Abstract

The invention contemplates an improved strap or bandage mounting of a socket element for removably engaged coupling of an ultrasonic transducer element to an afflicted limb. In a preferred embodiment, a radially flanged annular socket element is formed with outward lugs at axial offset from the flange, for preliminary assembly to a length of bandage material which has been cut to provide an opening for registration with the bore of the socket element, with the flange surrounding the opening and against one side of the bandage, while the outward lugs engage the other side of the bandage and also assure the desired registration. A softly compliant pad having a similar opening is removably securable to the flange-mounted side of the bandage to hold registration of the same central opening for all components and to afford direct access to an afflicted body-limb region through the central opening, when the thus-assembled bandage has been wrapped around the limb to securely position the socket element for reception of the transducer of a treatment head. Bayonet-locking lug formations on or near the transducer part of the head coact with lug formations on the socket element to retain the transducer during treatment of an afflicted bone through gel-coupled flesh at the situs of injury.

Claims

1. An orthopedic-treatment kit, comprising:

a length of flexible bandage material sufficient between longitudinally spaced inner and outer wrapping ends to circumferentially wrap an injured body limb, with the outer end in overlap with the wrapped limb and with means to secure the wrap at the outer-end overlap;

a pad of softly compressible material removably securable to said bandage at a location intermediate said ends, said pad having a central aperture and said bandage material having an aperture for registration with the aperture of said pad when in secured assembly thereto;

a flanged annular socket element having a bore with radially inward bayonet-locking formations, said socket element being removably securable to said bandage aperture and with the flange interposed between said bandage material and said pad; and

a transducer unit having a generally cylindrical mounting base and an axially projecting end, an ultrasonic transducer carried by said projecting end, said projecting end being sized for selective entry into and through the annulus of said socket element and through the aperture of said pad, and said base having formations for selective bayonet-locking engagement with the locking formations of said socket element upon predetermined passage of said transducer through the aperture of said pad.

2. The kit of claim 1, in which said pad and said bandage length and said socket element are preassembled to each other as a single one of the components of said kit.

3. The kit of claim 1, in which said socket element comprises an axially short cylindrical body with said flange extending radially outward of one axial end of said body.

4. The kit of claim 1, in which the bayonet-locking formations of said socket element are angularly spaced inward lug formations.

5. The kit of claim 4, in which the number of angularly spaced inward lug formations is four.

6. The kit of claim 1, in which said transducer is flat and mounted at said axially projecting end.

7. The kit of claim 1, in which the bayonet-locking formations of said mounting base are angularly spaced and are radially outward, and in which said socket element includes angularly spaced radially inward bayonet-locking lug formations corresponding to the bayonet-locking formations of said mounting base.

8. The kit of claim 7, in which the bayonet-locking formations of said mounting base are in like equal angularly spaced sets, the sets being at equal axial spacing whereby to accommodate bayonet-locked engagement with said socket element at different extents of passage through the annulus of said socket element.

9. The kit of claim 1, in which said transducer unit includes ultrasonic generator means connected for excitation of said transducer.

10. In combination, a socket element and an ultrasonic orthopedic-treatment head removably mounted to said socket element, for positioning said treatment head in orthopedic-treatment relation with an injured body limb, said socket element having a cylindrical annular body portion with a radially outward flange at one axial end and with a bore having a radially inward transducer-retaining formation at the opposite axial end, said orthopedic-treatment head comprising a generally cylindrical base adapted to be received in the bore of said body portion in axially located relation with said radially inward transducer-retaining formation, said treatment head further comprising a flat circular ultrasonic transducer and axially compressible elastomeric means positioning said transducer at such axial offset from said base as to apply said transducer with flexibly adapting and resiliently loaded contact with a body part to be treated, when the radially outward flange is mounted to or in close proximity to the body part.

11. A combination of claim 10, in which said radially inward transducer-retaining formation is a flange formation that is substantially circumferentially continuous.

12. The combination of claim 10, in which said radially inward formation is discontinuous at one angular location to define a slot for accommodating passage of an electrical lead to said treatment head when retained by said socket element.

13. The combination of claim 10, in which said radially inward transducer-retaining formation is a lug adapted for bayonet-locking retention of said generally cylindrical base.

14. The combination of claim 13, in which said lug is one of a plurality of angularly spaced lugs.

15. The combination of claim 14, in which said orthopedic-treatment head comprises at least one set of angularly spaced radially outward lug formations integrally formed with said base for selective bayonet-locking engagement with the lugs of said socket element.

16. The combination of claim 15, in which said set is one of a plurality of like axially spaced sets of radially outward lugs, whereby to afford axial selection of the bayonet-locked position of said head with respect to said socket element.

17. The combination of claim 16, wherein the axial space between adjacent sets is such that, upon bayonet-locking entry of said socket lugs in the space between adjacent sets, a slight interference-fit relation is encountered to frictionally retain the bayonet-locking engagement.

18. The combination of claim 13, in which said orthopedic-treatment head comprises at least one radially outward lug formation integrally formed with said base for selective bayonet-locking engagement with the lug of said socket element.
