Problems solved by technology

The head of the current guide wire is a small ball formed by the fusion of closed hairs formed on the head of the steel wire when the guide wire is made. When the guide wire is pulled to adjust the position of the gastric tube, the guide wire head may pass through the front end of the gastric tube. The outward through hole will damage the gastrointestinal tissue, which is likely to cause medical accidents; when the ordinary guide wire is pulled out of the gastric tube at the end of the guidance, it is difficult to pull out due to excessive resistance; and when the gastric pressure is too high, the gastric contents It will be ejected out of the gastric tube along the guide wire

Abstract

The invention provides a novel guide wire of a gastric tube. The novel guide wire comprises a guide wire strip. A plastic reinforcement head is further wrapped on the outside of a head of the guide wire strip, the guide wire is further provided with a handle, and the tail of the guide wire strip is connected with the handle; the lower portion of the handle is a hollow and downwardly open plug, and the plug is matched with a gastric tube joint and is used for being plugged in the gastric tube joint and connecting the handle with the gastric tube joint; and the upper portion of the inside of the handle is an injection cavity, an opening of the injection cavity is sealed by a sealing film, and the injection cavity is communicated with a hollow portion of the plug. The novel guide wire is good in lubricating effect, the plastic reinforcement head has a suspension effect, and friction between the guide wire strip and the wall of the gastric tube is reduced, so that the guide wire strip can be drawn easily; the head of the guide wire strip is effectively prevented from penetrating through an outward open hole at the front end of the gastric tube to destroy gastric and intestinal tissues; and the novel guide wire is doubly sealed under the action of the plug and the action of the sealing film of the injection cavity, and the phenomenon of reverse ejection of contents of the stomach of a patient is stopped.

Description

technical field [0001] The invention relates to a gastric tube guide wire. Background technique [0002] The guide wire of the gastric tube plays an auxiliary role in penetrating the gastric tube, pulling out the gastric tube and adjusting the position of the gastric tube, and is inserted into the lumen of the gastric tube during use. The head of the current guide wire is a small ball formed by the fusion of closed hairs formed on the head of the steel wire when the guide wire is made. When the guide wire is pulled to adjust the position of the gastric tube, the guide wire head may pass through the front end of the gastric tube. The outward through hole will damage the gastrointestinal tissue, which is likely to cause medical accidents; when the ordinary guide wire is pulled out of the gastric tube at the end of the guidance, it is difficult to pull out due to excessive resistance; and when the gastric pressure is too high, the gastric contents It will be ejected out of the...
