Summary: | The present invention provides a small-size, small-weight, low-cost artificial respiration apparatus which can easily be used in an ordinary hospital.The artificial respiration apparatus 10 includes: a positive blower 12p for generating a positive air pressure Ap; a negative blower 12n for generating a negative air pressure An; a rotary valve mechanism 54 for alternately selecting the positive pressure Ap generated by the positive blower 12p and the negative pressure An generated by the negative blower 12n and converting them into an oscillating air pressure Apn; and a diaphragm block 56 urged by the oscillating air pressure Apn from the rotary valve mechanism 54 to operate to supply air to a patient P. Use of the positive blower 12p and the negative blower 12n significantly reduces the load, enabling to use ones available on market, i.e., small-size, small-weight, low-consumption blowers. |
