Abstract
The utility model discloses an automatic plasma separator judges through the colour of the interior liquid of colour sensor subassembly discernment pipe whether the separation is accomplished, colour sensor subassembly and electromagnetic switch communication, and electromagnetic switch closes the pipe after accepting the information of separation completion, avoids because the production misjudgement and the maloperation of the process of manual operation current stopping clamp shutoff pipe lead to the separation failure, improves plasma separation efficiency.
Description
Technical Field
The utility model relates to a whole blood separation technical field especially relates to an automatic plasma separator.
Background
Blood samples are commonly used in clinical medicine and scientific research fields, and blood plasma and red blood cells are often separated when analyzing blood samples. The whole blood bag, the plasma bag is usually hung with red blood cell preservation liquid bag when separating plasma and red blood cell, treat that the whole blood in the whole blood bag forms the layered structure on plasma layer and red blood cell layer, extrude the whole blood bag and squeeze plasma into the plasma bag in, operating personnel cuts off when judging that plasma separation finishes and ends the clamp and cut off the pipe, produce the maloperation easily, and judge through the vision whether the accuracy of accomplishing is not enough, especially can lead to the misjudgement because of visual fatigue after experiencing many times of repetitive operation, lead to the failure of separation process.
Disclosure of Invention
Utility model purpose: the utility model aims at providing a can judge the separation automatically and accomplish and turn off the plasma separator of pipe.
The technical scheme is as follows: the utility model discloses an automatic plasma separator, which comprises a color sensor component and a conduit fixing device, wherein the color sensor component is used for judging whether separation is finished or not by identifying the color of the conduit; the color sensor assembly is in communication connection with the electromagnetic switch and comprises a light source emitting device and a light source receiving device.
The automatic plasma separator also comprises a base, wherein the base is provided with a tray for placing a plasma bag and a pressing plate for extruding the whole blood bag, and the pressing plate is connected with the base through a spring hinge; the device comprises a pull rod for separating a pressing plate, wherein a pressing rod locking hook is arranged on a base, one end of the pull rod is connected with the pressing plate, the other end of the pull rod is fixed through the pressing rod locking hook, a magnetic sensor for detecting whether the pull rod is separated from the hook or not and starting a color sensor assembly when the pull rod is separated from the hook is detected is arranged at the pressing rod locking hook, the magnetic sensor is in communication connection with the color sensor assembly, and a first hanging rod for hanging a whole blood bag and a second hanging rod for hanging a red blood cell preservation solution bag are arranged on the base;
furthermore, the automatic plasma separator also comprises a power supply input assembly for supplying power, a power switch for controlling on and off, a reset switch for resetting the electromagnetic switch in an off state and an acousto-optic indicating device for prompting the completion of separation, wherein the reset switch and the acousto-optic indicating device are in communication connection with the electromagnetic switch.
Has the advantages that: compared with the prior art, the utility model has the advantages of as follows: the separation process can be accurately judged, the catheter can be timely turned off, red blood cells are prevented from entering a plasma bag, the separation failure caused by misjudgment and misoperation in the process of turning off the catheter by manually operating the flow stopping clamp is effectively avoided, and the plasma separation efficiency and the success rate are improved.
