Abstract
The invention discloses an airflow negative pressure type pancreatic-trauma peritoneal-irrigation device which comprises a drainage connector, a handle and a negative pressure system. The drainage connector comprises a negative pressure pipe located at the center and multiple built-in air supplementing pipes distributed on the periphery of the negative pressure pipe and is provided with a water supplementing pipe parallel to the negative pressure pipe. The middles of the air supplementing pipes inwards converge to form convergence pipes, and through holes are formed in the surface of the built-in convergence sections of the convergence pipes. Grooves are formed among the adjacent convergence pipes. The inner ends of the convergence pipes are simultaneously gathered to the inner end of the negative pressure pipe. The negative pressure system of the airflow negative pressure type pancreatic-trauma peritoneal-irrigation device provides a drive force through the negative pressure pipe for continuous air exhaust. Negative pressure is formed in the sunken region of the pipe wall when airflows pass through the convergence pipes in the process that the airflows passing through an externally-arranged air supplementing pipe flow towards the negative pressure pipe, and accordingly the airflows can carry a peritoneal fluid into the negative pressure pipe. The grooves have the effects of collecting and storing the peritoneal fluid and enable the peritoneal fluid to be gathered and to cover the through hole regions of the convergence pipes so as to facilitate drainage.
