Detailed implementation mode

[0020] Next, the technical solutions in the embodiments of the present application will be described in conjunction with the accompanying drawings in the embodiments of the present application.

[0021] It should be noted that: similar reference numerals and letters denote similar items in the following drawings. Therefore, once an item is defined in one drawing, it does not need to be further defined and explained in subsequent drawings. At the same time, in the description of the present application, the terms "first", "second", etc. are only used for distinguishing descriptions and cannot be understood as indicating or implying relative importance.

[0022] The embodiment of the present application provides a tracheal catheter. The tracheal catheter is inserted into the trachea of the human body, and the ultrasonic imaging probe 2 is inserted into the tracheal catheter to detect the lesion and improve the imaging quality.

[0023] As Figure 2 shown, the tracheal catheter includes a tube body 1. The ultrasonic imaging probe 2 can be inserted into the tube body 1. The tube body 1 is inserted into the trachea. A capsule membrane 3 is attached to the outer surface of the tube body 1. Both ends of the capsule membrane 3 are fixedly connected to the tube body 1 at the middle positions at both ends of the capsule membrane 3, so that the capsule membrane 3 and the tube body 1 form two separated capsule cavities. The purpose of separating the two capsule cavities is to reduce the mutual influence between the two capsule cavities when they expand. One of the capsule cavities is configured as the first capsule cavity 31, and the first capsule cavity 31 is used to fill with a contrast agent. The contrast agent causes the first capsule cavity 31 to expand and contact the trachea. In this way, when the ultrasonic imaging probe 2 extends to the position of the first capsule cavity 31, since the contrast agent makes the first capsule cavity 31 contact the trachea, the air between the ultrasonic imaging probe 2 and the trachea is reduced, improving the imaging effect of the ultrasonic imaging probe 2; the other capsule cavity is the second capsule cavity 32. A fluid is introduced into the second capsule cavity 32 to cause the second capsule cavity 32 to expand and contact the trachea, and the tracheal catheter is then positioned in the trachea, improving the stability of the tracheal catheter and the human trachea, facilitating the imaging of the ultrasonic imaging probe 2, and improving the imaging effect.

[0024] In addition, by providing a capsule membrane 3 fixedly connected to the tube body 1 to form two capsule cavities in the embodiment of the present application, the manufacturing cost of the tracheal catheter can be reduced.

[0025] Optionally, the first cavity 31 may be the cavity at the end away from the medical staff. Of course, in some cases, it may also be the cavity at the end close to the medical staff. As a preferred embodiment, in the embodiments of the present application, the cavity at the end away from the medical staff is used as the first cavity 31, which is convenient for the ultrasonic imaging probe 2 to detect the lesion.

[0026] In addition, the ultrasonic imaging probe 2 can select an annular array ultrasonic probe to generate ultrasonic waves, so as to realize the circumferential real-time scanning of the ultrasonic imaging probe 2.

[0027] Optionally, since the tube body 1 has an elastic force, the diameter of the tube body 1 can be designed to be adapted to the diameter of the ultrasonic imaging probe 2, so as to reduce the gap between the ultrasonic imaging probe 2 and the tube body 1 and improve the imaging quality. At the same time, during the detection process, some coupling agents can also be applied on the ultrasonic imaging probe 2 to reduce the air between the ultrasonic imaging probe 2 and the tube body 1.

[0028] Optionally, when the tube body 1 is inserted into the trachea, a small amount of developing liquid can be introduced into the first cavity 31. In this way, when the tube body 1 moves in the trachea, the medical staff can determine the position of the first cavity 31 in real time, so that the first cavity 31 can be aligned with the lesion position, and thus the ultrasonic imaging probe 2 can also be aligned with the lesion position, facilitating the acquisition of the image of the lesion.

[0029] Optionally, a developing member can also be arranged around the first cavity 31 to determine the position of the first cavity 31 in the trachea, facilitating the alignment of the first cavity 31 with the lesion position.

[0030] Optionally, the fluid can be gas or liquid.

[0031] Optionally, the connection mode between the membrane 3 and the tube body 1 is a hot-melt integration mode, that is, the two end edges of the membrane 3 are integrally connected to the tube body 1 by hot melting, and the middle regions of the two ends are also integrally connected to the tube body 1 by hot melting. After the first cavity 31 and the second cavity 32 expand, an annular cavity surrounding the outer wall of the tube body 1 is formed, and the outer surface contacts the trachea.

By providing the first opening 11 on the tube body 1, one end of the first connecting tube 4 communicates with the first opening 11, and the developer is introduced into the first connecting tube 4, so that the developer enters the first bladder cavity 31, causing the first bladder cavity 31 to expand, reducing the gap between the first bladder cavity 31 and the trachea, and facilitating imaging.
