Problems solved by technology

[0003] The existing gastric lavage device for internal medicine has a simple structure. Generally, two sets of syringes and two gastric tubes are used to perform injection and extraction operations. The two sets of operations are likely to cause discomfort to the patient and cause damage to the gastric mucosa. The operation is difficult and cannot be performed manually. Accurate control of the flow rate can easily cause abnormal gastric pressure in patients

Abstract

The invention discloses a medical gastric lavage device, which relates to the technical field of medical equipment. It includes a support base and a gastric lavage liquid tank. A bracket is arranged on the upper surface of the support base, and a screw is symmetrically arranged between the brackets. Both ends of the screw and the bracket are rotatably connected. The nut and the ends of the screw that are close to each other are fixedly installed with auxiliary gears, and the surface of the right side wall of the bracket is provided with a driving motor. The nut above drives the gastric lavage liquid tank to move down through the connecting rod, and the infusion tube is inserted into the drainage port through the elastic sealing ring. , the push mechanism pushes the piston to reciprocate horizontally in the piston cylinder, and transport the cleaning solution in the gastric lavage tank to the human body. After cleaning, the lower screw rotates, the nut drives the liquid storage tank to move up through the connecting rod, and the top wall of the liquid storage tank moves upward. The infusion tube is inserted into the drainage port at the bottom of the piston cylinder, and the piston moves horizontally in the piston cylinder to pump the gastric juice from the human body into the liquid storage tank. .

Description

technical field [0001] The invention relates to the technical field of medical equipment, in particular to a gastric lavage device for internal medicine. Background technique [0002] Gastric lavage is to pour a specific liquid into the stomach cavity, mix it with the reactants in the stomach cavity to dilute and discharge, and then repeat the above operation to achieve the purpose of taking out the poison in the stomach cavity. Its purpose is to remove the unabsorbed poison in the stomach or clean the stomach cavity, and it is clinically used to prepare for gastric surgery and examination. [0003] The existing gastric lavage device for internal medicine has a simple structure, and generally two sets of syringes and two gastric tubes are used to perform injection and extraction operations. The two sets of operations can easily cause discomfort to the patient and cause damage to the gastric mucosa, which is difficult to operate and cannot be operated manually. Accurate cont...
