Stomach tube

Abstract

The invention discloses a stomach tube. The problem is solved that because all nursing personnel master the pull-out or plug-in length of a current stomach tube by themselves according to personal nursing experience and lack uniform operation specifications and operation rules when pulling out and plugging in the stomach tube, the esophageal mucosa or the gastropore mucosa is easily damaged due to the too small or too large plug-in length of the stomach tube. According to the technical scheme, the stomach tube further includes a positioning sleeve, wherein a stomach tube body is sleeved with the positioning sleeve; an inlet and an outlet which coordinate with the stomach tube body to make the stomach tube body get through are formed in the front and rear side walls of the positioning sleeve respectively; a distance detector is arranged in the positioning sleeve and is connected with a drive mechanism controlled by the distance detector; the drive mechanism is connected to a distance indicating mechanism. By the adoption of the stomach tube, it is convenient for the nursing personnel to accurately master the pull-out or plug-in length of the stomach tube, and the situation is avoided that because the stomach tube is incorrectly plugged in, the esophageal mucosa or the gastropore mucosa is damaged.

[0003] In actual use, in order to prevent the gastric tube from pressing against the mucous membrane of the human esophagus or gastric tract, the nursing staff needs to pull out or insert the gastric tube at a certain distance regularly. For example, the nursing staff removes the gastric tube by 1.0cm to 2.0cm in the morning At night, insert the gastric tube 1.0cm to 2.0cm, so as to effectively prevent the gastric tube from oppressing the mucous membrane of the esophagus or gastric tract for a long time and causing it to be damaged. The personnel are all based on their nursing experience, and they master the length of gastric tube removal or insertion. There are great irregularities and risks in this operation process. If it is too long or too short, it will cause damage to the mucous membrane of the esophagus or stomach, which will lead to more difficult and difficult nursing work, and there is still room for improvement
