Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, in particular to a nasogastric feeding tube fixing device. Background Art

[0002] A nasogastric tube is inserted through the nostrils, through the pharynx, and through the esophagus to reach the stomach. 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] Nowadays, in the process of nasogastric feeding for patients who cannot eat independently, food is usually injected into the patient's body through a nasogastric tube, and in order to prevent the nasogastric tube from falling out, it is generally necessary to fix the nasogastric tube with a fixing device.

[0004] After searching, it is proposed in a medical nasogastric feeding tube fixing device with patent publication number CN202321612219.8 that "the medical nasogastric feeding tube fixing device described in the utility model does not need to use tape, and is double-fixed by latex protective sleeves and hanging ears, which effectively enhances the stability of the entire device, avoids accidental falling off during use, increases the comfort of use, and the nasogastric feeding tube is firmly fixed and not easy to fall off, effectively preventing the nasogastric feeding tube from moving and being pulled out, and is easy to operate";

[0005] However, the above scheme still has certain shortcomings in actual use. When the scheme is in use, the distance between the two nasal tubes is fixed. When the two nasogastric tubes are clamped at the same time, the distance between the two nasogastric tubes cannot be adjusted according to the wearing conditions of different patients, resulting in the two nasogastric tubes not being able to adapt well to the position of the patient's nostrils. If the distance is too large, it is easy to cause pulling on the patient's nostrils, resulting in low comfort level. Utility Model Content

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] See also Figure 1-4 The utility model discloses a nasogastric tube fixing device, comprising a facial wearing structure 1 and a nasogastric tube structure 2, wherein a spacing adjustment structure 3 is arranged on the inner side of the facial wearing structure 1, and the nasogastric tube structure 2 passes through the spacing adjustment structure 3 through the facial wearing structure 1; the facial wearing structure 1 comprises a mask 101, wherein a hanging rope 102 is arranged on the side end of the mask 101, and a mounting recess 103 and a through-hole 104 are arranged on the inner side of the mask 101, wherein the through-hole 104 is located below the mounting recess 103, and the mounting block 301 is connected to the mounting recess 103. The inner wall of the nasogastric tube structure 2 is movably connected; the nasogastric feeding tube structure 2 includes a tube body 201, an injection connector 203 is fixedly installed at the end of the tube body 201, and an air bag 202 is arranged near the injection connector 203 of the tube body 201, and the tube body 201 passes through the insertion tube 307 and the bending tube 308 through the through opening 104; the injection connector 203 is used to connect the syringe for liquid food delivery, and the air bag 202 is made of elastic rubber. The unobstructed state of the tube body 201 is displayed by the expansion degree of the air bag 202, which is convenient for medical staff to judge whether the tube body 201 has a blockage problem.

[0022] The spacing adjustment structure 3 includes a mounting block 301, the interior of the mounting block 301 is connected with a cross bar 302, the surface of the cross bar 302 is slidably connected with two sliders 303, a movable plate 304 is fixedly installed on the outer side of the slider 303, a hinge seat is fixedly connected to the side of the movable plate 304 close to the slider 303, and a limit pin 305 is rotatably connected to the inner side of the hinge seat, a limit notch 306 is provided on the top of the mounting block 301, and the size of the limit notch 306 is adapted to the specification of the limit pin 305, and a connecting disk 309 is fixedly installed on the side of the movable plate 304 away from the slider 303, and the connecting disk 309 is fixedly installed on the side of the movable plate 304 away from the slider 303. 09 is fixedly plugged with an insertion tube 307 on the inner side, and a bent tube 308 is provided at the bottom end of the insertion tube 307; by providing a spacing adjustment structure 3, the slider 303 can cause the cross bar 302 to drive the insertion tube 307 to move horizontally through the movable plate 304, so that the interval between the two insertion tubes 307 can be adaptively adjusted according to the patient's wearing situation, so that the nasogastric tube structure 2 can be adjusted in spacing through the spacing adjustment structure 3 located on the inner side of the facial wearing structure 1, avoiding the nasogastric tube spacing being too large and causing pulling on the patient's nostrils, so that the nasogastric tube structure 2 can adapt to the position of the patient's nostrils, thereby improving the patient's comfort.

[0023] When in use, the output end of the tube body 201 is first passed through the through opening 104 and then through the bending tube 308 and the insertion tube 307 in sequence, and then the interval between the two insertion tubes 307 is adjusted according to the patient's nostril position. The user first drives the moving plate 304 to move on the surface of the crossbar 302 through the slider 303, and after the insertion tube 307 is moved, the limiting pin 305 is screwed into the limiting notch 306, so that the moving plate 304 is now in a limiting state between the limiting pin 305 and the mounting block 301, so that the interval between the two insertion tubes 307 can be adaptively adjusted according to the patient's wearing situation;

[0024] During nasogastric feeding, a syringe for sucking liquid food is connected to the injection connector 203, and the liquid food is injected into the stomach along the tube body 201 by pushing the syringe push rod. The patency of the tube body 201 is judged by the expansion degree of the airbag 202. If the end of the tube body 201 is blocked or the middle part is bent and twisted, the liquid food cannot be smoothly introduced into the stomach. The liquid food injected into the tube body 201 supports the expansion of the airbag 202 to remind medical staff that the patency of the tube body 201 is not enough and the tube needs to be replaced.

[0025] To summarize, the nasofeeding tube fixing device, by setting up a spacing adjustment structure 3, can use the slider 303 to prompt the cross bar 302 to drive the insertion tube 307 to move horizontally through the movable plate 304, so that the interval between the two insertion tubes 307 can be adaptively adjusted according to the patient's wearing situation, so that the nasofeeding tube structure 2 can be adjusted in spacing through the spacing adjustment structure 3 located on the inner side of the facial wearing structure 1, avoiding the nasofeeding tube spacing being too large and causing pulling on the patient's nostrils, so that the nasofeeding tube structure 2 can adapt to the position of the patient's nostrils, thereby improving the patient's comfort.

[0026] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
