Abstract:
Apparatus for diagnosing an inflammatory condition relating to periodontitis, comprising means (1, 3) for measuring and recording temperature in connection with a periodontal pocket. The apparatus further comprises measuring means (17) with a graduated scale for measuring the depth of the periodontal pocket and in association herewith also provided with means (5) for measuring and recording the temperature difference between the bottom and the mouth of the periodontal pocket.
Abstract:
A periodontal probe (10) for measuring the distance from an occlusal surface of a tooth to the base of the gingival sulcus in a gum in which a disc (100) is movably mounted on the probe (10), said measurement being taken from the disc (100) on the surface of the tooth to the base of the gingival sulcus pocket.
Abstract:
An intra-oral measurement probe includes a hand-held unit having a body (210) with a tubular sleeve (222) extending from its front end. A removable probe tip (225) is within the sleeve and has a forward portion that protrudes past the front end (222A) of the sleeve, and is movable in the sleeve. A wire (233) has its front end coupled to the rear portion (238) of the probe tip, the wire extending rearwardly into the body. A spring (239) biases the probe tip and wire, with substantially constant pressure, against rearward movement with respect to the sleeve. A transducer (250) in the body is coupled to the wire and generates electronic measurement information representative of the position of the probe tip within the sleeve. A transmitter (272) responsive to the electronic measurement information for transmitting through-the-air signals representative of the electronic measurement information to a remote receiver and recorder.
Abstract:
To measure the biological activity of an experimental animal (T), the experimental animal (T) is kept on the platform (P) of a physical-electronic sensor (PES), for example in a cage (K) on which it is free to move. The balance (W) transmits the data (D) relevant to the kinetic activity of the experimental animal (T) to an evaluation unit (AE) which calculates the mean value of the activity (A &cir& NOt ) and the variation in weight ( DELTA g). Downstream of the evaluation unit (AE) can be connected an output unit (2G) which represents the data (D) and/or the calculated values (A &cir& NOt , SIGMA A &cir& NOt , DELTA g, s) graphically. The physical-electronic sensor is preferably an electronic balance based on the principle of electromagnetic force compensation.
Abstract:
A fall alert system (100) for informing monitoring personnel at a remote location when a monitored person falls. In one embodiment, a monitoring device (120) is positioned proximate a bed. A harness (36), having a ferromagnetic shunt (34) at one end, is attached to the person to be monitored. While the person is lying in bed, the shunt (34) is attached to a sensing means (18). When the monitored person is about to fall out of bed, the shunt (34) detaches from the sensing means (18), alerting monitoring personnel. Another embodiment is disclosed for monitoring mobile persons that wander from room to room in their home or a facility.
Abstract:
The knee joint analyzer has means (34) for fixing the thigh and femoral condyles and means (36) for fixing the foot and malleoli of the patient. Said fixing means (36) are connected to an axial load and torque loading mechanism (37) for applying incremental loads and torques to the knee joint via load and torque transducers (2, 3, 4) which can be continuously measured, amplified and registered on a plotter (21) allowing the assessment of translational stability in the sagittal and coronal planes and rotational stability in the coronal and transverse planes of the knee joint of the patient.
Abstract:
A device (10) for measurement of laxity of the knee comprises a thigh support (12) and a foot support (13) so arranged that the leg of the patient will be bent at the knee when the patient's thigh is resting in the thigh support (12) and his foot is strapped to the foot rest (13). A potentiometer (26) measures movement of the tibial tuberosity of the patient's leg relative to the patella, and a strain gauge mounted on plate (15) measures the force applied by a patient seeking to straighten the leg such as by tensioning the quadriceps muscle. A computer (9) plots and displays a graph (8) or other output of the force applied against the relative movement between the tibial tuberosity and the patella.
Abstract:
A movable plate (6) which rests through springs (5) on a base (1) which itself bears on the ground by means of height adjustable supports (2, 3) is provided with a spherical bubble level (8), with marks AA', BB', CC', DD', which define the positioning of the feet on said plate and with a removable setting system (18) with respect to the transversal line AA'. Application to the correction of equilibrium anomalies.
