Abstract
Description
Technical Field
[0001] The invention relates to the technical field of fluid absorption, and in particular to a fluid absorption device used in clinical surgery. Background Art
[0002] Ascites is the fluid in the abdominal cavity. It is normal for the human body to have a small amount of ascites in its abdominal cavity. However, if there is a disease state, the amount of ascites will be larger and the nature will be different. There are many common causes of ascites, which are often seen in liver diseases. Fluid may also accumulate in the abdominal cavity during surgery.
[0003] In clinical surgery, for the absorption of peritoneal fluid, the doctor usually selects the puncture point, usually on the left side, and the patient is in a side-lying or supine position. After disinfection and anesthesia, the doctor fixes the skin at the puncture site with his left hand and holds the puncture needle with his right hand. After passing through the skin and subcutaneous tissue, there is a sudden feeling of emptiness. Then the doctor releases the wallet and uses a syringe to extract the effusion. When the peritoneal effusion is large, it is more troublesome to extract it with a syringe, and an external drainage tube is required to extract the peritoneal effusion.
[0004] However, in the prior art and this solution, when extracting peritoneal effusion, especially when there is a lot of peritoneal fluid, it is not easy to adjust the suction rate according to factors such as the pressure and viscosity of the peritoneal effusion. If the peritoneal effusion is extracted too quickly, the negative pressure in the abdominal cavity will drop sharply, and the patient's discomfort will easily increase, affecting the suction progress and effect. At the same time, there are easily many impurities in the effusion, which makes it easy for the impurities in the effusion to clog the suction pump, which will also affect the suction progress and effect. For this reason, we propose a fluid suction device for abdominal surgery. Summary of the invention
