Background technique

Patients after surgery in the hospital often leave some drainage tubes in the abdominal surgery area. This drainage tube is a hollow structure that can play the role of flushing and drainage. The purpose is to reduce peritoneal effusion and observe drainage. The properties of the fluid are used to evaluate whether there is postoperative gastrointestinal leakage or intra-abdominal infection. In case of gastrointestinal leakage, the drainage tube in the abdominal cavity can be used to instill physiological saline, and at the same time connected to a negative pressure system to flush the contaminated parts and physically reduce the bacterial load.

However, the flushing and drainage devices currently used clinically in various high-level tertiary hospitals are very simple, requiring nursing staff to manually instill normal saline into the patient's abdominal cavity, and then connect a negative pressure suction tube to the other end of the drainage tube for flushing purposes. 500-1000ml of normal saline flushing fluid will be instilled in about 30 minutes to 2 hours, and the flushing fluid needs to be replaced manually. At the same time, it needs to be calculated, the amount of flushing fluid consumed and the amount of flushing fluid drawn out by the negative pressure suction tube, for nursing work A lot of work is added to the staff. At the same time, observing the properties of the flushing fluid also requires nursing staff to be distracted and take time to observe the properties of the drainage fluid and evaluate whether there is a digestive tract leak. In actual clinical nursing work, the discovery of digestive tract leaks is often delayed Wait for the condition to change. Therefore, the present invention designs a metering system based on the change in the weight of the flushing fluid, which automatically calculates the consumption of flushing fluid and the amount of waste liquid produced, and at the same time continuously monitors the properties of the waste liquid, and promptly detects changes in the condition to prompt clinical workers.
