Description

Technical Field

[0001] The invention relates to the technical field of neonatal feeding, and in particular to a feeding device for a neonatal intensive care unit. Background Art

[0002] The neonatal intensive care unit is a medical area dedicated to monitoring and treating newborns who need special care after birth. In this unit, medical staff provide professional care around the clock, including monitoring the vital signs of newborns, providing respiratory support, adjusting drug therapy, etc. Operators in the neonatal intensive care unit often use neonatal feeding devices, which are devices used to provide food and nutrition to newborns. After the birth of the newborn, if they cannot be fed naturally, medical staff may use various feeding devices to meet their nutritional needs.

[0003] In the early stage after the birth of a newborn, liquid feeding is a common feeding method. Generally, the operator needs to use both hands to operate the liquid feeding device, because the mouth of the newborn is relatively small, and the newborn is unconscious during the feeding process, so the newborn may cry and stick out the tongue instinctively. During the crying and sticking out of the tongue, the liquid food will flow out of the newborn's mouth. In order to avoid this phenomenon, most operators will place a layer of tablecloth under the chin of the newborn, so that the fallen liquid food will drip on the tablecloth, and the tablecloth can be taken off after the feeding is over. However, during the feeding process, the tablecloth The cloth may fall off due to the shaking of the newborn, so the operator needs to reposition the table cloth, which will affect the operator's progress in feeding the newborn. In addition, the table cloth needs to be cleaned after use. If it is thrown away directly, it will cause a waste of resources. Some operators will set a collection structure on the outer surface of the feeding head, but the collection structure can only collect liquid food. Once there is too much liquid food inside the collection structure, the operator needs to clean or replace the collection structure, which will delay the operator's progress in feeding the newborn. Therefore, the present application provides a feeding device for a neonatal intensive care unit to meet the needs. Summary of the invention

[0004] The technical problem to be solved by the present invention is to provide a feeding device for a neonatal intensive care unit by setting a collection component, a negative pressure component, a driving component and a feeding component. The feeding component can not only open the liquid food channel on the lower surface of the storage tank to allow the liquid food to enter the feeding tube, but also prevent the liquid food in the storage tank from caking and blocking when entering the feeding tube. The driving component allows the push rod to slide intermittently under the cooperation of the gear and the push plate. The intermittent sliding setting of the push rod can not only prevent the liquid food from flowing all the time, causing the newborn to choke due to excessive liquid food in the mouth, but also prevent the phenomenon that the speed of the liquid food is not adjusted in time due to the operator's untimely operation, thereby further improving the safety when feeding the newborn. The collection component cooperates with the setting of the negative pressure component to allow the liquid food inside the branch pipe to flow into the collection tank. Such a setting can quickly and timely suck the liquid food collected by the collection cover, which can not only prevent the liquid food from being blocked in the collection cover and the branch pipe, but also the negative pressure setting does not need to add an additional driving structure. The above setting can solve the problem that the liquid food flows out of the mouth of the newborn during feeding, thereby causing liquid food waste and affecting the feeding progress.

[0044] like Figure 1-Figure 14As shown, an embodiment of the present invention provides a feeding device for a neonatal intensive care unit, comprising a feeding tube 1 and a hose 22, wherein the upper surface of the feeding tube 1 is fixedly connected to a storage tank 2, the upper surface of the storage tank 2 is rotatably connected to a cover 3, the inner surface of the feeding tube 1 is slidably connected to a push rod 10, the outer surface of the push rod 10 is fixedly connected to a sealing plug 11, the outer surface of the feeding tube 1 is provided with an exploration groove 8, the outer surface of the feeding tube 1 is provided with a fitting surface 20, the surface of the feeding tube 1 is fixedly connected to an infusion tube 9, one end of the hose 22 is fixedly connected to a connecting tube 21, the hose 22 and the infusion tube 9 are connected via the connecting tube 21, the end of the hose 22 away from the connecting tube 21 is fixedly connected to a feeding head 23, and the feeding tube 1 is fixedly connected to the feeding head 23. A collecting component is provided on the outer surface of the head 23, and the collecting component is used to collect liquid food flowing out from the mouth of the newborn or from the feeding head 23. The collecting component is connected to the feeding head 23. A negative pressure component is slidably connected to the lower surface of the feeding tube 1, and the negative pressure component is used to negatively pump the liquid food collected by the collecting component. The negative pressure component is connected to the feeding tube 1. A driving component is fixedly connected to the inner surface of the feeding tube 1, and the driving component is used to drive the push rod 10 to slide freely on the inner surface of the feeding tube 1. The driving component is respectively connected to the feeding tube 1 and the push rod 10. A feeding component is provided on the inner surface of the storage tank 2, and the feeding component is used to control the liquid food inside the storage tank 2 to enter the inside of the feeding tube 1. The feeding component is connected to the storage tank 2.

[0045] As an implementation method in this embodiment, Figure 1 , Figure 2 and Figure 5-Figure 7 As shown, the collecting component includes a collecting hood 24 inserted on the outer surface of the feeding head 23, a drainage groove 31 is formed on the inner surface of the collecting hood 24, and a branch pipe 26 is inserted on the lower surface of the collecting hood 24. Since the collecting hood 24 is arranged on the outer surface of the feeding head 23, and the arc-shaped structure of the collecting hood 24 can fit the contour of the face and mouth of the newborn, when the liquid food flows out of the newborn's mouth, the liquid food at the corners of the mouth and the chin will enter the drainage groove 31. Since the drainage groove 31 has its own inclination angle, the liquid food inside the drainage groove 31 will automatically flow into the branch pipe 26.

[0046] In this embodiment, if Figure 5-Figure 7 As shown, the outer surface of the collecting cover 24 is fixedly connected with an insert block 27, the surface of the insert block 27 is fixedly connected with a clamping block 28, and the surface of the feeding head 23 is provided with a slot 29. The feeding head 23 and the collecting cover 24 are connected by the insert block 27 and the slot 29. The insert block 27 can not only be inserted in the slot 29, but also the insert block 27 and the slot 29 can be automatically locked under the limiting action of the clamping block 28. Such an arrangement can improve the efficiency of the operator in disassembling and assembling the collecting cover 24.

[0047] In this embodiment, if Figure 1 and Figure 5As shown, the outer surface of the collecting hood 24 is provided with a wearing ring 25, and the outer surface of the collecting hood 24 is symmetrically installed with a snap ring 30. The wearing ring 25 and the collecting hood 24 are connected by the snap ring 30. The operator can selectively wear the wearing ring 25 to the outer surface of the collecting hood 24 through the snap ring 30. The wearing ring 25 is a soft belt with self-elasticity. When the wearing ring 25 is worn, the wearing ring 25 with an elastic structure can tighten the collecting hood 24. Such a setting can prevent the collecting hood 24 from fitting unstably and firmly to the newborn's face during feeding. If the newborn being fed is in a relatively stable mood, the operator can remove the wearing tube from the collecting hood 24.

[0048] In this embodiment, if Figure 5 and Figure 7 As shown, the collecting hood 24 is an arc-shaped structure that fits the facial shape of the newborn. A spacer ring 33 is fixedly connected to the inner surface of the collecting hood 24. The spacer ring 33 is installed at the connecting gap between the collecting hood 24 and the branch pipe 26. A fixing frame 34 is fixedly connected to the lower surface of the feeding tube 1. The negative pressure component is connected to the branch pipe 26. The surface area of ​​the bottom of the spacer ring 33 is slightly larger than the surface area of ​​the branch pipe 26. The purpose of this arrangement is to prevent the backflow of liquid food.

[0049] As an implementation method in this embodiment, Figure 9-14 As shown, the negative pressure assembly includes a collecting tank 35 slidably connected to the lower surface of the feeding tube 1, an air valve 40 is provided on the outer surface of the collecting tank 35, a negative pressure pipe 51 is inserted on the surface of the collecting tank 35, the collecting cover 24 and the collecting tank 35 are connected by a branch pipe 26, the outer surfaces of the branch pipe 26 and the negative pressure pipe 51 are fixedly connected with a sealing ring 32, a bottom cover 44 is provided on the lower surface of the collecting tank 35, a partition 41 is fixedly connected to the inner surface of the collecting tank 35, a notch 42 is provided on the surface of the partition 41, and a guide plate 43 is provided on the inner surface of the collecting tank 35. When the air valve 40 is opened, the negative pressure pipe 51 is inserted into the surface of the collecting tank 35, and the collecting cover 24 and the collecting tank 35 are connected by a branch pipe 26. The outer surfaces of the branch pipe 26 and the negative pressure pipe 51 are fixedly connected with a sealing ring 32. After opening, the branch pipe 26 and the collecting tank 35 will maintain air pressure connection. At this time, the liquid food inside the branch pipe 26 will flow into the collecting tank 35 under the action of negative pressure. The liquid food flowing into the collecting tank 35 will enter the upper surface of the guide plate 43 under the guidance of the partition 41 and the groove 42, and finally the liquid food will stay on the upper surfaces of the guide plate 43 and the bottom cover 44. Such a setting can quickly and timely suck the liquid food collected by the collecting cover 24, which can not only prevent the liquid food from being blocked in the collecting cover 24 and the branch pipe 26, but also the negative pressure setting does not require the addition of an additional driving structure.

[0050] In this embodiment, if Figure 9-12As shown, a slider 36 is fixedly connected to the upper surface of the collecting tank 35, a groove 37 is provided on the surface of the slider 36, a slide groove 38 is provided on the lower surface of the feeding tube 1, and a protrusion 39 is fixedly connected to the inner surface of the slide groove 38. The slider 36 can not only slide in the slide groove 38, but also the slide groove 38 can limit it. This arrangement is to facilitate the operator to disassemble and assemble the collecting tank 35. When the slider 36 slides to the end of the slide groove 38, the protrusion 39 will be snapped into the groove 37. This arrangement is to prevent the collecting tank 35 from slipping on the lower surface of the feeding tube 1.

[0051] In this embodiment, if Fig.13 and Fig.14 As shown, the upper surface of the bottom cover 44 is fixedly connected to the inner cover 46, the upper surface of the bottom cover 44 is fixedly connected to the sealing gasket 45, the lower surface of the collection tank 35 is provided with a sealing groove 47, the outer surface of the bottom cover 44 is slidably connected to the sliding cover 48, the surface of the sliding cover 48 is fixedly connected to the slide plate 49, and the surface of the bottom cover 44 is provided with a limiting groove 50. The sealing gasket 45 and the sealing groove 47 are provided to improve the sealing between the bottom cover 44 and the collection tank 35. Since the bottom cover 44 and the sliding cover 48 are connected by the limiting groove 50 and the slide plate 49, the sliding cover 48 can slide freely on the upper surface of the bottom cover 44. When the sliding cover 48 slides out a distance from the surface of the bottom cover 44, the operator can use the sliding cover 48 to remove the bottom cover 44 from the collection tank 35.

[0052] As an implementation method in this embodiment, Figure 2-Figure 4 As shown, the driving assembly includes a second motor 12 fixedly connected to the outer surface of the feeding tube 1, a second hood 19 fixedly connected to the outer surface of the feeding tube 1, a second rotating shaft 13 fixedly connected to the output end of the second motor 12, a gear 14 fixedly connected to the outer surface of the second rotating shaft 13, a smooth surface 15 provided on the outer surface of the gear 14, a driving shaft 16 inserted on the inner surface of the gear 14, a push plate 17 fixedly connected to the surface of the push rod 10, and a support frame 18 fixedly connected to the inner surface of the feeding tube 1. When the operator operates the driving assembly, the second motor 12 rotates, and the second motor 12 drives the The second shaft 13 rotates, and the gear 14 is driven to rotate during the rotation of the second shaft 13. The gear 14 rotates and cooperates with the tooth grooves on the surface of the push plate 17 to drive the push plate 17 to slide. When the smooth surface 15 on the surface of the gear 14 contacts the push plate 17, the push plate 17 will no longer be affected by the force of the gear 14 and will stop sliding until the tooth grooves on the surface of the gear 14 contact the push plate 17 again. The push plate 17 will continue to slide. During the sliding of the push plate 17, the support frame 18 can limit and support the push plate 17, thereby greatly improving the stability of the push plate 17 during the sliding process.

[0053] As an implementation method in this embodiment, Figure 2 and Figure 8 As shown, the feeding assembly includes a first motor 4 fixedly connected to the outer surface of the storage tank 2, the outer surface of the storage tank 2 is fixedly connected to a first hood 7, the output end of the first motor 4 is fixedly connected to a first rotating shaft 5, and the outer surface of the first rotating shaft 5 is fixedly connected to a valve paddle 6. When the operator operates the feeding assembly, the first motor 4 is started, and the first rotating shaft 5 is driven to rotate during the rotation of the output end of the first motor 4. During the rotation of the first rotating shaft 5, the valve paddle 6 will rotate with the first rotating shaft 5. During the rotation of the valve paddle 6, not only can the liquid food channel on the lower surface of the storage tank 2 be opened to allow the liquid food to enter the feeding tube 1, but also the valve paddle 6 can stir the liquid food during the rotation. The advantage of this arrangement is that it can prevent the liquid food in the storage tank 2 from caking and blocking when entering the feeding tube 1, and the rotary feeding method can facilitate the operator to control the flow rate of the liquid food entering the feeding tube 1.

[0054] The technical solution provided by the present invention is to set a collection component, a negative pressure component, a driving component and a feeding component. When in use, the lid on the top of the storage tank is first turned to open, and the liquid food to be fed is injected into the storage tank. After the liquid food is added, the lid is closed again. The operator can control the feeding component to allow the liquid food inside the storage tank to enter the feeding tube. When the newborn needs to be fed, the operator holds the feeding tube with one hand and takes the feeding head at the end of the hose with the other hand. Then, by holding the feeding tube, the operator controls the driving component to push the push rod toward the infusion tube. At this time, the liquid food inside the feeding tube will enter the hose along the infusion tube. When the liquid food in the hose is about to reach the feeding head, put the feeding head into the newborn's mouth, so that the liquid food will enter the newborn's mouth. After all the liquid food in the feeding tube has flowed out, the operator needs to take the feeding head out of the newborn's mouth first, and then control the driving component again to let the push rod slide in the opposite direction of the infusion tube. After the push rod moves to the initial position, the operator can re-control the feeding component to let the liquid food in the storage tank enter the feeding tube. After the liquid food enters the feeding tube, the operator can continue to operate the device to feed the newborn. After the feeding is completed, the operator takes the feeding head out of the newborn's mouth and the device ends.

[0055] The feeding assembly is arranged on the inner surface of the storage tank. When the operator operates the feeding assembly, the first motor is started. During the rotation of the output end of the first motor, the first rotating shaft is driven to rotate. During the rotation of the first rotating shaft, the valve paddle will rotate along with the first rotating shaft. During the rotation of the valve paddle, not only can the liquid food channel on the lower surface of the storage tank be opened to allow the liquid food to enter the feeding tube, but the liquid food can also be stirred during the rotation of the valve paddle. The advantage of this arrangement is that it can prevent the liquid food in the storage tank from agglomerating and blocking when entering the feeding tube, and the rotary feeding method can facilitate the operator to control the flow rate of liquid food entering the feeding tube.

[0056] When the operator operates the driving component, the second motor rotates, and the second shaft is driven to rotate during the rotation of the second motor. The gear is driven to rotate during the rotation of the second shaft. The gear rotates in cooperation with the tooth groove on the surface of the push plate to drive the push plate to slide. When the smooth surface of the gear surface contacts the push plate, the push plate will no longer be affected by the force of the gear and will stop sliding. The push plate will not continue to slide until the tooth groove on the gear surface contacts the push plate again. Therefore, the reciprocating push rod will slide intermittently under the cooperation of the gear and the push plate. The advantage of the intermittent sliding setting of the push rod is that the liquid food inside the feeding tube will be intermittently pushed to flow intermittently during the intermittent sliding of the push rod, so that the liquid food flowing into the mouth of the newborn will not It will always be in a flowing state. The intermittent stop time of the liquid food can give the newborn time to swallow and react, thereby preventing the liquid food from flowing all the time and causing the newborn to choke due to too much liquid food in the mouth. This setting also simulates the scene of a newborn sucking breast milk. When sucking breast milk, the newborn sucks in an intermittent manner of stopping and sucking. Therefore, the setting of intermittent feeding of liquid food can further improve the comfort and intimacy of the newborn when swallowing liquid food, and the intermittent sliding push rod can give the operator more time to react and operate to adjust the speed of the liquid food flow. This setting can prevent the phenomenon that the speed of the liquid food is not adjusted in time due to the operator's untimely operation, thereby further improving the safety when feeding the newborn.

[0057] When the operator feeds the newborn, liquid food flows out from the feeding head. Since the newborn is unconscious during the feeding process, the newborn may cry and stick out the tongue instinctively. During the crying and sticking out of the tongue, liquid food will flow out of the newborn's mouth. Since the collection cover is arranged on the outer surface of the feeding head, and the arc-shaped structure of the collection cover can fit the contour of the newborn's face and mouth, when the liquid food flows out of the newborn's mouth, the liquid food at the corners of the mouth and the chin will enter the drainage trough. Since the drainage trough has its own tilt angle, the liquid food inside the drainage trough will automatically flow into the branch pipe, and the connection seam between the branch pipe and the collection cover A spacer is set at the gap, and the surface area of ​​the bottom of the spacer is slightly larger than the surface area of ​​the branch tube. The purpose of this setting is to prevent the backflow of liquid food. In addition, a clamping ring is also set on the outer surface of the collecting cover. The operator can selectively wear the wearing ring to the outer surface of the collecting cover through the clamping ring according to actual conditions. The wearing ring is a soft belt with self-elasticity. When the wearing ring is worn, the wearing ring with an elastic structure can tighten the collecting cover. This setting can prevent the collecting cover from fitting unstably and firmly to the newborn's face during feeding. If the newborn is in a stable mood during feeding, the operator can remove the wearing tube from the collecting cover.

[0058] In the process of the driving component pushing the push rod to slide in the feeding tube, a negative pressure chamber will be formed inside the feeding tube. This negative pressure chamber will become larger and larger as the push rod slides, and the negative pressure tube on the surface of the collecting tank is inserted into the negative pressure chamber inside the feeding tube. When the operator drives the push rod to slide to feed the newborn, a negative pressure chamber will also be formed in the feeding tube. During the feeding process, the liquid food collected by the collecting cover will flow into the branch tube. The operator can open the air valve inside the collecting tank to keep the branch tube and the collecting tank connected in terms of air pressure. At this time, under the action of negative pressure, the liquid food inside the branch tube will flow into the collecting tank, and the liquid food flowing into the collecting tank will enter the upper surface of the guide plate under the guidance of the partition and the groove, and finally the liquid food will stay on the upper surface of the guide plate and the inner cover. Such a setting can quickly and timely suck the liquid food collected by the collecting cover, which can not only prevent the liquid food from being blocked in the collecting cover and the branch tube, but also the negative pressure setting does not require an additional driving structure.

[0059] Since the branch pipe and the negative pressure pipe are connected to other structures by plugging, and the collection cover and the collection tank can be removed from the device, such a setting can facilitate the user to quickly disassemble and assemble the collection component and the negative pressure component, and the removed collection component can be directly cleaned and disinfected. After the collection tank is removed, the operator can slide the slide cover on the outer surface of the bottom cover to slide out a distance from one end of the bottom cover, and then the operator uses the slide cover to remove the bottom cover from the lower surface of the collection tank. After the bottom cover is removed, the operator can not only centrally process the liquid food collected in the collection tank, but also it is much more convenient to clean the collection tank after the liquid food processing is completed.
