Embodiment 1

[0067] Example 1: A blood collection pen that prevents misoperation and unloading of the needle after loading

[0068] Such as Figure 1-Figure 18 As shown, the blood collection pen is composed of a pen cap 1, a middle sleeve 2, a shooting rod 6, a needle unloading rod 27, a shell 17, a button 23, a launching spring 30, a return spring 29, an inner sleeve 9 and an outer sleeve 8 (see figure 1 ). Wherein, the pen cap 1 , the middle cover 2 and the shell 17 are connected to form the shell of the present invention, and an ejection cavity is arranged in the shell. Both the inner cover 9 and the overcoat 8 are connected to form the tail handle 10 in the present invention (see Figure 9 and Figure 10 ).

[0069] The pen cap 1 is a sleeve-type cap on the head of the blood collection pen. figure 1 ). The middle sleeve 2 is a base used for connecting and cooperating with the pen cap 1 at the front of the blood collection pen. The pen cap 1 and the middle sleeve 2 are connected t...

Embodiment 2

[0117] Example 2: A blood collection pen that prevents misoperation and unloading of the needle after loading

[0118] Such as Figure 24-Figure 36 Shown, embodiment 2 compares difference with embodiment 1 as follows:

[0119] 1. The setting position of the lock port 33 is different

[0120] attached Figure 24 It shows the three-dimensional view of the casing of Embodiment 2 of the blood collection pen of the present invention, with the attached Figure 25 It shows the sectional view of the shell of Embodiment 2 of the blood collection pen of the present invention. It can be seen from the figure that the locking opening 33 is arranged on the inner edge of the casing 17 . According to the definition of the present invention, the shell is composed of the pen cap 1, the middle sleeve 2 and the shell 17, so the shell 17 also belongs to a part of the shell, and belongs to the shell like the middle shell 2 in terms of structural properties, the difference is only the position o...

Abstract

A blood collection pen that prevents misoperation and unloading of needles after being loaded, including a housing, a shooting rod, and a needle unloading bar. A main actuating part is arranged on the arm of the arm, and the arm end of the elastic arm is used as a dead bolt. Simultaneously, an auxiliary actuating part is provided on the shooting rod for the main actuating part, and a lock opening is provided on the housing for the dead bolt. When the shooter moves backwards relative to the casing to load the chamber, the main actuating part contacts with the auxiliary actuating part and forces the elastic arm to bend and deform, thereby driving the lock bolt to extend into the lock opening to occupy a place, so that the shooter automatically enters the unloading needle after being loaded. protected status. This design solution solves the problem of needle unloading protection of the blood collection pen that does not need to open the cap to load and unload the needle, and the problem of inaccurate puncture depth caused by accidentally touching the needle unloading part of the blood collection pen with the rear-mounted puncture depth adjustment mechanism.

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 blood collection pen automatically enters the needle unloading protection state after the shooting rod is loaded, which effectively prevents the misoperation of unloading the needle and touching the unloading site by mistake, resulting in inaccurate puncture depth of blood collection. 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. The blood collection pen has been developed for decades, and the improvement of the blood collection pen has gone through many stages. At present, the blood collection pen is gradually becoming mature, but in the development process of the ...
