Patent CA-2311468-A1 (CA)
Inventor: ROBINSON PHILIP J
IPC: A61B5/153
Filed: 2000-06-12
Abstract: A syringe (10) for drawing blood from a patient, the syringe haying a barrel (12) with a restricted free end (12a) and a needle assembly (14) releasably secured to the restricted free end. A plunger (16) is inserted into the barrel through an opposed end (12b), and retraction of the plunger within the barrel, away from the restricted free end is effective to withdraw blood from the patient when a needle (14a) with a sharpened free end of the needle assembly is appropriately inserted into the patient.  The syringe 10 is also provided with an annular needle guard (18) that surrounds the barrel and is slidable with respect thereto between a first position, in which the needle guard does not surround the needle, and a second position, in which the needle guard does surround the needle, to prevent the tip of the needle from injuring a person handling the syringe during times when the syringe is not being used to withdraw blood from a patient. The needle guard is made from a semi-rigid, transparent organic material, and has a diametrically opposed pair of inwardly extending projections (18a) that engage a diametrically opposed pair of outwardly facing recesses (14a) in the needle assembly when the needle guard is in its first position to prevent it from inadvertently moving to its second position. Hand squeezing of the needle guard along an axis extending perpendicularly to an axis between the projections is effective to disengage the projections and recesses, whereupon relative motion can occur between the barrel and the needle guard. This will occur, by gravity, if the syringe is held in a substantially vertical position with the needle up, whereupon the barrel will fall relative to the needle guard until the second position of the needle guard is reached.

Title: Pressure gauge with digital stepping motor and reusable transfer plug
Inventor: TAYLOR STEVEN R
IPC: A61F2/958
Filed: 1999-03-17
Abstract: This invention is a pressure gauge (10) for displaying the magnitude of fluid pressure generated within a syringe (12) or another pressurized system. The pressure gauge (10) is removably attachable to a syringe (12), and may be sterilized for reuse after each medical procedure. A piezo-resistive transducer (30) senses fluid pressure, and generates an electrical signal that changes in response to changes in said fluid pressure. The electrical signal is converted to digital signals by a microprocessor (34). A stepper motor (28) responds to the digital signals to control a pointer (40) that moves across a dial (42) to display the magnitude of the fluid pressure. A small lithium battery (52) that can withstand high temperatures supplies electrical power to the pressure gauge (10). A housing unit (44, 46), comprising a stainless steel bottom housing (44), and a transparent window (46), encases the components of the pressure gauge (10). After use, the pressure gauge (10) is placed in an autoclave, thereby sterilizing the pressure gauge (10) for reuse.

Title: Ultrasonic multi-channel flow measuring method
Inventor: SU TYAN KHAK
IPC: G01F1/66
Filed: 2000-12-29
Abstract: An ultrasonic flow rate measuring method comprises steps of measuring an inner diameter of a pipe in a manner to subtract a corrosive resistance layer and its possible thickness deviation from the maximum deviation of an inner diameter presented as a pipe size within the range of being able to be estimated, measuring a flow rate Q I  of the ideal circular section having the measured inner diameter based on the ultrasonic multi-channel flow rate measuring method, calculating a flow rate Q II of the remaining section according to a flow velocity distribution curve and adding the flow rate Q II to the flow rate Q I to calculate a total flow rate Q. Therefore, the method can enhance the accuracy of the flow rate measurement, if the section area of a pipe can't be measured, exactly, and the inner diameter of the pipe has a deviation due to an ovalness.

Title: A method for preemptive screen rendering
Inventor: CAMPBELL DON
IPC: G06T11/00
Filed: 2000-05-10
Abstract: A method of rendering screen of a computer display device under conditions requiring frequent repainting of the screen is disclosed. The display is a part of a computer system running an application under control of an operating system. The application detects the onset of conditions requiring frequent repainting of the screen by checking messages sent by the operating system to the application's message queue. The application then starts the repainting of the screen based on the information retrieved from the queue while checking periodically the message queue to see if the originally detected conditions still apply. If this is the case, the application terminates the original repainting operation and starts a new repainting operation based on the updated information retrieved from the message queue. This cycle is repeated until it is determined that the originally detected conditions no longer apply, in which case a final complete repaint of the screen takes place. The method is particularly useful for the display of a graphically complex scene during a navigation operation, such as panning or zooming, when complete repainting of the scene as the navigation progresses fails to provide to the user an acceptable visual feedback of the navigation progress.
