Description

technical field [0001] The invention relates to medical equipment, in particular to a blood sampling device which is easy to assemble and disassemble needles. Background technique [0002] According to, the commonly used blood collection device is generally of simple design, and the needle is non-replaceable when used, and another blood collection device is required, so the cost is greatly increased, and it is not environmentally friendly. [0003] Therefore, various blood collection devices with replaceable needles have been released on the market. However, in some designs, the needles still have to be removed by holding the needles in the hand, so it is still inconvenient to operate, and the fingers may be injured by the needles, or the fingers may be damaged. It is easy to be stained with blood, etc., which is its main disadvantage. [0004] And another design can be operated with one hand, and the used needle can be separated from the syringe by simple operation, but pa...

Problems solved by technology

[0002] By the way, commonly used blood collection devices are generally simple in design, and the needles are not replaceable when used, and another blood collection device is required, which greatly increases the cost and is not environmentally friendly.

[0003] Therefore, various blood collection devices with replaceable needles have been released on the market. However, in some designs, the needles still have to be removed by holding the needles in the hand, so it is still inconvenient to operate, and the fingers may be injured by the needles, or the fingers may be damaged. It is easy to get blood, etc., which is its main disadvantage

[0004] And another design can be operated with one hand, and the used needle can be separated from the syringe by simple operation, but part of the separation action is less accurate and causes inconvenience in operation, and another design is also Problems such as high cost and difficult operation due to complexity
