Definitions

  • the present invention relates generally to a circulatory treatment system useful particularly in reducing the symptomatology and/or rehabilitation of a condition known as laminitis and other debilitating conditions in the leg of an equine or similarly structured animal.
  • One of the inventors in this application is a physician, who is a plastic and reconstructive surgeon and a wound healing specialist practicing for more than twenty-five years. In his practice he has encountered, studied, and treated all wounds on every location of the human body. His experience confirms that, whatever the mechanism of action, surgical, traumatic, neo-plastic, arterial disease, venous stasis, lymphatic, pressure, infectious, caustic, thermal, hypothermal, infarction, or (strangulation), every and all wounds are the direct result of the disruption of the circulatory system.
  • this one inventor has been a horse owner and rider for all of his adult life. He has first-hand knowledge of the condition of laminitis in horses. Over a period of fifteen years, he has made numerous attempts through consultations with veterinarians, attendance at conferences on the subject and a reading of the literature in an effort to find the underlying cause of the condition, the mechanism of injury, and perhaps a cure for the condition which baffles the equine world and the second largest cause of euthanasia in horses.
  • Laminitis is defined as the debilitating persistent and chronic condition of horses' hooves, which occurs when a critical mass of the interwoven complexes of connective tissue and blood vessels which hold the distal phalanx, P3, (coffin bone), to the inner surface of the keratinized hoof, fail to function. This is the result of a number of systemic and physiological causes.
  • the attachments separate, become “devascularized” and detach from the hoofs inner wall.
  • the strong pull of the deep flexor tendon on the coffin bone and the combination of the weakened attachments causes the bone to rotate downward creating severe pain, edema, venous congestion and lymphedema and significant debilitation. When left unchecked, this condition results in "founder” an old term for exposure of the coffin bone, through the sole of the hoof. This most commonly renders the animal unable to survive and usually results in euthanasia.
  • the incompetent valves and venous congestion cause dilation, pressure, and cause proteinaceous material to leak into the extra cellular and sub-cutaneous tissue, (a so-called "third space") resulting in more edema obstruction of the lymphatics.
  • This causes extremity swelling and tightening of the skin to maximum expansibility, thus impeding the arterial flow to that extremity.
  • Peripheral vascular disease i.e. arterial inflow obstructions, causes severe pain, anoxia, swelling and compromise to the overall vascular flow to the extremity.
  • the anoxia to the tissue causes lactic acidosis build up, cramping, electrolyte imbalances, cellular destruction and severe pain.
  • the external compression devices currently on the market decrease the congestion, drive the third space proteinaceous material and lymphatic drainage back into the venous system, relieving the skin of pressure, and improving the condition of wounds. All of these external devices mimic the return flow of the venous system as well as decompress and mobilize the third space edema.
  • the decompression of the lymphatic system thus reduces the overall pressure on the arterial system. This is all achieved by improving the gradient between the arterials and the venules, thus improving the overall extremity flow, oxygenation and wound healing. Oxygenation and arterial flow is necessary for all wounds to heal. Venous stasis in tissue can destroy an extremity.
  • a long recognized modality of venous decompression used for centuries is the application of leeches, which allow for continued arterial flow increasing oxygenation.
  • This tendon having the strongest dynamic attachments to the posterior of the coffin bone, begins its strong pull in the direction of flexion.
  • the counterbalance of the coffin bone is its strong attachment to the hoof wall by the lamellae. With the lamellae failing to adhere to the hoof wall, the flexor begins to rotate the coffin bone downward.
  • the construction of the extremity in a "digitaped" is such that the skeletal system suspends the animal in a perfectly balanced situation within the skin and the hoof.
  • a disruption of this perfect balance, as well as the pain and the edema associated with the imbalance, allows the flexor to work unchecked, pulling more lamellae free creating more swelling, more bleeding and more pain.
  • the increased edema within the confines of a closed space transmits more pain along the paratenon of the flexor tendon creating a secondary tendonitis.
  • the laminitis literature implicates a multitude of factors causing this condition: overfeeding, carbohydrate overload, stress, genetics, insulin resistance, injury, and Cushing's syndrome.
  • the cycle as described is pain, inflammation, venous stasis, more inflammation and more pain.
  • the secondary effects of the tendonitis render the animal so incapacitated as to be "paralyzed”.
  • the cycle must be broken either by stopping the edema (stasis), decongesting the arterial flow, or controlling the pain.
  • the treatment becomes symptomatic on all levels in an effort to salvage the animal.
  • the episodes were noted to have an increased intensity and duration with each exacerbation.
  • the one inventor has treated all the episodes which this horse has had with the usual symptomatic treatments: remove the grass, reduce the carbohydrate loads, rocker shoes, pads, analgesics, anti-inflammatories, etc.
  • navicular disease bowed tendons, tendonitis, pressure sores, wounds of all types, therapy for fractures, surgeries, post sports injuries, mobilization of exercise-induced, lactic acid build-up, edema of all sorts associated with racing, stocking up, pulmonary congestion, lymphedema, and performance and show injuries in the equine.
  • the NormaTec device prescribed for humans, when adapted to the equine, must be modified significantly.
  • the NormaTec device or similar supplier is basically a legging. It is a unitary circumferential device. The patient steps into or pulls the legging into or over a secondary garment - a cotton stocking extending from the lower extremity of the foot upward to the thigh.
  • the legging usually consists of four to five pneumatic chambers depending on the size of the patient.
  • This apparatus needs to be modified to accommodate circumstances unique to the equine application. For example,
  • the NormaTec device as it exists, has a long inflation time, and a long deflation time (both upwards of three minutes). This is because existing NormaTec tubing, which transfers the air pressure, has very small caliber diameter openings - less than one quarter inch(6.35mm). This restricts the inward and outward flow of the air, prolonging the treatment.
  • the devices which exist have no such interposed chamber between the initiation of air flow and the boot. Without this chamber, the flow is restricted and the time interval is longer. This fact coupled with the narrow tubing restricts the volume of the flow of air thus making the rapidity of the inflation and deflation prolonged.
  • an intermittent compressor or holding tank air chamber
  • the presence of an intermittent compressor (or holding tank air chamber) in association with the larger tubing will improve the volume of the flow of air on an instantaneous release into the boot and shortens the duration for a five chamber device to a total, in the range of between 15 to 20 sec per complete cycle, unlike the NormaTec device which takes up to 3 minutes to fill and/or complete a cycle.
  • the more rapid the compression/decompression cycle the more comfortable and tolerable the procedure is.
  • the treatment becomes more efficacious with a more rapid interval. This decreases the edema more rapidly in the extremity thus increasing the blood flow.
  • the interposed compressor or air chamber will ensure 15 seconds or less as a maximum inflation time and a compression (P H hereinafter) or decompression (P L hereinafter) interval of less than 15 to 30 seconds.
  • P H hereinafter
  • P L decompression
  • This, in conjunction with the larger tubing, will also allow for the more rapid inflow and outflow, shortening the overall duration of the treatment.
  • This more rapid interval of compression and decompression is necessary in an animal of prey, which is genetically geared to "fright or flight", and will allow for a more rapid accommodation to the device. The animal will tolerate rapid touching and decompression but would not tolerate grabbing and holding.
  • the NormaTec PCD device or similar device requires either stopping the air flow or interrupting the connection tubing in an emergency situation for decompression and removal of the garment. Because of the narrow tubing, decompression is very slow. The larger the garment, the more volume and the more difficult to deflate rapidly. This coupled with the small diameter of the tubing will create a problem for a horse. A fully inflated cycling garment will not allow the joints to flex since the animal is in a standing position. If the horse were to collapse without the garment deflating quickly enough, a fracture, dislocation or other permanent injuries could easily occur. A quick release valve, with a wide port, will be used to assist in the rapid decompression and quick removal of the compression wrap member, when necessary.
  • US 5,014,681 is directed to an apparatus for treating a human body part such as an arm or leg.
  • a pressurized fluid is introduced into an inflatable sleeve divided into a predetermined number of successively overlapping inflatable cells.
  • Each of the cells includes a port for inletting and outletting the pressurized fluid to enable an intermittent compression to the arm or leg.
  • US 5,174,382 describes a device that provides an artificial pumping means to apply pulsating pressure to the frog portion of a horse's hoof. The idea is to simulate the force applied to the frog when the horse walks so as to the collection of fluid where the coffin bone joins the hoof.
  • a system for the treatment principally of circulation problems in hoofed animals such as a horse.
  • the invention includes the provisioning of a wrap member, having a predetermined length and a plurality of inflatable chambers, including a most distal one and a most proximal one, positioned at respective intervals along the length of the wrap member.
  • the most distal one of the plurality of inflatable chambers is adapted to engage a compressible portion of the leg of the animal exposed within the hoofed area.
  • the wrap member further includes the means to releasably secure the wrap member to the leg of the animal;
  • the invention further requires the provisioning of a controllable pressure source which is connected to each of the inflatable chambers.
  • the methodology calls for manipulating the wrap member using the means for releasably securing the wrap member, to position and secure the wrap member about the leg of the horse.
  • the most distal one of the chambers engages the compressible portion of the leg of the animal exposed within the hoofed area.
  • the most proximal one of the chambers engages a higher portion of the leg of the animal in an area predetermined by the length of the wrap member.
  • the controllable pressure source is adapted to provide a plurality of repetitive cycles. Each one of the repetitive cycles comprises a first predetermined number of successive time intervals.
  • the controllable pressure source is further adapted to provide during each time interval during the repetitive cycles, either a predetermined pressure of a higher magnitude, P H , or of a lower magnitude, P L , to a respective one of the plurality of inflatable chambers in accordance with a predetermined wave pattern, wherein the predetermined wave pattern requires that during each time interval of the one of the repetitive cycles, at least two immediately adjacent inflatable chambers are at P H pressure and at least one of the inflatable chambers is at P L pressure.
  • the at least two immediately adjacent inflatable chambers at P H pressure over the time of each the repetitive cycle progress from the most distal inflatable chamber and the next most distal one to the most proximal one and the next most proximal one.
  • the invention further calls for the controllable pressure source to provide at least one ramp-up cycle extending over a second number of successive time intervals prior to the beginning of the repetitive cycles.
  • the ramp-up cycle comprises a varying combination of the inflatable chambers inflated at P H and P L in accordance with a predetermined sequence based on the predetermined wave pattern.
  • the invention still further calls for the controllable pressure source to provide at least one fill cycle prior to providing the at least one ramp-up cycle.
  • each of the inflatable chambers is filled at a pressure less than P H and typically, P L
  • the invention still further calls for the disposition of the most distal one of the plurality of inflatable chambers within a boot which is releasably secured to the hoof of the animal.
  • the boot is adapted to assist in the engagement of the most distal one of the inflatable chambers with the compressible portion of the leg of the animal.
  • the invention still further calls for the disposition of an inner sole pad between an upper surface of the most distal one and the compressible portion of the leg of the animal exposed within the hoofed area.
  • the pad facilitates the interaction between the bladder and the exposed area.
  • the invention identifies that the inner sole pad is adaptable to be impregnated with a variety of medications including vasodilatory and topical anesthesia medications; as well as adaptable to be a facilitator with an electronically charged medicament delivery system.
  • a compression wrap member 20 portion of the system of the present invention is shown prior to installation on the animal. It includes a garment section 22 with a series of bladders, not readily seen in this figure, interposed between the layers of the garment section.
  • the wrap member 20 includes a hoof covering segment 24 as well as means 26 for releasably securing the wrap member 20 to the horse's limb.
  • These typically comprise hook and loop, VELCRO or similar supplier straps available from "Seattle Fabrics", of Seattle, Washington or similar supplier and include respective D-rings again not shown in this view, so as to draw upon themselves when inflated, thus maintaining the chamber demarcation and to avoid opening during the inflation phase.
  • the hook and loop portions alternate in their placement, on the left or right of the closure, from the top to the bottom of the wrap member.
  • a plurality of compressed air supply tubes 28 are secured to the compression wrap member in a manner to be discussed hereinafter.
  • the plurality of tubes further connects to a fluid supply, typically a tank of compressed air, not shown in this view.
  • the tubing is of a larger bore sufficient to initiate the flow more quickly and to assure the deflation cycle occurs more rapidly. Typically, the tubing inner diameter would be on the order of 0.5 inches(12.7mm).
  • the tubing can be reinforced in a known manner to ensure that it does not collapse during use.
  • the tubing for the NormaTec device has relatively small diameter openings which prolong the treatment cycle. For one chamber the cycle time for the NormaTec device is greater than 30 seconds. For a five chamber device the overall cycle time for the NormaTec device from the distal to proximal chambers would be a minimum of 150 seconds. Our invention is designed to greatly reduce these times.
  • Means for securing the two layers of garment section 22 together are depicted at the perimeter 30. This can be implemented using the heat sealing characteristics of the materials comprising the two layers as noted below or by using radio frequency(RF) techniques..
  • the typical length anticipated, 32 is on the order of 30 to 35 inches(76 to 89 cm) or tailored (custom) for a specific animal.
  • the width 34, it is anticipated, would be on the order of 28 inches(71cm).
  • the wrap member may be configured as tapered from a larger width at its proximal end to a smaller width at the hoof or distal end.
  • Garment section 22 includes top layer 36 and bottom layer 38.
  • Each layer, 36 and 38, are made of heat sealable (or RF) pack cloth material (for example Gortex), available from "Seattle Fabrics” of Seattle, Washington or similar supplier.
  • RF heat sealable pack cloth material
  • a series of 5 bladders, non porous 40, 42, 44, 46, and 48 are depicted, spaced along the length of layer 38.
  • the methodology of the invention allows for as few as three bladders. However, the practicalities of the device's application, especially with equines, warrant, no less than a four bladder configuration, and typically one with five bladders as depicted in Fig. 9 .
  • a higher number of individual bladders is possible as dictated by circumstances and the limitations of manufacture.
  • a higher number of bladders may provide a degree of redundancy in case of an unknown bladder failure during use.
  • the bladders overlap a respective, adjacent bladder. This overlap is approximately 1/3. So, bladder 42 overlaps bladder 40; bladder 44 overlaps bladder 42; bladder 46 overlaps bladder 44; and bladder 48 overlaps bladder 46.
  • the topside surface of layer 36 as seen in Fig. 2 may include a method of fastening(lengthwise VELCRO brand hook and eye strips are shown) a removable and reusable lining 37 such as a soft KODEL, or similar market type, fleece or sheep skin lining (not shown). This top side surface will be immediately adjacent the horse's skin. Thus the softer lining will minimize the discomfort, absorb perspiration, and decrease friction of cycling associated with the wrap member in place.
  • the bladders are made of heat, RF, or similar technology, sealable, Oxford nylon fabric also available from "Seattle Fabric” of Seattle, Washington or similar supplier.
  • Figure 2A is a perspective view of a typical bladder, such as 48, disposed above bottom layer 38 of garment section 32.
  • layer 38 is heat, RF, or similar technology sealable pack cloth material.
  • VELCRO or similar supplier pads 50 and 52 a total of 10 for a 5 bladder configuration
  • a VELCRO or similar supplier disc 54 a total of 5, again, for a 5 bladder configuration
  • a hole 56 is formed in both the layer 38 and VELCRO or similar supplier disc 54 to provide access for a fitting disposed on the bladder and which will be discussed hereinafter.
  • FIG 3 depicts the underside of a typical bladder as shown in Figure 2A .
  • Each bladder is seen to include corresponding VELCRO or similar supplier pads 58 and 60 and VELCRO or similar supplier disc 62. These are positioned and complement the corresponding pads disposed on layer 38 and discussed above with respect to Figure 2A .
  • FIG. 4 shows in section, the construction of a typical bladder such as 48.
  • a bladder includes layer(s) 64 and 66 which, again, is heat sealable Oxford or similar market supplier material available from "Seattle Fabrics".
  • the layers 64 and 66 are heat sealed along perimeter edge 68 to provide a sealed volume 69 interior to the inside surfaces of layers 64 and 66.
  • a brass (or similarly stiff product) crescent-shaped backer plate 70 is disposed in the volume 69 and bonded to the underside surface 72 of layer 64.
  • the complementing VELCRO or similar supplier disc 62 is likewise bonded to the outside surface 74 of layer 64.
  • Secured to the backer plate 70 is a brass (or similarly stiff product) right angle bulkhead fitting which includes a barbed end 78. The barbed end 78 is secured to a corresponding tube of the grouping 28.
  • each bladder may be further secured to layer 38 by heat tacking at different points, along the perimeter edge 68, to the layer 38. This will prevent the bladder from twisting inside the enclosure formed by layers 36 and 38.
  • FIG. 5 shown in partial, transverse cross-sectional view is a horse's hoof.
  • Relevant parts of the hoof for purposes of this description include the digital cushion area 80 which comprise a frog segment 82 and the bulbar area 84.
  • the phalanx associated with the laminitis condition, the distal phalanx or P3, is identified by reference numeral 86.
  • Secured to the under surface of the distal phalanx is the deep flexor tendon 88.
  • Extensor tendon 90 is connected to the forward surface of P3.
  • Covering the upper surface of the distal phalanx is an area known as the laminar corium 92.
  • the corium consists of a dense matrix of tough, connective tissue containing blood vessels and nerves.
  • the frog segment 82 is somewhat of a heart-shaped structure that extends forward across about two-thirds of the sole. At the back it merges with the heel and the bulbar area of the digital cushion. Of importance to the present invention is the fact that the frog acts like a pump to move the blood back to the heart - a great distance from the relatively thin leg to the main organ of the circulatory system.
  • the frog is anatomically analogous to the human finger tip.
  • the wall is anatomically analogous to the finger or toenail of a human.
  • Fig. 6 shows the compression wrap member portion 20 of the invention in place on the horse's or animal's limb.
  • the VELCRO or similar supplier straps 26 with D-rings allow for the draw down of the wrap in an alternating way. For example, the strap on the chamber 103 immediately above the hoof, is drawn to the left as viewed in Fig.6 ; while the immediately adjacent strap above is drawn to the right, and so forth up the leg.
  • the straps 26 are generally positioned at the center of a respective chamber.
  • the D-ring forces the VELCRO or similar supplier strap to draw upon itself when inflation occurs so as to preclude the release of the strap and thus the opening of the wrap member. (See Fig. 6A ).
  • VELCRO or similar supplier straps, or equivalent releasably securing means allows for the almost immediate removal of the wrap member from the horse's leg. This is important in that a horse is a fidgety animal and is disturbed at the smallest upset. The ability to unravel the wrap member relatively quickly assures that the horse does not become entangled in the compression wrap member and tubing which might create the possibility of further serious injury.
  • Fig. 6B depicts another arrangement for releasably securing the straps 26.
  • a double D ring is shown and the method of cinching the strap.
  • the end of the strap can include a Velcro portion which engages a complementing portion to keep the end from flapping. This can be used instead of the single D-ring Velcro arrangement of Fig. 6A ; or in addition to the Fig. 6A arrangement if a finer adjustment in tying down a particular chamber(s) is needed, especially when the therapeutic cycling is underway.
  • the inflatable bladders are within the garment which is in contact and surround completely the horse's or animal's limb.
  • Tubing 28 is dressed along the length of the wrap member and is directed in a safe manner away from the horse to the pressure source and system control means (see Fig.10 ),
  • the hoof covering segment 24 is also shown in place and its interrelationship or interaction with the hoof is better understood from viewing Figures 7 and 8 .
  • the wrap member is shown secured in place by the tightening down the respective VELCRO or similar supplier straps 26.
  • Hoof covering segment 24 is similarly secured through its VELCRO or similar supplier connection 104.
  • the hoof covering segment or boot 24 serves multiple purposes. The de-lamination of the lamellae between the inner surface of the hoof wall and the digital phalanx results in the hoof starting to splay outward such that the sole becomes flatter. With the boot in place the wall integrity of the hoof is maintained and is protected against splaying while at the same time keeping the painful sole off of hard surfaces.
  • the boot is made in a similar manner to the shoe worn by horses known as the "Sport Boot” by CAVALLO® or similar supplier.
  • the soles of the boot 106 have a tread surface and include a rounded anterior front segment 108.
  • the treads provide substantial traction for the animal.
  • the sole treads can be constructed of recycled tires as a cost efficiency factor.
  • the boot includes an upper leather portion 110 which can be lined with fleece or a sheep skin type lining; and includes a nylon cover to minimize dirt and stone abrasion.
  • Bladder 40 includes a tongue-shaped segment 112 (see particularly Fig. 2 ).
  • the tongue-shaped segment 112 When the wrap member is in use, the tongue-shaped segment 112 is disposed in the boot and is of sufficient length to cover the sole and frog areas of the horse's hoof, as well as engage the bulbar portion of the digital cushion 80. This segment stimulates the horse's circulatory system in the hoof area in accordance with the principles of the invention.
  • As part of the inflation/deflation cycle of the present invention see discussion for Fig. 9 below, it will assist the frog segment in pumping blood from the distal end of the limb to the proximal end.
  • An inner sole pad 114 made of a strong density, non-memory foam or silicone pad is interposed between the upper surface of bladder segment 112 and the frog-sole area of the animal's hoof.
  • the pad is slightly elevated (thicker) in its central posterior area.
  • segment 112 When the bladder system is pressurized, segment 112 will urge the silicone pad upward against the resistance of the frog segment.
  • the silicone gel will have enough give to deform laterally and, when released, enough memory to resume its normal shape.
  • the boot with the inner sole pad 114 can remain in place on the hoof when the compression wrap member is removed.
  • the upper margin of the boot will have 2 or 3 "V" shaped darts lined with heavy duty elastic attached to either side of the V cut and spanning the latter.
  • This provides a simple mechanism for keeping the boot on the hoof in addition to the VELCRO straps or similar market supplier.
  • the edge of the boot can be rolled and or padded to minimize irritation to the coronary band and other immediately adjacent segments of the horse's hoof.
  • the boot portion of the invention will accomplish or assist in one or more of the following.
  • the efficiency of the boot will provide horse owners with a more rapid healing process, a decrease in the recuperation and down time and most importantly, the reduction of pain for the animal and overall remission of the disease more quickly. Expanding its usefulness we can include stone bruises, thrush, vascular and foot pain in general.
  • a controllable pressure source includes a pump 116 connected through an appropriately sized expansion tank 118 to a known form of a valve control block 120.
  • the expansion tank maintains a suitably stable pressure head at the input to the valve control block so that the constant pressures, P H and P L can be developed and maintained throughout the therapeutic procedure.
  • the valve control block 120 includes a suitable valve package and pressure reducers so as to inflate, deflate and otherwise control the flow and magnitude of the pressurized fluid to and from the respective bladders positioned in the compression wrap member.
  • a suitably programmed CPU 122 is accessed and directed, as needed, by a user through a suitable input device 124, such as a keyboard. The CPU will direct the valve control block to supply appropriate pressure levels for given time intervals, also controlled in number and length by the controllable pressure source, as may be guided by a therapy plan, such as reflected by the various Figures, 9 through 9J .
  • the number of bladders for purposes of this embodiment are five; and, again, they can vary from a minimum of three to a higher number as dictated by the practicalities of the application and the needs of a particular circumstance. The higher the number, the more effective the control and overall efficacy.
  • the other variables that change will be the number of fill intervals which are directly related to the number of chambers, i.e. number of chambers equal the number of fill intervals; and the number of ramp-up intervals where the number of intervals will equal the number of chambers minus the number of P L in a complete wave, minus one
  • each chamber is filled with a low pressure P L .
  • P L a low pressure
  • P L a low pressure
  • Chamber number 1 is maintained at P L and the valve to chamber 2 is opened and it, too, reaches P L
  • Each of the remaining chambers over the course of time intervals 1 through 5, are pressurized at the low pressure level, P L
  • P L After all chambers, 1 through 5, have reached the low pressure status, the fill cycle is complete.
  • the number of time intervals to reach the "fill" point is equal to the number of chambers.
  • the ramp-up cycle is initiated.
  • the purpose of the ramp-up cycle is to transition the system from the "quiet" fill cycle to the dynamic, repetitive cycle. This is done so as to achieve less of a perceived change, by the animal, from the fill cycle to the dynamics that are to occur during the rigorous therapeutic or repetitive cycle phase.
  • This ramp-up cycle, or even the fill cycle under certain circumstances may not even be used. So, for example, after the animal has experienced the treatment over a period of days, it may be more accepting of it. This perhaps will allow the immediate application of the therapeutic, repetitive cycle phase during the therapy session.
  • the number of time intervals required to "ramp-up" to the repetitive, therapeutic stage are established by the number of chambers and the characteristics of the pressure wave that is to be established for the repetitive cycle (a "pressure wave” is defined as a single combination or set of adjacent P H pressurized chambers, taken as a single unit for this determination, and the number of adjacent P L inflated chambers, counted individually, again when used to determine the length of the ramp-up cycle).
  • the number of time intervals to achieve the ramp-up cycle is the sum of the number of chambers at P L in the wave pattern, plus 1(for the P H set) subtracted from the total number of chambers for a given wrap garment.
  • the pressure wave in Fig. 9 for a five chamber device comprises two adjacent chambers pressurized at P H (counts as one) and one chamber pressurized at P L . According to the above this results in a ramp-up cycle of three (five minus (one plus one)) time intervals before the system enters the repetitive cycle phase.
  • pressure to chamber 1 is now increased to a higher, therapeutic pressure P H.
  • P H is in the range of 0 to 200 mm Hg, and within a preferred range of 10 to 60 mm Hg, but always in excess of P L . Chambers 2 through 5 remain at the low pressure status.
  • chamber number 2 is now inflated with the higher pressure.
  • chamber 1 is maintained at the higher pressure so as to eliminate back flow possibilities from the physical area of the horse's leg engaged by bladder number 2 into the area covered by bladder number 1, the hoof area.
  • the controlled pressure source continues to direct the pressurization of chamber number 2 at P H , and, although not readily apparent from the drawings, retains pressurization of chamber number 1 at PH until pressurization of number 3 is achieved, whereupon pressurization of chamber number 1 is reduced to P L .
  • the system as adapted does not permit back flow from a higher number chamber to a lower numbered one, i.e a more distal one.
  • the results achieved by the apparatus and method of the present invention are significantly advantageous.
  • the programmed controller 120 will return the wrap member, and particularly the bladders, to the interval and pressure just prior to the ramp-up cycle. In the embodiment illustrated in Fig. 9 , this would be time interval number 5, where all the chambers are in their low pressure status, P L (of course, if the wrap member is to be removed, the valve control block 120 can be directed to release all pressurized fluid to the respective chambers).
  • the controller would direct the restart of the ramp-up cycle, in a manner similar to what occurs at time interval number 6.
  • the pressure levels and length of time intervals (5 sec to 30 sec preferred for the therapeutic, repetitive range) are largely a variable based in part on the condition of the animal.
  • the approach described allows the animal to get acclimated to the device by gradually increasing pressure and/or adjusting the time interval, dependent on condition. All are programmable in the controller by the CPU as inputted to by a user. It is known how to vary these pressure levels and time intervals in related technology so as to effect the ramp up and repetitive cycles as depicted in Figure 9 .
