Description

Technical Field

[0001] This utility model relates to the field of medical auxiliary devices, and in particular to an inflatable spinal fixation and transport pad. Background Technology

[0002] Patients with spinal injuries require strict restriction of spinal movement during emergency transport. Traditional rigid stretchers lack cushioning, which can easily cause secondary injuries and are difficult to adapt to different body types. Ordinary vacuum stretchers lose their adjustability after being shaped and have uneven local pressure. Existing soft stretchers do not provide reliable spinal fixation and still pose a risk of displacement during bumpy transport. There is a lack of dedicated fixation modules for the head and lower limbs, and the pelvic restraint belts are poorly designed and easily loosen. Repeated use of stretchers makes disinfection inconvenient and increases the risk of cross-infection.

[0003] Therefore, an inflatable spinal fixation and transfer pad is being developed to address the above problems. Utility Model Content

[0004] To overcome the shortcomings of existing soft stretchers, such as unreliable spinal fixation, risk of displacement during transport, lack of dedicated fixation modules for the head and lower limbs, rudimentary pelvic restraint straps that are prone to loosening, and inconvenient disinfection and cross-infection after repeated use, this utility model provides an inflatable spinal fixation transport pad.

[0005] The technical implementation scheme of this utility model is as follows: an inflatable spinal fixation and transfer pad, including a frame, a first air cushion installed on the top of the frame, a head protection structure installed on the upper rear side of the first air cushion, a spine protection structure provided on the upper middle side of the first air cushion, second air cushions provided on both the left and right sides of the first air cushion, and a connecting strap provided between the second air cushions.

[0006] More preferably, the head protector structure has an indentation in the middle for better fit to the head.

[0007] More preferably, the second air cushion can be everted to adapt to different patient body types.

[0008] More preferably, a leg-clamping pad is provided on the inner side of the second air cushion to fix the patient's legs.

[0009] More preferably, the connecting strap is provided with a first snap fastener, and the second air cushion on the right side is provided with a second snap fastener, the first snap fastener and the second snap fastener cooperate to fix the connecting strap.

[0010] More preferably, an anti-friction pad is provided on the upper front side of the first air cushion, which is used to reduce friction on the inner sides of the patient's legs.

[0011] By adopting the above technical solution, compared with the prior art, this utility model has the following advantages:

[0012] This invention utilizes a high-pressure air-filled spinal support structure to create rigid support for the spine, avoiding the risk of vertebral displacement. Independent air pressure control in different areas achieves uniform support for the torso and low-pressure fixation for the lower limbs, perfectly balancing braking needs and comfort. The outward-folding second air cushion and connecting strap can adapt to various body types, and the anti-friction pad significantly reduces friction damage, providing safe and efficient transport protection for patients with spinal injuries.

[0018] The technical solutions in the embodiments of this utility model will be clearly and completely described below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0019] An inflatable spinal fixation and transport pad, such as Figures 1-4 As shown, the device includes a frame 1, a first air cushion 2 mounted on the top of the frame 1, a head protection structure 3 mounted on the upper rear side of the first air cushion 2, a recessed center in the head protection structure 3 for better head fit, a spine protection structure 4 mounted on the upper center of the first air cushion 2, second air cushions 5 mounted on both sides of the first air cushion 2, and the second air cushions 5 can be everted to adapt to different patient body shapes. A leg clamping pad 6 is mounted on the inner side of the second air cushion 5 to fix the patient's legs. A connecting strap 7 is provided between the second air cushions 5, and a first snap fastener 8 is provided on the connecting strap 7. A second snap fastener 9 is provided on the right side of the second air cushion 5. The first snap fastener 8 and the second snap fastener 9 work together to fix the connecting strap 7. An anti-friction pad 10 is provided on the upper front side of the first air cushion 2 to reduce friction on the inner sides of the patient's legs.

[0020] It should be noted that when the injured person needs spinal fixation during transport, the deflated transport pad is first laid flat on a flat surface. Medical personnel then axially move the injured person to the middle of the first air cushion 2, ensuring that their spine is precisely aligned with the position of the spinal support structure 4. The air pump is then activated for graded inflation, with the spinal support structure 4 inflating first. Its internal U-shaped airways, mimicking the contours of the spine, rapidly expand to form rigid support, tightly wrapping the injured person's spine and restricting any lateral bending or rotational movements. Simultaneously, the first air cushion 2 is inflated, and the high-toughness TPU-coated airbags expand evenly at low pressure. Through slow-release pressure technology, the injured person's torso is evenly submerged in the air cushion, achieving partial pressure support for the entire back. Next, the second air cushion 5 is inflated. Its inner leg pads 6 rise in an arc shape as the air pressure increases, automatically covering the injured person's lower limbs, both fixing the lower limbs to prevent swinging and avoiding forced extension of the knee and ankle joints, which could lead to secondary injury. After both second air cushions 5 are inflated to working pressure, the connecting strap 7 is tightened and placed over the injured person, engaging with the second locking piece 9 on the right side of the second air cushion 5 via the first locking piece 8. The system applies controllable horizontal restraint force in conjunction with the air cushion to fix the injured person in three dimensions. The airbag of the head protection structure 3 is inflated in the final stage, and its central concave area expands adaptively according to the head shape. The memory foam composite layer buffers the vibration, while the two wings on both sides restrict the head deflection. The anti-friction pad 10 located at the front edge of the first air cushion 2 is made of silicone material. After inflation, it naturally fits the inner thigh of the injured person. During the bumpy transport, the micro-friction coefficient interface reduces skin shear damage. It should be noted that the spinal protection structure 4 maintains the highest air pressure (about 40-50 mmHg) to ensure absolute spinal stability. The first air cushion 2 in the trunk area uses medium pressure (about 20-30 mmHg) to ensure comfort and ventilation. The lower limb fixation area uses low pressure (about 15-25 mmHg) to balance restraint force and blood flow. After inflation, the pad body forms a biomimetic protection system with central rigid fixation and peripheral flexible fit. After transport, it is deflated and recycled. The connecting strap 7 rolls are stored in the groove of the snap fastener. The whole process achieves rapid deployment and efficient storage.

[0021] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
