Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of medical devices, in particular to an anti-dislodgement gastric tube. Background Art
[0002] Gastric tubes are used to help patients who cannot swallow to deliver necessary water and food under special circumstances. Gastric tubes are generally made of polyurethane or silicone. Depending on the material, polyurethane and silicone gastric tubes should be replaced once a month. There are different specifications for thickness, length and length. Gastric tubes are divided into oral gastric tubes and nasogastric tubes. When using a nasogastric tube, in order to prevent the gastric tube from falling off and avoid the patient from being reintubated, an anti-falling mechanism is used to prevent it from falling off. However, the anti-falling mechanism and the gastric tube are fixedly connected. In order to ensure the fixing effect, the length of the gastric tube insertion must be certain. However, since different patients need different lengths of gastric tube insertion, the applicability of the gastric tube is affected. Utility Model Content

[0018] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.
[0019] Example 1: Reference Figure 1-4The annular airbag 15 is fixed on the hose 1 and the outer wall of the annular airbag 15 abuts against the connecting shell 7, which helps to ensure that the hose 1 is evenly stressed and unobstructed. A squeezing mechanism is provided on the annular airbag 15, and two connecting belts 2 are fixedly connected to the connecting shell 7. The connecting belts 2 are tied to the position of the back neck to play a fixing role, thereby preventing the gastric tube from falling off. By moving the position of the connecting shell 7 on the hose 1 and then squeezing the annular airbag 15 through the squeezing mechanism, the annular airbag 15 will expand radially under the force and abut against the hose 1, fixing the hose 1 so that the position of the connection can be adjusted according to the length of insertion, thereby ensuring the anti-slip fixing effect and improving the applicability of the device.
[0020] The extrusion mechanism includes an extrusion shell 8, which is threadedly connected to the connecting shell 7. An extrusion ring 13 is fixedly connected to the annular airbag 15. The extrusion shell 8 descends and abuts against the extrusion ring 13. By rotating the extrusion shell 8, the extrusion shell 8 and the extrusion ring 13 are in contact, squeezing the annular airbag 15, thereby radially expanding the annular airbag 15.
[0021] When fixing: by moving the position of the connecting shell 7 on the hose 1, and then squeezing the annular airbag 15 through the squeezing mechanism, the annular airbag 15 will expand radially under the force and abut against the hose 1 to fix the hose 1. The connection position is adjusted according to the insertion length, and then the two connecting belts 2 are tied together and fixed at the back of the neck.
[0022] Example 2: In Example 1, when the extrusion shell 8 is rotated, it is easy to cause the extrusion shell 8 and the connection shell 7 to separate. Figure 1-4 As another preferred embodiment of the present utility model, on the basis of embodiment 1, the extruded shell 8 is connected to a limiting rod 11 through a rotating mechanism, and a connecting sleeve 10 is sleeved on the limiting rod 11. The connecting sleeve 10 is fixedly connected to the connecting shell 7, and a limiting block 14 is fixedly connected to the limiting rod 11. By adopting the limiting rod 11 and the limiting block 14 to connect the connecting shell 7 and the extruded shell 8, the extruded shell 8 and the connecting shell 7 are prevented from separating during rotation.
[0023] The rotating mechanism includes an annular groove 9, which is opened on the extrusion shell 8. A circular ring 12 is sleeved in the annular groove 9. A fixed block 5 is fixedly connected to the circular ring 12. The fixed block 5 is fixedly connected to the limit rod 11. When relative rotation occurs between the extrusion shell 8 and the connecting shell 7, the circular ring 12 will be driven to rotate in the annular groove 9.
[0024] Example 3: Reference Figure 1-4As another preferred embodiment of the present invention, based on embodiment 1, a limiting pad 4 is fixedly connected to the connecting shell 7. The limiting pad 4 limits the connecting shell 7 and prevents the connecting shell 7 from entering the nasal cavity.
[0025] A plurality of through holes 3 are provided on both connecting belts 2. The through holes 3 are designed to improve air permeability.
[0026] Anti-slip grooves are provided on both the connecting shell 7 and the extruded shell 8 , which increase the roughness and are conducive to increasing friction, so as to facilitate the rotation of the connecting shell 7 and the extruded shell 8 .
[0027] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
