb, resulting in indentations and reducing patient comfort.

[0014] The present invention has the following beneficial effects:

[0015] (1) The present invention is equipped with an adaptive part. When the inflatable airbag is pressed, the gas inside pushes the left cone block to move and squeezes the spring telescopic rod, so that the cone block separates from the ring plate. The gas enters the silicone airbag through the gap and the hose. When the inflatable airbag is released, the left cone block is reset and seals the ring plate under the action of the spring telescopic rod to prevent gas backflow. The right cone block moves under the action of suction and opens the air intake channel, and the outside gas enters the inflatable airbag. Repeated pressing and releasing can realize the continuous inflation of the silicone airbag, so that it fits the contour of the limb, realizing the progressive inflation and automatic pressure maintenance of the silicone airbag. The operation is simple and reliable. The silicone airbag can adaptively fit the contour of the limb, which can effectively fix the limb to prevent shaking and avoid local pressure to produce indentations, significantly improving the patient's comfort and fixation stability.

[0016] (2) The present invention is equipped with an exhaust section. After the dressing change is completed, pull the handle to drive the fixing rod to slide along the inner slide rail and squeeze the second spring, so that the fixing rod is released from the fixing groove of the cylindrical rod to release the lock. Then press the cylindrical rod to move downward, drive the circular plate and the trapezoidal block to move downward synchronously and squeeze the first spring, so that the trapezoidal block and the annular support plate form a gap. The gas in the silicone airbag is discharged in sequence through the hose, the inflatable airbag, the gap between the annular support plate and the trapezoidal block, the exhaust pipe and the exhaust hole, so as to realize rapid degassing, release the inflated state of the silicone airbag, and make the operation convenient. It is easy to reset the device and use it next time, while improving the overall operation continuity.

[0017] (2) The present invention is equipped with a fixing part. The patient places the limb to be dressed on the support plate and turns the handle to drive the bidirectional threaded rod to rotate. With the cooperation of the limiting slide groove, the two sliders move towards each other. The telescopic protective sleeve deforms with the movement of the slider to protect the threaded rod from the corrosion of the medicine. At the same time, the two sliders drive the fixing plate and the silicone airbag to move closer to the support plate to achieve flexible fixation on both sides of the limb. It can realize the quick centering and clamping of the limb, which is easy to operate and has stable positioning. The telescopic protective sleeve effectively blocks the corrosion of the thread by the medicine and improves the durability of the mechanism.

By setting the venting part 3, the inflation state of the silicone airbag 211 is released, which makes the operation convenient, facilitates the device reset and the next use, and improves the overall operation continuity.

[0033] The fixing part 4 includes a fixing component 41, which is installed on the top of the dressing cart 111; and a driving component 42, which is disposed on the dressing cart 111. The fixing component 41 includes a support frame 411 disposed on the top of the dressing cart 111. The support frame 411 is connected to the dressing cart 111 by a snap-fit ​​structure. The support frame 411 can also be removed and placed on the hospital bed by the snap-fit ​​structure. The top of the support frame 411 has two limiting slide grooves 412, and each of the two limiting slide grooves 412 is slidably connected to a certain component. The sliders 413 are each fixedly connected to a fixed plate 414 at their top. The sides of the two fixed plates 414 that are close to each other are fixedly connected to two silicone airbags 211. A support plate 415 is fixedly connected to the top of the support frame 411. The two sliders 413 are mirror images of each other, and the support plate 415 is located between the two sliders 413. The drive assembly 42 includes two rectangular support plates 421 fixedly connected to the inner wall of the top of the support frame 411. A bidirectional threaded rod 422 is rotatably connected between the two rectangular support plates 421. The front side of the threaded rod 422 passes through the rectangular support plate 421 located on the front side and extends outward. The bidirectional threaded rod 422 passes through two sliders 413 and is threadedly connected to the two sliders 413. A crank handle 423 is fixedly connected to the outer wall of the bidirectional threaded rod 422. A protective component is provided on the bidirectional threaded rod 422. The two sliders 413 are respectively located on the threads on both sides of the bidirectional threaded rod 422. The protective component includes several telescopic protective sleeves 424 sleeved on the outer wall of the bidirectional threaded rod 422, and two telescopic protective sleeves located on the front and rear sides. The sides of the protective sleeves 424 that are close to each other are fixedly connected to two sliders 413 respectively. The sides of the two telescopic protective sleeves 424 located on the front and rear sides that are far from each other are fixedly connected to two rectangular support plates 421 respectively. There are three telescopic protective sleeves 424. The two ends of the telescopic protective sleeve 424 located in the middle are fixedly connected to two sliders 413 respectively. By setting the fixing part 4, the limb can be quickly centered and clamped, which is easy to operate and has stable positioning. The telescopic protective sleeves 424 effectively prevent the medicine from corroding the threads and improve the durability of the mechanism.

[0034] When in use, the patient places the limb requiring dressing change on the support plate 415 and turns the crank handle 423. The crank handle 423 drives the bidirectional threaded rod 422 to rotate. Under the action of the bidirectional threaded rod 422 and the two limiting slide grooves 412, the two sliders 413 are driven to move closer to each other. The three telescopic protective sleeves 424 deform as the two sliders 413 move, preventing the threads of the bidirectional threaded rod 422 from being corroded by the medicine. When the two sliders 413 move, they drive the two fixing plates 414 to move closer to each other. The two fixing plates 414 drive the corresponding silicone airbags 211 to move closer to the support plate 415 and fix the sides of the limb.

[0035] Then, pressing the two inflatable airbags 213 causes the gas inside to push the cone-shaped block 222 on the left to move to the left, compressing the spring telescopic rod 224. This causes the spring telescopic rod 224 to deform and generate elasticity, thus moving the cone-shaped block 222 away from the annular plate 221 on the left. At this time, the gas inside the inflatable airbag 213 enters the hose 212 through the gap between the cone-shaped block 222 and the cross support plate 223, inflating the silicone airbag 211. Then, releasing the inflatable airbag 213 causes the suction force generated when the inflatable airbag 213 returns to its original position, which in turn moves the cone-shaped block 222 on the right to the left. The cone-shaped block 222 on the left side, under the elastic force of the spring telescopic rod 224, resets and blocks the annular plate 221, preventing the gas in the silicone airbag 211 from being sucked out. The cone-shaped block 222 on the right side squeezes the spring telescopic rod 224 on the right side, causing the spring telescopic rod 224 to deform and generate elastic force, which causes the cone-shaped block 222 on the right side to move away from the annular plate 221 on the right side, thereby drawing external gas into the inflatable airbag 213. By repeatedly pressing and releasing the inflatable airbag 213, the silicone airbag 211 is inflated, making the silicone airbag 211 conform to the contour of the limb, preventing limb movement and pressure marks.

[0036] Subsequently, medical staff changed the dressing on the patient's limbs;

[0037] After the dressing change is completed, pull handle 323. Handle 323 causes fixed rod 322 to slide to the left on inner slide rail 321. Handle 323 compresses spring 325, causing spring 325 to deform and generate elastic force, thereby pulling fixed rod 322 out of fixed groove 324 on cylindrical rod 317, releasing the fixation of cylindrical rod 317. Then press cylindrical rod 317 downward. Since cylindrical rod 317 is fixedly connected to circular plate 315 and trapezoidal block 313, cylindrical rod 317 drives circular plate 315 and trapezoidal block 313 downward. Circular plate 315 moves downward between two... The slide bar 314 slides downwards and compresses the two springs 318, causing them to deform and generate elastic force. The cylindrical rod 317 pushes the trapezoidal block 313 away from the annular support plate 312, creating a gap between the trapezoidal block 313 and the annular support plate 312. At this time, the gas in the silicone airbag 211 enters the inflatable airbag 213 through the hose 212. The gas enters the exhaust pipe 311 through the gap between the annular support plate 312 and the trapezoidal block 313. The gas is discharged from the exhaust pipe 311 through the six exhaust holes 316 on the circular plate 315, thereby expelling the gas in the silicone airbag 211.

[0038] Then, the bidirectional threaded rod 422 is rotated in the opposite direction, causing the two fixing plates 414 to move away from each other, thus releasing the fixation on the limb;

[0039] Since the support frame 411 and the dressing cart 111 are connected by a snap-fit ​​structure, the support frame 411 can also be removed and placed on the hospital bed through the snap-fit ​​structure, so the entire device can be placed on the hospital bed.
