Inventor: PHAN VU
IPC: A61B19/02
Filed: 2003-09-04
Abstract: The present invention is a mechanical contrivance integrated into the closure of a sharps collector. It is intended to allow for the safe removal and disposal of a used pen needle from a pen syringe device. The pen syringe, with the used pen needle attached, is inserted into a passage of the specially designed port of the present invention. The pen syringe is then rotated counterclockwise about its longitudinal axis. The pen needle itself is constrained by at least one tooth, which only allows the pen needle one degree of freedom (linear displacement along its longitudinal axis). These conditions cause the pen needle to be unthreaded from the pen syringe, such that when the pen syringe is withdrawn from the port, a tang then blocks the pen needle from being withdrawn with the pen syringe, and the used pen needle falls into the sharps collector without the use of a secondary operation. The passage is angled at an angle of greater than 0 degree and less than 90 degrees to a top surface of the closure so that neither the at least one tooth nor the tang impedes the vertical transfer of the pen needle into the sharps collector by gravitational action.

IPC: B01D35/06
Filed: 2002-03-08
Abstract: A filter unit for coupling in-line with a transmission fluid line is provided for filtering ferrous and non-ferrous particulate matter from the transmission fluid. The filter unit includes a filter element (21) situated within a casing (12). The filter unit has an annular magnet (26) mounted on an end thereof. In an operational condition, the magnet is seated against an inner surface of the casing. As the filter becomes clogged, the filter element moves to a bypass position unseating the magnet from the casing. Fluid then bypasses the filter element but still flows around the magnet which continues to attract and trap ferrous particulate matter. A ferrous indicator flag (49) may be positioned on the outside of the casing when the filter element is in its operational position and is released and falls away as a visual indication of a clogged filter element in the bypass position.

Title: Pressure actuated flow control valve
Inventor: DIKEMAN W CARY
IPC: A61M39/10
Filed: 2003-12-08
Abstract: A pressure actuated flow control valve for an infusion catheter permits gravity flow of a liquid through the catheter and into a patient while resisting back flow of blood from the patient and into the catheter. The valve has a hemispherical body with an outstanding circumferential flange and a normally closed, diametric slit. The slit is longer on the convex outer surface than on the concave inner surface. Dome thickness diminishes in the area adjacent the slit, reducing total apical deflection upon collapse of the slit toward the concave surface. An inner orthogonal rib biases the slit closed. Upon application of a predetermined pressure, the slit opens toward the concave surface to permit forward fluid flow. At lower pressures, the slit closes to check fluid flow. Greater reverse pressure is required to collapse the slit toward the concave surface to permit reverse fluid flow.
