Description

Technical Field

[0001] The utility model belongs to the technical field of medical devices, and in particular relates to a nasogastric feeding instrument with taste experience. Background Art

[0002] For patients who cannot eat orally and have difficulty swallowing, such as those with advanced esophageal cancer or severe esophageal stenosis, nasogastric feeding is required, that is, inserting a nasogastric feeding tube through the nose into the esophagus and then into the stomach or duodenum. Before nasogastric feeding, the food needs to be ground into a paste with a grinder, and then a large syringe is connected to the nasogastric feeding tube connector, and the push rod piston is manually pressurized to pump water and food into the patient's stomach. The patient does not eat orally and can only inject water and food into the stomach through nasogastric feeding, thereby helping patients who cannot swallow independently to provide water and food to maintain metabolism, weight and nutrition in the body.

[0003] The existing nasogastric feeding devices have a simple structure. They all use a crushing device to crush the food and then inject it into the stomach. However, the normal digestion process is divided into three parts: the head phase, the stomach phase, and the intestine phase. The head phase is when the food has not been eaten yet, the vagus nerve is stimulated by thinking about or seeing the food to cause the secretion of digestive juices, preparing for the upcoming feeding. The stomach phase and the intestine phase are the digestion and absorption in the stomach and intestine after ingesting food, including food directly stimulating the vagus nerve to cause the gastrointestinal tract to secrete digestive juices and gastrointestinal peristalsis for mechanical crushing. Therefore, the nasogastric feeding process only has the stomach phase and the intestine phase, lacking the head phase. Since the mouth contains many digestive enzymes such as salivary amylase, and food stimulates the taste buds to bring people mental and psychological pleasure, patients who have been nasogastric feeding for a long time need to have a taste experience to help digestion and improve their mental and psychological needs.

[0021] A cover 16 for sealing the crushing chamber 3 is arranged on the top of the nasogastric outer shell 2, and a damage switch 13, a nasogastric switch 14 and a suction control switch 15 are arranged on the top of the nasogastric outer shell 2. The damage switch 13 is used to control the driving motor, the nasogastric switch 14 is used to control the nasogastric pump, and the suction control switch 15 is used to control the suction pump 9.

[0022] When using the nasogastric feeding instrument of the present embodiment for nasogastric feeding, first open the cover 16, put food and an appropriate amount of water into the crushing chamber 3, cover the cover 16, then press the broken switch 13 to start the drive motor, the drive motor drives the three-leaf cutter 4 to rotate at high speed, and mechanically crush the food. After the crushing is completed, press the nasogastric switch 14 to start the nasogastric feeding pump, which can be a peristaltic pump. The nasogastric feeding pump pumps the fluid food in the crushing chamber 3 into the nasogastric feeding tube 5, and then the nasogastric feeding tube 5 is sent into the gastrointestinal tract;

[0023] The present embodiment is also provided with an oral drainage tube 7, the diameter of which is smaller than that of the nasogastric tube 5, about 1 / 5-1 / 3. Since the diameter of the oral drainage tube 7 is small, only some liquid can flow into it. When in use, the front end of the buccal tablet 8 and the annular tube 11 are placed in the oral cavity, and the suction pump 9 is started. The liquid enters the buccal tablet 8 through the oral drainage tube 7, and then seeps out into the oral cavity from the liquid outlet hole on the buccal tablet 8. The buccal tablet 8 is a strawberry-shaped structure, which facilitates the contact of the liquid with the tongue, stimulates the taste buds, produces a euphoric feeling, stimulates the vagus nerve to secrete digestive juice and promotes gastrointestinal peristalsis. The liquid "secreted" by the buccal tablet 8 also stimulates the secretion of oral digestive juice after being injected into the oral cavity, which contains salivary amylase. The suction pump 9 sucks the oral digestive juice in the oral cavity and the injected liquid into the crushing cavity 3 through the suction tube 10 and the annular tube 11, and finally feeds it into the gastrointestinal tract through the nasogastric tube 5.

[0024] In addition, in order to avoid blockage when the liquid in the crushing chamber 3 enters the oral diversion tube 7 through the diversion channel 6, the following settings can also be made:

[0025] A filter box 17 is arranged on the nasogastric outer shell 2, and the filter box 17 is located at the end of the guide channel 6. A slot is arranged on the filter box 17, and a filter plate 18 is inserted in the slot from top to bottom. A filter screen 19 is arranged on the filter plate 18, and a handle 20 is arranged on the top of the filter plate 18. A sealing ring gasket 21 is arranged on the upper part of the filter plate 18, and the sealing ring gasket 21 can seal the gap between the filter plate 18 and the filter box 17 to prevent liquid from seeping out. The oral diversion tube 7 is connected to the filter box 17.

[0026] The fluid food in the diversion channel 6 enters the filter box 17, and the particulate matter is filtered out by the filter 19 on the filter plate 18, and the liquid enters the oral diversion tube 7. After long-term use, if the filter 19 on the filter plate 18 is blocked, the filter plate 18 can be pulled out upwards, the filter 19 can be cleaned, and the filter box 17 can be inserted back again for continued use.
