Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to a nasogastric feeding device. Background Technology

[0002] Nasogastric feeding is a special procedure in which a feeding tube is inserted into the esophagus through the nasal cavity. The food is first ground into a paste using a grinder, and a large syringe is used to connect to the large feeding port below the feeding tube connector. After the connection is secure, the piston is manually pressurized to inject water and food into the patient's stomach, helping patients who cannot swallow independently to receive water and food, and maintain their metabolism, weight, and nutrition.

[0003] Clinically, patients requiring nasogastric feeding are mostly fed via syringe. While this method is simple, the syringe's maximum capacity is only 50 ml. Repeated aspiration of the feeding solution during the feeding process easily contaminates the syringe. Secondly, only 50 ml of gastric contents can be aspirated at a time, making it impossible for medical staff to know the remaining gastric volume. Thirdly, repeated aspiration increases the workload of nurses and prolongs the feeding time, causing discomfort to the patient. Fourthly, during repeated aspiration, nurses may not properly fold the feeding tube, allowing air to fill the tube and repeatedly injecting air into the stomach, increasing the risk of abdominal distension. Fifthly, if interrupted during repeated feeding, nurses may forget the amount of feeding solution already administered, leading to incorrect dosage. Sixthly, because the syringe's connection to the feeding tube lacks reinforcement, and some feeding solutions contain edible oil, the syringe can easily detach from the feeding tube during feeding, causing spillage, waste, and increased patient discomfort. Seventh, some nasogastric feeding solutions have a sedimentation effect and tend to settle in the syringe during feeding, resulting in uneven injection and increasing the risk of gastric tube blockage. Currently, there are no nasogastric feeding devices available clinically that offer a single large dose, prevent separation of the feeding device from the gastric tube, and have a stirring function.

[0004] Therefore, it is necessary to provide a nasogastric feeding device with a large capacity that can hold the required amount of nasogastric feeding solution in one go, thereby reducing the number of times the nasogastric feeding solution is repeatedly aspirated, reducing the chance of infection, and being easy to operate. Utility Model Content

[0005] The purpose of this invention is to provide a nasogastric feeding device with a large capacity that can hold the required amount of nasogastric feeding solution for a patient in one go, thereby reducing the number of times the nasogastric feeding solution is repeatedly aspirated, reducing the chance of infection, and being easy to operate.

[0006] To achieve the above objectives, this utility model provides a nasogastric feeding device, comprising:

[0007] A volumetric flask is provided with a hollow receiving cavity. One end of the receiving cavity is open to form an opening, and the other end of the receiving cavity is provided with a bottom cover with a liquid outlet.

[0008] The cover assembly includes a top cover, on which a stirring element is provided. The stirring element has a flexible structure. The top cover covers the opening and is sealed between the top cover and the opening, so that the stirring element is located in the receiving cavity. A handle is provided on the side of the top cover away from the stirring element for easy gripping. By operating the handle, the top cover can be moved in the receiving cavity, so that the liquid in the receiving cavity can be discharged from the outlet.

[0009] The liquid dispensing assembly, connected to the liquid outlet, includes a liquid dispensing component connected to the gastric tube. One end of the liquid dispensing component is provided with a switch for opening and closing the liquid dispensing component, and the other end of the liquid dispensing component is provided with an injection tube for injecting medication. The injection tube is detachably provided with a sealing cap.

[0010] Compared with existing technologies, the nasogastric feeding device of this invention has a larger volumetric flask capacity, allowing for the full dose of nasogastric feeding to be filled in one go, reducing the number of times the feeding solution is repeatedly aspirated and lowering the risk of infection. Based on human nasogastric feeding requirements, the maximum capacity of this feeding device can reach 300 ml, eliminating the need for caregivers to repeatedly separate the gastric tube from the feeding device, significantly reducing the chance of air entering the gastric tube and minimizing abdominal distension. The cap assembly of the feeding device can be detached from the volumetric flask, allowing the feeding solution to be poured directly into the feeding device, eliminating the need for aspiration, saving time and reducing the workload of caregivers, thus saving labor costs. Furthermore, the movement of the top cap within the volumetric flask allows the liquid in the flask to be discharged from the outlet. The feeding device also includes a handle for easier operation. The feeding device includes a stirring component, which can agitate the feeding solution throughout the feeding process, ensuring even distribution of the solution into the gastric tube and significantly reducing the risk of gastric tube blockage. In addition, this nasogastric feeding device has a large capacity, allowing for the aspiration of large volumes of gastric contents, ensuring that medical staff can accurately determine whether gastric retention has occurred, and greatly facilitating the observation of the patient's condition. The feeding device is also of a suitable size, making it easy for nursing staff to hold and operate. This new type of nasogastric feeding device has a large capacity, capable of holding the full dose required for nasal feeding in one go, reducing the need for repeated aspiration of feeding fluid, lowering the risk of infection, and offering convenient operation.

[0030] To explain the technical content and structural features of this utility model in detail, the following description is provided in conjunction with the embodiments and accompanying drawings.

[0031] Please see Figure 1 and Figure 2 This utility model provides a nasogastric feeding device 100, including a volumetric flask 10. One end of the volumetric flask 10 is provided with a cap assembly 20, and the other end is connected to a dispensing assembly 30. Specifically, the volumetric flask 10 has a hollow receiving cavity 101. One end of the receiving cavity 101 is open to form an opening 14, and the other end of the receiving cavity 101 is provided with a bottom cap 15, on which a dispensing port 13 is formed. The cap assembly 20 includes a top cap 21, on which a stirring element 23 is provided. The stirring element 23 has a flexible structure. The top cap 21 covers the opening 14 and is sealed to the opening 14, allowing the stirring element 23 to be located within the receiving cavity 101. The stirring element 23, located within the receiving cavity 101, can stir within the receiving cavity 101 to ensure the nasogastric feeding solution is evenly mixed, thereby reducing the risk of gastric tube blockage. A handle 22 for easy gripping is provided on the side of the top cover 21 away from the stirring member 23. By operating the handle 22, the top cover 21 can be moved within the receiving cavity 101, allowing the liquid in the receiving cavity 101 to be discharged from the outlet 13. On the other hand, the dispensing assembly 30 is connected to the outlet 13. The dispensing assembly 30 includes a dispensing element 31 connected to the gastric tube. The nasogastric feeding solution in the receiving cavity 101 flows through the dispensing element 31 and into the human body via the gastric tube. One end of the dispensing element 31 is provided with a switch 32 for opening and closing the dispensing element 31. When the switch 32 is open, the nasogastric feeding solution can enter the dispensing element 31 and then into the human body. When the switch 32 is closed, the dispensing element 31 is blocked from the outlet 13, stopping the liquid supply. The other end of the dispensing element 31 is provided with an injection tube 33 for injecting medication. A sealing cap 34 is detachably provided on the injection tube 33. For pre-meal, during-meal, and post-meal medication administration, the sealing cap 34 can be opened without separating the nasogastric device 100 from the gastric tube. The medication can then be injected through the injection tube 33 using a syringe, thus reducing the risk of infection and greatly facilitating patient treatment. After the medication is injected, the injection tube 33 is sealed with the sealing cap 34, ensuring convenience and hygiene.

[0032] Compared with existing technologies, the nasogastric feeding device 100 of this invention has a larger capacity volumetric flask 10, which can hold the full dose required for nasogastric feeding in one go, reducing the number of times the feeding solution is repeatedly aspirated and lowering the risk of infection. Based on the human body's nasogastric feeding requirements, the maximum capacity of this feeding device 100 can be 300ml, eliminating the need for caregivers to repeatedly separate the gastric tube from the feeding device 100, greatly reducing the chance of air entering the gastric tube and reducing the occurrence of abdominal distension in patients. The cap assembly 20 of the feeding device 100 can be detached from the volumetric flask 10, allowing the feeding solution to be poured directly into the feeding device 100, eliminating the need for aspiration, saving time, reducing the workload of caregivers, and saving labor costs. Furthermore, the liquid in the volumetric flask 10 can be discharged from the outlet 13 by the movement of the top cap 21 within the volumetric flask 10. Additionally, the feeding device includes a handle 22 for easier operation. The nasogastric feeding device 100 includes a stirring element 23, which can stir the feeding solution throughout the feeding process, ensuring that the solution is evenly injected into the gastric tube and greatly reducing the risk of gastric tube blockage. In addition, the nasogastric feeding device 100 has a large capacity, allowing for large-volume aspiration of gastric contents, ensuring that medical staff can accurately determine whether gastric retention has occurred, greatly facilitating the observation of the patient's condition. The nasogastric feeding device 100 is of a suitable size, making it easy for nursing staff to hold and operate. This utility model's nasogastric feeding device 100 has a large capacity, capable of holding the full dose required for nasal feeding in one go, reducing the need for repeated aspiration of the feeding solution, lowering the risk of infection, and is easy to operate.

[0033] Please see Figure 1 and Figure 2 In some optional embodiments, the volumetric flask 10 is provided with graduations 12. The nasogastric feeding device 100 has a maximum capacity of 300 ml, eliminating the need for caregivers to repeatedly separate the gastric tube from the feeding device 100, greatly reducing the chance of air entering the gastric tube and minimizing abdominal distension in patients. The volume graduations 12 on the feeding device 100 are clear, allowing for a single filling to meet the required feeding dose. Caregivers do not need to repeatedly add up the doses of aspirated feeding solution to calculate the total feeding volume, ensuring accurate feeding dosage.

[0034] Please see Figures 1 to 4 In some optional cases, a handle 22 is foldably mounted on the top cover 21. The top cover 21 has a first connecting portion 211 and a receiving groove 212. The handle 22 has a second connecting portion 221 connected to the first connecting portion 211. The handle 22 is movably connected to the first connecting portion 211 via the second connecting portion 221. The handle 22 can move at multiple angles on the top cover 21 and can be folded into the receiving groove 212 on the top cover 21 for easy storage. When it is necessary to operate the top cover 21 within the receiving cavity 101 to allow the nasal feeding solution within the receiving cavity 101 to enter the body, the handle 22 can be rotated to more conveniently move the top cover 21 within the receiving cavity 101. Figure 2As shown, a telescopic part 222 is also provided on the handle 22. As the top cover 21 gradually moves into the accommodating cavity 101, the length of the handle 22 can be increased by the telescopic part 222 on the handle 22, so as to facilitate the operation of the top cover 21 outside the accommodating cavity 101.

[0035] Please see Figures 1 to 3 In some optional embodiments, a first threaded portion 11 is provided inside the accommodating cavity 101, and a second threaded portion 213 is provided on the outer periphery of the top cover 21. The top cover 21 is screwed to the volumetric flask 10 via the second threaded portion 213. By rotating the handle 22, the top cover 21 rotates along the first threaded portion 11, gradually pushing the liquid in the volumetric flask 10 out through the outlet 13. Specifically, the second threaded portion 213 rotates along the first threaded portion 11, causing the stirring member 23 to rotate with the top cover 21, so that the stirring member 23 can stir the liquid in the accommodating cavity 101. The stirring member 23 has a flexible structure. When the stirring member 23 moves downward with the top cover 21, the stirring member 23 moves flexibly without affecting the movement of the top cover 21 or the stirring of the stirring member 23.

[0036] Please see Figure 1 and Figure 2 In some alternative embodiments, a sealing element is provided on the surface of the top cover 21 that mates with the receiving cavity 101, thereby sealing the top cover 21 with the receiving cavity 101. The top cover 21 is slidably disposed within the receiving cavity 101. By pushing the handle 22, the top cover 21 slides along the receiving cavity 101, allowing the liquid in the volumetric flask 10 to flow out through the outlet 13. During the pushing of the top cover 21, the handle 22 can be used to cause the top cover 21 to rotate and slide within the receiving cavity 101, so that while the top cover 21 slides downwards, the stirring element 23 can stir the nasal feeding solution within the receiving cavity 101.

[0037] Please see Figure 1 and Figure 2 In some optional embodiments, the dispensing assembly 30 further includes a connector 35 connected to the dispensing port 13, the connector 35 being connected to the dispensing component 31, and a switch 32 disposed between the connector 35 and the dispensing component 31. The dispensing component 31 is always connected to the injection tube 33; opening the sealing cap 34 on the injection tube 33 allows the medication to be injected into the dispensing component 31. Conversely, the dispensing component 31 is only connected to the volumetric flask 10 when the switch 32 is turned on.

[0038] like Figures 1 to 4As shown, the nasogastric feeding device 100 of this invention has a large-capacity volumetric flask 10, which can hold the required feeding dose for the patient in one go, reducing the number of times the feeding solution is repeatedly aspirated and lowering the risk of infection. Based on the human body's nasogastric feeding requirements, the maximum capacity of the feeding device 100 can be 300 ml, eliminating the need for caregivers to repeatedly separate the gastric tube from the feeding device 100, greatly reducing the chance of air entering the gastric tube and reducing the occurrence of abdominal distension. Simultaneously, the feeding device 100 can aspirate large volumes of gastric contents, ensuring that medical staff can accurately determine whether gastric retention has occurred, greatly facilitating the observation of the patient's condition. The cap assembly 20 of the feeding device 100 can be detached from the volumetric flask 10, allowing the feeding solution to be poured directly into the feeding device 100, eliminating the need for aspiration, saving time, reducing the workload of caregivers, saving time and effort, and conserving labor costs. Furthermore, the liquid in the volumetric flask 10 can be discharged from the outlet 13 by moving the top cap 21 within the flask. The nasogastric tube also includes a handle 22 for easier operation. The nasogastric tube 100 includes a stirring element 23, which agitates the feeding solution throughout the feeding process, ensuring even distribution into the gastric tube and significantly reducing the risk of blockage. Additionally, the nasogastric tube 100 has a large capacity, allowing for large-volume aspiration of gastric contents, ensuring accurate assessment of gastric retention by healthcare professionals and greatly facilitating patient monitoring. Its appropriate size makes it easy for nursing staff to handle and operate. This invention's nasogastric tube 100 has a large capacity, capable of holding the required feeding dose in a single operation, reducing the need for repeated aspirations, lowering the risk of infection, and offering convenient operation.
