摘要： A hand-held, automated qualitative fit tester (QLFT) for establishing gas mask fit integrity. The automated QLFT may be configured to utilize a pressure source in combination with a cartridge and a nebulizer to generate aerosols having size distributions and concentrations that are substantially the same as OSHA-approved manual units. The QLFT may further include a cartridge that contains the aerosol solution used to test mask integrity. The cartridge may be configured to recapture solution that collects on the interior walls of the nebulizer. The automated QLFT may also be equipped with a microprocessor for executing sequences that are in substantive compliance with 29 CFR 1910.134 and for writing to a data storage device. The automated aspects of the invention can reduce or negate the need for operating personnel to repeatedly and manually actuate a squeeze ball and record results manually, as is required with present OSHA-approved hand-held aerosol generators.

摘要： A method and device for determining the transmuriality and/or continuity of an isolation line formed by a plurality of point contact ablations. In one embodiment, a method for determining the size of a lesion (width, depth and/or volume) is disclosed, based on contact force of the ablation head with the target tissue, and an energization parameter that quantifies the energy delivered to the target tissue during the duration time of the lesion formation. In another embodiment, the sequential nature (sequence in time and space) of the ablation line formation is tracked and quantified in a quantity herein referred to as the “jump index,” and used in conjunction with the lesion size information to determine the probability of a gap later forming in the isolation line.

摘要： A head form for testing a variety of respirators. The head form can prevent false leak failures by having a mask registration member upon which the mask under test is mounted, the mask registration member being self lubricating. In one embodiment, the registration member is an inflatable bladder. The bladder can be configured to limit lift away of the inflatable bladder from the recess, thereby mitigating leaks in the head form assembly. The bladder may be configured to limit roll away of portions of the bladder that register against the head form, thereby reducing or eliminating leaks between the inflatable bladder and the mask under test.

摘要： An ablation catheter system configured with a compact force sensor at a distal end for detection of contact forces exerted on an end effector. The force sensor includes fiber optics operatively coupled with reflecting members on a structural member. In one embodiment, the optical fibers and reflecting members cooperate with the deformable structure to provide a variable gap interferometer for sensing deformation of the structural member due to contact force. In another embodiment, a change in the intensity of the reflected light is detected to measure the deformation. The measured deformations are then used to compute a contact force vector. In some embodiments, the force sensor is configured to passively compensate for temperature changes that otherwise lead to erroneous force indications. In other embodiments, the system actively compensates for errant force indications caused by temperature changes by measuring certain local temperatures of the structural member.
摘要翻译：消融导管系统，其配置有在远端处的紧凑力传感器，用于检测施加在末端执行器上的接触力。力传感器包括与结构构件上的反射构件可操作地联接的光纤。在一个实施例中，光纤和反射构件与可变形结构配合，以提供可变间隙干涉仪，用于感测由接触力引起的结构构件的变形。在另一个实施例中，检测反射光强度的变化来测量变形。然后测量的变形用于计算接触力矢量。在一些实施例中，力传感器被配置为被动地补偿导致错误力指示的温度变化。在其他实施例中，系统通过测量结构构件的某些局部温度来主动地补偿由温度变化引起的错误力指示。
