Description

[Technical field]

[0001] This utility model relates to the technical field of gastric tubes, in particular to gastric tubes for gastroenterology. [Background technology]

[0002] Conventional gastric tubes are longer than the length from the patient's nasal cavity to the stomach, so the excess part outside the nasal cavity needs to be fixed. Normally, tape is used to fix it to the patient's face, but the adhesive strength of the tape decreases with prolonged use, and it may come off. In order to solve these problems, there is a demand for a gastric tube for gastroenterology that can be fixed more stably. Summary of the Invention

[0003] In order to solve the above-mentioned technical problems, the technical solution provided by this utility model is as follows: A gastric tube for gastroenterology, comprising a gastric tube and a gastric tube fixing component, one end of the gastric tube is inserted into a patient's nasal cavity and the other end passes through the gastric tube fixing component, the gastric tube fixing component comprises a first engagement limiting member, a second engagement limiting member and a band component, the first engagement limiting member comprises an outer case, a button, a first spring, a second spring and a fixing post, the inside of the button is inserted into the first spring and the inner end extends upward to form an integrally molded engagement protrusion, the fixing post is fixed in the outer case, and the second spring is attached to the fixing post.

[0004] The second engaging and limiting member has a bottom engaging groove, which engages with the engaging protrusion to lock the stomach tube.

[0005] Furthermore, circular holes are provided on both side surfaces of the outer case, and the outer ends of the buttons protrude to the outside through these circular holes.

[0006] Furthermore, a rectangular hole is provided at the top end of the outer case, and the bottom of the second engagement limiting member is inserted into the outer case through this rectangular hole. Then, the engagement groove at the bottom of the second engagement limiting member engages with the engagement protrusion, thereby locking the second engagement limiting member into place.

[0007] Compared with the prior art, the advantages of this utility model are as follows: In this utility model, a gastric tube is detachably connected to the first engagement limiting member via the second engagement limiting member by combining multiple components such as a first engagement limiting member, a second engagement limiting member, and a band component. The band component is then used to fix the gastric tube to the patient's head, improving stability during use of the gastric tube and preventing problems such as slipping. Furthermore, the combination of the first engagement limiting member and the second engagement limiting member allows for easy removal and installation with a single touch, making operation very simple.

[0009] The present utility model will be described in more detail below with reference to the drawings. The present utility model will be described in detail below with reference to the accompanying drawings. The gastric tube for gastroenterology of the present invention includes a gastric tube 1 and a gastric tube fixing component. One end of the gastric tube 1 is inserted into the patient's nasal cavity, and the other end passes through the gastric tube fixing component. The gastric tube fixing component includes a first engagement limiting member 2, a second engagement limiting member 3, and a band component. The first engagement limiting member 2 includes an outer case 4, a button 5, a first spring 6, a second spring 7, and a fixing post 8. The inside of the button 5 is inserted into the first spring 6, and the inner end extends upward to form an integrally molded engagement protrusion 9. The fixing post 8 is fixed in the outer case 4, and the second spring 7 is attached to the fixing post 8.

[0010] The second engagement limiting member 3 has an engagement groove 10 at its bottom, which engages with the engagement protrusion 9 to be locked. The stomach tube 1 passes through the second engagement limiting member 3.

[0011] Working Example: When actually used, the present application involves inserting one end of the gastric tube 1 into the patient's nasal cavity and fixing the band component attached to the first engagement limiting member 2 to the patient's head, thereby stably holding the gastric tube.

[0012] When removing the gastric tube, the button 5 is pressed inward by hand. When the button 5 is pressed inward, the first spring 6 is compressed, and at the same time, the engagement protrusion 9 moves inward in conjunction with the button 5. This movement disengages the engagement protrusion 9 from the engagement groove 10 at the bottom of the second engagement limiting member 3. Furthermore, the second spring 7 in a compressed state generates an upward elastic force on the second engagement limiting member 3, so that the first engagement limiting member 2 and the second engagement limiting member 3 are quickly separated. This makes it possible to quickly remove the gastric tube by simply pressing the button 5 with a single touch.

[0013] When attaching the gastric tube, the second engagement limiting member 3 is inserted from the upper end of the outer case 4 of the first engagement limiting member 2. As a result, the engagement groove body 10 at the bottom of the second engagement limiting member 3 engages with the engagement protrusion 9 in the first engagement limiting member 2 and is fixed.

[0014] The outer case 4 has circular holes 11 on both sides thereof, and the outer ends of the buttons 5 protrude from these circular holes 11 to the outside.

[0015] Further, a rectangular hole 12 is provided at the upper end of the outer case 4, and the bottom of the second engagement limiting member 3 is inserted into the outer case 4 through this rectangular hole 12. Then, an engagement groove body 10 at the bottom of the second engagement limiting member 3 engages with the engagement protrusion 9, and is locked.

[0016] The band components include a first fixing band 13 and a second fixing band 14. Both ends of the first fixing band 13 and the second fixing band 14 are fixed to the outer case 4. The first fixing band 13 is wrapped around the patient's head and fixed, and the second fixing band 14 is hung on the patient's ear, thereby firmly fixing the gastric tube. This improves the stability of the gastric tube and prevents it from slipping during fixation.

[0017] A fixed plate 15 is provided inside the outer case 4 , and the inner end of the first spring 6 is fixed to the fixed plate 15 .

[0018] Although the present utility model and its implementation modes have been described above, such description is not restrictive, and what is shown in the drawings is merely one of the implementation modes of the present utility model, and the actual application is not limited thereto. In other words, any structural aspects and embodiments similar to the technical means designed by a person skilled in the art based on the suggestions, without departing from the purpose of the creation of the present utility model, and without any originality, should all fall within the protection scope of the present utility model.
