Sampling device for uric acid determination liquid

Abstract

The invention provides a sampling device for uric acid determination liquid, and relates to the technical field of household medical instruments. The sampling device for the uric acid determination liquid comprises an outer cylinder, a connecting bag is fixedly connected to the inner surface of the outer cylinder, the left side of the connecting bag is an elastic end, the left side end of the elastic end is fixedly connected with a connecting frame, a puncture needle is fixedly connected into the connecting frame, and a motor is arranged on the inner wall of the outer cylinder and located on the upper portion of the puncture needle. Aseptic cotton and disinfectant flowing down from a thin film punctured through an ejector rod are adopted to conduct disinfection, a single detection person can complete operation, a puncture needle can stretch out by a proper length according to the body type of a patient under the control of the detection person, the opening size of a valve is changed through an adjusting wheel, and the venous blood drawing speed can be changed; during blood drawing, air in the sampling device is preferentially exhausted, the interference of the air in the sampling device on a blood sample can be avoided, and determination can be performed after 2 ml of venous blood is extracted, anticoagulation is not performed and serum is separated.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a sampling device for uric acid measuring liquid. Background technique [0002] Uric acid is the end product of purine metabolism in the human body, which is mainly produced by the decomposition of nucleic acid and other purine compounds decomposed by cell metabolism and purine in food through the action of enzymes. Disorders of uric acid metabolism often cause hyperuricemia. In the process of uric acid detection, 2ml of venous blood needs to be drawn, without anticoagulation, and the serum is separated for measurement. Before drawing venous blood, it is necessary to use a sterile cotton dipped in disinfectant to wipe the blood drawing area, and after the venous blood is drawn, it is necessary to press. The process requires inspectors to free up their hands to operate. People have different body shapes, and the needles of the current sampling devices are relatively fixe...
