Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, in particular to a traction structure for inserting a gastrointestinal nutrition tube. Background Art

[0002] A gastrointestinal nutrition tube is inserted through the nostrils, passes through the pharynx, and reaches the stomach through the esophagus. It is used to inject liquid into the stomach to provide the patient with necessary food and nutrition. It is mostly used for patients with esophageal diseases and is a commonly used auxiliary treatment method for esophageal diseases in clinical practice.

[0003] The insertion of the gastrointestinal nutrition tube needs to be done through the nasal cavity. Due to the stenosis of the esophagus, the insertion of the gastrointestinal nutrition tube needs to be done through the mouth. After the esophagus is dilated with a gastroscope, a guide wire is inserted. The gastrointestinal nutrition tube is inserted under the guidance of the guide wire, and then the gastrointestinal nutrition tube is pulled from the mouth through the nasopharynx to the nasal cavity.

[0004] A search revealed a patent publication numbered CN213048293U, which states that a traction mechanism for a gastrointestinal nutrition tube with good protective effect is provided. "By providing a connecting mechanism and a gastrointestinal tube body, after the gastrointestinal tube body is plugged into the connecting groove, the traction rope is pulled to move the clamping block into the clamping groove. The clamping groove expands and drives the second anti-slip protrusion to contact the inner wall of the gastrointestinal tube body. This solves the problem of conventional traction methods for gastrointestinal nutrition tubes requiring through holes in the inner wall of the gastrointestinal nutrition tube, which can cause damage to the tube. The first anti-slip protrusion cooperates with the second anti-slip protrusion to effectively improve the stability of the gastrointestinal tube body after clamping, and avoids damage to the gastrointestinal tube body."

[0005] However, the above solution still has certain deficiencies in actual use. In the above solution, manual auxiliary clamping is still required for clamping the gastrointestinal nutrition tube, and manual clamping has the problem of poor stability, which in turn affects the traction effect of the gastrointestinal nutrition tube.

[0008] The reinforcement structure includes a contact mask, a hanging rope is provided on the side of the contact mask, a through-hole is opened inside the contact mask, and the nutrition tube body is overlapped with the contact mask through the through-hole;

[0009] The pipe clamping device includes a driving tube and a plug-in tube, which are threadedly connected to each other. An air pump is fixedly installed on the inner wall of the driving tube, and the air outlet end of the air pump is fixedly connected to an air injection tube. An inflatable balloon is provided at the other end of the air injection tube. The inflatable balloon is located on the inner side of the plug-in tube, and a part of the nutrition tube body located on the inner side of the plug-in tube is movably connected to the outer side of the inflatable balloon.

[0023] See also Figure 1-4 The utility model discloses a traction structure for inserting a gastrointestinal nutrition tube, comprising a reinforcement structure 1 and a nutrition tube body 3. The nutrition tube body 3 is movably connected to the interior of the reinforcement structure 1, and a tube clamping device 2 is movably inserted into the other end of the nutrition tube body 3.

[0024] The reinforcement structure 1 includes a contact mask 101, a hanging rope 102 is provided on the side of the contact mask 101, a through-hole 103 is opened inside the contact mask 101, a ball 104 is rotatably connected inside the through-hole 103, and the nutrition tube body 3 is slidably connected to the inner wall of the through-hole 103 through the ball 104.

[0025] By setting up the reinforcement structure 1, the contact mask 101 can be fitted and covered with the patient's nasal cavity using the hanging rope 102, and the ball 104 inside the through-hole 103 can make the gastrointestinal nutrition tube located inside the through-hole 103 slide and overlap, thereby enabling the gastrointestinal nutrition tube to be stably guided during the traction process, making the traction movement of the gastrointestinal nutrition tube smoother.

[0026] The pipe clamping device 2 includes a driving tube 201 and a plug-in tube 208, which are threadedly connected to each other. An air pump 202 is fixedly installed on the inner wall of the driving tube 201, and the air outlet end of the air pump 202 is fixedly connected to an air injection tube 203. The other end of the air injection tube 203 is provided with an inflatable balloon 204, and the inflatable balloon 204 is located on the inner side of the plug-in tube 208.
