Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, in particular to a fiber bronchoscope lavage device. Background Technique

[0002] A fiber bronchoscope (abbreviated as fibrobronchoscope) is an instrument used to diagnose bronchial diseases by using a light guide beam composed of tens of thousands of very thin fibers made of highly light-transmitting glass or propylene resin. Its lumen is very small, flexible and bendable, with strong light-conducting ability, high brightness and clear vision. It can easily enter the trachea from the oral cavity or nasal cavity until the orifices of each bronchial segment. Doctors can directly observe the trachea, the openings of the left and right main bronchi and the mucosal conditions. They can also gently brush the suspicious mucosa several times with a very small brush. The brush specimens can be used for smear staining and culture examination; or a certain amount of sterilized purified water can be injected to wash the diseased part in the bronchus and then aspirated for smear and culture examination. If there is a granulomatous lesion that needs to be differentiated from lung cancer, biopsy pathological examination can be performed.

[0003] At present, when the existing fiber bronchoscope is lavaged, usually a syringe filled with sterilized purified water is used to inject the sterilized purified water into the diseased part in the bronchus through the biopsy channel port inside the fiber bronchoscope. After lavaging the diseased part in the bronchus, the lavage fluid is then aspirated. The operation is very inconvenient. If repeated lavage is required, it will consume a lot of time of medical staff.

[0021] By sleeving the first port of the three-way valve 11 with the biopsy channel port 13, the second port with the liquid suction tube 23, and removing the negative pressure aspirator originally sleeved on the surface of the suction tube interface 12 and sleeving it with the negative pressure connector 25, then connecting a syringe filled with sterilized purified water to the third port and injecting it into the fiber bronchoscope body 1 through the biopsy channel port 13. During the process, adjust the valve on the surface of the three-way valve 11 to close the channel between the biopsy channel port 13 and the second port. After the sterilized purified water is injected into the fiber bronchoscope body 1 and into the bronchial lesion site of the patient, continue to adjust the valve on the surface of the three-way valve 11 to close the channel between the biopsy channel port 13 and the third port, and open the channel between the biopsy channel port 13 and the second port, so that the suction tube 24 with negative pressure extracts the air inside the bottle body 21, and then the sterilized purified water used to lavage the inside of the fiber bronchoscope body 1 is inhaled into the bottle body 21 through the liquid suction tube 23. Thus, when lavaging the fiber bronchoscope body 1, the syringe and the liquid suction tube 23 do not need to repeatedly establish a connection relationship with the biopsy channel port 13, greatly improving the lavage efficiency, reducing the operation steps of medical staff, and being more convenient to use.
