A kind of oesophagoscope cuff
Technical field
The invention belongs to Medical Devices, more particularly to a kind of oesophagoscope cuff.
Background technology
Eaten through transesophageal ultrasound probe to implement the necessary equipment of transesophageal echocardiography inspection, it is necessary to be inserted through pars oralis pharyngis
Pipe realizes ultrasound cross-section.
At present bulky through transesophageal ultrasound probe, easily cause in implantation process of popping one's head in patient discomfort and
The damage (pharyngeal bleeding, pain or esophageal injury even esophageal perforation) of oropharynx oesophagus.Although have small-sized through esophagus ultrasound
Probe can carry out the imaging of echocardiogram, but small-bore ultrasonic probe enters in oesophagus, due to can not be pasted with esophageal wall
Close closely, certain space between probe and esophageal wall be present, good sound transmitting window can not be formed, therefore small-bore oesophagus surpasses
Sonic probe usually has phenomena such as image quality difference.Due to good local anaesthesia can not be carried out, it is clear-headed insert probe during
Usually there is sense of discomfort, limit the application of this technology, therefore the injection pipe of local anaesthetics need to be increased.
