The invention discloses a respiratory
nursing training device for children
asthma, which relates to the technical field of
medical instruments and comprises an outer shell, an inspiration control mechanism, a
respirator, a connecting
pipe, an inner cavity, an expiration control mechanism, an expiration cavity, an expiration adjusting mechanism, a first transparent cover plate, an inspiration adjusting mechanism, a second transparent cover plate, an inspiration cavity and a filter. The
respirator has the advantages of being reasonable and simple in structure, low in production cost and convenient to install, and the
respirator is tightly connected with the connecting
pipe and the inner cavity, so that the
air tightness during use is guaranteed; the
breathing process can be accurately controlled, during inspiration, the inspiration control mechanism ensures that a child can only inhale air from the inspiration cavity, the inspiration adjusting mechanism can adjust the inspiration resistance by rotating an adjusting head and utilizing cooperation of a screw and a movable block according to actual requirements, filtered
fresh air can be supplemented after inspiration is completed, and the
breathing effect of the child is improved. The through hole in the guide hole is beneficial to adjusting the
airflow pressure of the air suction cavity, and meanwhile the counting switch can
record the number of air suction actions.
