Description

Technical Field

[0001] The utility model relates to the technical field of pediatrics, in particular to a pediatric infusion hand fixator. Background Art

[0002] Due to a series of factors such as children's relatively weak resistance, they are more likely to get sick, but oral medication is slow to work, so they are generally treated with intravenous drips. However, during the infusion process, children are active and have poor self-control, and cannot cooperate well, which can easily cause the needle to fall off or roll around during the infusion process, resulting in multiple needle sticks during one infusion, causing more pain to the child. In order to prevent the above phenomenon from happening, a fixing device is usually used to fix the child's palm during the infusion process, such as;

[0003] Authorization announcement number CN219783401U provides a hand fixator, which relates to the field of fixator technology and includes a base plate, a table plate fixed to the top outer wall of the base plate, an interdigital plate fixed to the top outer wall of the table plate, a vertical plate fixed to the bottom outer wall of the base plate, a fixing assembly fixed to the bottom outer wall of the vertical plate, a controller installed on one side outer wall of the fixing assembly, and stepper motors installed at both ends of the bottom outer wall of the base plate. The utility model can fix the device to the armrest of the patient's infusion chair through the fixing assembly. The patient can insert the hand that needs infusion between the pressure belt and the interdigital plate. At this time, the pressure sensor senses the pressure and transmits the signal to the controller. The controller controls the two stepper motors to drive the two cloth rollers to rotate in opposite directions respectively, and rewinds the pressure belt from both ends, so that the pressure belt is tightened and pressed against the patient's hand, thereby fixing the patient's hand automatically. There is no need for medical staff to perform manual strapping operations, which is more convenient and quick.
