Prior to describing FIG. 4, a description overlapping with FIG. 2 will be omitted.

4, the gastrointestinal tube 200 for supplying food is provided with a plurality of injectors 231 of the injecting section 230, There is a difference from the gastrointestinal tube 100 for feeding food according to the first embodiment of the present invention.

In order to inject or discharge air into the first balloon 121 and the second balloon 122 with a single injector 231 as described above, the tube 231a is branched so that the first balloon 121 and the second balloon 122). Air is distributed and distributed through the tube 231a due to the difference in pressure between the first balloon 121 and the second balloon 122 even when a single injector 231 is provided. And the second balloon 122 can maintain a constant internal pressure. The fixing band 231b for fixing the tube 231a is not particularly limited as long as the tube 231a can be securely fixed to the supply part 110. [

In FIG. 4, the shape of the tube 231a is assumed to be branched, for example, in the form of a y-axis. However, this is merely an example and only two tubes are provided as shown in FIG. 231, respectively.

By using the injection means as a syringe in this manner, it is possible to inject or discharge air of various capacities according to the capacity of the syringe.

7 is a block diagram illustrating an alarm means of a gastrointestinal tube for feeding food according to a fifth embodiment of the present invention.

Prior to describing FIG. 7, a description overlapping with FIG. 1 will be omitted.

7, the alarm unit 123 includes a first pressure sensor 123a, a second pressure sensor 123b, a controller 123c, a speaker 123d, and a switch (not shown) 123e.

7, it is assumed that the first pressure sensor 123a and the second pressure sensor 123b are provided in the balloon, respectively. However, this is an example only. However, if the inner pressure of the balloon can be measured, Is not particularly limited.

Accordingly, the first pressure sensor 123a measures the internal pressure of the first balloon 121 and transmits it to the controller 123c in real time or periodically. Similarly, the second pressure sensor 123b also measures the internal pressure of the second balloon 122 and transmits it to the controller 123c in real time or periodically.

In this way, the controller 123c compares the internal pressure information transmitted from the first pressure sensor 123a and the second pressure sensor 123b with a predetermined internal pressure.

It is preferable that the predetermined internal pressure is, for example, less than a critical pressure that can be damaged by injecting high pressure into the balloon. Accordingly, when the received internal pressure exceeds a predetermined pressure value, the controller 123c turns on the switch 123e to activate the speaker 123d. The thus activated speaker 123d generates an alarm sound that can be perceived by a person. If the alarm sound is generated and the internal pressure of the controller 123c does not exceed the predetermined pressure value, the switch 123e is opened to deactivate the speaker 123d. Therefore, the inactivated speaker 123d stops generating the alarm sound. Here, the switch 123e may be a two-pole switch.

Therefore, according to the fifth embodiment of the present invention, it is possible to prevent the balloon from being damaged by the alarm means 123 in advance, while preventing the balloon from blowing in excess of the pressure within the body wall.

8 is a flowchart illustrating a method of fixing a gastrointestinal tube for supplying food according to a sixth embodiment of the present invention.

Prior to describing FIG. 8, a description overlapping with the above description will be omitted.

Referring to FIG. 8, a method for fixing a gastrointestinal tube (S100) for feeding a food according to a sixth embodiment of the present invention includes the steps of injecting air into a balloon (S110), determining whether the internal pressure of the balloon exceeds a predetermined pressure value (S120), and if it exceeds, generating an alarm (S130).

A method (S100) of fixing a gastrointestinal tube for supplying food according to a sixth embodiment of the present invention, which operates as shown in FIG. 8, will be described.

First, the gastrointestinal tube for supplying food is damaged if the internal pressures of the two balloons 121 and 122 are excessive. Damage to the two balloons 121 and 122 may damage the inside of the body. Therefore, the alarm means 123 shown in FIG. 4 is provided to prevent the damage.

First, air is infused into the first balloon 121 and the second balloon 122 to inflate it (S110).

Accordingly, the internal air pressures of the first balloon 121 and the second balloon 122 rise.

On the other hand, the first pressure sensor 123a measures the internal pressure of the first balloon 121 and transmits it to the controller 123c. The second pressure sensor 123a measures the internal pressure of the second balloon 122, 123c.

Then, the controller 123c determines whether or not the transmitted internal pressure exceeds a preset pressure value (S120). The internal pressure information transmitted from the first balloon 121 and the internal pressure information transmitted from the second balloon 122 are compared with each other because the capacities of the first balloon 121 and the second balloon 122 are preferably different from each other . In addition, it is preferable that the predetermined pressure value is a pressure value at which the first balloon 121 and the second balloon 122 are not damaged.

Here, if the breakdown voltage exceeds a preset pressure value, the controller 123c turns on the switch 123e to activate the speaker 123d (S130). The activated speaker 123d generates a warning sound and continues until the switch 123e is opened by the controller 123c. On the other hand, the controller 123c opens the switch 123e when it determines that the transferred internal pressure is lower than the predetermined pressure value.

The method for fixing a gastrointestinal tube (S100) for feeding food according to the sixth embodiment of the present invention can prevent damage to the balloon in advance.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is clearly understood that the same is by way of illustration and example only and is not to be construed as limiting the scope of the invention as defined by the appended claims. It will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the present invention.
