Abstract
Description
Technical Field
[0001] This utility model relates to a nasojejunal tube kit, belonging to the field of medical devices. Background Technology
[0002] For patients who are bedridden for a long time and have swallowing difficulties, nasojejunal tube feeding can reduce the risks of reflux and aspiration.
[0003] Nasojejunal tube feeding is simple and easy to perform, but frequent tube changes pose many challenges for both doctors and patients. Currently, commonly used methods for tube changes in clinical practice include endoscopy, X-ray, electromagnetic guidance, ultrasound-assisted insertion, and blind insertion. Endoscopic tube changes require a specialist physician, and some patients cannot tolerate endoscopic guidance due to their condition. X-ray fluoroscopy-guided tube changes have the disadvantage of subjecting both doctors and patients to prolonged X-ray radiation. Electromagnetic guidance requires a high level of medical resources. Ultrasound-guided tube changes have poor visibility due to the presence of gas in the gastrointestinal tract, requiring the operator to possess certain professional skills. Blind insertion is often used for these patients in clinical practice. This method has low equipment requirements and is economical, but its disadvantages include difficulty in ensuring the tube tip is accurately positioned, high skill requirements for the operator, and a lower success rate.
[0004] Therefore, existing nasojejunal tube replacement methods have high requirements for operators and medical equipment. Utility Model Content

[0034] Embodiment 2
[0035] The embodiment provides a nasogastric tube kit, and the embodiment is optimized on the basis of the embodiment one to improve technical effects and refine a technical solution. Details not described in the embodiment are shown in the embodiment 1.
[0036] As one of the embodiments, the nasogastric tube 1 is made of a transparent material, such as transparent polyurethane.
[0037] As one of the embodiments, the surface of the scale guide wire 2 is coated with a hydrophilic coating, such as a polyethylene glycol (PEG) coating, a polyvinylpyrrolidone (PVP) coating, and the like. When the nasogastric tube 1 is replaced, some normal saline is injected into the nasogastric tube 1 to improve the lubricity between the scale guide wire 2 and the nasogastric tube 1.
[0038] As one of the embodiments, the nasogastric tube 1 further comprises a sub-tube end 103 adjacent to the second tube end 102, and the sub-tube end 103 is used to add a lubricant to the scale guide wire 2. As one of the embodiments, the sub-tube end 103 and the second tube end 102 form a Y-shaped tube, and the normal saline is injected from the sub-tube end 103 as a lubricant when the scale guide wire 2 is inserted into the second tube end 102.
[0039] As one of the embodiments, the identifiable scale lines are marked with different colors, and the adjacent scale lines are arranged at equal intervals, which are used to identify the positions of the scale lines, so as to reduce the probability of personnel errors, and reference is made to Figure 2 .
[0040] As one of the embodiments, the flexible tip 201 can be a J-shaped tip, and the first tube end 101 is used to prevent the J-shaped tip from damaging the intestinal tract. The outer extension of the arc-shaped bending section of the J-shaped tip is easy to pass out of the first tube end 101, but when the J-shaped tip tries to retreat from the first tube end 101, the inner extension of the arc-shaped bending section of the J-shaped tip will be stuck in the tube opening of the first tube end 101. As one of the embodiments, the total length of the nasogastric tube 1 is 125 cm, and the length of the scale guide wire 2 is 260 cm. Reference is made to Figure 2 , the scale is marked from 80 cm to 130 cm from the flexible tip 201, 80 cm is red, 90 cm is orange, 100 cm is yellow, 110 cm is green, 120 cm is blue, and 130 cm is purple. The center positions between the adjacent scale marks are marked with white. The length of the J-shaped tip is 7 cm, and the remaining part is a tough section with a relatively hard texture. As one of the embodiments, after the scale guide wire 2 is inserted into the nasogastric tube 1, it is ensured that the purple mark is located at the second tube end 102, and it can be ensured that the first tube end 101 extends out of the second tube end 102 by about 5 cm.
[0041] The flexible tip 201 is designed as a J-shaped tip, and the sharp part at the end of the tip is folded, which can avoid scratching the internal organs of the user.
[0042] As one of the embodiments, by finely controlling the J-shaped tip, the end of the J-shaped tip enters the first tube end 101, the scale guide wire 2 can be taken out while the nasogastric tube 1 is retained in the body. As one of the embodiments, a string is tied at the end of the J-shaped tip, and when only the scale guide wire 2 needs to be taken out to retain the nasogastric tube 1, the string is pulled to make the J-shaped tip contract, and after contraction, it can be taken out through the first tube end 101.
[0043] As one of the embodiments, the scale guide wire 2 further comprises a scale line part with recognizable scale lines, and the hardness and toughness of the scale line part are greater than those of the flexible tip 201. That is, the flexible tip 201 is a J-shaped tip that prevents scratching the esophagus and stomach of the user. The scale guide wire 2 has higher hardness and toughness to facilitate gradual insertion into the nasogastric tube 1.
[0044] As one of the embodiments, the length of the scale guide wire 2 is at least twice the length of the nasogastric tube 1.
[0045] Non-unique method of use: the total length of the nasogastric tube 1 is 125 cm, and the length of the scale guide wire 2 is 260 cm. The scale guide wire 2 is inserted into the old nasogastric tube 1, and the purple mark of the scale line is located at the second tube end 102, which can ensure that the flexible tip 201 extends about 5 cm out of the first tube end 101 of the old nasogastric tube 1, and the scale line at the nostril can be read through the transparent nasogastric tube 1. Remove the old nasogastric tube 1, at this time, pulling the nasogastric tube 1 may cause the scale guide wire 2 to move outward, therefore, when operating, the scale guide wire 2 needs to be stretched straight and the guide wire operating end, which is the other end relative to the flexible tip 201, is fixed, and the scale mark of the guide wire at the nostril is kept as much as possible, that is, the position of the first tube end 101 is kept relatively fixed throughout the process. The new nasogastric tube 1 is inserted along the scale guide wire 2, and the insertion depth is consistent with the old nasogastric tube; the scale guide wire 2 is slowly pulled out. The scale guide wire 2 not only plays a guiding role, but also ensures that the installed nasogastric tube 1 does not deviate, and the installation is more secure and stable. Compared with the prior art, the scale guide wire 2 with scale lines is used to make the distance of the scale guide wire 2 extending into the nasogastric tube 1 relatively fixed, so that the old nasogastric tube 1 is smoothly removed along the guide wire, the position of the flexible tip 201 is fixed, and then the new nasogastric tube 1 is inserted, the guide effect of the scale guide wire 2 is utilized to improve the success rate of tube placement, the operation is convenient and fast, and it is stable and safe.
