Embodiment approach

[0034]As an embodiment of the present invention, the elongation rate of the side of the expansion strip 51 close to the wall of the extension tube 41 is smaller than that of the side away from the wall of the extension tube 41; It is smaller than the side away from the wall of the extension tube 41, so that the expansion strip 51 has a large degree of deformation on the side away from the wall of the extension tube 41 during inflation and expansion, and a small degree of deformation on the side close to the wall of the extension tube 41, so that the expansion strip 51 extends away from the wall. The tube 41 is bent on one side, thereby effectively allowing the evenly distributed expansion strips 51 to increase the distance between the extension tube 41 and the stomach wall.

[0035] As an embodiment of the present invention, the end of the extension pipe 41 away from the casing 4 is provided with evenly distributed first through grooves 6; the first through grooves 6 correspond...

Abstract

The invention belongs to the technical field of medical instruments, and particularly relates to a negative pressure gastric lavage device for pediatricians, which comprises a control mechanism, a connecting mechanism, a stomach tube and a driven mechanism; the control mechanism comprises a control box, an operation panel, a liquid storage tank and a dirty liquid tank; the control box is of a cavity type structure of which the top is fixedly connected with a lifting handle; a first groove is formed in one side of the control box; symmetrically designed positioning rings are fixedly connected to the side, away from the handle, of the first groove; threads are designed on the inner side of the positioning ring; the liquid storage tank and the dirty liquid tank are in threaded engagement connection with the positioning rings; a suction pump and a negative pressure pump are fixedly connected to the position, located above the first groove, of an inner cavity of the control box; the suctionpump and the negative pressure pump are communicated with the liquid storage tank and the dirty liquid tank through catheters. According to the invention, inner tubes and the outer tubes are arranged, the materials of the inner tube and the outer tube are limited, the outer tube with hard texture serves as a main body, so that the stomach tube can be extended to the stomach conveniently, the inner tube with soft texture serves as an infusion tube, and then the probability of tube blockage is reduced.

Description

technical field [0001] The invention belongs to the technical field of medical devices, in particular to a negative pressure gastric lavage device for pediatricians. Background technique [0002] Gastric lavage in the prior art is a relatively quick and convenient method for removing gastric endotoxin or cleaning the stomach wall. During gastric lavage, since the patient's stomach contains more undigested food residues, it is easy to cause problems for input and output. The pipes of children are blocked by food residues. Because of the habit of swallowing when eating and the weak digestive ability of their stomachs, it is easy for children to block the pipes frequently during gastric lavage. On the one hand, the pipes Blockage and dredging make the gastric lavage work more efficient, while longer gastric lavage can easily lead to children's emotional out of control, which brings greater obstacles to treatment. At the same time, most of the prior art will input and The outpu...
