Description

Technical Field

[0001] The invention relates to the technical field of medical devices, and in particular to a subcutaneous emphysema negative suction device and a control method. Background Art

[0002] Subcutaneous emphysema is a potential complication after thoracic surgery. Subcutaneous emphysema refers to the process or phenomenon of relatively high gas pressure entering the subcutaneous tissue, manifesting as subcutaneous bulging and subcutaneous depression, often accompanied by symptoms such as dyspnea, cough, and chest pain.

[0003] There are many causes of subcutaneous emphysema, mainly including the following: tension pneumothorax. Tension pneumothorax is a common cause of subcutaneous emphysema in the chest. Due to the high chest cavity pressure in tension pneumothorax, the gas is absorbed through the pleura into the subcutaneous part of the chest wall, forming subcutaneous emphysema of the chest wall. This is a specific manifestation of tension pneumothorax and needs to be treated as soon as possible to prevent further deterioration of the condition; iatrogenic causes. In general surgery, especially laparoscopic surgery, gas needs to be injected into the abdominal cavity to create a surgical field of view. These gases can be absorbed through the peritoneum and enter the subcutaneous tissue, leading to subcutaneous emphysema, but usually this subcutaneous emphysema is not serious and can be absorbed by itself within a few days; trauma or infection. Subcutaneous emphysema may also be caused by gas entering the subcutaneous tissue due to trauma or infection. For example, rib or sternum fractures may cause pneumothorax, and then gas enters the subcutaneous tissue through the damaged area. Certain bacterial infections can also produce gas and enter the subcutaneous tissue, leading to infectious emphysema; drastic pressure changes. When the human body is subjected to drastic pressure changes, such as during diving, the gas in the body may diffuse into the subcutaneous tissue and form subcutaneous emphysema.

[0004] Most cases of emphysema are self-limited and do not require special treatment, but some cases may expand rapidly and massively, seriously interfering with the airway and endangering life. The main risk of subcutaneous emphysema is the rapid accumulation of large amounts of air in the deep fascial plane at the thoracic inlet. Therefore, the large amount of accumulated air can compress the trachea and large blood vessels, seriously affecting the airway, venous return, and blood flow to the head and neck.

[0005] At present, there are some methods for treating subcutaneous emphysema, such as needle aspiration, insertion of small-hole catheters, insertion of chest tubes, and multiple skin incisions for "exhaustion". Recently, negative pressure wound therapy has become an effective treatment method for various wounds ranging from simple wounds to complex suppurative wounds. Vacuum equipment extracts liquid from wounds through negative pressure gradients, which plays a huge role in reducing edema. However, the existing negative suction device has the problem of unobstructed exhaust incisions during use, which causes inconvenience in use. Therefore, a subcutaneous emphysema negative suction device and a control method are proposed to solve the above problems. Summary of the invention
