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 devices, in particular to a negative pressure gastric lavage device for pediatricians, which includes a control mechanism, a connecting mechanism, a gastric tube and a driven mechanism; the control mechanism includes a control box, an operation panel, a liquid storage Tank and sewage tank; the control box is a cavity structure with a handle fixed on the top; a first groove is opened on one side of the control box; a side of the first groove away from the handle is fixed Symmetrically designed positioning ring; the internal thread design of the positioning ring; the liquid storage tank and the sewage tank are threadedly connected with the positioning ring; the inner cavity of the control box is located above the first groove and is fixedly connected with a suction pump and Negative pressure pump; the suction pump and negative pressure pump communicate with the liquid storage tank and the sewage tank through conduits; the present invention makes the texture harder by setting the inner tube and the outer tube and limiting the material of the inner tube and the outer tube The outer tube is used as the main body to facilitate the extension of the gastric tube to the stomach, and the soft inner tube is used as the infusion tube to reduce the chance of tube blockage.

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...
