Description

Technical Field

[0001] This invention relates to the field of medical devices, and more specifically, to a respiratory support device for tuberculosis patients based on their movement status. Background Technology

[0002] In the medical field, tuberculosis patients have impaired lung function and significantly reduced breathing capacity compared to healthy individuals. Especially during exercise, the body's demand for oxygen increases, further exacerbating the respiratory burden. In such cases, specialized respiratory assistive devices are needed to improve breathing conditions, maintain normal oxygen supply, and ensure the stability and safety of the patient's breathing during exercise.

[0003] With the development of medical concepts, the rehabilitation process for tuberculosis patients is no longer limited to bed rest. Moderate exercise is of great significance for enhancing patients' physical fitness and improving cardiopulmonary function. However, when patients exercise, their bodies are in a dynamic state. Existing conventional respiratory assist devices generally rely on patients to hold the device with their hands to complete the operation. This operation method conflicts with the patient's exercise needs, causing great inconvenience when patients are engaged in physical activities, affecting the user experience and freedom of movement.

[0004] Currently, existing technologies for respiratory assistance during exercise for tuberculosis patients have significant shortcomings in practical applications. Existing technologies struggle to achieve stable binding and precise positioning of the device to the patient's waist. They cannot adjust the core respiratory assistance components to a reasonable position that efficiently assists breathing without interfering with movement, based on the patient's body structure and exercise needs. This results in the device easily shifting during exercise, affecting the assistance effect. Summary of the Invention

[0005] To address the problem that existing technologies struggle to achieve stable binding and precise positioning of the device to the patient's waist, and cannot adjust the core respiratory assist components to a reasonable position that efficiently assists breathing without interfering with movement based on the patient's body structure and movement needs, leading to easy displacement of the device during movement and affecting the assistive effect, the purpose of this invention is to provide a respiratory assist device for tuberculosis patients based on movement status.

[0006] To solve the above problems, the present invention adopts the following technical solution:

[0007] A respiratory support device for tuberculosis patients based on motion status includes a respiratory support device, and a binding component is provided on one side of the respiratory support device for binding to the user's waist;

[0008] The binding assembly includes a pair of oppositely arranged mounting brackets, each mounting bracket having a self-displacement component. The self-displacement component includes a sliding frame, on which a breathing aid is connected via a connecting component. The self-displacement component is used to move the installed breathing aid to the user's lower back. The connecting component has a damping component for cushioning vibrations during the user's movement.

[0009] Optionally, each of the mounting brackets is fixedly mounted with straps on both sides, and a winding shaft with a limiting component is fixedly mounted on the end of the straps away from the mounting bracket. The winding shaft is rotatably mounted in a winding box, and the winding shaft connects the two straps on the same side to realize the connection between the two mounting brackets.

[0010] Optionally, the limiting component includes a limiting groove formed on the take-up shaft, a sliding groove formed on the take-up box, a mounting slide slidably installed in the sliding groove, a locking block rotatably installed on the mounting slide that cooperates with the limiting groove, a spring piece fixedly installed on the mounting slide, and the other end of the spring piece being fixedly connected to the locking block.

[0011] Optionally, a first spring is fixedly installed on the mounting bracket, and the other end of the first spring is fixedly connected to the inner wall of the slide groove.

[0012] Optionally, the self-displacement component includes an airbag fixedly mounted on a mounting frame, a sliding frame slidably mounted inside the mounting frame, a hollow sleeve communicating with the airbag fixedly mounted inside the mounting frame, a sliding column slidably mounted inside the hollow sleeve, and one end of the sliding column away from the hollow sleeve being fixedly connected to the sliding frame.

[0013] Optionally, a ball bearing is movably disposed on the sliding frame, and the surface of the ball bearing is in contact with the inner wall of the mounting frame.

[0014] Optionally, the connecting assembly includes a mounting plate slidably mounted in a sliding frame, a positioning post fixedly mounted on the mounting plate, a locking plate slidably mounted on the positioning post, a second spring fixedly mounted on the bottom surface of the top of the locking plate, the other end of the second spring being fixedly connected to the top surface of the mounting plate, a first slot that mates with the mounting plate being provided on the side wall of the breathing aid, and a second slot that mates with the locking plate being provided on the top surface of the breathing aid.

[0015] Optionally, one end of a third spring is fixedly installed on the bottom of the mounting plate, and the other end of the third spring is fixedly connected to the inner bottom wall of the sliding frame.

[0016] Optionally, the damping assembly includes a first through hole on the bottom protruding end of the mounting plate, a pair of protrusions are fixedly mounted on the bottom protruding end of the mounting plate, a rotating plate is rotatably connected to the protrusions by a coil spring, and a second through hole coaxial with the first through hole is provided on the rotating plate.

[0017] Optionally, a reset assembly is provided inside the airbag. The reset assembly includes a fourth spring disposed inside the airbag, and two ends of the fourth spring are fixedly mounted with abutments, which abut against the inner wall of the airbag. Compared with the prior art, the technical solution provided by the present invention has at least the following beneficial effects:

[0018] In the above solution, a binding component is used to stably secure the entire device to the user's waist, providing a fixed mounting base for the ventilator and ensuring that the device will not easily fall off or shift during the user's activities. Then, a self-displacement component moves the ventilator mounted on the sliding frame, ultimately precisely adjusting it to a position on the user's lower back. This position better matches the user's breathing rhythm and reduces interference with daily activities, facilitating patient movement and ensuring freedom of movement.

[0019] By incorporating a damping component, when a user is in motion, their body will vibrate. The damping component will then buffer these vibrations, preventing them from being transmitted to the breathing aid and affecting its normal operation. It will also reduce the discomfort caused by the vibration to the user's lower back, ensuring that the breathing aid can stably and comfortably assist the user's breathing during exercise.

[0039] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments. It should also be noted that, to make the embodiments more comprehensive, the following embodiments are the best and preferred embodiments, and those skilled in the art can use other alternative methods to implement some well-known technologies; moreover, the accompanying drawings are only for more specific description of the embodiments and are not intended to specifically limit the present invention.

[0040] It should be noted that the use of terms such as "an embodiment," "an embodiment," "an exemplary embodiment," and "some embodiments" in the specification indicates that the described embodiment may include a specific feature, structure, or characteristic, but not every embodiment necessarily includes that specific feature, structure, or characteristic. Furthermore, when a specific feature, structure, or characteristic is described in connection with an embodiment, implementing such a feature, structure, or characteristic in conjunction with other embodiments (whether explicitly described or not) should be within the knowledge of those skilled in the art.

[0041] Generally, terms can be understood at least partly from their use in context.

Additionally, the term "based on" can be understood not necessarily to convey an exclusive set of factors, but rather, alternatively, depending at least partly on the context, to allow for the presence of other factors that are not necessarily explicitly described.

[0042] It is understood that the meanings of “on”, “above”, and “above” in this invention should be interpreted in the broadest manner, such that “on” means not only “directly on” something, but also includes the meaning of being “on” something with an intervening feature or layer, and that “above” or “above” means not only “on” something, but also includes the meaning of being “on” something without an intervening feature or layer.

[0043] Furthermore, spatially related terms such as “below,” “under,” “lower,” “above,” and “upper” are used herein for convenience to describe the relationship of one element or feature to one or more other elements or features, as illustrated in the accompanying drawings. Spatially related terms are intended to cover different orientations in the use or operation of the device other than those depicted in the accompanying drawings. The device may be oriented in other ways, and the spatially related descriptive terms used herein can be interpreted similarly.

[0044] For example Figures 1 to 9 As shown, this embodiment of the invention provides a respiratory assist device for tuberculosis patients based on motion state, including a respiratory assist device 10, wherein a binding component 20 is provided on one side of the respiratory assist device 10, and the binding component 20 is used to bind to the user's waist.

[0045] The binding component 20 includes two mounting brackets 21 arranged opposite to each other. A self-displacement component 40 is provided on the mounting bracket 21. The self-displacement component 40 includes a sliding frame 44. A breathing aid 10 is connected to one of the sliding frames 44 through a connecting component 50. The self-displacement component 40 is used to move the breathing aid 10 to the user's lower back after installation. The connecting component 50 includes a mounting plate 51. A damping component 60 is provided on the mounting plate 51. The damping component 60 is used to buffer the vibration during the user's movement.

[0046] First, the binding component 20 securely binds the entire device to the user's waist, providing a fixed mounting base for the breathing assist device 10 and ensuring that the device will not easily fall off or shift during the user's activities. Next, the self-displacement component 40 takes effect, moving the breathing assist device 10 mounted on the sliding frame 44. Finally, the breathing assist device 10 is precisely adjusted to the user's lower back position, which better matches the user's breathing rhythm and reduces interference with daily activities. Finally, when the user is in motion, the body will vibrate. At this time, the damping component 60 will buffer these vibrations, preventing the vibrations from being transmitted to the breathing assist device 10 and affecting its normal operation. It can also reduce the discomfort caused by vibrations to the user's waist, ensuring that the breathing assist device stably and comfortably assists the user's breathing in motion scenarios.

[0047] like Figures 1 to 4 As shown, a pair of straps 22 are fixedly installed on each of the mounting frames 21. A winding shaft 24 with a limiting component 30 is fixedly installed at the end of the strap 22 away from the mounting frame 21. The winding shaft 24 is rotatably installed in the winding box 23. The winding shaft 24 connects the two straps 22 on the same side together.

[0048] When using the binding component 20 to bind the waist, a pair of mounting brackets 21 serve as the basic support structure, on which the binding straps 22 are fixed for wrapping around the user's waist. When the tightness of the binding straps 22 needs to be adjusted, the winding shaft 24 is rotated. The winding shaft 24 will wind or unwind the binding straps 22, thereby changing the length of the binding straps 22 around the waist. The limiting component 30 restricts the rotation of the winding shaft 24. After adjusting to the appropriate tightness, the limiting component 30 fixes the position of the winding shaft 24 to prevent the winding shaft 24 from rotating on its own during use, which would cause the binding straps 22 to become loose or too tight. This ensures that the binding straps 22 can always bind the device to the waist with the appropriate tightness. Through the cooperation of the winding shaft 24 and the limiting component 30, the tightness of the binding straps 22 can be flexibly and precisely adjusted to meet the needs of users with different waist sizes. At the same time, it ensures the stability after binding and avoids affecting the use of the device or causing user discomfort due to improper tightness of the binding straps 22.

[0049] The limiting component 30 includes a limiting groove 31 formed on the take-up shaft 24, a sliding groove 35 formed on the take-up box 23, a mounting slide 32 slidably installed in the sliding groove 35, a locking block 33 that cooperates with the limiting groove 31 is rotatably installed on the mounting slide 32, and a spring piece 34 is fixedly installed on the mounting slide 32, with the other end of the spring piece 34 fixedly connected to the locking block 33;

[0050] When the take-up shaft 24 needs to be rotated to adjust the strap 22, an external force is applied to the take-up shaft 24. The rotation of the take-up shaft 24 will exert a force on the locking block 33. Since the locking block 33 is rotatably mounted on the mounting slide 32, and there is a spring piece 34 between the locking block 33 and the mounting slide 32, under the force of the rotation of the take-up shaft 24, the locking block 33 will overcome the elasticity of the spring piece 34 and rotate, disengaging from the locking state with the upper limit groove 31 of the take-up shaft 24. At this time, the take-up shaft 24 can rotate freely to wind up the strap 22. After adjusting to the appropriate tightness, the external force is removed, and the spring piece 34 will drive the locking block 33 to rotate and re-lock into the corresponding limit groove 31 of the take-up shaft 24. The mounting slide 32 can slide in the slide groove 35 of the take-up box 23. When it is necessary to release the strap 22, slide the mounting slide 32 away from the take-up shaft 24, which will drive the locking block 33 to release the restriction on the limit groove 31.

[0051] like Figures 1 to 9 As shown, a first spring 36 is fixedly installed on the mounting slide 32, and the other end of the first spring 36 is fixedly connected to the inner wall of the slide groove 35.

[0052] The first spring 36 has elastic deformation capability and will deform accordingly as the mounting slide 32 slides, while generating a reverse elastic force. This elastic force will reset the sliding of the mounting slide 32. When the mounting slide 32 is pulled away from the winding shaft 24, it will squeeze the first spring 36. When the mounting slide 32 is released, the first spring 36 will drive the mounting slide 32 to reset.

[0053] The self-displacement component 40 includes an airbag 41 fixedly installed on a mounting frame 21. The mounting frame 21 has an arc-shaped frame structure. A sliding frame 44 is slidably installed inside the mounting frame 21. A hollow sleeve 42 communicating with the airbag 41 is fixedly installed inside the mounting frame 21. A sliding column 43 is slidably installed inside the hollow sleeve 42. One end of the sliding column 43 away from the hollow sleeve 42 is fixedly connected to the sliding frame 44.

[0054] When the mounting bracket 21 is strapped to the user's body and the strap 22 is tightened, the airbag 41 will be compressed, and the gas inside the airbag 41 will enter the hollow sleeve 42. As the gas pressure inside the hollow sleeve 42 increases, it will generate a thrust on the sliding column 43 that is slidably mounted inside the hollow sleeve 42, pushing the sliding column 43 to slide outward along the axial direction of the hollow sleeve 42. Since the end of the sliding column 43 away from the hollow sleeve 42 is fixedly connected to the sliding frame 44, the sliding of the sliding column 43 will drive the sliding frame 44 to slide within the mounting bracket 21. The breathing aid 10 is mounted on the sliding frame 44 through the connecting component 50. Therefore, the sliding of the sliding frame 44 will eventually drive the breathing aid 10 to move together until the breathing aid 10 is moved to the target position on the user's lower back. This will not affect the user's arm swing when jogging and will improve the breathing assistance effect.

[0055] A ball bearing 45 is movably disposed on the sliding frame 44, and the surface of the ball bearing 45 is in contact with the inner wall of the mounting frame 21.

[0056] When the self-displacement component 40 drives the sliding frame 44 to slide within the mounting frame 21, the movable ball bearings 45 on the sliding frame 44 directly contact the inner wall of the mounting frame 21. During the sliding process, the ball bearings 45 will roll as the sliding frame 44 moves, transforming the sliding friction between the sliding frame 44 and the inner wall of the mounting frame 21 into rolling friction. The frictional force of rolling friction is much smaller than that of sliding friction, greatly reducing the resistance encountered by the sliding frame 44 when sliding within the mounting frame 21. This makes the sliding of the sliding frame 44 smoother and easier, avoiding the sliding frame 44 from getting stuck due to excessive sliding resistance, which would affect the accuracy and convenience of adjusting the position of the breathing aid 10.

[0057] The connecting assembly 50 includes an L-shaped mounting plate 51 slidably mounted within a sliding frame 44. A positioning post 52 is fixedly mounted on the mounting plate 51, and an L-shaped locking plate 53 is slidably mounted on the positioning post 52. A second spring 56 is fixedly mounted on the bottom surface of the top of the locking plate 53, and the other end of the second spring 56 is fixedly connected to the top surface of the mounting plate 51. The second spring 56 is sleeved on the positioning post 52. A first slot 54 that mates with the mounting plate 51 is provided on the side wall of the breathing aid 10, and a second slot 55 that mates with the locking plate 53 is provided on the top of the breathing aid 10.

[0058] When installing the breathing aid 10 onto the sliding frame 44 via the connecting assembly 50, firstly, pull the positioning plate 53 to slide it away from the mounting plate 51 on the positioning post 52 and stretch the second spring 56. Then, align the protrusion of the mounting plate 51 with the first slot 54 on the breathing aid 10 and insert it. After the mounting plate 51 is inserted into the first slot 54, release the positioning plate 53. The second spring 56 drives the positioning plate 53 to reset and insert into the second slot 55. Through the cooperation of the mounting plate 51 with the first slot 54 and the cooperation of the positioning plate 53 with the second slot 55, the breathing aid 10 is quickly and firmly fixed onto the sliding frame 44.

[0059] One end of a third spring 57 is fixedly installed on the insertion part of the mounting plate 51, and the other end of the third spring 57 is fixedly connected to the inner bottom wall of the sliding frame 44.

[0060] The bumps generated during a user's jogging activity will cause the mounting plate 51 to slide within the sliding frame 44 and compress the third spring 57. The third spring 57 can cushion the bumps and improve the stability of the equipment.

[0061] like Figures 8 to 9 As shown, the damping assembly 60 includes a first through hole 61 opened on the protruding end of the mounting plate 51. A pair of protrusions 62 are fixedly installed on the protruding end of the mounting plate 51. A rotating plate 63 is rotatably connected to the protrusions 62 by a coil spring. A second through hole 64 coaxial with the first through hole 61 is opened on the rotating plate 63.

[0062] When the user jogs, the resulting bumps cause the mounting plate 51 to compress the third spring 57. The air inside the sliding frame 44 is compressed and ejected along the first through hole 61, causing the rotating plate 63 to rotate. When the mounting plate 51 descends to a certain position, the third spring 57 will cause the mounting plate 51 to reset. When the mounting plate 51 resets, the coil spring will cause the rotating plate 63 to reset. At this time, the air enters the sliding frame 44 along the second through hole 64 and the first through hole 61. Since the diameter of the second through hole 64 is smaller than that of the first through hole 61, the air will slowly enter the sliding frame 44, making the mounting plate 51 reset slowly, which has a damping effect. Together with the third spring 57, it has a good buffering effect.

[0063] like Figure 6 As shown, a reset assembly 70 is provided inside the airbag 41. The reset assembly 70 includes a fourth spring 71 disposed inside the airbag 41. Abutment plates 72 are fixedly installed at both ends of the fourth spring 71, and the abutment plates 72 abut against the inner wall of the airbag 41.

[0064] When the binding component 20 is removed from the user, the fourth spring 71 drives a pair of abutments 72 to open the airbag 41 and restore it to its original position. When the airbag 41 is reset, it will drive the sliding column 43 to reset. When the sliding column 43 is reset, it will drive the sliding frame 44 and the breathing aid 10 to a position that is easy for the user to remove for the next use.

[0065] The specific workflow of the technical solution provided by this invention is as follows:

[0066] First, the binding component 20 securely binds the entire device to the user's waist, providing a fixed mounting base for the breathing assist device 10 and ensuring that the device will not easily fall off or shift during the user's activities. Next, the self-displacement component 40 takes effect, driving the breathing assist device 10, which is mounted on the sliding frame 44 (connected by the connecting component 50), to move. Finally, the breathing assist device 10 is precisely adjusted to the user's lower back position, which better matches the user's breathing rhythm and reduces interference with daily activities. Finally, when the user is in motion, the body will vibrate. At this time, the damping component 60 will buffer these vibrations to prevent the vibrations from being transmitted to the breathing assist device 10 and affecting its normal operation. It can also reduce the discomfort caused by the vibrations to the user's waist, ensuring that the breathing assist device can stably and comfortably assist the user's breathing in motion scenarios.

[0067] When using the binding component 20 to bind the waist, a pair of mounting brackets 21 serve as the basic support structure, on which the binding strap 22 is fixed for wrapping around the user's waist. When it is necessary to adjust the tightness of the binding strap 22, the winding shaft 24 is rotated. The winding shaft 24 will wind or release the binding strap 22, thereby changing the length of the binding strap 22 around the waist. The limiting component 30 restricts the rotation of the winding shaft 24. After adjusting to the appropriate tightness, the limiting component 30 fixes the position of the winding shaft 24 to prevent the winding shaft 24 from rotating on its own during use, which would cause the binding strap 22 to become loose or too tight. This ensures that the binding strap 22 can always bind the device to the waist with the appropriate tightness. Through the cooperation of the winding shaft 24 and the limiting component 30, the tightness of the binding strap 22 can be flexibly and accurately adjusted to meet the needs of users with different waist sizes. At the same time, it ensures the stability after binding and avoids affecting the use of the device or causing user discomfort due to improper tightness of the binding strap 22.

[0068] When the take-up shaft 24 needs to be rotated to adjust the strap 22, an external force is applied to the take-up shaft 24. The rotation of the take-up shaft 24 will exert a force on the locking block 33. Since the locking block 33 is rotatably mounted on the mounting slide 32, and there is a spring piece 34 between the locking block 33 and the mounting slide 32, under the force of the rotation of the take-up shaft 24, the locking block 33 will overcome the elasticity of the spring piece 34 and rotate, disengaging from the locking state with the upper limit groove 31 of the take-up shaft 24. At this time, the take-up shaft 24 can rotate freely to wind up the strap 22. When the appropriate tightness is adjusted, the external force is removed, and the spring piece 34 will drive the locking block 33 to rotate and re-lock into the corresponding limit groove 31 of the take-up shaft 24. The mounting slide 32 can slide in the slide groove 35 of the take-up box 23. When it is necessary to release the strap 22, slide the mounting slide 32 away from the take-up shaft 24, which will drive the locking block 33 to release the restriction on the limit groove 31.

[0069] The first spring 36 has elastic deformation capability and will deform accordingly as the mounting slide 32 slides, while generating a reverse elastic force. This elastic force will reset the sliding of the mounting slide 32. When the mounting slide 32 is pulled away from the winding shaft 24, the first spring 36 will be squeezed. When the mounting slide 32 is released, the first spring 36 will drive the mounting slide 32 to reset.

[0070] When the mounting frame 21 is strapped to the user's body and the strap 22 is tightened, the airbag 41 will be compressed, and the gas inside the airbag 41 will enter the hollow sleeve 42. As the gas pressure inside the hollow sleeve 42 increases, it will generate a thrust on the sliding column 43 that is slidably installed inside the hollow sleeve 42, pushing the sliding column 43 to slide outward along the axis of the hollow sleeve 42. Since the end of the sliding column 43 away from the hollow sleeve 42 is fixedly connected to the sliding frame 44, the sliding of the sliding column 43 will drive the sliding frame 44 to slide within the mounting frame 21. The breathing aid 10 is installed on the sliding frame 44 through the connecting component 50. Therefore, the sliding of the sliding frame 44 will eventually drive the breathing aid 10 to move together until the breathing aid 10 is moved to the target position on the user's lower back. This will not affect the user's arm swing when jogging and will improve the breathing assistance effect.

[0071] When the self-displacement component 40 drives the sliding frame 44 to slide within the mounting frame 21, the movable ball bearing 45 on the sliding frame 44 directly contacts the inner wall of the mounting frame 21. During the sliding process, the ball bearing 45 will roll as the sliding frame 44 moves, transforming the sliding friction between the sliding frame 44 and the inner wall of the mounting frame 21 into rolling friction. The frictional force of rolling friction is much smaller than that of sliding friction, greatly reducing the resistance encountered by the sliding frame 44 when sliding within the mounting frame 21. This makes the sliding of the sliding frame 44 smoother and easier, avoiding the sliding frame 44 from getting stuck due to excessive sliding resistance, which would affect the accuracy and convenience of adjusting the position of the breathing aid 10.

[0072] When installing the breathing aid 10 onto the sliding frame 44 via the connecting assembly 50, first pull the positioning plate 53 away from the mounting plate 51 and stretch the second spring 56. Then, align the mounting plate 51 with the first slot 54 on the breathing aid 10 and insert it. After the mounting plate 51 is inserted into the first slot 54, release the positioning plate 53. The second spring 56 drives the positioning plate 53 to reset and insert into the second slot 55. Through the cooperation of the mounting plate 51 with the first slot 54 and the cooperation of the positioning plate 53 with the second slot 55, the breathing aid 10 is quickly and firmly fixed onto the sliding frame 44.

[0073] The bumps generated during the user's jogging activity will cause the mounting plate 51 to slide within the sliding frame 44 and compress the third spring 57. The third spring 57 can buffer the bumps and improve the stability of the equipment.

[0074] When the user jogs, the resulting bumps cause the mounting plate 51 to compress the third spring 57. The air inside the sliding frame 44 is compressed and ejected along the first through hole 61, causing the rotating plate 63 to rotate. When the mounting plate 51 descends to a certain position, the third spring 57 will cause the mounting plate 51 to reset. When the mounting plate 51 resets, the coil spring will cause the rotating plate 63 to reset. At this time, the air needs to enter the sliding frame 44 along the second through hole 64. Since the diameter of the second through hole 64 is smaller than that of the first through hole 61, the air will slowly enter the sliding frame 44, making the mounting plate 51 reset slowly, which has a damping effect. Together with the third spring 57, it has a good buffering effect.

[0075] When the binding component 20 is removed from the user, the fourth spring 71 drives a pair of abutments 72 to open the airbag 41 and restore it to its original position. When the airbag 41 is reset, it will drive the sliding column 43 to reset. When the sliding column 43 is reset, it will drive the sliding frame 44 and the breathing aid 10 to a position that is easy for the user to remove for the next use.

[0076] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
