Description

Technical Field

[0001] This invention relates to the field of bandage wrapping technology, and more particularly to an auxiliary device for wrapping orthopedic bandages. Background Technology

[0002] Orthopedic bandage wrapping auxiliary devices are a type of tool or equipment used to assist medical staff or users in completing orthopedic bandage wrapping operations in a standardized and efficient manner. Their core function is to solve problems such as uneven force, loss of tightness, deviation of wrapping angle, and low operation efficiency that exist in the manual wrapping process. They are suitable for orthopedic clinical scenarios such as fracture fixation, joint immobilization, and pressure bandaging for soft tissue injuries.

[0003] Currently, the traditional bandaging method used in clinical practice is still mainly done manually by medical staff. During the operation, medical staff need to hold both ends of the bandage with both hands, and then wrap it around repeatedly, layer by layer, according to the shape of the affected limb and the bandaging needs. The process is cumbersome and time-consuming, which greatly consumes the effective working time of medical staff and seriously restricts the improvement of overall treatment efficiency. Moreover, the bandage inevitably comes into direct contact with the skin of medical staff's hands. Sweat, sebum and bacteria from the environment can easily adhere to the surface of the bandage, thus contaminating it. If the bandage comes into direct contact with the patient's wound or broken skin, it will significantly increase the risk of wound infection and adversely affect the treatment effect and recovery process.

[0004] Meanwhile, there are significant individual differences in the body shape and limb size of orthopedic patients, with varying limb lengths among different patients. Existing traditional bandage-assisted dressing devices are mostly integrated fixed structures, and the height, length, and adjustment range of their dressing mechanism cannot be flexibly adjusted, making it difficult to adapt to the different body sizes and limb shapes of patients. This not only leads to insufficient bandage fit, affecting the fixation and protection effect, but may also cause compression of the patient's limb due to overly tight bandages, resulting in problems such as poor blood circulation. Therefore, there is an urgent need to develop an auxiliary device for orthopedic bandage wrapping. Summary of the Invention

[0005] Purpose of the invention: The purpose of this invention is to provide a solution to the problems of cumbersome and time-consuming traditional manual bandaging procedures, reduce the operation time and physical exertion of medical staff, improve the work efficiency of orthopedic clinical diagnosis and treatment and postoperative care, and at the same time avoid direct contact between the bandage and the hands of medical staff during the bandaging process, block the path of contamination of the bandage by hand sweat, sebum and bacteria, reduce the risk of infection of the patient's wound due to contact with contaminated bandage, and ensure the treatment effect and the patient's recovery process;

[0006] Another objective of this invention is to provide flexible adjustment of the height, width, and wrapping range of the bandage mechanism to accommodate individual differences in the body shape, length, and thickness of orthopedic patients, thereby improving the fit between the bandage and the affected limb, ensuring the bandaging fixation and protective effect, and enhancing the patient's bandaging comfort.

[0007] Technical Solution: An auxiliary device for orthopedic bandage wrapping includes a base plate. A groove is formed on the upper surface of the base plate. A bidirectional screw is rotatably mounted inside the groove via a rotating shaft. A threaded block one is threaded onto the outer wall of the bidirectional screw. A threaded block two is threaded onto the outer wall of the bidirectional screw to the left of the threaded block one. A placement mechanism is provided on the upper surface of the threaded block one. An mounting plate is fixedly mounted on the upper surface of the threaded block two. A turntable is rotatably mounted inside the mounting plate via a rotating shaft. A gear ring is fixedly mounted inside the mounting plate to the right of the turntable. A winding mechanism is provided on the right side of the turntable, and a control mechanism is provided on the left side of the turntable. The winding mechanism includes gears. The gear is rotatably mounted on the left side and the right side of the turntable via a rotating shaft. The outer wall of the gear meshes with the inner wall of the gear ring. A take-up column is fixedly mounted on the right side of the gear. A fixed wheel is fixedly mounted on the outer wall of the take-up column. A clamping wheel is slidably mounted on the outer wall of the take-up column and located to the right of the fixed wheel. A guide rod is fixedly mounted on the right side of the fixed wheel. The right end of the guide rod extends through to the right side of the clamping wheel and is fixedly mounted with a fixing block. A spring is fixedly mounted between the left side of the fixed wheel and the right side of the clamping wheel and located on the outer wall of the guide rod. A tool holder is fixedly mounted on the right side of the fixed wheel. The right side of the tool holder contacts the left side of the clamping wheel. A blade is slidably mounted inside the tool holder.

[0008] Furthermore, the control mechanism includes a pressing column, the right side of which is fixedly connected to the left side of the turntable, a rotating handle is slidably mounted on the outer side of the pressing column, and a spring is fixedly mounted between the inner right side of the rotating handle and the left side of the pressing column.

[0009] Furthermore, a pressing rod is fixedly installed on the inner side of the rotating handle, and the right end of the pressing rod extends through the interior of the tool holder and is fixedly connected to the left side of the blade.

[0010] Furthermore, the placement mechanism includes a base, the lower surface of which is fixedly connected to the upper surface of the second threaded block, a threaded rod is rotatably mounted on the upper surface of the base via a pivot, an anti-slip sleeve is fixedly mounted on the outer side wall of the threaded rod, and a third threaded block is threadedly mounted on the outer side wall of the threaded rod above the anti-slip sleeve.

[0011] Furthermore, guide rods two are fixedly installed on the upper surface of the base and on both sides of the anti-slip sleeve, with the top end of the guide rods two penetrating into the interior of the threaded block three.

[0012] Furthermore, a placement block is fixedly installed on the upper surface of the threaded block three.

[0013] Furthermore, the left end of the bidirectional screw extends through to the left side of the base plate and is fixedly mounted with a rotary handle.

[0014] Beneficial effects: The device is equipped with a bidirectional screw and a threaded block one and a threaded block two working together. By rotating the second hand, the placement mechanism and the mounting plate can be driven to move synchronously in opposite directions or in opposite directions along the slide. The distance between the two can be quickly adjusted to fit the affected limbs of different lengths. At the same time, the winding mechanism is driven by the meshing of gears and gear rings. During the rotation of the turntable, the winding column can be driven to rotate, realizing the automatic winding of the bandage. This replaces the traditional pure manual reciprocating winding operation, greatly shortens the bandaging time, and is suitable for high-intensity work scenarios such as batch patient treatment and emergency treatment. It significantly improves the work efficiency of orthopedic clinical diagnosis and treatment and postoperative care.

[0015] The fixed wheel and clamping wheel on the winding column form a clamping structure through the elastic force of spring one, which can directly fix the bandage roll on the winding column. During the bandaging process, medical staff do not need to directly touch the bandage body with their hands. At the same time, the control mechanism can realize the automatic extension and retraction of the blade through the linkage of the pressing column, the turning hand one and the squeezing rod to quickly cut the bandage. The entire process avoids contact between the hands and the bandage, blocks the contamination path of sweat, sebum and bacteria, effectively reduces the probability of infection of the patient's wound due to contact with contaminated bandage, and ensures the treatment effect and recovery process.

[0016] The placement mechanism moves the threaded block three up and down along the guide rod two by rotating the threaded rod, which can flexibly adjust the height of the placement block to improve patient comfort. Combined with the bidirectional screw-driven spacing adjustment structure, it can meet the differences in limb size among different patients, ensure the fit of the bandage to the affected limb during the wrapping process, and improve the fixation and protection effect. At the same time, the automatic wrapping method can evenly control the wrapping force of the bandage, avoiding the problem of overly tight bandaging caused by uneven force during manual bandaging, preventing poor blood circulation caused by limb compression, and improving the patient's comfort after bandaging.

[0024] To make the technical solution of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0025] Example

[0026] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, an auxiliary device for wrapping orthopedic bandages is provided, including a base plate 1. A groove 2 is formed on the upper surface of the base plate 1. A bidirectional screw 3 is rotatably mounted inside the groove 2 via a rotating shaft. A threaded block 4 is threaded onto the outer wall of the bidirectional screw 3. A threaded block 5 is threaded onto the outer wall of the bidirectional screw 3 to the left of the threaded block 4. A placement mechanism 6 is provided on the upper surface of the threaded block 4. An mounting plate 7 is fixedly mounted on the upper surface of the threaded block 5. A turntable 8 is rotatably mounted inside the mounting plate 7 via a rotating shaft. A gear ring 9 is fixedly mounted inside the mounting plate 7 to the right of the turntable 8. A winding mechanism 10 is provided on the right side of the turntable 8. A control mechanism 11 is provided on the left side of the turntable 8. The winding mechanism 10 includes a gear 1001. The left side of the gear 1001 and the right side of the turntable 8 are rotatably mounted via a rotating shaft. The sidewall meshes with the inner sidewall of the gear ring 9. A take-up column 1002 is fixedly installed on the right side of the gear 1001. A fixed wheel 1003 is fixedly installed on the outer sidewall of the take-up column 1002. A clamping wheel 1004 is slidably installed on the outer sidewall of the take-up column 1002 and on the right side of the fixed wheel 1003. A guide rod 1005 is fixedly installed on the right side of the fixed wheel 1003. The right end of the guide rod 1005 extends through to the right side of the clamping wheel 1004 and a fixed block 1006 is fixedly installed. A spring 1007 is fixedly installed between the left side of the fixed wheel 1003 and the right side of the clamping wheel 1004 and on the outer sidewall of the guide rod 1005. A tool holder 1008 is fixedly installed on the right side of the fixed wheel 1003. The right side of the tool holder 1008 contacts the left side of the clamping wheel 1004. A blade 1009 is slidably installed inside the tool holder 1008.

[0027] The control mechanism 11 includes a pressing column 1101. The right side of the pressing column 1101 is fixedly connected to the left side of the turntable 8. A first handle 1102 is slidably installed on the outside of the pressing column 1101. A second spring 1103 is fixedly installed between the right side of the first handle 1102 and the left side of the pressing column 1101.

[0028] A pressing rod 1104 is fixedly installed on the inner side of the rotating handle 1102. The right end of the pressing rod 1104 extends through the interior of the tool holder 1008 and is fixedly connected to the left side of the blade 1009.

[0029] The left end of the double-ended screw 3 extends through to the left side of the base plate 1 and is fixedly installed with a rotary handle 12;

[0030] Through the threaded engagement structure of the bidirectional screw 3 with the threaded block 4 and the threaded block 5, rotating the handle 12 can drive the bidirectional screw 3 to move the placement mechanism 6 and the mounting plate 7 synchronously towards or away from each other along the slide groove 2, so as to achieve precise and convenient adjustment of the distance between the two. It can quickly adapt to orthopedic limbs of different lengths. The adjustment process does not require additional disassembly of parts, the operation steps are simple, and the preparation efficiency before bandaging is further improved.

[0031] In the winding mechanism 10, the gear 1001 meshes with the gear ring 9. While the rotating turntable 8 drives the winding column 1002 to rotate, it can also drive the winding column 1002 to rotate on its own. With the elastic clamping effect of the fixed wheel 1003 and the clamping wheel 1004 on the bandage roll, the bandage can be automatically and evenly wound, avoiding problems such as uneven layer overlap and inconsistent tightness that occur in manual bandaging, and ensuring the bandaging fixation effect. At the same time, the cooperation structure of the guide rod 1005 and the spring 1007 allows for quick replacement of the bandage roll, improving the practicality of the device.

[0032] The control mechanism 11 uses a linkage design between the rotary handle 1102, the squeezing rod 1104 and the blade 1009. Pressing the rotary handle 1102 will push the blade 1009 to slide along the blade holder 1008, achieving rapid cutting of the bandage. The cutting process does not require medical personnel to touch the bandage, further avoiding the risk of contamination. In addition, the spring 1103 can drive the rotary handle 1102 and the blade 1009 to automatically reset, which is convenient for subsequent repeated operations and improves the continuous use performance of the device.

[0033] like Figure 1 , Figure 2 , Figure 3 and Figure 6 As shown, the placement mechanism 6 includes a base 601, the lower surface of the base 601 is fixedly connected to the upper surface of the threaded block 5, the upper surface of the base 601 is rotatably mounted with a threaded rod 602 via a rotating shaft, the outer side wall of the threaded rod 602 is fixedly mounted with an anti-slip sleeve 603, and the outer side wall of the threaded rod 602 and above the anti-slip sleeve 603 is threadedly mounted with a threaded block 604.

[0034] Guide rods 605 are fixedly installed on the upper surface of the base 601 and on both sides of the anti-slip sleeve 603. The top of the guide rods 605 penetrates into the interior of the threaded block 604.

[0035] A placement block 606 is fixedly installed on the upper surface of the threaded block 604;

[0036] In the placement mechanism 6, the base 601 is fixedly connected to the threaded block 5. With the spacing adjustment structure of the bidirectional screw 3, it can move synchronously with the threaded block 5 to ensure that the relative position of the placement block 606 and the winding mechanism 10 always matches the wrapping requirements, thereby improving the overall coordination and stability of the device.

[0037] The threaded engagement design between the threaded rod 602 and the threaded block 604 allows the threaded block 604 to be driven to move the placement block 606 up and down by rotating the threaded rod 602. This enables flexible adjustment of the height of the placement block 606, improving patient comfort and further enhancing the practicality of the device.

[0038] The anti-slip sleeve 603 fixed to the outer wall of the threaded rod 602 can increase the friction between the operator's hand and the threaded rod 602, avoid slippage during rotation, and improve the convenience and accuracy of height adjustment operation; the guide rod 605 located on both sides of the anti-slip sleeve 603 on the base 601, with its top end penetrating into the threaded block 604, can guide and limit the up and down movement of the threaded block 604, prevent the threaded block 604 from shifting with the rotation of the threaded rod 602, ensure the stability and accuracy of the height adjustment of the placement block 606, and thus ensure the stability of the affected limb after placement and improve the bandaging effect;

[0039] The placement block 606 provides a stable support platform for the affected limb. Combined with the automatic winding function of the winding mechanism 10, it can keep the affected limb in a fixed position during the bandaging process, avoiding problems such as bandaging deviation and uneven tightness caused by the movement of the affected limb, and further ensuring the quality of bandaging.

[0040] The embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention. Therefore, the scope of protection of this patent should be determined by the appended claims.
