Problems solved by technology

[0003] First, the two types of lancets currently on the market are triggered by pushing the push button with the thumb, the angle between the trigger button and the blade is 120°, and the thumb and middle finger are fixed on the side of the product. The medical personnel use the blood collection needle to generate a rotational force, which leads to unstable positioning and misoperation during blood collection, which affects the success rate of blood collection
And the safety device and the trigger key are at the same place, if the medical personnel do not operate properly during use, it is easy to cause false triggering.
[0004] Second, the blade for blood collection is exposed in the air without any protection, and its service life can only be guaranteed by the sealing of the outer package (up to 5 years). The exposed blade will bring great harm to product assembly and use. Inconvenient, in case of cont...

Abstract

The invention discloses baby heel hemostix. The hemostix comprises a shell, an insurance component, a triggering key, a blade, a knife rest, a poking shaft and a torsion spring, the insurance component comprises a pull ring, a key retaining rib and a blade protection shell, the triggering key is locked through the key retaining rib, and the blade is covered with the blade protection shell; a 90-degree included angle is formed between the key direction of the triggering key and the blade outgoing direction of the blade; the poking shaft can drive the knife rest to be linked; the end, close to the blade, of the knife rest is provided with a bevel pin shaft, and the bevel pin shaft is arranged in a profiling groove in the shell in a sleeved mode, so that the blade moves according to the track of the profiling groove; when in the locked state, and a clamping corner at the lower end of the poking shaft is stuck by a protrusion at the lower end of the triggering key, so that the torsion spring is located in the energy storage state. By means of the hemostix, the blade can be prevented from being polluted, when a medical worker conducts blood sampling, accurate location can be achieved, misoperation is avoided, and painless blood sampling is achieved in the real sense.
