초록 ▼

A respirator is described using pneumatic elements to generate a variety of operating modes. A gas mixture is passed through a patient connection which is coupled to supply the gas through a patient port to a patient. After passing the patient port the gas is controllably exhausted to atmosphere through an exhaust port in a control valve. The control valve regulates the closure of the exhaust port to provide inspiration and expiration control at the patient port. Pneumatic logic elements are combined to provide automatic inspiration and expiration support with different modes such as volume limited or pressure limited and with selection over the duration of the respective breathing phases. Various operating modes are obtained with variable restrictors selectively placed with the pneumatic logic elements.

대표청구항 ▼

A compact respirator operating in an ambient environment comprising patient connection means having a patient port, an inlet port and a control port coupled in communication with the patient port for delivering breathable gas; means for supplying the inlet port with a flow of breathable gas at a rate selected to aid the breathing cycle of a patient breathing gas from the patient port, said gas being continuously suppliable through the inlet port to the patient port and to the control port; a control valve coupled between the control port and the ambient environment to controllably release gas from the control port for a corresponding control of gas at the patient port; means including a pneumatically controlled bistable gas pressure controlling element operatively coupled to the control valve to control inspiratory gas flow to the patient port during one state of the bistable element and enable expiratory gas flow away from the patient port during the other state of the bistable element; and pneumatic oscillating means for providing cyclic gas pressures between levels selected to actuate the bistable gas pressure controlling element between its states, a first gas pressure level from the pneumatic oscillating means being selected to endure in correspondence with a desired length of time of inspiratory gas flow to the patient port and a second gas pressure level from the pneumatic oscillating means being selected to endure in correspondence with a desired length of time of the expiratory gas flow away from the patient port; whereby the patient port may be provided with a continuous supply of breathable gas from the inlet port independent of the state of the control valve while producing inspiration and expiration respiratory support.
