Description

Handle type lavage device and fiber bronchoscope adopting same

Technical Field

The invention belongs to the technical field of medical instruments, and particularly relates to a handle type lavage device and a fiberoptic bronchoscope using the same.

Background

Fiberbronchoscopy is an endoscopic technique, which can directly see the respiratory airway condition of a human body, determine the diseased part and the performance, and simultaneously can lavage, aspirate sputum, stop bleeding and the like on the bronchus under direct vision.

In the current clinic, a critically ill patient suffers from cough, expectoration and weakness due to long-term bed rest, or insufficient airway humidification due to long-term use of a respirator, so that a large amount of sputum is generated to block a bronchus, and a common sputum suction method is limited by the length of a sputum suction tube, so that a sputum suction part is mostly positioned above a bronchus carina and cannot reach the bronchus, so that the sputum in the deep part of the bronchus cannot be sucked out or cannot be sucked out thoroughly, and the lung infection of the patient is caused; moreover, the incorrect sputum suction method of nurses can cause erosion and bleeding of tracheal mucosa, and in severe cases, perforation of trachea can be caused.

In order to solve the above problems, it is common practice to use a fiber bronchoscope for performing lavage, sputum aspiration and local drug delivery. During operation, a doctor needs to hold the handle of the fiberoptic bronchoscope with one hand and hold the catheter at the tail end of the fiberoptic bronchoscope with the other hand to insert the catheter into a patient. In the operation process, both hands of the doctor are occupied, and other operations cannot be performed. Therefore, when needing to utilize bronchoscope to carry out the lavage, the doctor sees the thick, the dry or position that needs local hemostasis of sputum through the fiber bronchoscope, then needs the assistant to aspirate and irritate after the lavage liquid through the syringe.

In the above operation process, the physician and the assistant are required to cooperate with each other. Therefore, in actual operation, not only a large amount of human resources are occupied, but also whether the lavage timing and lavage quantity can be accurately grasped needs to depend on the tacit degree between the doctor and the assistant, so that a great potential safety hazard exists in the whole treatment process.
