Abstract

The invention relates to a blood sampling pen convenient for unloading pricking cap. The blood sampling pen comprises a shell, a shooting rod and a needle unloading rod, and is characterized in that an elastic lug and a blocking surface are arranged between sliding matching surfaces of the needle unloading rod and the shooting rod, wherein the elastic lug is arranged on one sliding matching surface, the blocking surface is arranged on the other sliding matching surface, and the elastic lug and the blocking surface are positioned on a same sliding path. In a needle unloading state, as the needle unloading rod moves forwards relative to the shooting rod, the elastic lug and the blocking surface move towards each other; and when the distance between the elastic lug and the blocking surface iszero on the sliding path, interference is generated, the needle unloading rod forced to move forwards relative to the shooting rod is stopped, a blood sampling needle moves forwards away from the original position in a needle seat, and the needle tip of the blood sampling needle is exposed from a blood sampling end face so as to facilitate cap pricking. The scheme solves the problem that the prior cap unloading-free blood sampling pen is inconvenient to operate due to the fact that the prior cap unloading-free blood sampling pen has no stopping of cap pricking and observation of the needle tip is limited when the needle is unloaded.

Description

technical field [0001] The invention relates to a medical blood collection device, in particular to a blood collection pen matched with a disposable blood collection needle. The invention is particularly suitable for loading and unloading the needle-type blood sampling pen without removing the cap, and is convenient for the operation of piercing the cap when unloading the needle. Background technique [0002] The blood collection pen is a blood collection device used in conjunction with a disposable blood collection needle, wherein the blood collection pen is reusable, and the blood collection needle is only for one-time use in order to avoid cross-infection. In the current prior art, from the perspective of the convenience of loading and unloading needles, there are two types of blood collection pens: a cap-free type and a cap-removable type. Among them, the cap-free blood collection pen does not need to remove the pen cap when installing the needle, and directly inserts t...
