Abstract
A drip chamber for an infusion tube that includes a first end arranged to receive a drip tube, a second end including an exit port, at least one wall connecting the first and second ends, a space enclosed by the first and second ends and the at least one wall, and first and second lenses each directly fixed to said at least one wall.
Claims15
A drip chamber for an infusion tube, comprising:
- a first end arranged to receive a drip tube;
- a second end including an exit port;
- at least one wall connecting the first and second ends;
- a space enclosed by the first and second ends and the at least one wall;
- at least one lens being directly fixed to said at least one wall and configured for receiving light transmitted through the space and focusing and transmitting the light to another lens.
An optical imaging system for use with an infusion device, comprising:
- at least one light source for emitting first light;
- a drip chamber including first and second walls connecting first and second ends of the drip chamber, a space at least partially enclosed by the first and second walls and the first and second ends, a drip tube including an end that is located in the space, and at least one lens, said at least one lens being fixed to one of said first and second walls, said at least one lens arranged to transmit the first light to the space or receive the first light transmitted through the space;
- and
- an optics system including at least one image sensor for receiving the first light from said at least one lens and transmitting data characterizing the first light received from said at least one lens.
A drip chamber for an infusion tube, comprising:
- a first end including a drip tube;
- a second end including an exit port;
- first, second, third, and fourth walls connecting the first and second ends, wherein, in a cross-section orthogonal to a longitudinal axis of the drip tube, and form a rectangle enclosing a space;
- a drip tube including an end located in the space;
- and
- at least one lens being directly fixed to one of said first, second, third and fourth flat portions of said first, second, third and fourth walls.
A method of forming a drip chamber for an infusion tube, the method comprising:
- forming a first end arranged to receive a drip tube;
- forming a second end including an exit port;
- connecting the first and second ends with at least one wall and enclosing a space with the first and second ends and the at least one wall;
- providing at least one lens;
- and
- directly fixing said at least one lens to the at least one wall.
