The utility model belongs to the field of
medical instruments, particularly relates to a splash-proof
sputum collecting device for
tracheotomy, and aims to solve the problems that when a patient coughs in the prior art,
sputum can be sprayed out along a trachea cannula, so that the environment is polluted, and the on-site environmental
sanitation is influenced. One side of the shell is fixedly connected with a gas
guide tube used for being connected with a trachea cannula, the gas
guide tube is located in the shell, the side, away from the gas
guide tube, of the shell is in an arc shape and attached to the neck of a patient, a plurality of through communicating holes are formed in the top of the gas guide tube and used for ventilation, and the bottom of the gas guide tube is fixedly connected with a drainage tube. According to the
sputum collecting device, when a patient coughs severely, the sputum enters the air guide
pipe and then enters the collecting box along the drainage
pipe to be collected, the environment is kept clean and sanitary, meanwhile, the sputum collecting device can be connected with an atomizer or an
oxygen therapy device through the connecting
pipe, and therefore the sputum collecting device is convenient to use. And the use flexibility of the device is improved.
