Problems solved by technology

[0003] In the prior art, the method for measuring the airway diameter as a whole is complicated, and the airway test process is not easy to operate. Because the path of the airway is irregular, it is difficult to control the direction of the existing testing device, and the Increased the difficulty of the test

Embodiment 1

[0039] Such as Figure 1 to Figure 5 As shown, a device for measuring the diameter of the airway of a human body comprises a first delivery outer tube 1, a second delivery outer tube 20, a moving inner tube 2, a display 18 and an annular bag portion 3, the moving inner tube 2 One end slides into the first delivery outer tube 1 from the tail end of the first delivery outer tube 1, and a cavity is formed between the inner wall of the first delivery outer tube 1 and the outer wall of the moving inner tube 2 ;

[0040] An optical fiber is provided in the cavity, and one end of the optical fiber is connected to the camera 17 arranged on the side wall of the first end of the second delivery outer tube 20, and the other end of the optical fiber extends out of the first delivery outer tube The side wall of 1 is connected with the display 18;

[0041] The head end of the second delivery outer tube 20 is used to be inserted into the airway of the human body, one end of the annular sac...

Embodiment 2

[0051] The difference from Embodiment 1 is that a device for measuring the airway diameter of a human body is used together with a flexible bronchoscope.

[0052] The specific implementation method is to cooperate with the OlympusBF-3c30 type bronchoscope with an outer diameter of 3.5mm and a biopsy hole, use the bronchoscope to first extend into the airway of the human body, and then extend the delivery outer tube 1 into the biopsy hole After the annular sac 3 between the first delivery outer tube 1 and the second delivery outer tube 20 protrudes from the biopsy hole at the other end, repeat the operation of the above-mentioned embodiment 1 to better measure the human airway diameter. This facilitates the positioning of the annular capsule portion 3 to an accurate measurement position.

Abstract

The invention belongs to the field of medical equipment for the pneumology department and particularly relates to a device for measuring the diameter of a human airway. One end of a moving inner tubeglidingly extends into a first conveying outer tube from the tail end of the first conveying outer tube, and a cavity is formed between the inner wall of the first conveying outer tube and the outer wall of the moving inner tube; optical fiber is arranged in the cavity and connected with a display; one end of an annular bag part is communicated with the tail end of a second conveying outer tube, the other end of the annular bag part is communicated with the head end of the first conveying outer tube, and the side wall of the moving inner tube is connected with the inner wall of the annular bagpart through an expansion device; a deviator for controlling the direction of the conveying outer tube is also arranged on the side wall of the first conveying outer tube; scales are arranged on theside wall of the part, extending out of the conveying outer tube, of the moving inner tube. The device can control the direction freely and is simple to operate and high in accuracy, and the measurement problem of the diameter of the human airway at present is solved.

Description

technical field [0001] The invention belongs to the field of respiratory medical instruments, in particular to a device for measuring the diameter of the airway of a human body. Background technique [0002] Respiratory diseases are common diseases in human body. Among them, the incidence of airway narrowing diseases caused by tumors and tuberculosis is relatively high. When the lesion causes obvious airway stenosis, patients often have dyspnea. At this time, accurate assessment of the degree of airway stenosis is crucial for clinicians to choose appropriate treatment methods. Stent implantation is widely used in the treatment of airway stenosis, and has a significant effect on relieving dyspnea caused by airway stenosis. Whether it is a metal stent or a silicone stent, it is necessary to measure the diameter of the narrow airway before placing it in order to determine the appropriate stent type. [0003] In the prior art, the method for measuring the airway diameter as a...
