As shown, a modified nasogastric tube 100 includes a flexible hose body 1, a main passage 2, a gas passage 3, an intake passage 4, and a irrigating passage 5. The elastic hose body 1 includes an inlet end 11, an outlet end 12, an inflator 13, a lead portion 14, and a spray portion 15. The inlet end 11 includes a main opening 111, a gas inlet port 112, an outlet port 113, and a lavage port 114. The outlet end 12 is disposed opposite the inlet end 11 and the outlet end 12 includes three openings 121 (only one is shown). The inflator 13 is disposed between the inlet end 11 and the outlet end 12, and the inflator 13 is adjacent to the outlet end 12. The lead portion 14 is disposed between the inflator portion 13 and the inlet end 11, and the lead portion 14 is adjacent to the inflator portion 13. Spray 7 M435277 The sprinkle 15 is disposed between the inlet end 11 and the take-up portion 14. The main channel 2 is disposed in the elastic hose body 1 and communicates with the main opening 111 and the opening 121, so that the user can pour food or nutrient solution into the stomach through the main channel 2 when the opening 121 is placed in the stomach. Inside, or use the main channel 2 to draw liquid or gas in the stomach. The gas passage 3 is disposed in the elastic hose body 1 and communicates with the gas filling port 112 and the inflating portion 13; wherein the inflating portion 13 is, for example, a gas chamber which is opened inside the elastic hose body 1, and the inflating portion 13 The wall of the body is thinner than the wall of the body passage 3. Therefore, when the inflated portion 13 is inserted into the stomach from the patient's nasal cavity, the user can inflate the inflated portion 13 to expand by using the inflating port 112, thereby expanding the inflation portion. The inflated portion 13 is stuck in the stomach, thereby preventing the patient from removing the modified nasogastric tube 100 by itself, effectively improving the safety of use, and reducing the burden on the medical staff. The guiding passage 4 is disposed in the elastic hose body 1 and communicates with the outlet opening 113 and the guiding portion 14 to draw the liquid in the esophagus when the inflated inflating portion 13 blocks the junction between the stomach and the esophagus (the cardia) Out. The lavage passage 5 is disposed in the elastic hose body 1 and communicates with the lavage port 114 and the spray portion 15 for spraying the medicament onto the inner wall of the esophagus to clean or treat the esophagus. The main channel 2, the gas channel 3, the extraction channel 4, and the lavage channel 5 are arranged side by side without being connected to each other. Please refer to the first, fourth, fifth and sixth figures. The fifth figure is a schematic cross-sectional view of the fourth part of Fig. D. The sixth figure is a schematic cross-sectional view of the first section C-C. As shown, the spray portion 15 has four evenly distributed spray holes 151a, 151b, 151c, 151d, and the 8 M435277 spray holes I5la, 151b, i5l (^1<:1 enable the spray portion 15 to For the efficiency of the money.j (four) through the washing channel 5 '. In other embodiments, the second product is added, so as to improve the cleaning washing channel can also be connected to two 嗔 c for more than two, the liquid in the irrigation channel can be Second = channel, so that the injection

The picture in the state of the state. As shown in the figure, when filling the human-stomach 300 (only one part of the stomach is shown in the figure), when the filling portion 13 is inflated, the user can pull the modified nasogastric tube outward. The inflated inflator 13 is placed between the stomach and the esophagus 2, and then the medicament is injected into the irrigation port 114 to allow the medicament to flow through the irrigation passage 5 to the spray portion 15' and sprayed by the spray portion 15. The esophagus of the patient's patient 'follows' because the inflator 13 closes the opening between the esophagus 200 and the stomach 300, so that the medicament will accumulate in the esophagus 200, and the user can further introduce the outlet 113 to pass the medicament through the drawing passage 4 Extracted from the draw 14 . Referring to the first and eighth figures, the first figure shows a plan view of an improved nasogastric f of another preferred embodiment of the present invention. As shown in the figure, a modified nasogastric tube 100 differs from the above-mentioned modified nasogastric tube in that the modified nasogastric tube 1 (8) includes the -infusion port 112, the disk-irrigation, the 'first port' = respectively The check valves 6, 7 are provided to prevent gas or liquid from flowing back. 9 M435277 In summary, the modified nasogastric tube of this creation has an inflated portion, so the inflating portion can be inflated in the stomach of the patient, so that the patient cannot remove the modified nasogastric tube by himself, thereby avoiding the patient's own self. The safety of the use is increased by the removal of the known nasal month and the stomach or esophagus, and further, since the medical staff does not need to reinstall the nasogastric staff as described in the prior art, the medical staff can be effectively reduced. The burden, and the patient is not good again - people suffer from pain when the nasogastric tube is inserted. Compared with the prior art, in order to avoid the spontaneous dislocation of the nasogastric tube, it is often necessary to stick a sticky tape on the patient's alar to fix the nasogastric tube, because the creation uses the replenishing part to fix the improved nasal and stomach. Tube, without the need to use adhesive tape to live; for this reason, this creation can effectively listen to the long-term use of the sticky stomach τ© fixed; comfortable and caused by the oppression of the nose. In practical practice, the improved nasogastric tube of this creation has a “portion” lavage channel and lavage Π. Therefore, when the esophagus of the patient ruptures, the user can also wash the sputum “physiological saline or antibiotics”. (antibiodcs) to irrigate the septic esophagus, and can add Contrast media to facilitate the subsequent operation of the enamel film, compared with the conventional technology, the patient is in the case of severe vomiting It is necessary to swallow the liquid containing "钡" before it can take X-ray film. The improved nasogastric tube of this creation is convenient. In the process of waiting for the sputum to illuminate, when there is a rupture of the esophagus, there is It may cause sputum and even the risk of bacteria breeding in other organs. At this time, you can use the spray part to lavage, and at the same time use the bow extraction part for suction or introduce a chest tube into the chest cavity. 10 M435277 SUCTION works to reduce the chance that the heart, lungs and other organs in the chest may be inflamed. However, when the patient is out of money, the user can also inject crease, smecta, tin Mix and correct biological eggs White # equivalent to achieve the purpose of hemostasis. / In addition, because the gastroesophageal reflux is a common disease, especially in Taiwan and the United States, the main reason is related to obesity, long-term gastroesophageal reflux, easy to cause esophagus The lower part of the junction with the stomach produces a degeneration. In the epithelium of the esophagus, a so-called Barreu, s epithelial lesion is produced. This Barrett's epithelial lesion is closely related to esophageal cancer, especially in the lower esophagus, according to Helsinki, Finland. Research by the Central Hospital of the University of Central Hospital pointed out that whether this Barrett's epithelial lesion causes esophageal cancer is mainly related to the degree of antioxidant resistance of each person. Therefore, according to this study, 'for Barrett's epithelial lesions, we can create an antioxidant environment. In order to reduce the possibility of lesions, therefore, the modified nasogastric tube of the present invention is used to introduce the esophagus into the stomach, and the inflated portion located in the stomach is inflated against the opening of the stomach and esophagus, and then sprayed by the spraying portion. Simple antioxidants such as Vitamin C or even more effective superoxide dismutase SO D (superoxide deoxidase) inhibitors or osteophytes | perelase (myel〇per〇xidase) inhibitors and the like 'thereby increasing the time the agent stays in the esophagus by the action of the plenum' to inhibit Barrett's epithelial lesions Evolving into esophageal adenocarcinoma 'successfully reduces the incidence of esophageal cancer. In addition, users can use this improved nasogastric tube to improve the rare disease that can not be relieved. This disease is a congenital disease, Xi 11 M43527 The known treatment method is to use the lead rod to blindly open the esophagus after the upper digestive tract endoscopy test. Because the lead rod is a cone with a fixed diameter, the esophagus can not be relaxed, not all of them. It is narrow, so the use of lead bars can be inaccurate and ineffective. However, using the improved nasal sputum of this creation, the developer (contrastmedja) can be injected first, and the liquid is attached to the esophageal mucosa, supplemented by instant x-ray photography (flu〇r〇sc〇py), which immediately squats. After grasping the narrow area, place the inflator

After the H is filled, it is opened to prevent the esophagus from being blindly ineffective (4) and lacking flexibility.

Patients who have placed the nasogastric tube for a long time are prone to cause reflux of the gastroesophage due to interference at the gastroesophageal junction, which in turn causes ulceration of the esophagus. The goal is to enter the operating room, hit the stomach in the stomach of the two-hole channel, and then directly feed the abdominal wall, and remove the original nose and stomach officer's but this way will cause the patient to suffer more pain And because of the risk of opening a knife. However, when the modified nasogastric tube of the present invention is used to pull up the swelling == part and catch the junction of the esophagus and the stomach, it is possible to reduce >, acid reflux, and _ complications as described above. In the treatment of gastroesophageal reflux, because the long-term gastroesophageal non-24 hours continuously make the lower esophagus - straight acid, so you can use the four instruments to _ when the patient is acidic, and then use the modified nose of this creation Stomach tube is small for food: sanding water or inhibiting acid test 'or __ protect the mucous membrane, pre-protect the esophagus, let the house: _ stomach acid _. $ is so sour to reduce the thoracic esophagus in the throat _ cleansing money, usually the patient 12 M435277 · need to drink a large amount of oxidized (four) aqueous sugar solution to determine the patient's esophagus is clean, but this magnesium oxide dextrose solution It is usually not possible to completely achieve sterility. If the patient is required to wash with a large amount of antibiotics, it will cause changes in the intestines in the posterior segment, which may cause complications such as PSEUDOMEMBRANOUS COLITIS, and the improved nose of this creation. The monthly tube can use the inflated inflating part to block the interface between the stomach and the esophagus, and then spray antibiotics on the esophagus, and simultaneously use the extraction sputum to pump out of the body, thereby avoiding the antibiotics flowing to the small intestine or the large intestine, thereby effectively preventing complications. And it will not be pumped after spraying a sufficient amount 3 minutes before surgery. It also has a protective effect in the operation of incision of the esophagus. In summary, the application of the improved nasogastric tube is innumerable. Compared with the conventional nasogastric tube, the advantages of this creation are mainly: 1. When the inflated part is placed in the stomach, The inflating portion can be infused with the inflating port to inflate the inflating portion, thereby being stuck in the stomach, thereby effectively preventing the patient from removing the modified nasogastric tube by himself. 2. The user can inject the medicine through the lavage port to spray the medicine from the spray part into the esophagus of the patient. 3. When the user directly injects the medicine into the esophagus from the mouth, the expanded inflating portion can be used to block the interface between the stomach and the esophagus, and then the medicine is taken out of the patient by the extracting portion. Among them, the spray portion and the take-up portion can be used separately, but it is preferable to use them together. 4. Since the inlet port and the irrigating port can be provided with a one-way valve, it is possible to prevent the gas or the medicament from flowing backward. As can be seen from the above-described embodiments of the present invention, this creation has the use value of 13 M435277 in the industry. However, the above description of the embodiments is merely illustrative of the preferred embodiments of the present invention, and those skilled in the art can make various other modifications and changes as described in the above embodiments of the present invention. However, all of the improvements and variations made in accordance with the present embodiment are still within the scope of the creative spirit and definition of the present invention.
