[0057] Example: A blood collection pen that uses a tail handle to load and adjust the depth

[0058] like 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 lever 27, an outer shell 17, a button 23, a firing spring 30, a return spring 29, an inner sleeve 9, an outer sleeve 8 and a needle unloading push handle 22 (See figure 2 ). 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 sleeve 9 and the outer sleeve 8 are connected to form the tail handle 10 in the present invention.

[0059] The pen cap 1 is a sleeve-type cap on the head of the blood collection pen. figure 1 and figure 2 ). The middle sleeve 2 is the base used for connecting and cooperating with the pen cap 1 at the front of the blood collection pen, and the pen cap 1 and the middle sleeve 2 ...

Abstract

A blood collection pen that uses a tail handle to load and adjust the depth, including a housing, a shooting rod, and a tail handle, and is characterized in that: between the tail handle and the housing, the axial distance between the guide protrusion and the guide groove is used. The position is poor, and a special composite fit section is established. On the composite mating section, the guide protrusion and the guide groove have two working states: non-cooperating and cooperating. Among them, the non-cooperating working state is used to meet the need for the tail handle to rotate in the circumferential direction relative to the housing when adjusting the puncture depth, and the cooperating The working state is to meet the need for the tail handle to slide axially relative to the housing when the shooting rod is loaded, so that the two different movements of rotating to adjust the puncture depth and axial sliding loading are combined on the same tail handle. This solution breaks the limitations of the traditional structure and provides a novel and reasonable structural design. Its technical concept is unique and ingenious, and it reduces the number of parts, simplifies the structure, and is also convenient for identification and operation.

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 can be loaded directly with the tail handle and the puncture depth can be adjusted, with one button for multiple functions, easy to identify and easy to operate. 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 the blood collection pen has a history of 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 blood collection pen, how to improve the convenience of the blood collection pen and the u...
