AI Technical Summary

Problems solved by technology

Existing gastric tubes generally only have one main pipe, and a suction port is provided on the end face of the main pipe. If the suction is too strong, the stomach wall will be sucked into the suction port, which will not only fail to suck out the gastric juice smoothly, but may also cause damage to the gastric mucosa. In addition, when more gastric juice is pumped, it will cause blockage of the gastric juice

Embodiment 1

[0016] Example 1, reference Figure 1-3 , A safe gastric tube, provided with a gastric tube body 1, an umbrella-shaped end 2 is provided at the inner end of the gastric tube body 1, and the small end of the umbrella-shaped end 2 is a closed end with a circular arc shape. The large end of 2 is connected to the gastric tube body 1 through a connecting rod 3. There are several connecting rods 3 along the circumference of the gastric tube body 1. The gap between adjacent connecting rods 3 constitutes a gastric juice suction port 4. Umbrella-shaped end The inner cavity of 2 constitutes a suction channel connecting the gastric juice suction port 4 and the gastric tube main body 1. A number of buffer covers 5 are provided in the circumferential direction of the inner wall of the gastric tube main body 1. The inlet end extends to the outlet end, and the buffer cover 5 is provided with a plurality of through holes 7 side by side along the axis of the stomach tube body 1.

Embodiment 2

[0017] In Example 2, the safety gastric tube described in Example 1, with graduations on the outer wall of the gastric tube body 1 from the liquid inlet to the liquid outlet.

Embodiment 3

[0018] In Embodiment 3, in the safety gastric tube described in Embodiment 1, the inner wall of the gastric tube body 1 is provided with a silicone film layer.

Abstract

A safe stomach tube is provided with a stomach tube body, wherein an umbrella-shaped end head is arranged at the inner end of the stomach tube body, the small end of the umbrella-shaped end head is a circular-arc-shaped closed end, the large end of the umbrella-shaped end head is connected with the stomach tube body through connecting rods, a plurality of connecting rods are arranged in the peripheral direction of the stomach tube body, gaps formed among the adjacent connecting rods form gastric juice suction ports, the inner cavity of the umbrella-shaped end head form a juice suction channel for communicating the gastric juice suction ports and the stomach tube body, the inner wall of the stomach tube body is peripherally provided with a plurality of buffer covers, the buffer covers extend from the inlet end of the stomach tube body to the outlet end, and the buffer covers are provided with a plurality of through holes along the axis of the stomach tube body side by side. When the safe stomach tube sucks gastric juice, the umbrella-shaped end head extend to the bottom of the stomach, gastric juice enters the stomach tube body through the gastric juice suction ports among the connecting rods and is rapidly drawn out, the stomach wall is not sucked to the suction ports due to large suction strength. When the gastric juice amount is large, dredging is performed through the through holes formed in the buffer covers, and stomach tube blockage is not caused.

Description

Technical field [0001] The invention relates to a medical device, in particular to a safe gastric tube. Background technique [0002] The gastric tube, the nasogastric tube, is mainly used to extract gastric juice, and it can also inject liquid into the stomach to provide necessary food and nutrition for the patient. The existing gastric tube generally has only one main tube, and a suction port is provided on the end of the main tube. When the gastric tube is inserted into the stomach, it may extend to the stomach wall due to inaccurate grasp, and there may be If the suction force is too strong, sucking the stomach wall into the suction port not only fails to suck out the gastric juice smoothly, but may also cause damage to the gastric mucosa. In addition, the gastric juice will be blocked due to the extraction of more gastric juice. Summary of the invention [0003] The technical problem to be solved by the present invention is to provide a gastric tube with reasonable design, s...
