Batch sample adding device

Abstract

The invention provides a batch sample adding device. The device comprises a box body, a handle is arranged on the box body, and a plurality of suction devices are arranged in the box body; the suctiondevice comprises a suction cylinder, a suction nozzle exposed out of the box body is arranged at the front end of the suction cylinder, and a magnetic piston rod is arranged in the suction cylinder;a coil framework end cover is arranged at the rear end of the suction cylinder, and the magnetic piston rod is sleeved with a reset spring; and the coil framework end cover is provided with a plurality of coil grooves which are arranged at intervals in the axial direction of the magnetic piston rod, each coil groove is provided with a coil, the first poles of coils on the same coil framework end cover are connected to one another, the coil framework end cover is further provided with a contact plate, the contact plate is provided with elastic contacts connected to the first poles and second poles of the coils, and the center of the coil framework end cover is provided with a sliding hole in sliding fit with the magnetic piston rod. The device has the advantages of being convenient to operate, capable of adding samples to rows of test tubes, accurate in sample adding amount and high in sample adding efficiency.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to a batch sample adding device. Background technique [0002] The sampling device is a device used to add the medium in the test tube. The traditional sampling device is generally a single manual sample addition. The most common way is to squeeze the sample in the sample bottle into the test tube by squeezing the sample bottle, so its The efficiency of adding samples is slow, the repeatability is high, and there are still problems such as the difficulty of accurately controlling the amount of samples added, and the fatigue of batch operations; [0003] Although there is a batch sample aspirator at present, it can only meet the transfer of samples between the same number of test tubes, and cannot realize the purpose of adding samples in batches. Contents of the invention [0004] Based on the above problems, the purpose of the present invention is to provide a batch sample feeding ...
