The utility model relates to a melamine pulse batch-type purging separation device, the output end is connected with a pipeline system, the device comprises a branch air pipe, a flow deflector is arranged at the connecting position of the pipeline system and the branch air pipe, the flow deflector wraps the outlet of the branch air pipe and forms a flow guide cavity, the flow deflector comprises an arc-shaped part and a straight line part, and the arc-shaped part is connected with the straight line part. And the straight line part is parallel to the flow direction of gas in the pipeline system. According to the utility model, the valve is intermittently purged through the branch air pipe pulse, so that the interior of the valve body is ensured to be clean, and the valve acts freely and is closed tightly; meanwhile, the flow deflectors are arranged, the flow direction of gas can be changed, the gas is forced to be parallel to the linear part, and therefore the gas flowing out of the branch gas pipes and the gas flow direction in the pipeline system are the same, and the pulse effect of compressed gas can be reserved.

Systems and methods involve abrading a patient lung airway wall to reduce mucus production therein. Exemplary techniques include rotationally and / or linearly oscillating an abrasive material against the airway wall so as to damage mucus producing tissues, for example by removing goblet cells, while destroying less than the entire airway wall. The abrasive material may be present on the surface of an expandable balloon body or another expandable device, which can be delivered to the patient treatment site via a bronchoscope. In some cases, the abrasion techniques can cause cell damage or death at a controlled or predetermined tissue depth.

The invention relates to an airway lesion measurement system and method based on composite driving and modeling, the system can enter an airway through a bronchoscope to measure the diameter and length of a lesion site, and the system comprises a composite driving expansion module which comprises a pneumatic bag cavity and a shape memory alloy skeleton and is used for executing an expansion step; the self-locking anchoring module is integrated on the shape memory alloy framework and is used for executing a self-locking step; the three-dimensional dynamic modeling module comprises a sensor array and a data processing unit which are arranged on the shape memory alloy framework and is used for executing a modeling step; and the respiration synchronization module is used for receiving a respiration gating signal of the bronchoscope and controlling the three-dimensional dynamic modeling module to carry out data acquisition in a preset time window of end expiration. Compared with the prior art, the method has the advantages of being efficient in operation, convenient, easy to use, accurate and reliable in measurement performance, good in safety performance and the like.

This invention discloses an automated bronchoscope system for clearing airway secretions, relating to the field of automated bronchoscopy. The system includes: an endoscope image acquisition module for real-time acquisition of images of the airway lumen distal to the bronchoscope; a secretion recognition module for analyzing the airway lumen images to identify secretion targets and output their aspirability characteristics; an operation decision module for determining, based on the aspirability characteristics, whether the current secretion target is within a preset airway level where suction can be performed, and generating a suction command if the determination is positive; and a suction execution module for applying negative pressure to the secretion target through the suction channel of the bronchoscope in response to the suction command. This solution achieves precise positioning and selective suction of sputum targets within the airway, effectively avoiding the risk of aspirating airway tissue or foreign objects, and improving the success rate of clearing secretions of different characteristics.
