Embodiment

[0040] Embodiment: A kind of blood sampling pen with bias guide and anti-secondary puncture

[0041] Such as Figure 1-8 As shown, the blood collection pen is composed of a pen cap 1, a cap base 2, a shooting rod 3, a middle sleeve 4, a firing spring 5, a needle unloading rod 6, a shell 7, an inner sleeve 8, a return spring 9 and a tail handle 10 (see figure 1 ).

[0042] The pen cap 1 is a sleeve-type cap on the head of the blood collection pen. The front end of the pen cap 1 is provided with a blood collection end surface for contacting the blood collection part of the human body, and the blood collection end surface is provided with a pinhole. The cap base 2 is a base used for connecting and matching with the pen cap 1 at the front of the blood collection pen (see 1), and the pen cap 1 and the cap base 2 are connected through a connection port. The shooter 3 is the launching part of the blood collection pen, and the head of the shooter 3 is provided with a needle seat 14...

Abstract

The invention discloses an offset correcting and secondary puncture preventing blood collecting pen, which comprises a jetting rod and a shell, wherein the shell is composed of a pen head and a pen body; an ejection cavity is arranged in the pen body; the jetting rod is arranged in the ejection cavity; a latching structure, which is used for loading and locking the jetting rod, and a guide structure, which is used for guiding the jetting rod in shooting, are arranged between the jetting rod and the pen body; the blood collecting pen is characterized in that in coordination with the guide structure, an elastic sheet and a sliding supporting face are arranged between the jetting rod and the pen body; and a bump or / and a groove for reducing speed and taking a buffer effect is / are designed onthe sliding supporting face. Under a shooting state of the jetting rod, the elastic sheet makes into sliding contact with the sliding supporting face in one aspect, so that the surface of one side ofa guide block makes into contact with and gets into sliding fit to the surface of the corresponding side of a guide groove, and subsequently, the linearity of shooting is guaranteed; and in the otheraspect, the elastic sheet gets into collision fit to the bump or / and the groove, so that a buffer effect is achieved, and a phenomenon of secondary puncture is effectively prevented.

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 provide the straightness of the blood collection shooting and can effectively prevent secondary punctures during use. Background technique [0002] Among medical blood collection devices, a blood collection pen is a blood collection device used in conjunction with a disposable blood collection needle, wherein the blood collection pen is reusable, while 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 several decades, and the improvement of the blood collection pen has gone through many stages and gradually matured. [0003] Chinese patent CN203841702U announced on September 24, 2014 that it authorized a utility model patent with the application number 201420115833.8 and the na...
