摘要： A sample retention apparatus for use in a device for measuring hemostasis. The device for measuring hemostasis may include a sample articulation apparatus including a guide shaft coupled for articulating motion to a drive motor, a sample carrier secured to and axially moveable along the guide shaft between a sample ready position, a sample testing position and a sample ejection position. The sample carrier therefore articulates in unison with the articulating motion of the guide shaft. A measuring apparatus may include a sensing column. The sample retention apparatus may include a sample cup defining a volume within which a sample may be disposed. The sample cup may be adapted to be operably positioned within an aperture formed within the sample carrier. The sample testing apparatus may also include a sample pin that is engageable with the sensing column. The sample pin may include a tip portion for extending into the sample cup. The sample pin may also include a flange extending radially outwardly from the tip portion for substantially completely enclosing the sample space during measurement of hemostasis.

摘要： A method and apparatus are provided for measuring hemostasis. The apparatus includes a torque sensing column having a torque sensing element and a drive ring disposed around a body of the column and in registration with the column so as to allow rotation of the drive ring around a longitudinal axis of the column. The apparatus further includes a first guide shaft rigidly secured to the drive ring, the guide shaft extending parallel to the longitudinal axis of the column and a cup holder movably attached to the guide shaft, allowing the cup holder to move parallel to the longitudinal axis of the column. The apparatus also includes a sample cup adapted to engage the cup holder on a outer surface and the torque sensing element of the torque sensing column on an inner surface.

摘要： The invention discloses a method and apparatus for effectively localizing a stone and targeting a shock wave in connection with extracorporeal shock wave lithotripsy ("ESWL"). The technique disclosed by this invention can be adapted for use in connection with any conventional lithotripter. In this invention, an array of at least 3 and preferably 4 or more pressure transducers are used to sense the reflection from the target in response to an initial shock wave or ultrasonic wave. The sensor readings are then temporally shifted relative to one another in such a way as to maximize correlation between the signals from each sensor. The required time shifts for maximum correlation are used to calculate the differences in arrival times of reflected waves at the sensors. By knowing the original location of the sensors and establishing the time differences at which the reflected wave reaches the different sensors, a technique is disclosed to determine the vector coordinates extending between the target location and the focal point of the lithotripter.
