Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of esophageal dilatation after esophageal cancer operation, in particular to an automatic inflation dilatation balloon set for esophageal dilatation. BACKGROUND

[0002] In clinic, esophageal early cancer patients can be treated by endoscopic submucosal dissection. In the past, patients with esophageal full mucosa and most mucosa were not placed with a balloon, and postoperative esophageal stenosis occurred, which required intermittent endoscopic esophageal dilatation. At present, medical staff will place a self-control dilatation balloon in the patient, and the patient will take it home after discharge, use a syringe and a tee joint, inflate once every 1.5 hours, dilate the balloon to support the esophagus, and each dilatation time is 10 minutes (which can be adjusted according to the doctor's experience), and then use the syringe to extract the gas after dilatation. The wearing time is about 2 months, which can reduce the occurrence of postoperative esophageal stenosis. However, in actual use, patients or their families have difficulty in performing intermittent inflation and deflation operations, especially at night.

[0003] Therefore, according to clinical experience, an automatic inflation dilatation balloon capable of automatic inflation and deflation is designed. On the basis of the traditional dilatation balloon, a gas pump capable of automatic inflation and deflation is added to realize the timed deflation and inflation of the dilatation balloon, solve the problem that the patient cannot operate himself, and there is no need for repeated operation at night, which guarantees the rest time of the patient and is more humanized in design. At the same time, the function of manual inflation and deflation through the syringe is also retained, which can be used flexibly according to the needs, so that the patient can easily realize the inflation and deflation of the balloon, and the practicality is strong.

DETAILED DESCRIPTION

[0018] Clearly, the described embodiments are merely a part of the embodiments of the present application, but not all the embodiments. Based on the embodiments of the present application, all the other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application. Embodiment 1

[0020] The charging and pumping assembly is used for realizing automatic inflation and pumping of the dilation balloon 2, specifically, a four-way pipe 3 is connected to the end of the catheter 1, the charging and pumping assembly comprises a charging and pumping pump 5, the charging and pumping pump 5 is provided with an inflation end 6 and a pumping end 10, the inflation end 6 and the pumping end 10 are respectively connected with an inflation three-way pipe 7 and a pumping three-way pipe 11, the inflation three-way pipe 7 is provided with an inflation port 8 and an exhaust port 9, the pumping three-way pipe 11 is provided with a pumping port 12 and an air inlet 13, the inflation port 8 and the pumping port 12 are connected with the four-way pipe 3, the inflation port 8, the exhaust port 9, the pumping port 12 and the air inlet 13 are all provided with electromagnetic valves 14, as a conventional design familiar to those skilled in the art, the charging and pumping assembly should also comprise a controller, the controller is electrically connected with the charging and pumping pump 5 and the electromagnetic valves 14.

[0021] In addition, the three-way pipe 3 is also connected with the manual valve 4, a syringe 15 is inserted into the manual valve 4, so as to realize manual inflation and pumping of the dilation balloon 2.

[0022] In actual application, when the charging and pumping pump 5 is needed to be used for inflation, as shown in Figure 2 , the controller only controls the electromagnetic valves 14 on the air inlet 13 and the inflation port 8 to be in an open state, the remaining electromagnetic valves 14 and the manual valve 4 are all in a closed state, the charging and pumping pump 5 works, a certain amount of gas is injected into the catheter 1, the dilation balloon 2 is lifted up, then the electromagnetic valves 14 on the inflation port 8 and the air inlet 13 are closed, so as to avoid gas leakage;
