DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS
With reference to FIGS. 1, 2, 3 and 4, a polyvalent apparatus for physical therapy comprises a support 1 composed of a metallic structure 11 surmounted by a telescopic tower 12 with an inclined arm 13 to which a specific tool provided for treating a patient is fastened.
To the base of the metallic structure 11 four wheels 14 are fastened, free of rotating, capable of being oriented and blocked, which allow an easy displacement of the polyvalent apparatus along pathways of an hospital; the displacement is ensured by a big handle 15 integral with the tower 12. The wheels 14 are equipped with braking devices 16 actuated by a transverse bar 17 to guarantee a correct and solid installation to the edges of the patient's bed.
The telescopic tower 12, integral with the metallic structure 11 and centrally placed with respect thereto, can be extended through an oil-dynamic pump 18 connected to an hydraulic piston through a pipe 19.
The inclined arm 13 is telescopic and manually elongated by acting on a flywheel 20 placed on the head of the arm 13 itself. The tower 12 and the inclined arm 13 are equipped with a respective screw-type knob 21, 22 to block the stroke of the hydraulic piston (not shown) placed inside the tower 12 and of the screw-lock screw assembly (not shown) inside the inclined arm 13.
The projecting end of the inclined arm 13 is provided with an upper interface plate 23 connected to a beam 25 through a lower interface plate 24 integral with the beam 25. The pair of upper 23 and lower 24 interface plates allow rotating the beam 25 with respect to the inclined arm 13, around a vertical axis to the ground on which the apparatus rests. A pin 26 ensures locking the lower plate 24 with respect to the upper plate 23 next to certain positions rotated by a flat or right angle.
The manual rotation is allowed by unlocking the pin 26.
The ends of the beam 25 are occupied by a head plate 27, equipped with threaded interface holes (not shown), and with a sleeve 28 crossed by a cylindrical bore 29.
The support 1 bears specific tools for physical therapy by means of the beam 25.
A first tool 4 is used for performing the exercise of training with weights, exercise known as “press leg”, wherein the patient pushes a weight or contrasts a resistance with his leg's force.
With reference to FIGS. 5 to 9, the first tool 4 is composed of a linear sliding guide 41 supported by carter 42 connected to the beam 25 through a end plate 43 coupled with the plate 27 and through a pair of wings 44 equipped with through-hole which can be coupled with the hole 29 of the sleeve 28.
The linear sliding guide 41 is traveled by a slider 45 connected to a pair of anatomic housings for heels 46, over which there are two oscillating shapes 47 which allow flexure-extension movements of the tibia-tarsus articulation by means of an elastic abutment 48 independently acting on each oscillating profile 47 (FIGS. 7, 8).
A projecting section of the carter 42 is connected to a box 49 capable of being lifted, containing a group of elastic bands 50. Each elastic band 50 operates as resistance to the thrust movement of the lower limbs, having an end 51 fastened to a fastening plate 52 equipped with connections 53 arranged at different heights to calibrate the tooling with a certain pre-load, and a mobile end 54 connected to the slider 45 (FIG. 8).
Immediately below the plate 25 there is a strike-counter 55 coupled with the first tool 4, for detecting repetitions in re-education operations (FIG. 5).
A second tool 6 is used for performing the exercise of resistance of formation of the quadriceps muscle in the legs, exercise known as “leg extension”.
The second tool 6 is connected to the support 1 by means of the first tool 4 fastened to the beam 25, this latter one being rotated by a flat angle with respect to the configuration used for performing the exercise with the first tool 4, following: unlocking of pin 26; unlocking of lower plate 24 with respect to upper plate 23; manual rotation by 180° of beam 25; locking of pin 26.
With reference to FIGS. 10 and 11, the second tool 6 is composed of a vertical rod 61 ending with a plate 62 coupled with the end plate 43 of the first tool 4 through screw-type knobs. The vertical rod 61 operates as support for a horizontal bar 63, which is used as popliteal bearing for the patient's limbs. To the end of the bar 63, two telescopic arms 64 are connected, rotating with a device 65 which adjusts their movement amplitude. The projecting end of each arm 64 is equipped with a cylindrical device 66 which can be anatomically suited to the patient's foot back and equipped with seats 67 for housing a series of weights 68 necessary for changing the value of the resistance to be contrasted with the physical exercise.
A third tool 8 is used for performing the exercise of extending the affected limb keeping the eccentric contraction of the quadriceps, exercise known as “ECQ-Quadriceps Contraction Elastic Band”.
The third tool 8 is connected to the support 1 by means of the first tool 4 fastened to the beam 25, this latter one being rotated by a flat angle with respect to the configuration used for performing the exercise with the first tool 4, following a manual procedure identical to the one seen for applying the second tool 6.
With reference to FIG. 12, the third tool 8 comprises an horizontal supporting bar 81 integral with a central plate 82 directly fastened to the beam 25 though screw-type knobs. A shaft 83 is free of rotating in the seat obtained in two small arms 84 fastened to the end of the bar 81. The rotation of the shaft 83 is driven by a handle 85 lateral thereof; two winding coils 86 are keyed to the shaft 83, and wrap around a band 87 ending with an elastic section 88 connected to the end of a horizontal rigid bar 89, covered with a non-toxic rubbery material, which works as abutment for the user popliteal area.
The polyvalent apparatus for physical therapy performs the function of housing different tools used for re-educating specific muscle groups due to the rotation of the beam 25 and to the structural stiffness contribution given by the combination of two tools, 4-6 and 4-8.
A variation applied to the polyvalent apparatus for physical therapy of the invention respectively provides the second tool 6 and the third tool 8 directly connected to the rotated beam 25 and without using the first tool 4. In this case, the beam 25 must be sized to provide for the structural stiffness otherwise guaranteed by the combination with the first tool 4.
It is provided to motor the elongation of the telescopic parts, in particular the tower 12 and the inclined arm 13.
The polyvalent apparatus for physical therapy has been designed so that all parts in contact with the patient are protected by a material which can be easily interchanged and obtained inside hospitals (paper socks, tissues, etc.) in compliance with hygienic standards.
