Problems solved by technology

[0005] Poor manual techniques using BVM can cause problems
Specifically, overpressurization of the compression bag can increase the pressure and flow rate of the breathing gas beyond optimal levels and in the worst case may injure the patient and in some cases may compromise safe levels such as causing air into the stomach
Although some solutions have been proposed, such as placing a pressure relief valve in the flow path between the compression bag and the breathing mask, the final ventilation is not always effective and there is no tactile or other feedback to the user to alert them Need to ease the pressure they put on

Embodiment Construction

[0037] Figure 1A with Figure 1B A pressure safety device (PSD) 10 is shown in its intended position within a standard bag valve mask (BVM) assembly 50 constructed in accordance with the principles of the present invention. The BVM 50 includes a compression bag 52 , a reservoir bag 54 connected to the compression bag by a reservoir valve 56 , a positive end-expiratory pressure (PEEP) valve 58 , and a pressure relief valve 60 . Compression bag 52 , PEEP valve 58 and pressure relief valve 60 are all connected to manifold 62 having connector port 64 for removably receiving respiratory mask 70 . Respiratory mask 70 typically has an air cushion 72 on one surface for seating over the patient's mouth and nose in use, and a connector fitting 74 for removably mating with connector port 64 of manifold 62 . Generally, the connector port 64 on the manifold 62 will be a male connector and the connector fitting 74 on the respirator 70 will be a female fitting, but the invention can be ad...

Abstract

A pressure safety device is used with a bag valve mask (BVM) for preventing over-pressurization. The BVM includes a bag assembly having a bag connector for detachably mating to a mask connector on a patient mask. The pressure safety device has a housing with a bag port, a mask fitting, and a flow path from the bag port to the mask fitting. The bag port detachably connects to the bag connector on the BVM, and the mask fitting detachably connects to the mask connector on the BVM. The pressure safety device includes an automatic flow reduction valve located on the flow path in the housing and impedes flow when pressure on a bag connector side of the valve exceeds a maximum threshold value.

Description

[0001] cross reference [0002] This application claims the benefit of U.S. Provisional Application No. 62 / 679,301, filed June 1, 2018, which is incorporated herein by reference. Background technique [0003] 1. field of invention . The present invention generally relates to medical devices and methods. More specifically, the present invention relates to the field of breathing gas delivery using manual resuscitators. [0004] Bag valve mask (BVM) resuscitators have long been used to artificially ventilate patients who cannot breathe spontaneously, such as those in cardiac arrest, in respiratory distress, under anesthesia, and the like. A conventional BVM has a compression bag that the user manually compresses to pressurize and deliver breathing gas to the patient through a breathing mask worn over the patient's mouth and nose. [0005] Poor manual techniques using BVM can cause problems. Specifically, overpressurization of the compression bag can increase the pressure a...
