4 results about "Human airway" patented technology

A simulated airway for training and practicing medical procedures has an upper jaw having simulated teeth, a nasal passage, a tongue, an epiglottis, a larynx, a trachea, an esophagus, and vocal cords. Portions of the airway are reinforced with fabric. A method of making a human airway model for simulation of medical procedures includes sculpting a core for a mold from a resin material, depositing a layer of clay on the core, and placing the core in a mold. The layer of clay is removed and a polymer is injected into the mold.

The invention discloses an airway basal cell-N-acetylcysteine conjugate, which is prepared by the following steps: adding DMPE-PEG-maleimide and N-acetylcysteine into a solution, incubating at room temperature, and centrifuging, so as to obtain a DMPE-PEG-maleimide-N-acetylcysteine compound; and adding the DMPE-PEG-maleimde-N-acetylcysteine compound into a cell suspension of human airway basal cells, and incubating at room temperature to obtain the human airway basal cell suspension. According to the invention, DMPE-PEG-maleimide is used as a non-invasive carrier, and airway basal cells and a drug-N-acetylcysteine are coupled; during treatment, inflammatory response can be controlled while lung injury is effectively repaired, cells can play a homing role, and the medicine is carried to reside at the injured part for long-acting treatment. The research of the invention is of great significance to the treatment of pneumonia.

The present disclosure relates to the technical field of endoscopy, and provides a path planning method. In the method, a cross-sectional image of a target object and hardware parameters of a bronchoscope robot corresponding to the target object are obtained; according to the cross-sectional image of the target object, lesion feature information, trachea feature information and blood vessel feature information of the target object are determined; according to the hardware parameters of the bronchoscope robot, and the lesion feature information, the trachea feature information and the blood vessel feature information of the target object, an airway wall puncture biopsy path of the bronchoscope robot is determined. In this way, since multiple constraint conditions are considered in the generation process of the airway wall puncture biopsy path, the most efficient and safe airway wall puncture biopsy path can be obtained, thereby the problems of subjectivity and human error that occur when a scheme is artificially formulated can be avoided, and thus the airway wall puncture biopsy path obtained by the embodiment is more accurate and has more reference value, and the safety and efficiency of the puncture biopsy are also improved.
