Embodiment

[0069] Example: a needle-type blood collection pen that does not need to be removed from the cap

[0070] Such as Figure 1-15 As shown, the blood collection pen consists of a pen cap 1, a cap base 2, a shooter rod, an indicator ring 6, a launch button 7, a casing 8, a shooter rod reset spring 9, a launch spring 10, a spring sleeve 11, a needle unloading reset spring 12, a Needle bar 13, inner casing 14, tail handle 15, adjusting ring 17 and handle return spring 18 are formed (see figure 1 ).

[0071] The pen cap 1 is a sleeve-type cap on the head of the blood collection pen. figure 1 ). The cap base 2 is a base body used for connecting and matching with the pen cap 1 at the front of the blood collection pen (see figure 2 and image 3 ), the pen cap 1 and the cap base 2 are connected through the connection port. The shooter is the launching part of the blood collection pen (the specific structure of the shooter will be described in detail later), and the head of the s...

Abstract

The invention relates to a dismounting-free cap assembling and disassembling needle type blood sampling pen, which comprises a shooting rod, an disassembling needle rod and a shell, and is characterized in that the shooting rod is formed by connecting a front shooting rod, a connecting spring and a rear shooting rod to form a variable-length shooting rod; a needle outlet hole at the front end of the blood sampling pen is designed into a assembling and disassembling hole through which a blood sampling needle can pass; the rear shooting rod is provided with a rear rod front limiting structure, so that the rear shooting rod has a limiting distance in forward movement; the front shooting rod is provided with a front rod front limiting structure, so that the front shooting rod has the limitingdistance in the forward movement; and in a needle disassembling state, the limiting distance of the front shooting rod is designed to be larger than the limiting distance of the rear shooting rod. Thedismounting-free cap assembling and disassembling needle type blood sampling pen is characterized in that the blood sampling needle is assembled and disassembled without disassembling a pen cap; andcompared with an original blood sampling pen, a needle assembling process is reduced to one step from original four steps, and a needle disassembling process is reduced to one step from original threesteps. By the adoption of the dismounting-free cap assembling and disassembling needle type blood sampling pen, the problem that the pen cap needs to be repeatedly disassembled and assembled during use of the original blood sampling pen is thoroughly solved, operation steps are greatly simplified, and great convenience is brought to the use.

Description

technical field [0001] The invention relates to a medical blood collection device, in particular to a cap-free needle-type blood collection pen used in conjunction with a disposable blood collection needle. The blood collection pen does not need to remove the pen cap during use, and the disposable blood collection needle can be directly loaded and unloaded from the front end of the pen head, which brings great convenience to use. 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 development of blood collection pens has a history of several decades, and the improvement of blood collection pens is also constantly developing. How to make the blood collection pens easy to use in the technical field of blood collection pens is one of the hot spo...
