The invention discloses a novel damp-heat exchange sounder. The novel damp-heat exchange sounder comprises a damp-heat exchange cabin and an orificium fistulae shield; the orificium fistulae shield comprises a silica gel hose and a metal support fixed at the top of the silica gel hose; the damp-heat exchange cabin comprises a cabin body and a screw cap in threaded connection with the cabin body; ablocking fence is further arranged at the bottom of the damp-heat exchange cabin; two air outlet holes are formed in the upper end face of the screw cap; a vent valve and a communicating vessel are arranged in the air outlet holes respectively; the vent valve and the communicating vessel communicate with a cavity; and the communicating vessel is connected with a sounding reed. The novel damp-heatexchange sounder can protect the airway state of a patient subjected to total laryngectomy, and damage to trachea and lung by severe environment is avoided; and meanwhile, a sounder assembly is addedto improve the sounding requirement of the patient.
Description
technical field [0001] The invention relates to the technical field of medical devices, in particular to a novel heat and humidity exchange sounder. Background technique [0002] At present, there are many kinds of heat and humidity exchangers, but they are mainly used for airway protection of patients with tracheotomy. For patients after total laryngectomy, there is a lack of related technologies and products that can not only assist pronunciation but also exchange heat and humidity. Contents of the invention [0003] In view of the above-mentioned technical deficiencies, the purpose of the present invention is to provide a new type of humid heat exchange sounder, which can protect the airway state of patients with total laryngectomy and avoid damage to the trachea and lungs in harsh environments; at the same time, add sounder components to improve the patient's health. Pronunciation requirements. [0004] In order to solve the problems of the technologies described abov...
