Description

Paediatrics blood sampling device

Technical Field

The utility model relates to a blood sampling device especially relates to a paediatrics blood sampling device.

Background

Paediatrics blood sampling is different from general blood sampling, and considering that the blood sampling object is the infant, so can appear many unexpected situations in the blood sampling engineering. At present, when a hospital takes blood for children, the arms of the children need to be fixed, and blood samples at the tips of fingers can be collected usually.

The infant has fear psychology to the hospital, is unwilling to accept any examination in the hospitalization process, and is even unwilling to accept invasive treatment and nursing. Especially to the blood sampling, children usually can have the feared psychology, can't cooperate the work, probably leads to the blood sampling unsmooth.

Moreover, infant finger tip blood circulation is relatively poor, and in addition infant's uncooperative with struggle, after the puncture, the blood of finger tip is difficult to extract, needs medical personnel manual extrusion infant's finger to make its blood smooth, this psychological burden and the fear mood that has more aggravated infant.

In summary, in order to alleviate the fear of the infant in the blood sampling process, it is urgently needed to provide a blood sampling device which is convenient and easy to operate.

SUMMERY OF THE UTILITY MODEL

In order to solve the above problems, the present application provides a pediatric blood collection device.

The pediatric blood sampling device comprises a supporting table 1, wherein one end of the supporting table 1 is provided with an arm fixing device 2, the other end of the supporting table 1 is provided with a finger fixing device 4, a shielding plate 3 is arranged between the arm fixing device 2 and the finger fixing device 4, and the shielding plate 3 allows an arm to pass through; in one embodiment, a through hole 301 is provided between the shutter 3 and the support table 1 to allow an arm to pass through.
