Description

Technical Field

[0001] This utility model relates to the field of bandaging support technology, specifically to an easily adjustable emergency bandaging support device. Background Technology

[0002] For patients with injuries to the arms or legs, hospitals need to use bandage support devices to fix the injured area, apply pressure to stop bleeding, and fix the dressing. Currently, the bandage support devices used in clinical practice have poor mobility and adjustability, and cannot flexibly adjust the support height and angle according to the patient's specific situation. As a result, during the bandaging process, it is difficult for the patient's limb to be in a comfortable and appropriate position, which not only increases the patient's pain, but also affects the quality of bandaging.

[0003] To address the issues of poor mobility and adjustability in existing bandaging support devices, Chinese Patent Publication No. CN212973373U discloses an emergency department nursing bandaging support device. This device includes a base with four support pillars at its lower corners. Each support pillar has a frosted pad at its lower end. A threaded post is mounted on the front of the upper end of the base, with a rotating nut threaded onto the post. A placement plate is fitted onto the threaded post, with its lower end resting on the upper end of the rotating nut. A blocking cap is mounted on the upper end of the threaded post. A rubber protective pad is mounted in the middle of the upper end of the placement plate. An arc-shaped reinforcing plate is connected to the rear of the upper end of the base. This emergency department nursing bandaging support device allows for easy adjustment of the placement plate's height through the threaded post and rotating nut, adapting to different bandaging needs. A butterfly hinge allows the rotating placement plate to be folded away, and a pressing seat facilitates fixing the limb to be bandaged, making bandaging easier for medical staff.

[0004] In the above scheme, by setting up a downward vertical elbow clamp driving pressing seat and a placement plate and rubber protective pad on it, the compression cooperation under the action of external force can achieve the effect of fixing the affected area. In actual use, the injured parts of patients are often the arms and legs. To cope with patients of different body types and different injured parts, the device needs to be able to be quickly adjusted and fixed. Therefore, we have proposed an easily adjustable emergency bandaging support device. Utility Model Content

[0005] To address the aforementioned technical problems, embodiments of this application provide an easily adjustable emergency bandaging support device, comprising:

[0006] The rotating base has two symmetrically arranged rotating bases, and a locking mechanism is provided between the two rotating bases. The two rotating bases are connected and rotatably connected through one end. The two rotating bases are restricted from relative rotation by the locking mechanism, so that the two rotating bases can form a certain angle and be fixed.

[0007] The two rotating bases are each equipped with a support mechanism. The support mechanism is used to fix both ends of the injured part of the patient. The support mechanism slides relative to the rotating base to adjust the distance between the support mechanisms and fix the injured part of the patient's arm or leg.

[0008] The support mechanism is equipped with a sliding locking mechanism to fix the support mechanism on the rotating base and prevent the support mechanism from sliding and causing secondary injury to the patient.

[0009] In some embodiments, the locking mechanism includes a pull pin and a friction plate. The pull pin is slidably connected to one side of the rotating base, and a friction plate is installed at the bottom of the pull pin. The friction plate contacts the surface of the other side of the rotating base, and a spring is provided between the pull pin and the rotating base to compress the friction plate, thereby fixing the two rotating bases.

[0010] In some embodiments, the sliding locking mechanism includes a locking handle mounted on a mounting housing. The locking handle is rotatably connected to the mounting housing via a rotating pin. A slide rod is fixed on the inner wall of the mounting housing. A slide groove is formed on the surface of the slide rod. A sliding locking block is provided on the slide rod. The slide rod slides through the slide groove and engages with the sliding locking block. A spring is provided between the sliding locking block and the mounting housing. The locking handle contacts the sliding locking block. Rotating the locking handle drives the sliding locking block to slide and lock along the slide rod. A rack is provided on the rotating base. The bottom extension end of the sliding locking block can engage with the rack on the rotating base to restrict the sliding of the support mechanism on the rotating base.

[0011] In some embodiments, the support mechanism includes a support block with elastic rollers mounted on both sides of the support block and tension straps provided on the elastic rollers for securing the patient's arm or leg to the support block.

[0012] In some embodiments, a slider is provided on the support block, the support block and the slider are slidably connected, a spring rod is provided between the slider and the support block, the slider and the spring rod form a sliding limiting mechanism, and sliders and spring rods are provided at both ends of the elastic roller to drive the elastic roller to slide relative to the support block, thereby reducing the gap between the patient's arm or leg and the support block.

[0013] In some embodiments, the elastic roller includes a rotating cylinder with connecting blocks on both sides. The rotating cylinder and the connecting blocks rotate in cooperation. A torsion spring is fixed between the two connecting blocks, and a torsion block is fixed on the torsion spring. The torsion block is fixedly connected to the rotating cylinder.

[0014] In some embodiments, the tightening band is made of polyurethane fabric, and the tightening band joint is provided with Velcro to connect the two ends of the tightening band to fix the patient's arm or leg.

[0015] This utility model has at least the following beneficial effects:

[0016] 1. This utility model features a sliding locking mechanism controlled by a locking handle. When the locking handle is open, the sliding locking block moves, causing the bottom extension of the sliding locking block to engage with the rack on the rotating base. When the locking handle is closed, the bottom extension of the sliding locking block disengages from the rack, thus enabling the sliding adjustment and rapid fixation of the support mechanism relative to the rotating base. By using the friction plate at the bottom of the pull pin on the locking mechanism to pull and release the pull pin, the angle between the two rotating bases can be quickly adjusted and fixed. A tightening strap is provided on the retractable elastic roller, thereby enabling rapid adjustment and fixation of the injured parts of the arms or legs of patients of different body types.

[0017] 2. This utility model uses a torsion spring to drive the elastic roller, combined with the sliding limit design of the slider and spring rod, which can actively conform to the shape of the limb. The tightening strap is fixed with Velcro for further reinforcement. The dual fixing mechanism (elastic fit + tightening strap) effectively reduces the gap between the limb and the support block, avoids secondary damage, and improves the fixation stability.

[0018] 3. This utility model adopts a spring reset design for both the locking mechanism and the sliding locking mechanism. It can achieve quick unlocking or locking with one hand by pulling the pin and locking handle. The polyurethane tightening band is soft and easy to adjust, which simplifies the operation process, reduces the difficulty of operation for emergency personnel, and is suitable for quick fixation in emergency situations, thus improving the efficiency of treatment.

Detailed Implementation

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Example 1:

[0030] Please see Figure 1 3-4, 7-8, This utility model provides a technical solution: an easily adjustable emergency bandaging support device, comprising:

[0031] Two rotating bases 2 are symmetrically arranged. A locking mechanism 3 is provided between the two rotating bases 2. The two rotating bases 2 are connected by one end and rotated. The two rotating bases 2 are restricted from relative rotation by the locking mechanism 3, so that the two rotating bases 2 can form a certain angle and be fixed.

[0032] Support mechanism 1 is provided on both rotating bases 2. The support mechanism 1 is used to fix the two ends of the injured part of the patient. The support mechanism 1 slides relative to the rotating base 2 to adjust the distance between the support mechanisms 1 and fix the injured part of the patient's arm or leg.

[0033] The support mechanism 1 is provided with a sliding locking mechanism 11, which is used to fix the support mechanism 1 on the rotating base 2 to prevent the support mechanism 1 from sliding and causing secondary injury to the patient.

[0034] The locking mechanism 3 includes a pull pin 31 and a friction plate 32. The pull pin 31 is slidably connected to one side of the rotating base 2. The friction plate 32 is installed at the bottom of the pull pin 31. The friction plate 32 is in contact with the surface of the other side of the rotating base 2. A spring is provided between the pull pin 31 and the rotating base 2 to squeeze the friction plate 32, thereby fixing the two rotating bases 2.

[0035] Two rotating bases 2 form an adjustable angle through a locking mechanism 3 to accommodate the fixing needs of different parts, such as bent arms or bent legs. Pull pin 31 is slidably connected to one side of the rotating base 2, and the bottom friction plate 32 is in contact with the surface of the other side of the rotating base 2. Spring squeezes the friction plate 32 to generate friction force to fix the relative position of the two bases. Pulling pull pin 31 can overcome the spring force, unlock and adjust the angle. After release, it automatically resets and locks.

[0036] The sliding locking mechanism 11 includes a locking handle 111, which is mounted on the mounting housing 114. The locking handle 111 is rotatably connected to the mounting housing 114 via a rotating pin. A slide rod 113 is fixed on the inner wall of the mounting housing 114. A slide groove is provided on the surface of the slide rod 113. A sliding locking block 112 is provided on the slide rod 113. The slide rod 113 slides through the slide groove and cooperates with the sliding locking block 112. A spring is provided between the sliding locking block 112 and the mounting housing 114. The locking handle 111 contacts the sliding locking block 112. By rotating the locking handle 111, the sliding locking block 112 is driven to slide and lock along the slide rod 113. A rack is provided on the rotating base 2. The bottom extension end of the sliding locking block 112 can engage with the rack on the rotating base 2 to limit the sliding of the support mechanism 1 on the rotating base 2.

[0037] Support mechanism 1 can slide and adjust the spacing on rotating base 2. Locking mechanism 3 ensures that it does not shift after being fixed. Locking handle 111 rotates to drive sliding locking block 112 to slide along slide rod 113. The bottom extension of sliding locking block 112 engages with rack and pinion of rotating base 2 to restrict the sliding of support mechanism 1. The spring on it ensures that the locking block is in the default engaged state. The handle needs to be actively rotated to unlock.

[0038] The device mainly consists of two rotating bases 2, a locking mechanism 3, a support mechanism 1 and a sliding locking mechanism 11. By adjusting the included angle of the rotating bases 2 and the distance between the support mechanism 1, the device can provide fixed support for the patient's arms or legs.

[0039] Example 2:

[0040] Please see Figure 1-8 This utility model provides a technical solution: an easily adjustable emergency bandaging support device, the support mechanism 1 includes a support block 13, elastic rollers 12 are installed on both sides of the support block 13, and a tightening strap 14 is provided on the elastic rollers 12 to fix the patient's arm or leg on the support block 13.

[0041] A slider 131 is provided on the support block 13, and the support block 13 and the slider 131 are slidably connected. A spring rod 132 is provided between the slider 131 and the support block 13. Both ends of the elastic roller 12 are provided with sliders 131 and spring rods 132 to drive the elastic roller 12 to slide relative to the support block 13, thereby reducing the gap between the patient's arm or leg and the support block 13.

[0042] When adjusting the base angle, pull the pull pin 31 of the locking mechanism 3 to adjust the two rotating bases 2 to the required angle. After release, they will automatically lock. When adjusting the support spacing, slide the support mechanism 1 to the appropriate position, rotate the locking handle 111 to make the sliding locking block 112 engage the rack and pinion, fix the spacing, place the patient's limb between the elastic rollers 12, and fix the tension band 14 with Velcro. The elastic rollers 12 adapt to the shape of the limb, and the slider 131 further fits and fixes the limb.

[0043] The elastic roller 12 includes a rotating cylinder 121, with connecting blocks 122 on both sides of the rotating cylinder 121. The rotating cylinder 121 and the connecting blocks 122 rotate together. A torsion spring 123 is fixed between the two connecting blocks 122. A torsion block 124 is fixed on the torsion spring 123. The torsion block 124 is fixedly connected to the rotating cylinder 121.

[0044] The elastic roller 12 provides elasticity through the torsion spring 123. The connecting blocks 122 on both sides are rotatably connected to the rotating cylinder 121 to adapt to the shape of the limb. The slider 131 and the spring rod 132 form a sliding limit mechanism to drive the elastic roller 12 to fit the limb and reduce gaps. The tightening strap 14 is made of soft and elastic polyurethane fabric, and the Velcro connector quickly fixes the limb to prevent slippage.

[0045] The tension band 14 is made of polyurethane fabric. The tension band 14 has Velcro at the joint to connect the two ends of the tension band 14 to fix the patient's arm or leg.

[0046] Both the locking mechanism 3 and the sliding locking mechanism 11 adopt a spring reset design, which can be operated with one hand and achieve quick adjustment. The elastic roller 12 and the sliding limit mechanism reduce the fixing gap, improve stability, and achieve self-adaptive fit. The polyurethane tightening band 14 and Velcro avoid pressure, making it suitable for quick fixation in emergency scenarios, which is safer and more comfortable. The device achieves multi-angle and multi-spacing adjustment through modular design, taking into account both stability and ease of operation. It is suitable for rapid fixation and support of limb fractures or injuries in emergency scenarios.
