Abstract: A biopsy device for percutaneous tissue removal includes an elongated housing having an operational axis, a stylet hub slidably mounted in the housing, where the stylet hub is movable relative to the housing between a proximal, armed position, and a distal, fired position, the stylet hub having a stylet strike, a cannula hub slidably mounted in the housing alongside the stylet hub, and a spring-biased arming member. The cannula hub is movable relative to the housing between a proximal, armed position, and a distal, fired position. The arming member is moveably mounted to the housing proximal of the respective stylet and cannula hubs, and configured for manually-actuated movement from a relaxed, extended position to a loaded, compressed position to define a compressive arming stroke. The biopsy device also includes an arming member biasing spring that restores the arming member from the compressed position to the extended position.

Abstract: According to the invention, a compression depth sensor for measuring a compression depth comprises a first pressure transducer (30), attachable to a fixed element, a first liquid filled lumen (20), having a first fixed lumen end (21) attachable to the pressure transducer and a first movable lumen end (22) being movable between a first position and a second position, a distance between the first and second position defining the compression depth, whereby the first pressure transducer is adapted to measure the compression depth by measuring a change in liquid pressure in the lumen during movement of the first movable lumen end between the first position and the second position. A CPR apparatus according to the invention comprises such a compression sensor.

Abstract: Aspects of the present disclosure are directed toward obtaining a plurality of impedance-measurement signals while a set of at least three electrodes are concurrently contacting a user. Additionally, various aspects of the present disclosure include determining a plurality of pulse characteristic signals based on the plurality of impedance-measurement signals. One of the pulse characteristic signals is extracted from one of the impedance-measurement signals and is used as a timing reference to extract and process another of the pulse characteristic signals.

Abstract: An apparatus for detecting tissue hardness of a living body includes a housing, a cap, a bottom cover, a driving module, a buffering module, a spring pipeline, a push-rod and a detecting module, and the driving module includes a firing spring and a restoring spring, and the two springs have different rigidities so as to form a reciprocating structure of the firing mechanism. After the detecting module of a firing mechanism is triggered, the resilience of the restoring spring compresses the firing spring back to its firing length, so as to restore its position by a single driving point and allow users to complete the firing operation by one hand and simplify the operation of doctors to improve convenience and efficiency.

Abstract: In one aspect, the present disclosure relates to a method, including obtaining, by the fitness tracking device, motion data of the user over a period of time, wherein the motion data can include a first plurality motion measurements from a first motion sensor of the fitness tracking device; determining, by the fitness tracking device, using the motion data an angle of the fitness tracking device relative to a plane during the period of time; estimating by the fitness tracking device, using the motion data, a range of linear motion of the fitness tracking device through space during the period of time; and comparing, by the fitness tracking device, the angle of the fitness tracking device to a threshold angle and comparing the range of linear motion of the fitness tracking device to a threshold range of linear motion to determine whether the user is sitting or standing.

Abstract: A device for measuring a mechanical property of a tissue includes a probe configured to perturb the tissue with movement relative to a surface of the tissue, an actuator coupled to the probe to move the probe, a detector configured to measure a response of the tissue to the perturbation, and a controller coupled to the actuator and the detector. The controller drives the actuator using a stochastic sequence and determines the mechanical property of the tissue using the measured response received from the detector. The probe can be coupled to the tissue surface. The device can include a reference surface configured to contact the tissue surface. The probe may include a set of interchangeable heads, the set including a head for lateral movement of the probe and a head for perpendicular movement of the probe. The perturbation can include extension of the tissue with the probe or sliding the probe across the tissue surface and may also include indentation of the tissue with the probe.

Abstract: A biological testing device includes a housing body having a meter storage compartment, and a testing meter that is disposed in the meter storage compartment and that operates with a biosensor strip which is disposed after being used. The housing body further has a waste storage compartment that is separated from the meter storage compartment and that has a waste take-out opening, and an insertion hole for inserting the used biosensor strip into the waste storage compartment. The waste take-out opening is larger than the insertion hole. The waste take-out opening is normally closed and is openable for permitting taking out of the used biosensor strip from the waste storage compartment.

Abstract: A cytological cell sample collection, storage, and transport device is disclosed. The device comprises a sheath, a collection assembly, a base, and a containment vial. The collection assembly is slideably coupled to the base to expose a swab head comprising the collection assembly. The containment vial may be configured to enclose the sheath and collection assembly within the internal volume defined by the containment vial and the base.
