Description

Technical Field

[0001] This invention relates to the field of feeding device technology, specifically to a liquid food and medication feeding device for gastroenterology. Background Technology

[0002] Gastroenterology feeding devices for liquid food and medication are medical assistive devices specifically designed for clinical nursing in gastroenterology. They are mainly used for patients who cannot eat normally orally, have difficulty swallowing, or require tube feeding. They deliver liquid food, nutritional solutions, and medications accurately and safely through tubes such as nasogastric tubes and gastric tubes. The infusion rate and dosage can be precisely controlled to avoid choking, aspiration, and tube blockage. Made of safe and compliant materials, they are easy to operate and can effectively ensure the patient's nutritional supply and standardized medication administration, improve nursing efficiency and patient comfort. They are commonly used nursing tools for postoperative, critically ill, and long-term tube-fed patients in gastroenterology.

[0003] The core working principle of the pistol-type liquid food and medication feeder used in gastroenterology is to manually push and pull the piston rod on the gun handle, causing the piston in the liquid storage chamber to reciprocate. When the push rod is pushed forward, the piston creates positive pressure on the liquid food or medication in the chamber, accurately delivering it to the patient's gastrointestinal tract through the front connector and nasogastric tube. When the push rod is pulled backward, the piston moves backward, creating negative pressure, which can draw liquid food or medication from the container to complete the filling. The entire process can be manually controlled in terms of pushing speed and dosage to avoid aspiration and tube blockage, ensuring tube feeding safety.

[0004] Existing gastroenterology feeding devices for liquid food and medication still require users to manually push and pull the piston rod on the handle. Prolonged operation can easily lead to arm muscle fatigue, significantly reducing the user experience. Secondly, during feeding, especially in winter, the temperature of liquid food drops rapidly, which can easily cause abdominal discomfort or physical discomfort to the user, thereby reducing the practicality and clinical application value of the product. Summary of the Invention

[0005] Based on this, the purpose of the present invention is to provide a liquid food and drug feeder for gastroenterology, so as to solve the technical problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a liquid food and drug feeder for gastroenterology, comprising a handle, wherein the handle has a built-in battery and an electric push rod is fixedly installed on the top of the handle, the output end of the electric push rod is connected to the piston assembly of the feeding tube, a positioning ring is connected to one side of the handle, and a support frame is movably sleeved on the inner wall of the positioning ring, a limit block is movably connected to the inner wall of the support frame, and a button is provided on the handle, and the button is electrically connected to the electric push rod.

[0007] By adopting the above technical solution, the positioning ring and the support frame are set. The support frame is movably fitted on the inner wall of the positioning ring, and one end of the support frame is equipped with a spring and a connecting rod, which effectively limits the position of the support frame. Secondly, the inner wall of the support frame is equipped with a food container. The position of the food container is effectively limited by the engagement of the first groove and the protrusion, which reduces the displacement of the food container and improves the practicality of the product. By setting the limiting block, the inner wall of the support frame is equipped with a limiting block, and the limiting block is movably connected to the inner wall of the support frame. Moving the limiting block makes the two sets of limiting blocks engage, and the limiting block is located on the outer wall of the food container. The support frame and the limiting block heat the food container from multiple angles, which improves the practicality of the product. Especially in winter, the support frame and the limiting block keep the food container warm, which greatly reduces the phenomenon of rapid temperature drop of liquid food and is less likely to cause abdominal discomfort or physical discomfort to the consumer.

[0008] The present invention is further configured such that the outer wall of the feeding tube is threadedly connected to the inner ring of the positioning ring.

[0009] As a preferred option, the threaded connection structure is simple and reliable, effectively fixing the feeding tube and preventing it from loosening or shifting during the pushing process.

[0012] The present invention is further configured such that a spring is provided at one end of the fixing ring, and a connecting rod is sleeved on the inner wall of the spring, and the end of the connecting rod away from the spring is fixedly connected to the support frame.

[0013] Preferably, the cooperation between the spring and the connecting rod can elastically limit the movement of the support frame, preventing excessive movement that could damage the components. The elastic limiting structure can buffer the impact force during the pushing process, protecting the food container and the liquid food inside from severe compression.

[0014] The present invention is further configured such that a second groove is provided on the inner wall of the support frame, a slider is connected to one side of the limiting block, the slider slides in cooperation with the second groove, and a third groove is provided at one end of the slider.

[0015] Preferably, the position adjustment of the limiting block is more flexible and can be adapted to different sizes of food containers. The setting of the third groove can lock the position of the slider (the two ends of the slider are magnetically attracted after being engaged by the setting of the third groove), preventing the limiting block from shifting during operation and improving the stability of heat preservation.

[0016] The present invention is further configured such that the limiting block and the support bracket have a built-in heating module, and the heating module is electrically connected to the button.

[0017] Preferably, the heating module built into the limiting block and the support frame can heat the feeding tube from multiple angles, ensuring uniform temperature of liquid food and improving the heat preservation effect. The heating module is electrically connected to the button, which makes it easy for caregivers to control the heating status in real time, improving the convenience and safety of operation.

[0018] The present invention is further configured such that a fixing block is provided between the connecting rod and the support frame, and the fixing block is movably sleeved on the outer wall of the connecting rod.

[0019] Preferably, the connection strength between the connecting rod and the support frame is enhanced, improving the overall structural stability of the device. The fixing block is movably sleeved on the outer wall of the connecting rod, which can help guide the movement direction of the connecting rod.

[0020] The present invention is further configured such that the battery is electrically connected to the electric push rod and the heating module, and a round hole is provided at one end of the support frame.

[0021] Preferably, the battery provides unified power to the electric push rod and heating module, which simplifies the circuit structure of the device and improves energy utilization efficiency. The round hole at one end of the support frame facilitates precise docking of the feeding tube and the nasogastric tube.

[0022] The present invention is further configured such that the inner wall of the positioning ring has a through hole, and a support bracket is placed in the through hole.

[0023] Preferably, a stable moving channel is provided for the support bracket to ensure that it maintains linear movement during the pushing process. The through holes can guide the support bracket to prevent it from deviating or getting stuck, thus improving the smoothness of the device's operation.

[0024] The present invention is further configured such that a heating block is provided at one end of the support frame, and the heating block is located around the first groove.

[0025] Preferably, the heating blocks are arranged around the first groove, which can focus on heating the end of the food container to prevent the food from cooling down too quickly at the outlet. The layout design of the heating blocks can form a synergistic heating with the heating modules of the limiting block and the support frame, further improving the overall heat preservation effect.

[0026] In summary, the present invention has the following main beneficial effects:

The battery 2 provides unified power to the electric push rod 3 and the heating module, which simplifies the circuit structure of the device and improves energy utilization efficiency. The round hole 11 at one end of the support frame 8 facilitates the precise docking of the feeding tube 12 with the nasogastric tube, reducing the risk of food leakage.

[0048] For details regarding the above embodiments, please refer to [link / reference]. Figure 4 The inner wall of the positioning ring 7 has a through hole 9, and a support frame 8 is placed in the through hole 9. The through hole 9 on the inner wall of the positioning ring 7 provides a stable moving channel for the support frame 8, ensuring that it maintains linear movement during the pushing process. The through hole 9 can guide the support frame 8 to avoid it from deviating or getting stuck, thus improving the smoothness of the device's operation.

[0049] Second embodiment: Please refer to Figure 3 The difference between Embodiment 2 and Embodiment 1 is that, while retaining the features of Embodiment 1, a heating block 20 is added to one end of the first groove 14, so that the heating block 20 heats the end of the food container 12 near the stomach and esophagus. Although the support frame 8 and the limiting block 10 effectively heat the outer wall of the food container 12, the position of the heating block 20 facilitates the reheating of the food inside the food container 12, which improves the practicality of the product and the comfort of the user.

[0050] In practical operation, this invention:

[0051] The electric push rod 3 is powered by the built-in battery 2 of the handle 1. When the user triggers the button 13, the support frame 8 is manually pulled, causing the support frame 8, which is movably sleeved on the inner wall of the positioning ring 7, to move out. The feeding tube 12 is placed on the inner wall of the support frame 8, with one end of the feeding tube 12 located on the inner wall of the round hole 11. The feeding tube 12 is rotated so that it is threadedly connected to the inner ring of the positioning ring 7. Then, the first groove 14 on the inner wall of the support frame 8 is precisely engaged with the protrusion 16 at the end of the feeding tube 12, effectively limiting the position of the feeding tube 12. At the same time, the spring 5 on the fixing ring 4 cooperates with the connecting rod 6 to limit the movement of the support frame 8, ensuring that the feeding tube 12 is stable and reliable during the pushing process. This replaces the traditional manual push-pull piston operation method and reduces the burden on the user's arms.

[0052] Furthermore, the inner wall of the support frame 8 is movably connected to the limiting block 10. Through the cooperation of the slider 18 with the second groove 15 on the support frame 8, the position of the limiting block 10 can be adjusted so that the two sets of limiting blocks 10 interlock and wrap around the outer wall of the food container 12. The heating module built into the limiting block 10 works in conjunction with the support frame 8 to heat and keep the food container 12 warm from multiple angles. Especially in winter, it can effectively slow down the temperature drop of liquid food and prevent the food from being too cold, which may cause abdominal discomfort or physical discomfort to the consumer. This significantly improves the practicality of the product in low-temperature scenarios.

[0053] Furthermore, during operation, the start / stop and pushing speed of the electric push rod 3 are controlled by button 13. The output end of the electric push rod 3 drives the food in the feeding tube 12 to move forward, accurately delivering food or medicine into the patient's body. At the same time, the battery 2 continuously supplies power to the electric push rod 3 and the heating module. The entire process does not require manual pushing or pulling, which not only improves the efficiency of operation but also ensures the stability of food temperature and optimizes the clinical nursing experience.

[0054] Although embodiments of the present invention have been shown and described, these specific embodiments are merely explanations of the invention and are not intended to limit it. The specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples. After reading this specification, those skilled in the art may make modifications, substitutions, and variations to the embodiments as needed without departing from the principles and spirit of the invention, but such modifications, substitutions, and variations are protected by patent law as long as they are within the scope of the claims of the present invention.
