DETAILED DESCRIPTION OF THE INVENTION

(13) Like components are designated by like reference numbers

(14) With reference to the drawings, there is shown a digital model of multi-level pinch dynamometer or gauge apparatus 10 according to first embodiment of the invention.

(15) The apparatus 10 includes a gauge head 11, a 5-position multi-level rack 12, an internal transducer 13, a stationary mechanism 25 (including an upper plate 26 with a pinch pad 14), a bottom pinch pad or plate 15, and a digital display 16.

(16) FIGS. 1, 3 and 5 include an extra bottom plate 15 to clearly depict its configuration.

(17) The apparatus 10 is used to measure pinch strength, and constitutes a 5-position pinch grip gauge.

(18) The five positions are one stationary or fixed, and four variable.

(19) The gauge head 11 may be either hydraulic or electronic.

(20) The gauge head 11 displays strength readings, calculated results, and user demographics on the display 16.

(21) The gauge head 11 contains a mechanism (not shown) for converting raw pressure, force, or electronic signals into useable data points.

(22) The transducer 13 is a force or pressure transducer to initiate and transmit force or pressure to the gauge head 11.

(23) The transducer may be a load or pressure cell 13 (electronic) or a bellows (hydraulic).

(24) The multi-level rack 12 is used for accommodating the bottom pinch plate 15.

(25) The multi-level rack 12 comprises a four-position rack.

(26) In FIGS. 1, 3 and 5, the bottom pinch plate 15 is shown in two positions (unattached to the rack 12 and also mounted in the rack 12) merely for illustrative purposes only.

(27) The multi-level pinch dynamometer apparatus 10 measures pinch strength, comprising: the multi-position pinch grip device; a gauge head 11; transmission means 13 operably connected to the grip device and the gauge head 11 for transmitting pressure or force from the grip device to the gauge head 11; the gauge head 11 displays readings indicative of the pressure or force; the grip device includes a fixed stationary first mechanism 25 and a multi-position mechanism for quick insertion and removal therefrom of a second mechanism 15; and the first and second mechanisms 25 and 15 being pinched together by a subject to generate the pressure or force; and methods of making using the apparatus 10.

(28) The multi-position mechanism comprises the rack which is disposed substantially perpendicular to the fixed stationary first mechanism 14; and the rack 12 includes a plurality of apertures 16, 17, 18 and 19 therein each of which is designed and dimensioned to temporarily retain therein the second mechanism 15.

(29) FIG. 6 is a perspective view of a second embodiment of a feedback model apparatus 20 where the gauge 21 faces toward the subject to enhance compliance and feedback.

(30) Spring plunger devices 27 in the rack 12 enable the easy-to-use, attach/detach features for the bottom paddle 15.

(31) Alternatively, the spring plunger devices 27 can be on or part of the paddle 15.

(32) FIG. 7 is a perspective view of a third embodiment in the form of a clinical model apparatus 30 where the gauge 31 faces away from the subject (toward the practitioner to block readings from the subject.

(33) FIG. 8 is a perspective view of the third embodiment in the form of in use without the bottom pinch pad or plate or paddle 15 to accommodate small hands (same pinch width as current conventional pinch gauges).

(34) FIG. 9 is a perspective view of the third embodiment in use with the paddle 15 in the multi-level rack 12 to accommodate large hands.

(35) FIG. 10 illustrates the rear view of the FIG. 8 apparatus 30.

(36) FIG. 11 shows a fourth embodiment in the form of an electronic clinical model apparatus 40 where the gauge display 41 faces toward the practitioner.

(37) FIG. 12 shows a kit of components 50 having a carrying case 51, the clinical model of the 5-position grip gauge apparatus 30, a hand dynamometer 52, and a range-of-motion finger-goniometer 53.

(38) The multi-level design accommodates all hand sizes.

(39) Furthermore, the multi-level design is used for performing more tests and protocols than single-level pinch dynamometers conventionally in use.

(40) Also, the apparatus 10, 20 or 30 is used to prevent spurious readings which may be intended by the person being tested.

(41) The invention covers clinical (gauge facing away from the subject) models. and feedback (gauge facing toward the subject) models.

(42) The invention also covers hydraulic models with a bellows mechanism (and any other mechanism including a spring) to transmit pressure (force) to the gauge.

(43) The invention also covers digital models with a load cell or pressure sensor mechanism (and any other mechanism) to transmit pressure (force) to the gauge.

(44) The invention also covers a 5-position mechanism using numerous methods of quick insert and removal of the paddle from the rack.

(45) The invention not only covers a 5 position apparatus (1 stationary and 4 variable) as well as other configurations (1 stationary, and 1, 2, etc. variable).

(46) The digital model gauge head displays strength readings, calculated results, and user demographics.

(47) The digital model gauge has a series of up/down and left/right arrows which can be used by the practitioner to enter and retrieve data/information from memory to the gauge screen or through Bluetooth/wireless/or wired connection to a computer.

(48) While the foregoing describes only exemplary embodiments of the present invention, it is to be understood that the present invention covers all variations, modifications and changes thereof which will occur to those persons skilled in the art and to other persons after having been exposed to the present patent application.
