Blood collection device convenient to use in clinical examination

Abstract

The invention discloses a blood collection device convenient to use in clinical examination, wherein the blood collection device includes a base; the outer wall of the top of the base is provided witha sliding groove; the interior of the sliding groove is in clearance fit with a sliding block; the outer side of the sliding block is welded with a cross bar; the outer side of the cross bar is welded with a disc; the disc and the upper surface of the base are each provided with through holes in a clearance manner; the top end of a connecting rod is welded with a first disc; the upper surface ofthe first disc is provided with round holes; the interior of each round hole is placed with a blood storage tube; the top of the interior of each blood storage tube is provided with a rubber plug; theinterior of the top of each rubber plug is bonded with a sealing device; the top of each sealing device is inserted with a needle tube; the top of each needle tube is inserted with a needle head. Fast blood and air isolation can be achieved, gas is prevented from being mixed into blood to affect the results of the test, and the test is more accurate.

Description

technical field [0001] The invention relates to the technical field, in particular to an easy-to-use blood collection device for clinical examination. Background technique [0002] Blood is a red, opaque, viscous liquid that flows through the blood vessels and heart of a person. Blood is composed of plasma and blood cells. One liter of plasma contains 900-910 grams of water, 65-85 grams of protein and 20 grams of low-molecular substances. There are various electrolytes and organic compounds in low-molecular substances. Blood cells include red blood cells and white blood cells Blood collection devices are needed in clinical examinations, but the existing blood collection devices still have the following problems: 1. The rapid isolation of blood and air cannot be achieved, and it is easy to cause gas to mix into the blood and affect the detection 2. When the medical personnel take blood, they need to take the test tubes to collect the blood in addition, the operation is cumbe...
