Small device for blood type detection and detection method

Abstract

The invention discloses a small device for blood type detection, which utilizes a micro direct current motor to drive a bar-shaped magnet fixed on a rotating shaft of a micro direct current motor to rotate, iron beads in a microwell plate are driven via magnetic force to rotate, so that reagents and cells in the microwell plate are fully and uniformly mixed, and micro-centrifugation effect is achieved. The device does not need to be connected with an alternating-current power supply, and can be used for detecting various blood type systems such as ABO, Rh and the like; the device is suitable for being used in environments without large instruments or power supplies, such as field operations, sudden public health events, mobile laboratories and the like. According to a blood type detectionmethod, plasma and red blood cells are rapidly separated by using a filter, blood type detection is carried out by using a microporous plate as a carrier, and antigen and antibody reactions are promoted through rotation of iron beads. The microwell plate can be capped and sealed; compared with an existing detection method from the aspect of biosafety, the blood type detection method is advantageous in that aerosol does not overflow in a detection and interpretation process, especially in some infectious disease epidemic periods; workers can be efficiently protected against harm of pathogenic microorganisms via the small device for blood type detection and the blood type detection method..

Description

technical field [0001] The invention relates to a small device and a detection method for blood type detection, belonging to the technical field of medical detection. Background technique [0002] At present, blood typing is mainly based on serological detection, and the detection methods mainly include slide method, test tube method, and microcolumn gel method. [0003] The slide method is mainly used for blood type screening because it can only detect positive antigens. The operation method is to drop IgM anti-A, anti-B, anti-D and other blood typing reagents on the blood type identification slide, then add the diluted red blood cell suspension to be tested respectively, mix well and shake the slide gently, and use within 2 minutes Visually or microscopically observe the results. The slide method blood type identification is a purely manual detection, which is fast and convenient to operate. However, the slide method cannot be used for anti-typing antibody detection, wh...
