Pelvis volume control external fixation device

Abstract

The invention discloses a pelvic volume control external fixing device, and relates to the field of medical instruments, the pelvic volume control external fixing device comprises posterior pelvic trousers and anterior pelvic trousers, the posterior pelvic trousers are matched with the waist and hip of a human body, and a kidney dilatation balloon and an ischium dilatation balloon are arranged at the positions, corresponding to the kidney and the ischium of the human body, of the inner side face of the posterior pelvic trousers respectively; on the basis of the pelvic volume control theory and the self-filling effect, through a pelvic anatomy soft channel, by means of the expansion balloon at the corresponding position and through inward compression, the pelvic volume can be rapidly, simply and conveniently reduced, and under the condition that the wound of a patient is not increased, the pelvic volume of the patient can be rapidly and conveniently reduced. Pelvic volume expansion caused by serious pelvic trauma can be rapidly controlled, so that hematoma diffusion can be limited, hematoma pressure can be increased, the self-filling effect can be enhanced to control bleeding, and the life saving effect can be achieved.

Description

technical field [0001] The invention belongs to the field of medical equipment, and in particular relates to an external fixation device for controlling pelvis volume. Background technique [0002] Pelvic fractures are relatively common injuries in trauma, and the mortality rate of patients with hemodynamically unstable pelvic fractures is as high as 40-50%. Generally speaking, there are three sources of pelvic fracture bleeding, namely, pelvic venous plexus, fracture ends, and vascular injury. [0003] Studies have shown that venous injury bleeding accounts for 80% of pelvic fractures. For primary hospitals and pre-hospital first aid, timely hemostasis and reduction of blood loss can provide valuable time for saving patients' lives. At present, the simple pelvic girdle is widely used. The pelvic girdle can form blood clots and reduce bleeding while stabilizing fractures. . [0004] The mechanism of pelvic girdle fixation: (1) close the open book-like injury, reduce the v...

AI Technical Summary

Problems solved by technology

[0007] Aiming at the problem that the current measures can only prevent the secondary displacement of the broken end of the fracture, and have no more benefits for the bleeding of the fractured end and pelvic blood vessels, and cannot reduce the volume of the pelvis, the present invention provides a pelvic volume control external fixation device
