Embodiment 1

[0032] Such as figure 1 , figure 2 , image 3 As shown, the present embodiment relates to a safety blood collection needle, comprising a needle base 1 and a double-ended needle tube 2 passing through the needle base, one end of the double-ended needle tube is a venipuncture needle 21, and the venipuncture needle 21 is located The front end is used for venipuncture; the other end is a cannula needle 22, which is used to connect with a vacuum blood collection tube to cooperate with blood collection. The venipuncture needle 21 is provided with a puncture needle cap 6 outside, and the puncture needle cap 6 is stuck on the needle holder 1; Before the needle is used, the puncture needle cap 6 is set on the outside of the double-ended needle tube 2 to protect the sterilized double-ended needle tube 2 from contamination.

[0033] The safety blood collection needle also includes a safety sheath 3, a connecting mechanism 4 and a deck 5, the deck 5 is fixed on the needle hub 1, the s...

Embodiment 2

[0039] Such as Figure 8 , Figure 9 As shown, most of the technical features of embodiment 2 are the same as those of embodiment 1, and the difference of its technical solution is that: the card seat 5 is a ring, which is sleeved on the outer surface of the needle seat 1, and the size and shape of the ring are similar to those of the needle Corresponding to the outside of the holder 1, the card holder 5 is fixed on the needle holder 1, and the needle holder 1 is made of a transparent material. The connection mechanism 4 , the safety sheath 3 and the cartridge 5 are of an integrated structure, and the safety sheath 3 is also fixed on the needle holder 1 . The needle base 1 is made of a transparent material, and the medical staff can see through the needle base 1 whether there is blood return.

[0040] Such as Figure 8 Shown is the initial state of the safety injection needle described in this embodiment, the puncture needle cap 6 is buckled on the double-ended needle tube ...

Abstract

The invention relates to a safe blood taking needle. The safe blood taking needle comprises a needle seat, a double-head needle tube, a safe jacket, a connecting mechanism and a clamping seat, wherein the double-head needle tube penetrates in the needle seat; one end of the double-head needle tube is a venipuncture needle; the other end of the double-head needle tube is an intubation needle; the clamping seat is fixed on the needle seat; the safe jacket is connected to the clamping seat through the connecting mechanism, can rotate around the connecting mechanism and is a hollow cavity; and at least one needle tube safe hook is arranged in the cavity. The safe blood taking needle has the advantages that the problem of accidental needle puncture in the prior art can be effectively solved, and the risk that medical staffs contract diseases due to accidental needle puncture is avoided.

Description

technical field [0001] The invention relates to a medical device, in particular to a safety blood collection needle. Background technique [0002] In the process of blood collection, blood collection needles and blood collection tubes are essential and important instruments. In the past, traditional syringes were commonly used to draw blood, and then transferred to blood collection tubes for inspection and other operations; in recent years, one-step direct blood collection with vacuum tubes has become a more advanced blood collection method. Vacuum tube one-step direct blood collection method adopts blood collection equipment such as double-ended blood collection needle, vacuum blood collection tube, blood collection sheath (needle holder). Existing double-ended blood collection needles are common blood collection needles, mainly comprising a blood collection needle connection sleeve and a venipuncture needle and an intubation needle of an integral structure. The venipunct...
