Description

Technical Field

[0001] The utility model relates to the field of three-way devices, in particular to a three-way device used for severe bronchoscopic examination. Background Art

[0002] A bronchoscope is a medical device that is inserted into the patient's lower respiratory tract through the mouth or nose and is used for observation, biopsy sampling, bacteriological and cytological examinations of lobes, segments and subsegmental bronchial lesions. It can also be used for photography, teaching and dynamic recording in conjunction with a TV system. The connected biopsy sampling accessories can assist in the discovery of early lesions and are suitable for bronchial and lung disease research and postoperative examinations. A three-way device is required for bronchoscopic examinations. The three-way device is a commonly used connection tool in the medical field for delivery channels, mainly for the delivery of liquids. There are many types of medical tees and they are widely used. Disposable plastic tees are the most commonly used type in medical treatment. Disposable plastic tees are composed of a main part made of plastic material and three valve switch parts made of rubber material.

[0003] Most of the existing connection methods of three-way devices are to screw the pipe to be connected into the thread on the three-way device, which makes it very inconvenient to rotate the pipe. In addition, the connection ports of most existing medical three-way devices are fixed and cannot be bent or rotated. Therefore, when connecting multiple pipes to the tee, a long connection body will be formed, which takes up most of the space.

[0004] Therefore, those skilled in the art provide a three-way device for use in severe bronchoscopy to solve the problems raised in the above background technology. Utility Model Content

The pipes to be connected are placed in the three limiting tubes of the three-way device, and the threads on the pipes to be connected are engaged with the threads in the fixing block. The pipes to be connected can be fixed by rotating the fixing block. If the connected pipes need to be disassembled, the connected pipes can be removed by simply rotating the fixing block, thereby reducing the workload of the staff and improving the work efficiency of the staff.
