Description

Technical Field

[0001] This invention belongs to the field of hospital surgical technology, and in particular relates to a hospital surgical nursing dressing change device and its usage method. Background Technology

[0002] The hospital's surgical department is a crucial department for diagnosing and treating surgical diseases, encompassing subspecialties such as general surgery, orthopedics, thoracic surgery, and neurosurgery. It treats conditions like trauma, tumors, and deformities through surgery and other methods. Equipped with advanced equipment and a professional team, it emphasizes preoperative assessment, precise intraoperative procedures, and rapid postoperative recovery, providing personalized treatment plans to safeguard public health. The hospital's surgical wound care and dressing change equipment is of paramount importance. It ensures standardized and aseptic dressing changes, reducing the risk of infection. Tools such as sterile forceps and cotton balls maintain wound cleanliness, while appropriate dressings protect the wound, absorb exudate, and promote healing. Portable devices facilitate bedside operation, improve nursing efficiency, and reduce patient discomfort. Standardized devices also reduce operational errors by medical staff, serving as a fundamental guarantee for the quality of surgical wound care and directly impacting patient recovery outcomes.

[0003] Common hospital surgical dressing changes simply involve placing the adult patient's limb on a regular support board and using elastic bands to restrain the limb, or allowing the adult patient to control the limb themselves. Because the support board and elastic bands are not adjustable, they cannot be used for adult patients with limbs of different lengths and thicknesses. Furthermore, medical supplies are usually stored in storage boxes and old dressings are placed in waste collection boxes, requiring medical staff to frequently open the storage boxes and waste collection boxes, which is time-consuming, labor-intensive, and affects dressing change efficiency. Summary of the Invention

[0004] To address the problems existing in the prior art, this invention provides a surgical nursing dressing change device and its usage method for hospitals. It features adjustable support plates and elastic bands based on the limb length of adult patients. During dressing changes, the medical tool storage box automatically opens, eliminating the need for medical staff to frequently open and close the storage box and waste collection box. This overcomes or at least partially solves the problems of the non-adjustable support plate and elastic bands, which prevent applicability to limbs of different lengths and thicknesses in adult patients. Furthermore, the present invention addresses the issues of medical tools typically being stored inside the storage box and old dressings needing to be placed inside the waste collection box, requiring medical staff to frequently open and close these boxes, resulting in time-consuming and labor-intensive processes that negatively impact dressing change efficiency.

[0012] In a preferred embodiment of the present invention, a storage component is provided on the rear surface of the fixing plate, the storage component comprising: Second irregular-shaped plate: The front end face of the second irregular-shaped plate is fixedly connected to the rear surface of the fixed plate; Storage box: The front surface of the storage box is fixedly connected to the rear surface of the support base; Storage slot: The lower surface of the storage slot is slidably connected to the inner wall of the storage box; Third spring: The front end face of the third spring is fixedly connected to the inner wall of the storage box, and the rear end face of the third spring is fixedly connected to the front surface of the storage slot; Card slot: The card slot is formed on the lower surface of the storage slot; Second through slot: The second through slot is formed on the lower surface of the storage box; Card: The outer surface of the card is in contact with the inner wall of the card slot and the second through slot, and the lower surface of the card is fixedly connected to the upper surface of the second irregular plate.

[0013] In a preferred embodiment of the present invention, the first step is as follows: based on the patient's limb length and wound location, a rotating drive rod is used to rotate a threaded rod. The threaded rod drives a transmission block to slide along the inner wall of the first groove. The transmission block can drive the support ring to move laterally via the connecting rod on the upper surface until the distance between the two support rings is close to the length of the patient's limb. Only then can the patient's limb be placed on the upper surface of the support ring. When the patient's limb is on the upper surface of the support ring, the weight of the limb can press the support ring downward. The support ring drives the connecting rod to move downward and squeeze the first spring, causing the first spring to generate elastic force. The connecting rod on the right pushes the support plate downward along the inner wall of the first groove, causing the support plate to move downward and pull the auxiliary rod. The auxiliary rod then squeezes the second spring, causing the second spring to generate elastic force. At the same time, the support plate can drive the locking piece to move downward together via the connecting plate until the locking piece corresponds to the locking groove. At this time, the second tension spring releases its tension, pulling the locking piece into the locking groove and tightly fitting it to the locking groove, thus fixing the support plate. Step 2: The connecting rod moves down and can drive the stroke column through the fixed plate, so that the stroke column moves down along the inner wall of the second stroke groove. The stroke column can squeeze the inner wall of the first stroke groove and move along the inner wall of the first stroke groove. At this time, the partition is forced to rotate downward, so that the top of the fixed box opens, making it easy for the staff to throw the old gauze directly into the collection tank from the hollow in the middle of the support base. Step 3: As the fixing plate moves down, the second irregular plate can also move the clip down together, so that the clip does not stick to the inner wall of the slot and the second through slot. At this time, the third spring can release the elastic force and push the storage slot to slide outward along the inner wall of the storage box, making it easier for staff to take out tools more quickly. Step 4: Pass the elastic band through the first through groove and make the elastic band fit tightly against the patient's limb. Pull the puller downwards, and the puller moves down to pull the first tension spring, causing the first tension spring to generate tension. At the same time, the puller moves the clamping block downwards until the gap between the clamping block and the clamping groove is large enough for the elastic band to pass through. The elastic band is then passed through and moved to the appropriate position. Stop pulling the puller, and the first tension spring releases its tension. Pull the clamping block back, and the outer surface of the clamping block fits tightly against the limiting hole and the clamping groove, fixing the elastic band. Step 5: When the staff finishes changing the dressing, remove the collection tank and clean the old gauze and medication inside. Finally, similarly, first loosen the elastic band so the patient can remove the limb from the support ring. Then, the staff pulls the locking piece outward to disengage it from the locking slot. At this time, both the first and second springs release their elasticity. Then, press the storage tank back, which compresses the third spring, causing it to generate elasticity and push the support ring back. Finally, all tools and devices return to their initial state.

[0014] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. This invention, by setting up a support component, a transmission component, and an auxiliary component, uses a rotating drive rod to drive a threaded rod to rotate. The threaded rod drives a transmission block to slide along the inner wall of the first sliding groove through its threads. The transmission block can drive the support ring to move laterally through the connecting rod on its upper surface until the distance between the two support rings is close to the length of the patient's limb. Only then can the patient's limb be placed on the upper surface of the support ring, thus achieving the effect of adjusting the distance between the support rings according to the length of the patient's limb and the location of the wound.

[0015] 2. This invention, by setting a fixing component and a clamping component, allows the elastic band to pass through the first through groove and fit tightly against the patient's limb. By pulling down the pulling member, the pulling member moves downward and pulls the first tension spring, causing the first tension spring to generate tension. At the same time, the pulling member drives the clamping block to move downward until the gap between the clamping block and the clamping groove is large enough for the elastic band to pass through. The elastic band is then moved to a suitable position. When the pulling member is stopped, the first tension spring releases its tension, pulling the clamping block back. The outer surface of the clamping block fits tightly against the limiting hole and the clamping groove, fixing the elastic band and achieving the effect of limiting the patient's limb with the elastic band.

[0016] 3. By setting up a locking component, the support plate can move down together with the locking component through the connecting plate until the locking component corresponds to the locking groove. At this time, the second tension spring releases the tension, pulling the locking component into the locking groove and tightly fitting it into the locking groove, thus achieving the effect of fixing the support plate.

[0017] 4. By setting up a collection component, the connecting rod moves down and the fixed plate drives the travel column, so that the travel column moves downward along the inner wall of the second travel groove. The travel column can squeeze the inner wall of the first travel groove and move along the inner wall of the first travel groove. At this time, the partition is forced to rotate downward, so that the top of the fixed box opens, which makes it convenient for workers to throw old gauze directly into the collection groove from the hollow part in the middle of the support base.

[0018] 5. By setting up a storage component, when the fixing plate moves down, the second irregular plate can drive the card to move down together, so that the card does not stick to the inner wall of the card slot and the second through slot. At this time, the third spring can release its elastic force and push the storage slot to slide outward along the inner wall of the storage box, which achieves the effect of making it easier for workers to retrieve tools more quickly.

[0025] Using the above scheme: Based on the patient's limb length and wound location, the drive rod 45 is rotated, which drives the threaded rod 44 to rotate. The threaded rod 44 drives the transmission block 43 to slide along the inner wall of the first slide groove 42 through the thread. The transmission block 43 can drive the support ring 31 to move laterally through the connecting rod 32 on the upper surface until the distance between the two support rings 31 is close to the length of the patient's limb. Only then can the patient's limb be placed on the upper surface of the support ring 31. When the patient's limb is on the upper surface of the support ring 31, due to the weight of the limb, the support ring 31 can be pressed downward. The support ring 31 drives the connecting rod 32 to move downward and squeeze the first spring 34, so that the first spring 34 generates elastic force. The right connecting rod 32 pushes the support plate 41 downward along the inner wall of the first slide groove 42, so that the support plate 41 moves downward.

At this time, the third spring 104 can release the elastic force and push the storage slot 103 to slide outward along the inner wall of the storage box 102, making it easier for the staff to take out the tools more quickly.

[0038] refer to Figures 1 to 6 The method includes the following steps: Step 1: Based on the patient's limb length and wound location, the drive rod 45 is rotated, causing the threaded rod 44 to rotate. The threaded rod 44, through its threads, drives the transmission block 43 to slide along the inner wall of the first groove 42. The transmission block 43, through the connecting rod 32 on its upper surface, drives the support ring 31 to move laterally until the distance between the two support rings 31 is close to the length of the patient's limb. Only then can the patient's limb be placed on the upper surface of the support ring 31. When the patient's limb is on the upper surface of the support ring 31, the weight of the limb will press the support ring 31 downwards. The support ring 31 drives the connecting rod 32 to move down and squeezes the first spring 34, causing the first spring 34 to generate elastic force. The right connecting rod 32 pushes the support plate 41 down along the inner wall of the first slide groove 42, causing the support plate 41 to move down and pull the auxiliary rod 51. The auxiliary rod 51 then squeezes the second spring 52, causing the second spring 52 to generate elastic force. At the same time, the support plate 41 can drive the locking member 82 to move down together through the connecting plate 83 until the locking member 82 corresponds to the locking groove 81. At this time, the second tension spring 84 releases its tension, pulling the locking member 82 into the locking groove 81 and tightly fitting it to the locking groove 81, thus fixing the support plate 41. Step 2: The downward movement of the connecting rod 32 can drive the stroke column 95 through the fixing plate 97, so that the stroke column 95 moves downward along the inner wall of the second stroke groove 96. The stroke column 95 can squeeze the inner wall of the first stroke groove 94 and move along the inner wall of the first stroke groove 94. At this time, the partition 93 is forced to rotate downward, so that the top of the fixing box 91 opens, making it convenient for the staff to throw the old gauze directly into the collection tank 92 from the hollow part in the middle of the support base 2. Step 3: As the fixing plate 97 moves down, the second irregular plate 101 can drive the clip 107 to move down together, so that the clip 107 does not stick to the inner wall of the slot 105 and the second through slot 106. At this time, the third spring 104 can release the elastic force and push the storage slot 103 to slide outward along the inner wall of the storage box 102, making it easier for the staff to take out the tools more quickly. Step 4: Pass the elastic band 61 through the first through groove 62 and make the elastic band 61 fit tightly against the patient's limb. Pull the pull member 74 downward. The pull member 74 moves down and pulls the first tension spring 75, so that the first tension spring 75 generates tension. At the same time, the pull member 74 drives the clamping block 73 to move down until the gap between the clamping block 73 and the clamping groove 72 is large enough for the elastic band 61 to pass through. The elastic band 61 is then moved to the appropriate position. Stop pulling the pull member 74. The first tension spring 75 releases tension. Pull the clamping block 73 back. The outer surface of the clamping block 73 fits tightly against the limiting hole 63 and the clamping groove 72, fixing the elastic band 61. Step 5: When the staff finishes changing the dressing, remove the collection tank 92 and clean the old gauze and old medicine inside the collection tank 92. Finally, similarly, first loosen the elastic band 61 so that the patient can remove the limb from the support ring 31. The staff then pulls the locking piece 82 outward so that the locking piece 82 leaves the locking slot 81. At this time, the first spring 34 and the second spring 52 release their elasticity. Then press the storage tank 103 back, and the storage tank 103 squeezes the third spring 104, so that the third spring 104 generates elasticity and pushes the support ring 31 to move back. Finally, all tools and devices return to their initial state.

[0039] Working principle of the invention: In use, based on the patient's limb length and wound location, the drive rod 45 is rotated, causing the threaded rod 44 to rotate. The threaded rod 44, through its threads, drives the transmission block 43 to slide along the inner wall of the first groove 42. The transmission block 43, via the connecting rod 32 on its upper surface, drives the support ring 31 to move laterally until the distance between the two support rings 31 is close to the length of the patient's limb. Only then can the patient's limb be placed on the upper surface of the support ring 31. When the patient's limb is on the upper surface of the support ring 31, the weight of the limb will press the support ring 31 downwards. The connecting rod 32 moves down and compresses the first spring 34, causing the first spring 34 to generate elastic force. The right connecting rod 32 pushes the support plate 41 down along the inner wall of the first slide groove 42, causing the support plate 41 to move down and pull the auxiliary rod 51. The auxiliary rod 51 then compresses the second spring 52, causing the second spring 52 to generate elastic force. At the same time, the support plate 41 can drive the locking member 82 to move down together through the connecting plate 83 until the locking member 82 corresponds to the locking groove 81. At this time, the second tension spring 84 releases its tension, pulling the locking member 82 into the locking groove 81 and tightly fitting it to the locking groove 81, thus fixing the support plate 41. The downward movement of the connecting rod 32 can drive the stroke column 95 through the fixing plate 97, so that the stroke column 95 moves downward along the inner wall of the second stroke groove 96. The stroke column 95 can squeeze the inner wall of the first stroke groove 94 and move along the inner wall of the first stroke groove 94. At this time, the partition 93 is forced to rotate downward, so that the top of the fixing box 91 opens, making it convenient for the staff to throw the old gauze directly into the collection tank 92 from the hollow part in the middle of the support base 2. As the fixing plate 97 moves down, the second irregular plate 101 can drive the clip 107 to move down together, so that the clip 107 does not stick to the inner wall of the slot 105 and the second through slot 106. At this time, the third spring 104 can release the elastic force and push the storage slot 103 to slide outward along the inner wall of the storage box 102, making it easier for the staff to take out the tools more quickly. Then, the elastic band 61 is passed through the first through groove 62 and made to fit tightly against the patient's limb. By pulling down the puller 74, the puller 74 moves down and pulls the first tension spring 75, so that the first tension spring 75 generates tension. At the same time, the puller 74 drives the clamping block 73 to move down until the gap between the clamping block 73 and the clamping groove 72 is large enough for the elastic band 61 to pass through. The elastic band 61 is then moved to the appropriate position. The puller 74 is stopped, the first tension spring 75 releases tension, and the clamping block 73 is pulled back. The outer surface of the clamping block 73 fits tightly against the limiting hole 63 and the clamping groove 72, fixing the elastic band 61. When the staff finishes changing the dressing, they pull out the collection tank 92 and clean the old gauze and medication inside. Finally, similarly, they loosen the elastic band 61, allowing the patient to remove their limb from the support ring 31. The staff then pulls the locking piece 82 outward, causing it to leave the locking slot 81. At this point, the first spring 34 and the second spring 52 release their elasticity. The storage tank 103 is then pressed back, squeezing the third spring 104, which generates elasticity and pushes the support ring 31 back. Ultimately, all tools and devices return to their initial state, improving the creativity of a hospital surgical dressing change device and its usage method, making it easier for users to use.

[0040] In summary, this surgical nursing dressing change device and its usage method, by setting up a support component 3, a transmission component 4, an auxiliary component 5, a fixing component 6, a clamping component 7, a positioning component 8, a collection component 9, and a storage component 10, solves the problems that the support plate and elastic band cannot be adjusted, making it unsuitable for the limbs of adult patients of different lengths and thicknesses. Furthermore, the device addresses the issues of medical supplies typically being placed inside a storage box and old dressings needing to be placed inside a waste collection box, requiring medical staff to frequently open the storage box and waste collection box, which is time-consuming, labor-intensive, and affects dressing change efficiency.

9. A hospital surgical nursing dressing change device and its method of use as described in claims 1 to 8, the method of use includes the following steps: Step 1: According to the patient's limb length and wound location, by rotating the drive rod (45), the drive rod (45) drives the threaded rod (44) to rotate, and the threaded rod (44) drives the transmission block (43) to slide along the inner wall of the first slide groove (42) through the thread. The transmission block (43) can drive the support ring (31) to move laterally through the connecting rod (32) on the upper surface until the distance between the two support rings (31) is close to the length of the patient's limb, then the patient's limb can be placed on the upper surface of the support ring (31). When the patient's limb is on the upper surface of the support ring (31), due to the weight of the limb, the support ring (31) can be moved laterally. 31) Press down, the support ring (31) drives the connecting rod (32) to move down and squeeze the first spring (34), so that the first spring (34) generates elastic force. The right connecting rod (32) pushes the support plate (41) down along the inner wall of the first slide groove (42), so that the support plate (41) moves down and pulls the auxiliary rod (51). The auxiliary rod (51) squeezes the second spring (52), so that the second spring (52) generates elastic force. At the same time, the support plate (41) can drive the locking piece (82) to move down together through the connecting plate (83) until the locking piece (82) corresponds to the locking groove (81). At this time, the second tension spring (84) releases the tension, pulls the locking piece (82) into the locking groove (81) and fits tightly with the locking groove (81), fixing the support plate (41). Step 2: The connecting rod (32) moves down and can drive the stroke column (95) through the fixed plate (97), so that the stroke column (95) moves down along the inner wall of the second stroke groove (96). The stroke column (95) can squeeze the inner wall of the first stroke groove (94) and move along the inner wall of the first stroke groove (94). At this time, the partition (93) is forced to rotate downward, so that the top of the fixed box (91) opens, making it easy for the staff to throw the old gauze directly into the collection tank (92) from the hollow part in the middle of the support base (2). Step 3: As the fixing plate (97) moves down, the second irregular plate (101) can drive the clip (107) to move down together, so that the clip (107) does not stick to the inner wall of the slot (105) and the second through slot (106). At this time, the third spring (104) can release the elastic force and push the storage slot (103) to slide outward along the inner wall of the storage box (102), so that the staff can take out the tools more quickly. Step 4: Pass the elastic band (61) through the first through groove (62) and make the elastic band (61) fit tightly against the patient's limb. By pulling down the puller (74), the puller (74) moves down and pulls the first tension spring (75), so that the first tension spring (75) generates tension. At the same time, the puller (74) drives the clamping block (73) to move down until the gap between the clamping block (73) and the clamping groove (72) is large enough for the elastic band (61) to pass through. Move the elastic band (61) to the appropriate position, stop pulling the puller (74), the first tension spring (75) releases the tension, pull the clamping block (73) back, the outer surface of the clamping block (73) fits tightly with the limiting hole (63) and the clamping groove (72) to fix the elastic band (61); Step 5: When the staff finishes changing the dressing, pull out the collection tank (92) and clean the old gauze and old medicine inside the collection tank (92). Finally, similarly, first loosen the elastic band (61) so that the patient can remove the limb from the support ring (31). The staff then pulls the locking piece (82) outward so that the locking piece (82) leaves the locking slot (81). At this time, the first spring (34) and the second spring (52) release their elasticity. Then press the storage tank (103) back. The storage tank (103) squeezes the third spring (104), so that the third spring (104) generates elasticity and pushes the support ring (31) to move back. Finally, all tools and devices return to their initial state.
