Abstract
A chamber adaptor and a manufacturing method thereof. The chamber adaptor includes: a housing provided with a gas inlet, a gas outlet, a chamber inlet, and a chamber outlet, where the gas inlet is configured to be removably connected to a main board device, the gas outlet is configured to be removably connected to a respiratory pathway, the chamber inlet is configured to be removably connected to an input end of a chamber for storing liquid and the chamber outlet is configured to be removably connected to an output end of the chamber, the chamber adaptor further includes a control circuit and at least one sensing apparatus, where the at least one sensing apparatus is arranged on one end of the control circuit closer to the gas outlet and extends into a gas output channel.
Core Innovation
The invention provides a respiratory humidifier chamber adaptor having a housing with a gas inlet and a gas outlet, and with a chamber inlet and a chamber outlet configured to be removably connected to an input end and an output end of a chamber for storing liquid. The gas inlet is configured to be removably connected to a main board device, and the main board device is configured to provide oxygen and compressed air to the chamber adaptor, while the gas outlet is configured to be removably connected to a respiratory pathway.
A control circuit is included in the chamber adaptor, with a first end and a second end opposite each other. A sensing apparatus is provided at the first end and extends into a gas output channel formed between the gas outlet and the chamber outlet, where the space defined by an inner wall of the gas output channel comprises only the sensing apparatus, and the sensing apparatus is configured to detect a temperature of the gas passing through the gas output channel and deliver the detected temperature to the main board device.
To improve reliability during molding and operation, a first supporting element, a second supporting element, and a third supporting element are formed on the control circuit in contact with a surface of the control circuit to improve the strength of the control circuit and support the circuit board within a mold of the chamber adaptor to prevent the control circuit from warping. The disclosed implementations further include reducing heat transfer from the housing to improve temperature accuracy, configuring a connecting wire to limit thermal conduction, and providing sealing elements and exposed conductive contacts to protect against environment and gas leaks.
Claims Coverage
The independent claim (clm-00001) defines three inventive features: a removably connectable chamber adaptor interface, a control circuit with sensing apparatus extending into a gas output channel, and supporting elements formed on the control circuit for molding strength and warping prevention.
Removably connected chamber adaptor providing oxygen and compressed air
A housing provided with a gas inlet, a gas outlet, a chamber inlet, and a chamber outlet, where the gas inlet is configured to be removably connected to a main board device that provides oxygen and compressed air to the chamber adaptor, the gas outlet is configured to be removably connected to a respiratory pathway, the chamber inlet is configured to be removably connected to an input end of a chamber for storing liquid, and the chamber outlet is configured to be removably connected to an output end of the chamber.
Control circuit delivering temperature detected in the gas output channel
A control circuit having a first end and a second end opposite each other; wherein the at least one sensing apparatus is provided at the first end and extends into a gas output channel formed between the gas outlet and the chamber outlet, the space defined by an inner wall of the gas output channel only comprises the at least one sensing apparatus, the at least one sensing apparatus is configured to detect a temperature of the gas passing through the gas output channel, and the second end of the control circuit is electrically connected to the main board device so that the control circuit delivers the temperature detected by the at least one sensing apparatus to the main board device.
Supporting elements to prevent warping in mold
