Description

Technical Field

[0001] The utility model relates to the technical field of first aid fixers, in particular to a first aid fixer for pelvic and spinal injuries. Background Art

[0002] Pelvic fracture is a serious trauma, mostly caused by traffic accidents, production safety and natural disasters, with a clinical mortality rate of 50% to 60%. If it is not treated in time and the care is not appropriate, the disability rate and mortality rate will be higher. Patients with early trauma often have pain, discomfort, irritability and restlessness, and may forcibly turn over and lift their legs. During the transportation process, errors in the transportation technique may also cause large-scale movement of the trunk. It causes movement or displacement of the spine and thigh, causing bone dislocation, aggravating the condition and affecting later treatment. Therefore, when treating patients with emergency pelvic fractures, in addition to fixing and protecting the pelvis, protective measures must still be taken for the spine or lower limbs to avoid secondary injuries.

[0003] At present, there is no standardized emergency external fixation device for pelvic fractures in China. Instead, pelvic fracture external fixation plate fixators, pelvic fixation belts, waistbands, clothes and cloth are often used. Most of the above devices are independent structures and cannot take into account the fixation of the pelvis and spine at the same time. They have certain defects, including the following:

[0004] Existing pelvic fixators have the following defects: 1. General pelvic fixators protect the patient's pelvis, but lack the function of braking and protecting the spine and thighs at the same time, which is easy to cause secondary injuries due to the patient's restlessness or transportation; 2. The steel plate fixator is large in size, which is not convenient for pre-hospital emergency treatment, and affects the follow-up X-ray or CT examination after fixation; 3. Some pelvic fixators will install air bags inside to support the patient and achieve a shock-absorbing effect, but the air bags used in the prior art are generally integral, with strong internal air mobility. The local air bag position may not be effectively inflated due to bone compression, and the shock-absorbing and supporting effects achieved are limited.

[0005] Existing pelvic fixation belts, waist belts, clothes and cloth substitutes have the following defects: 1. Such substitutes cannot reasonably fix the ischium, pubis, distal hip, etc.; 2. Such substitutes are made of soft materials and are prone to secondary injuries when the patient is moved after fixation; 3. Such substitutes are not effective in compressing hemostasis and relieving pain.

[0006] At present, some fixators take into account the fixation of the pelvis and spine. For example, Chinese patent application No. 202210290379.9 discloses a rescue fixation device for pelvic fracture and spinal fracture, which belongs to the technical field of rescue auxiliary devices. By laying the filling liquid bag that is not filled with liquid in the assembly position to be assembled, and performing the flushing operation through the flushing valve nozzle on one side of the filling liquid bag, the filling liquid bag expanded by the flushing can fully fit the curvature of the patient's back, and then adjust the position of the rotating fixed frame. The adjusted fixed frame can meet the relative curvature adjustment between the trunk and the pelvis, which is conducive to adapting to the multi-axis adjustment adaptability of the relative support angle of the two fracture positions when the pelvis and spine are fractured at the same time, reducing the secondary injury caused by insufficient fixed limit during rescue, and realizing the multi-level limit of the fixed frame and the assembly limit seat through the meshing cooperation of the fixed tooth block and the limit tooth ring groove, the multi-axis adjustment and modular assembly fixed frame and the assembly limit seat can support and adapt patients with different body systems during rescue, meet the use needs, and improve the use effect. However, the device is mainly implemented by a hard bracket, which is mainly composed of steel plates, which affects X-ray or CT examinations; the device has a complex structure, is inconvenient to use, and cannot well meet the patient's human anatomical structure. In addition, the device lacks the function of restraining the thigh and has limitations.

[0007] Therefore, it is necessary to provide a pelvic and spinal trauma emergency fixator to solve the above technical problems. Utility Model Content
