Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of medical devices, and particularly relates to a device for abdominal cavity and abdominal wall drainage. Background Art
[0002] Abdominal cavity drainage is a commonly used treatment method for patients with abdominal effusion caused by abdominal trauma, abdominal internal injury, abdominal tumors, etc. Especially for patients with ascites due to liver cirrhosis, abdominal puncture drainage is a relatively common treatment method. Through puncture drainage, the discomfort symptoms caused by abdominal distension in patients can be improved, and the probability of abdominal cavity infection can be reduced. Generally, the abdominal puncture site is selected around the umbilicus or under the right costal margin. Such puncture points are relatively safe, easy to locate, and will not damage large blood vessels, and the drainage effect is also relatively good.
[0003] For patients with severe liver cirrhosis, uncontrollable ascites, refractory ascites or high abdominal cavity pressure, the main purpose of placing an abdominal cavity drainage tube is to relieve the pressure of the abdominal cavity. It is necessary to periodically drain an appropriate amount of ascites at intervals within a certain period of time. The amount of ascites drained every day depends on the cause of liver ascites and the severity of liver ascites. The amount of water drained every day ranges from 1000 ml, 2000 ml, 2500 ml or 3000 ml. Excessive drainage may cause symptoms such as weight loss, edema and fatigue, and may even cause complications such as hepatic encephalopathy, electrolyte disorder, infection, peritonitis, hepatorenal syndrome, etc.
[0004] In addition, during abdominal cavity drainage, fluid leakage will also occur around the abdominal wall of the drainage tube to varying degrees. Currently, during abdominal cavity drainage, for the abdominal wall fluid leakage, medical gauze is mainly used to absorb the fluid at the drainage wound. When the amount of abdominal wall fluid leakage is large, the medical gauze needs to be replaced in a timely manner many times, which increases the workload of medical staff, and the fluid leakage is likely to cause inflammation or infection of the patient's drainage wound.
[0005] Therefore, it has become a problem that needs to be solved in the industry to provide a device that can control the drainage volume of the abdominal cavity drainage tube after abdominal cavity drainage and can continuously collect the fluid leakage from the abdominal wall drainage wound at the same time.
