Vacuum blood collecting tube capable of directly separating blood serum and method for directly separating blood serum

Abstract

The invention relates to the technical field of a clinical medical equipment, and particularly relates to a vacuum blood collecting tube capable of directly separating blood serum and a method for directly separating blood serum. The vacuum blood collecting tube comprises a blood collecting tube body, an inner tube, a rubber plug and a filter core. The vacuum blood collecting tube is characterized in that the inner tube of the blood collecting tube is arranged inside the blood collecting tube body; the rubber plug is arranged at the top part of the blood collecting tube body; the rubber plug is in structure similar to the shape of a plug shape; the upper center of the rubber plug structure is provided with a semicircle groove; left and right ends of the lower part of the rubber plug are embedded into the blood collecting tube body and connected with the inner tube of the blood collecting tube; a blood serum outfall is arranged at the bottom middle part of the inner tube of the blood collecting tube; a blood serum collecting room is arranged at the lower part of the blood serum outfall; a filter film is arranged at the upper part of the blood serum outfall on the inner tube of the blood collecting tube; the filter core is arranged at the upper part of the filter film, and a buffer plate is also arranged on the filter core, so as to form the blood collecting room in the inner tube of the blood collecting tube, and a layer of coagulation accelerator is arranged on the inner wall of the inner tube of the blood collecting tube. According to the invention, by utilizing the physical shape difference of a visible component of the blood and a blood serum component, the blood serum can be rapidly separated, and the method is simple, safe and fast.

Description

[technical field] [0001] The invention relates to the technical field of clinical medical devices, in particular to a vacuum blood collection tube capable of directly separating serum and a method thereof. [Background technique] [0002] The detection of blood samples is a routine technical means of clinical testing in medical institutions. The blood samples used for in vitro diagnosis are mainly divided into arterial blood and venous blood. Quite extensive, such as detection of biochemical indicators, hemagglutination indicators, blood rheology indicators, blood routine analysis, trace element and ion component analysis, nutritional component testing, drug concentration testing, genetic testing, infectious disease etiology testing, microbial detection and so on. Due to the differences in the detection instruments used for different detection indicators, venous blood samples are divided into three categories: serum, plasma and whole blood according to their purposes. Serum...
