Embodiment 1

[0039] A kind of alveolar lavage system, including waterway module, circuit control module and display module, such as figure 1 As shown, the system is placed on the trolley 7, and the alveolar lavage operation on the lung model 6 is taken as an example to describe the structure and principle of the system.

[0040] Such as figure 2 As shown, the structure of the waterway module includes a bronchoscope 1, a pump, a lavage fluid storage device, and a lavage fluid collector. The structure of bronchoscope 1 is as follows image 3 As shown, it includes an insertion part 13 , a bending part 12 , a front end part 11 , a light guide tube 51 , a light guide connection part 5 , an operation part 14 , and an eyepiece part 145 . The operation part 14 is provided with a water inlet 141 , a negative pressure suction hole 142 , a water outlet control button 143 , an adjustment knob 144 and an eyepiece part 145 , wherein the adjustment knob 144 is used to control the bending part 12 .

Embodiment 2

[0048] An alveolar lavage system includes a user interface arranged in a user interface housing. The user interface is configured to control, for example, by sending a "start," "stop," or "pause" control signal to the control system in response to the user providing user input (e.g., by pressing one or more buttons of the user interface). Operation of the irrigation system. The user interface may include a touch-sensitive surface, such as a touch screen, for receiving user input. All the other structures are the same as in Example 1.

Abstract

The invention relates to a pulmonary alveolar lavage system. The pulmonary alveolar lavage system comprises a waterway module and a circuit control module. The waterway module comprises a bronchoscope, a lavage fluid storage device and a lavage fluid collector, a lavage pump is arranged between the bronchoscope and the lavage fluid storage device, and a recovery pump is arranged between the bronchoscope and the lavage fluid collector; the circuit control module comprises a sensor and a control chip; and a stable water bag is arranged on the side wall of the front end of the bronchoscope, the sensor is arranged on the inner wall of the front end, and the control chip is connected with the sensor, the lavage pump and the recovery pump. Compared with the prior art, the phenomenon that the head of the bronchoscope deviates during lavage can be avoided, effective lavage of a target area is guaranteed, the percent of pass of follow-up recycled liquid is guaranteed, and the accuracy of recycled liquid sampling is improved; and meanwhile, the subjective participation degree of doctors can be reduced, the operation of an alveolar lavage operation is more standardized, so that adverse effects caused by lack of experience of a user are avoided, and meanwhile, the success rate of an operation is improved.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to an alveolar lavage system. Background technique [0002] Bronchoalveolar lavage technique refers to the injection of normal saline into the bronchoalveolar through a bronchoscope and suction, to collect the alveolar surface fluid (diagnostic) and to remove the material filled in the alveoli (therapeutic), to carry out inflammation and immune cells and soluble Substance inspection, to achieve the purpose of diagnosis and treatment. [0003] According to clinical medical anatomy and pathological analysis, there is viscous gelatinous mucus in the alveoli of patients with new coronary pneumonia. In addition, the massive cellular infiltration and interstitial fibrosis of the alveolar interstitium also make the normal gas O of the alveolar wall 2 , CO 2 The exchange function is rationally shielded and disabled, and hypoxia will damage cells, tissues and organs, so for patien...
