[0038] The inner diameter of the second fixed plate 7.1 corresponds to the surface abutting the pipe body, and the outer diameter of the movable plate 8.1 corresponds to the surface facing the pipe body 1.

The first connecting hole is spirally screwed with a first cover, and the first cover has the first sealing film; the second connecting hole is spirally screwed with a second cover, and the second cover has the second sealing film. The cutter piston is fixed with a sliding block 8.6, and the sliding block 8.6 has a containing groove, and the containing groove is connected with a limiting protruding block 8.7 through a third spring.

The first connecting pipe 2.1.1 and the second connecting pipe 2.2.1 are flexible pipes, and the third connecting pipe 14 is a rigid pipe.

[0039] As shown, the first space can be used for drainage, and the liquid in the stomach and intestines that needs to be drained can be drained by negative pressure. At this time, the first supporting air bag can be inflated by using the first air pumping unit, and the second supporting air bag can be deflated by using the second air pumping unit, so that the first space is expanded to facilitate drainage operation; when it is necessary to deliver liquid medicine or nutrient solution into the stomach and intestines, the second supporting air bag can be inflated, and the first supporting air bag can be deflated, so that the second space is expanded for liquid supply.

[0040] In addition, since the drainage tube is inserted into the stomach of the patient after all, sometimes the situation occurs, for example, the negative pressure is too large or the positive pressure is too large when the liquid is supplied, the doctor can not be the first time to perceive, but the patient can be the first time to perceive, but the ordinary drainage tube operating end is in the doctor's hand, the patient can not cope with the emergency in time. Therefore, the following structure is designed: in the initial state, the abutment column abuts the inclined surface of the first groove (because the elastic force of the pressing spring is relatively large, so it can overcome the tension of the elastic pull rope, and the end of the sliding plate abuts the closed end of the sliding plate channel); the limiting protruding block is located outside the limiting groove; the needle unit in the first piston tube is located in the first piston tube, and the needle unit in the second piston tube is located in the second piston tube; the inner tube sealing film, the first sealing film and the second sealing film are not pierced. The patient holds the fixing sleeve in the mouth, and the limiting flange can be limited, the fixing sleeve is completely slid into the mouth, the limiting convex rib can prevent the fixing sleeve from rotating, and the teeth of the patient abut the pressing block (the elastic force of the pressing spring is relatively large, and the patient can also prevent the pressing spring from being pressed by mistake), at this time the drainage tube can be used normally.

[0041] When the patient feels abnormal discomfort, the patient forcibly installs the pressing block, in the pressing process, the abutment column first slowly moves along the inclined surface, so that the sliding plate slides, so that the air pressure in the abutting air bag reaches a relatively large value, so that the abutting air bag tightly abuts the pipe body, so that the pipe body is completely fixed, avoiding the vibration, rotation and the like of the pipe body, in addition, the sliding piston needle unit pierces the first and second sealing films (the purpose of piercing is that the first and second supporting air bags are in communication with the outside, so that when the moving plate is quickly pressed down later, the first and second supporting air bags can be flattened), and the inner tube piston needle unit approaches the inner tube sealing film but has not been pierced; then when the abutment column slides out of the first groove, the elastic pull rope will quickly make the sliding plate move a large distance, so that the inner tube sealing film is pierced, and the air pressure quickly pushes the cutter to make the cutter cut off the limiting pull rope, the moving plate is quickly and powerfully flattened and closed by the pipe body under the compression of the second spring, since the abutting air bag clamps and abuts the pipe body at this time, and the fixing sleeve is also bitten in the mouth of the patient, therefore the vibration generated by the moving plate pressing down will not cause the drainage tube in the patient's body to vibrate. At this time, the abutment column abuts the plane of the second groove; the limiting protruding block is located in the limiting groove; the inner tube sealing film, the first sealing film and the second sealing film are all pierced; the moving plate and the second fixed plate clamp the pipe body and make the first space and the second space in the pipe body located between the moving plate and the second fixed plate part flattened and closed. So the doctor can do further processing, such as taking out the drainage tube.

[0042] Although the present application is illustrated and described with reference to the preferred embodiments, it is understood that various changes and modifications can be made to the present application without departing from the scope of the claims of the present application.
