Detailed Description

In order to make those skilled in the art better understand the technical solution of the present invention, the following detailed description will be given with reference to specific embodiments.

As shown in fig. 1, in an embodiment provided by the present invention, the gastric tube structure includes a gastric tube 11, a secondary tube 31, and a sound generator 41, the secondary tube 31 is disposed at one side of the gastric tube 11, and the extension direction of the secondary tube 31 is the same as the extension direction of the gastric tube 11; the lower end face of the auxiliary tube 31 is flush with the lower end face of the gastric tube 11, and the upper end face of the auxiliary tube 31 is close to the upper end face of the gastric tube 11 or flush with the upper end face of the gastric tube 11; the sounder 41 is provided at the lower port of the sub-pipe 31.

The embodiment of the utility model provides a stomach tube structure, it is when using, injects gas into the accessory pipe 31 from the last port of accessory pipe 31 with the syringe, and gas can sound when through vocal ware 41, when hearing the sound that vocal ware 41 sent with the stethoscope in the stomach region, can judge to put the pipe successfully, and the lower extreme of stomach tube is located the stomach promptly. It is thus clear that the utility model discloses need not to aspirate gastric content, just can realize the affirmation to the stomach tube position, solved the stomach tube position that leads to when gastric content can't be taken out problem that can't be confirmed betterly to can be applicable to nasal feeding patient's nursing at home betterly.

Further, the sound generator 41 is a single audio whistle, so that when the gas is injected into the sub-tube 31 by the syringe, the gas will make a whistle sound through the sound generator, and when the whistle sound is heard in the stomach region by the stethoscope, the successful tube placement can be judged; the whistle sound is obviously different from the sound normally produced in the human body, so that the whistle sound is convenient for a user to identify. It will be appreciated that the sound generator may also be other components which are capable of generating sounds other than those in the human body when passing gas.

Specifically, the single audio whistle is provided with a ball inside the resonant cavity 61, so that the problem that the whistle is weak and difficult to identify through the stethoscope can be well avoided. If the accurate position of the lower end of the stomach tube is not determined, the stethoscope can be used for auscultating the position of the strongest sound of the whistle, so that the position of the lower end of the stomach tube is judged.

As can be understood, the auxiliary tube 31 is arranged on the gastric tube 11, so that whether the gastric tube is successfully placed or not can be judged through the sounder at each nasal feeding. Preferably, the auxiliary tube and the gastric tube are of an integrated structure. The monophonic whistle is a whistle with one tone, and the principle and structure of sounding of the whistle are the same as those of the whistle in the prior art, as shown in fig. 2, and the details are not repeated here.

As shown in fig. 3, in another embodiment provided by the present invention, the gastric tube structure comprises a gastric tube 11, a guide wire 21, and a sounder 41, wherein the guide wire 21 is a hollow structure, and the guide wire 21 is located in the gastric tube 11; the sounder 41 is disposed at the lower port of the guide wire 21. It will be appreciated that the lower port of the guide wire is adjacent to or flush with the lower port of the gastric tube; the upper port of the guide wire is higher than the upper port of the gastric tube or is parallel and level with the upper port of the gastric tube.

The embodiment of the utility model provides a stomach tube structure, it is when using, injects into gas in to seal wire 21 with the syringe through seal wire 21's last port, and gas can sound when through vocal ware 41, when hearing the sound that vocal ware sent with the stethoscope in the stomach region, can judge to put the pipe successfully, and the lower extreme of stomach tube is located the stomach promptly. It is therefore clear that the utility model discloses need not to aspirate stomach content, just can realize the affirmation to the stomach tube position, solved the unable problem of confirming in stomach tube position that leads to when stomach content can't be taken out betterly to can be applicable to nasal feeding patient's at home nursing betterly.

It can be understood that, as in the prior art, when a gastric tube is inserted, the guide wire 21 plays a guiding role, the guide wire needs to be pulled out after the gastric tube is successfully inserted, and the guide wire 21 cannot be put back into the gastric tube 11 after the gastric tube is successfully inserted in order to avoid damaging tissues due to the fact that the guide wire penetrates out of a gastric tube side hole, so that the sounder mounted at the lower port of the guide wire 21 can only be used for position judgment during initial tube insertion.

Further, the gastric tube structure further comprises a PH test strip 51, wherein the PH test strip 51 is disposed on the outer wall of the sounder or on the outer wall of the guide wire 21 and close to the sounder 41. Because the PH test strip can change color when meeting gastric acid, whether the gastric tube is successfully placed can be confirmed again by observing the color of the PH test strip 51 after the guide wire 21 is drawn out, and nasal feeding is carried out after the gastric tube is successfully placed.

Further, the sound generator 41 is a single audio whistle, so that when gas is injected into the guide wire by the syringe, the gas will make a whistle sound through the sound generator, and when the whistle sound is heard in the stomach region by the stethoscope, the successful intubation can be judged.

Specifically, the single audio whistle is provided with a ball inside the resonant cavity 61, so that the problem that the whistle is weak and difficult to identify through the stethoscope can be well avoided.

The utility model discloses can shorten the time of judging stomach tube lower extreme position, improve the accuracy of judging the position, also be favorable to the popularization simultaneously. The utility model provides a vocal ware also can trade the chip, nevertheless because present GPS positioning error is great, so should not use at present, but when the GPS error reached centimetre level or even less rank precision, should respond out the position of stomach tube lower extreme for the chip that the chip should be more accurate with vocal ware replacement.

The above are only preferred embodiments of the present invention, and it should be noted that these examples are only used for illustrating the present invention and not for limiting the scope of the present invention, and after reading the content of the present invention, those skilled in the art can make various changes or modifications to the present invention, and these equivalents also fall within the scope defined by the claims attached to the present application.
