Description

An iliac inflatable pressure tourniquet with leg fixation

technical field

The invention relates to the technical field of medical devices, in particular to an ilium inflatable pressure tourniquet with fixed legs.

Background technique

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.

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 the bone harvesting site to stop bleeding.

The current use of saline or sandbags for hemostasis by ilium compression has the following disadvantages:

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, and then the effect of compression to stop bleeding is not good;

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 the inability to effectively stop bleeding;

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;

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 will cause increased local pain and poor comfort.

Detailed ways

In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings.

Embodiment one

As shown in Figures 1, 2, and 3, the ilium inflatable pressure tourniquet with leg fixation disclosed in this embodiment includes a waist fixation belt 1, a leg fixation belt and a pressurized air bag 2, a waist fixation belt 1 and a leg fixation belt. The fixation straps are all connected to the pressurized airbag 2, the skin side of the pressurized airbag 2 has an anatomical groove 21 adapted to the superior iliac spine, and the pressurized airbag 2 has an air injection port.

In order to enhance the hemostatic effect, as shown in FIG. 2 , a bag body 23 for placing an ice pack is provided on the groove wall of the anatomical groove 21 . Or, as shown in FIG. 3 , the groove wall of the anatomical groove 21 is provided with a fully covered interlayer 22 , and the interlayer 22 has a liquid injection port for injecting ice compress gel. When it is necessary to apply ice to stop bleeding, place an ice bag in the bag body 23; or inject ice gel into the interlayer 22 through the liquid injection port. Added ice function while applying pressure to enhance hemostasis. The area of the compression surface of the pressurized airbag 2 is set as required. When the bone harvesting wound is at the anterior superior iliac spine, the pressurized airbag 2 wrapping the anterior superior iliac spine can meet the needs; while when the bone harvesting wound is at other parts of the ilium, the compression surface of the pressurized airbag 2 is changed from the anatomical The groove 21 extends at least as far as the bone harvesting site. It can be made into different models for common bone harvesting sites in clinical practice.

In this embodiment, the pressurized airbag 2 is connected to the skin side of the waist fixing belt 1, and the two ends of the waist fixing belt 1 are detachably connected by a buckle or velcro connection, which is convenient for fixing, and can also be applied to patients with different abdominal circumferences . The leg fixing strap includes two oblique straps 3, the upper ends of which are connected to the pressurized airbag 2, and the lower ends of the two oblique straps 3 are detachably connected by buckles or gluing. It is convenient to fix, and can also be applied to patients with different leg circumferences and heights, improving its versatility.

Preferably, both the waist fixing belt 1 and the leg fixing belt are elastic bandages. The material of the pressurized air bag 2 can be selected from the same material as that of the blood pressure cuff, such as soft woven cloth or vinyl.

Below in conjunction with accompanying drawing Fig. 1-4 introduce the using method of present embodiment:

When in use, align the anatomical groove 21 of the pressurized airbag 2 with the superior ilium spine, make the superior iliac spine fall into the anatomical groove 21, make the pressurized airbag 2 wrap and cover the superior iliac spine, and then place the waist The fixing belt 1 is fixed on the waist and abdomen in a ring, and the two oblique belts 3 are respectively fixed around the inside and outside of the thigh root; the gap between the waist fixing belt 1 and the skin is adjusted to a distance that can be inserted into a finger.

Then utilize inflator 6 to inflate the pressurized airbag 2, the gas injection pipe of the inflator 6 is connected with the gas injection port of the pressurized airbag 2, and the gas injection pipe is connected with the air bag manometric gauge 7, through the inflator 6 into the pressurized airbag 2 Inflate and pressurize the airbag 2 to form a compressive force on the ilium, thereby realizing compression and hemostasis. During the gas injection process, the inflation pressure can be observed in real time through the air bag manometer 7, and the inflation can be stopped when the pressure reaches an appropriate level, so as to avoid the effect of hemostasis caused by too low pressure, and local ischemia and necrosis caused by too high pressure.

The present invention has an anatomical groove 21 adapted to the anterior superior iliac spine, which is more suitable for the anatomical characteristics of the anterior superior iliac spine, and is conducive to accurate positioning of the hemostatic site; The anatomical groove 21 of the airbag 2 is fully attached and wrapped on the anterior superior iliac spine, fully fits and compresses the wound at the bone harvesting site, the compression area is large, and the hemostatic effect is good; and the pressurized airbag 2 compresses the wound part to form a certain package and support, To a certain extent, it can relieve pain and improve comfort.

The waist fixing belt 1 and the leg fixing belt fix the pressurized airbag 2 with multi-directional tension, so that the force is more balanced and the fixation is firmer, which can effectively prevent the displacement of the pressurized airbag 2 during bed exercises such as turning over, which is conducive to ensuring the hemostatic effect ; Two pressurized airbags on the tourniquet only compress the wound part, effectively reducing the compression area, increasing the comfort of the patient, and reducing the risk of pressure sores.
