Description

Pelvis fracture fixing band

Technical Field

The invention relates to the field of medical emergency equipment, in particular to a pelvic fracture fixing band.

Background

The pelvic fracture is a serious trauma which accounts for 1% -3% of the total number of the fracture, is commonly seen in serious injuries such as car accidents, high-altitude falling and the like, is a common orthopedic fatal injury, and has the fatality rate of 5% -20% and the disability rate of 50% -60%. The death rate of open pelvic fracture can reach 50%. Hemorrhagic shock is the most common, most urgent, most serious complication, and also the leading cause of death. Sources of pelvic fracture bleeding are primarily composed of three aspects: firstly, bleeding occurs at the fracture end; secondly, bleeding due to pelvic organ injury; third, bleeding due to pelvic vascular injury. Wherein bleeding in the pelvic cavity is the main cause of hemodynamics instability of the wounded. The loose tissue in the pelvic cavity has a large space for accommodating hematocele, the open book-like pelvic fracture increases the pelvic cavity volume, and if the effective pressure compression is not formed to reduce the hemorrhage, the body can lose a large amount of blood to cause the fluctuation of the blood pressure.

In the early treatment of pelvic fracture, besides active anti-shock treatment, the fixation of the ilium wings, the sacrum, the ischium and the pubis on both sides is needed, the front ring and the back ring of the fractured pelvis are fixed, the volume of the pelvis is reduced, the secondary injury of the pelvic fracture is prevented, and the opportunity and time are provided for the further rescue of patients. When the wounded is transported to the medical treatment site from the accident site and is waiting for the operation, the wounded's injury is aggravated due to improper activity of the pelvis. At present, when a pelvis fracture patient is treated before an operation clinically, a 'triangular towel' is used as a temporary limiting measure, manual tightening is needed, the fixing strength is low, the limiting effect is limited, the pelvis fracture patient is easy to slip, and the bleeding control effect is poor. In the rescue process, the pelvic cavity volume after fracture is increased due to the fact that the two legs of a patient naturally rotate outwards, bleeding is difficult to control, and the problem is easy to ignore. Therefore, there is a critical need in the very early treatment of pelvic fractures for a pelvic fixation device that more effectively stabilizes the pelvic ring, prevents fatal secondary injury and excessive bleeding from pelvic fractures, and is also a key to saving patient life.
