Abstract
An apparatus is provided to prevent water ingress to a medical device with a housing. Such water ingress may originate, for example, from a connected humidifier. The apparatus consists of an endcap including at least one aperture for selective coupling with a compatible accessory. The end cap is constructed from panels which cooperate to provide an internal fluid passageway for diverting water from the point of ingress to the exterior of the housing.
Claims18
A liquid diversion assembly for a medical device that includes a housing, the liquid diversion assembly comprising:
- an end cap in association with the housing, the end cap comprising:
- a proximal panel proximal to the medical device in use, comprising a first interior surface and a first exterior surface;
- a distal panel distal to the medical device in use, comprising a second interior surface and a second exterior surface;
- at least one wall extending between the first interior surface and the second interior surface;
- at least one aperture for selective coupling with a compatible accessory,
- wherein the at least one aperture is between the second exterior surface and the second interior surface of the distal panel,
- wherein the end cap comprises at least one internal fluid passageway at least in part defined by the at least one wall, the first interior surface, and the second interior surface,
- wherein the end cap comprises a gap between the at least one internal fluid passageway and an exterior of the end cap, wherein the gap is in a position inferior to the at least one aperture,
- wherein the at least one internal fluid passageway is in fluid communication with the at least one aperture to divert liquid to an exterior of the housing through the gap.
A liquid diversion assembly for a medical device that includes a housing, the liquid diversion assembly comprising:
- an end cap in association with the housing, the end cap comprising:
- a proximal panel proximal to the medical device in use, comprising a first interior surface and a first exterior surface;
- a distal panel distal to the medical device in use, comprising a second interior surface and a second exterior surface;
- at least one wall extending between the first interior surface and the second interior surface;
- at least one aperture for selective coupling with a compatible accessory, wherein the at least one aperture is between the second exterior surface and the second interior surface of the distal panel,
- wherein the end cap comprises at least one internal fluid passageway in fluid communication with the at least one aperture to divert liquid to an exterior of the housing, wherein the internal fluid passageway is at least in part defined by the at least one wall, the first interior surface, and the second interior surface,
- wherein the medical device is a ventilator.
An apparatus for supplying a flow of breathable gas at a positive pressure for respiratory therapy, wherein the apparatus comprises:
- a pressure generator for generating the flow of breathable gas and supplying the flow to an outlet;
- a housing which contains at least the pressure generator;
- a liquid diversion assembly comprising:
- an end cap in association with the housing, the end cap comprising:
- a proximal panel proximal to the medical device in use, comprising a first interior surface and a first exterior surface;
- a distal panel distal to the medical device in use, comprising a second interior surface and a second exterior surface;
- at least one wall extending between the first interior surface and the second interior surface;
- at least one aperture for selective coupling with a compatible accessory, wherein the at least one aperture is between the second exterior surface and the second interior surface of the distal panel,
- wherein the end cap comprises at least one internal fluid passageway in fluid communication with the at least one aperture to divert liquid to an exterior of the housing, wherein the internal fluid passageway is at least in part defined by the at least one wall, the first interior surface, and the second interior surface,
- wherein the end cap of the liquid diversion assembly is configured to be secured relative to the housing containing at least the pressure generator.
