Abstract

The invention discloses a novel stomach jejunal tube device, which comprises a tube body internally provided with an empty cavity, an imbedding head arranged on the imbedding end of the tube body, anda pH value detection head arranged in the tube body, wherein the pH value detection head is positioned in the imbedding head; the imbedding head is provided with a plurality of through holes; the pHvalue detection head is in communication connection with a guide wire; the end part, which is far away from the imbedding head, of the tube body is provided with an opening which communicates with theinner cavity of the tube body; and the guide wire extends out of the opening and is in communication with a pH value measurement instrument. The novel stomach jejunal tube device has a reasonable structure and good use performance, due to cooperation of the pH value detection head and the pH value measurement instrument, the insertion depth of a gastrointestinal tube can be reliably detected, according to the difference of the pH values of different positions in the body of a patient, a tube body imbedding position is determined, so that a gastrointestinal tube imbedding position is judged, the defects of gastrointestinal tube blind imbedding are effectively eliminated, working efficiency and accuracy are improved, and the novel stomach jejunal tube device is convenient for medical care personnel in operation and has good use performance.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a novel gastric jejunum tube device. Background technique [0002] The existing gastric tube is usually placed in the gastric cavity by hand, and the tip of the tube is sent below the Treize ligament by the peristalsis of the stomach. It takes a long time (8-48 hours), and the improved success rate Low, it is not suitable for patients with gastric emptying disorder, and it is easy to cause complications such as respiratory tract and digestive tract damage, perforation due to blind operation. In addition, multiple X-ray positioning is required, and it is often difficult to reach the target position because the gastric tube is difficult to pass through the pylorus. The success rate of tube insertion is only 17%, and the insertion effect is poor and the usability is low. Contents of the invention [0003] The purpose of the present invention is to provide a novel gastroje...
