Description

Technical Field

[0001] This invention relates to the field of enteral nutrition technology, and in particular to an enteral nutrition infusion device and method with adjustable nutrient ratios. Background Technology

[0002] Enteral nutrition support is one of the core means of treatment and rehabilitation for critically ill patients, postoperative patients, and other groups.

[0014] A method for enteral nutrition administration with adjustable nutrient ratios, comprising the following steps: S1. Prepare the nutritional solution according to the patient's condition; S2. Place the corresponding required nutrient concentrate bottle onto the connecting assembly, and then install the connecting assembly onto the cover plate so that the connecting assembly connects with the injection tube. S3. The control panel controls the start of the injection component, which delivers nutrients from the nutrient solution bottle to the mixing component. S4. The mixing component stirs and mixes various nutrients in the mixing component to form a nutrient solution suitable for the patient.

Once the prepared nutrient solution meets the patient's needs, the nutrient solution in the mixing unit is pumped out through the output pump and delivered into the patient's body. S6. During the infusion of nutrient solution, assess the patient's enteral nutrition tolerance at appropriate times, and dynamically adjust the nutrient ratio and pump speed based on the assessment results.

[0015] Compared with the prior art, the present invention has the following beneficial technical effects: In this invention, the delivery volume of different nutrients can be precisely controlled through the communication connection between the injection component and the control panel; in conjunction with the AI ​​nutrient recommendation combination table and the real-time monitoring of the nutrient solution composition by the detection sensor, the input ratio of liquid and powdered nutrients can be dynamically adjusted to ensure that the weights of nutrients such as energy, protein, and fat meet the needs of the patient's condition, thus solving the problem of ratio deviation in traditional devices.

[0016] The mixing component adopts a non-contact magnetic drive design. The drive motor drives the magnetic rod inside the inner tank to rotate through the magnet and rotating frame, eliminating the dead corners of the mixing and enabling uniform mixing of nutrients, especially powder and liquid.

[0018] The control panel has multi-directional communication connections with the detection sensors, output pump, injection components, and heating components, forming an integrated monitoring-control-infusion mechanism: the detection sensors collect nutrient solution composition and temperature data in real time and feed them back to the control panel, which can automatically adjust the speed of the servo motor, the temperature of the heating components, and the infusion speed of the output pump without manual intervention, thus improving the efficiency and accuracy of regulation.

[0019] By combining the enteral nutrition tolerance scoring mechanism, the control panel can dynamically adjust the proportion of various nutrients delivered by the infusion component and the infusion rate of the output pump based on the total score of three types of symptoms: abdominal distension / abdominal pain, nausea / vomiting (including gastric residual volume) and diarrhea. For example, when the total score is ≤2, the infusion rate is increased or the nutrient density is increased; when the total score is 3-4, the rate is slowed down; and when the total score is ≥5, the infusion is paused. This achieves individualized dynamic optimization of the nutrition plan and significantly reduces the incidence of gastrointestinal adverse reactions.

[0020] The modular design with multiple injection fittings and connecting components allows for simultaneous adaptation to both liquid and powdered nutrient containers, and compatibility with commercially available nutritional products of different specifications. The inner liner of the mixing component and the magnetic stirring structure of the stirring component can meet the mixing needs of various nutrients, making it suitable for different patient groups such as critically ill patients, postoperative rehabilitation patients, and elderly patients with multiple comorbidities, with extremely strong clinical applicability.

[0025] Many specific details are set forth in the following description in order to provide a full understanding of the invention.

Therefore, the invention is not limited to the specific embodiments disclosed below.

[0027] Secondly, the present invention is described in detail with reference to the schematic diagrams. When detailing the embodiments of the present invention, for ease of explanation, the cross-sectional views illustrating the device structure may be partially enlarged, not according to the usual scale. Furthermore, the schematic diagrams are merely examples and should not limit the scope of protection of the present invention. In addition, actual fabrication should include three-dimensional spatial dimensions of length, width, and depth.

[0028] Example 1 like Figure 1-9As shown, the present invention proposes an enteral nutrition infusion device with adjustable nutrient ratio, comprising a mixing component 1, a stirring component 2, an injection tube 3, an injection component 4, a connecting component 5, a snap-fit ​​component 6, an output pump 8, a detection sensor 9, and a control panel 10. The mixing assembly 1 includes a mixing tank 101, a cover plate 102 disposed on the mixing tank 101, a magnetic suction column 103 disposed on the cover plate 102 and magnetically connected to the mixing tank 101, an inner liner 104 disposed inside the mixing tank 101, and a heating assembly 105 disposed on the inner liner 104. The volume of the inner liner 104 is 2-3L. A stirring assembly 2 is disposed inside the mixing tank 101 with its output end located inside the inner liner 104; multiple injection pipes 3 are disposed on the cover plate 102; multiple injection assemblies 4 are disposed within the injection pipes 3 respectively; multiple connecting assemblies 5 are disposed on the injection pipes 3 and detachably connected to the cover plate 102; a snap-fit ​​assembly 6 is disposed on the cover plate 102 and snaps into the connecting assemblies 5; an output pump 8 is disposed on the cover plate 102 with its input end located inside the inner liner 104; a detection sensor 9 is disposed on the cover plate 102 with its detection end located inside the inner liner 104; a control panel 10 is disposed on the cover plate 102 and is communicatively connected to the detection sensor 9 and the output pump 8, and the control panel 10 is controllably connected to the injection assemblies 4.

[0029] In this embodiment, the delivery amount of different nutrients can be precisely controlled through the communication connection between the injection component 4 and the control panel 10. With the help of the AI ​​nutrient recommendation combination table and the detection sensor 9 for real-time monitoring of the nutrient solution composition, the input ratio of liquid and powdered nutrients can be dynamically adjusted to ensure that the weights of nutrients such as energy, protein, and fat meet the needs of the patient's condition, thus solving the problem of ratio deviation in traditional devices.

[0030] The stirring component 2 adopts a non-contact magnetic drive design. The drive motor 204 drives the magnetic rod 201 inside the inner liner 104 to rotate through the magnet 203 and the rotating frame 202. There are no dead corners in the stirring, which can achieve uniform stirring of nutrients, especially powder and liquid. The inner liner 104 of the mixing component 1, together with the heating component 105, can accurately control the temperature of the nutrient solution, avoid the inactivation of nutrients, and improve the acceptance of the nutrient solution by the patient's gastrointestinal tract.

[0031] The design of the connecting component 5 and the snap-fit ​​component 6 allows for quick assembly and disassembly of the injection tube 3 and the cover plate 102 without the need for additional wiring; the pushing component 7 drives the sliding sleeve 502 to move, so that the threaded connection port 503 and the injection groove 5011 are precisely connected and sealed, effectively preventing nutrient solution leakage and external contamination, and greatly simplifying the operation process for medical staff.

[0032] The control panel 10 has multi-directional communication connections with the detection sensor 9, output pump 8, injection component 4, and heating component 105, constructing an integrated monitoring-control-injection mechanism. The detection sensor 9 uses an infrared spectroscopy sensor. Near-infrared spectroscopy is a method to analyze the nutritional components of food through infrared light radiation technology. Its principle is to detect the chemical characteristics of the reflected and transmitted light spectra of food by performing spectral detection on the food to obtain the content of the nutritional components of the food. It also collects the nutrient solution composition and temperature data in real time and feeds them back to the control panel 10. The control panel 10 can automatically adjust the speed of the servo motor 402, the temperature of the heating component 105, and the injection speed of the output pump 8 without manual intervention, thus improving the efficiency and accuracy of regulation.

[0033] By combining the enteral nutrition tolerance scoring mechanism, the control panel 10 can dynamically adjust the delivery ratio of the infusion component 4 and the infusion rate of the output pump 8 based on the total score of three types of symptoms: abdominal distension / abdominal pain, nausea / vomiting (including gastric residual volume) and diarrhea. For example, when the total score is ≤2 points, the infusion rate is maintained / increased; when the total score is 3-4 points, the rate is slowed down; and when the total score is ≥5 points, the infusion is paused. This achieves individualized dynamic optimization of the nutrition plan and significantly reduces the incidence of gastrointestinal adverse reactions.

[0034] The injection fitting 3 is set with multiple components and has a modular design that works in conjunction with the connecting component 5. It can be adapted to both liquid and powdered nutrient containers and is compatible with commercially available nutrient products of different specifications. The inner liner 104 of the mixing component 1 and the magnetic stirring structure of the stirring component 2 can meet the mixing needs of various nutrients. It is suitable for different patient groups such as critically ill patients, postoperative rehabilitation patients, and elderly patients with multiple complications, and has strong clinical applicability.

[0035] Example 2 like Figure 1-9 As shown, the enteral nutrition infusion device with adjustable nutrient ratio proposed in this invention, compared with Embodiment 1, the stirring assembly 2 in this embodiment includes a drive motor 204 disposed in the mixing tank 101, a magnet 203 disposed on the output end of the drive motor 204, a rotating frame 202 disposed on the magnet 203 and having multiple rotating frames disposed on the magnet 203, and a magnetic suction rod 201 slidably disposed in the inner liner 104 and magnetically connected to the rotating frame 202.

[0036] In this embodiment, the drive motor 204 drives the magnet 203 to rotate, the magnet 203 drives the rotating frame 202 to move, and the rotating frame 202 drives the magnetic suction rod 201 to rotate through magnetic force, so that the magnetic suction rod 201 can rotate inside the inner liner 104, thereby mixing and stirring the nutrients inside the inner liner 104. The heating component 105 heats the nutrients, thereby forming a nutrient solution that meets the needs of the patient's body. During use, the magnetic suction rod 201 rotates continuously at a uniform speed to prevent the substances inside the inner liner 104 from precipitating out.

[0037] Example 3 like Figure 1-9 As shown, the present invention proposes an enteral nutrition infusion device with adjustable nutrient ratio. Compared with Embodiment 1 or Embodiment 2, the cover plate 102 in this embodiment is provided with a connecting groove 1021; the injection pipe 3 includes a support base 302 disposed in the connecting groove 1021, a closing pipe 301 disposed on the support base 302, and a discharge pipe 303 disposed at the end of the closing pipe 301 and communicating with the cover plate 102.

[0038] The injection assembly 4 includes a spiral conveyor 401 rotatably disposed within the converging tube 301, a servo motor 402 disposed on the connecting assembly 5 and connected at its output end to the spiral conveyor 401, a sealing plug 403 slidably disposed within the discharge tube 303 and capable of being sealed, and an elastic member 404 disposed on the discharge tube 303 for pushing the sealing plug 403 to move.

[0039] The connecting assembly 5 includes a second support base 505 slidably disposed within the connecting groove 1021, a connecting pipe 501 disposed on the second support base 505, a sliding sleeve 502 slidably disposed on the connecting pipe 501, a threaded connection port 503 disposed on the sliding sleeve 502, and an elastic element 504 disposed on the connecting pipe 501 for pushing the sliding sleeve 502 to move; both the connecting pipe 501 and the sliding sleeve 502 are provided with an injection groove 5011 communicating with the threaded connection port 503; and the closing pipe 301 is provided with a pushing assembly 7 for pushing the sliding sleeve 502 to move.

[0040] The snap-fit ​​assembly 6 includes a support rod 603 disposed on the cover plate 102, a sliding rod 602 slidably disposed on the support rod 603, an elastic element 604 disposed on the support rod 603 for pushing the sliding rod 602 to move, and a snap-fit ​​post 601 disposed on the sliding rod 602 and snap-fitted with the support base 505.

[0041] The pushing component 7 includes a guide rod 701 disposed on the constricting tube 301, a limiting block 702 disposed on the guide rod 701, an elastic element 703 disposed on the limiting block 702, and a connecting seat 704 disposed on the sliding sleeve 502 and slidably connected to the guide rod 701 and abutting against the elastic element 703.

[0042] The output end of the servo motor 402 is provided with a connector, and the spiral conveyor 401 is provided with a connecting groove, into which the connector can be embedded. A connection point is provided at the connection between the cover plate 102 and the second support base 505. The control panel 10 is electrically connected to the second support base 505 through the connection point, and the connection point is electrically connected to the servo motor 402. The second support base 505 can be automatically electrically connected to the magnetic rod 201 via the connection point, requiring no additional wiring and making operation convenient.

[0043] In this embodiment, pulling down the sliding rod 602 causes the locking post 601 to move, separating the locking post 601 from the second support base 505. This allows the second support base 505 to move out of the connecting groove 1021, thus enabling the connection assembly 5 to be disassembled. When the connection assembly 5 is disassembled, the second elastic element 504 pushes the sliding sleeve 502 to move, which in turn moves the threaded connection port 503. This causes the threaded connection port 503 to misalign with the injection groove 5011 on the connecting tube 501, creating a sealing effect. The bottle containing the required nutrients is then inverted and installed onto the threaded connection port 503. The second support base 505 is then aligned with the connecting groove 1021, and the connecting tube 501 is aligned with the closing tube 301. This pushes the second support base 505 onto the magnetic rod 201, and the locking assembly 6 holds the second support base 505 in place, allowing the connection assembly 5 to dock with the injection tube 3.

[0044] When the connecting component 5 is connected to the injection pipe 3, the guide rod 701 is aligned with the connecting seat 704, and the limiting block 702 supports the elastic element 703. The elastic element 703 pushes the connecting seat 704 to move, the connecting seat 704 drives the sliding sleeve 502 to move, the sliding sleeve 502 drives the threaded connection port 503 to move, and the threaded connection port 503 is connected to the injection groove 5011, so that the nutrients in the nutrient raw material bottle can fall into the connecting pipe 501.

[0045] The servo motor 402 drives the screw conveyor 401 to rotate, which conveys nutrients to the sealing plug 403 and squeezes it. The sealing plug 403 overcomes the elastic force of the elastic element 404 and moves, allowing the nutrients to fall into the inner liner 104 through the feed pipe 303. It can then mix with other nutrients to prepare a nutrient solution. At the same time, the input ratio of different nutrients is adjusted in real time according to the detection results of the detection sensor 9, so as to prepare a nutrient solution suitable for the patient's physical condition.

[0046] Example 4 like Figure 1-9 As shown, the present invention proposes an enteral nutrition infusion method with adjustable nutrient ratios, which includes the following steps: S1. Prepare the nutritional solution according to the patient's condition; S2. Place the corresponding required nutrient stock solution bottle onto the connecting component 5, and then install the connecting component 5 onto the cover plate 102 so that the connecting component 5 is connected to the injection tube 3. S3. Control panel 10 controls the injection component 4 to start, and injection component 4 delivers nutrients from the nutrient solution bottle to mixing component 1. S4. The various nutrients in the mixing component 1 are stirred and mixed by the stirring component 2 to form a nutrient solution that can be adapted to the patient. The composition and temperature of the nutrient solution are monitored in real time by the detection sensor 9. S5. Once the prepared nutrient solution meets the patient's needs, the nutrient solution in the mixing component 1 is pumped out by the output pump 8 and delivered to the patient's body. S6. During the infusion of nutrient solution, assess the patient's enteral nutrition tolerance at appropriate times, and dynamically adjust the nutrient ratio and pump speed based on the assessment results.

[0047] In this embodiment, nutrients are divided into two main categories: liquid nutrients and powdered nutrients. Since the packaging of each nutrient varies in actual use (e.g., bags, bottles, drums), a 500ml container is used uniformly. This container must be compatible with the threaded connection port 503. Purified water also occupies one threaded connection port 503. During preparation, water is automatically added. After the container is installed, the corresponding substance number is entered into the control panel 10. The control panel 10 has a database that can retrieve the substance composition based on the substance number. During preparation, different categories of nutrients are input into the inner liner 104, and water is added. After stirring, a new nutrient solution is formed. The detection sensor 9 can detect the content of core nutrients such as carbohydrates, proteins, fats, and electrolytes, as well as important parameters such as temperature, flow rate, and energy. According to the different disease needs of different patients, the types and amounts of nutrients required are adjusted. The types and components of nutrients are made into a nutrient database. When using it, after inputting the nutrient components required by the patient's body, the AI ​​will provide a nutrient recommendation combination table. Medical staff can select appropriate nutrient categories based on the nutrient recommendation combination table and clinical experience, and install them on the connecting component 5 for automatic nutrient preparation. The detection sensor 9 then detects the nutrient solution to determine whether it meets the requirements.

[0048] The table below shows the nutritional components required for some diseases: Three types of gastrointestinal adverse reactions were scored after use, as shown in the table below: Individualized enteral nutrition for heart failure patients The patient, a 68-year-old male, was diagnosed with ischemic cardiomyopathy, NYHA functional class IV, and was in the acute phase of heart failure. According to the "Guidelines for Emergency Management of Acute Heart Failure in China (2022)" and the "Guidelines for Nutritional Support for Critically Ill Patients (2024)," the total 24-hour fluid intake limit for this patient was set at 1000 mL. Nutritional assessment: The patient is 172 cm tall and weighs 60 kg. His recent food intake has significantly decreased by 50%. Gastrointestinal function assessment is normal. His NRS-2002 nutritional risk screening score is 5, and his SGA assessment indicates moderate malnutrition, necessitating immediate initiation of enteral nutritional support.

[0049] The implementation process is as follows: Initial parameter settings and scheme generation: Medical staff input patient information into the device's interactive interface: diagnosis (acute heart failure), NYHA class (Class IV), and fluid restriction (1000 mL / 24 h).

[0050] Based on the above parameters and in accordance with the guidelines, the system generates an initial nutritional support plan: to ensure gastrointestinal adaptability, Ensure nutritional solution with a density of 0.75 kcal / mL is selected in the initial stage. The target energy supply value is set according to the patient's condition. Low-calorie feeding is permitted during the acute phase of the disease. The initial infusion rate is set at 30 mL / h.

[0051] Infusion process and intelligent monitoring: After the device is started, the intelligent infusion control unit begins to work. Sensor 9 confirms in real time that the nutrient solution density matches the set value. After 6 hours of infusion, the patient's gastrointestinal adaptability is assessed, and the subsequent infusion rate is adjusted accordingly.

[0052] If the initial dose is 0.75 kcal / ml, gastrointestinal tolerance is reassessed after 6 hours. If the adaptation is good, the pump rate is increased to 50 ml / h. Fluid volume is continuously assessed during the process. If the remaining fluid volume is less than 200 ml, a fluid volume warning is activated. If the gastrointestinal tolerance is good after reassessment, the density is increased to 1.0 kcal / ml.

[0053] During the infusion process, the device continuously monitors the patient's cumulative infusion volume. Simultaneously, based on preset gastrointestinal tolerance assessment criteria, such as the absence of adverse reaction reports like abdominal distension or diarrhea, the system determines that the patient's gastrointestinal tolerance is good.

[0054] Dynamic adjustment and early warning intervention: When the real-time monitoring shows that the cumulative infusion volume has reached 80% of the preset limit of 1000mL, i.e., 800mL, the device's early warning system is triggered.

[0055] The system issued an audible and visual warning signal and clearly displayed a message on the human-machine interface: The current cumulative infusion volume has reached 800 mL, approaching the 24-hour fluid restriction threshold (1000 mL). Based on gastrointestinal tolerance assessment, the patient is adapting well. Recommendation: Increase the nutrient solution density to 1.0 kcal / mL, which will provide approximately 800 kcal of energy with the same fluid volume, and the supply of key nutrients such as protein will increase accordingly, better meeting the patient's energy needs.

[0056] After confirming the prompt, medical staff can confirm the adjustment of the treatment plan with one click through the interface. The mixing mechanism is activated, and nutrients are added to smoothly transition the nutrient solution density from 0.75 kcal / mL to 1.0 kcal / mL without changing the nutrient solution bag or interrupting the infusion.

[0057] Implementation results: Through the intelligent management of this device, while strictly adhering to the 1000mL fluid restriction, the patient's actual 24-hour energy intake increased from the initial 750kcal to approximately 800kcal, and the infusion rate steadily increased to 50ml / h, thus optimizing energy supply.

[0058] The entire infusion process achieved precise control of the total fluid volume, avoiding the risk of overload; at the same time, the smooth transition of concentration ensured gastrointestinal tolerance and did not cause adverse reactions such as abdominal distension or diarrhea.

[0059] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
