Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and in particular to a multifunctional intelligent gastric tube. Background Art

[0002] A gastric tube is a medical device that is inserted into the stomach through the nasal cavity or oral cavity and is used to deliver nutrients, medicine or extract gastric contents. Conventional gastric tubes are generally round tubes and are usually made of plastic. At the same time, in order to facilitate the insertion of the gastric tube into the human body and reduce discomfort to the human body, conventional gastric tubes are usually softer and easier to bend.

[0003] Since the gastric tube is easy to bend, it is very difficult to insert the gastric tube into the human body from the mouth when some patients have symptoms such as laryngeal edema. This is mainly because laryngeal edema can cause obstruction to the gastric tube, and the gastric tube is very easy to bend during the insertion process, which ultimately makes it difficult to insert the gastric tube into the human body. Based on these problems, Chinese patent CN118021621A discloses a gastric tube assembly, in which an introduction component is configured inside the gastric tube, and the introduction component can strengthen the strength of the gastric tube. Therefore, when intubating patients with special diseases, the gastric tube with enhanced strength will not bend, and the gastric tube can be inserted into the stomach more smoothly, solving the problem that conventional gastric tubes are inconvenient to insert under special circumstances.

[0004] The drug outlet of the gastric tube is set on the tube wall, so some drugs cannot accurately pass through the drug outlet and accumulate at the bottom end of the inner wall of the gastric tube, which not only affects the accurate delivery of the drugs, but also causes the drug outlet of the gastric tube to be blocked.

[0024] (4) A cavity is left between the bottom cover and the threading plate, which can be used to store excess wires. The surfaces at both ends of the inner wall of the threading hole are set to be arc-shaped, which protects the wires. When the wires need to be bent, the contact area between the arc surface and the outer wall of the wires will expand, thereby preventing the outer wall of the wires from being scratched. By setting a simple connection method between the pushing inner tube, the pipe ring and the pipe through hole, the disassembly and assembly steps of the pushing inner tube are more convenient and quick, and it is also convenient to replace and clean the pushing inner tube.

[0025] (5) The gastric tube can first fix the nose ring in the patient's nasal cavity, and then the gastric tube body can be telescoped. At this time, medical staff can control and adjust the telescopic length of the gastric tube body at any time. By setting the connection structure between the insertion rod and the insertion hole, the gastric tube body can be fixed. At this time, the gastric tube body cannot be telescoped and moved, and the gastric tube body is also prevented from falling off. BRIEF DESCRIPTION OF THE DRAWINGS
