气管切开术后非机械通气患者专用防喷溅蓄痰功能人工鼻的设计与应用
Design and application of a heat-and-moisture exchanger with anti-splash sputum-reservoir functions for tracheotomised patients with non-mechanical ventilation
摘要
Abstract
After tracheostomy,the airway of patients with non-mechanical ventilation is directly exposed to the external environment.This exposure can lead to airway dehydration,mucosal dryness,and sputum desiccation,thereby increasing the risk of pulmonary infection and atelectasis.Additionally,it can cause secretion splatter and the risk of pathogen transmission.The heat and moisture exchanger serves not only to provide heat and humidity but also to seal the circuit.However,the heat and moisture exchanger has its drawbacks.During coughing,sputum can be expelled into the inner surface of the heat and moisture exchanger,and due to gravity,it may fall back into the patient's respiratory tract,causing irritation and potentially worsening lung infection.Sputum adhering to the heat and moisture exchanger can also increase airway resistance and may even cause complete occlusion.Consequently,medical staff of the Tongxiang First People's Hospital designed a novel heat and moisture exchanger equipped with anti-sputum splash and sputum storage capabilities for patients with non-mechanical ventilation post-tracheostomy.This design has been awarded the National Utility Model Patent of China(Patent No.:ZL 2021 2 0672381.3).The patent comprises two components:a novel anti-splash heat and moisture exchanger and an integrated sputum-collection cartridge.This device preserves the heat and moisture exchanger's heat-and-moisture exchange and microbial-barrier functions while preventing sputum-related obstruction,facilitating passive drainage of secretions and minimising pathogen exposure for healthcare workers and the surrounding environment.关键词
