Capsule blood collection device for detecting genetic metabolic disease

Abstract

The invention relates to a capsular blood collection device for detecting genetic metabolic disease. A negative-pressure airbag is provided with a joint, a sealing ring sheet is fixedly installed in the joint, an output tube is fixedly set in the sealing ring sheet, one end of the output tube communicates with the negative-pressure airbag through the sealing ring sheet, the other end of the outputtube is connected to an output unidirectional output valve provided on the outside of the joint, and a venous blood-collection needle insertion limit port is installed is fixed at the outer end of the seal ring sheet on the output unidirectional output valve; and the whole process is highly controllable. After the blood is drawn, the blood can be dripped onto a three-drop blood collection card, the blood dropping operation can be controlled, and the blood collection volume can meet the smooth and controllable dropping of blood, which can replace the traditional syringe to draw blood.

Description

technical field [0001] The invention relates to the field of medicine, in particular to a special capsule blood collection device for detecting 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 detection methods to ass...

Problems solved by technology

This traditional method has certain defects: First, the process of using a syringe to collect blood requires puncturing the patient and drawing a certain amount of blood. After clinical practice, it was found that the blood requirement for a blood collection card with three drops of blood is 1 ml. When blood is drawn through a syringe, it is often difficult to control, resulting in too much blood being drawn, resulting in unnecessary waste; secondly, the process of using a syringe to draw blood is also more troublesome, and the operation is difficult and has a high coefficient of operation, which cannot be used like disposable venous blood. It is as easy to operate as drawing blood with a needle, but directly taking blood with an intravenous syringe cannot meet the smooth and controllable dripping of blood, so the traditional method is currently using a syringe to draw blood; Drop the drawn blood onto the blood collection card with three drops of blood. This process is performed by the medical staff directly holding the syringe. The process also has certain risks. In addition to easily causing blood contamination, it is also likely to cause certain harm to the operator. A little carelessness will cause puncture needle injury, causing infection and unnecessary troubles, and at the same time causing waste of resources for disposable syringes, which also exerts a certain pressure on hospital recycling operations
