Description

Technical Field

[0001] This invention belongs to the field of medication feeding equipment, specifically a medication feeding device for infants and young children with quantitative control, speed control, and anti-choking. Background Technology

[0002] Infants and young children have underdeveloped bodily functions, weak swallowing reflexes, and narrow oral and pharyngeal airways. They have extremely low tolerance for the rate and dosage of medication administration, making them a key group requiring protection in pediatric care. Currently, most commercially available medication administration devices for infants and young children are simple droppers, push-type feeders, or feeding spoons—traditional structures with simple overall designs and limited functionality, presenting significant shortcomings in actual medication administration. Traditional medication administration devices cannot precisely control the flow rate and speed of medication delivery, relying entirely on manual manipulation of the pushing force and speed. This results in significant human error and poor controllability, easily leading to situations where large amounts of medication are released instantaneously or the flow rate is too fast. Furthermore, existing devices struggle to achieve precise quantitative dosing, relying heavily on manual estimation of dosage using visual markings, resulting in low dosage accuracy and the potential for over- or under-dosing. When medication enters an infant's mouth rapidly and in large quantities, the infant may not be able to swallow in time, easily causing reflux, choking, or aspiration. These situations can range from mild crying and resistance to failed medication delivery, and more serious respiratory irritation leading to coughing, suffocation, and other safety hazards, severely impacting medication safety and therapeutic efficacy. These devices fail to meet the modern infant and toddler's needs for precise, safe, and stable medication administration. Summary of the Invention

[0019] Depend on Figures 3-4 As shown, the end connection component 9 includes two connecting sleeves 91, which are respectively installed inside the two limiting grooves 77. The top and bottom ends of the connecting sleeves 91 corresponding to the liquid inlet 79 are respectively fixedly installed with a fixing rod 93 and a bottom tube 92. The fixing rod 93 is fixedly connected to the inner top wall of the drug inlet chamber 5.

The top end of the bottle body 1 is fixedly installed with an n-shaped tube 94, wherein the end of the n-shaped tube 94 away from the drug feeding nozzle 2 is connected to the top end of the top tube 95. The connecting sleeve 91 includes a ring sleeve 911, which is fitted and installed on the outside of the rotating block 74. Two limiting rings 76 limit the two sides of the ring sleeve 911. An annular cavity 912 is opened inside the ring sleeve 911. An inner rotating sealing ring 913 is installed on the inner wall of the ring sleeve 911.

[0020] Depend on Figure 5 The position adjustment assembly 8 includes a piston partition 81 installed outside the rotating shaft 71. The piston partition 81 divides the drug inlet chamber 5 into a drug mixing chamber and a drug delivery chamber. The movement of the piston partition 81 controls the connection position of the end of the n-shaped tube 94, allowing the drug to circulate within the drug mixing chamber for uniform drug distribution and facilitating drug delivery to the drug delivery chamber. The piston partition 81 is located between the spiral feeding plate 73 and the rotating block 74. Circumferential rotating sealing rings 82 are installed on both the inner and outer walls of the piston partition 81, respectively, and are tightly fitted to the inner wall of the drug inlet chamber 5 and the outer wall of the rotating shaft 71. Guide rods 83 are symmetrically installed on the side of the piston partition 81 away from the feeding nozzle 2. A connecting plate 84 is movably installed inside the mounting cavity 6, and the connecting plate 84 is fixedly connected to the ends of the two guide rods 83. The guide rods 83 are slidably connected to the fixed partition, and a sealing gasket is provided on the outside of the guide rods 83. A screw 85 is rotatably installed inside the mounting cavity 6. The screw 85 is parallel to the guide rod 83 and is threadedly connected to the connecting plate 84. A driven gear 86 is coaxially mounted on one end of the screw 85. A driving gear 87 is meshed above the driven gear 86. The driving gear 87 is fixedly connected to the output shaft of the second motor 88. The second motor 88 is installed inside the mounting cavity 6. The output shaft speed of the first motor 72 and the output shaft speed of the second motor 88 are controlled by the control component 10. The rotating shaft 71 drives the spiral feeding plate 73 to rotate in the feeding nozzle 2 to realize drug dispensing. In addition, the piston partition 81 moves towards the feeding nozzle 2, causing the liquid level of the drug in the drug dispensing cavity to rise continuously, facilitating the discharge of the drug with the spiral feeding plate 73 and facilitating complete drug dispensing. At the same time, the piston partition 81 moves so that the end of the n-shaped tube 94 near the feeding nozzle 2 is connected to the drug mixing cavity, and at the same time drives the rotating block 74 to rotate, so that the stirring plate 75 stirs the drug evenly. The impeller 711 drives the drug to circulate in the drug mixing cavity, improving the uniformity of the drug.

[0021] Depend on Figure 8The control unit 10 includes a control panel 1001, a feeding speed control button 1002, a feeding volume control button 1003, a first on / off button 1004, and a second on / off button 1005, all mounted on the bottle body 1. The control panel 1001 displays the output shaft speed of the first motor 72 and the output shaft speed of the second motor 88, and simultaneously controls the rotation direction of the output shaft of the second motor 88. Both the first motor 72 and the second motor 88 are externally connected to rheostats. The feeding speed control button 1002 and the feeding volume control button 1003 adjust the resistance values ​​of the two rheostats, thereby controlling the output shaft speed of the first motor 72 and the second motor 88. The output shaft speed of motor 88 is adjusted. The first on / off button 1004 and the second on / off button 1005 are used to control the on / off of the first motor 72 and the second motor 88, respectively. Both the first motor 72 and the second motor 88 are connected to external rheostats, which facilitates the adjustment of the output shaft speed of the first motor 72 and the rotation speed of the spiral feeding plate 73, thereby controlling the feeding speed. The output shaft adjustment of the second motor 88 is used to adjust the moving speed of the piston partition 81 and the rising speed of the liquid level in the feeding output chamber, thereby controlling the amount of liquid output driven by the spiral feeding plate 73 per unit time, thus realizing quantitative feeding, speed control and anti-choking.

[0022] Working principle: The piston baffle 81 set in the drug inlet chamber 5 sets the drug mixing chamber and the drug delivery chamber on both sides of the piston baffle 81 respectively. The drug delivery chamber is set close to the drug delivery nozzle 2. When in use, the top cover 4 on the drug inlet tube 3 is unscrewed, and then the medicine needed by the infant is passed from the drug inlet tube 3 into the drug mixing chamber. The drug inlet chamber 5 is axially set as transparent glass for easy observation by the user. Then, the second motor 88 is turned on by the second start / stop button 1005. The screw 85 is driven to rotate by the drive gear 87 and the driven gear 86, which in turn drives the piston partition 81 to move towards the feeding nozzle 2 until the end of the n-shaped tube 94 near the feeding nozzle 2 also enters the drug mixing chamber. The second motor 88 is then turned off. Then, the first motor 72 is turned on by the first start / stop button 1004, which drives the rotating shaft 71 to rotate, which in turn drives the rotating block 74 to rotate. This causes the stirring plate 75 to mix and stir the drug, making it more uniform. In addition, the rotation of the rotating block 74 drives the medium to flow through the impeller 711, which drives the drug to enter the first connecting sleeve 91 from the bottom tube 92, then enters the flow chamber 78 from the liquid inlet 79, and then enters the second connecting sleeve 91 from the liquid outlet 710. Finally, the drug flows back into the drug mixing chamber through the top tube 95 and the n-shaped tube 94, so that the drug continuously circulates in the drug mixing chamber, improving the uniformity of drug mixing. After achieving uniform mixing, the output shaft rotation direction of the second motor 88 is changed by the control panel 1001, thereby driving the piston partition 81 to move away from the feeding nozzle 2 until the end of the n-shaped tube 94 near the feeding nozzle 2 is connected to the feeding output chamber. Then, the first motor 72 is turned on again to drive the drug in the drug mixing chamber to continuously enter the feeding output chamber through the n-shaped tube 94 until the drug is completely entered into the feeding output chamber. Then, the rotating shaft 71 drives the spiral medicine delivery plate 73 to rotate. In addition, the second motor 88 drives the piston partition 81 to move towards the medicine feeding nozzle 2, continuously reducing the space of the medicine output chamber and causing the liquid level of the medicine in the medicine output chamber to rise above the end of the medicine feeding nozzle 2. At this time, the rotating spiral medicine delivery plate 73 continuously drives some medicine to be discharged towards the discharge end of the medicine feeding nozzle 2. At the same time, the discharge end of the medicine feeding nozzle 2 is inserted into the infant's mouth to achieve medicine feeding. Both the first motor 72 and the second motor 88 are externally connected to rheostats. The feeding speed control button 1002 and the feeding quantity control button 1003 adjust the resistance values ​​of the two rheostats, thereby adjusting the output shaft speeds of the first motor 72 and the second motor 88. After adjusting the output shaft speed of the first motor 72 by the feeding speed control button 1002, the rotation speed of the spiral feeding plate 73 is adjusted, thereby controlling the feeding speed. After adjusting the rotation of the output shaft of the second motor 88 by the feeding quantity control button 1003, the moving speed of the piston partition 81 is adjusted, thereby adjusting the rising speed of the liquid level in the feeding output chamber, and thus controlling the amount of liquid output by the spiral feeding plate 73 per unit time, thereby achieving quantitative feeding, speed control, and anti-choking.
