Filed:

Dec 3, 2003

Appl. No.:

10/726782

Assignee:

International Classification:

B62D 1/185

US Classification:

74493, 464162

Abstract:

Apparatus and methods for transporter shaft coupling and decoupling to assure alignment of a user interface with a control shaft through matching asymmetric cylindrical surfaces and alignment of an upper shaft segment and a lower shaft segment with ribs meshing with grooves on rings attached to the upper shaft. A tone confirms proper connection. Alignment apparatus is protected from damage associated with torques applied to the control shaft by tab features designed to first give way before other damage is incurred and from moisture by apparatus that seals the connection between upper and lower shaft segments. The user is protected from sudden loss of control by requiring the user interface to execute a sequence of linear and rotational manipulations during assembly of the shaft.

Appl. No.:

10/626468

Inventors:

R. Arling - Windham NH, US
J. Field - Bedford NH, US
John Heinzmann - Manchester NH, US
Jeffrey Hill - Brookline NH, US
Michael Slate - Merrimack NH, US

International Classification:

B62D057/00

US Classification:

180/007100

Abstract:

A method for attaching a carrier, such as a trailer, to a dynamically balanced transporter. The carrier is attached to the transporter with a pivot. The pivot axis of the carrier is coincident with the axis of rotation of the wheels of the transporter. This method of attachment minimizes the impact of the trailer on the ability of the transporter to maintain dynamic balance and control.

International Classification:

F04B 43/12
G01F 1/66

US Classification:

417313, 417476, 417412, 7386118

Abstract:

A peristaltic pump, and related system method are provided. The peristaltic pump includes a cam shaft, first and second pinch-valve cams, first and second pinch-valve cam followers, a plunger cam, a plunger-cam follower, a tube receiver, and a spring-biased plunger. The first and second pinch-valve cams are coupled to the cam shaft. The first and second pinch-valve cam followers each engage the first and second pinch-valve cams, respectively. The plunger cam is coupled to the cam shaft. The plunger-cam follower engages the plunger cam. The tube receiver is configured to receive a tube. The spring-biased plunger is coupled to the plunger-cam follower such that the expansion of the plunger cam along a radial angle intersecting the plunger-cam follower as the cam shaft rotates pushes the plunger cam follower towards the plunger and thereby disengages the spring-biased plunger from the tube. A spring coupled to the spring-biased plunger biases the spring-biased plunger to apply the crushing force to the tube.

International Classification:

G01F 1/00

US Classification:

348135

Abstract:

An apparatus, system and method for regulating fluid flow are disclosed. The apparatus includes a curved, elongated support member elastically deformable and having first and second ends. The apparatus also include an opposing support member configured to position a tube against the curved, elongated support member between the first and second ends. Deformation of the curved, elongated support member by movement of the first and second ends toward each other reduces an internal volume of the tube.

International Classification:

A61M 5/168

US Classification:

417282, 417302

Abstract:

A pump for pumping fluid includes a tube platen, a plunger, a bias member, inlet and outlet valves, an actuator mechanism, a position sensor, and a processor. The plunger is configured for actuation toward and away from the infusion-tube when the tube platen is disposed opposite to the plunger. The tube platen can hold an intravenous infusion tube. The bias member is configured to urge the plunger toward the tube platen.

Abstract:

A peristaltic pump, and related method, are disclosed that includes a cam shaft, a plunger-cam follower, a tube receiver, a spring, a plunger, a door, and a plunger lift lever. The cam shaft includes a plunger cam. The plunger-cam follower engages with the plunger cam of the cam shaft. The spring provides a bias and the plunger is biased toward the tube receiver by the spring. The plunger is coupled to the plunger-cam follower where expansion of the plunger cam along a radial angle intersecting the plunger-cam follower as the cam shaft rotates actuates the plunger away from the tube receiver. The door lever can be actuated between a first position and a second position. The plunger lift lever is coupled to the door lever to actuate the plunger away from the tube receiver when the door lever is actuated to the second position.

Abstract:

A peristaltic pump is disclosed that includes a plunger, a spring, an actuator, a position sensor, and a processor. The plunger actuates toward and away from a tube. The spring biases the plunger toward the tube. The actuator actuates the plunger away from the tube and mechanically engages and disengages from the plunger. The position sensor senses a position of the plunger. The processor receives the sensed position of the plunger and estimates fluid flow within the tube using a first position of the plunger when the actuator is engaged with the plunger and a second position of the plunger when the actuator is disengaged from the plunger.
