Description
Technical Field
The utility model relates to the field of medical equipment, in particular to a drainage and air guide device for subcutaneous emphysema of chest wall.
Background
Subcutaneous emphysema of the chest wall is a common complication. Especially, the incidence of chronic lung blocking diseases of chest trauma and old people is very high, and one of the common complications of IUP intubation patients is usually secondary to sternum and rib fracture with pneumothorax, is often seen in a plurality of rib fractures with pneumothorax, and can also be caused by tracheal, bronchial, lung and esophageal injuries. Post surgical procedures are also common. Occasionally secondary to endoscopic lesions. The clinical manifestations are chest distress or pain after sternum, and severe cases have jugular vein dilatation, tachycardia, dyspnea and even heart failure. The etiology is as follows: closed and open lesions of the chest are often accompanied by subcutaneous pneumatosis, and there are three general routes for air to enter the subcutaneous tissue through the affected area: firstly, when the pneumothorax is accompanied by the damage of parietal pleura, air in the thorax can enter subcutaneous tissues of the chest wall through the damaged part; when the trachea, the bronchus or the esophagus is ruptured, air can directly enter the mediastinum from the rupture opening and then spread to the neck surface and the chest subcutaneous tissue through the upper fovea of the sternum; and thirdly, air directly enters subcutaneous tissues through the body surface wound of the chest wall.
The existing treatment needs to control the gas source in time except some slight subcutaneous emphysema and limited special treatment without any special treatment, including pneumothorax drainage, and operation treatment of trachea, bronchus, lung or esophagus injury and the like. If the cause is removed in time, the subcutaneous emphysema can be absorbed within several days. The extensive or severe subcutaneous emphysema compresses the trachea, the dyspnea symptom appears and endangers the life of a patient, the condition of the patient is aggravated, the general edema is caused, the large-area subcutaneous emphysema is quick to get ill, the acute symptoms are that the general edema and the infection are caused, once the internal pressure of the mediastinum is increased, and the venous stasis of the neck are shown, the mediastinum incision drainage operation should be timely carried out. The existing subcutaneous emphysema method is that the operation is performed under local anesthesia, a transverse neck incision (the incision length is 5-6cm) at the upper edge of a sternal notch is made, muscles and fascia are separated, the front wall of a trachea is exposed, a pointer is tightly attached to the trachea wall to perform blunt separation (the periphery is extruded towards the middle) every two hours or so until the aortic arch is flat, a thick drainage tube which is not easy to collapse and is provided with multiple holes beside a tail end tube is placed, and the skin incision at the neck is loosely sutured.
In general, the limitations of the current methods are: 1. the wound needs to be repeatedly squeezed, so that the burden of a doctor is increased, and the pain of a patient is increased; 2. the repeatedly squeezed wound also needs to be repeatedly opened, so that wound infection is easily caused; 3. severe bleeding from the wound also results when squeezed; the operation scar is obvious because the operation wound is hard to heal greatly.
