Description

Technical Field

[0001] This utility model relates to the field of medical device technology, specifically to a tube feeding device for critically ill patients with an improved structure. Background Technology

[0002] Critically ill patients are often unable to eat independently due to various diseases and require tube feeding devices to provide essential nutritional support. While traditional tube feeding devices can achieve basic feeding functions, they still have many shortcomings in practical application. For example, existing feeding devices are not precise enough in controlling the amount and speed of food feeding, which can easily lead to risks such as choking and aspiration in patients; moreover, their simple structural design lacks effective anti-contamination and ease-of-operation functions, causing inconvenience for medical staff and potentially affecting the patient's treatment outcome and recovery process.

[0003] Chinese patent document CN215536720U discloses a tube feeding device for critically ill patients with an improved structure. It includes a food storage cylinder with graduated lines on its outer surface, a filter plate fixedly connected to one end of the inner wall of the cylinder, and a connecting tube fixedly connected to one end of the outer surface of the cylinder. This nasogastric feeding device with an anti-backflow structure, through the arrangement of graduated lines, a filter plate, a tube cap, and a backflow valve, allows for the quantitative extraction of food or medication into the food storage cylinder via the graduated lines. The filter plate filters out large particles in the food or medication, preventing inconvenience for the patient during feeding and preventing blockage of the tube opening. The tube cap blocks the connecting tube when the feeder is not in use, preventing external dust and bacteria from entering and ensuring the patient's health. The backflow valve prevents the backflow of medication and food from the tube, improving feeding efficiency and reducing the risk of accidents.

[0004] Although the device described in the aforementioned literature can prevent backflow, its structure is relatively simple, it is not effective enough for filtering food, and its disassembly and assembly are not convenient enough, making it inconvenient for staff to clean and increasing their cleaning burden. In addition, it is easy for bacteria to grow, which is detrimental to patients, thus its practicality is insufficient. Utility Model Content

The device is equipped with a feeding mechanism that enhances filtration efficiency. The rotating and disassembly design allows medical staff to quickly and easily install and disassemble the feeding component for routine maintenance and replacement, reducing operational difficulty and improving work efficiency. The two-stage filter plate configuration facilitates double filtration of the feeding solution before it enters the patient's body, effectively removing particulate matter and impurities, reducing the risk of contamination, and protecting the patient's health and safety.

[0020] 2. This utility model provides a tube feeding device for critically ill patients with an improved structure. The device is equipped with a temperature control device to keep the food warm. The nutrient solution usually needs to be kept at a temperature close to the human body temperature to ensure that the patient can accept and absorb nutrients well. The appropriate temperature can reduce the stimulation of the patient's gastrointestinal tract and avoid discomfort or complications caused by excessively low or high temperatures. Some nutrients in the nutrient solution are sensitive to temperature, and maintaining an appropriate temperature helps to prevent the degradation and loss of these nutrients. For patients who are tube fed for a long time, the nutrient solution at an appropriate temperature can improve the comfort of feeding and reduce anxiety or discomfort caused by temperature discomfort. The power supply can make the heating wire heat up, and the heat is transferred to the tube feeding solution inside the storage cylinder by the heat conduction plate. The temperature sensor monitors in real time to prevent the food from getting cold or overheating and affecting the patient's feeding. The inner wall of the outer shell is equipped with a heat insulation plate to prevent heat from being transferred to the outside and avoid burns.

[0021] 3. This utility model provides a tube feeding device for critically ill patients with an improved structure. The device is equipped with a connecting device, which makes the device easier to assemble and disassemble. The quick assembly and disassembly design significantly reduces the preparation and cleaning time for medical staff before and after each feeding, improves overall work efficiency, facilitates quick switching between different patients, eliminates the need for complicated operating steps, and allows for timely cleaning and disinfection of the mouthpiece, helping to reduce the risk of cross-infection, ensure patient safety, reduce the psychological burden caused by the cumbersome feeding process, and make it easier for patients to accept tube feeding. A second slot is opened on one side of the fixing plate, allowing the mouthpiece to be inserted into the fixing plate with the second slot, and then locked in place by a spring plate, thus quickly fixing the mouthpiece. Conversely, the mouthpiece can be removed by simply pressing the spring plate. The spring plate and the locking plate have corresponding slots on one side, and the insertion of the pin can quickly lock the device, making the connection more stable. A third filter plate is set on one side of the mouthpiece, which can further improve the filtration effect, improve practicality, and reduce cleaning difficulty. Attached Figure Description

The rotating and disassembly design allows medical staff to quickly and easily install and disassemble the feeding component for routine maintenance and replacement, reducing operational difficulty and improving work efficiency. The two-stage filter plate configuration helps to filter the tube feeding solution twice before it enters the patient's body, effectively removing particulate matter and impurities, reducing the risk of contamination, and protecting the patient's health and safety. The precise feeding component and filtration system ensure accurate delivery of the tube feeding solution, avoiding inaccurate feeding due to impurities or blockages, and ensuring that the patient receives the predetermined amount of nutrition. The easily disassembled feeding component and filtration system simplify the cleaning and disinfection process, helping to improve overall hygiene management and reduce the possibility of cross-infection. A temperature control device 3 is fixedly connected to one side of the storage cylinder 1, which can be used to keep the food warm. Nutritional solutions typically need to be maintained at a temperature close to human body temperature to ensure that patients can well receive and absorb nutrients. A suitable temperature can reduce the risk to patients. To prevent gastrointestinal irritation and discomfort or complications caused by excessively low or high temperatures, the nutrient solution contains some temperature-sensitive nutrients. Maintaining a suitable temperature helps prevent the degradation and loss of these nutrients. For patients undergoing tube feeding for extended periods, a nutrient solution at a suitable temperature can improve feeding comfort and reduce anxiety or discomfort caused by temperature discomfort. A piston 4 is slidably connected to the inner wall of the feed cylinder 1. A push rod 5 is fixedly connected to one side of the piston 4, and a second handle 6 is fixedly connected to one side of the push rod 5.

The filter pores of the first filter plate are finer than those of the second filter plate, which can fully filter the incoming flow. Both the first and second feeding cylinders have threaded grooves on one side, which can be quickly opened and closed by simply rotating clockwise or counterclockwise. In addition, the upper end of the first feeding cylinder has a first slot that corresponds one-to-one with the first slot on the side of the first filter plate, making it easier to remove and clean.

[0035] like Figure 3 As shown, a heating wire 32 is fixedly connected to one side of the heat-conducting plate 31, a power supply 33 is fixedly connected to one end of the heating wire 32, a housing 34 is fixedly connected to one side of the power supply 33, and a heat insulation plate 35 is fixedly connected to the inner wall of the housing 34.

The second slot 75 is provided on one side of the fixed plate 71. 2. This allows the nozzle 73 to be inserted into the fixing plate 71 via the second locking plate 76, and then secured to the fixing plate 71 by the spring locking plate 77, thus quickly fixing the nozzle 73. Conversely, the nozzle 73 can be removed simply by pressing the spring locking plate 77. The spring locking plate 77 and the locking plate 78 have corresponding slots on one side, and the pin 79 can be inserted to quickly lock the connection, making the equipment connection more stable. A third filter plate 74 is provided on one side of the nozzle 73, which can further improve the filtration effect, improve practicality, and reduce the difficulty of cleaning.

[0037] The working principle of this utility model is as follows: The feeding device 2 allows for easy opening and closing of the feeding component by rotating the cover plate with the first handle. The feed liquid is poured into the second feeding cylinder and initially filtered by the second filter plate.

Additionally, the upper end of the first feeding cylinder has a first retaining groove that corresponds to the first retaining plate on one side of the first filter plate, making it easier to remove and clean. The temperature control device 3, powered by the power supply 33, energizes the heating wire 32, which in turn heats up. The heat is transferred to the inside of the storage cylinder 1 via the heat-conducting plate 31. The tube feeding solution is monitored in real time by a temperature sensor to prevent the food from getting too cold or too hot and affecting the patient's eating. A heat insulation plate 35 is set on the inner wall of the outer shell 34 to prevent heat from being transferred to the outside and avoid burns.
