Novel gastroenterological clinical bidirectional-pressure gastric lavage device

Abstract

The invention discloses a novel gastroenterological clinical bidirectional-pressure gastric lavage device, comprising a mounting box. A vacuum pump, a waste liquid box, a pressure pump and a liquid storage box are arranged in the mounting box. The vacuum pump is connected with the waste liquid box through a duct. The pressure pump is connected with the liquid storage box through a duct. The wasteliquid box is connected with a waste quid incoming pipe. The liquid storage box is connected with a liquid outgoing pipe. The waste liquid incoming pipe and the liquid outgoing pipe are connected witha tee through a duct. The waste liquid incoming pipe is provided with a first electromagnetic valve. The liquid outgoing pipe is provided with a second electromagnetic valve. A pressure sensor is arranged in each of the waste liquid box and the liquid storage box. The surface of the mounting box is provided with a PLC (programmable logic controller). The novel gastroenterological clinical bidirectional-pressure gastric lavage device has the advantages that the liquid storage box is pressurized through the pressure pump so that liquid incoming speed is increased; the vacuum pump depressurizesthe inside of the waste liquid box so that liquid discharging speed is increased; therefore, gastric lavage speed is increased, operation is facilitated for medical staff.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a novel bidirectional pressurized gastric lavage device for clinical use in gastroenterology. Background technique [0002] An operation often performed by medical staff during gastric lavage in the Department of Gastroenterology. Gastric lavage refers to pouring a liquid of a certain composition into the gastric cavity, mixing the gastric contents and then withdrawing it. Unabsorbed poisons or cleaning the gastric cavity are clinically used for gastric surgery and pre-examination preparations. Most of the current gastric lavage operations use one-way pressurization, which is not only time-consuming and laborious, but also slow, which is not convenient for medical personnel. use. Contents of the invention [0003] The technical problem to be solved by the present invention is to overcome the existing defects and provide a new bidirectional pressurized gastric lavage de...
