Ilium inflation pressure tourniquet with leg fixation

Abstract

The invention relates to an ilium inflation pressure tourniquet with leg fixation and belongs to the technical field of medical instruments. The ilium inflation pressure tourniquet comprises a waist fixing belt, a leg fixing belt and a pressurizing airbag, wherein both the waist fixing belt and the leg fixing belt are connected with the pressurizing airbag; a dissection groove matched with the upper spine of ilium is formed in the skin side of the pressurizing airbag; an air injection hole is formed in the pressurizing airbag; a bag body for holding an ice compress bag or a complete interlayeris arranged on the wall of the dissection groove; and a liquid injection hole for injecting ice compress gel is formed in the interlayer. Due to adoption of the dissection groove matched with the upper spine of the ilium, the ilium inflation pressure tourniquet has the characteristic of anterior superior spine dissection, and hemostasis parts can be accurately positioned; the dissection groove issufficiently adhered to an anterior superior spine in a wrapping manner, then wrapping support is formed, pain can be relieved to a certain extent, and the comfort can be improved; the waist fixing belt and the leg fixing belt are adopted to fix the pressurizing airbag through tensile force in multiple directions, so that the pressurizing airbag is uniformly stressed and fixed solidly, displacement of the pressurizing airbag can be effectively prevented, and the hemostasis effect can be ensured.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to an ilium inflatable pressure tourniquet with fixed legs. Background technique [0002] Repairing mandibular defects with free iliac crest grafts is one of the commonly used methods in clinical oral and maxillofacial surgery. Because the ilium has the advantages of rich cancellous bone, large bone supply, easy cutting, high survival rate, and similar curvature to the mandible, it can achieve an ideal repair effect for restoring the shape and function of the mandible. [0003] During the operation, the iliac crest is taken from the bone tissue because the osteotomy wound is bone tissue, so the traditional "suturing, clipping" and other methods cannot be used to stop bleeding. The electrocoagulation knife is used to stop bleeding, and local application of hemostatic agent is used. After surgery, a 2kg weight is usually used Sandbags or salt bags should be used to compress t...

AI Technical Summary

Problems solved by technology

[0005] 1. Because the anterior superior iliac spine is arc-shaped and hard and convex, the salt bag or sandbag does not fit well with the wound, resulting in poor compression and hemostasis;

[0006] 2. If the salt bag or sandbag is not effectively fixed, the salt bag will often be displaced when the patient turns over or dragged by the body, resulting in inability to effectively stop bleeding;

[0007] 3. The position of the salt bag or sandbag directly affects the hemostatic effect. Due to the special position of the ilium, inexperienced medical staff or patients' family members cannot place the salt bag or sandbag accurately;

[0008] 4. Patients who are compressed by salt bags need to stay in bed for a long time before the osteotomy wound heals, and pressure sores are prone to appear on the skin of the compressed area; moreover, the current use of salt bags or sandbags cannot effectively support and bandage the osteotomy wound, and the patient turns over after surgery. Such activities can cause increased local pain and poor comfort
