Body fluid sampling device for clinical laboratory

Abstract

The invention discloses a body fluid sampling device for the clinical laboratory. The body fluid sampling device for the clinical laboratory comprises a needle head assembly, a fluid taking pipe, a movable cover assembly, an inlet pipe assembly, a blockage cleaning assembly and a fluid storage pipe assembly; the movable cover assembly is movably connected to the outer surface of the needle head assembly in a sleeving mode; the fluid taking pipe is fixedly connected with the needle head assembly; the other end of the fluid taking pipe is movably connected with the fluid storage pipe assembly; the inlet pipe assembly is fixedly arranged at one end of the fluid storage pipe assembly; and the blockage cleaning assembly is movably arranged in the inlet pipe assembly. According to the invention, a needle cover can be prevented from accidentally falling and losing; meanwhile, a medical worker is prevented from being accidentally punctured by the needle tube; fluid is prevented from accidentally leaking; the possibility of blood disease infection is reduced; in addition, the temperature in a fluid storage cavity is maintained; the fluid in the fluid storage cavity is effectively prevented from being solidified; the blockage phenomenon of a pipeline end is solved; and finally, the fluid taking pipe is prevented from being accidentally broken and separated.

Description

technical field [0001] The invention relates to the technical field of medical sampling and detection, in particular to a body fluid sampling device for laboratories. Background technique [0002] The Laboratory Department is a bridge between clinical medicine and basic medicine, including clinical chemistry, clinical microbiology, clinical immunology, hematology, humoral science and blood transfusion and other sub-disciplines; [0003] The liquid in the human body is composed of water, inorganic salts and organic substances dissolved in water, collectively referred to as body fluids. Water is the main component of body fluid and the most abundant substance in the human body. Body fluid is widely distributed inside and outside the cells of the body. Intracellular fluid is the main part of substance metabolism, and extracellular fluid is the internal environment for the survival of each cell in the body. The dynamic balance of distribution and composition is a necessary cond...

Problems solved by technology

[0005] (1) In the existing body fluid sampling device, the needle and the needle cover are separated. Therefore, in the process of using the needle to extract body fluid, the medical personnel generally hold the needle cover. However, the negligence of the medical personnel may occur. Cause the accidental drop of the needle cover, therefore, the needle has no protective device, and the dropped needle cover is polluted by external bacteria;

[0006] (2) In the process of covering the needle with the traditional needle cover, the liquid on the surface of the needle is likely to accidentally slip and drip on the clothes and sheets, which is conducive to the spread of blood diseases and affects the health of others;

[0007] (3) The existing body fluid sampling device does not provide a device for preventing the liquid from solidifying in the body fluid storage device, which affects the removal of the internal body fluid and affects the detection work;

[0008] (4) In the existing body fluid sampling device, when the body fluid enters the storage device, the temperature at the inlet end may cause the coagulation of the blood clot and block the inlet, seriously affecting the work of extracting the body fluid;

[0009] (5) When the existing body fluid sampling device is taking liquid, the liquid taking tube is accidentally pulled, which can easily lead to accidental breakage or even separation at the connection between the liquid taking tube and the bottle body, so that the liquid taking work is interrupted and the liquid leaks accidentally
