Pediatric negative pressure gastric lavage device for pediatricians

Abstract

The invention discloses a pediatric negative pressure gastric lavage device for pediatricians. The pediatric negative pressure gastric lavage device structurally comprises two filters, a machine body,a filter pipe, a control panel, a storage box and a power interface, wherein the two filters are installed on the right side of the machine body and are connected through a pipeline, a groove body inthe top end of the machine body is movably connected with a filter pipe support, the filter pipe is installed at the bottom of the control panel, a groove in the left side of the machine body is meshed with the storage box, the power interface is fixed to the bottom of the left side of the machine body, and the interior of the power interface is fixed through welding. The pediatric negative pressure gastric lavage device has the advantages that a protective upper cover is matched with a cylinder body, a direct buckling mode is adopted, and control rings are pushed downwards to enable lockingarms to extrude anti-skid inner plates on the outer surface of the cylinder body to prevent the anti-skid inner plate from sliding off; and meanwhile, whether installation is correct or not can be confirmed through comparison between the lower edges of the locking arms and scales on the side edge of the cylinder body after sealing is completed, in this way, whether the upper cover is correctly installed or not can be visually checked, besides, the upper cover is more convenient and quicker to install, and the situation that the gastric lavage efficiency is low due to the fact that the cylinderbody is not tightly covered by the upper cover is avoided.

Description

technical field [0001] The invention relates to a pediatric negative pressure gastric lavage device for pediatricians, which belongs to the technical field of medical instruments. Background technique [0002] Gastric lavage refers to pouring a certain composition of liquid into the gastric cavity, mixing the contents of the stomach and then drawing it out, and repeating this many times. Its purpose is to remove unabsorbed poison in the stomach or clean the gastric cavity. It is clinically used for gastric surgery and preparation before examination. For acute poisoning such as swallowing organic phosphorus, inorganic phosphorus, alkaloids, and barbiturates within a short period of time Gastric lavage is an important rescue measure. During gastric lavage, it needs to pass through a coarse filter. The upper cover of the filter usually adopts a spiral structure, which is prone to misalignment before the thread teeth, which will lead to When the pressure is lost, the speed slow...
