Preferably, the connection tube 100 is made of transparent silicone. The silica gel material is safe and nontoxic, and material cost is low, can see the big or small degree of sealing the pipe through the connecting pipe 100 that transparent silica gel made simultaneously, is favorable to patient's smooth tube drawing. In the present embodiment, the length of the connection pipe 100 is 2 to 3 cm.

Referring to fig. 2 and 3 together, in particular, the outer balloon 200 has an outer diameter equal to the inner diameter of the endotracheal tube after inflation. The outer balloon 200 has the same inflation outer diameter as the inner diameter of the endotracheal tube, so that the outer balloon 200 can be tightly attached to the inner wall of the endotracheal tube, and external gas is prevented from entering the endotracheal tube. Before the outer airbag 200 is inflated, the outer airbag 200 is in a contracted state, which does not affect the whole tube sealing device to be placed in the tracheal catheter, and the outer airbag 200 is inflated to be filled between the outer side surface of the connecting tube 100 and the inner wall of the tracheal catheter, so that the tube sealing device is fixed in the tracheal catheter and prevents the air circulation between the interior of the tracheal catheter and the outside. Further, an outer balloon catheter 210 is connected to the outer balloon 200, and the outer balloon catheter 210 is used for connection to an inflator. The inflation device inflates or deflates the outer bladder 200 through the outer bladder tube 210. The inflation device may be a syringe that is used to inflate or deflate the outer bladder 200. Of course, the inflation device may be an air bag inflation ball, which is repeatedly pressed to inflate the outer air bag 200 through the outer air bag conduit 210, and when the air needs to be deflated, the deflation valve on the air bag inflation ball may be opened to allow the air in the outer air bag 200 to flow out. Preferably, the outer bladder 200 is made of silicone.

The inner bladder 300 has a cylindrical structure, and when the inner bladder 300 is in a maximum inflated state, the diameter of the inner bladder 300 is equal to the inner diameter of the connection pipe 100. Before the inner airbag 300 is inflated, the inner airbag 300 is attached to the inner wall of one side of the connecting pipe 100, and after the inner airbag 300 is filled with gas, the outer side surface of the inner airbag 300 is in contact with the inner wall of the connecting pipe 100 and is attached in a seamless manner, so that the circulation of inside and outside air is completely prevented, the function of completely sealing the pipe is realized, and the pipe sealing in different degrees can be realized according to the amount of inflation in the inner airbag 300. Further, an inflation hole 320 is formed on a side wall of the connection tube 100, the inflation hole 320 is communicated with the inner airbag 300, an inner airbag guide tube 310 is arranged on an outer wall of the connection tube 100, the inner airbag guide tube 310 is communicated with the inflation hole 320, and an inflation device is connected to one end of the inner airbag guide tube 310, which is far away from the inflation hole 320. The inflator inflates or deflates the inner bladder 300 through the inner bladder tube 310. Specifically, the inner bladder 300 is made of silicon gel.

In this embodiment, the outer wall of the connection tube 100 is provided with a buckle 500, the buckle 500 is located at a side of the outer airbag 200 away from the endotracheal tube, and the buckle 500 is used for being buckled on the endotracheal tube. After the endotracheal tube is arranged in to connecting pipe 100, buckle 500 joint is at the opening part of endotracheal tube, prevents to seal the intraductal device of popping out or falling into endotracheal tube, further reinforces the fixed of sealing the pipe device. Preferably, the buckle 500 is made of an elastic material. The resilient catch 500 is easier to catch or remove.

Referring to fig. 4, in the present embodiment, the valve 400 is screwed to the connecting tube 100, so that the valve is easy to detach. Specifically, the flapper 400 includes a standpipe 410 and a control member 420, the control member 420 being vertically rotatably connected to the standpipe 410 and having one end extending into an interior cavity of the standpipe 410. The control member 420 includes an external connecting rod 421 and a control ball 422 inside the standpipe 410, the connecting rod 421 passing through the sidewall of the standpipe 410 to connect with the control ball 422, the diameter of the control ball 422 being equal to the diameter of the standpipe 410. The control ball 422 is provided with a through hole 430, and the through hole 430 is communicated with the inner cavity of the vertical tube 410. When the control member 420 is rotated, the size of the through hole 430 of the control member 420 communicating with the inner cavity of the vertical tube 410 also varies, when the axis of the through hole 430 is parallel to the axis of the vertical tube 410, the communication area of the through hole 430 with the inner cavity of the vertical tube 410 is the largest, and when the axis of the through hole 430 is perpendicular to the axis of the vertical tube 410, the inner cavity of the vertical tube 410 is blocked. Preferably, the vertical tube 410 is made of transparent silicone, and when the control member 420 is rotated, the size of the through hole 430 communicating with the inner cavity of the vertical tube 410 can be clearly seen.

The basic principle of the utility model is as follows: before the patient needs to perform the trial tracheal tube drawing stage, the control member 420 on the flap 400 is rotated to communicate the through hole 430 with the vertical tube 410 and further with the breathing machine. Then, the end of the connecting pipe 100, which is provided with the outer airbag 200, is inserted into the tracheal catheter, and then the buckle 500 is clamped at the opening end of the tracheal catheter, so that the whole sealing device is prevented from falling into the tracheal catheter, and then the outer airbag 200 is inflated by using the inflating device, so that the outer side surface of the outer airbag 200 is seamlessly attached to the inner wall of the tracheal catheter, and the external gas is prevented from entering. The control member 420 is then rotated so that the through hole 430 communicates with one half of the standpipe 410, and the patient's breathing is observed. If the patient has difficulty breathing, the control member 420 is rotated to return to a state where the through hole 430 is completely communicated with the vertical tube 410, thereby determining that the patient cannot perform the tube sealing operation of the endotracheal tube at this time; if the patient breathes normally, the tube sealing stage of the tracheal tube is proved to be possible.

The control member 420 is rotated to completely communicate the through hole 430 with the vertical tube 410, and finally, the amount of inflation of the inner bladder 300 is controlled, and the degree of inflation of the inner bladder 300 can be seen through the transparent connection tube 100. The pipe sealing operation is performed to various degrees from the zero inflation amount of the inner bladder 300 to the full inflation amount of the gas. In the operation of trying to seal the tube, after the tube is sealed to each degree, the patient has difficulty breathing, and the deflation valve of the inflation device should be opened immediately to deflate the inner bladder 300, so as to relieve the pain of the patient.

The utility model has the advantages that: this endotracheal tube's seal pipe device is through aerifing to adjust the tube sealing degree for interior gasbag 300, the improvement patient of ability bigger degree seals the security of pipe in-process, the fixity of sealing the pipe device has been stabilized in setting up of outer gasbag 200 and buckle 500, valve 400 set up can inspect whether the patient can be tracheal tube's shutoff operation, transparent connecting pipe 100 is favorable to observing patient's tube sealing degree, extensively be adapted to the trachea and open patient examination tube drawing stage, safe practical use is in trachea and opens patient examination tube drawing stage, small, low in manufacturing cost.
