Respiratory medicine nursing drug dosing device

Abstract

The invention relates to the technical field of medical instruments, in particular to a respiratory medicine nursing drug dosing device comprising an injection mechanism, an occlusion disc and a guiding tube. One end of the guiding tube is connected and communicated with the injection mechanism, and the other end of the guiding tube penetrates a through hole formed in the occlusion disc for a patient to occlude. One end of the guiding tube away from the injection mechanism is provided with a first air bag and a second air bag. The first air bag and the second air bag are both communicated withan air guiding chamber disposed outside the guiding tube in the sleeve mode. The air guiding chamber is communicated with an air supply mechanism through a hard tube, a drug spraying head is arrangedbetween the first air bag and the second air bag, and a plurality of drug outlet holes communicated with the inside of the guiding tube are formed in the drug spraying head. The dosing device is novel in design, can inflate the first air bag and the second air bag through the air supply mechanism to enable the first air bag and the second air bag to expand to be attached to the respiratory tractto prevent the guiding tube from damaging the respiratory tract.

Problems solved by technology

[0004] The Department of Respiratory Medicine often needs to use drug delivery devices to administer medicine to the respiratory tract. When taking medicine, the drug guide tube needs to be inserted into the patient's respiratory tract. However, the existing drug guide tube is a simple pipeline, which is easy to cause damage to the patient's respiratory tract during insertion.
