Filed:

Mar 17, 2006

Appl. No.:

11/377673

Inventors:

Trinh Phung - Attleboro MA, US
Erich Dreyer - Bellingham MA, US
Douglas Moore - Westwood MA, US

International Classification:

B65D 19/00

US Classification:

248346030

Abstract:

A floor stand for a relatively small medical device. The floor stand stabilizes and/or levels the medical device when the device is on the floor. When the device is being carried or moved, the floor stand is completely underneath the device, so as to minimize the possibility of the stand coming into contact with an exterior person or item. Also, a method of stabilizing and/or leveling a small medical device.

Inventors:

Trinh Phung - Attleboro MA, US
Erich Dreyer - Bellingham MA, US
Douglas Moore - Westwood MA, US

International Classification:

A61M 27/00

US Classification:

604541000

Abstract:

A pressure indicator for a chest drainage unit is provided. The indicator includes an outer casing having a longitudinal axis and a first end with an opening exposed to ambient air and a second end with an opening coupled to communicate with the collection chamber inside a chest drainage unit for reading patient pressure. A linear force resistance element in the form of a spring compressed inside a bellows is disposed inside the outer casing and aligned along the longitudinal axis. An indicator cap is disposed inside the outer casing and coupled to a tip portion of the bellows element. The interior of the bellows communicates with the collection chamber pressure such that the spring and bellows expands and contracts inside the casing to indicate the degree of suction pressure in the collection chamber.

International Classification:

A61M 27/00

US Classification:

604541000

Abstract:

A modular chest drainage assembly is provided, having a collection module formed from a first base mold. The collection module defines a collection chamber having a patient fluid intake port. The assembly further includes a flow control module formed from a second base mold. A separate flow coupling is attachable to the collection module and flow control module to place the two modules in fluid communication. A pre-assembled pressure regulation module is coupled to the flow control module to regulate the pressure inside the collection module and flow control module. The assembly further includes a face plate, to which the collection module and flow control module are bonded such that the flow control module defines a first fluid flow pathway from the flow coupling to a suction port on the flow control module, for transmitting a suction flow from the collection chamber to the suction port.

Erich Dreyer - Bellingham MA, US
Douglas Moore - Westwood MA, US

International Classification:

A61M 27/00

US Classification:

604541000

Abstract:

An anti-spillover flow coupling for a chest drainage assembly including at least a first and a second flow chamber. The coupling includes an intake port adapted to couple to the first flow chamber and exit port adapted to couple to the second flow chamber. The coupling defines a flow passageway between the intake port and exit port. The flow coupling further includes an anti-spill means for preventing the flow of liquid between the first flow chamber and second flow chamber. The anti-spill means can include a valve means including a ball member and valve seat member, the valve means being open when a valve axis is aligned substantially against the direction of gravity. Or the anti-spill means includes at least one filter element disposed over one of the intake port or exit port, the filter element permitting the passage of gases but not liquids.

International Classification:

A61M 27/00

US Classification:

604541000

Abstract:

A pressure indicator for a chest drainage device includes an outer casing with a longitudinal axis and first and second end portions defining first and second openings. A flexible element is disposed inside the outer casing to define a collapsible pressure-holding inner space in fluid communication with the second opening. An indicator element is disposed inside the outer casing configured to translate along the longitudinal axis. The flexible element, indicator element and outer casing together define a variable interior space inside the outer casing in fluid communication with the first opening. A force resistance element is placed in the casing to resist the translation of the indicator element along at least one direction along the longitudinal axis when a pressure differential exists between the first and second openings.
