Description

Neonate blood sampling fixer

Technical Field

The invention belongs to the technical field related to blood sampling of femoral arteries of newborns, and particularly relates to a blood sampling fixer for newborns.

Background

Neonatal diseases are one of the main diseases threatening children, and the incidence rates of neonatal asphyxia, neonatal ischemia-hypoxic encephalopathy and neonatal pulmonary transmembrane disease are also rare, and the disease condition is critical, so that the respiratory function, blood oxygen metabolism and the pH value of blood of a sick child need to be accurately judged, and arterial blood needs to be collected for examination of items such as blood gas analysis and the like. The placement and the positioning of the femoral artery blood sampling position play a decisive role in the success of blood sampling: the infant takes a horizontal position, takes off one trouser leg to enable the lower limb to be in a knee bending abduction position, if necessary, a small pillow is padded under the hip, an assistant fixes the two legs of the infant, the skin is disinfected conventionally, meanwhile, the index finger and the middle finger of the left hand of an operator are disinfected, the most obvious pulse position of the femoral artery is beaten and fixed, a right hand-held injector is inserted into the skin in a 90-degree or 45-degree needle insertion way, then the needle is gradually lifted upwards, 1ml of blood sample is extracted, the needle head is rapidly pulled out, a rubber plug is sleeved for testing, and a sterile cotton ball is immediately used for pressurizing a hemostasis point until no bleeding occurs.

The existing blood sampling fixing technology for the newborn has the following problems: the femoral artery blood sampling method is a main method for collecting blood samples of pediatric arteries, is widely applied to clinic, but years of clinical practice shows that the method has certain defects because the femoral artery is deep in position and complicated in anatomical part, and the crying and screaming of a patient are not matched and difficult to fix, and can be completed by two persons in cooperation, and if the femoral artery blood sampling method is not fixed well in the blood sampling process, blood drawing failure can be directly caused.
