Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, in particular to an auxiliary device for blood sampling for infants. Background Art

[0002] Skin blood collection was once called capillary blood collection. It is a mixed blood collected from arterioles, venules and capillaries, which also contains intercellular matrix and intracellular fluid. Finger blood collection is easy to operate and the test results are relatively constant. Usually this blood collection method can be used for adults without any problems. However, for infants or children, it is often difficult to complete the task smoothly due to the nervousness or lack of cooperation of the infants or children. Auxiliary devices are needed to limit the infants' arms to a certain extent.

[0003] Some of the current auxiliary devices for blood drawing from young children usually use methods such as strapping and clamping to limit the child's arms, but there are certain requirements for the tightness of the restriction. If it is loose, the child may break free, and if it is too tight, the child's struggle may cause marks and abrasions on the arm skin. Utility Model Content
