Description

Technical Field

[0001] The invention relates to the technical field of gastric tubes, and in particular to a visual gastric tube used for practical training and teaching. Background Art

[0002] A gastric tube is a commonly used medical device in clinical practice. It is inserted through the nostrils, passes through the pharynx, and through the esophagus to reach the stomach. It is usually used to provide clean water, food or medicine to patients who are unable to eat through the mouth, or to detect, examine and treat the stomach of certain specific patients.

[0003] There are also teaching methods for nasogastric feeding in practical teaching, but ordinary stomach tubes are usually used for teaching. Therefore, the stomach tube is usually inserted blindly. Students do not know how many centimeters to reach the esophagus or stomach, and a lot of knowledge is memorized by rote; for example, how many centimeters to the esophagus, how many centimeters to the cardia, so the existing stomach tube is not very effective for teaching;

[0004] Therefore, in view of the technical problems described above, a visual gastric tube for practical training and teaching is urgently needed. Summary of the invention

[0009] A visualization probe is provided in the installation chamber, a micro-locator is provided on the visualization probe, a wiring harness is provided in the wiring cavity, one end of the wiring harness extends into the installation chamber and is connected to the visualization probe and the micro-locator, the other end of the wiring harness extends out from the hole, a Type-C connector is provided at the end of the wiring harness extending from the hole, and a transparent end cover is provided at the end of the installation chamber.

[0010] As an improvement, the visualization probe is provided with an annular LED light, the annular LED light is connected to one end of a wiring harness, and power is supplied to the annular LED light through the wiring harness.

[0011] As an improvement, one end of the stomach tube provided with a partition plate is evenly provided with a plurality of discharge grooves, and the discharge grooves are communicated with the delivery cavity.

[0012] As an improvement, the bottom of the discharge trough is flush with the partition plate, so as to completely discharge the conveyed objects in the conveying cavity.

[0013] As an improvement, the stomach tube is provided with a length scale, and the length scale extends from the lower end of the stomach tube to the upper end of the stomach tube.

[0014] As an improvement, the connection between the installation chamber and the transparent end cover is sealed.

[0015] The advantages of the present invention compared with the prior art are:

[0016] 1. It is equipped with a visualization probe and a micro-locator. The visualization probe can be used to observe the position of the gastric tube, and the micro-locator can be used to locate the position of the gastric tube. This is convenient for teaching, allowing students to combine theoretical knowledge with practice, and then verify each other, which can achieve better teaching results;
