Description

Technical Field

[0001] The utility model relates to the technical field of medical auxiliary appliances, in particular to a newborn incubator gravity feeding auxiliary device. Background Art

[0002] Clinically, newborns, especially premature infants, often require a period of feeding observation in an incubator after birth. Due to premature birth or illness, some newborns are temporarily unable to receive full oral feeding and require gravity feeding via a feeding device through a gastric tube to ensure adequate nutrition. Therefore, the development of gravity feeding assist devices for incubators is of great significance for neonatal care.

[0003] At present, clinical scholars have conducted relevant research. For example, the patent with authorization announcement number CN215350209U discloses a neonatal incubator gravity feeding assist device, including an L-shaped frame, and adsorption fixing components are provided in the middle of the top and the middle of the left side of the L-shaped frame. A slope corner inclined at 45° is provided at the connection between the longitudinal part and the transverse part of the L-shaped frame, and two groups of suspensions are symmetrically provided at the middle of the bottom end of the slope corner. Two groups of rotating sleeves are symmetrically provided at the inner ends facing each other of the two groups of suspensions, and the inner ends of the rotating sleeves are rotatably connected to cross arms. The inner ends of the two groups of cross arms are fixedly connected to syringe barrels, and a heating component is provided on the syringe barrel. A connecting nozzle is provided at the bottom end of the syringe barrel, and a manual control valve is provided on the connecting nozzle. The above-mentioned utility model can fix the entire device on the side wall and top wall of the incubator for use by setting two groups of adsorption fixing components.

[0004] However, the existing technology still has the following shortcomings during use and requires improvement. First, the existing technology cannot effectively adapt to incubators of different specifications. Specifically, the above-mentioned device requires the top and sides of the incubator to be relatively flat so that the suction cups at both ends of the L-shaped frame can be stably fixed to the incubator. Furthermore, the position of the feeding container is fixed and cannot be adjusted after the device is fixed. However, newborns often move inside the incubator, and to ensure effective feeding, the position of the feeding container must be adjusted according to the newborn's position. In view of the above situation, the present utility model is specially proposed. Utility Model Content

[0030] The working principle of a gravity feeding auxiliary device for a neonatal incubator in an embodiment of the present application is as follows: when it is necessary to feed the newborn inside the incubator, the device is placed inside the incubator and the vertical shaft 7 and the screw rod 11 are rotated at the same time. The screw rod 11 drives the threaded sleeve 12 to move to both sides, and the threaded sleeve 12 pushes the end of the supporting cross column 1 toward the inner wall of the incubator. The rotation of the vertical shaft 7 causes the spur gear 16 to drive the two rectangular racks 15 on both sides to move toward the two ends of the power box 8. The rectangular rack 15 drives the front end of the supporting cross column 1 to move toward the inner wall of the incubator through the moving rod 6. After the rubber suction cup 14 on the side of the supporting cross column 1 is tightly adsorbed with the inner wall of the incubator, the threaded sleeve 12 drives the rubber suction cup 14 at one end of the supporting cross column 1 to contact the side wall of the incubator through the squeezing of the threaded sleeve 12 and the rectangular rack 15. The rectangular rack 15 moves to both sides at the same time under the action of the spur gear 16, driving the two ends of the supporting cross column 1 at the other end The rubber suction cup 14 on the side is close to the inner wall of the incubator, and the screw rod 11 drives the threaded sleeve 12 to squeeze the rubber suction cup 14 toward the inner wall of the incubator, and the rectangular rack 15 drives the rubber suction cup 14 to squeeze toward the inner wall of the incubator at the same time through the moving rod 6; the two ends of the supporting horizontal column 1 of the utility model move to both sides through two different movement modes, and the spur gear 16 at one end cooperates with the rectangular rack 15 to have a self-locking function, so that it can be installed smoothly without too much support during installation to prevent tilting; the screw rod 11 at the other end takes up less space; the utility model can be stably fixed above the inner wall of the incubator, and the feeding container is placed inside the scale tube 19. The left and right positions are adjusted by sliding the movable frame 3 on the surface of the extension shaft 10, and the longitudinal position is adjusted by sliding the sliding frame 2 on the inner wall of the slide groove 13, so as to adjust the specific position of the feeding auxiliary device according to the position of the newborn and avoid excessive movement of the newborn inside.
