BMC Medical Respiratory Gas Humidification Assembly Patent Application
Summary
BMC Medical Co., Ltd. filed patent application US20260108690A1 on December 18, 2025, for a humidification assembly configured to humidify pressurized respiratory gas. The assembly includes a liquid chamber with a tank and tank cover, featuring a shell with gas inlet and outlet ports on the same side surface, designed for integration into respiratory ventilation apparatus.
“The humidification assembly gas outlet port is configured to introduce the humidified and pressurized respiratory gas, via the second gas passage back into a main body of the respiratory ventilation apparatus.”
About this source
USPTO classification A61M covers devices that introduce or withdraw fluids from the body: infusion pumps, catheters, syringes, inhalers, wound drainage, dialysis equipment, and fluid-handling microfluidics. Every newly published application in A61M lands in this feed, around 205 a month. Applications publish 18 months after filing. Watch this if you compete in infusion therapy or drug delivery, file freedom-to-operate analyses for medical device startups, scout acquisition targets in cardiovascular or respiratory devices, or track hospital R&D arms that are quietly patenting clinical innovations.

Abstract
A humidification assembly configured to humidify a pressurized respiratory gas is provided. The humidification assembly may include a liquid chamber configured to accommodate one or more liquids, the liquid chamber including a tank and a tank cover. The tank cover includes a shell, a humidification assembly gas inlet port, a humidification assembly gas outlet port, a first gas passage including an output port, and a second gas passage including an input port. The humidification assembly gas inlet port is configured to introduce the pressurized respiratory gas, via the first gas passage, into the tank. The humidification assembly gas outlet port is configured to introduce the humidified and pressurized respiratory gas, via the second gas passage back into a main body of the respiratory ventilation apparatus. The humidification assembly gas inlet port and the humidification assembly gas outlet port are set on a same side surface of the shell.
