Abstract
Description
Technical Field
[0001] The present application relates to the technical field of nutrient solution delivery, and in particular to an enteral nutrition delivery device. Background Art
[0002] In dental clinics, patients who are unable to eat orally or are unable to eat orally often require indwelling gastrointestinal feeding tubes to provide enteral nutrition support. To meet individualized nutritional needs, some patients, unable to afford ready-made nutritional supplements, must prepare homemade nutrient solutions (including homogenized meals, fruit and vegetable juices, etc.) using food ingredients and administer them via gastrointestinal tubes. Existing nutrient solution infusion devices cannot control the temperature of the nutrient solution in the nutrient bag, causing discomfort to the patient. Utility Model Content
[0003] An embodiment of the present application provides an enteral nutrition delivery device that can adjust the temperature of the nutrient solution and alleviate the patient's discomfort.
[0004] The embodiment of the present application provides an enteral nutrition delivery device, the enteral nutrition delivery device comprising a nutrition bag for holding nutrition liquid and an infusion tube for delivering liquid, the top of the nutrition bag is provided with a first liquid inlet for adding nutrition liquid, the bottom of the nutrition bag is provided with a first liquid outlet, the end of the first liquid outlet tube is connected with one end of the infusion tube, and a drip pot and a flow regulator are sequentially provided on the infusion tube along the liquid flow direction of the infusion tube; wherein, the nutrition bag comprises a first bag body and a second bag body, the first bag body is provided on the inner side of the second bag body, the first bag body is used to hold nutrition liquid, the first bag body is connected to the second bag body, and a temperature control cavity is defined between the first bag body and the second bag body, a liquid adding port connected to the interior of the temperature control cavity is provided on one side of the top of the second bag body, the liquid adding port is used to add high-temperature or low-temperature liquid to the interior of the temperature control cavity to exchange heat with the nutrition liquid in the nutrition bag; a liquid discharge port is provided on one side of the bottom of the second bag body, and the liquid discharge port is used to discharge the liquid in the temperature control cavity.
[0005] In this embodiment, nutrient solution can be added to the inner nutrient bag through the first liquid inlet. The nutrient solution is then discharged from the first liquid outlet of the nutrient bag through the infusion tube and delivered to the gastrointestinal tube. A drip pot on the infusion tube is used to monitor the dripping rate of the nutrient solution and whether the infusion is complete, and a flow regulator is used to adjust the delivery rate. Furthermore, the nutrient bag adopts a double-layer bag structure, with the first bag serving as the inner bag for storing the nutrient solution, and the second bag disposed outside the first bag. A temperature-controlled chamber is defined between the second bag and the first bag, and a liquid addition port is provided at the top of the second bag. This port allows for the addition of either high- or low-temperature liquid into the temperature-controlled chamber. For example, if the nutrient solution is heated externally by the user and has a high temperature, low-temperature liquid can be added to the temperature-controlled chamber through the liquid addition port. The low-temperature liquid in the temperature-controlled chamber exchanges heat with the nutrient solution in the first bag, rapidly cooling the nutrient solution to an appropriate temperature. Alternatively, when the nutrient solution is at a low temperature, one or more high-temperature liquids can be added to the temperature-controlled chamber through the liquid-adding port. The high-temperature liquid in the temperature-controlled chamber exchanges heat with the nutrient solution in the first bag, raising the temperature of the nutrient solution. Therefore, the temperature of the nutrient solution can be adjusted according to the patient's condition and needs, improving patient comfort, reducing gastrointestinal irritation, preventing complications such as diarrhea, and improving patient tolerance and therapeutic efficacy of home enteral nutrition.
[0006] In some embodiments, the enteral nutrition delivery device also includes a display component, which includes a controller, a display and a temperature sensor. The temperature sensor is arranged in the first bag body or at the first liquid outlet pipe, and is used to detect the real-time temperature of the nutrient solution in the nutrient bag; the controller is integrated in the display, and the display has a power supply component for providing electrical energy. The display is arranged on the front side of the nutrient bag, and is used to display the temperature information of the nutrient solution in the nutrient bag. The temperature sensor and the display are both electrically connected to the controller.
[0007] In the above technical solution, through the setting of the display component, the display component includes a controller, a display and a temperature sensor. The temperature sensor can detect the temperature of the nutrient solution in the nutrient bag. The temperature information detected by the temperature sensor can be displayed in real time on the display, so that the user can grasp at any time whether the temperature of the nutrient solution reaches the required temperature according to the display. When the temperature of the nutrient solution reaches the required temperature, the user can replenish the nutrient solution to the patient in time without manually measuring the temperature of the nutrient solution. The operation is more convenient, which reduces the user's workload and saves manpower and time.
[0008] In some embodiments, the display assembly further includes a liquid level sensor, which is disposed in the nutrient bag and is used to detect liquid level information of the nutrient solution in the nutrient bag.
[0009] In the above technical solution, by setting up a liquid level sensor, the liquid level information in the nutrient bag can be detected by the liquid level sensor. When the remaining nutrient solution in the nutrient bag is low, the user can replenish or shut down the nutrient solution delivery in time according to the actual situation.
[0010] In some embodiments, the enteral nutrition delivery device also includes a heating component, which is arranged in the temperature control chamber to heat the liquid in the temperature control chamber. The heating component is electrically connected to the controller, and the controller is used to control the heating component according to the temperature information feedback from the temperature sensor to maintain the temperature of the nutrient solution in the nutrient bag at a preset temperature; the display includes a control button and a display screen, the control button is used to input preset information to the controller, and the display screen is used to display information of the nutrient solution in the nutrient bag.
[0011] In the above technical solution, to better control the temperature of the nutrient bag, a heating component is provided within the temperature-control chamber. This heating component can actively heat the liquid within the temperature-control chamber and, through the liquid medium, transfer heat, thereby controlling the temperature of the nutrient solution within the first bag. Once the heating component heats the nutrient solution to a preset temperature, the controller automatically controls the operation of the heating component to maintain the temperature of the nutrient solution at the preset temperature, achieving constant-temperature infusion of the nutrient solution. Parameters can be pre-entered into the controller using control buttons on the display, allowing for selection of preset temperature values for the nutrient solution, thereby meeting the needs of different patients and providing a wider range of applications.
[0012] In some embodiments, the display component also includes a prompter, which is electrically connected to the controller. When the temperature of the nutrient solution in the nutrient bag detected by the temperature sensor reaches a preset temperature; and / or when the liquid level of the nutrient solution in the nutrient bag is lower than a threshold, the controller controls the prompter to send a prompt signal.
[0013] In the above technical solution, a reminder is integrated into the display to serve as a reminder. When the temperature of the nutrient solution in the nutrient bag reaches a preset temperature, as detected by the temperature sensor, indicating that the nutrient solution has reached an appropriate temperature, the reminder issues a message, prompting the user to administer the nutrient solution to the patient. Similarly, when the nutrient solution in the nutrient bag is insufficient, the reminder also issues a message, prompting the user to take timely action to add nutrient solution or stop administering the nutrient solution. This reminder serves as a reminder and prompt, eliminating the need for the user to remain at the patient's side, thus saving manpower.
[0014] In some embodiments, a three-way connector is provided at one end of the infusion tube close to the first liquid outlet tube of the nutrient bag. The three-way connector has a first end, a second end and a third end distributed in a Y shape. The first end is used to connect with the first liquid outlet tube of the nutrient bag, the second end is used to connect with the second liquid outlet tube of the functional bag, and the third end is connected with the infusion tube.
[0015] In the above technical solution, a three-way connector is connected to one end of the infusion tube, and the two ends of the three-way connector can be connected to the nutrient bag and the functional bag respectively. In this way, the nutrient solution and the cleaning solution can be used alternately. By adjusting the flow regulator on the infusion tube, the patient can be provided with continuous and uniform infusion of enteral nutrition, achieving the best nutrient solution injection effect. The functional bag stores cleaning liquid or liquid medicine. When it is necessary to flush the infusion tube or administer medicine, the first liquid outlet tube is closed and the second liquid outlet tube is opened. The liquid in the functional bag can flow into the infusion tube through the second liquid outlet tube to achieve the function of administering medicine or flushing. The infusion tube can be cleaned regularly to avoid repeatedly opening the connection joint between the three-way tube and the first infusion tube, thereby reducing the probability of contaminating the nutrient solution and reducing the workload of the user.
[0016] In some embodiments, the first liquid outlet pipe is provided with a first movable clamp, and the first movable clamp is used to control the opening and closing of the first liquid outlet pipe.
[0017] In the above technical solution, a first movable clamp is provided on the first liquid outlet tube, and the first movable clamp can be used to open or interrupt the first liquid outlet tube to meet the needs of different scenarios. When delivering nutrient solution, the first movable clamp is opened, so that the nutrient solution in the nutrient bag can be connected to the infusion tube through the first liquid outlet tube. When the infusion tube needs to be cleaned or medication needs to be administered, the first movable clamp can be closed.
[0018] In some embodiments, a second movable clamp is provided on the second liquid outlet pipe, and the second movable clamp is used to control the opening and closing of the second liquid outlet pipe.
[0019] In the above technical solution, a second movable clamp is provided on the second liquid outlet tube, which can be used to open or close the second liquid outlet tube to meet different usage scenarios. When delivering nutrient solution, the first movable clamp is opened and the second movable clamp is closed.

[0037] Example
[0038] The present application provides an enteral nutrition delivery device. Figures 1 to 4The enteral nutrition delivery device 100 includes a nutrition bag 10 for containing nutrition liquid and an infusion tube 20 for delivering liquid. The top of the nutrition bag 10 is provided with a first liquid inlet 14 for adding nutrition liquid, and the bottom of the nutrition bag 10 is provided with a first liquid outlet 15. The end of the first liquid outlet 15 is connected to one end of the infusion tube 20. Along the liquid flow direction of the infusion tube 20, a drip pot 21 and a flow regulator 22 are sequentially provided on the infusion tube 20; the nutrition bag 10 includes a first bag body 11 and a second bag body 12. The first bag body 11 is provided inside the second bag body 12 The first bag body 11 is used to hold nutrient solution. The first bag body 11 is connected to the second bag body 12, and a temperature control cavity 13 is defined between the first bag body 11 and the second bag body 12. A liquid adding port 121 communicating with the interior of the temperature control cavity 13 is provided on the top side of the second bag body 12. The liquid adding port 121 is used to add high-temperature or low-temperature liquid to the interior of the temperature control cavity 13 to exchange heat with the nutrient solution in the nutrient bag 10; a drain port 122 communicating with the interior of the temperature control cavity 13 is provided on the bottom side of the second bag body 12. The drain port 122 is used to discharge the liquid in the temperature control cavity 13.
[0039] In this embodiment, nutrient solution can be added to the inner nutrient bag through the first liquid inlet 14. The nutrient solution is then discharged from the first liquid outlet 15 of the nutrient bag 10 and delivered to the gastrointestinal tube through the infusion tube 20. A drip pot 21 on the infusion tube 20 is used to monitor the dripping rate of the nutrient solution and whether the infusion is complete, and a flow regulator 22 is used to adjust the delivery speed. Furthermore, the nutrient bag 10 adopts a double-layer bag structure, with the first bag 11 serving as the inner bag for storing the nutrient solution, and the second bag 12 disposed outside the first bag 11. A temperature-controlled chamber 13 is defined between the second bag 12 and the first bag 11. A liquid addition port 121 is provided at the top of the second bag 12, allowing the addition of high- or low-temperature liquids into the temperature-controlled chamber 13 through the liquid addition port 121. For example, if the nutrient solution is heated externally by the user and has a high temperature, low-temperature liquid can be added to the temperature-controlled chamber 13 through the liquid-adding port 121. The low-temperature liquid in the temperature-controlled chamber 13 exchanges heat with the nutrient solution in the first bag 11, rapidly cooling the nutrient solution to an appropriate temperature. Alternatively, if the nutrient solution is at a low temperature, high-temperature liquid can be added to the temperature-controlled chamber 13 once or multiple times through the liquid-adding port 121. The high-temperature liquid in the temperature-controlled chamber 13 exchanges heat with the nutrient solution in the first bag 11, thereby increasing the temperature of the nutrient solution. Therefore, the provision of the temperature-controlled chamber 13 allows the temperature of the nutrient solution to be adjusted appropriately based on the patient's condition and needs, thereby improving the patient's comfort, reducing irritation to the gastrointestinal tract caused by the nutrient solution, preventing complications such as diarrhea, and improving the patient's tolerance and therapeutic effect of home enteral nutrition.
[0040] The liquid addition port 121 and the liquid discharge port 122 can both be provided with sealing plugs 123, which can be wooden or rubber stoppers. The liquid addition port 121 can be used to manually add liquid of a corresponding temperature into the temperature-controlled chamber 13. Alternatively, the liquid addition port 121 and the liquid discharge port 122 can be connected to a water pump circulation assembly, which can be used to circulate the liquid in the temperature-controlled chamber 13 back and forth multiple times to achieve efficient heat exchange. The outer surface of the nutrient bag 10 is provided with a first scale mark 17.
[0041] In some embodiments, the enteral nutrition delivery device 100 also includes a display component 30, which includes a controller 31, a display 32 and a temperature sensor 33. The temperature sensor 33 is arranged in the first bag body 11 or at the first liquid outlet pipe 15, and is used to detect the real-time temperature of the nutrient solution in the nutrient bag 10; the controller 31 is integrated in the display 32, and the display 32 has a power supply component for providing electrical energy (not shown in the figure). The display 32 is arranged on the front side of the nutrient bag 10, and is used to display the temperature information of the nutrient solution in the nutrient bag 10. The temperature sensor 33 and the display 32 are both electrically connected to the controller 31. Through the setting of the display component 30, the display component 30 includes a controller 31, a display 32 and a temperature sensor 33. The temperature sensor 33 can detect the temperature of the nutrient solution in the nutrient bag 10. The temperature information detected by the temperature sensor 33 can be displayed in real time on the display 32, so that the user can know at any time whether the temperature of the nutrient solution reaches the required temperature according to the display 32. When the temperature of the nutrient solution reaches the required temperature, the user can replenish the nutrient solution to the patient in time without manually measuring the temperature of the nutrient solution. The operation is more convenient, which reduces the user's workload and saves manpower and time.
[0042] The temperature sensor 33 (temperature transducer) is a sensor that senses temperature and converts it into a usable output signal. Temperature sensors are the core component of temperature measuring instruments and come in a wide variety. They can be categorized by measurement method: contact and non-contact. They can also be divided into RTDs and thermocouples based on sensor material and electronic component characteristics.
[0043] Controller 31 is a PLC. A controller is a master device that controls the starting, speed regulation, braking, and reversing of a motor by changing the wiring of the main or control circuits and the resistance values in a predetermined sequence. It consists of a program counter, an instruction register, an instruction decoder, a timing generator, and an operation controller 31. It is the "decision-making body" that issues commands, effectively coordinating and directing the operations of the entire computer system. Controller 31 can be a single-chip microcomputer.
[0044] In some embodiments, the display assembly 30 further includes a liquid level sensor 34, which is disposed within the nutrient bag 10 and is used to detect the liquid level of the nutrient solution within the nutrient bag 10. By configuring the liquid level sensor 34, the liquid level within the nutrient bag 10 can be detected by the liquid level sensor 34. When the remaining nutrient solution within the nutrient bag 10 is low, the user can replenish or stop the nutrient solution delivery in a timely manner according to the actual situation.
[0045] In some embodiments, the enteral nutrition delivery device 100 further includes a heating element 35 disposed within the temperature-controlled chamber 13 for heating the liquid within the chamber. The heating element 35 is electrically connected to a controller 31, which controls the heating element 35 based on temperature information fed back by the temperature sensor 33 to maintain the temperature of the nutrient solution within the nutrient bag 10 at a preset temperature. The display 32 includes a control button 322 and a display screen 321. The control button 322 is used to input preset information to the controller 31, and the display screen 321 is used to display information about the nutrient solution within the nutrient bag 10. To better control the temperature of the nutrient bag 10, the heating element 35 is disposed within the temperature-controlled chamber 13. The heating element 35 can actively heat the liquid within the chamber 13 and transfer heat through the liquid medium, thereby controlling the temperature of the nutrient solution within the first bag body 11. Once the heating element 35 heats the nutrient solution to a preset temperature, the controller 31 automatically controls the heating element 35 to maintain the temperature of the nutrient solution at the preset temperature, achieving constant-temperature infusion of the nutrient solution. Through the control button 322 on the display 32, parameters can be pre-input into the controller 31, and a preset temperature value of the nutrient solution can be selected to meet the needs of different patients and have a wider range of applications.
[0046] The preset temperature may be 35°C-40°C, preferably, the preset temperature is 35°C-37°C, that is, the temperature of the nutrient solution is ensured to be maintained at 35°C-37°C.
[0047] The heating element 35 can have various structures, for example, the heating element 35 can be infrared heating, electric heating wire or heating rod, etc. Optionally, the heating element 35 is an electric heating wire, which is distributed in the temperature control cavity 13 and connected to the power supply component. The working principle of the electric heating wire is the same as that of a common electric kettle and hot water rod, and the electric heating wire is directly in contact with the water to heat it.
[0048] In some embodiments, the display assembly 30 further includes a reminder 36 electrically connected to the controller 31. When the temperature of the nutrient solution in the nutrient bag 10, as detected by the temperature sensor 33, reaches a preset temperature; and / or when the level of the nutrient solution in the nutrient bag 10 falls below a threshold, the controller 31 controls the reminder 36 to issue a reminder signal. The integrated reminder 36 on the display 32 can serve as a reminder. When the temperature of the nutrient solution in the nutrient bag 10, as detected by the temperature sensor 33, reaches a preset temperature, indicating that the nutrient solution has reached an appropriate temperature, the reminder 36 issues a reminder message, prompting the user to administer the nutrient solution to the patient. Similarly, when the remaining nutrient solution in the nutrient bag 10 is insufficient, the reminder 36 can also issue a reminder message, prompting the user to take timely action, such as adding nutrient solution or stopping the infusion. This configuration of the reminder 36 provides both reminders and oversight, eliminating the need for the user to be physically present at the patient's side, thus saving manpower.
[0049] The indicator 36 may be a speaker. When the temperature of the nutrient solution in the nutrient bag 10 detected by the temperature sensor 33 reaches a preset temperature, indicating that the nutrient solution has reached an appropriate temperature, the speaker may emit a "beep beep," "click clack," or "beep beep" sound. If the temperature of the nutrient solution in the nutrient bag 10 detected by the temperature sensor 33 exceeds a preset temperature, such as in the event of a temperature abnormality or mechanical failure, the indicator 36 may emit an over-limit alarm sound, such as a "wail wail" sound. The alarm tone may be user-selectable. If the remaining nutrient solution in the nutrient bag 10 is insufficient, the speaker may repeatedly emit a "low remaining" sound.
[0050] In some embodiments, the display assembly 30 further includes a wireless communication unit 37, and the controller 31 transmits data to the control terminal via the wireless communication unit 37. Through the provision of the wireless communication unit 37, information about the nutrient solution in the nutrient bag 10 can be transmitted to the control terminal in real time via the wireless communication unit 37. Authorized users of the control terminal can be informed of the real-time information about the nutrient bag 10, thereby facilitating remote management by authorized personnel via the network, thereby improving convenience.
[0051] For example, the control terminal can be a mobile phone application, allowing the user to view the real-time status of the nutrition bag 10 on their phone. For example, while the user is doing other things at home, such as cooking, the user can check the status of the nutrition bag 10 through the mobile phone application, without having to go back and forth to the bedroom to check the status of the nutrition bag 10. The wireless communication unit 37 can include one or more of WIFI and 4G networks.
[0052] In some embodiments, a three-way connector 40 is provided at one end of the infusion tube 20 near the first liquid outlet tube 15 of the nutrient bag 10. The three-way connector 40 has a first end 41, a second end 42, and a third end 43 arranged in a Y-shape. The first end 41 is used to communicate with the first liquid outlet tube 15 of the nutrient bag 10, the second end 42 is used to communicate with the second liquid outlet tube 51 of the functional bag 50, and the third end 43 is connected to the infusion tube 20. By connecting the three-way connector 40 to one end of the infusion tube 20, the two ends of the three-way connector 40 can be connected to the nutrient bag 10 and the functional bag 50, respectively. In this way, nutrient solution and cleaning solution can be used alternately. By adjusting the flow regulator 22 on the infusion tube 20, continuous and uniform infusion of enteral nutrition can be provided to the patient, achieving optimal nutrient solution infusion effect. The functional bag 50 stores cleaning liquid or medicine. When it is necessary to flush the infusion tube 20 or administer medicine, the first liquid outlet tube 15 is closed and the second liquid outlet tube 51 is opened. The liquid in the functional bag 50 can flow into the infusion tube 20 through the second liquid outlet tube 51 to achieve the function of administering medicine or flushing. The infusion tube 20 can be cleaned regularly to avoid repeatedly opening the connecting joint between the three-way tube and the first infusion tube, thereby reducing the probability of contaminating the nutrient solution and reducing the user's workload.
[0053] The outer surface of the functional bag 50 is provided with a second scale line 54 .
[0054] In some embodiments, the first liquid outlet pipe 15 is provided with a first movable clamp 60, which is used to control the opening and closing of the first liquid outlet pipe 15. By providing the first movable clamp 60 on the first liquid outlet pipe 15, the first movable clamp 60 can be used to open or close the first liquid outlet pipe 15 to meet different usage scenarios. When delivering nutrient solution, the first movable clamp 60 is opened, so that the nutrient solution in the nutrient bag 10 can be connected to the infusion tube 20 through the first liquid outlet pipe 15. When the infusion tube 20 needs to be cleaned or medication needs to be administered, the first movable clamp 60 can be closed.
[0055] In some embodiments, the second liquid outlet tube 51 is provided with a second movable clamp 61 for controlling the opening and closing of the second liquid outlet tube 51. The second movable clamp 61 allows the second liquid outlet tube 51 to be opened or closed to meet different usage scenarios. When delivering nutrient solution, the first movable clamp 60 is opened and the second movable clamp 61 is closed. When the infusion tube 20 needs to be cleaned or administered, the first movable clamp 60 can be closed and the second movable clamp 61 can be opened.
[0056] The first movable clamp 60 and the second movable clamp 61 may be Robert pipe clamps.
[0057] In some embodiments, the first liquid inlet 14 is provided with a first cover 16, which is provided on the first liquid inlet 14 to seal the opening of the first liquid inlet 14. By providing the first cover 16 on the first liquid inlet 14, the first cover 16 can seal the opening of the first liquid inlet 14, thereby reducing the probability of contamination of the nutrient solution.
[0058] The first cover 16 and the first liquid inlet 14 may be threadedly matched, the inner peripheral wall of the first cover 16 is provided with an internal thread, and the outer wall of the first liquid inlet 14 is provided with an external thread.
[0059] In some embodiments, a second liquid inlet 52 is provided at the top of the functional bag 50. The second liquid inlet 52 is provided with a second cover 53. The second cover 53 is provided to cover the second liquid inlet 52 to seal the opening of the second liquid inlet 52. The second cover 53 can seal the opening of the second liquid inlet 52, reducing the probability of contamination of the liquid stored in the functional bag 50. The second cover 53 and the second liquid inlet 52 can be threaded together, with the inner peripheral wall of the second cover 53 provided with internal threads and the outer wall of the second liquid inlet 52 provided with external threads.
[0060] In some embodiments, a connecting portion 44 is provided at both the first end 41 and the second end 42 , and the connecting portion 44 is used to detachably connect the first liquid outlet pipe 15 to the first end 41 , and detachably connect the second liquid outlet pipe 51 to the second end 42 .
[0061] The connecting portion 44 may be a rubber sleeve. The outer circumferential walls of the first and second ends 41, 42 are provided with grooves 442 corresponding to the position of the connecting portion 44. The rubber sleeve fits over the grooves 442 on the outer circumferential wall of either the first or second end 41, 42. Multiple raised rings 441 are spaced apart along the axial direction of the rubber sleeve. The surfaces of the raised rings 441 protrude from the outer circumferential surface of the tee 40. Taking the connecting portion 44 at the first end 41 as an example, the diameter of the open end of the tee 40 gradually decreases from the grooves 442 toward the first end 41, forming a tapered surface. Specifically, the opening at the first end 41 is relatively small, while the outer diameter of the tee gradually increases from the first end 41 toward the grooves 442. This facilitates insertion of the tee into the first liquid inlet pipe. The raised rings 441 compressively contact the inner wall of the first liquid inlet pipe, deforming the raised rings 441. Frictionally, this secures the tee 40 to the first liquid inlet pipe.
[0062] Of course, the connecting portion 44 on the second end 42 has the same structure, which will not be described in detail here.
[0063] It should be noted that, unless there is any conflict, the features in the embodiments of this application can be combined with each other.
[0064] The above description is merely a preferred embodiment of the present application and is not intended to limit the present application. Various modifications and variations are possible for those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present application shall be included within the scope of protection of the present application.
