Description

Technical Field

[0001] This utility model relates to the field of newborn care technology, and in particular to a center positioning device for an infant radiant warming lamp head. Background Technology

[0002] Infant radiant warmers are primarily used for the auxiliary resuscitation of critically ill newborns and for neonatal care. They are widely used in NICUs, maternity wards, and maternity rooms to provide a constant bed surface temperature for the infant's care or treatment. The bed surface temperature of the infant radiant warmer is generated by a lamp head directly above it (consisting of a heating element and a lampshade; the heat emitted by the heating element is reflected by the lampshade). When medical staff perform auxiliary treatments on the infant (such as taking an X-ray), the lamp head needs to be temporarily rotated away from the bed surface, and then rotated back above the bed surface after the examination is completed.

[0003] Currently, most radiant warmer lamps for infants come in two types: fixed and rotating. The existing fixed lamp head is directly fixed at a certain height above the bed surface. This type of lamp head cannot be moved, making it unsuitable for clinical situations requiring temporary removal for auxiliary treatment; medical staff must manually move it away. While the existing rotating lamp head can be rotated away for auxiliary treatment, it has the drawback of not being able to completely return to its original position after being moved. It is difficult to accurately align the lamp head precisely above the center of the bed surface. If the lamp head is not directly above the center of the bed surface, it will affect the uniformity of the bed temperature, thus adversely affecting the infant. Summary of the Invention

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by providing a center positioning device for the head of an infant radiant warming table lamp.

[0005] To achieve the above objectives, the present invention can adopt the following technical solution:

[0006] The baby radiant warmer lamp head center positioning device of this utility model includes a fixing plate installed on the upper end of the baby radiant warmer column, and a rotating plate fixed on the lower surface of the baby radiant warmer lamp head and attached to the upper surface of the fixing plate; a through hole is formed on the fixing plate, and a rotating column passing through the through hole is vertically arranged on the rotating plate; a semi-circular arc structure rotating limiting groove is provided on the fixing plate on one side of the through hole, the center of the rotating limiting groove is consistent with the center of the through hole, and a pair of reset holes are provided on the other side of the through hole opposite to the rotating limiting groove; a limiting column sliding along the rotating limiting groove and a pair of reset balls that are adapted to and engaged with the reset holes are provided on the bottom surface of the rotating plate.

[0007] Furthermore, to ensure that the lamp head of the baby radiant warming table can rotate stably, a damping pad fitted on the rotating column should be provided between the mating surfaces of the fixed plate and the rotating plate.

[0008] Furthermore, to prevent the rotating column from coming out of the hole, a locking nut should be screwed onto the protruding end of the rotating column, and a pressure bearing and an anti-loosening washer should be sequentially installed on the rotating column between the locking nut and the fixing plate from top to bottom to prevent the locking nut from loosening and falling off due to long-term rotation of the rotating column.

[0009] The advantages of this invention lie in its simple overall structure, easy installation and operation, convenient maintenance, and suitability for mass production. Through the interlocking of the rotating column and the perforated insert, the connection between the rotating plate and the fixed plate is easily achieved, enabling the horizontal rotation of the baby radiant warmer lamp head on the baby radiant warmer table column. This facilitates the quick rotation of the lamp head away from the bed surface during auxiliary treatment by medical staff, and also allows for quick repositioning after the auxiliary treatment. Furthermore, the rotation limiting groove and reset hole on the fixed plate, along with the limiting column and reset ball on the rotating plate, easily limit the rotation angle of the baby radiant warmer lamp head and fix it after repositioning. This ensures that the lamp head is directly above the crib surface after repositioning, meeting the needs of clinical care and treatment while maintaining the temperature uniformity of the crib surface and preventing adverse effects on the child from inaccurate repositioning of the lamp head after auxiliary treatment.

[0013] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0014] like Figure 1-3 As shown, the baby radiant warmer lamp head center positioning device of this utility model includes a fixing plate 1 installed on the upper end of the baby radiant warmer column 100, and a rotating plate 2 fixed on the lower surface of the baby radiant warmer lamp head 200.

[0015] Specifically, the upper surface of the fixed plate 1 is attached to the lower surface of the rotating plate 2. A circular perforation 3 is formed on the fixed plate 1. A rotating column 4 is vertically installed on the rotating plate 2, passing through the perforation 3. Through the insertion and fitting of the rotating column 4 and the perforation 3, the rotating plate 2 and the fixed plate 1 are easily assembled, allowing the baby radiant warmer lamp head 200 to be installed on the baby radiant warmer column 100. This enables the baby radiant warmer lamp head 200 to rotate horizontally on the baby radiant warmer column 100, facilitating the quick rotation of the baby radiant warmer lamp head 200 away from the bed surface when medical staff provide auxiliary treatment to the child. In addition, a locking nut 5 is screwed onto the end of the rotating column 4 that passes downward through the perforation 3. A pressure bearing 6 and an anti-loosening washer 7 are sequentially installed from top to bottom on the rotating column 4 between the locking nut 5 and the fixed plate 1. This ensures that the rotating column 4 will not come out of the perforation 3 and prevents the locking nut 5 from loosening and falling off due to long-term rotation of the rotating column 4. Furthermore, to ensure that the baby radiant warming lamp head 200 can rotate stably, a damping pad 8 fitted on the rotating column 4 should be sandwiched between the mating surfaces of the fixed plate 1 and the rotating plate 2. This will give the baby radiant warming lamp head 200 a damping feel when rotating horizontally, making the rotation more stable.

[0016] A rotating limiting groove 9 is provided on the fixing plate 1 on one side of the perforation 3. On the other side of the perforation 3 opposite to the rotating limiting groove 9, a pair of reset holes 10 are also provided. The rotating limiting groove 9 is a semi-circular arc structure, and its center is consistent with the center of the perforation 3. The reset holes 10 are recessed blind holes. Correspondingly, a limiting post 11 that slides along the rotating limiting groove 9 and a pair of reset balls 12 that are adapted to and engaged with the reset holes 10 are provided on the bottom surface of the rotating plate 2. The reset balls 12 are composed of a top support spring that is vertically fixed on the rotating plate 2 and a ball body fixed to the lower end of the top support spring. When the baby radiant warming lamp head 200 is directly above the center of the bed surface, i.e., in its initial position, the two reset beads 12 are precisely fitted and secured in the two reset holes 10, and at this time, the limiting post 11 is located in the middle position of the rotating limiting groove 9. When the baby radiant warming lamp head 200 rotates horizontally to any side, the two reset beads 12 will disengage from the two reset holes 10, thereby easily achieving horizontal rotation of the baby radiant warming lamp head 200 under the guiding action of the limiting post 11 and the rotating limiting groove 9. This allows the baby radiant warming lamp head 200 to rotate away from the bed surface to avoid obstacles when medical staff provide auxiliary treatment to the child.

[0017] The rotating limiting groove 9 and reset hole 10 set on the fixed plate 1, together with the limiting post 11 and reset ball 12 set on the rotating plate 2, can easily limit the rotation angle of the baby radiant warming lamp head 200 and fix it after reset. This ensures that the baby radiant warming lamp head 200 is directly above the crib surface after reset, which not only meets the needs of clinical care and treatment, but also ensures the temperature uniformity of the crib surface. It also avoids the adverse effects on the child caused by the baby radiant warming lamp head 200 not being accurately reset after auxiliary treatment. In addition, the overall structure of the entire baby radiant warming lamp head center positioning device is relatively simple, easy to install and operate, and convenient for later maintenance, making it suitable for mass production.

[0018] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in this utility model embodiment are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.
