[0018] The technical solution of this patent is further described in detail below in conjunction with specific implementation methods.

[0019] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0020] In the description of this patent, it should be understood that the terms "center", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the drawings, and are only for the convenience of describing this patent and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on this patent.

[0021] In the description of this patent, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", and "set" should be understood in a broad sense, for example, it can be fixedly connected or set, or it can be detachably connected or set, or connected or set in one piece. For ordinary technicians in this field, the specific meanings of the above terms in this patent can be understood according to specific circumstances.

[0022] Example 1, see Figure 1 The utility model provides a nasogastric feeding tube, comprising a drainage tube 1, one end of the drainage tube is equipped with an external interface 2 connected to the inside of the drainage tube, and the other end is closed to form a closed end. A drainage hole 3 is arranged on the drainage tube near the closed end, wherein the drainage tube, the external interface and the drainage hole can use the existing structure. In this embodiment, the applicant mainly arranges an air inlet channel 4, an air inlet connector 5 and an air bag 6 on the drainage tube; the air inlet connector is arranged at one end of the drainage tube away from the closed end and is connected to the air inlet channel; the air bag is arranged near the drainage hole and is connected to the air inlet channel. Generally, the drainage hole is arranged between the air bag and the closed end.

[0023] When the above-mentioned nasogastric tube is in use, after the patient has the nasogastric tube placed, gas or liquid can be injected into the air bag through the air inlet connector to make the air bag expand and press against the stomach wall to fix the tube, making it difficult for the tube to move, thereby effectively preventing the tube from slipping.

[0024] In the present application, the air inlet connector can use an air inlet connector with a valve, and then open the valve when inflating and deflating the airbag, and close the valve after inflation. For the convenience of operation, the air inlet connector can also use an inflation and deflation nozzle.

[0025] As a preferred solution, there are two or more drainage holes, such as three, to prevent a single drainage hole from being blocked during use and affecting the use of the nasogastric tube.

[0026] Example 2, see Figure 2 and Figure 3On the basis of Example 1, the applicant has further improved the design of the airbag, wherein the airbag comprises a first airbag 6a, a second airbag 6b and a third airbag 6c, wherein the first airbag and the second airbag are both connected to the air inlet passage, and the third airbag is arranged between the first airbag and the second airbag, and both ends of the third airbag are open and are sleeved on the drainage tube, one end is connected to the first airbag, and a first connection portion 6d is formed at the connection position, and the other end is connected to the second airbag, and a second connection portion 6e is formed at the connection position, and the first connection portion and the second connection portion are both arranged close to the drainage tube; a first weak area 6f is arranged at a portion of the first airbag located inside the third airbag; a second weak area is arranged at a portion of the second airbag located inside the third airbag, wherein the first weak area may be arranged with a thickness slightly smaller than the thickness at other positions of the first airbag, or may have a weak structure such as an indentation, and the arrangement method of the second weak area is the same as the arrangement method of the first weak area. The structure provides a first airbag and a second airbag. When in use, air is supplied to the first airbag and the second airbag, and the first airbag and the second airbag expand to form two positions against the stomach wall, thereby improving the fixing effect of the stomach tube. In addition, during use, if the inflation pressure of the airbag is too high for users who do not operate in a standardized manner, the weak parts of the first airbag and the second airbag will be destroyed first, and the gas in the first airbag and the second airbag will enter the third airbag through the corresponding weak parts to reduce the air pressure in the first airbag and the second airbag, thereby preventing the first airbag and the second airbag from bursting instantly. In addition, during use, if there is a hard block at the action site, such as a stone, the first airbag and the second airbag can be placed corresponding to the hard block when placing the drainage tube, so that the hard block is located between the first airbag and the second airbag, and then the first airbag and the second airbag are inflated so that the first airbag and the second airbag expand to clamp the hard block between the first airbag and the second airbag, and the drainage tube is pulled out to bring out the hard block; in actual production, the first airbag and the second airbag can share an air inlet channel, or the air inlet channels and air inlet connectors can be set one by one, and no specific limitation is made here.

[0027] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto.
