Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and in particular to an anti-falling-off gastric tube device. Background Art

[0002] A gastric tube is a tube inserted into the human stomach through the mouth or nose. It can be used for feeding and excreting gastric and intestinal fluids. For patients who cannot take food orally, a gastric tube is an indispensable treatment method. However, the detachment of a gastric tube can sometimes cause great harm to the patient, such as the need for re-insertion of the tube, increasing the patient's pain and medical costs, and even causing infection and other complications.

[0003] The existing gastric tube fixing and anti-falling device usually uses adhesive tape to stick the gastric tube to the face at one end inserted into the nasal cavity. Not only is the operation procedure cumbersome, it requires multiple tearing and pulling of the adhesive tape for sticking and fixing, but it is also easily stained by the patient's sweat, causing the adhesive tape to become non-sticky and fall off. Moreover, long-term sticking of the adhesive tape may cause discomfort to the patient's face. Therefore, it is necessary to propose an anti-falling gastric tube device. Summary of the invention

[0004] The purpose of the present invention is to solve the shortcomings of the prior art that the adhesive tape needs to be torn off multiple times for sticking and fixing, and the adhesive tape is easily stained by the patient's sweat, causing it to become non-sticky and fall off, and long-term sticking of the adhesive tape may cause discomfort to the patient's face, and an anti-falling gastric tube device is proposed.

[0009] The inner side of the arched groove is slidably connected to the first arched rack, and the inner side of the arched groove is slidably connected to the second arched rack. A gear is fixedly connected to one end of the rotating rod close to the arched block, and the gear and the first arched rack are meshed, and the gear and the second arched rack are meshed. The rotation of the gear can control the relative extension of the first arched rack and the second arched rack. By rotating the rotating rod, the first arched rack and the second arched rack can be adjusted to a suitable position.

[0010] A sliding groove is provided on the inner side of the fixed block, the inner side of the sliding groove is rotatably connected to the threaded rod, the threaded rod and the moving block are threadedly connected, and the threaded rod is rotated, and the rotation of the threaded rod can drive the moving block to move back and forth on the inner side of the sliding groove.

[0012] One end of the flexible bandage away from the first movable rod is fixedly connected to the second movable rod, and both ends of the second movable rod are commonly fixedly connected to the first connecting block. The end of the first connecting block away from the second movable rod is fixedly connected to the flexible cover. The function of the second movable rod is to connect the flexible bandage and the first connecting block, and the function of the first connecting block is to connect the second movable rod and the flexible cover.

[0013] The outer side of the flexible cover is symmetrically fixedly connected with a U-shaped block, and the outer sides of the two groups of U-shaped blocks are movably connected to the bidirectional threaded rods, and the bidirectional threaded rods and the movable plates are threadedly connected. There are two groups of movable plates, and the function of the U-shaped block is to connect the flexible cover and the bidirectional threaded rods, and the bidirectional threaded rods can rotate on the outer side of the U-shaped block.

[0014] The end of the movable plate away from the bidirectional threaded rod is fixedly connected with a second connecting block, and the outer side of the second connecting block is fixedly connected to the clamping plate. The function of the second connecting block is to connect the movable plate and the clamping plate. When the movable plate moves, the clamping plate will move with the movable plate.

The clamping and fixing simplifies the operation steps, and the medical staff does not need to repeatedly tear off the adhesive tape, which reduces the operation time and complexity and improves the work efficiency. Secondly, the clamping device is more stable and can effectively resist the external force impact caused by the patient's activities or turning over, which greatly reduces the risk of the gastric tube falling off and ensures the continuity and safety of treatment.

[0019] 2. In the present invention, further, by limiting the position of the gastric tube, the risk of the adhesive tape losing its stickiness and falling off due to contamination by the patient's sweat is avoided, thereby ensuring the stability and safety of the gastric tube during use. By limiting the position of the gastric tube, the discomfort on the patient's face can be effectively reduced, thereby improving the patient's comfort. BRIEF DESCRIPTION OF THE DRAWINGS
