Abstract

The invention relates to the technical field of blood collection medical instruments, in particular to a novel safe blood collector. An anticoagulation medicament is arranged in a blood collection glass tube. A puncture needle groove is formed in the upper end of the blood collection glass tube. A rubber sealing sliding block is arranged in the puncture needle groove. A switching valve is arranged in the rubber sealing sliding block. The upper end of the switching valve is connected with a puncture needle. The lower end of the switching valve is connected with a guide tube. One side of the switching valve is connected with a switching connecting rod. A rubber sealing plug is arranged at the upper end of the puncture needle groove. A protective cover is arranged at the upper end of the rubber sealing plug. The novel safe blood collector is simple in structure and novel in design. The hidden puncture needle is adopted and hidden in the blood collector, operation is quick and convenient, and the novel safe blood collector is suitable for small-dosage blood collection.

Description

Technical field: [0001] The invention relates to the technical field of blood sampling medical devices, in particular to a new type of safe blood sampling device. Background technique: [0002] In many conventional lancets, an elongated shaped sharp-pointed lancet body is included in a housing and is driven by a compression spring. The sharp tip is typically provided through the sharp end of the lancet, and the lancet body is molded around the sharp end of the lancet. When triggered, the lancet body performs longitudinal extension and retraction movement to provide a linear penetration action. The linear penetration action allows the use of a linear action spring and contributes to a very reliable blood collection device. The longitudinal movement and subsequent simple actions result in a smaller number of components, which facilitates manufacturing and assembly. [0003] However, the puncture needle and the blood collection tube of the traditional blood collection device are se...
