[0002] After undergoing some special surgeries, patients are prohibited from eating directly through the mouth. In addition to total intravenous high-nutrient nutrition therapy, nasogastric feeding is also required to pump water and food into the patient's stomach to help patients who cannot swallow independently provide water and food to maintain metabolism, weight and nutrition in the body.

[0003] Nasogastric feeding is a method of artificially inserting a gastric tube into the esophagus through the nasal cavity, grinding the food into a paste with a grinder, and connecting a large syringe to the large injection port under the gastric tube connector. After the connection is secure, manually pressurize the push rod piston to push the liquid food into the gastric tube.

[0004] In the method of using a syringe to push liquid food, the temperature of the liquid food cannot be controlled, especially in cold weather. The liquid food is prone to cool down during the feeding process, and the cooled liquid food is prone to cause gastrointestinal dysfunction. In addition, the feeding process is completely dependent on manual labor, which is cumbersome to operate. Utility Model Content

DETAILED DESCRIPTION

[0029] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific preferred embodiments.

[0030] In the description of the present invention, it should be understood that the terms "left side", "right side", "upper part", "lower part", etc. indicate the orientation or position relationship based on the orientation or position relationship shown in the drawings, which is only for the convenience of describing the present invention and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. "First", "second", etc. do not indicate the importance of the components, and therefore cannot be understood as a limitation on the present invention. The specific dimensions used in this embodiment are only for illustrating the technical solution, and do not limit the scope of protection of the present invention.

[0031] like Figure 1 , Figure 2 and Figure 3 The embodiment of the present application discloses a gastroenterology fluid feeding device, including a water bath 1, a measuring cup 11 and a peristaltic pump 12. The water bath 1 is used to store water of different temperatures. A bracket 4 is provided in the water bath 1. The measuring cup 11 is used to hold liquid food. The measuring cup 11 is located in the water bath 1 and supported on the bracket 4. The side of the bracket 4 in contact with the measuring cup 11 is provided with a plurality of through grooves 41 to increase the contact area between the bottom of the measuring cup 11 and the water. The water bath 1 and the measuring cup 11 are both made of transparent materials to facilitate observation of the internal conditions. The transparent material can preferably be an acrylic plate.

[0032] like Figure 2 and Figure 4The input end and the output end of the peristaltic pump 12 are respectively connected to the first branch pipe 121 and the second branch pipe 122. The first branch pipe 121 and the second branch pipe 122 are both flexible and soft tubes. The first branch pipe 121 is used to draw liquid food from the measuring cup 11, and the end of the first branch pipe 121 is connected to the filter cartridge 13, and the filter cartridge 13 is provided with a filter screen 131.

[0033] like Figure 2 and Figure 5 The second branch tube 122 is connected with a connector 14 for connecting with a gastric tube. The connector 14 can be inserted into the gastric tube and form a tight fit with the gastric tube to ensure the sealing of the connection between the two.

[0034] like Figure 4 The end of the filter cartridge 13 close to the first branch pipe 121 is connected with a cone pipe 132 which is connected with the filter cartridge 13. The large diameter end of the cone pipe 132 is coaxially connected with the filter cartridge 13. The small diameter end of the cone pipe 132 is inserted into the first branch pipe 121, and the two are tightly matched to achieve a sealed connection between the cone pipe 132 and the first branch pipe 121. A clamping ring 133 is provided on the filter cartridge 13. The diameter of the clamping ring 133 is larger than the maximum diameter of the cone pipe 132. When the inner diameter of the first branch pipe 121 is large, the operator can wrap the first branch pipe 121 around the clamping ring 133 to enhance the connection.

[0035] When in use, the operator injects water of the required temperature into the water bath 1, places the measuring cup 11 containing the liquid food on the bracket 4, inserts the filter cartridge 13 into the liquid food after the water bath is heated for a period of time, and starts the peristaltic pump 12. After the liquid food is filtered by the filter screen 131, it is transported to the stomach tube through the filter cartridge 13, the cone tube 132, the first branch tube 121 and the second branch tube 122. Since the cone tube 132 and the first branch tube 121 are plugged together, the operator can replace the filter cartridge 13 as a whole and adjust the specifications of the filter cartridge 13. The filter screen 131 in the filter cartridges 13 of different specifications has different apertures to meet the use requirements of different liquid foods, reducing the possibility of large particles in the liquid food blocking the pipeline, and also protecting the patient. The water bath heating has the effect of heat preservation, slowing down the cooling speed of the liquid food, and avoiding irritation of the patient's stomach and intestines.

[0036] In some embodiments, in order to increase the convenience of water bath heating, an electric heater may be installed in the water bath 1, and the water in the water bath 1 may be heated to a desired temperature using the electric heater.

[0037] like Figure 1 A support plate 2 is provided on the side wall of the water bath 1 , and an elastic protective sleeve 21 is provided on the support plate 2 for the first branch pipe 121 to pass through. The elastic protective sleeve 21 wraps and fixes the first branch pipe 121 to protect the first branch pipe 121 from being worn by the side wall of the water bath 1 .

[0038] like Figure 2 and Figure 6The inner wall of the water bath 1 is provided with a backing plate 3, and a sealing plate 31 is supported on the backing plate 3. The sealing plate 31 includes a first surface and a second surface opposite to each other, the first surface extends along the outer contour of the water bath 1, and the second surface extends along the outer contour of the measuring cup 11. The first surface and the second surface of the sealing plate 31 are both connected with a sealing ring 32, the sealing ring 32 corresponding to the first surface abuts against the inner wall of the water bath 1, and the sealing ring 32 corresponding to the second surface is sleeved outside the measuring cup 11. The sealing plate 31 and the sealing ring 32 are used to achieve sealing and shielding between the water bath 1 and the measuring cup 11, which is conducive to reducing the possibility of water overflowing from the water bath 1 during movement or collision, and has a safety protection function.

[0039] The sealing plate 31 is provided with a water inlet 33 which is in communication with the interior of the water bath 1 , so as to facilitate water injection into the water bath 1 . An end cap 34 for closing the water inlet 33 is threadedly connected to the water inlet 33 .

[0040] The bracket 4 is provided with a plurality of positioning blocks 42 distributed around the measuring cup 11; when the measuring cup 11 abuts against each positioning block 42, the two sealing rings 32 can respectively cooperate with the water bath 1 and the measuring cup 11, that is, the sealing ring 32 corresponding to the first surface abuts against the inner wall of the water bath 1, and the inner peripheral surface of the sealing ring 32 corresponding to the second surface abuts against the outer peripheral surface of the measuring cup 11. The positioning block 42 plays a role in positioning the position of the measuring cup 11, so that the operator can quickly determine the position of the measuring cup 11 when covering the sealing plate 31, so that the measuring cup 11 can be smoothly exposed from the hole in the middle of the sealing plate 31.

[0041] The above description is only a specific implementation of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed by the present invention, which should be included in the protection scope of the present invention.
