Examples

Referring to fig. 1, a stomach tube for digestive system department includes an insertion tube 1, an air bag a2 and an air tube 3, one end of the insertion tube 1 is set as an insertion end 101, the outer wall of the insertion tube 1 near the insertion end 101 is sleeved with an air bag B4, the inner wall of the insertion tube 1 is provided with an air introducing channel 5, the air introducing channel 5 is communicated with the inside of the air bag B4, the air bag a2 is communicated with the air introducing channel 5 through the air tube 3, and similarly, as in the prior art, the air tube 3 is also provided with a valve (not shown in the figure).

The same as the working principle of the prior art, when in operation, the medical staff firstly inserts the insertion end 101 of the insertion tube 1 into a preset position in the body of a patient from the oral cavity of the patient, opens the valve, inflates the air bag B4 by squeezing the air bag A2, and finally, the outer surface of the air bag B4 is attached to the inner wall of the esophagus of the patient along with the continuous inflation and expansion of the air bag B4, at the moment, the esophagus of the patient is blocked, and then the valve is closed, the air bag B4 is kept in an expansion state, and the gastric lavage operation is started. After the gastric lavage operation is finished, the valve is opened again to discharge the gas in the air bag B4, and the insertion tube 1 is taken out of the body of the patient after the air bag B4 is contracted.

It can be seen that, in the present embodiment, based on the prior art, the connecting tube in the prior art is directly changed into the air-guiding channel 5, and the air-guiding channel 5 is directly disposed in the inner wall of the insertion tube 1, so that the esophagus of the patient can be blocked by the air bag without increasing the volume of the portion of the insertion tube 1 inserted into the patient, and the insertion tube 1 is more comfortable for the patient when inserted into the patient.

Meanwhile, although the insertion tube 1 is separated into two chambers by the diaphragm arranged inside the gastric tube in the prior art, the two chambers of the gastric tube are independent, after the insertion tube 1 is inserted into the stomach of a patient, the through hole communicated with the liquid injection chamber and the liquid discharge chamber always faces to one direction, and the gastric wall around the gastric tube is required to be cleaned during gastric lavage generally, so that the gastric tube in the prior art cannot well convey cleaning liquid to the periphery of the stomach of the patient or discharge waste liquid around the stomach of the patient, and the use effect is poor. For this purpose, in this embodiment, a partition 6 is disposed inside the insertion tube 1 along the length direction thereof, the partition 6 divides the inside of the insertion tube 1 into an inlet chamber 102 and an outlet chamber 103, a gap is reserved between one end of the partition 6 close to the insertion end 101 and the inner bottom surface of the insertion end 101, and the insertion end 101 is provided with a plurality of channels 104 communicating with the inside of the insertion tube 1. Through the design, the liquid inlet cavity 102 and the liquid outlet cavity 103 are in a communicated state at the insertion end 101 of the insertion tube 1, and the insertion end 101 is provided with a plurality of channels 104, so that the cleaning liquid entering from the liquid inlet cavity 102 can be discharged from the channels 104 distributed around the insertion end 101 after reaching the insertion end 101, and the cleaning liquid can reach all parts of the to-be-cleaned position of the stomach of the patient as far as possible; on the contrary, when the liquid is drained, the waste liquid around the stomach of the patient can be drained from the liquid outlet cavity 103 as much as possible. Meanwhile, in order to make the cross sectional areas of the liquid inlet cavity 102 and the liquid outlet cavity 103 as large as possible, the normal flow of the cleaning liquid and the waste liquid is ensured. Referring to fig. 2, the side wall of the partition 6 is an arc-shaped concave surface, so that the cross-sectional areas of the liquid inlet chamber 102 and the liquid outlet chamber 103 are increased.

In addition, it is considered that, since the inlet chamber 102 and the outlet chamber 103 are communicated at the insertion end 101, large-particle impurities mixed in the waste liquid may enter the inlet chamber 102 and adhere to the inner wall of the inlet chamber 102 to contaminate the inlet chamber 102 when the liquid discharge operation is performed. For this purpose, in the present embodiment, at least one filter screen 7 is provided inside the intake chamber 102. Through setting up filter screen 7 can make large granule impurity can't get into the feed liquor chamber 102 in, guarantee that feed liquor chamber 102 does not receive the pollution. In the present embodiment, in consideration of practical cost, the filter screen 7 is provided as one, and the filter screen 7 is provided at the end of the liquid inlet chamber 102.

Also, in order to make the insertion end 101 not hurt tissues such as esophageal wall of a patient when the insertion tube 1 is inserted into the patient, the insertion end 101 is an arc-shaped structure, and meanwhile, the plurality of channels 104 are uniformly arranged on the insertion end 101, so that the cleaning solution can be more uniformly discharged from the insertion end 101.

In addition, in order to facilitate the medical staff to better control the dosage of the cleaning liquid when the cleaning liquid is added, the gastric tube of the embodiment further comprises a liquid inlet tube 8, one end of the liquid inlet tube 8 is communicated with the liquid inlet cavity 102, and the other end of the liquid inlet tube is connected with a liquid inlet container 9; the liquid inlet pipe 8 is provided with a flow controller 10. Before adding the washing liquid, add the washing liquid into liquid inlet container 9 earlier, later through opening flow controller 10 to suitable position for the washing liquid enters into feed liquor chamber 102 behind liquid inlet pipe 8, and medical personnel can be according to actual need, utilize flow controller 10 to adjust the flow size of washing liquid at any time, convenient and fast. Simultaneously in order to let medical personnel can more the addition of precision control washing liquid, foretell feed liquor container 9 is transparent container, and the outer wall of feed liquor container 9 is equipped with the scale mark. Therefore, when the cleaning liquid is added, the medical staff can control the amount of the added cleaning liquid in real time only by referring to the scale marks.

On the other hand, this embodiment still provides a gastric lavage device for gastroenterology, this gastric lavage device on the basis of current gastric lavage device, with the stomach tube that it used change into the above-mentioned gastroenterology stomach tube to make the gastric lavage operation more smooth and easy, patient's sensation is also more comfortable.

The above is only a preferred embodiment of the present invention, and is not intended to limit the present invention, and various modifications and changes will occur to those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
