Embodiment Construction

[0021] As discussed above, cross-contamination can be a substantial problem in devices used for respiratory flow and / or gas measurement. For example, in a typical ventilator system, in the event of an undetected single failure condition, infection can be passed from one patient to another by contaminating the pressure sensing tube connected to the flow sensor. Furthermore, conventional methods for preventing cross-contamination can require equipment to be disassembled and sterilized between successive uses, which can be time-consuming, expensive, and inconvenient in many operating settings.

[0022] Accordingly, the inventors have recognized and appreciated that it would be beneficial to provide systems and devices for respiratory flow and / or gas measurement that prevent infection or other contaminants from passing through the flow and / or gas sensor. The housing enters the pressure sensing tube. Accordingly, various embodiments relate to systems and devices in which filters a...

Abstract

An apparatus comprises a flow sensor configured to sense airflow between a respiration machine and a patient, a first connector configured to communicate air between the flow sensor and the patient, a second connector configured to communicate air between the flow sensor and the respiration machine, multiple pressure sensing ports configured for connection to pressure sensing tubes and configured to communicate gas pressure between the flow sensor and a pressure flowmeter, and a filter integrated with the flow sensor between the first connector and the pressure sensing ports and configured to communicate gas pressure therethrough while preventing contaminants from passing from the flow sensor to the pressure sensing tubes.

Description

field of invention [0001] The present invention generally relates to techniques for respiratory flow and / or respiratory gas measurements. More particularly, various inventive systems and devices disclosed herein relate to ventilator or ventilator systems having flow and / or gas sensors with integrated filter. Background technique [0002] Breathing flow and gas measurements are commonly performed in ventilators and ventilator systems. These measurements can be used, for example, to regulate the supply of breathable air to patients in an intensive care unit (ICU), or to monitor the breathing patterns of people undergoing treatment. [0003] Certain techniques used for respiration measurement are regulated by standards-setting organizations to ensure quality and safety. For example, the International Electrochemical Commission (IEC) defines standards for intensive care ventilators used in the ICU and the components connected to the ventilators. [0004] Among the IEC standa...
