An automatic control system for a tracheobronchial pneumatic stimulator (10) intended to be connected to a subject, the stimulator (10) comprising: a pressure unit (13) configured to generate a set of negative pressure pulses during a relaxation exhalation of the subject, each pulse corresponding to an output of the pressure unit (13); and a connection assembly (11, 12) configured to connect the pressure unit (13) to the subject's respiratory system. The control system comprises: a pressure sensor (15) configured to measure an internal negative pressure (P) applied to the subject's respiratory system corresponding to each pulse after it is generated by the pressure unit (13); a calculation module (32) configured to compare in real time the absolute value of the measured internal negative pressure (P) with a predetermined threshold (S) and, based on the comparison result, determine an updated output value to be applied to the pressure unit (13) such that the absolute value of the subsequent internal negative pressure (P) corresponding to the updated output value is less than the absolute value of the threshold (S); and a control module (33) configured to apply the updated output value to the pressure unit (13) before the generation of the next pulse.

Devices, systems, and methods for localized delivery of a chemotherapy, hormonal therapy, or targeted drug / biologic therapy to a target tissue area of an internal body organ of a patient. Computer systems may be used for planning and navigation in super selective drug delivery via a tracheobronchial airway. A catheter may be used to form a sealed treatment chamber in a natural lumen extending through the target tissue area. Air is purged from the chamber, which is then filled with a liquid drug solution for an adequate treatment session time, solution volume and drug concentration to saturate the target tissue area, thereby providing the treatment. The liquid drug solution may be circulated or recirculated through the chamber or maintained stationary therewithin to saturate the target tissue area. The chamber is evacuated at the end of the treatment session.

By pulling the pulling rope, the fixing sleeve can be dragged to drive the end of the trachea body to generate angle change, the trachea body can extend to a target position conveniently, oxygen can be connected to the outer end of the catheter subsequently, the oxygen is directly fed into the trachea and the bronchus, and low, medium and high flow ventilation is achieved.

The invention provides an application of exosomes secreted by autologous stem cell culture in bronchitis COPD treatment, based on an autologous adipose-derived stem cell (ADSCs) organ-like cell directional culture technology, stem cells are induced to be differentiated into bronchial organ-like cells, the exosomes secreted by the bronchial organ-like cells are collected, and the COPD treatment of bronchitis is realized. Through atomization administration, chronic bronchitis, acute bronchitis and chronic bronchitis can be treated. The exosome of the tissue cells of the autologous bronchial mucosa directly reaches the bronchial mucosa through aerosol inhalation, and plays a role through the following ways: anti-inflammation: inhibiting an NF-kappa B pathway, and reducing the release of IL-6 and TNF-alpha; epithelium repair: activating a Wnt / beta-catenin signal to promote basal cell proliferation and enhance a mucus cilia removal function; immunoregulation: regulating and controlling polarization of macrophages to M2 anti-inflammatory phenotype. Therefore, local concentration is high, whole-body side effects are avoided, the whole path of trachea-bronchus-alveolus alveolus is covered, and precise targeted repair is achieved.
