摘要： A torque device for selectively gripping a medical guidewire. The device includes a housing, an actuator slidably mounted on the housing, and a resilient member biasing the actuator. A lumen dimensioned to receive the guidewire extends through the housing and actuator. The resilient member biases the actuator from a first position in which the lumen portions are aligned, toward a second position in which the lumen portions are misaligned. The actuator may include a catch that interferes with a stop of the housing to retain the actuator within the housing. The actuator may be oblong or otherwise shaped to maintain the lumen portions in substantial alignment in a longitudinal direction. Preferably, at least a portion of the lumen is teardrop-shaped in cross-section. The housing may include circumferentially or longitudinally extending ribs defining an outer grasping surface. Frusto-conical cavities may be defined at entry and exit ends of the lumen.

摘要： A blood containment device for use with a vascular entry needle provides visual and tactile confirmation that a blood vessel has been properly entered. The device includes a blood visualization chamber defined by a compliant member which provides a visual indication that a needle connected to the device has accessed a selected blood vessel. The blood visualization chamber is vented to allow air to escape therefrom as it is displaced by blood entering the visualization chamber, while a gas permeable membrane in communication with the vent to prevent significant blood from escaping from the blood containment device. A sealing member formed on an outer surface at one end of the compliant member works in conjunction with the gas permeable membrane to prevent significant leakage of blood from the device. The compliant member pulsates with changes in blood pressure, thereby providing continuous tactile confirmation that the needle tip is properly positioned within the selected blood vessel. The device allows passage therethrough of an elongated medical instrument such as catheterization apparatus while preventing significant blood leakage from the device.

摘要： An inflation device including a handle mechanism configured to selectively engage and disengage threads within the device. In some instances the threads are configured to couple a plunger to a syringe body. The handle mechanism may be configured to (1) provide a mechanical advantage and (2) change the location and direction of the input force, thereby making the device easier to use.

摘要： A catheter securement device which automatically deploys one or more sutures to secure a catheter without requiring the practitioner to manually suture the catheter to the self-suturing anchor device. A ratchet mechanism having one or more rotatable ratchet members, which pivot, and a ratchet member engagement spring, which maintains contact between the teeth of the rotatable ratchet member and the teeth of the ratchet ring. A suture retention assembly is provided to maintain the position of the sutures to minimize disruption of the sutures before deployment of the sutures.

摘要： Prophylactic needle guards or sheaths for protecting medical needles and persons using the medical needless either before or after use of the needle. The prophylactic needle guards have a flared portion in order to provide safe insertion of a medical needle into a protective hollow body portion. The needle guard includes structures which are configured to engage at least one of a variety of differently sized and configured wing portions found in medical needles. The needle guard may include a pair of projections that engage corresponding holes within the wing portions of medical needles that includes wings too large to enter the flared portion. Alternatively or in addition to the projections, the needle guard may include one or more interior annular grooves disposed on an inner surface of the flared portion that engage the wing portions of medical needles that have wings that are small enough to enter the flared portion.

摘要： A syringe and method for use which may be selectively operated between a free position and a locked position. A triggering device configured with a trigger attached to the plunger of the syringe is employed. The triggering device includes a set of threads located on the plunger and a corresponding set of threads on the barrel of the syringe. Upon actuation of the trigger, the threads on the plunger are retracted from their position of engagement with the threads on the barrel, thereby placing the syringe in position for free movement of the plunger with respect to the barrel. The threads are biased in the engaged position. Thus, when the trigger is released, the threads on the plunger return to their position of engagement with the threads on the barrel. In the locked position, the plunger may be screwed into or out of the barrel by rotating the plunger, enabling the operator of the syringe to maintain strict control over the amount of pressure in the syringe. The triggering device employs a plurality of ramp and channel configurations which are disposed at approximately the same angle as the threads on the plunger and barrel. Thus, upon actuation of the triggering device, no net force results on the plunger which would cause movement of the plunger with respect to the barrel.
