Description

Be used for blood to detect inner wall polishing application of sample needle Technical Field The utility model belongs to the technical field of sample adding needles, and particularly relates to a polishing sample adding needle for blood detection inner wall. Background Blood consists of plasma and blood cells. Wherein the blood plasma contains nutrient components such as plasma protein, lipoprotein, inorganic salt, oxygen, hormone, etc., and the blood cell contains erythrocytes, leukocytes and platelets. Physiological and pathological changes in living bodies often cause changes in blood components, and thus blood detection data are important indicators reflecting health conditions. A needle is typically used during blood testing. In the prior art, medical staff is usually required to manually operate the sample adding needle to collect a blood sample, and in the transfer process after collection, the needle head collecting part of the sample adding needle lacks protection, so that cross contamination is easy to occur in the process of transferring the blood to a reaction container, and the accuracy of a detection result is influenced. Disclosure of Invention The utility model aims to provide a polishing sample-adding needle for blood detection inner wall, which can protect the collection part of a needle head in the process of transferring a blood sample, avoid cross contamination and ensure the accuracy of a detection result. The technical scheme includes that the needle comprises a needle tube, a protection component is arranged on the surface of the needle tube, the protection component comprises a fixed seat, the side surface of the fixed seat is fixedly connected with the outer surface of the needle tube, a screw is movably connected to the inside of the fixed seat, a movable seat is connected to the outer surface of the screw in a threaded mode, a fixed plate is fixedly connected to the side surface of the movable seat, a semicircular groove is formed in the lower surface of the fixed plate, a first check ring is fixedly connected to the upper surface of the fixed plate, a containing groove is formed in the side surface of the movable seat, rotary teeth are movably connected to the inside of the containing groove, a movable plate is movably connected to one end of the movable plate, the gear ring is meshed with the rotary teeth, a bottom plate is fixedly connected to the side surface of the movable plate, and a second check ring is fixedly connected to the upper surface of the movable plate. Optionally, the lower extreme fixedly connected with needle body of needle tubing, the inner wall of needle body adopts polishing treatment.
