摘要： Medical techniques include systems and methods for administering a positive pressure ventilation, a positive end expiratory pressure, and a vacuum to a person. Approaches also include treating a person with an intrathoracic pressure regulator so as to modulate or upregulate the autonomic system of the person, and treating a person with a combination of an intrathoracic pressure regulation treatment and an intra-aortic balloon pump treatment.

摘要： Described herein is a respiratory care apparatus capable of performing multitude of therapy for secretion management and breath assistance therapy. The respiratory care apparatus comprises an electromechanical air router assembly (EARA) and an interfacing assembly. The EARA includes independent first and second pressure generating sources for assisted inhalation/insufflation and assisted exhalation/exsufflation process. The interfacing assembly includes a patient interface port and a patient interface tube. The interfacing assembly forms two pneumatically separate paths. The respiratory care apparatus is configured to generate alternate positive and negative pressure at the patient interface port for assisted inhalation/insufflation and assisted exhalation/exsufflation processes respectively. The assisted inhalation/insufflation and assisted exhalation/exsufflation processes are carried out independently through separate conduits/passages to reduce contamination and infection. Further, the respiratory care apparatus comprises a garment which oscillates due to alternate positive and negative pressure generation and provides therapy to the patient.

摘要： Dispensing systems for a ventilator circuit having a ventilator flow circuit with a normal inhalation flow path with a heat and moisture exchanger (HME), a flow sensor in communication with the ventilator circuit, an automated drug dispensing system with an actuator and a pressurized canister residing upstream of the HME, a bypass inhalation flow path residing downstream of the pressurized canister, and at least one electromechanical valve residing in the inhalation flow path to selectively open the valve which can be normally closed to define a closed bypass path. At least one controller opens the at least one electromechanical valve to open the bypass inhalation flow path and close the normal inhalation flow path through the HME only when the flow sensor indicates air flow is in an inhalation direction. Once the valve is open, the actuator dispenses medication through the bypass inhalation flow path to the patient.

摘要： An active exhalation valve for use with a ventilator to control flow of patient exhaled gases. The valve includes a patient circuit connection port, a patient connection port, an exhaled gas port, a pilot pressure port, and a valve seat. The valve further has a movable poppet with inner and outer bellows members and a bellows poppet face. An activation pressure applied to the pilot pressure port extends the bellows members to move the poppet face into engagement with the valve seat and restrict flow of patient exhaled gases to the exhaled gas port, and the reduction of the activation pressure allows the bellows members to move the poppet face away from the valve seat and out of engagement with the valve seat to permit flow of patient exhaled gases to the exhaled gas port, thereby controlling the flow of patient exhaled gases from the valve.

摘要： An apparatus to measure pulmonary blood flow and cardiac output ({dot over (Q)}) comprising: a) a breathing circuit which, at exhalation, keeps exhaled gas separate from inhaled gas and at inhalation, when VE is greater than first gas set (FGS) flow, results in a subject inhaling FGS first and then a second gas set (SGS), for the balance of inhalation; b) a gas sensor for monitoring gas concentrations at the patient-circuit interface; c) a gas flow control means for controlling the rate of EGS flow into the breathing circuit; d) machine-intelligence consisting of a computer or logic circuit capable of controlling the gas flow control means which receives the output of the gas sensor means and outputs pulmonary blood flow.

摘要： An assembly for modifying airflow into a nasopharyngeal airway of a patient. A valve assembly is adapted to attach to an airflow generator. A solenoid including a piston is mounted exterior to a feed tube. A butterfly valve is within the feed tube at the inlet. A pin is within the piston, and a shaft of the butterfly valve is bent to connect to the pin such that the solenoid can drive the butterfly valve. An exhalation valve is within the feed tube at the outlet, the exhalation valve adapted to slide axially within the feed tube and incrementally cover the outlet. Upon rotation of the butterfly valve, the exhalation valve thereby slides towards the mask side, wherein upon activation of both the airflow generator and a controller circuit, pressurized air from the airflow generator continuously enters the feed tube but is converted to a single, repeatable burst or rush.
