Abstract

The invention discloses a blood taking needle with a protection function. The technical scheme is as follows, a rotary positioning rod which overturns outwards is hinged to the side surface of a needle handle, the end, away from the hinged end, of the rotary positioning rod is fixedly connected to a top plate axially perpendicular to the rotary positioning rod, the periphery of the top plate is connected to a baffle vertically extending towards the side of the hinged end of the rotary positioning rod, the top plate and the baffle enclose an accommodating space of the tip of the needle body, and baffle away from the rotating positioning rod is an elastic baffle. According to the invention, through a limiting plate, the blood sampling operation of a left-falling operator is considered, the puncture success rate is increased, the patient experience is improved, and the patient satisfaction degree is improved; a protective sleeve composed of the top plate and the elastic baffle sleeves theneedle tip in a poking mode, operation is easy, needling injuries caused by secondary back-sleeving are effectively avoided, the needle tip and the operator are isolated all the time in the treatmentprocess, and the needling injuries are avoided.

Description

technical field [0001] The invention relates to a medical device, in particular to a blood collection needle with protective function. Background technique [0002] At present, the needle tip of the blood collection needle widely used in clinical practice is completely exposed after blood collection, and because the output hose is mostly in the form of twists and turns in the packaging and storage, when handling the used blood collection needle, it is often caused by the output hose "molding". The function of "causes the needle to "rebound" and cause needle stick injury, which exposes medical staff to the risk of infection. Because the needle tip is exposed, the blood is easily thrown out to generate aerosol and cause secondary pollution; at the same time, in clinical work, some Nurses operate with their left hands, and the existing blood collection needles have a single wing on the right, but the oblique section of the needle tip needs to be set upwards, which is extremely ...
