A blood collection device for neonatal disease screening

Abstract

The invention discloses a newborn screening and blood sampling device. The newborn screening and blood sampling device is provided with dense blood suction holes. The blood is sucked in all directions, so that the blood suction speed is increased and the blood suction amount is guaranteed. The device is provided with a locating baffle and a fixing disc. A needle tip is fixed to the corium layer of the skin, so that the accuracy of the punctured position is improved, use is easy and convenient, speed is high, the needle tip is inserted into the skin accurately, the blood sampling amount is sufficient, and the blood sampling efficiency is high. A restorable medical rubber cavity on a blood storage cavity is pressed, a blood suction needle can be inserted into the body surface of a newborn baby, the blood suction needle is controlled by the locating baffle to be inserted into the portion with the proper depth, air in the restorable medical rubber cavity is exhausted, when the restorable medical rubber cavity is released by a medical worker, the blood suction needle is retracted out of the body surface of the newborn baby, and the restorable medical rubber cavity starts to suck the blood through the dense blood suction holes due to the intensity of pressure. The newborn screening and blood sampling device is convenient to use, high in speed, capable of allowing the needle tip to be accurately inserted into the skin, sufficient in blood sampling amount and high in blood sampling efficiency.

Description

Technical field [0001] The invention belongs to the technical field of medical devices, and particularly relates to a blood sampling device for neonatal disease screening. Background technique [0002] In medicine, newborns must be screened for diseases after birth. Neonatal disease screening refers to the use of rapid and sensitive laboratory methods in the newborn population to treat newborns with genetic metabolic diseases, congenital endocrine abnormalities and certain hazards. The general term for screening for serious genetic diseases. Its purpose is to enable early diagnosis and early treatment of sick newborns before clinical symptoms have not yet manifested or when their manifestations are mild, so as to prevent irreversible damage to body tissues and organs. Avoid mental retardation, serious illness or death of sick newborns. One aspect of neonatal disease screening is to take blood from the inside or outside of the heel three days after the baby is born, and use a blo...
