Micro-sampling device for lab

Abstract

The invention discloses a micro-sampling device for a laboratory, which comprises a casing, a controller, a display and an operation button are fixedly installed in the inner cavity of the middle part of the casing, and a storage battery is fixedly installed in the inner cavity of the bottom of the casing. A motor is fixedly installed in the inner cavity of the upper part of the shell, and the right side of the motor is fixedly connected with the worm through a coupling. A worm wheel is movably installed on the upper side of the worm wheel. The left end of the straight gear rod is fixedly connected with a piston, the outside of the piston is movably connected with a needle tube, the left end of the needle tube is fixedly installed with a measuring tube, the outside of the measuring tube is provided with a scale, and the left end of the measuring tube is fixed A needle is connected, and a handle is fixedly connected to the left side of the needle. The invention is simple in structure, convenient and practical, reduces the labor intensity of medical personnel during repeated operations, and is beneficial to improving the inspection efficiency of the laboratory department of the hospital.

Description

Technical field [0001] The invention relates to the technical field of medical equipment, in particular to a micro sampling device for a laboratory. Background technique [0002] The laboratory is a comprehensive laboratory integrating health care, medical treatment, teaching, and scientific research. It undertakes a large number of tests on various human and animal specimens including wards, outpatient and emergency patients, various physical examinations, and scientific research. It is for clinical diagnosis, The organization that prevents or treats human diseases or injuries, and evaluates human health and inspects and determines human substances is not only an important auxiliary department of the hospital, but also a functional laboratory necessary for scientific research in the hospital. With the help of a variety of testing and scientific research equipment, according to the clinical The inspection form is the daily work content of the laboratory of the hospital to test th...

Problems solved by technology

[0003] At present, on the one hand, the hospital laboratory has blood and body fluid samples from individuals with different diseases, and on the other hand, it needs to perform routine testing on these samples with scientific research value. Therefore, the work of the laboratory is very heavy and delicate. Micro-sampling in the laboratory It is one of the very important inspection steps. Inaccurate micro-sampling will lead to inaccurate test results. Micro-samplers are required to cooperate with micro-inspection analysis. However, in the prior art, ordinary samplers are often used for visual consideration. Due to The accuracy is poor, which not only affects the speed of inspection and analysis, but also affects the quality of inspection and analysis. At the same time, the sampling process is relatively cumbersome and the efficiency is not high.
