Abstract
Description
Technical Field
[0001] This utility model relates to the field of newborn feeding technology, and in particular to a simple partial nasogastric feeding device. Background Technology
[0002] Newborn feeding has always been a crucial aspect of medical care and family childcare. For newborns who cannot feed themselves through sucking, especially premature infants or those with certain illnesses, traditional feeding methods present numerous problems. Although breast milk is the best source of nutrition for newborns, most newborns (such as premature infants) are born with only a small amount of breast milk from their mothers, and these newborns often have weak sucking abilities and cannot obtain enough milk to meet their feeding needs.
[0003] Existing simple nasogastric feeding devices are generally syringe-type feeding devices. For example, the utility model patent CN202322451650.5, entitled "A Gravity Gastric Tube Feeding Device for Premature Infants," discloses a device that fills a syringe with formula milk, fixes the syringe to a retractable suction cup, and fixes the suction cup at a high position so that the formula milk in the syringe flows into the gastric tube by gravity and is then injected into the infant's stomach. However, this feeding device only uses a gastric tube for feeding and cannot meet the infant's innate need for self-feeding. Moreover, it cannot be used for breastfeeding when the mother has only a small amount of breast milk.
[0004] Therefore, existing technologies still need to be improved and enhanced. Utility Model Content
[0005] In view of the shortcomings of the prior art, the purpose of this utility model is to provide a simple partial nasogastric feeding device that can meet the infant's natural need for independent sucking while feeding through a gastric tube.
[0006] To solve the above technical problems, the present invention adopts the following technical solution:
[0007] A simple partial nasogastric feeding device includes a milk storage container, a milk infusion tube, a gastric tube, and a nipple. The two ends of the milk infusion tube are connected to the milk storage container and the nipple, respectively. The nipple is provided with a milk absorbent and a breast milk inlet. One end of the gastric tube is connected to the milk storage container, and the other end of the gastric tube is used for feeding the newborn.
[0008] In the aforementioned simplified partial nasogastric feeding device, speed regulators are installed on both the milk inlet tube and the gastric tube.
[0009] In the aforementioned simplified partial nasogastric feeding device, the top of the milk storage container has a liquid inlet, and a sealing cap is provided at the liquid inlet.
[0010] In the aforementioned simplified partial nasogastric feeding device, a hanging component is provided on the top of the sealing cover or milk storage container. When the hanging component is placed on the sealing cover, it is used to control the opening of the sealing cover.
[0011] In the aforementioned simplified partial nasogastric feeding device, the speed controller is a digital speed controller.
[0012] In the aforementioned simplified partial nasogastric feeding device, the speed regulator includes a housing, a speed regulating component, and a knob control component. The housing has a through hole for a milk delivery tube or gastric tube to pass through. The knob control component is located at one end of the speed regulating component, and the other end of the speed regulating component is suspended and can extend into the through hole to block a portion of the through hole. The speed regulating component is screwed to the housing. The housing has a digital label for indicating the speed regulation level at one end of the knob control component, and the knob control component has an indicator label.
[0013] In the aforementioned simplified partial nasogastric feeding device, the milk storage container is equipped with graduations; and a heating element is fitted onto the gastric tube.
[0014] In the aforementioned simplified nasogastric feeding device, the nipple is provided with a head-fixing rope, a tightening rope, or Velcro on both sides.
[0015] In the aforementioned simplified partial nasogastric feeding device, the head-fixing rope or tightening rope is an elastic rope.
[0016] In the aforementioned simplified partial nasogastric feeding device, the milk storage container is either a rigid milk storage container or a flexible milk storage container.
[0017] In the aforementioned simplified nasogastric feeding device, the nipple has attachment parts on both sides, and the side of the attachment part that is attached to the newborn's face is provided with hydrocolloid.
[0018] Compared to existing technologies, the simplified partial nasogastric feeding device provided by this invention allows newborns to ingest breast milk through a nipple, stimulating their taste buds and enabling them to absorb immune-active substances from the breast milk, thus achieving oral immunity. Simultaneously, a feeding tube delivers formula directly into the newborn's stomach, ensuring adequate nutrition for growth and development. For newborns without breast milk, the feeding tube can also deliver formula to the nipple to meet their feeding needs. This dual supply of breast milk and formula satisfies the newborn's oral immunity and nutritional requirements, while also developing their sucking ability. Attached Figure Description

[0026] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.
[0027] It should be noted that when a component is referred to as being "mounted on," "fixed to," or "set on" another component, it can be directly on the other component or may have an intervening component present. When a component is referred to as being "connected to" another component, it can be directly connected to the other component or may have an intervening component present.
[0028] It should also be noted that the directional terms such as left, right, up, and down in the embodiments of this utility model are only relative concepts or are based on the normal use state of the product, and should not be considered as restrictive.
[0029] Please see Figure 1The simplified nasogastric feeding device provided by this utility model includes a milk storage container 1, a milk delivery tube 2, a gastric tube 3, and a nipple 4. The two ends of the milk delivery tube 2 are connected to the milk storage container 1 and the nipple 4, respectively. The nipple 4 is equipped with a milk absorbent 41 and a breast milk inlet (not labeled in the figure). A sealing plug 43 is provided at the breast milk inlet to prevent breast milk leakage and to prevent external contamination from entering the nipple 4, thus ensuring the health of the newborn. One end of the gastric tube 3 is connected to the milk storage container 1, and the other end is used for feeding the newborn.
[0030] The milk absorbent 41 can be made of absorbent materials such as cotton balls or sponges. Before use, an appropriate amount of breast milk is injected into the nipple 4 through the breast milk inlet. The milk absorbent 41 in the nipple 4 absorbs the breast milk, preventing it from flowing directly out of the nipple 4. Then, the breast milk-filled nipple 4 is gently placed into the newborn's mouth, allowing the newborn to latch onto it. The temperature of the breast milk should be adjusted beforehand to be close to body temperature (approximately 37°C) to ensure the newborn's comfort while sucking. When the newborn sucks on the nipple 4, the breast milk in the milk absorbent 41 slowly enters their mouth, satisfying the newborn's sucking needs without causing choking due to excessively fast breast milk flow. It also provides taste stimulation to the newborn's mouth and allows them to absorb immune-active substances from the breast milk, achieving oral immunity. For newborns who do not have access to breast milk, formula can be injected directly into the nipple 4 through the milk infusion tube 2 to ensure that newborns with weak swallowing ability can take in some food by sucking, thus exercising their sucking ability. At the same time, feeding can be done through a gastric tube to ensure that newborns receive sufficient nutrition.
[0031] This novel feeding device not only provides essential nutritional support for newborns but also meets their oral immune needs to a certain extent. The nipple provides breast milk or formula, helping newborns develop their sucking ability and also serves as a pacifier, offering psychological comfort. The continuous supply of formula ensures the nutritional supply necessary for their physical development. This dual-function design considers both the physiological and oral immune needs of newborns, contributing to their healthy growth. Furthermore, this simplified partial nasogastric feeding device is simple in structure, low in cost, and can be manufactured as a disposable item, suitable for newborn feeding in ICUs and incubators.
[0032] Both the milk infusion tube 2 and the gastric tube 3 are equipped with speed regulators 5, which can flexibly adjust the milk infusion speed according to the actual needs of the newborn. This design can effectively prevent the newborn from choking due to excessive milk flow, ensuring the safety and comfort of the feeding process.
[0033] The speed controller 5 is a digital speed controller, which can more precisely control the milk flow rate according to the actual needs of the newborn. Through the digital speed controller 5, medical staff can flexibly adjust the milk flow rate according to the newborn's actual needs, ensuring a moderate milk flow rate and preventing choking caused by excessively fast milk flow, thus ensuring the safety of newborn feeding. When breast milk is flowing into the nipple, the speed controller 5 on the milk infusion tube 2 can be adjusted to the highest setting, preventing formula milk from flowing from the milk storage container 1 into the nipple 4.
[0034] In an alternative embodiment, please refer to Figure 2 The speed regulator 5 includes a housing 51, a speed regulating component 52, and a knob control component 53. The housing 51 has a through hole (not labeled in the figure) for the milk delivery tube 2 or the gastric tube 3 to pass through. The knob control component 53 is located at one end of the speed regulating component 52. The other end of the speed regulating component 52 is an arc surface and is suspended. The other end of the speed regulating component 52 can extend into the through hole and block part of the through hole. That is, the other end of the speed regulating component 52 can press against the milk delivery tube 2 or the gastric tube 3, causing the milk delivery tube 2 or the gastric tube 3 to deform and control the dripping speed of the milk. The speed regulating component 52 is threadedly connected to the housing 51. One end of the housing 51, located on the knob control component 53, is provided with a digital indicator for indicating the speed setting. The knob control component 53 is correspondingly provided with an indicator 54. During speed adjustment, the screw length between the speed regulating component 52 and the housing 51 is adjusted by rotating the knob control component 53, thereby adjusting the depth of the other end of the speed regulating component 52 extending into the through hole. This controls the cross-sectional size of the milk delivery tube 2 or gastric tube 3 within the speed regulator 5, thus regulating the milk flow rate. This allows for more precise control of the milk flow rate. Furthermore, the speed regulator 5 has a simple structure, low cost, and is suitable for disposable feeding products. The curved end face also facilitates deformation of the milk delivery tube or gastric tube during rotation.
[0035] Of course, the structure of the speed controller 5 is not limited to this. It can also use the infusion drip rate regulator on the existing infusion tubing, or other types of digital speed controllers, such as the speed controller disclosed in the patent with patent number 202323646116.6. It can be used to adjust the liquid flow rate simply by installing it on the milk infusion tube 2 or the gastric tube.
[0036] The top of the breast milk storage container 1 has an injection port (not labeled in the figure), and a sealing cap 11 is provided at the injection port. The sealing cap 11 can be made of silicone. Through the injection port, medical staff can conveniently and quickly inject the breast milk, while the sealing cap 11 ensures the hygiene and airtightness of the injection process, preventing external contamination from entering the breast milk storage container 1 and protecting the health of the newborn.
[0037] A hanging member 12 is provided on the top of the sealing cap 11 or the milk storage container 1 to facilitate hanging the milk storage container 1 and thus improve milk delivery. When the hanging member 12 is installed on the sealing cap 11, it can also be used to control the opening of the sealing cap 11, so that the hanging member 12 is not limited to hanging but can also be used to control the opening of the sealing cap 11. This design allows the hanging member 12 to be used both to open the sealing cap 11 and to hang the milk storage container 1, making it more convenient to use and simplifying the structure of the simpler nasogastric feeding device.
[0038] Furthermore, the top of the milk storage container 1 is also integrally provided with a connector, the end of which is connected to the sealing cover 11 to prevent the sealing cover 11 from being lost when adding milk, or to prevent the milk storage container 1 from falling down when the hanging member 12 is suspended and the milk delivery tube 2 or the gastric tube 3 is accidentally pulled and the sealing cover 11 is accidentally opened.
[0039] In addition, the breast milk storage container 1 is equipped with graduations (not shown in the figure) to allow medical staff to clearly observe the feeding amount and ensure the accuracy of each feeding. Of course, medical staff can also prepare the milk in advance in the measuring instrument and then pour it directly into the breast milk storage container 1.
[0040] Please refer to the following: Figure 3 and Figure 4 The gastric tube 3 is fitted with a heating element 6, which can heat the milk fed into the newborn's stomach to a suitable temperature (about 37°C), making it more in line with the newborn's digestive and absorption needs, and avoiding discomfort to the newborn due to the milk being too low or too high in temperature.
[0041] In an optional embodiment, the heating element 6 includes a heating element 61, a temperature sensor 62, two semi-circular sleeves 63, and a main board (not shown in the figure). The heating element 61 and the temperature sensor 62 are disposed on the inner wall of the same semi-circular sleeve 63 and are electrically connected to the main board. Alternatively, heating elements 61 can be disposed on the inner walls of both semi-circular sleeves 63 to heat the milk in the gastric tube 3 more quickly and evenly. The temperature sensor 62 is located below the heating element 61 and is used to monitor the temperature of the milk in the gastric tube 3 in real time and feed the temperature data back to the main board. The main board is disposed in the housing of the heating element 6 and automatically adjusts the heating power of the heating element 61 according to the feedback temperature information to ensure that the milk output through the gastric tube 3 is always kept at a set constant temperature (approximately 37°C).
[0042] The two semi-circular sleeves 63 are connected on one side by a hinge, and fixed on the other side by a snap-fit structure 64. During installation, the two semi-circular sleeves 63 are clamped onto the gastric tube 3, so that their inner walls are tightly fitted against the outer wall of the gastric tube 3, thereby uniformly heating the milk inside the gastric tube 3. This detachable design facilitates the installation and removal of the heating element 6, allowing it to be reused and effectively reducing operating costs.
[0043] On the outer side of one of the semicircular sleeves 63, there is a temperature display screen 65, a control button 66, and a power button 68. The temperature display screen 65 is electrically connected to the main board and can display the temperature of the milk in the gastric tube 3 in real time; the control button 66 is electrically connected to the main board, and the user can manually adjust the heating temperature of the heating element 61 through the control button 66 to achieve precise temperature control and meet different feeding needs.
[0044] In addition, to improve stability, anti-slip components 67 are provided at both ends of the inner walls of the two semi-circular sleeves 63. These anti-slip components 67 can effectively prevent the heating element 6 from sliding on the gastric tube 3, ensuring that the heating element 6 remains in a fixed position during use, and guaranteeing the stability and safety of the heating effect. The outer wall of the semi-circular sleeves 63 can also be provided with anti-slip textures to facilitate the user's installation of the heating element 6.
[0045] In this embodiment, the heating element 6 is a detachable external component that can be installed as needed; for example, it can be left unused when the ambient temperature is high. The main board includes a control circuit to control the operation of the heating element 61, the temperature display screen 65, and the control buttons 66. Please refer to... Figure 5 The control circuit includes a temperature control chip U1, a first MOSFET Q1, a second MOSFET Q2, a third MOSFET Q3, a first resistor R1, a second resistor R2, a third resistor R3, a fourth resistor R4, a fifth resistor R5, a sixth resistor R6, a seventh resistor R7, an eighth resistor R8, and a ninth resistor R9.
[0046] The temperature control chip U1 can be an HT66F018 or other similar temperature control chip U1. The PA0 pin of the temperature control chip U1 is grounded through the power button 68 and also connected to the power supply terminal through the ninth resistor R9. The PA3 pin of the temperature control chip U1 is connected to the control button 66 and also connected to the power supply terminal through the first resistor R1. When the power button 68 is pressed, the PA0 pin of the temperature control chip U1 is pulled low. At this time, the control button 66 can be pressed. The heating temperature of the heating element 62 is set according to the number of times the control button 66 is pressed, such as setting the heating temperature of the heating element 62 to 42℃, and the temperature is displayed accordingly on the temperature display screen 65.
[0047] The PA7 pin of the temperature control chip U1 is connected to the gate of the first MOSFET Q1 through the second resistor R2. The drain of the first MOSFET Q1 is connected to the 9th pin of the temperature display screen through the third resistor R3. The source of the first MOSFET Q1 is grounded. The PB4 pin of the temperature control chip U1 is connected to the gate of the second MOSFET Q2 through the fourth resistor R4. The drain of the second MOSFET Q2 is connected to the 10th pin of the temperature display screen 65 through the fifth resistor R5. The source of the second MOSFET Q2 is grounded. The PC1, PC2, PB6, PB5, PB2, PA4, PA5, and PA6 pins of the temperature control chip U1 are connected to the 1st to 8th pins of the temperature display screen 65, respectively. The PB1 pin of the temperature control chip U1 is connected to the temperature sensor 62 and is also grounded through the eighth resistor R8.
[0048] When the control button 66 is pressed, the PB4 and PA7 pins of the temperature control chip U1 output a high level, turning on the first MOSFET Q1 and the second MOSFET Q2, so that the temperature display screen 65 displays the corresponding set temperature. The temperature sensor 62 detects the temperature of the heating element 61 and feeds it back to the temperature control chip U1, which then controls the temperature display screen 65 to display the corresponding temperature.
[0049] The PB3 pin of the temperature control chip U1 is connected to the gate of the third MOSFET Q3 through the sixth resistor R6 and also grounded through the seventh resistor R7. The drain of the third MOSFET Q3 is connected to the heating element 61, and the source of the third MOSFET Q3 is grounded. After the temperature is set by the control button 66, the PB3 pin of the temperature control chip U1 outputs a high level, which turns on the third MOSFET Q3 and causes the heating element 61 to heat up.
[0050] Of course, other heating elements can also be used in this invention, such as those found in existing feeding devices, as long as they can heat the gastric tube. This invention does not limit the type or structure of the heating element.
[0051] Please continue reading. Figure 1 The nipple 4 is provided with a head-locking rope 7, a fastening rope, or Velcro on both sides to help secure the nipple 4 and prevent it from falling off during use. The head-locking rope 7 or fastening rope is an elastic rope, which can better fit the newborn's face, ensure the stability of the nipple 4, and avoid causing pressure on the newborn, thus improving the comfort of use.
[0052] The nipple 4 has attachment portions 42 on both sides. A hydrocolloid is provided on the side of the attachment portion 42 that adheres to the newborn's face. The hydrocolloid has good adhesion, which helps to secure the nipple 4 and ensures it will not easily fall off during the newborn's sucking process. Furthermore, the hydrocolloid material is soft and will not cause allergic reactions to the newborn's delicate skin, ensuring safety and comfort during use.
[0053] The breast milk storage container 1 can be a rigid or flexible bottle to meet the needs of different usage scenarios. Rigid bottles have a sturdy structure, facilitating various operations by medical personnel, such as hanging and adding milk. Their stability and durability make them advantageous for frequent use, especially in professional medical environments such as hospitals. Flexible bottles have a degree of flexibility, with a rigid top design for easy opening and closing of the sealing cap 11 by medical personnel. This design combines the flexibility of flexible materials with the ease of operation of a rigid top, making it convenient to use, ensuring a tight seal, and facilitating storage and transportation. Furthermore, the breast milk storage container 1 can also use a milk storage bag; this invention does not limit the structure of the breast milk storage container.
[0054] In summary, the simplified partial nasogastric feeding device provided by this utility model includes a milk storage container, a milk delivery tube, a gastric tube, and a nipple. The two ends of the milk delivery tube are connected to the milk storage container and the nipple, respectively. The nipple contains a milk absorbent and has a breast milk inlet. One end of the gastric tube is connected to the milk storage container, and the other end is for feeding the newborn.
