Embodiment Construction

[0021] The present invention will be further described below in conjunction with specific drawings and embodiments.

[0022] Such as figure 1 , figure 2 As shown, the embodiment discloses a nasointestinal tube that is convenient for judging the position of the tube, including a nasointestinal tube body 1, and a main cavity 1a for inserting a guide wire and administering drugs is opened in the nasointestine tube body 1 along the axial direction. The outlet 1b of the main cavity 1a is located on the side wall of the head end of the nasointestinal tube body 1, and a guiding slope surface 1c is provided between the outlet 1b and the main cavity 1a; The sensor 3 of the pH value, the sensor 3 is connected with a wire 2, and the wire 2 is passed through the axial threading hole 1d inside the nasointestinal tube body 1, and the rear end of the wire 2 is drawn out from the side wall of the rear end of the nasointestinal tube body 1 and A monitor 4 capable of displaying the pH value ...

Abstract

The invention relates to a nasointestinal tube facilitating judgment of an intubation position. The nasointestinal tube comprises a nasointestinal tube body, wherein a main cavity which is used for placing a guide wire and administering drugs is formed in the nasointestinal tube body along an axial direction, an outlet of the main cavity is located in the sidewall of a head end of the nasointestinal tube body, and a guiding slope surface is arranged between the outlet and the main cavity; and a sensor capable of sensing a pH value in real time is fixedly mounted on the front face of the head end of the nasointestinal tube body and is connected with a conductor, the conductor is arranged in an axial threading hole inside the nasointestinal tube body in a penetrating manner, and the rear endof the conductor is led out from the sidewall of the rear end of the nasointestinal tube body and is connected with a display capable of displaying the pH value in real time. The nasointestinal tubeis ingenious in structure, reasonable in design and convenient in use and can be used for rapidly assisting to judge whether intubation is in place or not, and disadvantages of the traditional radiography judgment that the time efficiency is poor and radioactive damage is present are effectively made up.

Description

technical field [0001] The invention relates to a tube feeding device, in particular to a nasointestinal tube which is convenient for judging the position of the tube, and belongs to the technical field of medical instruments. Background technique [0002] Severely ill patients have high nutritional risks under stressful conditions such as severe trauma and infection, and timely intervention is required. Enteral nutrition (EN), especially early enteral nutrition (EEN) implemented within 24 to 48 hours, can not only provide nutritional substrates, but also improve intestinal mucosal barrier and immune function, and maintain intestinal microecology. It is increasingly accepted and applied clinically. Some critically ill patients, such as gastroparesis, severe gastroesophageal reflux, high risk of aspiration, duodenal obstruction, gastric fistula, duodenal fistula, severe pancreatitis, etc., are not suitable for nasogastric tube Enteral nutrition therapy. For patients who ar...
