20110066077 | BLOOD SAMPLING NEEDLE - A blood sampling needle has a shell, a trigger seat, a needle stand, an elastic resetter and a safety switching member. The shell is provided with inner wall, retaining space, needle outlet and insertion end. A through-flange is formed into the shell. The through-flange and inner wall form a release groove with a tapered end-face. The trigger seat is mounted into the retaining space in a moveable state. The trigger seat has a control end and a rod. An axial chamber is opened on the rod so that two elastic release blades are formed on the rod, and also accommodated correspondingly into the release groove. An abutting bevel edge is formed at the bottom of the elastic release blade, and mated with the tapered end-face of the release groove in an oblique surface. The present invention saves structural members, reduces fabrication cost with better safety and applicability. | 2011-03-17 |
20110066078 | PAIN MONITOR FOR A PATIENT UNDERGOING A MEDICAL PROCEDURE - A pain monitor for a patient undergoing a medical procedure includes a housing adapted to fit in a hand of the patient, a force sensor, and a battery-powered data processor. The patient is instructed to squeeze the housing with a force representing his level of pain. That force is measured by the sensor, acquired by the data processor and then wirelessly transmitted to an outside data receiver for further processing and recording. This device allows the patient to non-verbally express his perception of the level of pain which in turn allows a physician to adjust the course of the procedure or the level of pain-reducing medication. The pain monitor of the invention is particularly useful during a colonoscopy procedure. | 2011-03-17 |
20110066079 | PROSTHETIC DEVICE AND SYSTEM AND METHOD FOR IMPLANTING PROSTHETIC DEVICE - A prosthetic device includes one or more components configured to be disposed in a joint. The component includes at least one feature configured to provide information about the component. The information can be used to determine or create the relationship between the component and the joint and/or other components. This relationship may be used to evaluate and/or modify the expected performance of the prosthetic device and assist in determining the optimal relationship between one or more components and a patient's anatomy. | 2011-03-17 |
