Description

Technical Field

[0001] The present invention relates to the technical field of walking assistance devices, and particularly relates to an assistor for elderly sarcopenia patients and a using method thereof. Background Art

[0002] With the acceleration of the global aging process, the health problems of the elderly population have become increasingly prominent. As an age-related geriatric syndrome characterized by reduced muscle mass, decreased muscle strength, and / or physical dysfunction, sarcopenia has become one of the common health problems among the elderly. Sarcopenia not only leads to low physical activity ability of patients, but also significantly increases the risk of adverse outcomes such as frailty, falls, disability, and even death, imposing a heavy disease burden. For elderly sarcopenia patients, the attenuation of lower limb skeletal muscle seriously affects the normal activities of their muscles, resulting in problems such as difficulty standing and slow walking. In daily activities such as going up and down stairs, due to insufficient leg muscle strength, patients often need to rely on external forces or handrails to complete, which has a serious impact on their quality of life.

[0003] Currently, some assistive devices for elderly sarcopenia patients have emerged. However, these devices all have some problems in actual use. For example, the existing devices mainly focus on improving the stability of the patient's leg muscles and lack the assisting effect during the patient's walking. At the same time, the existing devices lack the protection design for the patient's ankles during walking, which may cause the patient to sprain their ankles, resulting in relatively weak reliability.

[0004] Existing assistive devices, such as a knee joint exoskeleton for walking assistance provided in the publication number CN118948581A, include an exoskeleton framework, which includes a thigh component and a calf component; an ankle joint subsystem, which is connected to the exoskeleton framework, and the ankle joint subsystem provides passive assistance for the user's ankle joint during walking; a knee joint rotation assistance subsystem, through which the thigh component and the calf component are connected; a load distribution optimization subsystem, which is connected to the exoskeleton framework by binding; the knee joint rotation assistance subsystem includes a standing state and an active state. When the knee joint rotation assistance subsystem is in the standing state, the drive subsystem locks the exoskeleton framework; when the knee joint rotation assistance subsystem is in the active state, the calf component can rotate relative to the thigh component. However, since each structure of this device is mainly controlled by structures such as electric push rods and motors, in actual use, due to the easy damage or failure of the electric push rods and motors, the overall reliability of the device is relatively weak. Moreover, this device also lacks a protection structure for the patient's ankle joint during walking, so its functions are relatively single. In addition, the overall structure of this application is relatively complex, and it is inconvenient to repair and replace when a failure occurs. Summary of the Invention

[0005] In view of the above problems, the present invention aims to provide an assistor for elderly patients with sarcopenia. By designing a linkage assist component, artificial muscles are provided on the thigh support plate and the calf support plate, and an inflatable component capable of automatic reset is provided on the foot support plate. By stepping on the inflatable component to inflate the artificial muscles, an assisting effect is provided for the legs, and when lifting the legs, the reset of the inflatable component provides assistance for the lifting of the patient's feet, thereby providing an assisting effect when the elderly patients with sarcopenia walk. By designing a bottom protection component, a suction cup structure is designed at the bottom of the foot support plate, and an anti-slip plate that can be driven to extend by the suction cup structure is combined to improve the stability when the patient walks on the ground, and the ankle protection air cushions on both sides are combined to provide protection for the patient's ankles, having the advantages of strong assisting effect, good stability, high reliability, strong flexibility and simple structure.

[0006] The main idea of the technical solution adopted by the present invention: Design a linkage assist component. By providing a thigh support plate and a calf support plate on the thigh fixing ring and the calf fixing ring, and fixing inflatable artificial muscles on the two support plates, and providing an inflatable component communicated with the artificial muscles on the foot support plate, to provide an assisting effect for the legs or feet by stepping on; Design a bottom protection component. By providing a suction cup under the foot support plate and providing a support rod at the edge of the suction cup, when stepping on the foot support plate, the suction cup is adsorbed to the ground, and the anti-slip plate located in the foot support plate is pushed out by the support rod to improve the stability when the patient walks, and at the same time, the ankle protection air cushions on both sides are combined to provide a protection effect on both sides of the ankle to prevent the patient from spraining the ankle when walking.

[0007] To achieve the above object, the technical solution adopted by the present invention is as follows: An assistor for elderly patients with sarcopenia, including a thigh fixing ring, a calf fixing ring and a foot support plate that are rotatably connected to each other, and further including a linkage assist component for providing assistance to elderly patients with sarcopenia and a bottom protection component for improving the walking stability of the patient.

[0008] The linkage assist component includes a leg assist member, and the leg assist member includes a fixing plate fixed to the thigh fixing ring and the calf fixing ring, and an artificial muscle is snap-fixed on the fixing plate.

[0009] Based on the above technical solution, further, it further includes an inflation member for inflating the artificial muscle. The inflation member includes an inflation airbag fixed above the foot support plate. The inflation airbag is communicated with the artificial muscle. A airbag return spring is further arranged in the inflation airbag. A plurality of air inlet through holes capable of inflating the inflation airbag are formed in the foot support plate. When the inflation airbag is stepped on, it can inflate the artificial muscle to provide assistance to the patient's leg. When the patient lifts the foot, the inflation airbag resets under the action of the airbag return spring, thereby providing assistance to the patient's foot.

[0010] The bottom protection component includes a plurality of suction cups fixed below the foot support plate. A plurality of anti-slip plates are slidably arranged on the front and rear sides of the foot support plate. A plurality of support rods are arranged at the edge of the suction cup. Adjustment holes for the support rods to pass through are formed in the anti-slip plates. A guide groove for guiding the sliding of the support rods is further formed in the foot support plate. When the suction cup is pressed down by the foot support plate, it can adsorb the ground. At the same time, the support rods penetrate into the adjustment holes on the anti-slip plates and slide towards the edge of the foot support plate through the guide groove, pushing the anti-slip plates out along the foot support plate to improve the stability when the patient steps on the ground.

[0011] Based on the above technical solution, further, it further includes an ankle protection part. The ankle protection part includes ankle protection air cushions fixed on both sides above the foot support plate. The ankle protection air cushions are communicated with the inflation airbag in the inflation member. When the inflation airbag is squeezed, it can inflate part of the air into the ankle protection air cushions to provide a protection effect on both sides of the patient's ankle.

[0012] The thigh fixing ring and the calf fixing ring are also rotatably connected through an adjustable connection component. The adjustable connection component includes an adjustment rod. The upper end and the lower end of the adjustment rod are rotatably connected with a first connecting rod respectively. A second connecting rod is slidably connected to the first connecting rod. The second connecting rod is fixedly connected to the thigh fixing ring or the calf fixing ring respectively.

[0013] Based on the above technical solution, further, it further includes an adjustment member for adjusting the overall length of the first connecting rod and the second connecting rod. The adjustment member includes a pressing block rotatably arranged at one end of the first connecting rod away from the adjustment rod. A limiting rod for clamping the second connecting rod is fixed at one end of the pressing block. A plurality of positioning holes capable of allowing the limiting rod to penetrate are evenly distributed along a straight line on the second connecting rod. A pressing block return spring is arranged between the end of the pressing block away from the limiting rod and the first connecting rod. When the pressing block is pressed, it can pull out the limiting rod from the positioning hole to adjust the overall length of the first connecting rod and the second connecting rod. When the pressing of the pressing block stops, the pressing block resets under the action of the pressing block return spring, and the overall length of the first connecting rod and the second connecting rod is fixed by the limiting rod penetrating into the positioning hole.

[0014] Based on the above technical solution, further, a corrugated joint sleeve for cooperating with the bending of the patient's knee joint is also provided on the adjusting rod.

[0015] A usage method of a booster for elderly sarcopenia patients includes the following steps: S1. Wear the booster along the patient's lower limb. Adjust the adjustable connection component according to the lengths of the patient's thigh and calf. After the adjustment is completed, fix the thigh fixing ring, calf fixing ring, and foot support plate to the patient's thigh, calf, and foot respectively. S2. When the patient walks while wearing the booster, step on the inflatable component on the foot support plate to inflate the artificial muscles in the thigh and calf to provide a forward boosting effect on the legs. When the patient lifts the foot, the inflatable component resets and provides a boosting effect on the patient's sole. S3. When the patient steps on the foot support plate, inflate the ankle protection air cushions on both sides through the inflatable component to support and protect both sides of the ankle joint.

[0016] The beneficial effects of the present invention are as follows: 1. By designing the linkage boosting component, when the patient walks and steps on the inflatable airbag on the foot support plate, the artificial muscles in the thigh and calf are inflated to provide a boosting effect on the patient's legs. When the patient lifts the foot, the inflatable airbag is reset by the airbag return spring to provide a boosting effect on the patient's foot, thereby providing a boost to the patient's walking, making the present invention have the advantage of strong boosting effect.

[0017] 2. By designing the bottom protection component, the ground is adsorbed through the suction cups located below the foot support plate, and an anti-slip plate that can be pushed out by the suction cups is arranged in the foot support plate to improve the stability of the patient when walking.

[0018] 3. By designing the ankle protection part, through the inflation of the inflatable airbag, the ankle protection air cushion expands and bulges to protect and support both sides of the patient's ankle joint, preventing the patient from spraining the ankle when walking, and improving the functionality of the present invention.

[0019] 4. By designing the adjustable connection component, by adjusting the overall length of the first connecting rod and the second connecting rod, and through the adjusting member, the limiting rod on the pressing block of the first connecting rod penetrates into the positioning hole on the second connecting rod to fix the overall length of the first connecting rod and the second connecting rod, enabling the present invention to be adjusted according to the overall leg lengths of different patients and improving the flexibility.

[0020] 5. The overall structure of the present invention is simple, and the booster is driven by the air supply of the airbag as a whole. Compared with the prior art using structures such as motors or electric push rods, the present invention can avoid the possibility of faults in the electrical products themselves, thereby improving the overall reliability of the device, and at the same time having the advantage of low power consumption.

[0023] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of this application. Obviously, the described embodiments are some, but not all, of the embodiments of this application. Usually, the components of the embodiments of this application described and illustrated in the accompanying drawings here can be arranged and designed in various different configurations.

[0024] The inventors' research found that there are some problems in the actual use of existing auxiliary assist devices for elderly patients with sarcopenia. For example, existing devices only improve the walking stability of patients by fixing the leg muscles of patients, etc., lacking the assist effect during patients' walking; at the same time, existing devices lack a protection structure for the ankles during patients' walking, resulting in the situation that patients are prone to sprain their ankles during walking, and the reliability is poor; in addition, some existing devices use structures such as electric push rods or motors. Due to their large power consumption and easy failure and damage, the safety is poor, and there are also problems of single function and complex structure.

[0025] Based on the above findings, the present application proposes an assistive device for elderly patients with sarcopenia. By designing a linkage assist component, inflatable artificial muscles are provided on the thigh fixing ring and the calf fixing ring, combined with the inflatable airbag on the foot support plate. When the patient walks and steps on the inflatable airbag, it inflates the artificial muscles to provide assistance to the entire leg, and when lifting the foot, it provides an assisting effect on the foot through the reset function of the airbag. By designing the bottom protection component, suction cups are provided under the foot support plate to improve the adsorption effect on the ground during walking. At the same time, the anti-slip plate on the foot support plate is pushed out through the sliding action of multiple support rods on the suction cup to improve the stability of the patient during walking, and combined with the inflatable airbag to inflate the ankle protection air cushion to protect the ankle. It has the advantages of strong assisting effect, good stability, high reliability, strong flexibility and simple structure.

[0026] Referring to Figures 1-4 , the present application discloses an assistive device for elderly patients with sarcopenia, including a thigh fixing ring 1, a calf fixing ring 2 and a foot support plate 3. In some embodiments of the present invention, both the thigh fixing ring 1 and the calf fixing ring 2 are ring structures made of lightweight metals or plastics with relatively high strength. A support airbag 9 for improving the fixing effect with the patient's leg is also provided on the thigh fixing ring 1 and the calf fixing ring 2. At the same time, a fixing strap 8 for binding to the patient's leg is also provided on the thigh fixing ring 1 and the calf fixing ring 2.

[0027] In an embodiment of the present invention, the thigh fixing ring 1 and the calf fixing ring 2 are rotatably connected through an adjustable connection component 7, so that the assistive device can be adjusted according to the leg lengths of different patients, so as to fix the thigh fixing ring 1 and the calf fixing ring 2 to the patient's leg; Referring to Figure 5 , Figure 6 and Figure 7 , the adjustable connection component 7 includes adjusting rods 701 located on both sides of the patient's knee joint. The adjusting rods 701 are metal plate members with rotating shaft structures inserted at both ends. When the patient wears the assistive device and walks, the adjusting rods 701 can act as rotating members to rotate in cooperation with the bending of the patient's leg. First connecting rods 702 are rotatably connected to the rotating shafts at the upper and lower ends of the adjusting rods 701. A fixed ring-shaped connecting block 706 structure is provided on the first connecting rods 702, and thus a tight sliding connection is formed with the second connecting rods 703. That is, the overall length of the first connecting rods 702 and the second connecting rods 703 can be adjusted, but it can cooperate with the friction force with the ring-shaped connecting block and the adjusting member 704 below to maintain the stability of the relative connection; Meanwhile, one end of the second connecting rod 703 away from the second connecting rod 702 is fixed to the thigh fixing ring 1 or the calf fixing ring 2 by means of welding or bolt connection. When the patient wears this power assist device and walks, the thigh and the calf bend relative to each other, and the first connecting rod 702 and the second connecting rod 703 can be driven by the thigh fixing ring 1 and the calf fixing ring 2 to rotate relative to the adjusting rod 701. At the same time, a corrugated joint sleeve 705 is fixed to the adjusting rod 701 by means of welding or clamping. The corrugated joint sleeve 705 is made of soft material and can keep in contact with the front and back sides of the knee joint when the patient walks, so as to protect the patient's knee joint. An adjusting member 704 is further provided at the sliding connection between the first connecting rod 702 and the second connecting rod 703. In some embodiments, the adjusting member 704 includes a pressing block 7041 which is rotatably fixed to one end of the first connecting rod 702 close to the second connecting rod 703 (i.e., away from the adjusting rod 701) by means of a rotating shaft structure provided in the middle. A limiting rod 7042 is fixed to one end of the pressing block 7041 by means of welding or threaded connection. At the same time, a plurality of positioning holes 7043 are formed in the second connecting rod 703. A pressing block return spring 7044 is fixed to the pressing block 7041 at the end away from the limiting rod 7042, and the other end of the pressing block return spring 7044 is fixed to the rod body of the first connecting rod 702 by means of welding or bolt connection. It should be noted that in an embodiment of the present invention, the adjusting member 704 located below the adjusting rod 701 and close to the calf fixing ring 2 has the opposite setting direction to the above content, that is, the pressing block 7041 is fixed to the second connecting rod 703 here, and the positioning hole 7043 is formed in the first connecting rod 702 here. That is, in this application, the rod directly rotatably connected to the adjusting rod 701 through a rotating shaft is defined as the first connecting rod 702. Refer to Figure 9 , when it is necessary to adjust the length between the first connecting rod 702 and the second connecting rod 703, the end of the pressing block 7041 away from the limiting rod 7042 can be pressed down to pull out the limiting rod 7042 from the positioning hole 7043, so as to adjust the first connecting rod 702 and the second connecting rod 703. After the adjustment is completed, the pressing block 7041 is released, and it is reset under the elastic force of the pressing block return spring 7044, so that the limiting rod 7042 is re-engaged in the positioning hole 7043 to re-fix the relative length between the first connecting rod 702 and the second connecting rod 703. In addition, third connecting rods 7045 are fixed to both sides of the bottom of the calf fixing ring 2 by means of welding or bolt connection. The bottoms of the two third connecting rods 7045 are provided with a foot support plate 3 by inserting a rotating shaft. Multiple groove structures for improving the anti-slip effect are formed at the bottom of the foot support plate 3. Chutes for conveniently placing anti-slip plates 502 are formed at the front end and the rear end of the foot support plate 3. Multiple fixing straps 8 for fixing the patient's feet are further provided on the foot support plate 3. The fixing straps 8 have a certain elasticity and remain in a taut state when wearing this booster, and can cooperate with the patient's feet for a certain degree of contraction.

[0028] In some embodiments, this booster further includes a linkage boosting component 4 for providing a boosting effect for elderly sarcopenia patients when walking. The linkage boosting component 4 includes a leg boosting member 401. The leg boosting member 401 includes two fixing plates 4011 vertically fixed to the thigh fixing ring 1 and the calf fixing ring 2. An interconnected artificial muscle 4012 is fixed to the fixing plates 4011 by means of clamping or bonding. In this embodiment, the artificial muscle 4012 is an existing inflatable artificial muscle product, which can be inflated into its interior through an inflating component 402, thereby squeezing the patient's leg muscles, assisting the leg muscles to contract, and at the same time providing a forward thrust to the patient's legs to boost the legs when the patient walks. The linkage boosting component 4 further includes an inflating component 402. The inflating component 402 includes an inflatable airbag 4021 fixed to the upper surface of the foot support plate 3. The inflatable airbag 4021 is close to the side of the patient's back when wearing this booster and is connected to the artificial muscle 4012 close to the calf by inserting an air delivery pipe 6. When the patient walks and steps on the ground through the foot support plate 3, the air in the inflatable airbag 4021 can be squeezed into the artificial muscle 4012 by the patient's own body weight to boost the legs. Meanwhile, an airbag return spring 4022 is disposed inside the inflatable airbag 4021. Specifically, at the four air intake through holes 4023 on the inner bottom surface of the inflatable airbag 4021, the airbag return spring 4022 is fixed by welding or bonding. The top of the airbag return spring 4022 is fixed with a blocking block 4024. The top of the blocking block 4024 is fixed to the top of the inflatable airbag 4021 by bonding or the like. When the patient steps on the inflatable airbag 4021, the blocking block 4024 can just block the air intake through holes 4023. At this time, it can be regarded that the air pressure in the inflatable airbag 4021 and the artificial muscle 4012 is in a balanced state. When the patient lifts the foot, the inflatable airbag 4021 expands and returns under the action of the airbag return spring 4022 and the air pressure, and can provide a certain boosting effect on the patient's sole. Through the repeated gas exchange between the inflatable airbag 4021 and the artificial muscle 4012, the inflatable airbag 4021 provides assistance when the patient's leg is in different states.

[0029] Refer to Figure 8 , and Figures 10-13 , a bottom protection assembly 5 is further provided below the foot support plate 3. The bottom protection assembly 5 includes a plurality of suction cups 501 disposed below the bottom of the foot support plate 3. In some embodiments, the number of suction cups 501 is the same as the number of air intake through holes 4023 formed on the foot support plate 3, that is, four in total, and they are distributed on the front and rear sides of the foot support plate 3 in groups of two. The suction cups 501 can be fixed below the foot support plate 3 by passing through the top rod by bonding or threaded connection. A hole is formed in the middle of the suction cup 501, that is, the suction cup 501 does not affect the normal gas exchange of the inflatable airbag 4021. When the patient walks, the adsorption effect of the bottom suction cups 501 on the ground can provide a stable support effect for the patient. In some embodiments, three support rods 503 are fixed at the upper edge of the suction cup 501. Meanwhile, anti-slip plates 502 are slidably disposed at the front and rear ends of the foot support plate 3. A guide groove 505 for the support rod 503 to penetrate is formed at the bottom of the foot support plate 3. An adjustment hole 504 for one of the support rods 503 to penetrate is formed on the anti-slip plate 502 opposite to the guide groove 505. Normally, the top end of the support rod 503 extends into the lower section of the guide groove 505 and the adjustment hole 504 of the anti-slip plate 502 and is completely attached to one side of the guide groove 505. When the foot support plate 3 presses down on the suction cup 501, the support rod 503 can be pressed to move upward along the guide groove 505 and penetrate through the adjustment hole 504 on the anti-slip plate 502. When the support rod 503 continues to move upward, it can be squeezed by the inclined section of the upper section of the guide groove 505 and then tilted toward the edge of the foot support plate 3 to drive the anti-slip plate 502 to be pushed out of the foot support plate 3 as an extension of the whole foot support plate 3, thereby achieving a certain anti-slip effect. It should be noted that at this time, due to the bending of the support rod 503, a certain deformation can be driven at the edge of the suction cup 501, thereby preventing the suction cup 501 from being completely adsorbed to the smooth ground and hindering the normal walking of the patient; in addition, the anti-slip plates 502 located on the front or rear side are of a symmetrical structure, and the middle part thereof is also elastically connected through a structure similar to the corrugated joint sleeve 705. Through this structure and the limiting effect of the support rods 503 on both sides, the anti-slip plates 502 can be prevented from sliding out of the foot support plate 3. When the patient lifts the foot, the suction cup 501 restores the deformation under its own elastic force, drives the support rod 503 and the anti-slip plate 502 to reset, and pushes out the anti-slip plate 502 when the patient steps on the ground next time.

[0030] Refer to Figure 14 and Figure 15 , in some embodiments, an ankle protection part 506 is further provided above the foot support plate 3. The ankle protection part 506 includes two ankle protection air cushions 5061 fixed to the two third connecting rods 7045 on both sides by bonding or the like and close to the midline of the patient's foot. When the patient wears this booster and uses the fixing belt 8 to fix the foot to the foot support plate 3, the patient's ankle can just fit with the ankle protection air cushion 5061. The ankle protection air cushion 5061 is communicated with the inflation air bag 4021 through the air supply pipe 6. Then when the patient stands or steps on the foot support plate 3 during walking, the inflation air bag 4021 can be used to inflate the ankle protection air cushion 5061, covering both sides of the patient's ankle to prevent the ankle from bending to both sides of the patient's body and causing the patient to sprain the ankle, which is beneficial to improving the overall reliability of the present invention; It should be noted that when the patient has a balance problem during walking, at this time, due to the uneven pressure of the foot on the inflation air bag 4021, the amount of gas filled in the ankle protection air cushions 5061 on both sides is also different, that is, the inflation amount of the ankle protection air cushion 5061 on the side close to the patient's body tilt is greater than that on the other side. That is, the ankle can be supported by the ankle protection air cushion 5061 on this side to prevent the ankle from bending towards this side. That is to say, the ankle protection part 506 can dynamically adjust according to the uneven pressure generated by the patient's foot on the inflation air bag 4021, and then protect the ankle; in addition, the overall height of the ankle protection air cushion 5061 can be appropriately increased according to the actual situation to ensure that the ankle protection air cushion 5061 still covers the patient's ankle after the inflation air bag 4021 is squeezed.

[0031] A method for using a booster for elderly patients with sarcopenia, comprising the following steps: S1. Wear a single or a pair of the present boosters along the patient's lower limb. Adjust the adjustable connection component 7 according to the lengths of the patient's thigh and calf. After the adjustment is completed, use the fixing strap 8 to fix the thigh fixing ring 1, the calf fixing ring 2, and the foot support plate 3 to the patient's thigh, calf, and foot respectively. S2. When the patient wears the booster and walks, step on the inflatable component 402 on the foot support plate 3, and inflate the artificial muscle 4012 through the inflatable airbag 4021 to provide a forward boosting effect on the leg. When the patient lifts the foot, the inflatable component 402 resets and provides a boosting effect on the patient's sole. S3. When the patient steps on the foot support plate 3, inflate the ankle protection air cushions 5061 on both sides through the inflatable component 402 to support and protect both sides of the ankle joint. Actual application cases

[0032] For elderly patients suffering from sarcopenia, due to the progressive degenerative changes in the lower limb muscle groups, it is difficult to have the ability to walk independently without external assistance. At this time, according to the actual situation of the patient's legs, one or a pair of the present boosters can be selected. After adjusting the overall height of the device through the adjustable connection component 7, use the fixing strap 8 to fix it to the patient's leg. When the patient wears the present booster and walks, when the patient is in a standing state or steps on the ground with one foot while walking, the inflatable airbag 4021 on the foot support plate 3 is squeezed by the patient's own weight to inflate the artificial muscle 4012 to assist the leg muscles; when the patient lifts the foot, the inflatable airbag 4021 resets under the action of the return spring and the internal air pressure to provide an upward boosting effect on the patient's sole. When the patient walks and steps on the foot support plate 3, adsorb the ground through the suction cup 501 at the bottom and combine with the anti-slip plate 502 pushed out to improve the stability when stepping on the ground. At the same time, inflate the ankle protection air cushion 5061 through the inflatable airbag 4021 to support and protect the patient's ankle joint to prevent the patient from spraining the ankle when walking.

[0033] The above shows and describes the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments. What is described in the above embodiments and the specification only illustrates the principles of the present invention. Without departing from the spirit and scope of the present invention, the present invention will have various changes and improvements, and these changes and improvements all fall within the scope of the present invention claimed. The scope of protection claimed by the present invention is defined by the appended claims and their equivalents.
