Patent CA-2665094-A1 (CA)
Inventor: BEATY TERRY
IPC: A61B5/151
Filed: 2007-10-12
Abstract: A lancet-sampler system is configured to automatically remove a protective cover (56) from a lancet (30) and automatically unpack a test pad (64) just prior to use. This minimizes the risk of injury and reduces the chance of cross-contamination between the lancet and the test pad. The lancet defines a capillary groove (36) for drawing body fluid from the incision via capillary action and a sample transfer opening (38) for collecting the fluid from the groove. A carrier tape (62) is coupled to the lancet. The carrier tape includes a test pad for analyzing the fluid. The tape is folded around the test pad to form an airtight package (66). The test pad is located at a position to align with the sample transfer opening when the tape is unfolded. The protective cover covers a portion of the lancet, and when the tape is pulled, the protective cover is automatically pulled from the lancet.

Title: Ophthalmic lens materials containing chromophores that absorb both uv and short wavelength visible light
Inventor: WEINSCHENK JOSEPH I III
IPC: C07D249/06
Filed: 2008-08-07
Abstract: To obtain polymeric lens materials that absorb both UV and short wavelength visible light, it is common to add separate UV-absorbing and short wavelength light-absorbing chromophores to the polymeric materials. However, having a single chromophore that absorbs both can reduce the number of components added to the lens material and reduce disruption to the primary polymer chain structure of the lens. The present invention relates to chromophores that absorb both UV and short wavelength visible light. The chromophores are particularly suitable for use in intraocular lens materials. The chromophores of the present invention relate to the formula: (see above formula) wherein A=H or CH3; X=O or NH; n=2-6; m=0-6; and R=H, C1-C4 alkyl, or C1-C4 alkoxy.

IPC: F16K15/00

Abstract: A tubing drain valve in a production tubing string, positioned above a pump, is operated to open drain ports in the housing for draining produced fluids from the production tubing when the pump is shut off. The drain valve incorporates a check valve assembly which is freely moveable within the drain valve to shift a sleeve to open and close the drain ports. An uphole end of the check valve assembly is above the sleeve and seals to the top of a sleeve to shift the sleeve downhole and open the drain ports. A downhole end of the check valve is positioned below the sleeve in the valve. When the pump is turned on, the downhole end of the check valve assembly moves uphole to seal to the sleeve, creating a positive force to lift the sleeve to block the drain ports. The produced fluids flow through the valve and the production tubing to surface. The positive force minimizes the effect of fouling of the valve due to debris above the valve which might otherwise result in failure to shift the sleeve uphole, leaving the drain ports open.
