Description

Technical Field

[0001] This utility model relates to an integrated device for configuring and pumping nutrient solution, specifically an integrated device for configuring and pumping nutrient solution in tube feeding, belonging to the field of tube feeding technology. Background Technology

[0002] Tube feeding is a method of delivering nutritional solutions to a patient's stomach or intestines through a tube. It is typically used for patients who cannot take oral medication or absorb sufficient nutrients, such as critically ill patients, post-operative patients, and patients with gastrointestinal diseases. Tube feeding can be administered through nasogastric tubes, nasoenteric tubes, or gastrostomies. Nasogastric tubes are inserted into the patient's nasal cavity, pass through the throat and esophagus, and finally reach the stomach. Nasoenteric tubes are inserted into the patient's nasal cavity, pass through the throat and esophagus, and finally reach the small intestine. Gastrostomies involve surgery in the patient's abdomen to insert a tube directly into the stomach or small intestine. It is an important means of nutritional support that helps patients maintain normal physiological functions and immunity, and promotes recovery.

[0003] The composition and formula of tube feeding solutions vary depending on the patient's specific condition, but generally include protein, carbohydrates, fats, vitamins, minerals, and water. The proportions and concentrations of these components need to be adjusted according to the patient's nutritional needs and digestive capacity.

[0004] Traditional tube feeding solutions are typically prepared using a syringe with a preparation container or a nutrient solution preparation machine. The prepared solution is then poured into a pumping device for manual administration. However, this process is complex and cannot quickly complete the preparation and administration of the nutrient solution. Furthermore, traditional pumping devices often retain some nutrient solution after use, requiring manual cleaning. This increases the workload for medical staff and poses a risk of infection if not properly cleaned. Therefore, this paper proposes an integrated device for preparing and administering tube feeding solutions. Utility Model Content

[0033] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0034] like Figure 1-6 As shown, this utility model embodiment provides an integrated device for preparing and pumping tube feeding nutrient solution, including a body component 1 and a pumping mechanism 2. The body component 1 includes a nutrient bag 101, a delivery pipe 102 and a tube feeding connector 103.

[0035] The delivery pipe 102 is located on one side of the nutrient bag 101, and the tube feeding connector 103 is connected to one end of the delivery pipe 102. A liquid dispensing bladder 4 is provided on one side of the inner wall of the nutrient bag 101, and a pressure-bearing air bladder 5 is provided on the other side of the inner wall of the nutrient bag 101. The liquid dispensing bladder 4 and the pressure-bearing air bladder 5 are adapted to each other. Two liquid dispensing mechanisms 3 are symmetrically connected to the outer wall of the liquid dispensing bladder 4, and a pumping mechanism 2 is located on one side of the pressure-bearing air bladder 5.

[0036] Among them, the pumping mechanism 2 is used to inject air into the interior of the pressure-bearing airbag 5, so that the pressure-bearing airbag 5 expands and squeezes the liquid distribution bag 4.

[0037] Among them, the liquid preparation bag 4 is used to provide space for preparing and storing tube feeding nutrient solution;

[0038] The liquid preparation mechanism 3 is used to control the opening or closing of the liquid preparation bag 4, and is used to connect to the nutrient solution preparation machine or bagged nutrient solution components by means of threads.

[0039] In one embodiment, the pumping mechanism 2 includes a housing 201, a miniature air pump 202, and an air pump connector 203;

[0040] One end of the air pump connector 203 is connected to one side of the pressure-bearing airbag 5, and the other end of the air pump connector 203 extends to the outside of the nutrient bag 101. The miniature air pump 202 is installed inside the housing 201, and the inner wall of the air pump connector 203 is threadedly connected to the exhaust port of the housing 201.

[0041] The housing 201 and the miniature air pump 202 are connected to the air pump connector 203 by threads, so that outside air can be injected into the interior of the pressure-bearing airbag 5 by the miniature air pump 202 through the air pump connector 203.

[0042] In one embodiment, both liquid dispensing mechanisms 3 include a liquid dispensing connector 301, a threaded groove 302, a sealing plug 303, and a buckle plate 304;

[0043] The liquid dispensing connector 301 is connected to the outer wall of the liquid dispensing bladder 4, and the other end of the liquid dispensing connector 301 extends to the outer side of the nutrient bag 101. The threaded groove 302 is opened on one side of the inner wall of the liquid dispensing connector 301. One end of the buckle plate 304 is fixedly connected to the outer wall of the liquid dispensing connector 301, and a sealing plug 303 is fixedly connected to one side of the buckle plate 304. The outer wall of the sealing plug 303 is slidably connected to the inner wall of the threaded groove 302.

[0044] The sealing plug 303 is slid out of the threaded groove 302 by moving the snap plate 304, so that the liquid dispensing bag 4 can be opened.

[0045] In one embodiment, the liquid preparation bag 4 is connected to a one-way valve 61 at one end near the delivery pipe 102, and the other end of the one-way valve 61 is connected to the end of the delivery pipe 102 away from the tube feed connector 103.

[0046] The one-way valve 61 prevents backflow of the tube feeding nutrient solution in the delivery pipe 102.

[0047] In one embodiment, an adjuster 62 is slidably connected to the outer wall of the delivery pipe 102.

[0048] The flow rate of the tube feeding nutrient solution in the delivery pipe 102 is controlled by pushing the regulator 62.

[0049] In one embodiment, a bag ear 63 is fixedly connected to one side of the outer wall of the nutrient bag 101; the bag ear 63 is used to hang the nutrient bag 101.

[0050] In one embodiment, such as Figure 6 As shown, the bagged nutrient solution includes a protein powder bag, a carbohydrate bag, a fat bag, a vitamin bag, a mineral bag, and a water bag. The outer wall of one end of the bagged nutrient solution is threaded to the inner wall of the threaded groove 302.

[0051] When this utility model is in operation: the nutrient bag 101 is taken out of the sealed bag as a whole, and then the buckle plate 304 is moved to drive the sealing plug 303 to slide out from the threaded groove 302 so as to open the liquid preparation bag 4. Then, the liquid preparation connector 301 is connected to the liquid outlet of the preparation machine or the liquid outlet of the bagged nutrient solution through the threaded groove 302 so as to directly inject the tube feeding nutrient solution prepared by the preparation machine or the unprepared nutrient solution into the interior of the liquid preparation bag 4.

[0052] When using unprepared nutrient solution components, select appropriate amounts of protein, carbohydrates, fats, vitamins, minerals, or water according to the patient's actual needs, and inject them sequentially into the solution preparation sac 4 by squeezing, so that the preparation operation can be completed directly in the solution preparation sac 4.

[0053] After the tube feeding nutrient solution or unprepared nutrient solution components are injected, the sealing plug 303 is slid into the threaded groove 302 by moving the buckle plate 304 to seal one end of the nutrient solution connector 301. Then, the nutrient solution components are fully mixed inside the nutrient solution bladder 4 by water bath heating and shaking.

[0054] After the tube feeding solution is prepared, heated, and mixed, the housing 201 and the miniature air pump 202 are connected to the air pump connector 203 using threads. Then, the delivery tube 102 is opened by pushing the regulator 62 so that the air in the delivery tube 102 can be expelled by the tube feeding solution flowing in the delivery tube 102. Then, the tube feeding connector 103 is connected to the patient's feeding tube. Then, the nutrition bag 101 is hung at a high place using the bag ear 63. Then, the speed of the tube feeding solution flowing in the delivery tube 102 is controlled by pushing the regulator 62.

[0055] Once the regulator 62 is adjusted, outside air is injected into the pressure-bearing airbag 5 using the micro air pump 202. The pressure-bearing airbag 5 expands under air pressure, squeezing the feeding nutrient solution in the dispensing bag 4, allowing the feeding nutrient solution in the dispensing bag 4 to be smoothly pumped into the patient's body. The feeding nutrient solution does not come into direct contact with the pumping mechanism 2, so there is no need to clean the pumping mechanism 2 after use, reducing the risk of infection. In addition, the nutrition bag 101, the dispensing bag 4, and the pressure-bearing airbag 5 are all disposable items, reducing the workload of medical staff.

[0056] The one-way valve 61 prevents backflow of the tube feeding nutrient solution in the delivery pipe 102.

[0057] The above are merely specific embodiments of this utility model, but the protection scope of this utility model is not limited thereto. Any person skilled in the art can easily conceive of various variations or substitutions within the technical scope disclosed in this utility model, and these should all be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
