Description

Technical Field

[0001] The utility model relates to the technical field of medical instruments, in particular to a nasogastric tube fixing and anti-falling structure. Background Art

[0002] For patients with gastrointestinal decompression and dysphagia, indwelling nasogastric tube is a common nursing technique. The nasogastric tube is inserted through the nostrils, through the pharynx, through the esophagus to the stomach, and is used to extract the patient's gastric juice or inject liquid into the stomach to provide the patient with necessary food and nutrition.

[0003] However, it still has the following disadvantages in actual use:

[0004] When the existing nasogastric tube is inserted into the patient's stomach through the nostrils, it needs to be fixed to prevent the nasogastric tube from detaching from the stomach. Usually, tape is used to stick the outer end of the nasogastric tube near the bridge of the nose. Since the human body secretes sweat, the adhesion of the tape will gradually deteriorate, and the fixing effect is poor. Utility Model Content

[0005] The purpose of the utility model is to provide a nasogastric tube fixing and anti-falling structure to solve the problem proposed in the above background technology that when the existing nasogastric tube is inserted into the patient's stomach through the nostrils, it needs to be fixed to prevent the nasogastric tube from falling off from the stomach. Usually, the outer end of the nasogastric tube is adhered to the vicinity of the nose bridge with tape. Since the human body secretes sweat, the adhesion of the tape will gradually deteriorate, resulting in a poor fixing effect.

[0006] In order to solve the above technical problems, the utility model is realized by the following technical solutions:

[0007] The utility model is a nasogastric tube fixing and anti-falling structure, comprising:

[0008] A nasogastric tube assembly, the nasogastric tube assembly comprising a tube body;

[0015] Furthermore, it also includes a movable assembly, which includes a hollow annular groove, a movable column, a disc, a clamping block and a magnetic block;

[0016] A hollow annular groove is opened on the inner side of the lower end of the support tube, a movable column passes through the outer side of the lower end of the support tube and extends outward, a disc is fixedly connected to the outer end of the movable column, a clamping block is fixedly connected to the inner end of the movable column, and a magnetic block is fixedly connected to both ends of the inner side of the clamping block.

[0017] Furthermore, the clamping block is an arc-shaped structure, and the inner side surface of the clamping block fits with the outer side surface of the tube body.

[0018] Compared with the prior art, the advantages of the present invention are:

[0019] 1. The utility model sets a fixing component, and by rotating the swivel downward, the swivel gradually moves from the front end of the movable block to the rear end of the movable block. The movable block at the front end moves outward under the elastic force of the telescopic spring, driving the support block to move outward, so that the outer side of the support block fits the inside of the nasal cavity, and the swivel is located outside the nasal cavity, so that the fixing component is fixed in the nasal cavity, thereby fixing the nasogastric tube. The operation is simple and the fixing effect is good.

[0020] 2. Based on the first beneficial effect, by setting up a movable component, the position of the fixed component on the outer surface of the tube body can be changed according to the length from the user's nasal cavity to the stomach, so as to meet the use of different patients and have a wide range of applications.

[0043] The bottom end of the telescopic spring 25 is fixedly connected to the outer surface of the front end of the sleeve 21, and the movable block 23 is an arc-shaped structure;

[0044] When the movable block 23 and the support tube 22 are aligned, the telescopic spring 25 is in a compressed state;

[0045] Working principle: when it is necessary to fix the nasogastric tube inserted into the patient, a rotational force is applied to the swivel 26 to rotate the swivel 26 to the front end position of the movable block 23. At this time, the swivel 26 limits the movable block 23, so that the movable block 23 and the support tube 22 remain flush, and drive the telescopic spring 25 to be compressed, and apply a forward moving force to the support tube 22, so that the support tube 22 drives the support block 24 through the movable block 23 to enter the patient's nasal cavity. At this time, a reverse rotational force is applied to the swivel 26 to make the swivel 26 move backward along the movable block 23. At this time, the movable block 23 at the front end moves outward under the elastic force of the telescopic spring 25, driving the support block 24 to move outward until it fits with the inside of the patient's nasal cavity. At this time, the force applied to the swivel 26 is stopped, the support block 24 is located inside the nasal cavity, and the swivel 26 is located outside the nasal cavity, so that the support tube 22 is fixed in the nasal position, thereby completing the fixation of the tube body 11.

[0051] When the two sets of magnetic blocks 35 are attracted to each other, the inner side surface of the clamping block 34 and the outer side surface of the tube body 11 are in contact with each other;

[0052] Working principle: When the fixing assembly needs to be fixed in the patient's nasal cavity, an outward force is applied to the disc 33, the disc 33 drives the movable column 32 to move outward, the movable column 32 drives the clamping block 34 to move outward, and the magnetic block 35 is separated under the drive of the clamping block 34. At this time, the clamping block 34 does not contact the outer surface of the tube body 11, and the fixing assembly can be moved;
