Abstract

A support hose applicator and method for applying and removing elastic tubular material from a limb of a patient comprises a resiliently expandable support ring having rotatable sidewalls, and a mandrel with elongated sidewalls on which the support ring fits. The hose or tubular material is applied to a patient by first pulling an open end of the hose over the mandrel. The support ring is then placed over the hose and mandrel. The hose is then rolled onto the support ring as the support ring is rolled along the mandrel. The hose is applied to a patient by rolling the support ring along the limb of the patient while holding a free end of the hose in place. The support ring comprises a plurality of ring segments rotatably mounted on a resiliently expandable band that is expandable to make the ring larger.

Claims

1. A support hose applicator for applying and removing elastic tubular material from a limb of a patient comprises a resiliently expandable support ring having rotatable sidewalls, the support ring having a contracted size wherein elastic tubular material of a predetermined diameter may be rolled onto the support ring on rotation of the ring sidewalls, the support ring having an expanded size wherein the ring and elastic tube rolled thereon are enlarged sufficiently such that the ring can be rolled over a predetermined limb of a patient to unroll the elastic tubes onto the limb.

2. A support hose applicator as in claim 1 wherein the ring comprises a plurality of ring segments rotatably mounted on a resiliently expandable band that is expandable to make the ring larger.

3. A support hose applicator as in claim 2 wherein the ring segments have generally round outer contours and an axial opening therethrough for mounting of the segments on the expandable band.

4. A support hose applicator as in claim 3 wherein the expandable band comprises an elastic cord formed in the shape of a closed loop.

5. A support hose applicator as in claim 3 wherein the ring segments have opposed axial ends that are contoured so as to permit angular engagement of opposed axial ends when they are formed into an annular ring.

6. A support hose applicator as in claim 3 wherein axial ends of at least some of the ring segments are inclined inwardly as the end surfaces extend radially from the axial center to the outer periphery of the ring segments.

7. A support hose applicator as in claim 3 wherein the length of the ring segments in an axial direction is greater at the axial center than at outer peripheral edges of the segments.

8. A support hose applicator as in claim 1 and further comprising a mandrel by which elastic tubular material can be rolled on the support ring, the mandrel having an elongated, axially extending surface that fits inside the support ring at least when the support ring is expanded, the exterior surface permitting the support ring to be rolled along the exterior surface with an end of the tubular material thereof so as to roll the tubular elastic material up on the support ring.

9. A support hose applicator as in claim 8 wherein the mandrel has a generally cylindrical or conical exterior surface.

10. A support hose applicator as in claim 8 wherein the mandrel has an outwardly extending flange at a distal end that restrains the support ring from rolling over that end of the mandrel.

11. A support hose applicator as in claim 9 wherein the mandrel exterior surface has the form of a truncated cone.

12. A support hose applicator as in claim 1 wherein the elastic tubular material is support hose and the limb is at least part of a patient'"'"'s lower leg and foot.

13. A support hose applicator for applying and removing elastic tubular material from a limb of a patient comprises a support ring having rotatable sidewalls on which the hose can be rolled, the ring comprising a plurality of ring segments rotatably mounted on a band that retains the segments in the form of a ring, the ring segments having round outer contours and an axial opening therethrough for mounting of the segments on the band.

14. A support hose applicator as in claim 13 wherein the band is expandable and comprises an elastic cord formed in the shape of a closed loop.

15. A support hose applicator as in claim 14 and further comprising an elongated mandrel on which the hose is rolled, the mandrel having an elongated outer surface on which an open end of the tubular material is mounted, the support ring fitting over the material and mandrel, the material being folded over the ring and rolled on the ring by rolling the ring on the mandrel.

16. A method of applying a tubular elastic material to a patient'"'"'s limb comprising:

providing an expandable support ring having rotatable sidewalls;

rolling the elastic material onto the ring;

inserting the limb into the support ring;

unrolling the elastic material onto the limb by rolling the ring along the limb with a free end of the tubular material in a fixed position on the limb so as to unroll the tubular elastic material along the limb; and

removing the support ring from the limb after the elastic material has been unrolled on the limb.

17. A method as in claim 16 wherein:

the tubular elastic material is rolled on the support ring by first pulling a distal end of the material over an elongated exterior surface of a mandrel;

placing the support ring over the tubular material on the mandrel;

rolling the tubular material on the support ring, starting with placement of the distal end of the tubular material on the support ring and rolling the support ring toward a proximal end of the tubular material;

whenever the support ring is rolled to a position adjacent a proximal end of the mandrel before the tubular material has been rolled up to the extent desired, sliding the support ring and attached portion of the tubular material back to a distal end of the mandrel and then recommencing to roll more tubular material on the ring by rolling the ring back toward the distal end;

removing the rolled up tubular material from the mandrel;

placing the desired limb in the center of the ring, holding an unrolled portion of the tubular material in position on the limb, and unrolling the tubular material along the limb; and

removing the support ring from the limb.
