Blood collecting and blood squeezing devices used for diagnosis of hereditary metabolic diseases of newborns

Abstract

The invention relates to blood collecting and blood squeezing devices used for diagnosis of hereditary metabolic diseases of newborns. In the blood collecting and blood squeezing devices used for thediagnosis of hereditary metabolic diseases of the newborns, a duckbill one-way valve is connected with a valve cap provided with internal threads through external threads; a blood inlet pipeline fixedly communicates with one side of a negative-pressure balloon body; a heparin cap is installed at an outer end of the blood inlet pipeline in threaded connection; a first blood outlet pipeline, a second blood outlet pipeline and a third blood outlet pipeline communicate with the other side of the negative-pressure balloon body; and medical one-way valves are installed at outer ends of all of the first blood outlet pipeline, the second blood outlet pipeline and the third blood outlet pipeline. After drawing of blood, the drawn blood is completely dropped onto three blood collection cards corresponding to three drops of blood at one time by the blood squeezing device, so that dropping operation of blood becomes controllable, rapid and highly efficient.

Description

technical field [0001] The invention relates to the field of medicine, in particular to a blood collection and blood squeezing device for diagnosis of neonatal genetic metabolic diseases. Background technique [0002] Metabolic disease is a disease caused by the accumulation or deficiency of certain metabolic substances such as sugar, fat, protein, purine, calcium and copper when the biochemical process in the body is impaired. Symptoms vary in severity, and the diagnosis depends on clinical manifestations and biochemical examinations such as blood and urine. The detection of genetic metabolic diseases refers to the detection of genetic metabolic diseases in newborns. It is a simple, fast and cheap blood spot test. Through this screening, it is possible to find out whether a child is suffering from a congenital genetic disease early, and to carry out timely treatment so that it can grow up healthily. Use equipment, medical reagents and specific biochemical medical detectio...

Problems solved by technology

[0003] In clinical practice, children's hospitals generally use blood collection cards that can drop three drops of blood for sampling operations. The blood of the child is dropped onto the blood collection card marked with relevant information such as name and gender. The traditional method uses a syringe to draw blood and then drops it on the blood collection card. On the card, this traditional method has certain defects: the traditional blood collection method needs to puncture the patient, and the process is cumbersome, and the operation is difficult and has a high coefficient of operation. , and directly taking blood with an intravenous syringe cannot meet the smooth and controllable dripping of blood, so there are certain defects in the traditional blood collection process; On the blood collection card for dripping blood, the process is operated by medical staff directly holding the syringe, and there are certain risks in the process. In addition to easily causing blood contamination, it is also likely to cause certain injuries to the operator. A little carelessness It will cause puncture needle injury, cause infection and unnecessary trouble, and cause waste of resources for disposable syringes, which also exerts a certain pressure on hospital recycling operations.

Therefore there is certain defect in the dripping out process of traditional blood
