Problems solved by technology

[0004] However, these existing one-touch blood collection needle holders are all different from the existing blood collection needles in structure. Like the existing lancet, it is screwed on the holder and fixed, so the lancet is not fixed firmly, and there are defects

Embodiment Construction

[0030] See figure 1 , figure 2 As shown, the lancet holder of the present invention is composed of a cylinder body 1 and a lancet fixing device 2 installed at the front end of the cylinder body 1. The lancet fixing device 2 includes a partition wall 11 along the front end of the cylinder 1 (see Figure 6 Shown) two sliding parts that slide; namely, the first sliding part 22, the second sliding part 23, when one sliding part (first sliding part 22) slides on the other sliding part (second sliding part) side , In a structure that can be combined with the male coupling device of the socket of the blood sampling needle, on the contrary, the other sliding member (second sliding member 23) slides on the side of one sliding member (first sliding member 22) At this time, it is in a structural state that cannot be combined with the male coupling device of the socket of the blood sampling needle.

[0031] See Figure 3 to Figure 19 As shown, the specific structure of the lancet holder of ...

Abstract

A holder for a blood collection needle includes a cylinder and a needle fixing mechanism disposed at a distal end wall of the cylinder. The needle fixing mechanism includes a first slider, a second slider, a retainer, and a frame. The first slider and the retainer have half female members integrally formed thereon. The first slider is movable toward the second slider such that the mechanism is in a closed state in which the first slider engages the frame such that the half female members come together to define a complete female member. The second slider is movable toward the first slider such that the mechanism is in an open state in which the first slider is disengaged from the frame. The invention can secure the blood collection needle more firmly.

Description

Technical field [0001] The invention relates to an instrument for taking out a medium from the body in the field of health care and medicine, in particular to a blood sampling needle holder with a blood sampling needle mounting device and a blood sampling needle holding device used for drawing blood from the human body, checking blood, and checking ESR. Background technique [0002] In the existing lancet holder, the external thread provided on the socket of the lancet and the internal thread provided in the holder are screwed with each other, so that the two are combined and fixed with each other, and at the same time, the lancet can be screwed. Rotate in the direction of closing and release to remove the lancet. When the used lancet is taken out from the holder, because the lancet is covered with a shield, mistakes are likely to occur when rotating by hand, and the palm, fingers, etc. may be injured by the lancet. Therefore, for the operator, there is a risk of being infected w...
