Description

TECHNICAL FIELD

[0001] The utility model relates to medical equipment technical field especially, relate to a pelvis fixing device of preventing loosening. BACKGROUND

[0002] Pelvic fracture is a kind of serious trauma disease commonly seen in emergency, and this kind of trauma can cause a large amount of blood loss due to fracture, pelvic ring separation and vascular injury of pelvic organs, which seriously threatens the life of trauma patients. For patients with pelvic fracture, pelvic belt is usually used in the early stage after injury to avoid fracture displacement as much as possible, maintain pelvic ring stability and reduce organ damage and blood loss by increasing pelvic pressure.

[0003] However, the commonly used pelvic belt has simple structure and can only be simply tied like a multi-head abdominal belt. The pressure provided by this pelvic belt is extremely limited, and the contraction force of the pelvic belt may drop to zero with slight movement, which cannot continuously stabilize and fix the trauma site. In addition, when cleaning the anal excretion or observing the pressure condition of sacrococcygeal skin, the pelvic belt needs to be completely unfastened, which can increase the risk of re-injury of the pelvis when the patient turns over, and is not conducive to maintaining the stability of the pelvis of the patient, thereby greatly affecting the treatment effect. Secondly, the currently used pelvic belt has poor universality, and many pelvic belts have single size or length that is difficult to adjust, which cannot well adapt to the difference in pelvic shape of different patients.
