Blood collection pen and blood collection component

Abstract

The invention relates to the technical field of medical instruments, in particular to a blood collection pen and a blood collection component. The inside of a pen body of the blood collection pen is provided with an ejection rod and an elastic device. A bogging key and a key are arranged on the pen body. The bogging key is capable of moving backwardly along the axial direction of the pen body so that the ejection rod is driven by the elastic device to move backwardly along the axis direction of the pen body, is capable of contacting with the key or the pen body. The key is capable of moving downwardly along the axial direction perpendicular to the pen body so that the ejection rod contacting with the key or the pen body is driven by the elastic device to move forwardly along the axis direction of the pen body. The inside of the pen body is provided with a guide device extending along the axis direction of the pen body. The guide device is capable of limiting the movement of the ejection rod along the axis direction perpendicular to the pen body. The blood collection component comprises a blood collection needle and the blood collection pen. The invention is aimed at providing the blood collection pen and the blood collection component to solve the technical problems in the prior art that the structure is complicated, the single-hand operation of a user is not easy, and the positioning precision of the ejection rod is not high.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a blood collection pen and a blood collection assembly. Background technique [0002] The blood collection pen is a medical device that collects a small amount of peripheral blood at the fingertips, and can provide a small amount of blood samples for diabetic patients to personally detect blood sugar. [0003] At present, there are mainly two types of blood collection pens in the domestic and foreign markets: [0004] The first type is an ordinary blood collection pen, which is cylindrical as a whole and consists of three parts: a depth adjustment device, an ejection device, and a pen holder. When in use, unscrew the cap of the pen, install the blood collection needle, then tighten the cap and adjust it properly. Then pull the cap at the end of the pen to complete the loading, then press the top of the cap of the lancing pen on the finger, press the launch button to coll...
