Problems solved by technology

[0004] Although the above-mentioned tail-pressing blood collection device has a mature basic structure, a reliable ejection mechanism, and distinctive structural features, there are still some deficiencies in terms of safety in use: First, because the tail cap completely rebounds after being pressed, it cannot be directly identified from the appearance The form before and after use; second, even if the blood collection device is used, if a needle is used to push the needle hole from the front end, the needle core can be loaded and used again

[0056] Example: a tail-pressing disposable safety blood collection device

[0057] The blood collection device is composed of a shell 1, a needle core 2, a twist cap 11, a spring 3 and a tail cap 4 (see figure 1 and figure 2 ).

[0058] The shell 1 forms an ejection chamber, and the front end of the ejection chamber is provided with a pinhole 9 (see image 3 and Figure 4 ), there is a gap 20 in the pinhole 9 (see Figure 4 , Figure 12 and Figure 14 ). The needle core 2 is located in the ejection cavity, and the shell 1 is provided with two elastic arms 5 extending inwards (see image 3 , Figure 4 and Figure 11 ), the elastic arm 5 is provided with a hook 6 for locking the needle core 2 (see Figure 11 ), the needle core 2 is provided with an engaging surface 8 corresponding to the hook 6 (see Figure 5 , Figure 6 and Figure 11 ). In the ready-to-fire state, the front end of the spring 3 presses against the needle core 2, and the engagement surface 8 of th...

Abstract

A tail-pressing disposable safe blood collector comprises a shell, a needle core, a spring and a tail cap. An elastic arm for locking the needle core is arranged on the shell. The tail-pressing disposable safe blood collector is characterized in that an active shackling portion for shackling is arranged on the tail cap, and a passive shackling portion for shackling is arranged on the elastic arm correspondingly; position and matching time of the active shackling portion and the passive shackling portion are correlated to those of an active unlocking portion and a passive unlocking portion. When the tail-pressing disposable safe blood collector is in use, the tail cap is pressed to force the needle core to be unlocked to launch a puncture, then the tail cap and the elastic arm are in a locked state, and the blood collector cannot be used again. After the blood collector is used, the tail cap is permanently locked on the elastic arm of the shell, so that safety of one-time use is ensured, and the tail cap after being used can be visually recognized as in an obviously contracting state at the tail of the shell in appearance.

Description

technical field [0001] The invention relates to the field of medical blood collection instruments, in particular to a tail-pressing type disposable safety blood collection device. The blood collection device has its own ejection mechanism, which not only has an obvious mark after use, but also cannot be used again, thus ensuring the safety of the blood collection device at one time. Background technique [0002] Among medical blood collection devices, disposable blood collection devices are popular among medical staff and patients for their small size, safe use, and convenient operation. They are currently widely used in various medical institutions and diabetic patients. This kind of blood collection device has its own ejection mechanism, compact structure, and one-time use as a whole, which is safe and convenient, so it has strong market development potential. [0003] Chinese patent CN107007289A discloses an application for an invention patent entitled "Back pressure typ...
