Description

Background Art

[0002] In clinical practice, for patients who cannot eat independently, enteral nutrition infusion has become a key means to maintain the patient's vital activities and promote recovery. At present, enteral nutrition infusion is mainly achieved through pipelines such as gastric tubes, nasogastric tubes and enterostomy tubes, and ensuring that the pipeline is unobstructed and avoiding reflux and blockage depends on regular pipeline flushing. However, the enteral nutrition infusion device in the prior art, such as the automatic tube flushing nutrition infusion pump described in the patent with announcement number CN221106480U, can achieve automatic flushing, but still has significant shortcomings.

[0003] Specifically, the device described in the patent starts the auxiliary nutrition pump through the PLC controller, extracts the flushing fluid and sends it to the main pump, which then enters the nutrition tube through the flushing tube, mixes with the nutrition fluid and increases the pressure in order to solve the blockage problem. However, in actual application environments, nutrition pumps and their key components are often exposed to the outside world due to lack of effective protection, and are susceptible to factors such as dust accumulation and accidental collisions, resulting in equipment performance degradation or even damage, seriously affecting the stability and service life of the infusion device. This not only increases medical costs, but is also likely to interrupt the patient's nutrition supply due to equipment failure, which has an adverse effect on their recovery process.

[0004] For example, the publication number CN221431613U discloses a stomach tube with a built-in anti-reflux structure, which relates to the technical field of stomach tubes. The stomach tube comprises a stomach tube body and an air bag, wherein the air bag is fixedly arranged on the outside of the stomach tube body, a double-forked tube is arranged on the upper end of the stomach tube body, and the upper end of the double-forked tube is connected to a liquid inlet tube and a liquid outlet tube, a catheter head is arranged on the lower end of the stomach tube body, a fixing component is arranged on the outside of the stomach tube body, and an inflation component is arranged inside the stomach tube body, so that the liquid inlet tube can be connected to a nutrient solution pump through a connector, so as to inject the nutrient solution into the patient's stomach. The required nutrient solution or medicine is added, the nutrient solution or medicine enters the liquid inlet tank, and then is injected into the patient's stomach through the liquid inlet hole. At the same time, the doctor can connect the liquid outlet tube to the syringe or other suction device through the connector to draw back the stomach contents to prevent gastric retention. The liquid outlet tank and the liquid inlet tank do not interfere with each other, which makes it convenient to treat patients and prevent cross infection. However, it has a single functionality and does not have an integrated design. It is inconvenient to store and collect nutrient solution bags and flushing solution bags, and it is inconvenient to infuse enteral nutrition.

[0005] At present: In China, the research and application of enteral nutrition infusion pumps have made certain progress. For example, some studies have compared the effects of different infusion methods (such as manual push, gravity drip and infusion pump infusion) on enteral nutrition complications and found that infusion pump infusion can reduce the incidence of complications (such as the study of Liu Ji et al.). In addition, domestic scholars have also paid attention to the shortcomings of enteral nutrition infusion pumps in practical applications, such as the problem that the equipment is easily affected by external factors, resulting in performance degradation or damage. Therefore, some studies are committed to developing enteral nutrition infusion devices with efficient automatic flushing function, excellent protection performance and high stability to meet clinical needs (such as the anti-reflux enteral nutrition infusion pump proposed in this study).

[0006] In foreign countries, the research and application of enteral nutrition infusion pumps are also extensive. For example, the American Society for Enteral and Parenteral Nutrition (ASPEN) and the European Society for Enteral and Parenteral Nutrition (ESPEN) both recommend the use of enteral nutrition infusion pumps for patients who receive enteral nutrition for a long time (2 to 3 weeks or longer) in their guidelines. Foreign scholars have also verified the effectiveness of infusion pumps in reducing enteral nutrition complications (such as diarrhea, vomiting, reflux, and aspiration pneumonia) through prospective randomized crossover studies (such as the study of Shang E et al.). In addition, foreign research also involves technological innovations in enteral nutrition infusion pumps, such as the development of a new generation of infusion pumps that can be "controlled" with artificial intelligence to improve the accuracy and safety of infusion.

[0058] Specifically, the lifting and adjusting mechanism 7 includes two lifting platforms 71 and a power component for driving the two lifting platforms 71 to rise and fall synchronously;

[0059] The power component includes two first shafts and a second shaft rotatably installed in the outer box 1, the two first shafts are each installed with a second main gear 76, and a synchronous belt 77 is also connected between the two first shafts, and the two second shafts are each installed with a sub-gear 75 respectively meshing with the two second main gears 76, and the bottom of the two lifting platforms 71 are symmetrically installed with two tooth plates 72 meshing with the sub-gear 75, and a second motor 78 is also installed inside the outer box 1, and the output end of the second motor 78 is connected to one end of one of the first shafts.

[0066] By adopting the above technical solution:

[0067] When performing enteral nutrition infusion for a patient, the nutrient solution bag 15 and the flushing solution bag 14 can be hung on the hook 33 respectively first, and then the first motor 310 drives the first main gear 39 to rotate, so that the first main gear 39 drives the slave gear 36 meshing with it to rotate, and then the slave gear 36 drives the threaded sleeve 35 to rotate, so that the threaded rod 38 is screwed out of the threaded cavity to drive the vertical rod 31 to rise, so that the nutrient solution bag 15 and the flushing solution bag 14 hung on the vertical rod 31 rise to a suitable height for infusion, and when the infusion is completed, the first main gear 39 can be driven by the first motor 310 to rotate, so that the first main gear 39 drives the slave gear 36 meshing with it to rotate, and then the slave gear 36 drives the threaded sleeve 35 to rotate, so that the threaded rod 38 is screwed out of the threaded cavity, so as to drive the vertical rod 31 to rise, so that the nutrient solution bag 15 and the flushing solution bag 14 hung on the vertical rod 31 rise to a suitable height for infusion, and when the infusion is completed, The first motor 310 drives the first main gear 39 to rotate in the opposite direction, and then the first main gear 39 drives the threaded sleeve 35 to rotate in the opposite direction through the slave gear 36, so that the threaded rod 38 is screwed into the threaded cavity in the threaded sleeve 35, so as to drive the vertical pole 31 to descend, so that the nutrient solution bag 15 and the flushing liquid bag 14 hung on the vertical pole 31 descend, thereby realizing the height adjustment of the infusion structure 3, which not only facilitates the hanging of the nutrient solution bag 15 and the flushing liquid bag 14, but also ensures the infusion of the nutrient solution, improves the practicability of the device, and facilitates the infusion of enteral nutrition.

[0068] Example 3

[0069] like Figure 3 , Figure 4 , Figure 8 and Fig. 9 As shown, two winding tube structures 6 are further provided in the outer box 1, and each winding tube structure 6 includes a support frame 61, and two side plates 62 and a winding tube rod 64 are fixed to the top of the support frame 61, and the two winding tube rods 64 are located between the two side plates 62, and springs 65 are fixed on one side of the two side plates 62 adjacent to the winding tube rod 64, and one end of the spring 65 is connected to a movable clamp 63 that can interfere with the winding tube rod 64.

[0070] By adopting the above technical solution:

[0071] When the device is stored or transported, the nutrient solution tube 13, the flushing tube 12 and the insertion tube 11 can be wound on two relatively winding rods 64, and then the movable splint 63 squeezes the nutrient solution tube 13, the flushing tube 12 and the insertion tube 11 on the winding rod 64 under the action of the spring 65, so as to clamp the nutrient solution tube 13, the flushing tube 12 and the insertion tube 11, thereby achieving stable storage of the nutrient solution tube 13, the flushing tube 12 and the insertion tube 11, which can facilitate the orderly storage of the nutrient solution tube 13, the flushing tube 12 and the insertion tube 11 and facilitate the transportation of the device.

[0072] Furthermore, if Figure 8 and Fig. 9 As shown, the side of the movable clamping plate 63 facing the tube winding rod 64 is provided with arc grooves 68 distributed at equal distances in the vertical direction, and two arc grooves 68 can be combined to form a clamping circular hole. Based on this, when the nutrient solution tube 13, the flushing tube 12 and the insertion tube 11 are wound on the two tube winding rods 64, the clamping circular hole formed by the combination of the arc grooves 68 on the movable clamping plate 63 and the tube winding rod 64 can limit the position of the nutrient solution tube 13, the flushing tube 12 and the insertion tube 11, so as to ensure the stable winding of the nutrient solution tube 13, the flushing tube 12 and the insertion tube 11, and further facilitate the storage of the nutrient solution tube 13, the flushing tube 12 and the insertion tube 11.

Based on this, when the spring 65 drives the movable splint 63 to move, the movable splint 63 can drive the slider 66 at its bottom to slide along the slide groove 67 to limit the movable splint 63, thereby realizing the stable movement of the movable splint 63, which can facilitate the stable clamping of the nutrient solution tube 13, the flushing tube 12 and the insertion tube 11 by the movable splint 63.

[0074] Technical Field Please explain in detail what this pump does

[0075] The pump of the present invention is specifically an integrated nutrition infusion component. The pump can stably pump the nutrient solution from the nutrient solution bag into the patient's intestine to ensure that the patient obtains the necessary nutritional support, which is particularly important for patients who cannot eat independently. The built-in flushing component of the pump can increase the pressure in the pipeline when necessary to prevent the reflux in the patient's intestine from flowing back into the infusion system, thereby avoiding possible infection or blockage risks and ensuring the smoothness and safety of the infusion process. Through the design of the movable outer box and the lifting and adjusting mechanism, the pump is not only easy to move and use between different medical environments, but also can easily store the infusion components when not needed, reducing the risk of equipment damage and extending the service life. At the same time, the design of the box cover also provides additional protection for the equipment. At the same time, the height adjustability of the integrated design infusion structure enables the nutrient solution bag and the flushing solution bag to be suspended at a suitable height, which is convenient for medical staff to operate. In addition, the setting of the winding structure enables various pipelines to be stored and fixed in an orderly manner, further improving the convenience and safety of operation.

[0076] Please explain in detail how this reflux is used, what are the potential complications, what are the advantages compared with conventional methods, and why it is designed this way.

[0077] During the process of enteral nutrition infusion, reflux of nutrient solution or gastric contents may occur due to various factors such as the patient's physiological condition, infusion speed, and pipe position. The flushing component in the present invention can effectively re-infuse the refluxed refluxed material into the intestine by increasing the pressure of the pipe in the nutrition infusion component, thereby avoiding complications such as infection and aspiration pneumonia caused by the refluxed material, and ensuring the safety and effectiveness of the infusion.

[0078] Potential complications: Aspiration pneumonia: Refluxed material is inhaled into the lungs by mistake, leading to lung infection. Infection: Refluxed material is retained in the pipes, becoming a breeding ground for bacteria, increasing the risk of infection. Poor nutrient absorption: Reflux causes the nutrient solution to fail to effectively enter the intestines, affecting the patient's nutrient absorption.

[0079] Comparison with conventional designs

[0080] Conventional design:

[0081] Insufficient protection performance, the equipment is easily affected by external factors, resulting in performance degradation or damage. Single functionality, lack of integrated design, inconvenient storage of nutrient solution bags and flushing solution bags. Improper reflux treatment can easily lead to complications.

[0082] The design of the present invention: Enhanced protection performance: The design of the outer box and the box cover provides effective protection for the equipment to prevent dust accumulation, accidental collisions and other factors from affecting the performance of the equipment. Integrated design: The infusion structure, nutrition infusion components, flushing components and lifting and adjusting mechanisms are integrated into one, which is convenient for storage, storage and transportation, and improves the portability and practicality of the equipment. Proper reflux treatment: The design of the flushing component can effectively deal with the reflux problem and reduce the incidence of complications.

[0083] Design reason: Considering that the enteral nutrition infusion pump is easily affected by external factors in the actual application environment, the present invention provides comprehensive protection for the equipment by designing a removable outer box and box cover, thereby extending the service life of the equipment and ensuring the stability and safety of the infusion.

[0084] Integrated design: In order to meet clinical needs, the present invention integrates the infusion structure, nutrition infusion components, flushing components, and lifting and adjusting mechanisms into one, achieving a high degree of integration of the equipment, which is convenient for medical staff to operate and manage.

[0085] Reflux treatment: To address the reflux problem, the present invention innovatively designs a flushing component that increases pipeline pressure to re-inject refluxed materials into the intestine, effectively avoiding complications caused by reflux.

[0086] Humanized design: The design of the lifting and adjusting mechanism enables the height of the equipment to be adjusted according to the actual situation, which is convenient for medical staff to operate; the setting of the pipe winding structure facilitates the orderly storage and transportation of the pipes, improving the portability of the equipment.

[0087] In summary, the anti-reflux enteral nutrition infusion pump provided by the present invention is superior to conventional designs in terms of protection performance, integrated design, reflux treatment and humanized design, and can effectively solve the deficiencies in the existing technology, meet clinical needs and improve the patient's rehabilitation quality.

[0088] What is the design concept and what is the specific basis

[0089] People-oriented: meet people's needs: this design aims to meet the nutritional needs of patients who cannot eat independently, maintain their life activities through enteral nutrition infusion, and promote recovery. Consider human behavior and psychology: the design takes into account the operating habits and psychological needs of medical staff, and improves the ease of use and convenience of the equipment through integrated design and humanized operation interface.
