Abstract
Provided is a new ventilator that can be used for pulmonary resuscitation without requiring an electrical driving source. A ventilator includes a housing. The housing has an input port through which a gas is introduced into the housing, a main port through which the gas that is to be sent to and inhaled by a patient and a gas that is exhaled by the patient pass, an exhaust port through which the gas inhaled or the gas exhaled is exhausted from the housing, a ventilation path connecting the input port and the main port to each other, and a relief valve that is opened by receiving a pressure from the ventilation path and that allows communication between the ventilation path and the exhaust port so as to release the pressure.
Claims22
A ventilator comprising:
- a housing,
- wherein the housing has
- an outer peripheral wall,
- a lid, the lid and the outer peripheral wall cooperatively defining the housing,
- an input port, formed on the outer peripheral wall, through which a gas is introduced into the housing,
- a main port, formed on a bottom surface of the housing, through which the gas that is to be sent to and inhaled by a patient and a gas that is exhaled by the patient pass,
- an exhaust port, formed on the outer peripheral wall, through which the gas to be inhaled or the gas exhaled is exhausted from the housing,
- a heat and moisture exchanger filter disposed inside the housing and between the main port and the exhaust port,
- a ventilation path connecting the input port and the main port to each other, and
- a relief valve, formed inside the housing, that includes a valve body configured to be opened by receiving a pressure from the ventilation path and that allows communication between the ventilation path and the exhaust port in such a manner as to release the pressure.
A ventilator comprising:

- a main port through which the gas that is to be sent to and inhaled by a patient and a gas that is exhaled by the patient pass,
- an exhaust port through which the gas inhaled or the gas exhaled is exhausted from the housing,
- a ventilation path connecting the input port and the main port to each other, and
- a relief valve that includes a valve body configured to be opened by receiving a pressure from the ventilation path and that allows communication between the ventilation path and the exhaust port in such a manner as to release the pressure,
- wherein the relief valve further includes
- a pressure setting dial that has a disc-like shape and that is configured to be rotated to enable setting of the pressure at which the valve body is opened, and
- a dial cover holding the pressure setting dial such that the pressure setting dial is rotatable,
- wherein the dial cover includes a contact receiving portion that stops rotation of the pressure setting dial by coming into contact with the pressure setting dial, and
- wherein the pressure setting dial includes a stopper that comes into contact with the contact receiving portion at a position at which an intermediate set pressure between a minimum set pressure and a maximum set pressure is set.
