[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. 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.

[0025] See also Figure 1-4 The utility model provides a technical solution: a nasojejunal tube mirror, comprising:

[0026] A nasal tube 1, the upper end of which is connected to a connector 2 for connection, and both ends of the connector 2 are respectively provided with branch tubes 3 that can be inserted into a jejunal nutrition tube or a nasobiliary tube;

[0027] The bullet head 4 is sleeved on the end of the nasal tube 1 away from the connector 2, and a through hole 5 is opened along the surface of the bullet head 4, and the through hole 5 is connected with the nasal tube 1 and the connector 2;

[0028] The silicone sleeve 6 is embedded in the bottom of the bullet head 4 along the through hole 5. A cavity 61 is provided inside the silicone sleeve 6. An LED lamp core 7 with lighting function is inserted into the cavity 61.

[0029] The front end of the bullet head 4 is hollow, and the bullet head 4 and the nasal tube 1 are fixedly connected by medical glue. The nasal tube 1 and the connector 2 are interference fit. The entire nasal tube 1, the connector 2, the branch tube 3 and the bullet head 4 form a nasojejunal tube. The nasal tube 1 can be smoothly introduced into the gastrointestinal tract through the end of the bullet head 4. At the same time, the end of the bullet head 4 adopts a hollow design. When the hollow bullet head 4 contacts the gastrointestinal tract or throat, the hollow space therein has a small buffer, reducing the possibility of hard damage to the stomach wall and esophageal wall. At the same time, the bullet head 4 and the nasal tube 1 are connected by medical glue to ensure the connection strength of the connection and reduce the possibility of the bullet head 4 and the nasal tube 1 being separated.

[0030] The input end of the LED wick 7 is connected to a lamp holder 8, and two circular holes are provided on the surface of the lamp holder 8. A support leg 71 is provided at the connection between the LED wick 7 and the lamp holder 8, and the support leg 71 is embedded in the two circular holes. The power supply of the LED wick 7 is a button battery, and the button battery is embedded in the lamp holder 8. The rear end of the lamp holder 8 is fitted with a back cover 9, and the back cover 9 is wrapped by a silicone sleeve 6. The silicone sleeve 6 is embedded in the bullet head 4 and distributed along the bottom of the through hole 5. When the bullet head 4 is along the throat to the stomach and intestines, its LED wick 7 lights up to locate the nasojejunal tube without blind insertion, reducing the risk of intubation and reducing the pain of patients. At the same time, the power supply of the LED wick 7 is a button battery, and the button battery is embedded in the lamp holder 8. The support leg 71 of the LED wick 7 is embedded in the two circular holes of the lamp holder 8 and contacts the button battery. The LED wick 7 and the lamp holder 8 are wrapped by the full-range silicone sleeve 6 to prevent the possibility of exudate inflow, thereby ensuring the safety and rationality of the overall structure.

[0031] Working principle: For this type of nasojejunal endoscope, first start the LED wick 7, which illuminates the surface of the bullet head 4. The power source of the LED wick 7 is a button battery, and the button battery is embedded in the lamp holder 8. The legs 71 of the LED wick 7 are embedded in the two round holes of the lamp holder 8 to contact the button battery. The LED wick 7 and the lamp holder 8 are wrapped by a full-range silicone sleeve 6. At this time, the user can deliver the nasal tube 1 to the throat and stomach through the bullet head 4. The end of the bullet head 4 adopts a hollow design. When the hollow bullet head 4 contacts the stomach or throat, there is a small buffer in the hollow space, which reduces the possibility of hard damage to the stomach wall and esophageal wall. Finally, the jejunal nutrition tube or nasobiliary tube is inserted along the branch tube 3 until it is passed out from the through hole 5 for nutritional feeding and testing.
