Description

Technical Field

[0001] This invention relates to the field of medical devices, and in particular to a rehabilitation training device for patients with diabetic sarcopenia. Background Technology

[0002] Diabetic sarcopenia is a comorbidity of type 2 diabetes and sarcopenia. Patients experience decreased muscle mass and strength, along with insulin resistance and impaired glycemic regulation. Clinical studies have shown that the rate of muscle loss in the lower limbs is particularly significant in patients with diabetic sarcopenia. This not only leads to difficulty walking and decreased balance, but also increases their risk of falls and hip fractures by more than three times compared to healthy individuals of the same age. Resistance training is currently recognized as an effective intervention to slow muscle loss and improve insulin sensitivity.

[0003] Currently, there are many rehabilitation training devices for diabetic patients, such as those using a seat and foot pedals with adjustable hydraulic dampers, and those using elastic bands with wristbands or ankle straps for resistance training. However, these existing devices have the following problems in actual clinical applications: First, regarding applicable scenarios, all of the aforementioned devices require patients to be in a sitting or standing position for training. For diabetic sarcopenia patients who are bedridden for extended periods due to conditions such as diabetic foot ulcers, heart failure, postoperative immobilization, or severe myasthenia gravis, their inability to transition to a sitting or standing position independently prevents them from using the devices during the critical bed rest rehabilitation period. These patients experience accelerated muscle loss in their lower limbs during bed rest, and by the time their condition improves and they can get out of bed, their muscle strength has severely deteriorated, causing them to miss the optimal window for early rehabilitation intervention.

[0004] Secondly, regarding safety, patients with diabetic sarcopenia face unique physiological risks during exercise training. Due to their impaired blood glucose regulation, they are highly susceptible to hypoglycemia or stress-induced hyperglycemia during exercise. Existing devices can only provide fixed mechanical resistance and cannot sense the patient's blood glucose status, let alone adjust the training load according to blood glucose changes. Once a patient experiences hypoglycemia during training, their muscle control ability declines sharply, while the device continues to operate at the preset resistance, easily leading to muscle strain, joint injury, or even fainting due to insufficient physical strength to control the range of motion. This problem is particularly prominent in bedridden patients because their muscle reserve is extremely low, and their tolerance window for training load is very narrow.

[0005] Third, regarding training effectiveness, one of the core pathological characteristics of diabetic sarcopenia patients is poor eccentric contraction control. Studies have shown that targeted eccentric resistance training has unique value in stimulating muscle protein synthesis and improving muscle strength. However, existing devices mostly provide resistance in a concentric-eccentric symmetrical pattern, which cannot differentiate the load according to the type of muscle contraction, resulting in poor eccentric training effects.

[0006] In summary, how to design a rehabilitation training device that is suitable for bedridden patients, can adjust the training load in real time according to the patient's physiological state, and can effectively implement eccentric training is a technical problem that urgently needs to be solved in this field. Summary of the Invention

[0007] The present invention aims to at least solve one of the technical problems existing in the prior art. Therefore, one object of the present invention is to provide a rehabilitation training device for patients with diabetic sarcopenia.

[0008] The technical solution of the present invention is as follows: a rehabilitation training device for diabetic sarcopenia patients, characterized in that it includes: a fixing module, a training module, a blood glucose monitoring module, and a controller; The fixing module includes a fixing frame and a first fixing member disposed on the fixing frame. The fixing frame is laterally detachable at the foot of the bed via the first fixing member. The training module is movable left and right and is located on the front side of the fixed frame. There are two training modules, one on the left and one on the right, arranged side by side. The fixed frame is equipped with a spacing adjustment mechanism, which is connected to the two training modules. The spacing adjustment mechanism is used to drive the two training modules to move towards each other or away from each other to adjust the spacing between them. The training module includes a base, a guide slide, a foot pedal slider, a buffer assembly, an angle adjustment mechanism, and a resistance adjustment mechanism. The base is connected to the spacing adjustment mechanism. The guide slide is positioned above the base, and its front end is hinged to the base. The base has an angle adjustment mechanism for driving the guide slide to rotate and adjust its tilt angle. The foot pedal slider is slidably mounted on the guide slide. The foot pedal slider has a second fixing component for securing the patient's foot. The front and rear ends of the guide slide have buffer assemblies for cushioning the impact of the foot pedal slider. The guide slide has a resistance adjustment mechanism for adjusting the resistance of the foot pedal slider as it slides along the guide slide. The blood glucose monitoring module includes an abdominal binder and a blood glucose sensor. The abdominal binder is mounted on the mounting bracket and is used to wrap around the patient's abdomen. The blood glucose sensor is mounted on the abdominal binder. The spacing adjustment mechanism, angle adjustment mechanism, resistance adjustment mechanism, and blood glucose sensor are respectively connected to the controller. The controller is configured to automatically adjust the resistance of the resistance adjustment mechanism according to the parameters of the blood glucose sensor and apply different resistance values ​​in different movement directions of the foot pedal slider.

[0009] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. High adaptability to bedridden scenarios: By detachably installing the fixed module at the end of the hospital bed, and in conjunction with the guide slide and foot pedal slider structure, patients can perform lower limb resistance training in a supine position. This solves the limitation of existing devices that are only suitable for sitting or standing positions, and fills the gap in rehabilitation training devices for bedridden diabetic sarcopenia patients.

[0010] 2. Strong individualized rehabilitation capability: By setting up dual training modules with adjustable spacing, a guide slide with electrically adjustable tilt angle, and an electromagnetic resistance adjustment mechanism, the training parameters can be flexibly adjusted according to the patient's body type, muscle strength level, and rehabilitation stage, realizing full-cycle progressive rehabilitation training from the initial bed rest to the recovery of walking. One device covers multiple rehabilitation stages.

[0011] 3. Intelligent linkage between blood glucose and resistance: By integrating an abdominal belt-type blood glucose monitoring module and linking it with the controller, the controller automatically adjusts the resistance based on real-time blood glucose data. When blood glucose is abnormal, it automatically reduces the resistance or locks the resistance increase function, realizing closed-loop safety control based on physiological parameters. This effectively reduces the risk of hypoglycemia or hyperglycemia-related safety events in diabetic sarcopenia patients during exercise training.

[0012] 4. Multiple safety protection mechanisms: Buffer springs and buffer plates at both ends of the guide carriage absorb the impact energy when the foot pedal slider slides to the end, protecting the patient's joints; a low battery alarm module prevents sudden resistance changes due to battery depletion during training; and the controller's blood glucose linkage protection logic prevents excessive training load in hypoglycemic states. These multiple safety designs ensure the device's safety in clinical use.

Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0018] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout.

[0019] In this invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0020] In the description of this invention, "first feature" and "second feature" may include one or more of the indicated features. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined with "first" and "second" may explicitly or implicitly include one or more of the indicated features.

[0021] Please refer to the attached diagram below. Figures 1-5 This invention describes a rehabilitation training device for diabetic sarcopenia patients according to an embodiment of the present invention. The device includes a fixation module, a training module, a blood glucose monitoring module, and a controller. The fixation module serves as the mounting base for the entire device, used to detachably fix the device to the foot of the hospital bed. The fixation module includes a fixation frame 1 and a first fixing member 2 disposed on the fixation frame 1. The fixation frame 1 is detachably mounted laterally at the foot of the hospital bed via the first fixing member 2.

[0022] like Figure 1 As shown, the training modules are positioned at the front of the mounting frame 1 and can be adjusted left and right. There are two training modules, arranged side-by-side, one on the left and one on the right, corresponding to the patient's left and right legs respectively. The mounting frame 1 is equipped with a spacing adjustment mechanism connected to the two training modules. The spacing adjustment mechanism drives the two training modules to move towards or away from each other, thereby adjusting the spacing between them. Different patients have different body shapes and hip joint widths; by adjusting the spacing, the device can be adapted to patients of different body types, ensuring that both legs are in a comfortable position for exertion during training.

[0023] like Figures 2-4 As shown, the training module includes a base 3, a guide slide 4, a foot pedal slider 5, a buffer assembly, an angle adjustment mechanism, and a resistance adjustment mechanism. The base 3 is connected to the aforementioned spacing adjustment mechanism, which drives the base 3 to move, thereby moving the entire training module. The guide slide 4 is positioned above the base 3, and its front end is hinged to the base 3. The base 3 has an angle adjustment mechanism that drives the guide slide 4 to rotate around the hinge point, thus adjusting the tilt angle of the guide slide 4 relative to the horizontal plane. For bedridden patients with weak muscle strength, the guide slide 4 can be adjusted to a near-horizontal, small angle. In this state, training primarily overcomes the resistance provided by the resistance adjustment mechanism, without needing to counteract gravity, allowing the patient to safely begin training. As the patient's muscle strength gradually recovers, the tilt angle of the guide slide 4 can be gradually increased to increase the gravitational load, achieving progressive rehabilitation training.

[0024] The foot pedal slider 5 is slidably mounted on the guide slide 4. After the patient fixes their foot on the foot pedal slider 5, the flexion and extension movements of the lower limbs drive the foot pedal slider 5 to slide back and forth along the guide slide 4. A second fixing component is provided on the foot pedal slider 5 to reliably secure the patient's foot on it, preventing slippage during training. Buffer components are provided at both the front and rear ends of the guide slide 4. When the foot pedal slider 5 slides to the end of the guide slide 4, the buffer components absorb impact energy, providing cushioning and shock absorption to prevent hard impacts from damaging the patient's joints. The guide slide 4 also has a resistance adjustment mechanism, which adjusts the resistance encountered by the foot pedal slider 5 as it slides along the guide slide 4. By adjusting the resistance, the training intensity can be matched to the patient's muscle strength level, achieving individualized rehabilitation training.

[0025] like Figure 1 As shown, the blood glucose monitoring module is used to monitor the patient's blood glucose level in real time during training. Specifically, the blood glucose monitoring module includes an abdominal band 6 and a blood glucose sensor 7. The abdominal band 6 is mounted on the mounting bracket 1 and is wrapped around the patient's abdomen. The blood glucose sensor 7 is mounted on the abdominal band 6. After the patient wears the abdominal band 6, the blood glucose sensor 7 is in contact with the patient's abdominal skin, continuously collecting glucose concentration data in the interstitial fluid and transmitting the blood glucose data to the controller wirelessly. The abdomen was chosen as the sensor's wearing location because the abdominal muscles do not actively contract during training, preventing muscle deformation from compressing the sensor and causing reading deviations. Furthermore, the abdomen is not compressed when the patient is supine, ensuring the accuracy and stability of blood glucose monitoring.

[0026] The controller is electrically connected to the spacing adjustment mechanism, angle adjustment mechanism, resistance adjustment mechanism, and blood glucose sensor 7. The controller is configured to automatically adjust the resistance of the resistance adjustment mechanism based on the blood glucose parameters collected by the blood glucose sensor 7. For example, when the controller receives a blood glucose value lower than a preset safety threshold, it automatically reduces the resistance of the resistance adjustment mechanism to lessen the training load and prevent the patient from experiencing danger due to excessive training intensity in a hypoglycemic state; when the blood glucose value returns to normal, the preset training resistance is restored. This blood glucose-resistance linkage mechanism is a key innovation of this invention, distinguishing it from existing technologies.

[0027] Therefore, the rehabilitation training device for diabetic sarcopenia patients provided in this embodiment of the invention meets the training needs of bedridden patients by detachably installing the fixed module at the end of the hospital bed; by setting up dual training modules with adjustable spacing and guide slide 4 with adjustable angle, it can adapt to patients of different body types and achieve progressive rehabilitation; by integrating a blood glucose monitoring module and linking it with the resistance adjustment mechanism, it realizes intelligent training safety protection based on blood glucose level, effectively reducing the risk of hypoglycemia in diabetic sarcopenia patients during exercise training.

[0028] In some embodiments, the first fastener 2 is a first strap with Velcro, and the second fastener is a second strap with Velcro.

[0029] In some implementations, such as Figure 2 As shown, the fixing frame 1 has a hollow interior forming a first mounting cavity 9. The front side of the fixing frame 1 has a first sliding groove 8 extending in the left-right direction, which communicates with the first mounting cavity 9. The spacing adjustment mechanism includes a motor and a screw 10. The screw 10 is rotatably mounted in the first mounting cavity 9, and the motor is fixedly mounted in the first mounting cavity 9 and connected to the screw 10 to drive the screw 10 to rotate. The motor is connected to a controller. The screw 10 has two external threads with opposite directions of rotation, and the two bases 3 each have corresponding screw holes. The bases 3 pass through the first sliding groove 8 and are threadedly engaged with the screw 10.

[0030] When the controller drives the motor to rotate forward, the screw 10 causes the two bases 3 to move towards each other along the first slide groove 8, reducing the distance between the two training modules. When the motor rotates in reverse, the two bases 3 move away from each other, increasing the distance. By driving the screw 10 with the motor, stepless and precise adjustment of the distance can be achieved, and the two training modules always maintain symmetrical movement during the adjustment process, ensuring that the patient's legs are in symmetrical training positions.

[0031] In some implementations, such as Figure 3 As shown, the angle adjustment mechanism includes an electric push rod 11, which is connected to a controller. The upper side of the base 3 is provided with a receiving groove 12, in which the electric push rod 11 is housed. One end of the electric push rod 11 is hinged to the base 3, and the other end is hinged to the guide slide 4.

[0032] When the telescopic rod of the electric push rod 11 extends, it pushes the guide slide 4 to rotate upward around the front hinge point, increasing the angle between the guide slide 4 and the horizontal plane; when the telescopic rod retracts, the guide slide 4 rotates downward, decreasing the tilt angle. The extension and retraction of the electric push rod 11 is precisely controlled by the controller, enabling stepless adjustment of the tilt angle to meet the training needs of different rehabilitation stages. Storing the electric push rod 11 within the receiving slot 12 makes the structure more compact and avoids interference or damage caused by the electric push rod 11 being exposed.

[0033] In some implementations, such as Figure 4 As shown, the guide slide 4 has a hollow interior forming a second mounting cavity 13. The left and right sides of the guide slide 4 are respectively provided with second slide grooves 14 extending in the front-back direction. The second slide grooves 14 are connected to the second mounting cavity 13. The second mounting cavity 13 is provided with a slide plate 15. The slide plate 15 passes outward through the second slide grooves 14 on both sides and then connects upward to the foot pedal slider 5.

[0034] Specifically, the guide slide 4 adopts a hollow profile structure, forming a second mounting cavity 13 inside. A long, narrow second slide groove 14 extending in the front-to-back direction is formed on the left and right sides of the guide slide 4. The two second slide grooves 14 are arranged opposite each other and both communicate with the second mounting cavity 13. The slide plate 15 is disposed within the second mounting cavity 13. Its main body is flat, and the left and right edges of the slide plate 15 pass through the left and right second slide grooves 14 respectively, extending outwards from the second mounting cavity 13. The portion of the slide plate 15 passing through the second slide grooves 14 is bent upwards or connected to a connecting seat, and is fixedly connected to the bottom of the foot pedal slider 5. When the patient drives the foot pedal slider 5 to slide, the foot pedal slider 5 drives the slide plate 15 to move synchronously within the second mounting cavity 13. The left and right edges of the slide plate 15 slide within the second slide grooves 14, serving a guiding and limiting function.

[0035] In some embodiments, buffer assemblies are provided at the front and rear ends of the second mounting cavity 13, and the buffer assemblies include a buffer plate 16 and a buffer spring 17. The buffer plate 16 faces the slide plate 15, and the buffer spring 17 is connected between the buffer plate 16 and the guide slide 4.

[0036] When the slide plate 15 slides within the second mounting cavity 13 and approaches its end, the end of the slide plate 15 first contacts the buffer plate 16, pushing the buffer plate 16 to compress the buffer spring 17. The elastic deformation of the buffer spring 17 absorbs the kinetic energy of the slide plate 15, causing the slide plate 15 to gradually decelerate until it stops, thus avoiding a direct rigid collision between the slide plate 15 and the end wall of the guide carriage 4. After training, the buffer spring 17 returns to its original deformation, pushing the buffer plate 16 back to its initial position. By setting the buffer spring 17 and the buffer plate 16, the impact energy when the foot pedal slider 5 slides to its end can be effectively absorbed, protecting the patient's joints from impact damage and also improving the service life of the device.

[0037] In some implementations, such as Figure 4 and Figure 5 As shown, the resistance adjustment mechanism includes a permanent magnet 18 and an electromagnet 19. The permanent magnet 18 is fixedly embedded in the slide plate 15. The upper and lower surfaces of the second mounting cavity 13 are respectively provided with a number of electromagnets 19 arranged in the front-back direction. The electromagnets 19 are connected to the controller. The controller is used to generate controllable magnetic resistance to the sliding of the slide plate 15 by adjusting the current magnitude and / or the on-off sequence of the electromagnets 19.

[0038] Specifically, one or more permanent magnets 18 are embedded in the upper and lower surfaces of the slide plate 15, and multiple electromagnets 19 are fixedly installed on the upper and lower inner walls of the second mounting cavity 13. These electromagnets 19 are evenly arranged in the front-to-back direction to form an array of electromagnets 19. Each electromagnet 19 is electrically connected to a controller, which can independently control the current magnitude and on / off timing of each electromagnet 19. When an electromagnet 19 is energized, it generates a magnetic field, which interacts with the magnetic field of the permanent magnets 18 on the slide plate 15 to produce magnetic attraction or repulsion. When the slide plate 15 slides within the second mounting cavity 13, the permanent magnets 18 on the slide plate 15 pass by each electromagnet 19 in sequence. The controller controls the on / off timing of the corresponding electromagnets 19 according to the real-time position of the slide plate 15, so that the magnetic resistance can be applied to the slide plate 15 according to a preset rule. By adjusting the current magnitude of the electromagnets 19, the magnetic field strength can be changed, thereby adjusting the resistance magnitude; by controlling the on / off timing, dynamic resistance adjustment during the movement of the slide plate 15 can be achieved. This electromagnetic resistance adjustment method has a fast response speed, no mechanical contact wear, and can achieve stepless adjustment. It is particularly suitable for linkage with blood glucose monitoring functions to achieve millisecond-level safe response.

[0039] For example, during a complete reciprocating cycle of the foot pedal slider 5, the controller detects the direction of movement of the slide plate 15 (e.g., by using a Hall sensor or photoelectric sensor) and provides less resistance during the patient's push-off phase (concentric contraction) to reduce training energy consumption and avoid hypoglycemia induced by excessive exercise load; during the patient's return phase (eccentric contraction), it provides greater resistance, requiring the patient to exert force to control the foot pedal slider 5 to slowly fall back, thereby enhancing the eccentric training effect. This asymmetric resistance control mode is designed specifically for the clinical characteristics of diabetic sarcopenia patients, namely "poor eccentric control ability and low exercise endurance," and can effectively promote the recovery of lower limb muscle strength while ensuring training safety.

[0040] In some embodiments, the foot pedal slider 5 has a groove for accommodating the foot. The groove is roughly foot-shaped and about 2-3 cm deep. After the patient places their foot in the groove, the sidewalls of the groove can limit the foot and prevent lateral slippage during training. The bottom surface of the groove can be provided with anti-slip texture or soft padding to improve comfort and anti-slip performance.

[0041] In some embodiments, the mounting bracket 1 integrates a rechargeable battery, which is electrically connected to the spacing adjustment mechanism, the angle adjustment mechanism, the resistance adjustment mechanism, and the controller; the battery is also equipped with a power display module and a low power alarm module.

[0042] Specifically, the mounting frame 1 has a battery compartment inside or outside, containing a rechargeable lithium battery. The battery supplies power to the motor, electric actuator 11, electromagnet 19, controller, and other electrical components via power lines. A power display module is connected to the battery; this module can be a set of LED indicators that display the remaining battery power through different colors or flashing frequencies. A low-battery alarm module is linked to the power display module; when the battery power falls below a preset threshold, the alarm module emits an audible and visual alarm signal to remind medical staff or family members to charge the battery promptly. By integrating a rechargeable battery, the device is freed from the constraints of a power cord, facilitating flexible use at the bedside. The power display and low-battery alarm functions prevent the device from suddenly stopping due to depletion of power, thus preventing sudden changes in resistance from causing harm to the patient.

[0043] In some implementations, the controller is an independently configured remote control, which is configured to: automatically reduce the resistance value of the resistance adjustment mechanism when the blood glucose value measured by the blood glucose sensor 7 is lower than a first preset threshold; prohibit increasing the resistance value of the resistance adjustment mechanism when the blood glucose value is higher than a second preset threshold; and restore the manual adjustment function when the blood glucose value returns to the normal range.

[0044] Specifically, the controller uses an independent handheld remote control that communicates wirelessly with the blood glucose sensor 7, motor, electric push rod 11, electromagnet 19, and other actuators. The remote control is equipped with a display screen and multiple operation buttons. The display screen shows real-time information such as blood glucose level, current resistance level, guide slide angle 4, and battery level. The operation buttons are used to manually adjust the resistance, guide slide angle 4, and the distance between the two modules.

[0045] The controller has a first preset threshold (e.g., 5.0 mmol / L) and a second preset threshold (e.g., 13.0 mmol / L). When the blood glucose value received from the blood glucose sensor 7 is lower than the first preset threshold, the controller determines that the patient is at risk of hypoglycemia and automatically sends a command to the resistance adjustment mechanism to reduce the resistance value to a preset safe level (e.g., minimum level or zero resistance), while simultaneously issuing an alarm through the display screen and buzzer. When the blood glucose value is higher than the second preset threshold, the controller determines that the patient is in a hyperglycemic state. At this time, it prohibits responding to any manual operation commands to increase resistance, i.e., it locks the resistance increase function, allowing only low-intensity training or pausing training. When the blood glucose value returns to the normal range (e.g., between 5.0-13.0 mmol / L), the controller resumes its response to the manual adjustment function, allowing the patient or medical staff to adjust the resistance level as needed. This intelligent blood glucose-resistance linkage control mechanism is the core innovation of this invention, which distinguishes it from existing technologies. It can effectively ensure the safety of exercise training for patients with diabetic sarcopenia and avoid dangerous events such as hypoglycemia or hyperglycemia induced by exercise.

[0046] In summary, this device has the following characteristics: 1. High adaptability to bedridden scenarios: By detachably installing the fixed module at the end of the hospital bed, and in conjunction with the guide slide 4 and foot pedal slider 5 structure, patients can perform lower limb resistance training in a supine position, which solves the limitation of existing devices that are only suitable for sitting or standing positions, and fills the gap in rehabilitation training devices for bedridden diabetic sarcopenia patients.

[0047] 2. Strong individualized rehabilitation capability: By setting up dual training modules with adjustable spacing, guide slide 4 with electrically adjustable tilt angle, and electromagnetic resistance adjustment mechanism, the training parameters can be flexibly adjusted according to the patient's body type, muscle strength level and rehabilitation stage, realizing full-cycle progressive rehabilitation training from the initial bed rest to the recovery of walking. One device covers multiple rehabilitation stages.

[0048] 3. Intelligent linkage between blood glucose and resistance: By integrating the abdominal belt with a 6-type blood glucose monitoring module and linking it with the controller, the controller automatically adjusts the resistance based on real-time blood glucose data. When blood glucose is abnormal, it automatically reduces the resistance or locks the resistance increase function, realizing closed-loop safety control based on physiological parameters. This effectively reduces the risk of hypoglycemia or hyperglycemia-related safety events in diabetic sarcopenia patients during exercise training.

[0049] 4. Multiple safety protection mechanisms: By setting buffer springs 17 and buffer plates 16 at both ends of the guide slide 4, the impact energy when the foot pedal slider 5 slides to the end is absorbed, protecting the patient's joints; by setting a low battery alarm module, the resistance sudden change caused by battery depletion during training is prevented; and by using the blood glucose linkage protection logic of the controller, the training load is prevented from being too high in a hypoglycemic state. Multiple safety designs ensure the safety of the device in clinical use.

[0050] Although some embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and variations of these embodiments without departing from the principles and spirit of the present invention are within the scope of protection of the claims of the present invention.
