Embodiment Construction

[0025] Hereinafter, the structure and working principle of the needle recovery device of the present invention will be explained by taking the recovery of a blood sampling needle as an example with reference to the accompanying drawings. However, those skilled in the art should understand that the present invention is not only limited to the recovery of lancets, but can also be applied to other needles that need to be recovered.

[0026] figure 1 It is a cross-sectional view of the needle recovery device of the present invention before recovery starts. The illustrated needle recovery device includes a needle holder assembly 1 and a recovery tube assembly 2. The needle holder assembly 1 includes a lancet 3 (see Figure 14-17 ) Of the connector 10 and the hollow needle holder barrel 11 and a connector seat 12 formed at one end (front end, left end in the figure) of the needle holder barrel 11 for detachably fixing the connector 10.

[0027] The recovery tube assembly 2 includes an e...

Abstract

The invention discloses a needle recovery device, a needle holding assembly and a recovery pipe assembly. The needle holding assembly and the recovery pipe assembly are used for recovering needles. The needle holding assembly comprises a connector, a needle holder cylinder, a connector seat, a first separation component and clamping components formed on the connector. The recovery pipe assembly comprises an external recovery pipe, an internal recovery pipe, a compressed spring, a sliding part, a piston rod component and clamping components formed on the piston rod component. According to the needle recovery device, the needle holding assembly and the recovery pipe assembly, when the recovery pipe assembly gets close to the connector in the needle holder cylinder, a pair of clamping components fixes the connector and the piston rod component together, and then the first separation component separates the piston rod component from the internal recovery pipe; as a result, the compressed spring is released, and under the action of tensile force of the compressed spring, the piston rod component with the connector where a needle is fixed is recovered into the internal recovery pipe; and accordingly, accidental stabbing caused by the needle is prevented.

Description

Technical field [0001] The invention relates to a needle recovery device and a needle holder assembly and a recovery tube assembly for recovering needles. Background technique [0002] It is an extremely common medical practice to analyze and judge the health or cause of the subjects and other subjects through blood tests. To this end, it is first necessary to collect, for example, venous blood of the subject through a blood sampling device. A typical blood collection device includes a blood collection needle, a needle holder, and a vacuum blood collection tube capable of automatically drawing blood through the blood collection needle. When collecting blood, first fix the blood collection needle to the connector seat of the needle holder through the connector, then perform venipuncture on the subject, and then install the vacuum blood collection tube into the needle holder, so the venous blood is vacuumed in the vacuum blood collection tube Automatically flow into the vacuum bl...
